En zones de savanes cotonnières d'Afrique centrale, les densités de populations sont variables et en augmentation. Les modes d'exploitation agricole varient de l'agriculture itinérante répandue en Centrafrique à l'agriculture continue dominante au Cameroun et au Tchad. L'exploitation agricole familiale est une unité familiale de production, de consommation, d'accumulation et de résidence.

This study examines the effect of land rights on agricultural outcomes in Rwanda. We characterize the effects of land rights from two perspectives. The first one is land rights indicated by the right to sell and guarantee land and the second one is land titling. The agricultural outcomes include agricultural productivity, food security and nutritional diversity. From the results, land rights are found to have a positive relationship with all the outcome variables. The effect of land rights on agricultural productivity is larger if the household head is male.

Maize is a critical staple cereal across Sub-Saharan Africa but attempts to improve its productivity in small-scale farming systems often prove disappointing. The 12 key technologies required to overcome poor yields are mostly known, but the manner that they are mobilized, packaged, and delivered requires re-evaluation. Combinations of better varieties and their necessary accompanying inputs must become more available and affordable for an African maize revolution to succeed, and land must be managed in ways that enhance, rather than diminish, land quality over time.

While climate services for small-scale farmers are gaining recognition for contributing to adaptation and resilience to climate variability and change, their provision in developing countries remains a critical challenge. Effective climate services consider why and how farmers of varied socioeconomic background make relevant decisions avoiding the traditional prescriptive forms of transfer that merely focus on delivering climate information.

Ethiopia's highland mixed crop-livestock farming system is one of the country's primary agricultural systems, where crop and livestock production is integrated. However, Ethiopia's mixed farming system, which is dominated by resource-poor smallholder farmers, is frequently confronted with feed shortages and land degradation in the form of soil erosion and nutrient depletion, resulting in low agricultural production. Assuring sustainable agricultural output (both from crop and livestock sub-sector) in the mixed crop-livestock system is becoming a key challenge.

Sustainable intensification practices suitable for smallholders in southern Africa will be needed to counteract the impact of future climate change and soil fertility decline in the region. Diversification of maize-based farming systems with grain legumes could play a key role. Here, we compared the performance of different maize-legume diversification strategies (single-row intercropping, strip cropping, and crop rotation) with sole cropped maize under conventional ploughing and Conservation Agriculture in four Zambian districts in the Eastern and Southern Provinces.

Key messages
• Population growth, changing diets, and a rapidly growing feed sector are contributing to a sharp increase in global maize demand which is expected to double by 2050 relative to 2010.
• Average global maize yield is projected to decrease by 11% under a global warming scenario of 2.0 °C (2060-2084) relative to the 1986–2005 period (in the absence of technological change, adaptation, or market adjustments).

The brief talks about the emerging insights from a Climate-Smart Village in Southern Shan State, Myanmar. It documents a range of coping strategies that help farmers deal with impacts of climate change.

Dairy development provides substantial potential economic opportunities for smallholder farmers in East Africa, but productivity is constrained by the scarcity of quantity and quality feed. Ruminant livestock production is also associated with negative environmental impacts, including greenhouse gas (GHG) emissions, air pollution, high water consumption, land-use change, and loss of biodiversity.
