The Burkina Faso authorities have sounded the alarm over the increased rate of degradation of forests in this Sahelian country. According to a study by the Ministry for the Environment and Sustainable Development, some 110,550 hectares of forest are destroyed each year, just over four per cent of the country's total wooded area – around three-quarters of this annual loss linked to farming. The data covers forest loss between 1992 and 2002, but the trend continues, according the ministry.
