The economic and environmental benefits of gum arabic production in the Sudano-Sahelian zone appear attractive. However, the farm-level economics of gum arabic production is complex, and much more needs to be understood about the economic-environmental interactions determining farmers' gum...

In response to the world economic crisis, the international community should promote a mix of policies to sustain global recovery and create jobs through reducing carbon dependency, ecological degradation and poverty. Such a Global Green New Deal (GGND) requires implementation and coordination...

As the world recovers from the worst economic crisis since the Great Depression, the international community should promote a mix of policies to sustain this global recovery and create jobs through reducing carbon dependency, ecological degradation and poverty. Such a Global Green New Deal...

Nutrient enrichment of marine ecosystems is regarded as a pressing global environmental problem. For certain marine species it may be a mixed blessing, resulting in damaging ecosystem events, but contributing to primary productivity. Consequently, the impact of enrichment on fishery profits may...

Bilateral trade and capital flows have increased substantially between the United States and China yielding economic gains to both countries. However, these beneficial bilateral relations also bring about global environmental consequences including greenhouse gas emissions. We develop a...

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...

Optimal management of biodiversity at the national level, even if achievable, is not necessarily consistent with a global optimum. While the existence of trading relationships allows for the possibility of the use of trade interventions as a means of imposing unilateral solutions, the presence...

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...

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...
