Faisal - Operational and process management Essay

Faisal - Operational and process management - Essay Example The paper also described views on how this company can better their stand in the crowded footwear industry and end up being a stronger competitor to its key challenges in its business environment. The paper presented a number of models and theories for both the analysis of the prevalent systems at Crocs, and offered insights on how they can integrate into success and create a more stable company. The paper also portrayed different perspectives by providing postulations against vertical integration as strategy to gain competitive advantage. 1.0 Introduction Crocs, Inc. was initiated in the year 2002 in Colorado and is arguably one of today’s fastest growing brands and organisations at the world level. The company initially produced footwear for all age categories under the same brand and is now sold well in over 100 countries. The brand features a special kind of plastic that is softened by body heat of the individual wearing the shoe, resulting in high degree of comfort. Sales for the company jumped 256% in 2006 (Thompson, 2006). There has been much discussion about Crocs’ success and besides the popularity of its shoes, the major reasons for the enormous growth of the company has been its efficient chain supply management. Crocs, Inc. has shown that being flexible and being focused on digressing from the conventional norms of the industry, they could achieve more success and profits than their peers (Ashkanasy and Wilderom). This efficiency was the result of their Chief Executive Officer’s vision of satisfying customers by developing an ultra efficient process of production that would facilitate the company to make and supply at short notice, hence creating a competitive advantage in the industry. The Crocs supply chain has been revolutionary in footwear production but there is need to evolve in line with changes in the global industry environment. In the long run, a conventionally thinking organisation has no future. Alteration in technol ogy, delivery procedures, customer demands, and legislative policies demand that a company focuses on its core competencies rather than venturing into all possible diversification schemes. 2.0 Industry analysis By the use of the Product Life Cycle (PLC) concept (Waters and Water, 1999), it is quite visible that the footwear industry as a whole is near saturation and this is likely to run for a long time. It is least likely that the demand for footwear will fall significantly but there are possibilities that with the development of cheaper and more durable products, the industry’s profitability will decline after some time. Using the following Five Forces Model analysis of the global footwear market, the following observations can be made. 2.1 Entry Barriers Entry barriers are engineered to elbow out potential starters from entering a market. These barriers seek to serve the monopoly powers of the incumbent organisations in that industry, thereby maintaining monopoly margins. Some known barriers include limit pricing, patents, cost advantages as well as marketing and advertising among others. This industry appears to offer relatively easy entry for new participants. The advantages of cost are fairly low with quite a large number of players locally and globally. However, it is worth noting that the manufacturers have significantly easy access to factors of production, particularly raw

Running Business in Brazil Essay Example | Topics and Well Written Essays - 1750 words

Running Business in Brazil - Essay Example Brazil is expected to invest US $18.4bn for the 2014 FIFA World Cup in 12 Brazilian host cities funding 50 projects (Portal Brasil, 2010). By the end of the 1990s Brazil was ranked tenth in global automotive producers as the nation was willing to experiment with a wide range of supply and production arrangements (Strategic Direction, 2005). Brazil is undoubtedly poised for growth ever since its foreign exchange policy is liberalized. It is moving towards becoming the fifth largest economy (Williams, 2011). However, all these pose a very glamorous image of the nation but businesses desirous of investing in Brazil need to get a complete picture of the benefits and pitfalls. Any disappointments could damage the credibility of the country that it is trying to build up. Economic situation There were more than 10 significant oil discoveries last year which has pushed the nation up in oil producer rankings (The Telegraph, 2011). Brazil is expecting a Tsunami of riches as Petrobras gets full production from the oilfields deep under the Brazilian Seas (O'Shaughnessy, 2009). This would help the nation overcome the repression and torture which impacted the living conditions. Flushed with excessive cash has its pitfalls. Its currency is the most overvalued and real-estate bubble is expected in Brazil as banks have extended risky loans (Lyons, 2011). Cost of doing business in Brazil has risen very fast. Brazil has abundance of natural resources and could be the world power but poor management and leadership have led to large debts (Balsom, n.d.). Economic growth in Brazil has been built on a very fragile structure as 10% of its population is completely illiterate and 68% functionally illiterate (The Brazil Business, 2011). Millions of students emerge from secondary schools without being able to write in English. What is astonishing is that it is socially accepted and expected that they would not learn anything in school. Unemployment in Brazil was 9.9% as of 2009 (McGladrey , 2010). However, through targeted social programs, through subsidizing house loans and raising the minimum wage the government has been able to pull more than 20 million people out of poverty (The New York Times, 2011). President Lula paved the growth that solidified the country and made it a significant player in the world. However, the next President again has not been able to win the confidence of the people. Thus, on the one hand while it has abundance of natural resources, a large industrial base, a huge population base, making the market attractive to investors, economic uncertainties make it difficult to improve its competitiveness or build a modern infrastructure (Austrade, 2001). Labor The nation has a large labor force but the workers are either unskilled or semi-skilled. There is a shortage of technical personnel. Labor unions can be militant especially in the metallurgical, automobile, banking and transport sectors (PricewaterhouseCoopers, 2005). They make a significant force in the country. Fringe benefits and social security for the laborers is not very strong. However, foreign investors do not experience problems with labor because they follow local standards and practices. and the country has been the top producer/exporter of soybeans, cattle and beef products, and poultry. Major issues in doing business in

Grievance handling procedure in Reliance Infocomm Limited

Grievance handling procedure in Reliance Infocomm Limited To develop a Grievance handling procedure for Reliance Infocomm after studying in detail the types and causes of grievances those are specific to Reliance Communication Limited. Objectives: To frame a Grievance Redressal Procedure for Reliance Infocomm Limited. To analyze the types of grievances that existed among the employees of Reliance Infocomm Limited. To obtain suggestions on the kind of Grievance Redressal Procedures from the employers of Reliance Infocomm Limited. Introduction: Every employee has certain expectations which he thinks must be fulfilled by the organization he is working for. When the organization fails to do this, he develops a feeling of discontent or dissatisfaction. When an employee feels that something is unfair in the organization, he is said to have a grievance. In the Industrial Relations language, Grievance is defined as anything which irritates or tends to make work conditions unsatisfactory and thereby harbors a discontent or dissatisfaction arising anything connected with the company that an employee thinks, believes or even feels, unfair, unjust. In this sense many of the controversial issues in Industrial Organizations may be said to arise as a result of incept or ill-advised handling or neglect of grievances which individually may appear trivial but collectively may become explosive. The basic objective of the project is to frame a Grievance Redressal Procedure for Reliance Infocomm Limited and to analyze the types of grievances that existed among the employees of Reliance Infocomm Limited. Telecommunications Industry IN India The telecommunications industries in India are highly competitive. The growth rates in the number of telecommunication lines (both fixed and mobile) have been growing quite significantly, teledensities have been steadily improving and the ratio of mobile to fixed communications has crossed unity. In addition to the distribution of telecommunications services, India has a sizeable telecommunications equipment manufacturing industry. India has followed a policy of establishing a stand alone public laboratory, which was charged with the responsibility of developing a family of digital switching equipments and then transferring this generated technology to domestic public and private sector telecom equipment manufacturers. The telecommunications industry is a good example of the fact while having cheap factor endowments is necessary for a country to establish its presence in the international market; ability to move up the innovation ladder is a sufficient condition for that to occur. India is been considered to be the emerging technological giant from the developing world. India spent about one percent of their GDP on RD and have