Download or read book Sustainable Intensification in Smallholder Agriculture written by Ingrid Oborn and published by Taylor & Francis. This book was released on 2017-02-17 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems and institutional innovation. Much of the work represents outputs of the three CGIAR Research Programs on Integrated Systems for the Humid Tropics, Aquatic Agricultural Systems and Dryland Systems. The chapters are based around four themes: the conceptual underpinnings of systems research; sustainable intensification in practice; integrating nutrition, gender and equity in research for improved livelihoods; and systems and institutional innovation. While most of the case studies are from countries and agro-ecological zones in Africa, there are also some from Latin America, Southeast Asia and the Pacific.

Download or read book Transforming Tertiary Agricultural Education in Africa written by David Kraybill and published by CABI. This book was released on 2021-11-24 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enormous changes are affecting African production agriculture, urbanization, and food consumption patterns, requiring new approaches to training and knowledge generation and dissemination to achieve food security. Many agricultural universities and other tertiary agricultural education (TAE) organizations have been slow to respond, hindered by inadequate staffing and facilities and growing competition for funds. However, some African agricultural universities are transforming themselves and are achieving remarkable success. This book documents successful approaches to remaking TAE in Africa to inspire leaders, both formal and informal, of other TAE organizations. It emphasises adaptive strategies and processes creating an internal culture driven by stakeholder needs and where organizational transformation improves the quality and relevance of teaching, research, and outreach. The chapters cover the role of TAE in agricultural transformation, trends in TAE in Africa, solutions to the rigour-versus-relevance dilemma, curriculum design informed by actual and emerging labour market conditions, innovation and entrepreneurship, TAE quality assurance, and networking among TAE institutions.

Download or read book Soil Phosphorus written by Rattan Lal and published by CRC Press. This book was released on 2016-09-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

Download or read book The End of Desertification written by Roy H. Behnke and published by Springer. This book was released on 2016-04-12 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.
