A new report by the United Nations has added credence to the view that sustainable grazing and pasture management can significantly contribute to the fight against global climate change. Entitled, "Review on Evidence on Dryland Pastoral Systems and Climate Change," this paper offers much-needed discussion about the role that pasture can play in our efforts to mitigate carbon emissions and preserve these important carbon-sequestering ecosystems. Pasturelands are under increasing pressure from development, salinization, overgrazing and transition to annual cropping for grain production (much of which goes to livestock feed). However, if properly managed they represent a carbon sink that could be even greater than forests.