a growing number of patents issued in the US to their local inventors. India is an acknowledged powerhouse in embedded software, business software in general, chip designs and in pharmaceuticals. India has one of the largest telecommunications networks in the world. Reliance Infocomm is part of a large Indian conglomerate namely Reliance Industries. The American telecoms company, Qualcomm that pioneered the CDMA technology, holds about 4 per cent of the shares of Reliance Infocomm. Qualcomm makes money from royalties every time a chipset is inserted into CDMA phones and other network equipment as well as from license fees. Further based on my discussions with Midas Communications, it could be seen that the order from Reliance Infocomm has led to a large quantum of orders from both elsewhere within the country and from abroad. For instanc e, following test-run with 25,000 CorDect systems in 24 cities across nine states for over an year, Bharat Sanchar Nigam Limited (BSNL) has recently awarded a contract for over 0.6 million CorDect lines. The BSNL contract is worth around Rs. 7 billion and is divided among Himachal Futuristic Communications Ltd (HFCL), Indian Telephone Industries Ltd (ITI), and Electronic Corporation of India (ECI), Shyam Telecom and Hindustan Teleprinters Ltd (HTL). Literature Review Introduction In a broader perspective, any discontent or dissatisfaction, real or imaginary, experienced, by an employer about his or her employment constitutes a grievance. In their working lives, employees occasionally become aggrieved at the treatment meted out to them by the supervisors or the management on certain service conditions managerial decisions, practices, etc., A grievance should be treated as a show cause issued by the workmen against the management by an undertaking. Grievances can arise mainly under two conditions, namely: When management attempts or does something which it is not expected to do. When the management fails or refrains from doing something which it is expected to do. Thus a grievance is also an indicator of the organizational health. The complainant may or may not specifically assign reasons for dissatisfaction. But once the complaint is formally presented it has got be investigated and a solution is found out. According to Beach, D.S, and Personnel Administration, of People at Work, 1965, Any dissatisfaction or feeling of injustice in connection with ones employment situation that is brought to the notice of management. According to S. Chandra, Grievance Procedure: A Survey of Practices in India, 1968, the following causes have been given of employee grievances: Promotions, Amenities, Continuity of services, Compensation, Disciplinary action, Fines, Increments, Leave, Medical Benefits, Nature of the job, Payment of wages, Acting promotion, Recovery of dues, Safety appliance, Superannuation, Super session, Transfer, Victimization and Conditions of work. The handling of special grievances may involve special steps as well as, or in place of, skipping certain steps within normal grievance channels, by Petterfer, J.C, Effective Grievance Arbitration in California Management Review, 1970. According to Shea, John, Would Foremen Unionize? in Personnel Journal, 1970, There are always time limits between different steps of the grievance procedure. Additional steps are taken within a grievance system when labour is dissatisfied with the solution put forward by the lower line management. According to Jucius, J.M., Personnel Management, 1971, A grievance is any discontent or dissatisfaction, whether expressed or not, whether valid or not, arising out of anything connected with the company which an employee thinks, believes or even feels to be unfair, unjust or inequitable. Any real or imagined feeling of personal injustice which an employee has concerning his employment relationship by Keith Davis, Human Relations at Work, 1971. A written complaint filed by an employee and claiming unfair treatment by Dale Yoder, Personnel Management and Industrial Relations, 1972. The Indian Institute of personnel Management, Calcutta, in the year 1973, has briefly summarized the grievance procedure in the following five steps: In the first instance, the grievance should be settled at the lowest level, that is, the employee should raise his grievance with his immediate superior. It should be made clear to the employee that he may appeal if he does not get satisfaction from his immediate superior. He should know who the next person in the echelon of management is to whom he should refer his grievance. The grievance should be speedily dealt with If the grievance is against any instructions issued by the superior, the employee should clearly understand that, in the interest of discipline, the instructions must first be carried out before the grievance can be considered and decided upon. It is only when this has been done that the employer will register his protest and set the grievance handling procedure in motion. It should be clearly understood by the employee that there will be no recourse to any official machinery till the grievance redressal procedure has been set in motion and that, in the event the employee is still dissatisfied, there will be no direct action by either party which might prejudice the case or raise doubts while the grievance is being investigate. The grievance is usually more formal in character than a complaint. It can be valid or ridiculous, and must grow out of something connected with company operations or policy. It must involve an interpretation or application of the provisions of the labour contract says Flippo, Principles of Personnel Management, 1976. Chapman, Brad J., 1976, observes: An employees concern for his job security may prompt a grievance over a transfer, work assignment, or promotion. Sometimes bad relations between supervisors and subordinates are to blame: this is often the cause of grievances over fair treatment. Organizational factors like automated jobs or ambiguous job descriptions that frustrate or aggravate employees are other potential causes of grievances. Union activism is another cause. For example, the union may solicit grievances from workers to underscore ineffective supervision. Problem employees are yet another cause of grievances. These are individuals, who, by their nature, are negative, dissatisfied, and grievance prone. According to Sikula, A.F., Personnel Administration, 1978, It is not possible that all the complaints of the employees would be settled by first-line supervisors, for these supervisors may not have had a proper training for the purpose, and they may lack authority. Moreover, there may be personality conflicts and other causes as well. According to Brian Bemmels, Janice R.Foley, a common criticism of grievance procedure research is the lack of theoretical grounding for much of the research done prior to 1985. Several earlier reviews of the grievance literature raised the challenge of improving on the theoretical aspects of grievance research. According to Michael Corcoran, 2006 a solicitor in the Steeles employment team, offers advice on grievance procedures: The aim of a grievance procedure is to encourage consistency, transparency and fairness in the handling of workplace problems or complaints. It should allow the employer to seek an informal resolution where appropriate but allow for more formal proceedings should the circumstances demand. The grievance procedures must be followed in relation to any grievance about action by any employer that could form the basis of a complaint by an employee to an Employment Tribunal. A grievance is a complaint by an employee about action which his employer has taken or is contemplating taking in relation to him. Research Methodology RESEARCH OBJECTIVES: To gain familiarity with a phenomenon or to achieve new insides into it. To portray accurately the characteristics of a particular individual situation or a group. To determine the frequency with which something occurs with which it is associated with something else. To test a hypothesis of a casual relationship between variables. RESEARCH TECHNIQUE: A research technique refers to the behavior and instruments we use in performing research operations. Here, regarding this project the techniques of Questionnaire is used with attitude skills, nominal scales, ordinal scales, and interval scales, and ratio scales mass behavioral scales. RESEARCH DESIGN: A research design is the arrangement of conditions for collection and analysis of date in manner that aims to combine relevance to the research purpose with economy in procedure. Regarding this project, descriptive research design is applied. Here, Descriptive research design is concerned with describing the dissatisfaction of each individual on his job and the diagnostic research design helps in diagnostic research design helps in determine the frequency with which something occurs or its associated with something else. These two research designs helps in understand the characteristics in a given situation, think systematically about aspects in a given situation, offers idea for probe and research help to make certain simple decision. The researcher adopted random sampling method which includes 100 executives of Reliance Communication Limited. Conclusion In conclusion it is very important to remove the misunderstandings between the misunderstandings between the employer and employee. Human relations are the most important. It is the duty of the employer to remove the conflict from the minds of his employees and to localize problems and to find out ways and means for redressal of grievance. For achieving this goal an effective grievance procedure will certainly contribute to industrial peace and contended or happy labour.

