In Mexico, 45 percent of the country suffers from land degradation, 12 percent of which, or some 23 million ha, are degraded due to water erosion. In Michoacán, a state in west-central Mexico, the figure rises to 27 percent. A study of the soil in Michoacán determined that overgrazing was a cause of degradation and a strategy was drawn up to promot...
The main challenges of Tunisian arid areas is better understand desertification and better adapt decisions to uncertainties that arise in complex interactions between the socio-economic and biophysical dynamics at different spatial and temporal scales. This understanding is increasingly necessary to better target actions and improve coping strategi...
Les Tanala, paysans de l'Est de Madagascar, pratiquent une culture temporaire sur défriche-brûlis appelée tavy, souvent perçue comme une cause d'érosion du sol L'accroissement de l'activité cyclonique, facteur d'érosion et d'inondations, appelle alors des stratégies d'adaptation. Supposant que les pratiques de tavy comportaient une stratégie pour f...

A volcanic tuff rock known as cangahua (Ecuador) or tepetate (Mexico) is found throughout the Andes. Problems have arisen as the layers of light but fragile soil that once covered the tuff have been lost for both natural (environmental) reasons and because of over-cultivation. When the soil is gone, the tuff is impermeable and sterile. Now, a proje...
