Measuring ammonia (NH3) volatilization from urea-fertilized soils is crucial for evaluation of practices that reduce gaseous nitrogen (N) losses in agriculture. The small area of chambers used for NH3 volatilization measurements compared with the size of field plots may cause significant errors if inadequate sampling strategies are adopted. Our aim...

Field studies on soil ammonia (NH3) volatilization are restricted in many countries owing to the high costs commonly demanded for accurate quantification. We assessed the accuracy of a simple, open chamber design to capture NH3 under field conditions, as affected by different chamber placement schemes. Urea-15N was surface applied to lysimeters ins...

Technology adoption has been proven to be an efficient way to improve agricultural productivity as well as farmers’ income across the semi-arid regions of the globe. However, an upcoming method to improve food and livelihood security is through sustainable technology intensification. The study tries to assess the impact of climate-smart agriculture...

This working paper explores a generic method that can be used to benchmark nitrogen (N) input requirements for crop production and the efficiency by which inputs are used. Two types of N benchmarks are introduced: one for short-term and another for long-term assessments. We explain the underlying assumptions, data requirements and types of applicat...

This working paper presents results of an impact assessment of management innovations that were introduced in agricultural carbon projects in East Africa. We evaluated the effect of project design, management, and monitoring transfer of responsibilities to local communities on the performance of agricultural carbon projects. The assessment included...

Livestock production is an important source of incomes and livelihoods for the rural population in Ethiopia, and is also an important contributor to greenhouse gas (GHG) emissions. Ethiopia’s GHG profile is dominated by emissions from the agriculture sector, representing 79% of total national emissions. Of these emissions, livestock accounts for th...
