This paper explores the value of mangrove systems as a breeding and nursery habitat for off-shore fisheries, focusing on mangrove-shrimp production linkages in Campeche State, Mexico. We develop an open access fishery model to account explicitly for the effect of mangrove area on carrying...

In this paper, we propose a methodology, based on materials accounting and operational research techniques, to assess different industry configurations according to their life cycle environmental impacts. Rather than evaluating a specific technology, our methodology searches for the feasible...

There is now increasing recognition that the world's marine ecosystems, especially coastal areas and semi-enclosed seas, are suffering from degradation and modification due to human influences. One of the most serious problems is nutrient enrichment, which in the long term harms productivity and...

Policy debates on trade and the environment frequently refer to a need for countries linked by trade to co-ordinate, or even harmonise, their purely domestic environmental policies. Underlying this argument is a concern that national governments will not fully internalise environmental...

This paper concerns optimal emissions of greenhouse gases when catastrophic consequences are possible. A numerical model is presented which takes into account both continuous climate-feedback damages as well as the possibility of a catastrophic outcome. The uncertainty in the model concerns...

The aim of this study is to establish a classification for environmental indicators that can be used to communicate companies' environmental performance in Emas Environmental Statements and to assess their actual use in certified Environmental Statements. Starting from the ISO14031 draft...

This paper considers the relationship between natural resource management and poverty by analysing a specific example: an inland fishery in Bangladesh. The analysis involves substantial extensions to standard models and allows the simulation of market distortions and alternative management...

Although the economic effects of CO2 abatement depend substantially on the degree to which capital and labor can substitute for energy, the issue of energy-capital-labor substitution is surrounded by considerable uncertainty. In this paper we use econometrically estimated, sectorally...

An important evaluation problem in developing countries is assessing the value and optimal use of environmental resources as inputs into production. This is a key methodology required for many general evaluation approaches, e.g. ensuring the most efficient use of a resource requires...

This paper explores the link between poverty and resource allocation, including the management of natural resources, by chronically indebted rural smallholders in developing countries. The paper proposes a formal intertemporal model of a credit constrained farm household that can invest in...
