Available in PDF, EPUB and Kindle. Book excerpt: Improved technologies are increasingly promoted to farmers in sub-Saharan-African countries to address low agricultural productivity in their staple crops. There is, however, a lack of evidence on how adoption affects farmers’ labor use and profitability at the farm level, as well as the importance gender roles play, all essential drivers for the successful up-scaling of the use of the improved technologies. This paper analyses the labor and profitability impact of the recently introduced row planting technology in teff production in Ethiopia. Based on agronomic evidence in experimental settings, the Government of Ethiopia has focused extension efforts on promoting the widespread uptake of row planting to address low teff yields, replacing the traditional broadcasting method of plant teff. Using an innovative Randomized Controlled Trial set-up, we show that the implementation of row planting at the farm level significantly increases total labor use, but not teff yields, relative to broadcast planting, resulting in a substantial drop in labor productivity when adopting row planting. Moreover, the implementation of row planting has important consequences for inter- and intra-household labor allocation, with relatively more use of non-family labor. The adoption of row planting was further found not to be profitable for farmers in the first year of the promotion campaign, seemingly explaining the limited success in up-scaling the adoption of the technology by farmers in the second year of the program.

This book was released on 2018-07-19 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considerable poverty and food insecurity in Ethiopia, combined with the overwhelming majority of Ethiopians who depend on agriculture for their livelihoods, make agricultural transformation a crucial development goal for the country. One promising improvement is to increase production of teff, the calorie- and nutrient-rich but low-yielding staple. The Economics of Teff: Exploring Ethiopia’s Biggest Cash Crop examines key aspects of teff production, marketing, and consumption, with a focus on opportunities for and challenges to further growth. The authors identify ways to realize teff’s potential, including improving productivity and resilience, selecting and scaling up new technologies, establishing distribution systems adapted to different areas’ needs, managing labor demand and postharvest operations, and increasing access to larger and more diverse markets. The book’s analysis and policy conclusions should be useful to policy makers, researchers, and others concerned with Ethiopia’s economic development.

Book excerpt: Adoption of yield - increasing technologies is seen as a key driver to increase agricultural production in Sub-Saharan Africa. There is, however, a lack of empirical evidence on the impact of programs aiming to scale-up the adoption of improved technologies from research settings to the farm level. To fill this gap, this paper assesses the impact of the promotion of a new agricultural technology, i.e. row planting at reduced seed rate, on farmers' teff yields in Ethiopia. The results of a randomized control trial show that the program to scale-up row planting on average has a positive effect on teff yield. Depending on the measure of yield used, we find increases between 2 percent - but not statistically significant - and 22 percent. These findings are in contrast with larger yield increases found on village demonstration plots and in more controlled settings, as well as with the yield increase expected by teff farmers. The differences seemingly are linked to problems in implementation of the program and of its recommendations, methodological issues, and likely over-optimism on the potential of row planting in real farm settings.

Book excerpt: This study analyzes the perceptions, impacts, and rewards of farmers who adopted row planting for the production of teff as a result of being exposed to a technology promotion campaign for row planting of teff in the Oromia region of Ethiopia. Our three main findings are as follows. First, despite a positive attitude towards row planting (and reduced seed rates in general) and a belief in the (large) yield increasing potential of row planting, exposed farmers only put a relatively small part of their plots aside for row planting in the next planting season. This indicates concerns with the additional labor requirement and possibly the need for more knowledge and experience with the new technology. Second, by implementing row planting, farmers experienced an increase in teff yield in the first year of implementation, but there was also a substantial increase in labor input requirements. A cost-benefit analysis shows that the increase in teff yield outweighs the cost of the extra labor in the first year of adoption when yields increase by 8 percent or more. Third, suitable mechanization for row planting would change the cost-benefit picture significantly and is shown to be an investment with possible high returns.

