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.

Africa is a fire continent. Since the early evolution of humanity, fire has been harnessed as a land-use tool. Many ecosystems of Sub-Sahara Africa that have been shaped by fire over millennia provide a high carrying capacity for human populations.

The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.

Long considered both best friend and worst enemy to humankind, fire is at once creative and destructive. On the endangered tropical island of Madagascar, these two faces of fire have fueled a century-long conflict between rural farmers and island leaders. Based on detailed fieldwork in Malagasy villages and a thorough archival investigation, Isle of Fire offers a detailed analysis of why Madagascar has always been aflame, why it always will be aflame, and ultimately, as Christian Kull argues, why it should remain aflame.

Political ecology and science studies have found fertile meeting ground in environmental studies. While the two distinct areas of inquiry approach the environment from different perspectives—one focusing on the politics of resource access and the other on the construction and perception of knowledge—their work is actually more closely aligned now than ever before. Knowing Nature brings together political ecologists and science studies scholars to showcase the key points of encounter between the two fields and how this intellectual mingling creates a lively and more robust ecological framework for the study of environmental politics. The contributors all actively work at the interface between these two fields, and here they use empirical material to explore questions of theoretical and practical import for understanding the politics that surround nature-society relations, from wildlife management in the Yukon to soil fertility in Kenya. In addition, they examine how various environmental knowledge claims are generated, packaged, promoted, and accepted (or rejected) by the different actors involved in specific cases of environmental management, conservation, and development. Finally, they ask what is at stake in the struggles surrounding environmental knowledge, how such struggles shape conceptions of the environment, and whose interests are served in the process.