meeting diverse needs in a classroom Essay -- essays research papers

Having observed inside a kindergarten classroom for a couple of weeks thus far, it has already become apparent to me the plethora of diverse needs of the children within a single classroom. Not all students are alike. They differ in how they learn, how quickly they pick up and absorb information, how they comprehend the meanings of things etc. While meeting these diverse learning needs in a single classroom can be very challenging for a busy teacher, it must be done in order for all of the students to advance to the next level. I feel that it is important that a teacher be flexible with the methods by which he or she teaches students material. Adjusting the method from time to time gives learners who are having trouble with one presentation style the possibility of being able to make sense of the ideas being portrayed. Also it is important to alternate from individual lessons to group lessons to class lessons to allow for the diverse strengths and weaknesses of the students to be ac counted for.   Ã‚  Ã‚  Ã‚  Ã‚  In the particular classroom that I observe, the teacher does a good job of meeting the diverse needs of the students. Lesson by lesson, she alternates from doing hands on activities to verbally giving children the information. This allows for students with auditory strengths along with those students possessing visual strengths to get a chance to make sense of the material. She goes out of her way to make sure that every child’s way of learning is being a...

Hydroelectric Projects: Adverse Impacts and Mitigation Options 4 2. Land Area Flooded and People Displaced in Large Hydropower Projects iii 12 Acknowledgments Doug Mason (consultant) compiled data on more than twenty completed Latin American hydroelectric projects; this information was very useful in our analysis of environmental and social impacts, mitigation measures, and site selection criteria.Several current and former World Bank Group staff members provided useful comments and much encouragement, including Alessandro Palmieri, John Briscoe, Teresa Serra, Tony Whitten, Robert Goodland, Tor Ziegler, Warren Van Wicklin, William Partridge, Maria Clara Mejia, Kristine Ivarsdotter, Mateen Thobani, Salman Salman, and A.

Peter Brandriss helped edit and prepare the report for publication. iv ForewordFew types of development projects arouse as much controversy as hydroelectric dams. Their often serious environmental damage has been amply documented within the past decade. Nonetheless, many countries, in Latin America and worldwide, rely upon hydroelectric dams for a major portion of their electric power. Electricity remains a key ingredient for improving the lives of poor people almost everywhere. In developing countries, rapid urbanization and continued population growth will ensure increased demand for electric power for decades to come, even with the most successful of demand management and en ergy efficiency measures.Energy planners in many developing countries are thus likely to continue seeing hydroelectric dams as a promising source of renewable electric power. This report provides important advice for substantially reducing the environmental damage from future hydroelectric dams (whether or not they receive World Bank Group financing) through good project site selection. Although the report’s conclusions are drawn primarily from a review of Latin American dams, its innovative methodology for dam site selection–based on robust environmental and social criteria and straightforward, quantitative indicators–should prove useful worldwide.The report also helpfully summarizes the environmental mitigation options for the improved operation of existing hydroelectric dams. As such, this report should be of considerable interest to people interested in hydroelectric dams, whether at the World Bank, other multilateral and bilateral development institutions, government agencies, private energy companies, consulting firms, environmental and other NGOs, and academia. This report is part of the LCR Sustainable Development Working Paper Series published by the Latin America and the Caribbean Region’s Environmentally and Socially Sustainable Development Sector Management Unit (LCSES).This series seeks to disseminate the results of our analytical and operational work, present preliminary findings, and describe â€Å"best practices† with respect to major sustainable development issues facing the region. The findings, interpretations, and conclusions expressed in these papers are entirely those of the authors and should not be attributed to the World Bank, members of its Board of Executive Directors, or the countries they represent. John Redwood Director Environmentally and Socially Sustainable Development Latin America and Caribbean Region The World Bank v Executive SummaryLarge dams vary considerably in their adverse environment al and related social impacts. From an environmental standpoint, there are relatively good dams and bad dams. While some large dams are relatively benign, others have caused major environmental damage. The severity of environmental impacts from a hydroelectric project is largely determined by the dam site. While dams at good sites can be very defensible from an environmental standpoint, those proposed at bad sites will inherently be highly problematic, even if all feasible mitigation measures are properly implemented.This paper provides a simple, yet robust, methodology for comparing proposed hydroelectric project sites in terms of their expected negative environmental impacts, and relating these to power generation benefits. The paper also summarizes the environmental mitigation options for large dams. If properly implemented, these mitigation measures can effectively prevent, minimize, or compensate for many (though not all) of a hydroelectric project’s negative impacts.Non etheless, the most effective environmental mitigation measure is good site selection, to ensure that the proposed dam will cause relatively little damage in the first place. The paper presents quantitative indicators (using data that are relatively easy to obtain) for rating and ranking proposed new hydroelectric projects in terms of their likely adverse environmental impacts. Projects with a small reservoir surface area (relative to power generation) tend to be most desirable from both an environmental and social standpoint, in part because they minimize natural habitat losses as well as resettlement needs.In general, the most environmentally benign hydroelectric dam sites are on upper tributaries, while the most problematic ones are on the large main stems of rivers. Power expansion planning should ensure that environmental criteria, of the type outlined in this paper, are given appropriate weight in hydroelectric project site selection. Many of the more problematic dam sites are best left undeveloped, because the environmental or related social impacts are likely to be unacceptably high. In those cases, other power generation technologies are likely to be more environmentally desirable.Conversely, hydroelectric dams at good sites (with relatively low adverse impacts) and with effective implementation of proper mitigation measures are likely to be more attractive from an environmental standpoint than the most likely power generation alternatives. vii Introduction 1. Large hydroelectric dams are among the most controversial of all types of development projects. They have been the focus of much criticism of the World Bank and other international financing agencies. The â€Å"large dams† debate is often highly polarized.Critics of large hydroelectric projects point to a wide range of negative environmental and related social impacts, from the destruction of unique biodiversity to the displacement of vulnerable human populations. Defenders of large dams n ote that they are often the economically least-cost source of electric power available, especially to large urban centers; they are a renewable electricity source; and most other power generation technologies also imply significant adverse environmental impacts. 2.Worldwide, many countries rely upon hydropower for a substantial portion of their electricity. In developing countries, rapid urbanization and continued population growth will ensure increased demand for electric power for decades to come, even with the most successful of demand management and energy efficiency measures. Electricity remains a key ingredient for improving the lives of millions of poor people throughout the developing world. Energy planners in many countries are likely to continue seeing hydroelectric dams as a promising, renewable source of electricity.Major recent international initiatives–including the World Summit on Sustainable Development (Johannesburg, 2002), World Water Forum (Kyoto, 2003), Wo rld Commission on Dams (1997-2002), and the ongoing Dams and Development Project of the United Nations Environment Program–have reaffirmed the commitment of many governments and international agencies (including the World Bank) to hydropower development, but in a manner which fully reflects modern environmental concerns. 