Book excerpt: Scientific Essay from the year 2021 in the subject Agrarian Studies, grade: 1, , course: Agriculture, language: English, abstract: Teff is a major staple cereal crop in Ethiopia. The need for its production as a staple food is increasing from year to year; however, its productivity is limited, amongst others, by the use of improper sowing methods and inappropriate seed rates. These effects were examined in this present study. Row planting and optimizing seed rate should be in place to increase the productivity of the crop. A field experiment was conducted at Wolaita Sodo Agricultural College Farm, during the 2018/19 main cropping season under rain-fed condition, with the objective of evaluating the response of teff to seeding rates and sowing methods on phenology, growth, yield components and yield of teff. Factorial combinations of two sowing methods (Row and broadcast) and five seeding rates were laid out in a randomized complete block design with three replications. Data related to phenology, growth, yield and yield attributes, were collected and analyzed using Gestate software. Plant parameters such as days to panicle emergence, lodging %, number of total and effect tillers per plant and grain yield were significantly affected by the interaction effect of sowing methods and seed rates. Plots sown with low seeding rate combined with row planting gave high grain yield. Therefore, using treatment combinations of seeding rate of 2.5 kg ha−1 together with the row planting can be advised for teff production in the study area. However, repeated experiment over different soil type, seasons and locations necessitates for conclusive recommendation.

This book was released on with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The perception of Ethiopia projected in the media is often one of chronic poverty and hunger, but this bleak assessment does not accurately reflect most of the country today. Ethiopia encompasses a wide variety of agroecologies and peoples. Its agriculture sector, economy, and food security status are equally complex. In fact, since 2001 the per capita income in certain rural areas has risen by more than 50 percent, and crop yields and availability have also increased. Higher investments in roads and mobile phone technology have led to improved infrastructure and thereby greater access to markets, commodities, services, and information. In Food and Agriculture in Ethiopia: Progress and Policy Challenges, Paul Dorosh and Shahidur Rashid, along with other experts, tell the story of Ethiopia's political, economic, and agricultural transformation. The book is designed to provide empirical evidence to shed light on the complexities of agricultural and food policy in today's Ethiopia, highlight major policies and interventions of the past decade, and provide insights into building resilience to natural disasters and food crises. It examines the key issues, constraints, and opportunities that are likely to shape a food-secure future in Ethiopia, focusing on land quality, crop production, adoption of high-quality seed and fertilizer, and household income. Students, researchers, policy analysts, and decisionmakers will find this book a useful overview of Ethiopia's political, economic, and agricultural transformation as well as a resource for major food policy issues in Ethiopia.

Book excerpt: Ethiopia has experienced impressive agricultural growth and poverty reduction, stemming in part from substantial public investments in agriculture. Yet, the agriculture sector now faces increasing land and water constraints along with other challenges to growth. Ethiopia’s Agrifood System: Past Trends, Present Challenges, and Future Scenarios presents a forward-looking analysis of Ethiopia’s agrifood system in the context of a rapidly changing economy. Growth in the agriculture sector remains essential to continued poverty reduction in Ethiopia and will depend on sustained investment in the agrifood system, especially private sector investment. Many of the policies for a successful agricultural and rural development strategy for Ethiopia are relevant for other African countries, as well. Ethiopia’s Agrifood System should be a valuable resource for policymakers, development specialists, and others concerned with economic development in Africa south of the Sahara.

This book was released on 2016-09-27 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use qualitative and quantitative information from a number of datasets to study the adoption patterns and labor productivity impacts of herbicide use in Ethiopia. We find a four-fold increase in the value of herbicides imported into Ethiopia over the last decade, primarily by the private-sector. Adoption of herbicides by smallholders has grown rapidly over this period, with the application of herbicides on cereals doubling to more than a quarter of the area under cereals between 2004 and 2014. Relying on unique data from a large-scale survey of producers of teff, the most widely grown cereal in Ethiopia, we find significant positive labor productivity effects of herbicide use of between 9 and 18 percent. We show that the adoption of herbicides is strongly related to proximity to urban centers, levels of local rural wages, and access to markets. All these factors have changed significantly over the last decade in Ethiopia, explaining the rapid take-off in herbicide adoption. The significant increase in herbicide use in Ethiopia has important implications for rural labor markets, potential environmental and health considerations, and capacity development for the design and effective implementation of regulatory policies on herbicides .

