Economic framework for integrating environmental stewardship into food security strategies in low-income countries: case of agroforestry in southern African region

  One of the greatest challenges in many Sub-Saharan Africa countries especially where seasonal food deficits occur frequently, is how best to achieve a balance between the goals of food security and agricultural production on the one hand, and the concerns for the conservation of environmental quality and natural resources capital on the other. A number of agricultural production technologies...

Contributions of agroforestry to ecosystem services in the miombo eco-region of eastern and southern Africa

  The miombo, the most extensive tropical woodland formation of Africa with particular ecological and economic importance, is threatened by deforestation, land degradation and loss of biodiversity. Over the past two decades, agroforestry has been studied as one of the integrated natural resource management interventions for addressing various environmental and social problems. This has helped to establish...

Soil nutrient content, soil moisture and yield of Katumani maize in a semi-arid area of Kenya

  Many farmers in Kenya’s semi arid lands cannot afford to purchase inorganic fertilisers to improve their crop yields. They thus rely on traditional agronomic practices such as addition of crop residues, animal manures or intercrops of cereals and legumes. This study investigated soil parameters and their influence on yield. It was carried out at the University of Nairobi’s...

Assessment of the ClimGen stochastic weather generator at Cameroon sites

  Simulation of agricultural risk assessment and environmental management requires long series of daily weather data for the area being modelled. Acquiring and formatting this data can be very complex and time-consuming. This has led to the development of weather generation procedures and tools. Weather generators can produce time series of synthetic weather data of any length, interpolating observed data to...
