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 '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...

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...

We consider a model where a given number of firms decide on a pollution-reducing production technology, and then hire workers who subsequently form a monopoly union which sets the wage. We study the possibility of "double dividents", i.e. simultaneous reduction in pollution and increases in...

In order to reach a Pareto optimal outcome with transboundary environmental problems, there must be some kind of international environmental agreement. One possibility is to have an international environmental agreement focusing directly on emissions in each country. Given such an agreement, an...

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...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

The paper discusses the decisions on the CAP in the context of the Berlin summit. In a rather broad perspective the agricultural sectoral and related objectives are analyzed for their consistency and compatability with higher ranking societal objectives. The policiesÂ’ allocational and...

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...