Available in PDF, EPUB and Kindle. Book excerpt: For thousands of years, Ethiopia has depended on its smallholding farmers to provide the bulk of its food needs. But now, such farmers find themselves under threat from environmental degradation, climate change and declining productivity. As a result, smallholder agriculture has increasingly become subsistence-oriented, with many of these farmers trapped in a cycle of poverty. Smallholders have long been marginalised by mainstream development policies, and only more recently has their crucial importance been recognised for addressing rural poverty through agricultural reform. This collection, written by leading Ethiopian scholars, explores the scope and impact of Ethiopia’s policy reforms over the past two decades on the smallholder sector. Focusing on the Lake Tana basin in northwestern Ethiopia, an area with untapped potential for growth, the contributors argue that any effective policy will need to go beyond agriculture to consider the role of health, nutrition and local food customs, as well as including increased safeguards for smallholder’s land rights. They in turn show that smallholders represent a vitally overlooked component of development strategy, not only in Ethiopia but across the global South.

This book was released on 2021-12-28 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of information and communications technologies (ICTs) to address a wide array of development issues has gained considerable attention among governments, practitioners, and researchers in recent years (Lwoga and Sangeda 2019). While early studies focused on mobile phones and text messaging, attention is quickly shifting to other media, including video. Many studies on the use of video as a medium explore how increased access and consumption of information can lead to behavior changes that ultimately result in welfare-improving outcomes. This study explores whether video-mediated extension leads to the increased, sustained uptake of productivity-enhancing agricultural technologies and practices by small-scale farmers. Over the two-year period of 2017–2018, the Government of Ethiopia and Digital Green conducted the large-scale rollout of a video-mediated extension approach. We examine the impact of this rollout on a range of outcome indicators, including whether targeting the video-mediated approach to both spouses of a household was more effective than targeting the (typically male) household head alone. Our main outcomes of interest include farmer uptake of the subject technologies and the yield gains resulting from these technologies. Our study provides insights into the mechanisms behind the observed effects and an analysis of the approach’s cost effectiveness. Our results demonstrate that the video-mediated extension approach led to increases in farmer uptake of improved agricultural technologies and practices. In the first year of the experiment, we find an overall 6 percentage point increase in technology uptake, which translates into a 10 percent increase over the mean of the control group. An analysis of uptake by type of technology shows that the video-mediated approach resulted in an increase of 13, 20, and 15 percent over control group means for row planting, precise seeding rate, and urea top/side dressing, respectively. These results endure in the second year of the experiment, pointing to farmers’ effective uptake of the technology beyond a mere trial in one production season. Upon exploring the mechanisms that explain these adoption effects, we find that the video-mediated extension approach led to an increase in extension reach, with a 35 percent increase in farmers’ attendance at extension sessions (likely due to interest in the video medium). Among farmers assigned to the video-mediated extension approach, we also find a higher level of technical understanding of focal agricultural technologies and practices. While our results suggest greater participation and knowledge gains among (typically female) spouses who also participated in the video-mediated extension approach, we do not find clear evidence that targeting both spouses led to higher rates of technology uptake.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ethiopia's major staple crop is Teff (Eragrostisteff). Teff is one of the most important crops for farm income and food security in Ethiopia. Despite the importance of teff in Ethiopia, yields are remarkably low. Low yield due to low adoption of improved agricultural technologies is believed to be the main factor. Awareness is endogenous to the decision to adopt; thus, awareness and adoption are modelled jointly to allow us to interpret awareness as a potential policy variable which can be used to influence the probability of adoption. Therefore, this study was carried out to assess the awareness of improved cultivation and post-harvest management practices of teff by smallholder teff farmers. The study used both quantitative and qualitative research approaches. Cross sectional survey research design was employed to collect data. Among the 19 districts in the West Shoa zone, Chaliyadistrict was purposively selected because this district has 6815 ha of land under teff under cultivation, out of which only 46 ha are under improved practices. The number of respondents to be selected from each randomly selected eight villages was determined based on Probability Proportional to Size (PPS). The respondents (239) were selected from the eight villages by using random sampling technique. The data were collected using semi-structured interview schedule, key informant interviews and focus group discussions. The collected data were coded, tabulated and analysed using descriptive statistical tests.In this research, it was found that the awareness on mechanical thresher, line sowing, less seed rate and transplanting was less among the respondents, which was a major constraint in adoption. The awareness about the benefits of row planting, transplanting and use of mechanical thresher was low among the respondents. Therefore, the extension agency should put forth more efforts to create awareness on these technologies and its benefits by employing effective and suitable communication methods as the awareness was low on these technologies.

