As part of a Darwin Initiative project awarded in March of this year http://www.nhm.ac.uk/natureplus/blogs/tropicalbotanyresearcher/2013/05/02/darwin-initiative-grant-to-work-in-the-bolivian-amazon a team comprising foresters from the Bolivian NGO Herencia http://www.herencia.org.bo/ and botanists from the Tropical America Team at Kew are seeking to reduce pressure on the tropical forests of the Bolivian Amazon.

We are aiming to do so by encouraging the establishment permanent agriculture (permaculture) on degraded cattle pasture and disused slash and burn (chaco) sites through a series of demonstration plots established in partnership with four rural communities. Our aim is to use trees of the Inga genus of the legume family (beans, pulses, tamarind) to capture and restore soil fertility over a period of 18 months and then pollard the trees so that crops can be grown between the rows. Inga is the ideal genus to do so as it thrives and grows quickly, up to 6 m in two years, in the very acidic, poor degraded soils of abandoned chaco and cattle pasture. It captures and rehabilitates sites by shading out weeds, enriching the soil with its specialized roots and abundant leaf litter and attracting a host of biological control agents to protect the crops.
