Vandeplas, IVanlauwe, BernardDriessens, LMerckx, R.Deckers, J.[Reducing labour and input costs in soybean production by smallholder farmers in south-western Kenya]Reducing labour and input costs in soybean production by smallholder farmers in south-western Kenya

Transhumance, the seasonal movement of herds occurring between two points and following precise routes repeated each year, is practiced on a broad scale in the open field areas of Tigray (North Ethiopia). This article presents a characterization of the practice, factors that explain its magnitude...


Nyssen, JanDescheemaeker, KatrienZenebe, A.Poesen, J.Deckers, J.Haile, M.[Transhumance in the Tigray highlands (Ethiopia)]Transhumance in the Tigray highlands (Ethiopia)

The establishment of exclosures (i.e. areas closed for grazing and agriculture) is a common practice to reverse land degradation through vegetation regeneration in the semiarid highland areas of northern Ethiopia. In order to assess the effect of exclosures on water flows, the water balance compo...


Descheemaeker, KatrienRaes, DirkNyssen, JanPoesen, J.Haile, M.Deckers, J.[Changes in water flows and water productivity upon vegetation regeneration on degraded hillslopes in northern Ethiopia: a water balance modelling exercise]Changes in water flows and water productivity upon vegetation regeneration on degraded hillslopes in northern Ethiopia: a water balance modelling exercise

Studies on the impacts of environmental rehabilitation in semi-arid areas are often conducted over limited space and time scales, and do typically not include detailed biophysical components. This study makes a multi-scale assessment over a time span of 30 years of environmental rehabilitation in...


Nyssen, JanPoesen, J.Descheemaeker, KatrienHaregeweyn, N.Haile, M.Moeyersons, J.Frankl, AmauryGovers, G.Munro, N.Deckers, J.[Effects of region-wide soil and water conservation in semi-arid areas: the case of northern Ethiopia]Effects of region-wide soil and water conservation in semi-arid areas: the case of northern Ethiopia

Nutrient depletion is a major constraint to crop production for moist savanna soils, and inputs of nutrients are required to overcome this constraint. The impact of sole and combined applications of organic inputs (OIs) [fresh tree prunings, Pueraria phaseoloides (Roxb.) Benth. residues, and manu...


Vanlauwe, BernardAihou, K.Aman, SIwuafor, E.N.O.Tossah, B.K.Diels, J.Sanginga, NteranyaLyasse, O.Merckx, R.Deckers, J.[Maize yield as affected by organic inputs and urea in the West African moist savanna]Maize yield as affected by organic inputs and urea in the West African moist savanna

In the context of major global environmental challenges such as food security, climate change, fresh water scarcity and biodiversity loss, the protection and the sustainable management of soil resources in Africa are of paramount importance. To raise the awareness of the general public, stakehold...


Dewitte, O.Jones, A.Spaargaren OBreuning-Madsen HBrossard MDampha, A.Deckers, J.Gallali THallett SJones, R.Kilasara MLe Roux PMichéli EMontanarella LThiombiano, L.Ranst, E, vanYemefack MZougmoré, Robert B.[Harmonisation of the soil map of Africa at the continental scale]Harmonisation of the soil map of Africa at the continental scale

Although the fertility status of soils in the West African moist savanna is generally believed to be low, crop yields on farmers' fields vary widely from virtually nil to values near the potential production. The soil fertility status was evaluated for a number of farmers' fields selected at rand...


Vanlauwe, BernardDiels, J.Lyasse, O.Aihou, K.Iwuafor, E.Sanginga, N.Merckx, R.Deckers, J.[Fertility status of soils of the derived savanna and northern guinea savanna benchmarks and response to major plant nutrients, as influenced by soil type and land use management]Fertility status of soils of the derived savanna and northern guinea savanna benchmarks and response to major plant nutrients, as influenced by soil type and land use management

Impact studies of catchment management in the developing world rarely include detailed hydrological components. Here, changes in the hydrological response of a 200-ha catchment in north Ethiopia are investigated. The management included various soil and water conservation measures such as the con...
