This publication describes FAO’s engagement in South-South and triangular cooperation (SSTC) in support of efforts to boost agricultural productivity, enhance food and nutrition security and alleviate poverty in developing countries worldwide. More than 40 years ago, FAO first established a focal point to promote, coordinate and integrate technical cooperation among developing countries in all activities. This followed the endorsement by the United Nations General Assembly of the Buenos Aires Plan of Action for Promoting and Implementing Technical Cooperation among Developing Countries (BAPA). Now, following the BAPA+40 conference, the Organization has a fullyfledged technical division on SSTC, is in the process of revising its SSTC strategy and has more than 15 formal SSTC partnerships in place. This work has served to demonstrate the power of SSTC to deliver sustainable solutions to vulnerable populations in the global South and the contribution that SSTC can make to achieving the Sustainable Development Goals, especially SDG 1 (No poverty) and SDG 2 (Zero hunger).
