Despite 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.

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 adopt--and what strategies should they use--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.

Shaping Change presents the current state of play of Extension, and its role in Natural Resource Management and commercial agricultural industry for the Australasia-Pacific region. It is a prime text for under- and post-graduate students, and an essential reference manual for new and experienced Extension professionals alike, be they engaged exclusively in environmental conservation, agriclutural productivity, or more commonly both.
