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...

An empirical investigation is undertaken into the impact of the Structural Adjustment Programme (SAP) on Forest and biodiversity loss in Ghana between the period 1965-1995. In the first part of the analysis, a four-equation recursive model, consisting of forest loss, cocoa land, maize land and...

We provide an overview and introduction to the emerging field of trade and renewable resources, and discuss the potential impact of trade liberalization on welfare and resource conservation. A key factor determining the effect of trade reform is the institutional context or property right...

Remittances to developing countries exceed $550 billion annually. Although many poor rural households that depend on these remittances also harvest local common-pool resources, few studies explore this relationship. We develop a dynamic model of a coastal fishing household with remittance...

We model biological invasions as an unintended by-product of capital accumulation. We distinguish three spillover effects: (1) a negative production externality, (2) a negative or positive consumption externality and (3) an increase in the risk of future welfare loss. We also consider the...

Populations in developing countries that are located in less-favored agricultural areas (LFAA) – i.e., agricultural lands constrained by difficult terrain, poor soil quality, limited rainfall, etc. or with limited access to markets – and rural low-elevation coastal zones (LECZ) – i.e.,...

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...

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...
