Protecting Brazil's tropical forest: a CGE analysis of macroeconomic, sectoral, and regional policies

The 'deforestation problem' in Brazil consists of a variety of interrelated issues, of which this paper identifies a regional, sectoral and macroeconomic dimension. Using a regionally and sectorally disaggregated general equilibrium model of Brazil, it is shown that macroeconomic reform is complementary to conservation policies. Therefore, if not for other reasons, macroeconomic reform is urgently needed to provide an adequate framework for microeconomic conservation policies to be effective. The analysis also shows that regional land taxes in the Amazon outperform the reduction of fiscal incentives for agriculture, both with regards to ecological effectiveness and efficiency. Finally, the results do not support claims for compensation payments.deforestation,public policy,general equilibrium analysis,Brazil

National and international policies for tropical rain forest conservation: a quantitative analysis for Cameroon

This paper provides a numerical general equilibrium assessment of policies to reduce tropical deforestation in Cameroon. Market failure - mainly in the form of national and international externalities - and policy failures - such as highly distorted product markets - are identified as major sources of overexploitation. The ecological effects of deforestation control are shown to depend crucially upon its impact on land use patterns whereas its efficiency effects hinge on the manner in which a specified set-aside target is achieved. If the international community wants to ensure a higher level of protection of these forests, and to do so within a market-based system, the provision of conditional financial resources is necessary.
