Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the delivery of outputs, and their uptake by farming communities in SSA. They evaluate both successes and failures of past investments in soil fertility research and important lessons learnt which provide crucial information for national and international scientists currently engaged in this research area. The book is organised in a number of chapters each covering a chronological period characterised by its primary research content and approaches and by the dominant research paradigms and delivery models.
The Green Revolution – the apparently miraculous increase in cereal crop yields achieved in the 1960s – came under severe criticism in the 1970s because of its demands for optimal irrigation, intensive use of fertilisers and pesticides; its damaging impact on social structures; and its monoculture approach. The early 1980s saw a concerted approach to many of these criticisms under the auspices of Consultative Group on International Agricultural Research (CGIAR). This book, first published in 1987, analyses the recent achievements of the CGIAR and examines the Green Revolution concept in South America, Asia and Africa, from an ‘ecodevelopment’ standpoint, with particular regard to the plight of the rural poor. The work is characterised by a concern for the ecological and social dimensions of agricultural development,which puts the emphasis on culturally compatible, labour absorbing and environmentally sustainable food production which will serve the long term needs of developing countries.

Preharvest Modulation of Postharvest Fruit and Vegetable Quality is the first book to focus on the potential yield quality, quantity and safety benefits of intervention during growth. Of the many factors responsible for overall quality of produce, about 70 percent comes from pre-harvest conditions. Written by an international team of experts, this book presents the key opportunities and challenges of pre-harvest interventions. From selecting the most appropriate growing scenario, to treating plants during the maturation process, to evaluating for quality factors to determine appropriate interventions, this book provides an integrated look at maximizing crop yield through preventative means. In fact, with the very best of postharvest knowledge and technologies available, the best that can be achieved is a reduction in the rate at which products deteriorate as they progress through their normal developmental pattern of maturation, ripening and senescence. Therefore, it is very important to understand what pre-harvest factors influence the many important harvest quality attributes that affect the rate of postharvest deterioration and, subsequently, the consumers' decision to purchase the product in the marketplace. - Presents the important pre-harvest factors that influence harvest quality - Includes up-to-date information on pre-harvest factors that modulate post-harvest biology - Identifies potential methodologies and technologies to enhance pre-harvest interventions
