Maize is an important food crop in Ghana, accounting for more than 50 percent of the countrys total cereal production. The Ghana Grains Development Project (19791997) and the Food Crops Development Project (20002008) made major investments to improve maize yield. Despite these efforts, the average maize yield in Ghana remains one of the lowest in the world, much lower than the average for Africa south of the Sahara.

The bioeconomy concept aims to add sustainability to the production, transformation, and trade of biological goods. Though implemented around the world, the development of national bioeconomies is uneven, especially in the global South, where major challenges exist in Sub-Saharan Africa. In this context, the international BiomassWeb project aimed to underpin the bioeconomy concept by applying the value web approach, which seeks to uncover complex interlinked value webs instead of linear value chains. The project also aimed to develop intervention options to strengthen and optimize the synergies and trade-offs among different value chains. The Special Issue “Advances in Food and Non-Food Biomass Production, Processing and Use in Sub-Saharan Africa: Toward a Basis for a Regional Bioeconomy" compiles 23 articles produced in this framework. The articles are grouped in four sections: the value web approach; the production side; processing, transformation and trade; and global views.

In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

"Smallholder farmers are the stewards of more than 80 percent of the world's farms. These small family businesses produce about one-third of the world's food. In Africa and Asia, smallholders dominate the production of food crops, as well as export commodities such as cocoa, coffee, and cotton. However, smallholders and farm workers remain among the poorest segments of the population, and they are on the frontline of climate change. Smallholder farmers face constraints in accessing inputs, finance, knowledge, technology, labor, and markets. Raising farm-level productivity in a sustainable way is a key development priority. Agribusinesses are increasingly working with smallholder farmers in low- and middle-income countries to secure agricultural commodities. More productive smallholders boost rural incomes and economic growth, as well as reduce poverty. Smallholders also represent a growing underserved market for farm inputs, information, and financial services. Working with Smallholders: A Handbook for Firms Building Sustainable Supply Chains (third edition) shows agribusinesses how to engage more effectively with smallholders and to develop sustainable, resilient, and productive supply chains. The book compiles practical solutions and cutting-edge ideas to overcome the challenges facing smallholders. This third edition is substantially revised from the second edition and incorporates new material on the potential for digital technologies and sustainable farming. This handbook is written principally to outline opportunities for the private sector. The content may also be useful to the staffs of governmental or nongovernmental development programs working with smallholders, as well as to academic and research institutions."--
