How does deforestation in tropical rainforest regions affect different stakeholders? 1. Role Play: Many green organizations oppose tree-cutting in tropical rainforest because this will greatly affect the atmosphere, biosphere and lithosphere at both local and global scales. However, cutting of trees for various human activities has different meanings to different stakeholders. Through this role play, you can understand that deforestation and its relevant economic activities are beneficial to some stakeholders (i.e. positive impact) but detrimental to others (i.e. negative impact). a) Understand the standpoints of various stakeholders below. We want to keep our lifestyles! The forests are our valuable assets. They belong to us. Large scale cutting of trees for various commercial activities will destroy our homes. Deforestation also causes serious soil erosion which greatly affect our harvests from shifting agriculture. Native people in tropical rainforests Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? 53 We can find 90% of primates, 80% of insects and more than 150 thousand known plant species in the tropical rainforests. Massive deforestation in rainforest regions causes great damage to the ecosystem. Deforestation also affects the amount of carbon dioxide and oxygen in our atmosphere. We believe that such massive deforestation is an important cause of enhanced greenhouse effect and global warming. Environmentalists We support the development of the rainforests for various commercial purposes, such as commercial logging and plantation agriculture. They provide jobs to us. You know… without money, we cannot improve our living standard.

We also provide jobs for the inhabitants of the tropical rainforests and improve their living The manager of a commercial standard. logging company Our country has a heavy foreign debt burden. Different types of commercial activities at tropical rainforests bring us lots of benefits. We need these for the development of our country. However, the forests are our valuable assets. Different stakeholders in my country have The governor of a country different opinions on conserving the forests. What with tropical rainforests should I do? Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? 54 Stop destroying the tropical rainforests! More than 2,000 anticarcinogenic plants can only be found in the tropical rainforests. Cures for AIDS are likely to be found in some rainforest plants. An expert on treating AIDS We live in coastal cities in different parts of the world. Massive deforestation in tropical rainforest regions causes global warming which greatly affects our living environment, e.g. climate and sea level. Polar ice caps are melting and coastal flooding will be more common. Besides, deforestation affects the world’s supply of oxygen because more than 20% of the world’s oxygen is produced by People in other the Amazon Rainforest alone. parts of the world b) Collect more information about the impact of deforestation and explain why different people have different views on massive deforestation in tropical rainforest regions. Jot down your points in Table 9. Role Standpoints Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? Role 55 Standpoints Table 9 c) Divide yourselves into several groups, each performing one of the above roles. Conduct a role play about the impact of deforestation and try to reach an agreement on massive deforestation in tropical rainforest. Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? d) 56 After the role play, summarise your views about the impact of deforestation at tropical rainforest regions in about 100 words below. Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? 57 A. What can be done to prevent the disappearance of tropical rainforests? 1. a) The following are possible ways of protecting tropical rainforests. In order to protect the tropical rainforests, commercial logging activities should be regulated and tropical timber trade should be controlled. Afforestation should be carried out. Moreover, national parks and nature reserves should be set up within the rainforest areas for conservation purposes. By conserving the rainforests in these ways, no development is allowed in the parks or reserves. The natural habitats and indigenous peoples in the tropical rainforests can then be preserved. b) Browse the Internet or find relevant information from the library about the details of these measures to complete Table 10. Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? Measure 58 Details Afforestation Controlling various commercial activities, such as commercial logging Setting up national parks and nature reserves Table 10 Measures for protecting the tropical rainforests c) After completing Table 10, you will note that most of the measures are at national level. As a student, what can be done to save the tropical rainforests? Give your suggestions in the space provided below.

Justify your choice. Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? 62 B. Is ‘sustainable development of tropical rainforests’ a possible way out? Definition Sustainable tourism development is a kind of tourism which ecosystems by aims at making conserving low impact the on local the environment and local culture on one hand. On the other hand, income can be generated (including those for the local people) and employment can be created. 1. Study the following case study about the development of tropical rainforests. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Peru is a country located at the north-western coast of South America. It includes some famous geographical features, such as the Amazon Basin and the Andes Mountain. The rainforests cover a large area of the north-eastern part of Peru. Just like the tropical rainforests in other parts of the world, deforestation of the Peruvian rainforests was also once a great problem. Commercial logging, as well asCommercial many other human activities, was carried out in the rainforests. Trees were cut down extensively and timber was sold to oversea markets for huge profits. Disappearing Green Canopy—Who should pay for the massive deforestation in rainforest regions? 63 However, these short-term benefits seriously destruct the rainforests which are valuable assets of a less developed country like Peru. The rainforests should be protected and used reasonably so that long-term socio-economic benefits can be generated. Therefore, the Peruvian government decided to establish some national parks and reserves in its rainforest regions. The Reserva Nacional Tambopata-Candama (established in 1990) is an example of this. It covers an area of about 1.5 million hectares and is the habitat for many different species of plants, birds. mammals, reptiles and fish. The natural environment and the lifestyles of local people in the Reserva Nacional Tambopata-Candama are then well protected on one hand. On the other hand, carefully planned tourism activities are still allowed in the protected area so that extra income can be generated for both the local people and the government. This kind of tourism allows small groups of tourists staying in the lodges of rainforests. Different kinds of activities may be carried out, such as hiking, learning about the traditional lifestyles of the native people, fishing and visiting local, traditional farms. Local people in the rainforests are engaged by running the lodges and local Peruvians are the tour guides. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Further references about the Peruvian tropical rainforest and sustainable tourism development: Newman, R.
