L’adaptation aux aléas et la gestion du risque sont partout pris en compte dans les systèmes
agraires traditionnels. En effet, le changement climatique global se traduit localement par
plusieurs évolutions qui modifient les conditions de production. La présente étude s’intéresse à la
compréhension des stratégies développées par les producteurs en situation de changements
La dépendance agriculture/pluie soumet la productivité agricole aux contraintes climatiques à Man et à Korhogo et limite fortement la recherche de la sécurité alimentaire. Les producteurs adoptent des techniques traditionnelles de minimisation des risques capitales pour l’amélioration de la productivité des sols et des cultures.
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
In Malawi, production from subsistence rain fed agriculture is highly vulnerable to climate change and variability. In response to the adverse effects of climate change and variability, a National Adaptation Programme of Action is used as framework for implementing adaptation programmes. However, this framework puts limited significance on indigenous knowledge systems (IKS).
The agro-ecological knowledge held by Ovambo farmers in North Central Namibia has, for centuries, given them resilience to high levels of climate variability and associated impacts. New research, conducted in North Central Namibia, suggests that knowledge co-production between farmers and agricultural extension workers may, in addition, strengthen adaptive capacity to future climate change.
The focus of the great majority of climate change impact studies is on changes in mean climate. In terms of climate model output, these changes are more robust than changes in climate variability. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated.
Climate change is now unequivocal, particularly in terms of increasing temperature, increasing CO2 concentration, widespread melting of snow and ice and rising global average sea level, while the increase in the frequency of drought is very probable but not as certain.
Scientific knowledge systems have received increasing criticism within the social science literature while indigenous knowledge systems are often over-optimistically presented as viable alternative ways of knowing. This paper argues that we need to search for more effective and creative interactions between indigenous knowledge and scientific knowledge systems.
Trees inside and outside forests contribute to food security in Africa in the face of climate variability and change. They also provide environmental and social benefits as part of farming livelihoods. Varied ecological and socio-economic conditions have given rise to specific forms of agroforestry in different parts of Africa.
