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...
This document summarizes the findings of participatory organic peanut experiment with three households in My Loi Climate-Smart Village in 2019, funded by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS).
Food system innovations will be instrumental to achieving multiple Sustainable Development Goals (SDGs). However, major innovation breakthroughs can trigger profound and disruptive changes, leading to simultaneous and interlinked reconfigurations of multiple parts of the global food system. The emergence of new technologies or social solutions, the...
More and more cities develop urban food strategies (UFSs) to guide their efforts and practices towards more sustainable food systems. An emerging theme shaping these food policy endeavours, especially prominent in North and South America, concerns the enhancement of social justice within food systems. To operationalise this theme in a European urba...
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 paper reviews the current state of policies and frameworks on climate change, agriculture, food, and nutrition security in Kenya. Integrating climate change in policies and frameworks on agriculture, food and nutrition security is important for providing and strengthening the enabling environment for building farmers resilience and adaptive ca...
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...
In 2020, an experiment was run for the third consecutive season at the Farm for the Future Tanzania Ltd. (FFF), which is part of Ilula Orphan Program’s (IOP) Farm, Ilula, Iringa Region, in Tanzania. The FFF farm is training farmers in 16 villages with a focus on dissemination activities at regional and national levels. The purpose of the experiment...
