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...

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...

Increasing climate variability and challenge in access to water pose major impediments to rainfed agricultural productivity. Extensive flooding of agricultural lands during the rainy season and lack of water during the 8-month long dry season affect the livelihood of the people in the northern Gh...

Remote sensing and GIS tools have broadly helped hydrogeologists to delineate the groundwater prospective zones for watershed development and management. The origin, movement and existence of groundwater depends on several factors such as slope, drainage density, land use, geology, lineament dens...

Deficit irrigation could be considered as one potential option to improve water productivity and obtain some level of assured income under water scarcity and drought conditions in Central Asia. This article investigates water productivity and economic returns to two varieties of potato crop under...
