The first peer-reviewed publication of the Systemwide Livestock Programme (SLP) crop residue project is now on-line in Field Crops Research. This paper describes the options and challenges of Conservation Agriculture (CA) in mixed systems by comparing 12 study sites in 9 countries across Sub-Saharan Africa and South Asia. Results illustrate that “despite its potential benefit for smallholder farmers across the density gradient, the introduction of CA-based mulching practices appears potentially easier in sites where biomass production is high enough to fulfil existing demands for feed and fuel. In sites with relatively high feed and fuel pressure, the eventual introduction of CA needs complementary research and development efforts to increase biomass production and/or develop alternative sources to alleviate the opportunity costs of leaving some crop residues as mulch”.

This is the result of collaborative research of different CGIAR centers and other institutions: SLP, ILRI, CIMMYT, ICRISAT, IITA, CIP and Wageningen University.
