The strength of this book is that it is written by someone who has spent a lifetime devoted to the science of economic botany. The author has brought together his vast experience in the field in Africa with his studies of arid land plants at the Royal Botanic Gardens, Kew. The result is an informative and reliable text that covers a vast range of topics. It is also firmly based upon the author's research and interest in plant taxonomy and therefore fully acknowledges the importance of correct naming and classification in the field of science of economic botany. The coverage is of economic botany in its broadest sense. I was delighted to find such topics as ecophysiology, plant breeding, the environment and conservation are included in the text. This gives the book a much more comprehensive coverage than most other texts on the subject. I was also glad to see that the book covers the use of various organisms that are no longer considered part of the plant kingdom such as various species of fungi and algae. It is indeed a broad ranging book that will be of use to many people interested in the uses of plants and fungi. Economic botany is once again being given more prominence as a discipline because of its enormous relevance to both conservation and sustainable development. Those people involved in those topics shOUld find this a most useful resource.

This book aims at both academics and professionals in the field of forest-people interfaces. It takes the reader on a journey through four major themes that have emerged since the initiation of 'social forestry' in the 1970s: non-timber forest products and agroforestry; community-based natural resource management; biocultural diversity; and forest governance. In so doing, the books offers a comprehensive and current review on social issues related to forests that other, more specialized publications, lack. It is also theory-rich, offering both mainstream and critical perspectives, and presents up-to-date empirical materials. Reviewing these four major research themes, the main conclusion of the book is that naïve optimism associated with forest-people interfaces should be tempered. The chapters show that economic development, political empowerment and environmental aims are not easily integrated. Hence local landscapes and communities are not as 'makeable' as is often assumed. Events that take place on other scales might intervene; local communities might not implement policies locally; and governance practices might empower governments more than communities. This all shows that we should go beyond community-based ideas and ideals, and look at practices on the ground.

This document attempts to present the current state of knowledge on agroforestry parkland systems. These systems, which for many local populations are very important for food security, income generation and environmental protection, are found primarily in the semi-arid and sub-humid zones of West Africa. The document first provides a thorough description of their distribution and diversity and discusses different ways of classifying them. It also presents data on current trends in parkland development and assesses determining factors. The document then provides an in-depth analysis of biophysical tree-soil-crop interactions and the factors regulating them, and describes various improved parkland management techniques. It goes on to examine the strength and limitations of institutional arrangements as well as the constraints imposed by Sahelian forest policies on the sustainable management of parklands. The production, use and marketing of parkland products is reviewed with an emphasis on their contribution to food security, local and national income as well as social values. Overall costs and benefits of the practice of parkland agroforestry are evaluated. In conclusion, the document identifies crucial research needs and promising avenues for promoting sustainable management of parkland systems.

One path to solving the food security problem in Africa is to broaden the spectrum of crops cultivated and animals husbanded on the continent to include non-traditional species such as wildlife, and to develop new and innovative production systems to complement the conventional systems. In looking at the role of wildlife in food security in Africa, this publication is concerned not only with the direct contribution of wildlife as a food resource, but also with the influence of wildlife on access to food through employment and income generation, its influence on physical, spiritual and cultural well-being of people. as well as its positive and negative influences on food production capabilities.--Introduction.

The series "Commodities at a Glance" aims to collect, present and disseminate accurate and relevant statistical information linked to international primary commodity markets in a clear, concise and reader-friendly format. This issue of "Commodities at a Glance" explores the economic, social and environmental relevance of the gum arabic sector, with a focus on supply, demand, prices and market organization. Gum arabic is the most commercially valuable exudate gum, with wide applications in industries as diverse as food and beverages, pharmaceuticals, cosmetics, and printing. The gum is produced primarily in arid wooded savannas in sub-Saharan Africa, and consumed predominantly by manufacturers in developed and emerging economies. Due to its potential to generate foreign exchange reserves, ensure food security, promote sustainable agriculture and forestry, and combat desertification and climate change, gum arabic is a promising commodity for a number of African countries. However, in order to overcome the current uneven distribution of economic gains along the gum arabic value chain, producing countries must increase local processing and ensure higher compensation for resource-poor gum collectors.

Soil erosion affects a large part of the Earth surface, and accelerated soil erosion is recognized as one of the main soil threats, compromising soil productive and protective functions. The land management in areas affected by soil erosion is a relevant issue for landscape and ecosystems preservation. In this book we collected a series of papers on erosion, not focusing on agronomic implications, but on a variety of other relevant aspects of the erosion phenomena. The book is divided into three sections: i) various implications of land management in arid and semiarid ecosystems, ii) erosion modeling and experimental studies; iii) other applications (e.g. geoscience, engineering). The book covers a wide range of erosion-related themes from a variety of points of view (assessment, modeling, mitigation, best practices etc.).

Foregrounding African women’s ingenuity and labor, this pioneering case study shows how women in rural Mali have used technology to ensure food security through the colonial period, environmental crises, and postcolonial rule. By advocating for an understanding of rural Malian women as engineers, Laura Ann Twagira rejects the persistent image of African women as subjects without technological knowledge or access and instead reveals a hidden history about gender, development, and improvisation. In so doing, she also significantly expands the scope of African science and technology studies. Using the Office du Niger agricultural project as a case study, Twagira argues that women used modest technologies (such as a mortar and pestle or metal pots) and organized female labor to create, maintain, and reengineer a complex and highly adaptive food production system. While women often incorporated labor-saving technologies into their work routines, they did not view their own physical labor as the problem it is so often framed to be in development narratives. Rather, women’s embodied techniques and knowledge were central to their ability to transform a development project centered on export production into an environmental resource that addressed local taste and consumption needs.

Tree based production systems abound especially in the tropics. Despite the pervasiveness of such multipurpose “trees-outside-forest” resources, they have not attracted adequate attention in the development paradigms of many nation states. These multispecies production systems impact the ecosystem processes favourably. Yet, our understanding of the diversity attributes and carbon dynamics under agroforestry is not adequate. This book focuses on the role of multispecies production systems involving tree and crop species as a means for carbon sequestration and thereby reduce atmospheric carbon dioxide levels. Sixteen chapters organized into three broad sections titled: Measurement and Estimation, Agrobiodiversity and Tree Management, and Policy and Socioeconomic Aspects represent a cross section of the opportunities and challenges in current research and emerging issues in harnessing carbon sequestration potential of agroforestry systems.