3. In this context, it is important to remember that all large hydroelectric dams are not alike.Large hydroelectric projects vary tremendously in the extent of their adverse environmental and related social impacts. (In this paper, we define large hydroelectric dams as those with 10 megawatts or more of installed generating capacity, to distinguish them from small or micro-dams which generate power on a smaller scale. ) For example, the 500–megawatt Pehuenche Hydroelectric Project in Chile flooded only about 400 hectares of land (with minimal damage to forest or wildlife resources) and has had no water quality problems.By contrast, the Brokopondo Dam i n Suriname inundated about 160,000 hectares of biologically valuable tropical rainforest and is known for serious water quality and aquatic weed problems, while providing relatively little electric generating capacity (only 30 megawatts). 4. We conducted a review of more than twenty completed hydroelectric dam projects in Latin America, along with several well-known projects from other regions. Our study found that some large dams are relatively benign, while others have caused substantial environmental and related social damage.This paper provides a methodology for easily comparing proposed hydroelectric project sites in terms of their expected adverse environmental impacts, relative to their power generation benefits. The technical criteria and quantitative indicators in this paper should be viewed as complementary to 1 2 LCR Sustainable Development Working Paper No. 16 the broader and often more process-oriented advice of other recent reports on dams, including the 2000 Dams and Development report of the World Commission on Dams.This paper’s recommendations are fully compatible with the World Bank’s Water Resources Sector Strategy, although this paper provides more technical detail regarding specific environmental impacts, mitigation options, and site selection criteria. Adverse Environmental Impacts of Hydropower Development 5. The range of adverse environmental and related social impacts that can result from hydroelectric dams is remarkably diverse. While some impacts occur only during construction, the most important impacts usually are due to the long-term existence and operation of the dam and reservoir.Other significant impacts can result from complementary civil works such as access roads, power transmission lines, and quarries and borrow pits. Table 1 summarizes the adverse environmental and social impacts associated with dams and reservoirs, along with the typical kinds of mitigation measures often proposed (and, less often, effective ly implemented). 6. Our analysis indicates that with properly implemented mitigation measures, many of the negative environmental and related social impacts of hydroelectric projects can be reduced to very acceptable levels.As outlined in Table 1, mitigation measures can effectively prevent, minimize, or compensate for most adverse impacts, but only if they are properly implemented. In our review of Latin American hydroprojects, we found wide variation in the extent to which environmental mitigation measures were planned, budgeted, and actually implemented. 7. Moreover, for some types of negative impacts, at some project sites, the available mitigation measures—even when properly implemented—are inherently unsatisfactory.Examples of adverse environmental impacts which occur at some hydroelectric projects and cannot be fully mitigated include (i) irreversible biodiversity loss, if critical natural habitats not occurring elsewhere are submerged (or left dry) by the dam; (ii) fish passage facilities frequently cannot restore the pre-dam ecological balance of a river, in terms of species composition or fish migrations; and (iii) some cultural property (including sacred sites) cannot be adequately salvaged prior to reservoir inundation. 8.Thus, because mitigation measures are often not fully implemented, and are sometimes inherently inadequate, the single most important environmental mitigation measure for a new hydroelectric project is good site selection, to ensure that the proposed dam is will be largely benign in the first place. In the following summary of typical adverse environmental impacts and corresponding mitigation options, it is important to keep in mind that all these types of impacts can be either avoided or minimized through good project site selection. 3 4Note: All of these impacts can be avoided or minimized by good dam site selection, the single most important environmental measure. Environmental Impacts Mitigation Options Impacts o f the Dam and Reservoir Flooding of Natural Habitats Some reservoirs permanently flood extensive natural habitats, with local and even global extinctions of animal and plant species. Very large hydroelectric reservoirs in the tropics are especially likely to cause species extinctions (although such losses are only infrequently documented due to the lack of scientific data).Particularly hard-hit are riverine forests and other riparian ecosystems, which naturally occur only along rivers and streams. From a biodiversity conservation standpoint, the terrestrial natural habitats lost to flooding are usually much more valuable than the aquatic habitats created by the reservoir. One occasional exception to this rule is that shallow reservoirs in dry zones can provide a permanent oasis, sometimes important for migratory waterfowl and other terrestrial and aquatic fauna.To offset the loss of natural habitats to reservoir flooding or other project components (such as borrow pits), one or more compensatory protected areas can be established and managed under the project. If an existing area is protected â€Å"on paper† only, a useful project option is to strengthen its onthe-ground protection and management. The area protected under the project should ideally be of comparable or greater size and ecological quality to the natural area lost to the project.Under the World Bank’s Natural Habitats Policy, hydroelectric and other projects should not be sited where they would cause the significant conversion or degradation of critical natural habitats that do not occur elsewhere (and, hence, cannot be adequately compensated). Loss of Terrestrial Wildlife The loss of terrestrial wildlife to drowning during reservoir filling is an inherent consequence of the flooding of terrestrial natural habitats, although often treated as a separate impact. Although they may be useful for public relations purposes, wildlife rescue efforts rarely succeed in restoring wild populati ons.Instead of drowning, the captured and relocated animals typically starve, are killed by competitors or predators, or fail to reproduce successfully, due to the limited carrying capacity of their new habitats. Wildlife rescue is most likely to be justified on conservation grounds if (a) the species rescued are globally threatened with extinction and (b) the relocation habitat is ecologically suitable and effectively protected. However, the money spent on rescue would usually do much more for wildlife conservation if it were invested in compensatory protected areas.The most effective way to minimize wildlife mortality in hydroelectric projects is to choose dam sites which minimize the wildlife habitat flooded. LCR Sustainable Development Working Paper No 16 Table 1. Hydroelectric Projects: Adverse Environmental Impacts and Mitigation Options Environmental Impacts Mitigation Options Involuntary Displacement Involuntary displacement of people is often the main adverse social impact of hydroelectric projects. It can also have important environmental implications, such as with the conversion of natural habitats to accommodate resettled rural populations.For physical displacement, the main mitigation measure is the resettlement of displaced populations, including new housing, replacement lands, and other material assistance, as needed. Success usually requires consultation and participatory decisionmaking by both the resettled and host populations (mandatory for World Bank–supported resettlement). Effective resettlement of vulnerable ethnic minorities is particularly challenging because some of these people are highly vulnerable to adverse social changes.Accordingly, the World Bank’s Involuntary Resettlement and Indigenous Peoples policies