Reuters news service reported yesterday that desertification is affecting about a fourth of India’s land.  Agricultural lands are becoming degraded and threatening food security in this highly populated country.  The main causes of the desertification are overgrazing and heavy land use coupled with changes in rainfall over time.  Some of the areas most affected are the regions which grow cotton and rapeseed.  This could affect global markets for these crops in the future.  For more information, click here.
