The development of sustainable agricultural systems is an imperative aspect of any country, but particularly in the context of developing countries. Lack of progress in these initiatives can have negative effects on the nation as a whole. Agricultural Development and Food Security in Developing Nations is a pivotal reference source for the latest scholarly material on promoting advancements in agricultural systems and food security in developing economies. Highlighting impacts on citizens, as well as on political and social environments of a country, this book is ideally designed for students, professionals, policy makers, researchers, and practitioners interested in recent developments in the areas of agriculture.

Agricultural extension provides the critical connection from agricultural innovation and discovery to durable improvements at scale, as farmers and other actors in the rural economy learn, adapt, and innovate with new technologies and practices. However, lack of capacity and performance of agricultural extension in lower- and middle-income countries is an ongoing concern. Research on agricultural extension and advisory services (in short, extension) has been an integral part of the CGIAR Research Program on Policies, Institutions, and Markets (PIM) since its inception. This brief synthesizes key findings from research funded by and linked to PIM from 2012 to 2021, presenting lessons learned and a vision for the future of extension. A list of all PIM-related extension and advisory services research is provided at the end. Designing and implementing effective provision of extension is complex, and efforts to strengthen extension services often fall into a trap of adopting “best practice” blueprint approaches that are not well-tailored to local conditions. An expansive literature examines the promises and pitfalls of common approaches, including training-and-visit extension systems, farmer field schools, and many others (Anderson and Feder 2004; Anderson et al. 2006; Waddington and White 2014; Scoones and Thompson 2009). To understand extension systems and build evidence for what works and where, the “best-fit” framework, a widely recognized approach developed by Birner and colleagues (2009) and adapted by Davis and Spielman (2017), offers a simple impact chain approach (Figure 1). The framework focuses on a defined set of extension service characteristics that affect performance: governance structures and funding; organizational and management capacities and cultures; methods; and community engagement — all of which are subject to external factors such as the policy environment, agroecological conditions, and farming-system heterogeneity. To enhance extension performance and, ultimately, a wide range of outcomes and impacts, new and innovative interventions can be applied and adapted within this set of extension characteristics.

The Million Farmers School (MFS) is an innovative extension program initiated by the Department of Agriculture in the state of Uttar Pradesh, India, in 2017. Twice in a year, the department deploys its entire extension machinery to organize nearly 15,000 training programs for about a million farmers across all districts of the state. Unlike traditional extension services, MFS integrates various facets of agricultural knowledge into a packaged product and delivers through village-level trainings where printed material on the topics of training are also distributed among participants. This study presents early findings of a process evaluation, involving assessments of program design, implementation strategies, and estimation of benefits from program participation. In addition to consultation with public officials and community organizations, a state-level representative survey was conducted on a sample of both participating and non-participating households. The early results based on matching and instrumental variable methods—suggest that knowledge outcomes are significantly better among participants vis-à-vis non-participants. The results are robust to different model specifications. The study also qualitatively assesses various aspects of the program’s design and implementation, highlighting the constraints and challenges it faces and offers implementation advice for greater efficacy in its future course.

This book on Improving Agricultural Extension: a Reference Manual offers a critical review and inventory-analysis of the "State of the Art" in agricultural extension theory and best practices written by internationally known agricultural extension practitioners, educators and scholars. A total of 38 authors from 15 countries contributed to the 23 chapters of this book and thus they provided broad international perspectives, covering both theory and practice, as well as micro and macro issues related to agricultural extension. It is the third edition of a classic reference manual on agricultural extension published by the Food and Agriculture Organization (FAO) of the United Nations. Aimed at agricultural extension planners, managers, trainers, educators, and field practitioners, this book could be useful in improving the quality of agricultural extension and in generating new ideas and methods for increasing further the cost-effectiveness of agricultural extension programmes. It provides many sound and practical suggestions for developing and improving the conceptual, technical, and operational methods and tools in order to strategically plan, efficently manage, and scientifically evaluate a problem-solving, demand-driven and needs-based agricultural extension programmes.

The paper analyzes several aspects of the operation and effects of the T & V extension system. Specific questions related to the supply of, and demand for, extension agents (VEW) visits, the presence or absence of farm size bias in VEW visits, seasonal and longer-term variations in the pattern of VEW visits, the relative importance of the VEW as a source of information to farmers, and the crop yields obtained by farmers in relation to their main sources of agricultural advice are addressed in detail. The paper draws the following main conclusions. Most (85 percent) contact farmers are visited regularly, and the majority of noncontact farmers also have some interaction with VEWs, suggesting that the supply of extension services is adequate. VEWs appear to be more active in the dry season than in the rainy season, which may be attributable to an emphasis on irrigated crop technology. As experience with the T & V system increases, contact farmers appear to receive fewer visits from VEWs, but visits to noncontact farmers increase. VEWs play a more important role as a disseminators of information in areas operating the T & V system than in areas relying on the older community development system of extension.

This publication reviews key trends and policy developments aimed at reforming agricultural extension systems, in order to address issues of food security, poverty alleviation and rural sustainable development. It highlights the importance of the public sector in promoting rural development through extension and communication. A number of recommendations are made for developing countries, which seek to encourage institutional reforms and dialogue among diverse providers of extension services, all aimed at advancing livelihoods and income generation of poor rural people.
