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.

Since their inception in 1862, the U.S. land grant colleges have evolved to become the training ground for the nation's and the world's agriculturists. In this book, the committee examines the future of the colleges of agriculture in light of changing national priorities for the agricultural, food, and natural resource system. The effects of federal funding constraints also are examined, as are opportunities for growth presented by developments in science. The committee's preceding volume, Colleges of Agriculture at the Land Grant Universities: A Profile, is a compilation of the data that helped formulate the specific questions to be addressed. Colleges of Agriculture at the Land Grant Univerisities: Public Service and Public Policy is the deliberative report, rating conclusions and recommendations for institutional innovation and public policy. It addresses these and other questions: What education mission should colleges of agriculture adoptâ€"and what strategies should they useâ€"in light of significant changes in the agricultural complex? Research in agriculture is expected to respond to consumer demands, environmental concerns, world population growth, and increasing pressure on agricultural lands. Is the century-old structure of land grant university-based research up to the task? What is the role of extension in light of today's smaller farming communities and larger farming conglomerates? This volume is the culmination of a landmark evaluation of land grant colleges of agriculture, an American institution. This document will be of value to policymakers, administrators, and others involved in agricultural science and education.

Distress migration is particularly acute among rural youth. Agriculture and rural development are central to the rate of rural out-migration to urban areas. The agricultural sector needs to engage youth in order to increase global food production. In doing so, agricultural transformation can balance out-migration from rural areas and thus contribute to stable growth. This document presents the conceptual framework for distress migration of rural youth. The framework focuses on the migration of rural youth (aged 15–24), who account for a large proportion of migrants and are a particularly vulnerable group. The framework comprises three sections: 1. Analysis of the main factors determining the propensity of rural youth to migrate; 2. Assessment of the likely impacts of distress migration of rural youth in terms of rural development for local areas of origin; 3. Illustration of the most promising policies and programmes to reduce distress migration of rural youth and maximize its dev elopmental benefits for the communities of origin.