afford special consideration to these populations, specifying that, among other requirements, all viable alternative project designs should be explored before considering physical displacement for these groups. Fo r people who are not physically displaced but suffer an economic loss of livelihoods (based on fisheries, agricultural or grazing lands, river-edge clay for brick and tile production, or other resources), mitigation measures should involve the provision of replacement resources, new job training, or other income restoration assistance, as needed.Deterioration of Water Quality The damming of rivers can cause serious water quality deterioration, due to the reduced oxygenation and dilution of pollutants by relatively stagnant reservoirs (compared to fast-flowing rivers), flooding of biomass (especially forests) and resulting underwater decay, and/or reservoir stratification (where deeper lake waters lack oxygen).Water pollution control measures (such as sewage treatment plants or enforcement of industrial regulations) may be needed to improve reservoir water quality. Where poor water quality would result from the decay of flooded biomass, selective forest clearing within the impoundmen t area should be completed before reservoir filling. Downriver Hydrological Changes These adverse impacts can be minimized through careful management of water releases.Objectives to consider in optimizing water releases from the turbines and spillways include adequate downriver water supply for riparian ecosystems, reservoir and downriver fish survival, reservoir and downriver water quality, aquatic weed and disease vector control, irrigation and other human uses of water, downriver flood protection, recreation (such as whitewater boating), and, of course, power generation. From an ecological standpoint, the ideal water release pattern would usually closely mimic the natural flooding regime (although this may not be feasible for densely settled floodplains where flood protection is a high priority).Dams that generate baseload electricity are typically more capable of replicating near-natural downriver flows than those that produce peaking power (where daily water releases may fluctu ate sharply, often to the detriment of aquatic organisms that are adapted to less frequent flow changes). Environmental management plans for hydroelectric projects should specify environmental water releases, including for dams owned or operated by the private sector. Good Dams and Bad Dams 5Major downriver hydrological changes can destroy riparian ecosystems dependent on periodic natural flooding, exacerbate water pollution during lowflow periods, and increase saltwater intrusion near river mouths. Reduced sediment and nutrient loads downriver of dams can increase river-edge and coastal erosion and damage the biological and economic productivity of rivers and estuaries. Induced desiccation of rivers below dams (when the water is diverted to another portion of the river, or to a different river) kills fish and other fauna and flora dependent on the river; it can also damage agriculture and human water supplies.Mitigation Options Water-Related Diseases Some infectious diseases can sp read around hydroelectric reservoirs, particularly in warm climates and densely populated areas. Some diseases (such as malaria and schistosomiasis) are borne by water-dependent disease vectors (mosquitoes and aquatic snails); others (such as dysentery, cholera, and hepatitis A) are spread by contaminated water, which frequently becomes worse in stagnant reservoirs than it was in fast-flowing rivers.Corresponding public health measures should include preventive measures (such as awareness campaigns and window screens), monitoring of vectors and disease outbreaks, vector control, and clinical treatment of disease cases, as needed. Control of floating aquatic weeds (see below) near populated areas can reduce mosquito-borne disease risks. Fish and Other Aquatic Life Hydroelectric projects often have major effects on fish and other aquatic life. Reservoirs positively affect certain fish species (and fisheries) by ncreasing the area of available aquatic habitat. However, the net impacts are often negative because (a) the dam blocks upriver fish migrations, while downriver passage through turbines or over spillways is often unsuccessful; (b) many riveradapted fish and other aquatic species cannot survive in artificial lakes; (c) changes in downriver flow patterns adversely affect many species, and (d) water quality deterioration in or below reservoirs (usually low oxygen levels; sometimes gas super-saturation) kills fish and damages aquatic habitats.Freshwater molluscs, crustaceans, and other benthic organisms are even more sensitive to these changes than most fish species, due to their limited mobility. Management of water releases may be needed for the survival of certain fish species, in and below the reservoir. Fish passage facilities (fish ladders, elevators, or trap-and-truck operations) are intended to help migratory fish move upriver past a dam; they are usually of limited effectiveness for various reasons (including the difficulty of ensuring safe downriver passage for many adults and fry).Fish hatcheries can be useful for maintaining populations of native species which can survive but not successfully reproduce within the reservoir. They are also often used for stocking the reservoir with economically desired species, although introducing non-native fish is often devastating to native species and not ecologically desirable. Fishing regulation is often essential to maintain viable populations of commercially valuable species, especially in the waters immediately below a dam where migratory fish species concentrate in high numbers and are unnaturally easy to catch.Floating Aquatic Vegetation Floating aquatic vegetation can rapidly proliferate in eutrophic reservoirs, causing problems such as (a) degraded habitat for most species of fish and other aquatic life, (b) improved breeding grounds for mosquitoes and other nuisance species and disease vectors, (c) impeded navigation and swimming, (d) clogging of electro-mechanical equipment at dams, and (e) increased water loss from some reservoirs. Pollution control and pre-impoundment selective forest clearing will make reservoirs less conducive to aquatic weed growth.Physical removal or containment of floating aquatic weeds is effective but imposes a high and recurrent expense for large reservoirs. Where compatible with other objectives (power generation, fish survival, etc. ), occasional drawdown of reservoir water levels may be used to kill aquatic weeds. Chemical poisoning of weeds or related insect pests requires much environmental caution and is usually best avoided. LCR Sustainable Development Working Paper No 16 Environmental Impacts (table continues on following page) 6 Table 1.Hydroelectric Projects: Adverse Environmental Impacts and Mitigation Options (continued) Environmental Impacts Mitigation Options Loss of Cultural Property Cultural property, including archaeological, historical, paleontological, and religious sites and objects, can be inundated by reser voirs or destroyed by associated quarries, borrow pits, roads, or other works. Structures and objects of cultural interest should undergo salvage wherever feasible through scientific inventory, careful physical relocation, and documentation and storage in museums or other appropriate facilities.However, it is often not possible to replace the loss of, or damage to, unique or sacred sites which may have great religious or ceremonial significance to indigenous or other local people. Reservoir Sedimentation Over time, live storage and power generation are reduced by reservoir sedimentation, such that much of some projects’ hydroelectric energy might not be renewable over the long term. If effectively implemented, watershed management can minimize sedimentation and extend a reservoir’s useful physical life, through the control of road construction, mining, agriculture, and other land use in the upper catchment area.Protected areas are sometimes established in upper catchme nts to reduce sediment flows into reservoirs, as with the Fortuna Dam in Panama and the proposed Rio Amoya (Colombia) and Nam Theun II (Laos) projects. Aside from watershed management, other sediment management techniques for hydroelectric reservoirs may at times be physically and economically feasible; they include, among others, upstream check structures, protecting dam outlets, reservoir flushing, mechanical removal, and increasing the dam’s height.Greenhouse Gases Greenhouse gas releases from reservoirs can be reduced by a thorough salvage of commercial timber and fuelwood, although frequently this does