Ecosystem service-support tools are commonly used to guide natural resource management. Often, empirically based models are preferred due to low data requirements, simplicity and clarity. Yet, uncertainty produced by local context or parameter estimation remains poorly quantified and documented. ...

Reviews the appropriateness of three major assumptions underlying pastoral development in East Africa, viz, economic irrationality of pastoralists, the unchanged nature of pastoral production systems, and the applicability of western models to pastoral development.

Estimates moisture availability in Ethiopia since 1953, using a model developed by the FAO; correlates results of the analysis using existing meteorological data with the recorded incidence of drought and famine.

Evaluates alley farming models with small ruminants based on field and experimental data from southwest Nigeria, and compares them to basic alley cropping and to fallow systems. Describes the basic fallow model, the basic alley cropping model without animals, the alley farming model with goats, a...

The knowledge about high temperature effect on plant crop is important for adaptation strategies to Climate Change. For this reason the aim of the paper was to analyze its abiotic effect on common bean cultivation in a Red Ferralitic soil. A sowing of twelve varieties was performed in non-optimum...
