Estimation of the mineral resources potential is an important issue for most of developing countries. The spatial distribution of bauxites and lateritic land surfaces on the Bamiléké plateau (West Cameroon) has been investigated with a Boolean modeling process into a GIS environment on the basis ...
When urban areas expand without concomitant increases in wastewater treatment capacity, vast quantities of wastewater are released to surface waters with little or no treatment. Downstream of many urban areas are large areas of irrigated croplands reliant on these same surface water sources. Case...
Strict hydrologic definitions of basins coupled with technological advances including the use of remote sensing and geographic information systems have given us more accurate and detailed knowledge than ever before about the scale and extent of transboundary waters. This information has had both ...
Historical and recent aerial photograph and satellite images were analysed to study the change of land use/land cover and soil degradation in different agroecological zones of Nigeria and Benin. The sites were characterized by an expansion of farmland at the expense of forest and shrub, fallow an...
Insect pests often develop resistance to insecticides, and such resistance represents a serious management problem. Devising methods that concurrently delay resistance and minimize injury by insects to field crops and stored grain has long been a goal of Integrated Pest Management (IPM). A center...
Pests and diseases of bananas (Musa spp.) threaten the livelihoods of over 20million people in the Great Lakes region. Geographic information systems (GIS)provide valuable tools in monitoring, predicting, managing and fighting the spreadof pests and diseases. The tools offer opportunities for cos...
