Biodiversity can sometimes only be preserved if natural habitats are excluded from human uses. Such protection measures generate positive externalities at the global scale. This holds especially for protection in developing countries that host great parts of global biodiversity. For...

Agriculture and forestry play an important role in emitting and storing greenhouse gases. For an efficient and cost-effective climate policy it is therefore important to explicitly include land use, land use change, and forestry (LULUCF) in economy-climate models. This paper gives an overview...

Climate change affects the physical and biological system in many regions of the world. The extent to which human systems will suffer economically from climate change depends on the adaptive capabilities within a region as well as across regions. We use an economic General-Equilibrium model and...

Since naturally occurring genetic information serves as a valuable input for biotechnological R&D, the private provision of genetic resources could generate income for the protection of biodiversity-rich areas. However, there has been a controversy over whether these potential revenues are...

Global climate change presents long-term risks to agriculture. In general, global climate change is expected to positively affect Russian agriculture. In high and middle latitudes, global warming would expand the growing season. Acreages of agricultural crops may expand toward the north,...

Ex-ante regulations and ex-post liabilities for using a new technology will induce additional costs for adopters. The standard model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible cost reductions. The case analysed is...

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...

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...

There is no doubt that an improved hazardous waste management in mining and mineral processing will reduce environmental and health risks in South Africa. However, skeptics fear that waste reduction, appropriate treatment and disposal are not affordable within the current economic circumstances,...

The paper discusses the decisions on the reform of the CAP from June 2003. The decisions focus on the decoupling of the direct payments to farmers from production. This will reduce production incentives and thereby improve the allocation of resources. However, payments to farmers will hardly be...
