La précarité de la sécurité et de la souveraineté alimentaire dans les pays en développement
cause la mort de milliers de personnes quotidiennement. Or, la hausse démographique et les
changements climatiques accentueront cette situation déjà alarmante. Une forte croissance
de la production agricole devra être atteinte pour répondre à la hausse de la demande en
n response to global climate change, loss of biodiversity, and the immense human impact on the carrying capacity of the earth systems, attention has been given to sustainable development worldwide. In this paper, we explore the emerging field of sustainability science within the context of the socio‐cultural milieu of Malawi, a sub‐Saharan African country.
Samples of dried shea fruit pulp were collected from tree populations in Mali, Burkina Faso, northern Cameroon, and Uganda. A variety of analytical methods was used to measure total soluble solids (TSS), crude protein, and mineral contents.

The challenge of producing food for a rapidly increasing population in semi-arid agro-ecosystems in Southern Africa is daunting. More food necessarily means more consumptive use of so-called green water flow (vapour flow sustaining crop growth). Every increase in food production upstream in a watershed will impact on water user and using systems downstream.
Sustainable intensification of smallholder farming is a serious option for satisfying 2050 global cereal requirements and alleviating persistent poverty. That option seems far off for Sub-Sahara Africa (SSA) where technology-driven productivity growth has largely failed.
Climate change, population growth, increasing water demand, overexploitation of natural resources and environmental degradation have significantly degraded the world’s freshwater resources. In sub-Saharan Africa (SSA), the number of countries where water demand outstrips available resources is increasing.
Background and context This paper explores the links between farmer organisations, Fairtrade and adaptation to climate change, and the extent to which such institutions and market arrangements can enhance the adaptive capacity of smallholder farmers.
Climate change presents a profound challenge to food security and sustainable development in Africa. Its negative impacts are likely to be greatest in the African region, which is already food insecure. In the face of global climate change and its emerging challenges and unknowns, it is essential that decision makers base policies on the best available knowledge.
