Desertification in semi-arid northeast of Brazil | Desertificação no nordeste semi-árido do Brasil

Desertification is the process of land degradation in arid, semi-arid and dry sub-humid areas, caused, among other factors, by human activities and climatic variations. It is a global-scale problem because it is present in the dry regions in the world and causes many losses. In Latin America alone,...
