Many types of analysis require rainfall data, which must often be generated to overcome limitations in the historical record. The ability to model outlying rainfall years satisfactorily is particularly important in risk studies. We describe a rainfall generator with this ability, based on a third...

The contemporary concern about anthropogenic release of greenhouse gas (GHG) into the
environment and the contribution of livestock to this phenomenon have sparked animal
scientists’ interest in predicting methane (CH4) emissions by ruminants. Focusing on milk
production, we address six basic nut...

Global climate models (GCMs) have become increasingly important for climate change
science and provide the basis for most impact studies. Since impact models are highly
sensitive to input climate data, GCM skill is crucial for getting better short-, medium- and
long-term outlooks for agricultural...

To effectively adapt to climate change, farmers, governments, and other stakeholders must understand the potential effects on crop and livestock production.
A major challenge for contemporary conservation policies and practices is formulating workable compromises between wildlife conservation and the people who live with wildlife. We strongly support the view that anthropology has a critical role to play in contributing to our understanding of human-...

Pastoral communities in East Africa are facing considerable challenges arising from shifts in land tenure policy from communal to individual landholdings and high human population growth rates. Over the last 30 years, livestock-to-human ratios have generally declined to levels that will no longer...

A dynamic agriucltural land-use model based on a Markov process and governed by a few simple decision rules is described. Currently, the model is purely conceptual, and was designed with one objective: to investigate the possibility of constructing top-down land-use models based on as few process...
Well-tested computer simulation models of the growth, development, and yield of annual crops are being used for a wide range of purposes, including the prediction of impacts of different management practices and land use systems on food production, farmers' profitability, and the environment. Pr...
