South Africa in general has been approximately 2% hotter and at least 6% drier over the ten years between 1997 and 2006 compared to the 1970s. The use of water has also increased greatly over this same period. By 2000, 98.6% of that year's surface water yield and 41% of the annual utilisable potential of groundwater was allocated to use.
This study examined farmers’ adaptive measures to climate change induced natural shocks through past climate experiences in the Mekong River Delta (Vietnam) from a data set of 330 farmers. Seemingly unrelated regression model was used to identify the determinants of farmers’ adaptive measures.
Forests are vulnerable to climate change and are also major sources of livelihood for many
rural households in Africa. This study examines rural people’s perceptions of climate change
impacts on forest-based livelihoods using rural communities of Vhembe District in South
Africa as a case study. The study was based on the principles of perceived impact-based
Climate change threatens the livelihood of rural communities that depend on natural resources for food. Many people in developing countries living in the rural areas depend on indigenous food resources which in years are scarce and in poor supply as a result of marginal and erratic rainfall, low soil and ambient temperatures below the minimum temperature.
Climate change is expected to have serious environmental, economic, and social impacts on South Africa. In particular, rural farmers, whose livelihoods depend on the use of natural resources, are likely to bear the brunt of adverse impacts. The extent to which these impacts are felt depends in large part on the extent of adaptation in response to climate change.
Adaptation to climate change involves changes in agricultural management practices in response to changes in climate conditions. It often involves a combination of various individual responses at the farm-level and assumes that farmers have access to alternative practices and technologies available in the region.
We describe the nature of recent (50 year) rainfall variability in the summer rainfall zone, South Africa, and how variability is recognised and responded to on the ground by farmers. Using daily rainfall data and self-organising mapping (SOM) we identify 12 internally homogeneous rainfall regions displaying differing parameters of precipitation change.
Les oasis marocaines constituent un rempart écologique contre l’avancée de la désertification et une source de revenus pour les populations établies dans ces espaces. Elles recèlent une variété de ressources végétales et animales dans un environnement marqué par de faibles précipitations annuelles.
Décrypter la climatologie d’un espace géographique consiste habituellement en l’interprétation de recherches à partir de corpus de statistiques et d’observations instrumentales. Mais une autre source de connaissances est celle des savoirs des populations locales. Cette posture est appliquée à la région de l’Imerina, sur les Hautes Terres de Madagascar.
