Inefficient management and use of water is unanimously the most single constraint of agricultural production of Ethiopia. The study was conducted to assess the effect of livestock feed sourcing and feeding strategies on livestock water productivity (LWP) in mixed crop–livestock production systems of the Blue Nile Basin in Ethiopian Highlands. Three districts representing diverse agricultural farming systems were considered. Each district further stratified to different farming systems. Multi-stage stratified random sampling technique was employed to select farm households.

Effect of current livestock feed sourcing and feeding strategies on livestock water productivity in mixed crop-livestock systems of the Blue Nile Basin highlands of Ethiopia

The study pertains to livestock management practices & their implications on Livestock Water Productivity (LWP) in the rain-fed crop-livestock systems in the Blue Nile Basin (BNB). Seven farming systems (Rice- Pulse & Teff-Millet from Fogera), (Barley-Potato, Teff-Wheat & Sorghum farming systems from Jeldu) & (Teff-Millet & Sorghum farming systems from Diga districts) were selected & a total of 220 sample Household (HH) heads were involved. Cattle were the major livestock species accounting for 83% of the total Tropical Livestock Unit.

Despite their recognized agricultural sustainability benefits, mixed crop-livestock farms have declined in the Northern hemisphere. As such, crop-livestock integration beyond the farm level is a promising alternative to this trend, but the knowledge of critical factors and strategies towards its successful implementation is still lacking. We developed an analytical framework to assess the critical determinants of the emergence and outcomes of integration, which helped us understand farmers’ collective strategies for reducing integration transaction costs.

Recent forecasts show a need to increase agricultural production globally by 60% from 2005 to 2050, in order to meet a rising demand from a growing population. This poses challenges for scientists and policy makers to formulate solutions on how to increase food production and simultaneously meet environmental targets such as the conservation and protection of water, the conservation of biodiversity, and the mitigation of greenhouse gas emissions.

Discussions about climate change have repeatedly regarded livestock as responsible for a significant contribution of greenhouse gas emissions. However, proper management schemes for livestock production may contribute to a reduction in emissions and, at the same time, induce optimization of production systems and intensification of food production.
