Farming Systems in the Nigerian Savanna by David Norman Pdf
Presenting the case for a farming systems approach to research in developing countries, this book considers the role of new technology and appropriate development strategies in improving agricultural production and the welfare of farming families in the semi-arid tropical region of West Africa.
Farming Systems In The Nigerian Savanna by David Norman Pdf
This book embodies work stretching over a fifteen year period. As a result· inevitably we are greatly indebted to a number of institutions and a large number of individuals. Over the years considerable administrative and financial help was provided by the Institute for Agricultural Research, Ahmadu Bello University, the Ministries of Agriculture and Natural Resources in the northern states of Nigeria, the Ford Foundation, and more recently, Kansas State University.
Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem? Until now, doubts have been expressed as to the actual capacity of the soils to sustain a desirable increase of production which can match the requirements of a fast-growing population. Thirty years of investigation and a renewed comprehensive interpretation of research data on soil fertility show that a sustainable agriculture growth could be a practical possibility in a savannah region.

Indigenous Agricultural Revolution by Paul Richards Pdf
Originally published in 1985, this book argues forcefully and practically for new relationship between science and the small farmer. It advocates scientific research seeking out changes which are already taking place within the smallholder farming sector and building on local initiatives. Drawing on his experience of West Africa, the author demonstrates that many of the most successful innovations in food-crop production during the 20th century have indigenous roots and that there should therefore be less emphasis on ‘teaching’ farmers how to farm and more emphasis on how to foster and support local adaptation and inventiveness. This book will be of interest to students of agriculture, environmental studies and rural development as well as those working with relief and development agencies.
Farming Systems and Food Security in Africa by John Dixon,Dennis P. Garrity,Jean-Marc Boffa,Timothy O. Williams,Tilahun Amede,Christopher Auricht,Rosemary Lott,George Mburathi Pdf
Knowledge of Africa’s complex farming systems, set in their socio-economic and environmental context, is an essential ingredient to developing effective strategies for improving food and nutrition security. This book systematically and comprehensively describes the characteristics, trends, drivers of change and strategic priorities for each of Africa’s fifteen farming systems and their main subsystems. It shows how a farming systems perspective can be used to identify pathways to household food security and poverty reduction, and how strategic interventions may need to differ from one farming system to another. In the analysis, emphasis is placed on understanding farming systems drivers of change, trends and strategic priorities for science and policy. Illustrated with full-colour maps and photographs throughout, the volume provides a comprehensive and insightful analysis of Africa’s farming systems and pathways for the future to improve food and nutrition security. The book is an essential follow-up to the seminal work Farming Systems and Poverty by Dixon and colleagues for the Food and Agriculture Organization (FAO) of the United Nations and the World Bank, published in 2001.
Savanna Woody Plants and Large Herbivores by Peter Frank Scogings,Mahesh Sankaran Pdf
Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.
Agro-Ecological Intensification of Agricultural Systems in the African Highlands by Bernard Vanlauwe,Piet van Asten,Guy Blomme Pdf
There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
