US renewable fuels policy strongly encourages biomass crop production, which should lead to expansion of biomass heating scenarios. Chemical composition of grass biomass can be extremely variable, depending on species, soil fertility, and harvest management. Biomass quality concerns have...

Simulation models are effective tools to examine interactions between livestock, cropping systems, households, and natural resources. Our study objective was to use an integrated livestock and crop model to assess the outcomes from selected suites of management decisions observed in smallholder...

Mixed farming systems constitute a large proportion of agricultural production in the tropics, and provide multiple benefits for the world's poor. However, our understanding of the functioning of these systems is limited. Modeling offers the best approach to quantify outcomes from many...
