This study investigates the household-level impacts of market-oriented dairy technologies (crossbred cows and complementary feed and management technologies) on in-comes, food and non-food expenditures, nutrient intakes, and health of pre-school children. A recursive econometric model was employe...

Livestock are an important component of farming systems in sub-Saharan Africa. They are raised mainly for meat, milk and skin and provide a flexible financial reserve in years of crop failure. They also play a critical role in the agricultural intensification process by providing draft power and ...

Using a household bioeconomic modelling approach, this paper analyses the impact of advancing in-kind credit in the form of fertilizer and seed on smallholder farmers with different levels of wealth in the Ethiopian highlands. Cropland allocation and household consumption patterns are examined in...
