This study was possible with BSAS travel award and the BBSRC.Grateful thanks to the CLEANED model team at CIAT Kenya and in specific project areas to ICIPE Nairobi, Sokoine University of Agriculture, ILRI, all administration, finance and logistics staff of CIAT. Recognition is paid to the Tanzanian and Maasai producers who so willingly  provided their time, expertise, crops and livestock.