not happen because of (a) high extraction and transportation costs, (b) marketing constraints, or (c) political and economic pressures not to delay reservoir filling. The surest way to minimize greenhouse gas releases from reservoirs is to choose dam sites that minimize the flooding of land in general, and forests in particular. table continues on following page) Good Dams and Bad Dams 7 Greenhouse gases (carbon dioxide and methane) are released into the atmosphere from reservoirs that flood forests and other biomass, either slowly (as flooded organic matter decomposes) or rapidly (if the forest is cut and burned before reservoir filling). Greenhouse gases are widely considered to be the main cause of human-induced global climate change. Many hydroelectric reservoirs flood relatively little forest or other biomass.Moreover, most hydroprojects generate sufficient electricity to more than offset the greenhouse gases which would otherwise have been produced by burning fossil fuels (natural gas, fuel oil, or coal) in power plants. However, some projects which flood extensive forest areas, such as the Balbina Dam in Amazonian Brazil, appear to emit greenhouse gases in greater amounts than would be produced by burning natural gas for many years of comparable electricity generation. Mitigation Options Impacts of Complementary Civil Works Access RoadsNew acc ess roads to hydroelectric dams can induce major land use changes— particularly deforestation—with resulting loss of biodiversity, accelerated erosion, and other environmental problems. In some projects (such as Arun II in Nepal), the environmental impacts of access roads can greatly exceed those of the reservoir. The siting of any new access roads should be in the environmentally and socially least damaging corridors. Forests and other environmentally sensitive areas along the chosen road corridor should receive legal and on-the-ground protection.Road engineering should ensure proper drainage, to protect waterways and minimize erosion. Environmental rules for contractors (including penalties for noncompliance) should cover construction camp siting, gravel extraction, waste disposal, avoiding water pollution, worker behavior (such as no hunting), and other construction practices. See Ledec and Posas (2003) for details. Power Transmission Lines Power transmission line r ights-of-way often reduce and fragment forests; indirectly, they occasionally facilitate further deforestation by improving physical access.Large birds are sometimes killed in collisions with power lines, or by electrocution. Power lines can also be aesthetically objectionable. Power lines should be sited to minimize these concerns and built using good environmental practices (as with roads). In areas with concentrations of vulnerable bird species, the top (grounding) wire should be made more visible with plastic devices. Electrocution (mainly of large birds of prey) should be avoided through bird-friendly tower design and proper spacing of conducting wires.Quarries and Borrow Pits Quarries and borrow pits are used to provide material for construction of the dam and complementary works. They can considerably increase the area of natural habitats or agricultural lands that are lost to a hydroelectric project. To the greatest extent feasible, quarries and borrow pits should be sited w ithin the future inundation zone. Where this is not feasible, the pits should be rehabilitated after use, ideally for conservation purposes such as wetland habitats. Impacts of Induced DevelopmentAssociated Development Projects Hydroelectric dams often make possible new development projects with major environmental impacts, including irrigation, urban expansion, and industrial facilities (due to new water supplies). New development projects should be planned to minimize adverse environmental and social impacts. Environmental impact assessment studies should be carried out in the early stages of project planning; the resulting environmental mitigation plans should be fully implemented. Additional DamsThe construction of the first dam on a river can make the subsequent construction of additional dams more economical, because flow regulation by the upriver dam can enhance power generation at the downriver dam(s). The environmental impact assessment study for the first dam on any river should include a cumulative environmental assessment of the likely impacts of proposed additional dams on the same river system. Implementation of mitigation measures for cumulative (rather than dam-specific) impacts should be completed or well underway prior to construction of the second dam on the river. LCR Sustainable Development Working Paper No 16Environmental Impacts 8 Table 1. Hydroelectric Projects: Adverse Environmental Impacts and Mitigation Options (continued) Key Indicators of Likely Environmental Impacts 9. Before a dam site is chosen (with a project-specific environmental impact assessment), sector-level environmental analysis can rank potential sites according to their degree of environmental desirability. A sectoral environmental assessment (SEA) should be carried out prior to making major power sector planning decisions, especially in the comparison of hydroelectric and other power generation (and demand management) alternatives.However, even without a detailed SEA , it is possible to carry out a simple environmental and ranking of different hydropower sites using basic, often readily available technical data. There exist various quantitative, easily calculated indicators that can be used to estimate the extent of adverse environmental impacts for any proposed hydroelectric project. 10. This paper presents 13 quantitative, easily calculated indicators that we consider especially useful for hydroproject site selection from an environmental standpoint. These indicators have high predictive value for likely adverse environmental (and related social) impacts.The first nine indicators (A–I) use information that is normally easy to obtain from basic dam planning data, even without a separate environmental study. The other four indicators (J–M) are also very important in the environmental comparison of alternative dam sites, but involve data that may require further environmental (or resettlement) study to obtain. Indicator A (hectares of land inundated) is perhaps the single most useful one in predicting the degree of environmental damage, because this indicator is positively correlated with many of the others.From a social standpoint, the number of people requiring resettlement (Indicator J) is an especially important. A. Reservoir Surface Area 11. The area flooded by the reservoir is a strong proxy variable for many environmental and social impacts (Goodland, 1997). A large reservoir area implies the loss of much natural habitat and wildlife and/or the displacement of many people. Very large reservoirs are typically in the lowlands (often with tropical disease and aquatic weed problems) and usually impound larger rivers (with more fish and other aquatic species at risk).A very useful measure of environmental costs relative to economic benefits is the ratio of inundated hectares per megawatt (ha/MW) of electricity; it varies by four orders of magnitude for large power projects (see Table 2). The global average f or all large hydroelectric dams constructed to date (not just those in Table 2) is about 60 ha/MW (J. Goldemberg, pers. comm. ); it would be environmentally highly desirable for this average to be much reduced in future hydroprojects. B. Water Retention Time in Reservoir 12.Mean water retention time during normal operation (the shorter, the better) is very useful in estimating the extent to which reservoirs will have long-term water quality problems. This figure (number of days) is calculated as a function of reservoir volume (cubic meters) and mean river flow (cubic liters per second). 