System Dynamics Modelling Approach to Determine Sustainable Stocking Rate for a Sheep Population in the Ethiopian Highlands
A system dynamics approach was used to determine the sustainable stocking rate of the Menz sheep population in the Ethiopian highland. A model was developed to simulate stocking rate based on communal grazing land. The ...
Reflection on innovation processes in a smallholder goat development project in Mozambique
There is an increasing interest among researchers, practitioners and donors in using agricultural innovation systems approaches to reach development outcomes. Limited practical experiences have been shared on the dynamics ...
A methodological approach to model the grass-tree relationship in Quercus suber Mediterranean forest ecosystems
Livestock is socially and economically an important component for the livelihood of resource poor
farmers in North Africa. A portion of livestock feed resources is forest rangeland. Unfortunately, the
sustainability of ...
Closing the Feed Gap in Drylands for Enhanced Livestock Productivity and Efficient Resource Use
Livestock is the world’s fastest-growing highest-value agricultural sub-sector already accounting for about 40 % of agricultural GDP globally. By 2050 massive increases over 2005/7 amounts of cereals, dairy and meat will ...
The Subjective Well-being Effects of Imperfect Insurance that Doesn’t Pay Out
In this paper we estimate the effects of an imperfect insurance coverage on subjective well-being of a poor, rural population, by exploring whether insurance in force improves subjective well-being and whether insurance ...
Expanding Chickpea in non-traditional Lowlands of Ethiopia
Frequent drought is affecting the mixed farming and agro-pastoral communities in Ethiopia. In
the Agro-pastoral lowlands, maize, sorghum and common bean are the key crops produced by
famers when rainfall is favorable. ...
The effect of grazing exclusion on vegetation characteristics and plant community structure in arid lowland pastures
Rangelands are the mainstay of pastoral livelihoods worldwide. Within rangelands, there are landscape depressions or lowlands characterized by high production potentials with their unique edaphic and hydrologic properties. ...
Opportunities and limitations of multidimensional crop improvement in grain legumes to support increased productivity in mixed crop livestock systems
While rising demand for animal sourced food (ASF) in emerging and developing countries increases feed demand, shrinking natural resource base particularly arable land and water limit feed production. Consequently crop ...
Grassland/rangelands based livestock production systems: Options and trade-offs between productivity and GHG emissions reductions
Conference paper on "Grassland/rangelands based livestock production systems: Options and trade-offs between productivity and GHG emissions reductions."
Productive Spillovers of the Take-up of Index-Based Livestock Insurance¥
Does the provision of livestock insurance raise the unintended consequence of stimulating excessive herd accumulation and less environmentally-sustainable herd movement patterns? The impact of insurance is theoretically ...
