St. Vincent and the Grenadines is an archipelagic state of the Caribbean that regularly suffers natural disasters; climate change is increasing the frequency of intense hurricanes and storms. The southernmost watersheds of St. Vincent have a rugged topography that favours flash-flooding in rainy events, with great damage because the area concentrates most of the country's population and infrastructure. To deal with this problem the Government has developed studies, engineering works and a watershed management plan. Land use management is an effective way of controlling hydrological impacts; the plan divides the watersheds in three uses, nature conservation (46%), agriculture and agroforestry (24%), and urban (30%), with categories, establishing permitted, prohibited and restricted activities. The area is close to the limit of urban development; if further expansion were essential it should be done by increasing density in lower and flatter areas. Many houses, usually low-income settlements, are in flooding or landslide risk areas, which should be decolonized, changing land use. It is also necessary to avoid hillside arable crops. Adaptation to climate change through land use management is essential, although unfortunately less socially and politically appreciated than engineering works. [ABSTRACT FROM AUTHOR]