9 10 LCR Sustainable Development Working Paper No. 16 C. Biomass Flooded 13. Biomass flooded is calculated in tons per hectare based on the percent cover of different vegetation types in the reservoir area.For good reservoir water quality, dams should minimize flooding of forests (which have high biomass content). Flooding native forests also threatens biodiversity and releases greenhouse gases. D. L ength of River Impounded 14. To conserve aquatic and riparian biodiversity (including riverine forests), dam sites should minimize the length (kilometers) of river (main stem plus tributaries) impounded by the reservoir (measured during high flow periods). E. Length of River Left Dry 15. This measures the kilometers of river left dry (with less than 50 percent of dry season mean flow) below the dam, due to water diversion.The length of dried-up river bed (before the next important downstream tributary) should be minimized, due to the loss of fish and other aquatic life, damage to riparian ecosystems, and disruption of human water supplies, agriculture, and/or fishing. F. Number of Downriver Tributaries 16. The more (major, undammed) tributaries downriver of the dam site, the better, in terms of maintaining accessible habitat for migratory fish, the natural flooding regime for riverine ecosystems, and nutrient or sediment inputs needed for the high biological productivity of estuarie s. G. Likelihood of Reservoir Stratification 7. Stratification in a reservoir occurs when the lake’s upper zone (epilimnion) is thermally divided from the deeper zone (hypolimnion); the latter becomes stagnant and lacking in dissolved oxygen (anaerobic), thereby unsuitable for most aquatic life. A rapid estimate of stratification tendencies in a reservoir can be obtained with the Densimetric Froude Number (F). F can be calculated as: F = 320(L/D)(Q/V), where L = length of the reservoir (meters), D = mean reservoir depth (meters) (for which dam height can be a proxy), Q = mean water inflow (cubic meters per second), and V = eservoir volume (cubic meters). If F is less than 1, some stratification is expected, the severity of which increases with a smaller F. When F is greater than 1, stratification is not likely. H. Useful Reservoir Life 18. Useful reservoir life is the expected number of years before a reservoir’s dead storage is completely filled, so that further sedim entation reduces the live storage and curtails power generation. Dead storage comprises all reservoir water beneath the level of the intakes for the dam’s turbines; all of the water at or above this intake level is part of the live storage.Useful reservoir life is a function of dead storage and river-borne sediment loads. Useful reservoir life is a good indicator of the relative sustainability of electric power generation; it varies from less than ten years before dead storage is filled (such as the Paute Dam in Ecuador) to potentially thousands of years. In general, reservoirs with the longest useful life are relatively deep and situated on rivers with low sediment loads. Maintaining low sediment loads over time typically requires good watershed management. Good Dams and Bad Dams 11 I. Access Roads through Forests 19.Where the risks of induced deforestation are high, project siting should minimize the kilometers of required new or upgraded access roads passing through or nea r natural forests. J. Persons Requiring Resettlement 20. The number of people physically displaced by hydroelectric projects ranges from zero (e. g. Pehuenche, Chile) to over 50,000 in Latin America (e. g. Yacyreta, Argentina-Paraguay) and well over 1 million in Asia (Three Gorges, China). Dam siting should generally seek to minimize the number of individuals or households requiring resettlement from lands affected by the reservoir and complementary civil works.A useful measure for relating resettlement costs to hydropower benefits is the ratio of people displaced per megawatt (Table 2). Because of their usually greater vulnerability to social disruption, it is especially important to minimize the number of indigenous people with traditional land-based models of production who would require resettlement. K. Critical Natural Habitats Affected 21. It is important to know the number of sites and hectares of critical natural habitats that would be lost to inundation, borrow pits, or oth er project components.Critical natural habitats include existing and officially proposed protected areas, as well as unprotected areas of known high importance for biodiversity conservation. To comply with the World Bank’s Natural Habitats Policy, hydroelectric projects should not cause any significant loss or degradation of critical natural habitats. On the other hand, some hydroelectric projects imply very important conservation opportunities by providing a strong justification (sediment reduction) and financial resources needed for protecting natural habitats in upper catchment areas.L. Fish Species Diversity and Endemism 22. Fish species diversity is the number of species known from the project area, including the dam and reservoir site, as well as the downstream zone of project influence. Fish species endemism is the number of native species known only from the project area, or the river system where the project is located, and nowhere else on Earth. Dams are environment ally less objectionable if they affect rivers with a naturally low diversity and endemism of native fish species.In general, large, lowland rivers in warm (tropical or subtropical) climates have a high diversity of native fish and other aquatic organisms, while small rivers in cold (tropical highland or temperate) climates have relatively low diversity. Large, lowland rivers are also more likely to have significant seasonal fish migrations, which are effectively blocked by most dams. However, highland rivers and streams often have relatively high endemism in their fish fauna, especially if they are isolated from other rivers by waterfalls or other natural barriers.River segments with threatened fish species found nowhere else should be classified as critical natural habitats and, ideally, would receive permanent protection from dams or other potentially damaging civil works. However, dams and reservoirs in upper tributary rivers and streams need not threaten the survival of any ende mic fish (or mollusks, or other aquatic life) if they affect only an insignificant portion of the river area used by these species (see Indicators D and E); they should also be sited so as not to block important fish migrations. M. Cultural Property Affected 23.An indication of the cultural significance of the area to be inundated (or otherwise affected by the project) is the number (by type) of cultural (archaeological, historical, paleontological, or religious) objects or sites. It is important to note whether each type of cultural property at the project site is salvageable (totally, partially, or not at all). 12 LCR Sustainable Development Working Paper No. 16 Table 2.

Malaria Issue Report

The issue I am going to be talking about in my report is about how to prevent the transmission of malaria around the world. Malaria is a mosquito-borne, climate sensitive disease caused by the parasite Plasmodium.[1] Malaria is caused by one of four species of the protoctist Plasmodium[2]. The Plasmodium parasites multiply in red blood cells; this can cause symptoms such as fever and headache, but in severe cases the disease can lead to death. Transmission Malaria is transmitted through the bite of an infected female (Anopheles) mosquito; although it can be transmitted through contact of infected blood but this is very uncommon.[3] The cycle of malaria is an Anopheles mosquito bites an infected person; a small amount of infected blood is taken. The plasmodium parasite grows and matures in the mosquito's gut for approximately a week before it then travels to the mosquito's salivary glands. When the mosquito next bites someone, these parasites mix with the saliva, are then injected with the bite, and the transmission of malaria is complete.[4] Cycle in the Body Once in the blood, the parasites travel to the liver and enter liver cells, to grow and multiply. After some time, the parasites leave the liver cells and enter red blood cells. In the red blood cells the malaria parasites continues to grow and multiply. After they mature, the infected red blood cells rupture, freeing the parasites to attack and enter other red blood cells.[5] Symptoms Toxins released when the red cells burst, these are what cause the common symptoms of malaria, these are: 1. Fever 2. Chills 3. Flu like symptoms Statistics According to the World Health Organisation (WHO) malaria report 2011, there were 216 million cases of malaria and an estimated 655,000 deaths in 2010. Malaria mortality rates have fallen by more than 25% globally since 2000. Most deaths occur amongst children living in Africa where a child dies every minute of malaria and the disease accounts for approximately 22% of all childhood deaths.[6] Malaria is a disease that only occurs in certain climates, due to the fact that malaria is passed on through mosquito bites so only certain countries and regions have the conditions that mosquitos can survive in are affected by the disease; this includes sub-Saharan Africa, Asia and Latin America as shown in the picture below: [7] This picture shows that malaria affects countries mainly in the Southern Hemisphere, especially South America (but north of Argentina) Sub-Saharan Africa and Southern Asia. Malaria has been on the rise since the 1970s and constitutes a serious risk to health in many tropical countries.