Ethiopia has the largest livestock population in Africa but the contribution of this resource to the economy is limited and yet the country is in poverty. Dairy development has a big role for the contribution of income generation and employment. Demand for dairy products seems to exceed supply in the country in general and the study area in particular. Hence, the situation of dairy production a...

A representative sample of 49 state and collective farms in Ukraine provides data in physical units on livestock and crop production and input use for 1989-92. The changes in production efficiency for beef, pork, dairy, winter wheat, grain, and potato production, investigated using stochastic frontier methods, show declining technical efficiency in livestock production and especially low margin...

Abstract Small family farms account for 72% of the in world. Most these farms, developing countries, face labor productivity gaps. One strategies to increase agricultural focuses on implementing technical assistance programs. Using agriculture microdata, we estimate marginal treatment effect receiving services. We find that generates heterogeneous effects. On average, units increased their prod...

Natural ecosystems benefit human communities by providing ecosystem services such as water purification and crop pollination. Mapping ecosystem service values has become popular, but most are static snapshots of average value. Estimating instead the economic impacts of specific ecosystem changes can better inform typical resource decisions. Here we develop an approach to mapping marginal values...

The Mediterranean Basin is a climate and biodiversity hot spot, and climate change threatens agro-ecosystems such as olive, an ancient drought-tolerant crop of considerable ecological and socioeconomic importance. Climate change will impact the interactions of olive and the obligate olive fruit fly (Bactrocera oleae), and alter the economics of olive culture across the Basin. We estimate the ef...

One of the most evident elements of the agricultural crisis is farm abandonment in many marginal rural areas, such as mountains. Some traits of mountain agriculture such as remoteness, low productivity, extreme weather and small farm size, can limit the adaptation and the competitiveness of this branch. The analysis aims to assess the consumers’ Willingness to Pay (WTP) for permanence of the up...

Forage is included in beef cattle growing or finishing diets for several reasons. Nutritionally, forage provides protein, vitamins and minerals. When included as a minor component of high grain finishing diets, forage may increase feed intake and reduce nutritional disorders due to increased salivation, rumination and passage rate. Manipulating dietary moisture content through inclusion of dry ...

We develop a dynamic groundwater model that incorporates both groundwater pumping and investment in deeper wells and apply the model to the arid, alluvial aquifer region of Northern India that is experiencing rapid depletion. We compute the potential benefits of regulating groundwater use by comparing the net benefits of groundwater under optimal management to the net benefits under a common po...
