DOWNLOAD EBOOK →Roots and tubers are considered as the most important food crops after cereals and contribute significantly to sustainable development, income generation and food security especially in the tropical regions. The perishable nature of roots and tubers demands appropriate storage conditions at different stages starting from farmers to its final consumers. Because of their highly perishable nature, search for efficient and better methods of preservation/processing have been continuing alongside the developments in different arena. This book covers the processing and technological aspects of root and tuber foods, detailing the production and processing of roots and tubers such as taro, cassava, sweet potato, yam and elephant foot yam. Featuring chapters on anatomy, taxonomy and physiology, molecular and biochemical characterization, GAP, GMP, HACCP, Storage techniques, as well as the latest technological interventions in Taro, Cassava, Sweet potato, yam and Elephant foot Yam.

DOWNLOAD EBOOK →Driven by the fast spread of private irrigation pumps, there has been a rapid expansion of intensive vegetable cultivation in the central Rift Valley in Ethiopia, making it the most important commercial vegetable production cluster in the country. Supporting that “quiet revolution” has been an inflow of migrant laborers – paid through daily, monthly, or piecemeal contracts, with few employment benefits attached to them – and a gig economy as widely-used contractors organize, among others, mechanized land preparation, the digging of wells and ponds, seedling propagation, and loading of trucks. Almost 60 percent of the irrigated area is cultivated by medium-scale tenant farmers relying on short-term rental contracts. It seems that gig economies characterized by flexible contract arrangements implemented by outside contractors, which are increasingly fueling sophisticated sectors in developed countries, are important in these commercial agrarian settings in Africa as well. We further find that the COVID-19 pandemic has led to significant disruptions of this model, as seen by more limited access to services and the unavailability or high price increases in factor markets, especially for labor. We further note large but heterogenous price changes in output markets. The pandemic seems especially to have had important effects on the medium-scale tenant farmers as they depend relatively more than smallholders on outside inputs, labor markets, and these gig economies. However, on the other hand, they benefit more than smallholders from favorable output markets for vegetables.

DOWNLOAD EBOOK →Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation covers about 5 and 9% of the total cultivated land area, respectively.

DOWNLOAD EBOOK →Households with poor health are less likely to adopt productivity-enhancing as well as resource-conserving technologies, which are crucial for achieving the ultimate goal of sustainable agricultural development. The ensuing sickness has also led to reduction in labor allocation to off-farm activities. The findings underline the importance of weighing beforehand the magnitude of potential economic benefits against health costs of water development programs. The overall evidence, however, suggests that carefully designed irrigation dams could significantly improve agricultural production and food security, particularly in areas where waterborne diseases pose negligible risk to health or can be cost-effectively controlled"--Abstract.

DOWNLOAD EBOOK →The world has made enormous progress in the past 50 years toward eliminating hunger and malnutrition. While, in 1960, roughly 30 percent of the world's population suffered from hunger and malnutrition, today less than 20 percent doessome five billion people now have enough food to live healthy, productive lives. Agricultural development has contributed significantly to these gains by increasing food supplies, reducing food prices, and creating new income and employment opportunities for some of the world's poorest people.This book examines where, why, and how past interventions in agricultural development have succeeded. It carefully reviews the policies, programs, and investments in agricultural development that have reduced hunger and poverty across Africa, Asia, and Latin America over the past half century. The 19 successes included here are described in in-depth case studies that synthesize the evidence on the intervention's impact on agricultural productivity and food security, evaluate the rigor with which the evidence was collected, and assess the tradeoffs inherent in each success. Together, these chapters provide evidence of "what works" in agricultural development.
