Science solutions? Not just one crop species Not just for grain Farmers buy limited inputs Manure has to come from livestock Livestock have to be fed Feed comes from cropland Crop varieties - more and better quality feed Kraaling not always practical!
Compost pits are good……….but - transport to distant fields? - complementarity with inorganic fertilizer? In Burkina Faso: - begin with farmer evaluation of feeding and compost options -potential to dual purpose varieties and crop patterns - excellent Danish partners, with expertise in group dynamics
In Ghana: - small ruminant feeding in wet season - a new challenge? - begin with farmer evaluation of feeding and compost options - opportunities to introduce dual purpose varieties etc - outstanding partnerships at grass roots level
Keep the holistic balance - all aspects are important, the aim is SUSTAINABLE improvements in productivity - so the highest production (especially of grain) is not always the “best” and the “fit” into the social and economic circumstances also needs to be considered
Multi-site investigations demand flexibility according to farming system, BUT don’t get away from the basic principles. Have a protocol and database structure