[8] The Problem with malaria is that it mainly affects people who live in LEDCs (Less Economically Developed Countries) the problem with this is that they cannot afford to get the healthcare to treat the disease unlike with MEDCs (More Economically Developed Countries) where they don’t get diseases of this kind commonly but are able to afford the healthcare. Malaria also causes a number of deaths and illnesses every year, especially in countries which suffer from a lot of poverty. This means that if parents catch the diseases then their children will be orphaned and left to fend for themselves. Solutions to the Problem There are several methods of treating malaria and these are some of the best methods to protect us from the disease: Nets A mosquito net protects against mosquitos, flies, and other airborne insects. Mosquito nets are the first line of defence against the deadly bite of mosquitos. The fine, see-through mesh stops insects from biting or affecting the person using the net. The mesh is fine enough to stop these insects entering the sleeping area of the person. Research has found that the latest Long Lasting Insecticidal Nets (LLINs) save lives; they have been proven to cut malaria cases in children by half as well as reducing child deaths by 20%[9]. The use of these nets can also help protect other people sleeping nearby who are not sleeping under a net. It’s estimated that when 80% of people sleep under a net, the entire community is protected.[10] Although it is vital that the people using the mosquito nets regularly check the nets for any holes big enough for insects to get through. Scientists in Senegal have been researching the success rate of mosquito nets after six million nets were distributed over five years. Within three weeks of the nets being introduced, the scientists found that the number of malaria attacks had started to fall – it had fell by 13 times since before the nets had come in. The researchers also collected specimens of Anopheles gambiae, which is the type of mosquito species responsible for transmitting malaria to humans in Africa. Between 2007 and 2010 the proportion of the insects with a genetic resistance rose from 8% to 48%. By 2010 the proportion of mosquitoes resistant to Deltamethrin was 37%.[11] Testing Malaria parasites in the blood can best be detected under a microscope, but, when this is not available malaria cases can also be quickly and accurately identified using a Rapid Diagnostic Test (RDT). RDTs are disposable blood testing kits which can be used anywhere and provide a quick result, they measure the amount of plasmodium in the blood; therefore showing if you have malaria or not. RDTs mean that a potentially life-saving diagnosis of malaria, which usually could only be possible in hospitals, can now be made available anywhere.[12] The reliability of RDTs is a successful diagnostic reading of 80% or in other words; 4 out of 5 people tested for malaria get a correct result back.[13] Implications of the solutions to the problem There are a number of solutions to malaria, although they do have economic and environmental implications. The solutions include: Nets The economic problem with nets is that malaria is mainly affecting LEDCs; therefore people are unable to afford the cost of buying drugs nets as they can be expensive. Environmental issues with mosquito nets are that mosquitos are possibly starting to get immune to the chemical Deltamethrin which is used in the bed nets; this means that they are no longer being useful by stopping the female mosquito from biting and killing harmless insects instead. The social implications of using nets are that nets prevent people being bitten by malaria carrying mosquitos, this means that less access to health services are needed; therefore less time is lost from work because of malaria. Medicines Artemisinin-based Combination Therapies (ACTs) are therapies made by combining an extract of the Artemisia plant and another medicine. They are the most effective and advance treatments for malaria, and are strongly recommended for the treatment of malaria in Africa.[14] The implication to this method is that they are highly expensive to produce and take around 15 years to research and develop. And seeing as malaria mainly affects LEDCs it wouldn’t be much use to them, as they will not be able to afford to buy them. Also the problem with using drugs is that a lot of testing takes place on animals which have ethical implications along with it. Benefits/Risks of solutions to the Problem Medicines In the table below there is a list of advantages and disadvantages for using different medicines for treating malaria: Chemoprophylaxis drug Presentation Advantages Disadvantages Proguanil Paludrine tablets 1. Low cost 2. Well tolerated 3. Suitable for pregnant or breastfeeding women 1. Increasing resistance of P. falciparum to chloroquine 2. Large number of tablets required if taken in combination Chloroquine Nivaquine syrup Avloclor tablets 1. Mefloquine Lariam tablets 1. Weekly dose 2. Effective for most areas of the world 3. Can be used in the last 2 trimesters of pregnancy 1. Needs to be commenced 2 to 3 weeks prior to departure 2. May cause neuro-psychiatric adverse events Doxycycline Capsule 1. Low cost 2. Generally well tolerated 3. Can be commenced close to departure date 1. May cause photosensitivity 2. May cause vaginal yeast infections in women 3. Unsuitable for children under 12 years Atovaquone/proguanil Malarone tablets 1. Well tolerated 2. Can be commenced close to departure date 3. Short course 1. Expensive [15] According to the table above the advantages outweigh the disadvantages in the five different medicines, although with Doxycycline the advantages and disadvantages are in the same proportion. This would suggest that Doxycycline may not as effective anti-malarial medicine as some of the others. Testing Another solution to the problem could be to use malaria testing kits such as the Rapid Diagnostic Tests (RDT). The benefit of this is that it can create a diagnosis in fraction of the time that a standard test takes. This means that people who have malaria can be treated a lot quicker than they usually could be by the standard method, which involves looking at a blood sample under a microscope to detect plasmodium. An issue with RDTs is that they can be expensive for people living in LEDCs as they can range from $1.20 – $13.50 per test.[16] The risks of RDT is that, although it is a quick test, it is not always effective at identify the plasmodium in the blood. The danger is that you may get inaccurate result, leading to you being quite unaware of having the disease, therefore getting the treatment early enough to take effect. Alternative Solutions to the Problem Quinine Another solution to the problem which was used up until the 1930s as the only cure for malaria is quinine. It is found in the Andes Mountain range of Peru and Ecuador[17]. The medicinal properties to quinine has been around since the 17th century, but back then people used to chew the bark off of the cinchona tree as it was believed to be a useful treatment for malaria. Although people didn’t have medicinal knowledge, due to the positive result, they thought it was an effective method of malaria treatment. The active ingredient is quinine which is found in the cinchona tree. Quinine works by lowering the body’s core temperature, thereby killing the plasmodium parasites that cause malaria in the red blood cells. Quinine can also be found in tonic water; some doctors/ GPs may recommend drinking tonic water when going to a high risk country. Vaccine A vaccination involves injecting a small harmless amount of infection into you. Finding a vaccine to protect people from malaria would be the best possible defence[18]. Around the world scientists are working on this important research.[19] However, malaria parasite, plasmodium has proven to be adapting to the different cures and vaccines that scientists have been creating. This means that they change their characteristics as antibodies are developed. This adaptability has made finding a vaccine especially challenging.[20] Currently there is no vaccine, but there are several being developed. Several potential malaria vaccines are already being tested in clinical trials; although no vaccine has been licensed for use.[21] It will be a long wait before a vaccine is available to prevent the spread of malaria.[22] Dr Sandy Douglas (Welcome Trust Clinical Research Training) at the University of Oxford said â€Å"We have found a way of making antibodies that kill all different strains of malaria parasites. This is still in an early research phase; the next step is to do clinical trials in people.†[23]
