Following on from the CGIAR study by Evenson and Gollin (published by CABI in 2003), this volume provides up-to-date estimates of adoption outcomes and productivity impacts of crop variety improvement research in sub-Saharan Africa. The book reports on the results of the DIIVA Project that focussed on the varietal generation, adoption and impact for 20 food crops in 30 countries. It also compares adoption outcomes in sub-Saharan Africa to those in South Asia, and guides future efforts for global agricultural research
Bioethanol Production from Food Crops: Sustainable Sources, Interventions and Challenges comprehensively covers the global scenario of ethanol production from both food and non-food crops and other sources. The book guides readers through the balancing of the debate on food vs. fuel, giving important insights into resource management and the environmental and economic impact of this balance between demands. Sections cover Global Bioethanol from Food Crops and Forest Resource, Bioethanol from Bagasse and Lignocellulosic wastes, Bioethanol from algae, and Economics and Challenges, presenting a multidisciplinary approach to this complex topic. As biofuels continue to grow as a vital alternative energy source, it is imperative that the proper balance is reached between resource protection and human survival. This book provides important insights into achieving that balance. - Presents technological interventions in ethanol production, from plant biomass, to food crops - Addresses food security issues arising from bioethanol production - Identifies development bottlenecks and areas where collaborative efforts can help develop more cost-effective technology
This publication presents the latest research in perennial crop breeding and programmes, and provides direction on where the field of perennial crop is heading. Many production systems and agricultural practices are no longer sustainable today as their effects on soils, water, biodiversity, and livelihood are significant. Mainstreaming the use of perennial crops into current practices can contribute to stabilize fragile soils and maintain natural processes essential to obtain stable and high yields. To face the challenges and risks of the twenty-first century, increasing the perenniality of crops and agricultural systems should become a larger research, development and policy focus.
"This beautifully illustrated book reviews scientific and technological information about the world's major food plants and their culinary uses. An introductory chapter discusses nutritional and other fundamental scientific aspects of plant foods. The 100 main chapters deal with a particular species or group of species. All categories of food plants are covered, including cereals, oilseeds, fruits, nuts, vegetables, legumes, herbs, spices, beverage plants and sources of industrial food extracts. Information is provided on scientific and common names, appearance, history, economic and social importance, food uses (including practical information on storage and preparation), as well as notable...
In tropical developing countries farmers tend to grow a wide range of crops in a small area for subsistence or sale. To make full use of often limited resources, a good understanding of how environmental conditions affect the characteristics and performance of these crops is essential. This book considers the response of tropical food crops to environmental factors such as climate, soil and farming system. Three types of crop are considered: cereals, legumes and non-cereal energy crops, with individual chapters on the four most important crops in each group. This material is set in context by introductory chapters on tropical farming systems, tropical climates and tropical soils. This new, updated edition retains the successful formula of the first edition while placing additional emphasis on tropical environmental conservation. It will serve the needs of advanced students of tropical agriculture, as well as professionals engaged in research and extension work in tropical crop production.
Plants and plant-derived products make up the bulk of what we eat and drink every day.... This scientifically accurate photographic guide provides quick and colourful answers. Food Plants of the World is a comprehensive overview of the plants that provide us with food, beverages, spices and flavours. It is written in easy language but gives accurate scientific information on the plants and their uses. Cover, page [4]
This book focuses on the preharvest practices on the production and quality of food crops. Nine chapters are included in this book, which are: Effect of Preharvest Factors on the Quality of Vegetables Produced in the Tropics - Vegetables: Growing Environment and the Quality of Produce; Effects of Agronomic Practices and Processing Conditions on Tomato Ingredients; Modelling Fruit Quality: Ecophysiological, Agronomical and Ecological Perspectives; Sprays Technology in Perennial Tree Crops; Chestnut, an Ancient Crop With Future; Improvement of Grain Legume Production in Semi-Arid Kenya Through Biological Nitrogen Fixation: The Experience With Tepary Bean (Phaseolus Acutifolius a Gray var. Latifolius); Impact of Ozone on Crops; Saffron Quality: Effect of Agricultural Practices, Processing and Storage; Fruit and vegetables Harvesting Systems. It will stimulate readers thinking on key constraints in agriculture and horticulture. Readers will get acquainted with a wide range of information, technologies and methodologies.
