Innovative research approaches for sustainable livestock production and poverty reduction in the developing world por Kristjanson, Patricia M.

“…The ‘multifunctionality’ of livestock for the poor, coupled with the severe institutional, policy and governance constraints found in most developing countries, means that how livestock researchers engage with partners, and how they do and communicate their science, matter even more than they do in Europe or North America. There are a wide range of approaches and tools available that can help enhance both the effectiveness (impact) and efficiency of taking an innovation systems approach. …”