Book excerpt: This book investigates if and how agricultural market structures and farm constraints affect the development of dynamic food and cash crop sectors and whether these sectors can contribute to economic transformation and poverty reduction in Africa. The authors map the current cash and food crops supply chains in six African countries, characterizing their markets structures and domestic competition policies. At the farm level, the book studies the constraints faced by small holders to increase productivity and break out of a vicious cycle in which low productivity exacerbates vulnerability to poverty. In a series of micro case studies, the project explores how cooperatives and institutions may help overcome these constraints. This book will appeal to scholars and policy makers seeking instruments to promote increased agriculture productivity, resolve food security issues, and promote agribusiness by diversifying exports and increasing trade and competitiveness.

Book excerpt: The dramatic increases in food prices experienced over the last four years, and their effects of hunger and food insecurity, as well as human-induced climate change and its implications for agriculture, food production and food security, are key topics within the field of agronomy and agricultural research. Contested Agronomy addresses these issues by exploring key developments since the mid-1970s, focusing in particular on the emergence of the neoliberal project and the rise of the participation and environmental agendas, taking into consideration how these have had profound impacts on the practice of agronomic research in the developing world especially over the last four decades. This book explores, through a series of case studies, the basis for a much needed ‘political agronomy’ analysis that highlights the impacts of problem framing and narratives, historical disjunctures, epistemic communities and the increasing pressure to demonstrate ‘success’ on both agricultural research and the farmers, processors and consumers it is meant to serve. Whilst being a fascinating and thought-provoking read for professionals in the Agriculture and Environmental sciences, it will also appeal to students and researchers in agricultural policy, development studies, geography, public administration, rural sociology, and science and technology studies.

Book excerpt: As the world’s population rises to an expected ten billion in the next few generations, the challenges of feeding humanity and maintaining an ecological balance will dramatically increase. Today we rely on just four crops for 80 percent of all consumed calories: wheat, rice, corn, and soybeans. Indeed, reliance on these four crops may also mean we are one global plant disease outbreak away from major famine. In this revolutionary and controversial book, Jonathan Gressel argues that alternative plant crops lack the genetic diversity necessary for wider domestication and that even the Big Four have reached a “genetic glass ceiling”: no matter how much they are bred, there is simply not enough genetic diversity available to significantly improve their agricultural value. Gressel points the way through the glass ceiling by advocating transgenics—a technique where genes from one species are transferred to another. He maintains that with simple safeguards the technique is a safe solution to the genetic glass ceiling conundrum. Analyzing alternative crops—including palm oil, papaya, buckwheat, tef, and sorghum—Gressel demonstrates how gene manipulation could enhance their potential for widespread domestication and reduce our dependency on the Big Four. He also describes a number of ecological benefits that could be derived with the aid of transgenics. A compelling synthesis of ideas from agronomy, medicine, breeding, physiology, population genetics, molecular biology, and biotechnology, Genetic Glass Ceilings presents transgenics as an inevitable and desperately necessary approach to securing and diversifying the world's food supply.
