Discuss the different influences of climatic inputs on soil fertility and vegetation productivity in the tropical rainforest ecosystem. Explain the importance of maintaining floral diversity in the system and suggest ways to reduce the rate of biodiversity loss. 02#4 Explain why the more developed countries are blamed for the vanishing of tropical rainforests. Assess the global problems caused by forest destruction. Discuss how the governments in these rainforest regions can achieve a balance between economic growth and forest conservation. Illustrate your answer with examples. 88 P.2 01#4 Sustainability is the ability of a system to support for a long period the livelihood of the people. With reference to specific examples, describe how the native people living in tropical rainforests maintain a sustainable livelihood and explain why their livelihood may be disrupted. Discuss how this sustainable system can be maintained for a long period. 00#4 Biodiversity in tropical rainforests is under stress. The way that people define resources may influence the biodiversity loss in tropical rainforests. What is biodiversity ? Why is it important to maintain biodiversity ? In what ways do the differences in the definition of resources between developers and environmentalists affect the development of biodiversity in tropical rainforests ? Suggest ways to slow down biodiversity loss. 97#4 Sustainable land uses are those that are capable of maintaining yields for a long time without causing much environmental degradation. With reference to specific examples, describe the operation of shifting cultivation. Explain how it could be a sustainable land use in the tropical rainforest landscape. Discuss the suggestion of conserving rainforests by making them national parks. P.3 96#2 Different points of view and self-interest play an important role in shaping the distribution of the tropical rain forest. Explain why the tropical rain forest has been cleared in many less developed countries during recent decades. Why are many environmental groups concerned about its loss and conversion ? Illustrate your answer with examples. 95#4 ‘Although the tropical rain forest is a region with many constraints on development, it has bee greatly exploited by human beings in the past decades.’ Explain why the tropical rain forests have been rapidly exploited in the past decades and identify the problems that have hindered their economic development. Evaluate the solutions which have been suggested to remedy these problems. Illustrate your answer with reference to a case study. 94#4 ‘Survival and profit making are the basic causes for upsetting the traditional harmonious man-environment relationship found in the tropical rain forest landscape.’ With reference to different types of human activities found in the tropical rain forest landscape, comment on the validity of the statement. 88#3 “ In terms of the amount of biomass, natural vegetation is very luxuriant in tropical rain forests, but the natural conditions for developing farming in tropical rain forests are not so favourable.” Explain this statement. With reference to a tropical rain forest area of your choice, evaluate the impact on the natural ecosystem of any one attempt to develop agricultural in that area.

Most of these activities are related to two factors: poverty and inappropriate use of technology. Explain how poverty and inappropriate use of technology have contributed to desertification in the semi-arid rural areas. With reference to an appropriate, discuss the impact of climatic change in recent decades on desertification. 99#3 Describe and explain how human beings make use of environmental resources in tropical deserts. Discuss the positive impacts of the development on the local landscape and people. Support your answer with appropriate examples. P.5 98#4 Desertification is the result of human over-exploitation of the land rather than a change of climate. Explain the above statement with reference to a specific region. Evaluate the effectiveness of the remedial measures adopted in arresting the process of desertification. 93#4 Describe the hydrologic cycle in a tropical desert region. By means of examples assess the impact of the various components of the cycle upon the human use of this environment. 91#4 Desertification is principally caused by the disturbance of equilibrium in the desert-margin ecosystems. Explain how the degradational processes of desertification can be arrested. 90#4 Man is constrained by the environment in some places but, in other places, or at other times, man is a major factor in altering the environment. With reference to places within the tropical desert environment, explain why this occurs. What are the conditions which may lead to a change in direction of the relationship between man and the environment ? 89#4 Describe and explain the extent to which similarities and differences of man-environment relationships occur between tropical desert and tundra areas. Illustrate your answer with reference to case studies chosen from these two environments.
