Book excerpt: More than a decade has passed since the publication of the series entitled Social Analysis of Agriculture and Rural Investment Projects, which comprises three complementary manuals – the Manager’s, Practitioner’s and Field guides. During this time, conflict, climate change and economic downturns have been driving up poverty, hunger, and socioeconomic inequalities, reducing the resilience of agrifood systems. In response, the FAO Investment Centre has updated the Social Analysis guides to address the evolving and volatile rural transformation context, providing programme managers, practitioners and field workers with a set of enhanced tools for the design, implementation and evaluation of inclusive investments in agrifood systems. Today’s investments must prioritize more demand-driven, people-centred, culturally sensitive and locally owned sustainable approaches, with increased attention to reducing gender and other inequalities. Operationalizing these principles contributes to FAO’s and financing agencies’ objectives of ending poverty, improving food security and nutrition, and reducing inequalities. The goal of the updated guides is to support investments that contribute to inclusive, resilient and sustainable agrifood systems, aligned with the outcomes of the UN Food Systems Summit, the Sustainable Development Goals (SDGs), and the core principle of leaving no one behind. This publication is part of the Investment Toolkits series under the FAO Investment Centre's Knowledge for Investment (K4I) series. The contents of this publication have been developed into three e-learning courses, which are accessible for free through the FAO E-learning Academy.
