Available in PDF, EPUB and Kindle. Book excerpt: This book discusses policy strategies for the effective management of natural resources in Africa within the context of the United Nations’ Sustainable Development Goals (SDG). While natural resource wealth has the potential to lift many out of poverty, sustain economic growth, and foster political stability, it does not guarantee these benefits. The absolute levels of human development in many resource-rich countries remain low, despite their apparent wealth. The challenge is to adopt policies that better harness the potential of natural resources, not only as an opportunity for development, but also to foster policies and institutional innovations that manage resource wealth equitably and boost human capital. To this end, this volume highlights key opportunities and solutions for harnessing natural resources for sustained economic development and explain how such approaches should be incorporated into the SDG agenda. These opportunities are communicated in the form of policy recommendations that in some cases, are country specific but can (and should) be adapted by individual African countries where applicable. With a broad perspective supplied by a diverse group of authors, this book will be useful for graduate students and academicians studying Africa, development economics, economic policy, and resource management, as well as policy makers, NGOs, and IGOs.

Download or read book Challenging the boxes written by Valerie Dewaelheyns and published by Gompel&Svacina. This book was released on 2018-01-01 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Challenges of sustainability and transition need innovative tools for the understanding, mapping, designing and governing of manmade sites and territories. Complementary to standard land use categories, such as housing and agriculture, this book of essays introduces eleven ‘interface categories’, labels for land use interactions, transitions, mixes, and spatial and temporal positions in between. Authors from different disciplines describe and illustrate how this set of interfaces resonates with their own projects, challenges and agendas, and how it sheds light on new land use agents, on unregistered forms of land occupation, and on opportunities for socio-economic and ecosystem services. The concept of interfaces encourages the development of adapted modes of planning and management for urban, rural or natural environments, and on different spatial scales.

Download or read book Fighting Poverty in Sub Saharan Africa The Multiple Roles of Legumes in Integrated Soil Fertility Management written by Andre Bationo and published by Springer Science & Business Media. This book was released on 2011-08-24 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legumes play an important role in the cropping systems of sub Saharan Africa (SSA). Legumes are an important source of nutrition to both humans and livestock by providing the much needed protein, minerals, fibre and vitamins. The sale of legumes seed, leaves and fibre generates income for the marginalized communities especially women. Cultivation of legumes is essential for the regeneration of nutrient-deficient soils. By biologically fixing nitrogen (BNF) in the soil, legumes provide a relatively low-cost method of replacing otherwise expensive inorganic nitrogen in the soil. This enhances soil fertility and boosts subsequent cereal crop yields. Production of legumes in SSA is however; hampered by a number of constraints among them low and declining soil fertility, low soil pH, high salinity, drought and flooding, poor access to improved germplasm, diseases, pests and weeds. Farmers need to learn how to overcome these constraints if the full benefits of legumes are to be gained. This book presents a synthesis of research work on legumes and draws attention to the importance of legumes in integrated soil fertility management (ISFM) and poverty alleviation in SSA.

Download or read book International Environmental Law and Policy in Africa written by B. Chaytor and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: C.O.OKIDl1 I welcome the opportunity to prepare a Foreword to the book on Environmental Policy and Law in Africa, edited by Kevin R. Gray and Beatrice Chaytor. It is a pleasure to do that because the book is a contribution to the cause of capacity building for development and implementation of environmental law in Africa, a goal towards which I have had an undivided focus over the last two decades. There is still some belief in and outside Africa that for developing countries in general, and Africa in particular, development and implementation of environmental law is not a priority. This belief prevails strongly in many quarters of the industrialised countries. In fact, the view is held either out of blatant ignorance or by some renegade industrialists who fail to appreciate Michael Royston's 1979 thesis that Pollution Prevention Pays.2 That group, for obvious reasons, must have their correspondent counterparts in Africa to provide hope that industries rejected as derelict in the West or inoperable due to rigorous environmental regulation, can find homes to which they can escape and dump their polluting industries.
Download or read book Agroforestry for Soil Management written by Anthony Young and published by Cabi. This book was released on 1997 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry refers to land use systems in which trees or shrubs are grown in association with agricultural crops, or pastures and livestock. From its inception, it has contained a strong element of soil management. Well-designed and managed agroforestry systems have the potential to control run-off and erosion, maintain soil organic matter and physical properties, and promote nutrient cycling. By these means, agroforestry can make a major contribution to sustainable land use. The previous edition of this book, entitled Agroforestry for Soil Conservation (1989), was based on indirect evidence from agriculture, forestry and soil science. The present work provides a new synthesis, drawing on over 700 published sources dating largely from the 1990s. These include both results of field trials of agronomy systems, and research into the plant-soil processes which take place within them. Soil conservation in its narrower sense, the control of erosion, is treated alongside other equally important aspects of soil management, such as nutrient cycling. The new edition summarizes the present state of knowledge and indicates needs for research. It is essential reading for all concerned with agroforestry, whether as students, research scientists, or for practical purposes of development. It is also of interest to soil scientists, agronomists and foresters. Anthony Young was for nine years a Principal Scientist with the International Centre for Research in Agroforestry (ICRAF), Nairobi, Kenya. He was previously Professor of Environmental Sciences at the University of East Anglia, Norwich, UK, from which he received the degree of Doctor of Science. He was a joint author of the FAO standard texts on land evaluation and land use planning. Besides these, his other books include Soil Survey and Land Evaluation (1981) and Land Resources: Now and for the Future (1998). He is now Honorary Research Fellow in Environmental Sciences at the University of East Anglia.

Download or read book Challenging Nature written by Philip W. Porter and published by University of Chicago Press. This book was released on 2006-03 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tanga Region, Tanzania, is an area of persistent rural poverty with a long history of drought, floods, food shortages, famine, and social and economic disruption. Though farmers have been cultivating the land there for hundreds of years, they have consistently been unable to supply adequate food for the region's inhabitants. In Challenging Nature, Philip Porter examines eighteen farming communities to understand what the farmers there know about their environment and which historical and economic factors play into the lack of food security. Porter first began work on this project in 1972, asking 250 farmers in the region about life history, environmental and agricultural changes, types of crops grown and methods of planting, environmental assessments, agricultural practices, food and water supplies, training and education, and attitudes toward nature. Twenty years later, he returned and reinterviewed as many farmers as could be found from the first survey. The result contextualizes the environmental history of the region while informing current and future agricultural development.

Available in PDF, EPUB and Kindle. Book excerpt: This book, Pure and Applied Biogeography, gives a very interesting report and overview about the frontiers of such parts of recent biogeographical research, which plays important roles in solving our most pressing global problems (biodiversity crisis, climate change, water issues, and sustainable agriculture). Our book consists of three sections: "Introduction", "Pure Biogeography and Global Patterns" and "Applied Biogeography and Regional Issues." After the introductory chapter, which is about the main branches and aims of biogeography in service of solving global problems, - we can find three chapters as parts of the first section. First chapter in this section is in close relation with the origin of biodiversity and conservation. The second and third chapters are about the biogeograhical aspects of climate change and biodiversity. In the second section of this book three applied biogeographical chapters can be found, which are related to agriculture, theoretical background of biological plant protection against herbivores, and regional patterns in ecological biogeography.
