Scientific information on the spatial variability and distribution of soil properties is critical for understanding ecosystem processes and designing sustainable soil–crop and environmental management decisions. However, little is known on spatial distribution and variability of soil properties a...

Though soil quality (SQ) degradation is a serious challenge to national food security, little information is available that evaluate farmer SQ knowledge vis-à-vis scientific knowledge at catchment scale in Ethiopia. Scientific soil analysis is not an effective approach for SQ assessment in develo...

Due to increased population pressure and limited availability of fertile land, farmers on desert fringes increasingly rely on marginal land for agricultural production, which they have learned to rehabilitate with different technologies for soils and water conservation. One such method is the ind...

The Volta Basin covers 400 000 km of the West-African Savanna. Agriculture is the dominant ecnomic activity. Given the extremely unreliable rainfall, irrigation development is seen as an obvious strategy to increase agricultural production. Irrigation development is mainly linked to the construct...

Land and water degradation due to on-site soil/nutrient loss and off-site pollution/sedimentation are serious environmental problems. Landscape planning and management tools are essential to implement best management practices targeted at locations where they are needed most. Although many soil/w...

There is a significant gap between the rhetoric of claims about adoption of farm-level natural resource management practices and the reality. New empirical evidence of low adoption from several developing countries suggests that on-farm natural resource management practices face significant const...

A study was carried out in the Sudan savanna zone in the Upper East Region of Ghana to assess the rate of sediment-bound nutrient export (NE) into five small reservoirs (Dua, Doba, Zebilla, Kumpalgogo and Bugri) and to analyse the implications of this export. The catchment soils and reservoir sed...
