"Many organizations working in research and development look on the private sector as donors," says Tony Simons, Director General of the World Agroforestry Centre, "but for us the relationship is about more than finance. We believe we can help private sector businesses to become more sustainable and environmentally aware."You expect to see stories about Mars, Inc., Unilever, Syngenta and Danone in the business pages of newspapers and magazines; but they also feature in this annual report. They are among the growing list of companies which have developed partnerships with the World Agroforestry Centre.In 2014, Ramni Jamnadass, head of research on Tree Diversity, Domestication and Delivery, co-authored a major review of public-private partnerships in agroforestry. Published as a chapter in the Encyclopaedia of Agriculture and Food Systems, the study showed that public private partnerships can have a substantial impact on the livelihoods of smallholder farmers and marginalized groups in developing countries.
