Countries in the South offer a myriad of development solutions – knowledge, experiences, good practices, innovative policies, technologies, and resources – that have proven cost-effective and have huge potential to be up-scaled for the benefit of others. This Guide starts from the premise that South-South Cooperation (SSC) is playing a greater role than ever before in the international development landscape. Innovation in the South is generating new tools and partnerships for tackling issues of food insecurity, poverty and sustainable agriculture. In addition, Triangular Cooperation is a growing phenomenon, whereby a third party, usually an Organisation for Economic Co-operation and Development (OECD) country or multilateral organization, provides resources to facilitate SSC.
