This book was released on 2018-09-06 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture continues to play an important role in African economies. According to the African Development Bank, agricultural activities comprise around 15 percent of the continent’s gross domestic product (GDP) and agricultural employment represents around 58 percent of total employment in Sub-Saharan Africa. The region’s population is expected to double to 2 billion people by 2050. Along with expected income growth, the population increase will lead to a substantial rise in food requirements. To meet food demand, FAO estimates that agricultural production would have to increase 112 percent between 2013 and 2050. Meeting this demand will not be easy, as agricultural productivity in SSA remains low and shows slow growth. The vast majority of African smallholder farmers produce low-yield food crops using a minimal set of inputs. Inadequate access to improved inputs such as fertilizers presents a major constraint for smallholders. In the region, more nutrients are removed with harvested crops than are applied with fertilizer or manure, resulting in unsustainable soil nutrient depletion. Improved fertilizer use will help to counteract this trend while substantially improving food security.

Book Synopsis Ecological and Economic Constraints to Crop Production in Sub-Saharan Africa by : Camila Maria Bonilla Cedrez

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a need for a better understanding of options for increasing food production in sub-Saharan Africa (SSA). There are several factors contributing to low crop yields, but low soil fertility stands out and the increased use of inorganic fertilizers could strongly increase it. Despite its centrality in strategic planning and investments, fertilizer usage in SSA remains stubbornly low. Several reasons have been proposed to explain this, including a low response of crops to fertilizer due to poor and overexploited soils; a lack of knowledge by farmers; insufficient availability of credit; high production risk and the need for insurance programs; and low profitability of fertilizer use. These reasons are not mutually exclusive, and it may be that all of them are relevant, in some locations, and for some households. Thus, we need to better understand what the dominant factors (i.e. ecological and economic opportunities) are in different parts of the region, as they may have very different implications for the design of policy and for clarifying additional research gaps. An approach to understanding ecological opportunities is "yield-gap analysis", that compares theoretically attainable yield with actual crop yield. However, current yield gap assessments are generally too simplistic to be helpful. This is because the methods used to calculate it are generally weak (Chapter 1) and because they ignore economic constraints, i.e. input prices (Chapter 2) and output prices (Chapter 3). In order to understand the distribution of opportunities and constraints for a sustainable agricultural intensification, we need to evaluate location-specific ecological and economic conditions and how they translate into crop responses and economic returns to fertilizer investments by smallholder farmers (Chapter 4). This thesis presents a framework for an integrated assessment of fertilizer use profitability by bringing together high spatial and temporal resolution data on soils, weather, and local prices of fertilizer and maize grain. We show, on average, the highest profitability of fertilizer use in maize fields in SSA is between 88 and 345 USD ha−1, depending on the response model used. This would require between 71 and 93 kg ha−1 of fertilizer; and would double maize production in the continent. The average economic yield gap was 1853 kg ha−1, about one fourth of the often-used ecological yield gap benchmark, for which 886 kg ha−1 of fertilizer would be needed. While ecological yield gaps are an important and relevant metric, economic yield gaps are of more relevance for understanding opportunities for agricultural development. Our results highlight the need for agro-ecological approaches to improve soil fertility, policy to support a more efficient fertilizer supply network, and interventions that reduce economical risk such as crop insurance. Our finding that fertilizer is less profitable than suggested by work on the ecological yield gap highlights the importance of an ecological and economic integration. We not only indicate the importance of strategic targeting of fertilizer promotion policies, but also provide a way of doing so with currently available data and analytical approaches. Finally, our results are more relevant to evaluate opportunities for increase crop yield in SSA than ecological yield gap approaches.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1999, this volume is intended to encourage appreciation of the cardinal significance for integrating macroeconomic policy variables and environmental factors and any other relevant externalities into sectoral policy analysis as a tool for improving choice of strategic factors in agricultural development, investment of allocative efficiency in agriculture and environmental protection and overall agricultural development management. The main concern of Matthew Okai is for choosing realistic policy instruments to promote development, quantifying constraints and evaluating the impacts of policy on objectives.

This book was released on 2020-09-19 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Sub-Saharan Africa, the rapidly evolving COVID-19, increasing population growth, and exponential expansion in demand for agricultural commodities are putting pressure on available resources, thereby posing immense challenges to the region’s capacity to achieve nutritional security related to United Nations Sustainable Development Goals (SDGs). Although Sub-Saharan Africa boasts vast, fertile and uncultivated arable lands, its capacity to contribute to feeding its current and future population is being seriously undermined by factors such as poor adoption and utilization of innovations and digital tools, climate change impact, environmental degradation, weak political will, limited interest in farming, lack of government support, and more. In spite of these constraints, sustainable agriculture, food security and nutrition security in Sub-Saharan Africa can be achieved by adopting a multi-pronged approach, which includes improved agricultural mechanization, adoption of high yielding crop varieties, use of information technology, public investments in improved technologies, and rural infrastructure funding. This edited volume provides innovative policy tools for enhancing Sub-Saharan Africa's capacity to achieve sustainable agriculture, food security and nutrition security in the digital age and in the face of climate variability. Furthermore, this book presents smart strategies for increased agricultural production, reduced food waste, and enhanced nutritional outcomes by harnessing the latest discoveries in agricultural research, education and advisory services.

This book was released on 1991-09-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.

This book was released on 2012-02-12 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security, one of the basic human rights, seems to be ever eluding the people of sub-Saharan Africa. With each occurrence of crop failure, agriculturalists around the world reawaken to the challenge of ensuring sta ble, adequate food production in the tropical African environments. The International Fertilizer Development Center (IFDC), with its mandate of alleviating food shortages through judicial use of fertilizers, formulated a program to study fertilizer use strategies for sub-Saharan Africa. With gener ous financial assistance from the International Fund for Agricultural Devel opment (IFAD), IFDC, in collaboration with the International Crop Re search Institute for the Semi-Arid Tropics (ICRISAT) and the International Institute for Tropical Agriculture (IIT A), initiated a research project aimed at assessing means to remedy soil nutrient deficiencies that constrain food production in the humid, subhumid, and semiarid tropics of Africa. The results of this project were summarized during a workshop held in Togo, March 25-28, 1985; the proceedings of that meetings are found in this vol ume. The project established collaboration with numerous national programs that were responsible for much of the data collection. The data presented in Chapters 6 and 9 include much of this information.
