AGRICOLTURA

The Food and Agriculture Organisation (FAO) has disclosed that up to 60 per cent of all the land in the world may soon become degraded unless urgent steps are taken to ensure sustainable management of land across the world.

The United Nations (UN) agency stressed that land users around the world must understand that this resource is vital for the continued support of flora, fauna and human life and as such must treat it as a finite material.
“More than 20 per cent of all cultivated land, 30 per cent of forests and 10 per cent of grasslands are under degradation,” FAO, headed by the Director-General, Jose Graziano da Silva, stated.
Stressing that the global food system has profound implications for the environment, and producing more food than is consumed only exacerbates the pressures, the agency added that globally, nine per cent of the freshwater resources are withdrawn, 70 per cent of this by irrigated agriculture; while agriculture and land use changes like deforestation contribute to more than 30 per cent of total global greenhouse gas emissions.
According to the global food body, across the world, the agri-food system accounts for nearly 30 per cent of end-user available energy while overfishing and poor management contribute to declining numbers of fish with some 30 per cent of marine fish stocks now considered overexploited. (...)
