We’ve blogged briefly about how vast areas of the Sahel, far from degenerating, are actually experiencing something of an agricultural rebirth, thanks in some small measure to tree-planting. ((Skeptics may point to rainfall cycles; I’m not sure it matters.)) A post from Oxfam America summarizes some of those efforts, and explains that Oxfam brought some of the people responsible — elevated to eco-hero status — to Washington DC “for discussions with US legislators about local solutions to food insecurity and climate change.” We haven’t noticed any reports of those discussions, but are happy to draw attention to the high impact of local solutions to local problems, especially when they make use of agricultural biodiversity. Thanks to CAS-IP, which has an expanded gloss on Oxfam’s efforts.
