At a time when Africa's food security stands threatened, Realizing Africa's Rice Promise provides a comprehensive overview of state-of-the-art research and recommendations for dealing with future challenges. With contributions from the key scientists working on rice in Africa, this volume addresses policy, genetic diversity and improvement, sustainable productivity enhancement, innovations and value chains. The book is useful for researchers, policy makers, agricultural ministries, donors, regional and sub-regional organizations, non-governmental development organizations and universities.
The book is designed to provide a review on the methods and current status of conservation of the tropical plant species. It will also provide the information on the richness of the tropical plant diversity, the need to conserve, and the potential utilization of the genetic resources. Future perspectives of conservation of tropical species will be discussed. Besides being useful to researchers and graduate students in the field, we hope to create a reference for a much wider audience who are interested in conservation of tropical plant diversity.
'Biopiracy' refers either to the unauthorised extraction of biological resources, such as plants with medicinal properties, and associated traditional knowledge from indigenous peoples and local communities, or to the patenting of spurious 'inventions' based on such knowledge or resources without compensation. Biopiracy cases continue to emerge in the media and public eye, yet they remain the source of considerable disagreement, confusion, controversy and grief. The aim of this book is to provide the most detailed, coherent analysis of the issue of biopiracy to date.The book synthesises the rise of the issue and increasing use of the term by activists and negotiators in the World Trade Organization (WTO) and the Convention on Biological Diversity (CBD), to form a critical understanding of the themes, implications and politics of biopiracy. Taking a case-study based approach, derived from interviews and fieldwork with researchers, government, industry, local farmers, healers and indigenous people, the author sequentially documents events that have occurred in biopiracy and bioprospecting controversies. Implications and ethical dilemmas are explored, particularly relating to work with local communities, and the power relations entailed. Detailing international debates from the WTO, CBD and other fora in an accessible manner, the book provides a unique overview of current institutional limitations and suggests ways forward. Options and solutions are suggested which are relevant for local communities, national governments, international negotiators, NGO and interest groups, researchers and industry.
This book presents a wealth of both general and specific information about rice. The first section outlines the distribution and mutual relationships of various types of rice with special attention to the adaptive strategy of wild and cultivated rice, and to the relationships between different ecotypes and their adaptation to low temperature, different photoperiods or different humidities. The section on rice morpho-physiology compares the characteristics of rice and dry land crops and different ecotypes with regard to seed dormancy and germination; describes the important steps in the photosynthetic structure process and its adjustment to the course of evolution of cultivated rice; studies the root and nutrient uptake and the responses to hormones in terrestrial and aquatic plants; considers the reproductive nature in relation to tolerance to environmental stress; and discusses the morphological characteristics of rice panicle in relation to grain filling, sink-source balance and variation in yield components of panicle structure. The last section reviews the genetics of rice and includes new findings on chromosomal analysis, cytoplasmic analysis and gene analysis and reviews recent achievements in tissue culture and genetic engineering techniques.The book is authoritative, well-documented and international in scope. It presents new and useful information of direct use to rice research workers and students, and of interest to crop physiologists, agronomists, plant physiologists and breeders throughout the world.

Origin and Phylogeny of Rices provides an evolutionary understanding of the origin, spread, and extent of genetic diversity in rice. This single volume is the first to review and synthesize the significant work done in this area in the last 30 years.Rice is the most important food crop of humankind. It provides more energy and also forms the staple food for more humans than any other food plant. This book assesses multiple aspects of this crucial crop in chapters devoted to rice's history and spread, phylogeny of the genus Oryza, Oryza species and their interrelationships, and the origins of west African and Asian rice. - Offers an interpretive review of the latest research on this vital crop - Guides further research and understanding with an extensive list of references - Enhances the presentation of concepts via illustrations throughout
