Fruits & vegetable value chains (F&V VC) in Nigeria hold significant potential to continue toward sustainable, inclusive food system transformation. Domestic food system growth, including that of F&V, remains crucial in achieving a healthy food environment and serving as a source of various micronutrients. There is a need for bundles of innovations to address multiple challenges along F&V VC in Nigeria, characterized by a set of challenges that are unique to developing countries and F&V. V&F VC consists of many small actors, farmers, and traders, whereby limited vertical coordination can lead to significant efficiency loss along the value chain. Seasonal and temporal variations in supply-dem...
This book focuses on food security and safety issues in Africa, a continent presently challenged with malnutrition and food insecurity. The continuous increase in the human population of Africa will lead to higher food demands, and climate change has already affected food production in most parts of Africa, resulting in drought, reduced crop yields, and loss of livestock and income. For Africa to be food-secure, safe and nutritious food has to be available, well-distributed, and sufficient to meet people’s food requirements. Contributors to Food Security and Safety: African Perspectives offer solutions to the lack of adequate safe and nutritious food in sub-Saharan Africa, as well as highl...
Neglected and Underutilized Crops: Future Smart Food explores future food crops with climate resilience potential. Sections cover their botany, nutritional significance, global distribution, production technology, and tolerance to biotic and abiotic stresses of neglected and underutilized crops. By simply changing species in a crop rotation system, the cycle of some pests and diseases is disrupted and probabilities of infestations are reduced. Finally, the book provides case studies that highlight where the adaptation of crops to local environments, especially with regard to climate change, have been successful.These crops can help make agricultural production systems more resilient to clima...
This handbook covers a whole range of issues relating to local seed supply systems, including participatory plant breeding, and both technical and practical information on seed production and variety maintenance. It suggests new approaches and methods to support on-farm seed production by small-scale farmers in developing countries. The first part of the book describes the functioning of local seed systems and discusses their strengths, limitations and possibilities for improvement. The authors discuss in detail issues of genetic diversity and in-situ conservation, farmers' rights and legislation. The cases presented here illustrate the functioning of local seed systems and experiences with ...
Research data is expensive and precious, yet it is seldom fully utilized due to our ability of comprehension. Graphical display is desirable, if not absolutely necessary, for fully understanding large data sets with complex interconnectedness and interactions. The newly developed GGE biplot methodology is a superior approach to the graphical analys
La vallée du fleuve Niger, au Bénin, a connu ces dernières années des inondations aux conséquences économiques et sociales véritablement catastrophiques. Ces inondations frappent des couches sociales très pauvres et aggravent ainsi leur vulnérabilité. Ce mémoire de thèse vise à améliorer la compréhension des facteurs responsables des inondations, afin de mener des réflexions qui permettront de trouver une solution définitive à cette catastrophe qui devient récurrente. Pour mener cette étude, une cartographie du secteur d’étude a été effectuée sur la base d’un système d’information géographique avec les indicateurs de vie. Ainsi, la carte du risque d’inondati...
While tomatoes continue to be one of the most widely grown plants, the production and distribution of tomato fruits have been changing worldwide. Smaller, flavorful tomatoes are becoming more popular than beefsteak tomatoes, greenhouse-grown tomatoes have entered the marketplace, and home gardeners are using the Internet to obtain information for g
