West and Central African nations face major obstacles to achieving the Millennium Development Goal of cutting poverty and hunger in half by 2015, not least among them the fragile state of their agriculture. Although most regional economies depend on agriculture for employment, national income, and export revenues, farm productivity tends to be low, owing to relatively little use of chemical fertilizers, improved seeds, and other modern technologies. Yield Gaps and Potential Agricultural Growth in West and Central Africa responds to this problem by identifying potential areas of growth in the agricultural and livestock sectors. Using data on the soil, water availability, and weather in different parts of West and Central Africa, the authors find significant gaps in different locations between the potential and actual yield of various agricultural products. They then use an economywide multimarket model to simulate the future economic effects of closing these yield gaps. In coastal nations, crops such as cassava, cereals, and yams have the greatest yield gaps, whereas, in the Sahel, livestock, rice, coarse grains and oilseeds (groundnuts) have more room for growth. Although identifying these yield gaps does not guarantee that they can be closed, it does provide a focus for development efforts in the region. The authors conclude, moreover, that if such efforts involve transnational cooperation in agricultural research, marketing, and other areas, they could produce significant benefits across West and Central Africa. This study's findings will be of interest to policymakers, researchers, and others concerned with African development.

To feed a world population that will exceed 9 billion by 2050 requires an estimated 60% increase over current primary agricultural productivity. Closing the common and often large gap between actual and attainable crop yield is critical to achieve this goal. To close yield gaps in both small and large scale cropping systems worldwide we need (1) definitions and techniques to measure and model yield at different levels (actual, attainable, potential) and different scales in space (field, farm, region, global) and time (short and long term); (2) identification of the causes of gaps between yield levels; (3) management options to reduce the gaps where feasible and (4) policies to favour adoption of sustainable gap-closing solutions. The aim of this publication is to critically review the methods for yield gap analysis, hence addressing primarily the first of these four requirements, reporting a wide-ranging and well-referenced analysis of literature on current methods to assess productivity of crops and cropping systems.

This book offers an in-depth analyses of value chain policies, past and present in West Africa. The book contains a large number of in-depth case studies of food value chains in particular countries, including traditional export commodities (cocoa, cotton), high value exports (mangoes, horticulture) and the most important staple food value chains (oil palm, rice, maize, sorghum and millet and cassava) in the region. It also contains a large number of private and public initiatives, and thematic analyses relating to the role of the private agro-industry and producer organizations and their role as market agents.

What are the challenges and action points for agricultural sustainability in Sub-Saharan Africa? This open access collection of papers offers technical analyses, policy recommendations and an overview of success stories to date. Each carefully selected paper provides valuable insights for improved policy making and defines relevant strategic priorities on Africa’s sustainable transformation process, which is in line with the international development agenda. Although agriculture remains the main source of income for Africa’s population, the sector is rain-fed subjecting it to the vagaries of weather and climate change. This volume demonstrates the rationale of developing a competitive, inclusive and sustainable agribusiness sector for Africa’s food security and structural transformation. From the impact of Bioenergy crop adoption and Drought Index Insurance to Agro-Industrialization, this volume is important reading for individual researchers, academic associations and professional bodies interested in African agricultural development.

Cover Crops in West Africa Contributing to Sustainable Agriculture

This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.

This book features a comprehensive foresight assessment, exploring the pressures — threats as well as opportunities — on the global agriculture & food systems between now and 2050. The overarching aim is to help readers understand the context, by analyzing global trends and anticipating change for better planning and constructing pathways from the present to the future by focusing on the right questions and problems. The book contextualizes the role of international agricultural research in addressing the complex challenges posed by UN 2030 Agenda and beyond, and identifies the decisions that scientific leaders, donors and policy makers need to take today, and in the years ahead, to ensure that a global population rising to nine billion or more combined with rising incomes and changing diets can be fed sustainably and equitably, in the face of the growing climate threats.
