Presents ILCA's research study in the subhumid zone of west Africa regarding the Fulani of Abet. Includes settlement and land use, farmer-interactions, cropping, fallow & crop residue grazing, hired labour, herd management, herd productivity, inovation design & testing, supplementary feeding, leg...

Successful control of tsetse (Glossina spp.)-transmitted trypanosomiasis in the Ghibe Valley, Ethiopia, appears to have accelerated conversion of wooded grassland into cropland. Land conversion, in turn, may have fragmented wildlife habitat. The objective of this paper was to assess the influence...

The moist savannah zone in sub-Saharan Africa is regarded as a high potential area for crop and livestock production. Currently, human labour is the principal source of power for crop production and the level of commercial energy use is very low. Agropastoralism and pastoralism are the principal ...

Men and women interact with water resources and landscapes in different ways, and there are frequent criticisms that little research is undertaken across disciplines to address this issue. Biophysical scientists in particular struggle with how to integrate “gendered” water uses into models that a...

Sustainable land use in periodically dry Brazilian savannas requires a water-saving management. We hypothesized that the annual course of matric potentials (?M) in very-fine, isohyperthermic Anionic Acrustoxes of Pinus plantations (PI), degraded (DP) and productive pastures (PP), no-till (NT) and...

Vulnerability of forest ecosystems in West Africa is likely to be aggravated with current and projected climate and human stresses with implications for adaptation and REDD regimes. This is because vulnerability of the forest ecosystems affects economic sectors and millions of people that depend ...


Idinoba, M.Nkem, J.Kalame, F.B.Tachie-Obeng, E.Gyampoh, B.A.[Dealing with reducing trends in forest ecosystem services through a vulnerability assessment and planned adaptation actions]Dealing with reducing trends in forest ecosystem services through a vulnerability assessment and planned adaptation actions

Many of the services supplied by nature are externalities. Economic theory suggests that some form of subsidy or contracting between the beneficiaries and the providers could result in an optimal supply of environmental services. Moreover, if the poor own resources that give them a comparative ad...

Fire in the forested tropics has profound environmental, economic, and social impacts at multiple geographical scales. Causes of tropical fires are widely documented, although research contributions are from many disciplines, and each tends to focus on specific facets of a research problem, which...
