There are thousands of successful experiences of localized enhanced pest and weed management, water efficiency and biodiversity, including stories of highly successful innovation in the most challenging circumstances characterized by a poor natural resource base and widespread poverty (World Bank, 2007a, 2008c, Thapa and Broomhead, 2010, Spielman and Pandya-Lorch, 2009, Africare, Oxfam America and WWF-ICRISAT Project, 2010, Pretty and others, 2006). While indigenous female workers have experience in the management of biodiversity and traditional knowledge for sustainable agriculture, poor access to land, inputs and credit has often prevented the expansion of that successful experience (World Bank, 2009). The integrated pest management (IPM) approach, proliferating Farm Field Schools and the System of Rice Intensification (SRI) are good examples of creative innovation that achieved large-scale impacts through highly effective collaboration among multiple stakeholders (see box III.l). The projects evaluated encompassed 3 per cent of cultivated area in developing countries.
