Climate change is a contributing factor, but not the only one.  In particular, we must reconsider our agricultural practices and how we manage our water resources.  Agriculture and the raising of livestock account for 70 per cent of freshwater use and as much as 80 per cent of deforestation.  Growing demand for crops for animal feed and biofuels will put further pressure on these scarce resources if not managed sustainably.  

Current global consumption and production patterns are unsustainable.  The consequences will include further global food crises, such as we saw in 2008, and continued desertification, land degradation and periods of drought.  As usual, the poor will be the first victims and the last to recover. 

The recently concluded seventeenth session of the Commission on Sustainable Development stressed that desertification and land degradation are global problems that require a global response.  In December, world leaders can provide such a response when they meet in Copenhagen to seal a deal on climate change.  A comprehensive and equitable agreement to slow down global warming must also help developing countries to adapt to the impacts that are already under way.  In particular, it must provide adequate and predictable financing to support improved land management, more efficient water use and sustainable agriculture. 

On this World Day to Combat Desertification, let us recognize the security risks of letting desertification advance unchecked.  Let us also recognize that by combating climate change we can help to reverse desertification, increase agricultural productivity, alleviate poverty and enhance global security.
