A bioeconomic model is developed to analyze the optimal control management strategies for an introduced herbivore in a two-compartment ecosystem. This paper analyzes cost-effective control strategies that decrease the spillover effects of the herbivore on endangered plant species, thereby...

The 1989 collapse of trade relations with the former socialist bloc plunged Cuba into an economic and food crisis. Cuban farmers, scientists, and planners have responded with alternative agricultural technology to make up for imported food and Green Revolution inputs that are no longer...

Over the past several decades, a group of scholars at the Berkeley campus of the University of California have frequently challenged many of the dominant themes of contemporary agricultural research. In their work, they have organized curricula questioning the assumptions of conventional...

A participatory rural appraisal inthree West African countries examined thepossibility for replacing chemical pesticidesto control locusts and grasshoppers with abiological control method based on anindigenous fungal pathogen. The fungus iscurrently being tested at different sites inthe Sahel...

Biological control of pests is an important ecosystem service in agricultural landscapes as it protects crops and reduces the need for insecticide use. Establishing a sustainable bioenergy industry requires considering the role of biological control in farm decision making. An important question...

The Leafy Spurge Biological Control program was designed to use insects and plant diseases from the plant's original European habitat to control infestations in the United States. The widespread adoption of biological agents to combat leafy spurge and the initial success in reclaiming previously...

The management of non-native invasive species is a complex but crucial task given the potential for economic and environmental damages. For many invasions the development of socially optimal control strategies requires more than is offered by the single-species, single-control models that have...

Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al....

The probability of alienspecies invasion is reasonably characterized by a weakest link technology. A tradeableriskpermit system for shippers has been proposed as a means of efficiently reducing this invasion probability. Economic jointness arising from statistical independence among private...
