DOWNLOAD EBOOKAgricultural 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.

DOWNLOAD EBOOKDespite a rapidly growing enthusiasm around applications of information and communications technologies (ICTs) to smallholder agriculture in developing countries, there are still many questions on the effectiveness of ICT-based approaches. This study assesses the effects of videomediated agricultural extension service provision on farmers’ knowledge and adoption of improved agricultural technologies and practices in Ethiopia. The study focuses on a program piloted by the Government of Ethiopia and Digital Green and poses three questions. First, to what extent does video-mediated extension lead to increased uptake of improved agricultural technologies and practices by smallholder farmers? Second, is video-mediated extension targeted at both spouses of the household more effective than when only targeted at the (typically male) household head? Third, how cost-effective is a video-mediated approach to extension provision? The study explores these questions with a randomized controlled trial designed to evaluate the video-mediated approach as applied to three priority crops (teff, wheat, maize) and three technologies (row planting, precise seeding rates, and urea dressing). The trial was implemented in 347 kebeles (village clusters) during the 2017 meher (rainy) season in Ethiopia’s four most agriculturally important regional states. Analysis of data from our surveys of 2,422 households and 896 extension agents indicates that the video-mediated approach is more effective than the conventional approach in achieving several key outcomes. Specifically, we find that videomediated extension reaches a wider audience than the conventional approach and leads to higher levels of agricultural knowledge and uptake of technologies in those kebeles randomly assigned to the program. While our results do point to greater participation and greater knowledge of female spouses in kebeles where both male and female spouses were targeted by the program, we do not find clear evidence that the more inclusive approach translated into higher uptake of the subject technologies and practices. Finally, we find that the video-mediated approach becomes less costly as the scale of operation increases.

DOWNLOAD EBOOKKnowledge generation and transfer mechanisms are being transformed in important and controversial ways. Investment in research and development has increased in response to recognition that scientific productivity is tightly connected to economic dynamism. Patent protection has been expanded in order to stimulate higher levels of private investment. Intellectual property rights held by public organizations and researchers are now increasingly transferred to private organizations to accelerate the diffusion and enhance the value of knowledge produced by public agencies and universities. Additionally, new institutions such as university offices of technology transfer, venture capital markets, and a variety of consortia in knowledge-intensive industries are being established throughout the United States and in other parts of the world. These changes have led to a repositioning of the state in systems of innovation and an increase in the proprietary character of technical information. The purpose of this book is to review and analyze i) contemporary transitions in agricultural knowledge generation and extension arrangements from an empirical perspective, and ii) emerging and contradictory perspectives as to how knowledge systems can be assessed effectively. The authors aim to provide the reader with a better understanding of the implications of new biotechnologies and new intellectual property rights regimes on public-private relations in science, the extent to which benefits from scientific knowledge are being appropriated by private sector actors, the diversity and possible outcomes of privatization initiatives in extension, and prospects for public goods production and ecological sustainability given contemporary trends. The book presents contrasting views on the degree of complementarity and substitution between private and public sector investments in research and extension. Recognizing that the labels `public' and `private' are incomplete and at times misleading descriptions of the structure and function of coordinating bodies in social systems, the analyses highlight ways in which public and private spaces and modes of functioning combine. In addition to illustrating a broad range of analytic methodologies useful for studying organizational questions in knowledge systems, the authors identify the implications of a range of past and potential institutional innovations.

DOWNLOAD EBOOKAbstract: May 1999 - The agriculture sector must nearly double biological yields on existing farmland to meet food needs, which will double in the next quarter century. A sustainable approach to providing agricultural extension services in developing countries-minimal external inputs, a systems orientation, pluralism, and arrangements that take advantage of the best incentives for farmers and extension service providers-will release the local knowledge, resources, common sense, and organizing ability of rural people. Is agricultural extension in developing countries up to the task of providing the information, ideas, and organization needed to meet food needs? What role should governments play in implementing or facilitating extension services? Roughly 80 percent of the world's extension is publicly funded and delivered by civil servants, providing a range of services to the farming population, commercial producers, and disadvantaged target groups. Budgetary constraints and concerns about performance create pressure to show the payoff on investment in extension and to explore alternatives to publicly providing it. Feder, Willett, and Zijp analyze the challenges facing policymakers who must decide what role governments should play in implementing or facilitating extension services. Focusing on developing country experience, they identify generic challenges that make it difficult to organize extension: The magnitude of the task; Dependence on wider policy and other agency functions; Problems in identifying the cause and effect needed to enable accountability and to get political support and funding; Liability for public service functions beyond the transfer of agricultural knowledge and information; Fiscal sustainability; Inadequate interaction with knowledge generators. Feder, Willett, and Zijp show how various extension approaches were developed in attempts to overcome the challenges of extension: Improving extension management; Decentralizing; Focusing on single commodities; Providing fee-for-service public extension services; Establishing institutional pluralism; Empowering people by using participatory approaches; Using appropriate media. Each of the approaches has weaknesses and strengths, and in their analysis the authors identify the ingredients that show promise. Rural people know when something is relevant and effective. The aspects of agricultural extension services that tend to be inherently low cost and build reciprocal, mutually trusting relationships are those most likely to produce commitment, accountability, political support, fiscal sustainability, and the kinds of effective interaction that generate knowledge. This paper-a joint product of Rural Development, Development Research Group, and the Rural Development Department-is part of a larger effort in the Bank to identify institutional and policy reforms needed to promote sustainable and equitable rural development.
