This paper compares environmental and profitability outcomes for a centralized biorefinery for cellulosic ethanol that does all processing versus a biorefinery linked to a decentralized array of local depots that pretreat biomass into concentrated briquettes. The analysis uses a spatial...

Cowpea (Vigna unguiculata) is an important staple in Burkina Faso as well as many other countries in West Africa. Among the major cowpea pests affecting the crop are the legume pod borer (Maruca vitrata), flower thrips (Megalurothrips sjostedti), bruchids (Callosobruchus maculatus), and...

Biomass is being researched as a possible alternative to fossil sources of energy, in order to avoid externalities from fossil fuel use that affect the environment and the economy. Some biomass-based energy production systems may produce unwanted externalities in their own right, such as...

This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws...

Advanced biofuels such as cellulosic ethanol are of great interest for their potential to supply a significant portion of U.S. fuel needs plus advantages over corn grain-based ethanol. The sustainability of agriculture-based advanced biofuels depends on how farmers would respond in providing...

This paper demonstrates that there is relatively little association between field slope and crop cover in Rwanda, and examines the question of how this could be so in this highland African nation.

Although several studies have been conducted to determine the viability of conservation agriculture in Sub-Saharan Africa, almost all such studies are fragmented – often country specific – and with undue emphasis on output effects. However, assessment of the attractiveness of these...

Previous studies have identified regulatory preemption and differentiation as two main motives for participation in voluntary environmental programs (VEPs). This research examines the motivations of livestock farmers to participate in the Michigan Agricultural Environmental Assurance Program...
