Soil fertility decline is a major constraint to crop productivity on smallholder farms in Africa.
Agriculture is one of the biggest sources of greenhouse gases. Rice production has been identified as one of the major sources of greenhouse gases, especially methane. However, data on the contributions of rice towards greenhouse gas emissions in tropical Africa are limited.
Multipurpose mosaic (“ecoagriculture”) landscapes can serve the purpose of land sharing to combine objectives of agricultural production and biodiversity conservation. Rewarding the people who shape and maintain those landscapes could act as a mechanism to generate added-value representing an indirect payment for ecosystem services.
Adequate operation and maintenance (O&M) of irrigation infrastructure sustains irrigation scheme facilities, reduces repair costs, helps the system last longer, and keeps irrigation efficiency at design levels.
The knowledge of runoff discharged by a catchment at its outlet is important for water accounting and water allocation to competing uses. Runoff generated by a catchment is important in determining the catchment water balance, estimating pollutant loads, and quantifying sediment yield and delivery ratio.
Water has a low profile in Comprehensive Africa Agriculture Development Programme (CAADP) processes in the Southern African Development Community (SADC), presenting an opportunity to develop stronger ties between the agriculture and water sectors in the region.
The report below contains the proceedings of the first workshop of a joint project by Zambia's Ministry of Agriculture and Livestock (MAL), The Food and Agriculture Organization of the United Nations (FAO) and The CGIAR programme on Climate Change, and Agriculture and Food Security (CCAFS) who are collaborating on developing and quantifying participatory scenario analysis under an EC funded pro

Twenty-seven nations are classified as ‘water scarce’, a further 16 as ‘water stressed’. This situation, coupled with the fact that many surface and groundwater systems are shared between two or more states, has led governments to develop sustainable water management strategies.
Ce numéro de Nature & Faune met le focus sur « La place de la jeunesse africaine dans l’agriculture, les ressources naturelles et le développement rural ».
