This chapter uses one particular bio-economic model, first, to explore some questions and hence generate information pertaining to the complex interactions existing in an integrated crop-livestock farming system in Ethiopia. Secondly, it examines various ways in which such a model may be used to ...

GIS-derived measures of location and space have increasingly been used in models of land use and ecology. However, they have made few inroads into the literature on technology adoption in developing countries, which continues to rely mainly on survey-derived information. Location, with all its di...

Representation of land-use and hydrologic interactions in respective models has traditionally been problematic. The use of static land-use in most hydrologic models or that of the use of simple hydrologic proxies in land-use change models call for more integrated approaches. The objective of this...

Climate change science has been discussed and synthesized by the world's best minds at unprecedented scales. Now that the Kyoto Protocol may become a reality, it is time to be realistic about the likelihood of success of mitigation activities. Pastoral lands in the tropics hold tremendous sequest...

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...
The cycling of biomass through livestock into manure and urine that fertilise the soil is important linkage between livestock and soil productivity in semi-arid West Africa. This study was conducted to determine the effects of different forage leaves on the amounts and forms of nutrients excreted...

Presents results of economic analysis carried out in southwestern Nigeria to determine the profitability of alternative land use systems, taking into account the short and long-run impact of soil erosion on agricultural productivity. The fallow systems include 1. two continuous cultivation alley ...
