Anwar, Arif A.Aynalem, D.W.Tilahun, Seifu A.Mekuria, Wolde M.Azeze, M.Steenhuis, Tammo S.[Effectiveness of land and water management interventions in reducing runoff and soil erosion in the northwestern highlands of Ethiopian [Abstract only]]Effectiveness of land and water management interventions in reducing runoff and soil erosion in the northwestern highlands of Ethiopian [Abstract only]

Sustainability of their agricultural systems is essential for many tropical countries where the majority of the people depend upon agriculture for their livelihoods. In the short term economic sustainability is the main factor influencing viability of an agricultural system and of the farms which...


Utiger, C.Romney, D.L.Njoroge, L.Staal, Steven J.Lukuyu, Ben A.Chege, L.[Nutrient flows and balances in intensive crop-dairy production systems in the Kenya highlands]Nutrient flows and balances in intensive crop-dairy production systems in the Kenya highlands
Autor: Dijkman, J.

Rapid increases in population densities and the associated environmental changes have meant increased problems for farmers in planning effective resource management strategies. In response to these driving forces and to improve the efficiency of the use of the available nutrient resources many tr...

In semi-arid sub-Saharan Africa as in many dryland areas, livestock are an integral part of the farming systems. Livestock offer opportunities for risk coping, farm diversification and intensification and provide significant livelihood benefits to the poor. The ability of livestock systems to con...

Result of long time alley cropping trials show that the inclusion of N2- fixing hedgerow species maintain higher levels of soil fertility than control treatment (no hedgerow) on high base status soils in the humid zone. Hedgerows contribute to nutrient cycling and higher faunal activity. With goo...

The integration of crops and livestock has often been cited as a model for agricultural development in semi-arid West Africa. Recent formulations treat the adoption of more intensive forms of manuring as a critical step in agricultural development. These analyses have been criticised for ignoring...


Turner, M.[The sustainability of rangeland to cropland nutrient transfer in semi-arid West Africa: ecological and social dimensions neglected in the debate]The sustainability of rangeland to cropland nutrient transfer in semi-arid West Africa: ecological and social dimensions neglected in the debate

Mixed farming systems in semi-arid West Africa rely on recycling organically bound nutrients to maintain soil productivity. The passage of plant biomass through ruminant livestock plays a major role in the nutrient cycles of this region. The feeding value of crop residues and browses and their im...

To assess the current situation of municipal solid waste (MSW) composting opportunities and potential acceptance of nutrient enriched pelletized compost in Sri Lanka,two field surveys were conductednationwide and in Kurunegala (Northwestern) area, respectively. Due to the low nutrient content of ...
