Book Description
This book looks at significant current grassland problems and issues, and provides an insight into grassland productivity in diverse areas of the world, with their various production systems. There is a focus on recent technical advances and the prospects for further innovation, through twenty-one chapters by eminent grassland scientists, grouped into seven sections - forage germplasm; forage conservation; grass-based systems and organic production; climate change, biodiversity and biotechnology; geographical information systems; farmer and pastoralist participation; and regional developments. The book is timely in view of the expanding human and livestock populations, especially in arid and semi-arid environments, with the consequent pressure on the world's grasslands.

Book Description
Forest degradation as a result of logging, shifting cultivation, agriculture and urban development is a major issue throughout the tropics. It leads to loss in soil fertility, water resources and biodiversity, as well as contributes to climate change. Efforts are therefore required to try to minimize further degradation and restore tropical forests in a sustainable way. This is the first research-based book to examine this problem in East Africa. The specific focus is on the forests of Ethiopia, Tanzania and Uganda, but the lessons learned are shown to be applicable to neighbouring countries and others in the tropics. A wide range of forest types are covered, from dry Miombo forest and afromontane forests, to forest-savannah mosaics and wet forest types. Current management practices are assessed and examples of good practice presented. The role of local people is also emphasized. The authors describe improved management and restoration through silviculture, plantation forestry and agroforestry, leading to improvements in timber production, biodiversity conservation and the livelihoods of local people.

Book Description
The World Summit on Sustainable Development (WSSD) in Johannesburg 2002 was the latest conference in an international process to manage environment and development issues that can be traced back to the late 1960s. Three milestones mark this 30-year process of social and political interaction: the United Nations Conference on the Human Environment (UNCHE), held in Stockholm in 1972, the first international meeting at a high political level convened to address environmental issues; the 1992 United Nations Conference on Environment and Development (UNCED), held in Rio de Janeiro; and the WSSD, which attempted to set policy goals and targets for the global environmental and developmental challenges previously identified.But what did the WSSD achieve? Following the summit there have been various opinions of its significance and its outputs, many of them negative. This book argues that there is a need to place the WSSD in its broader context. Understanding the connections between the WSSD and its precedents as well as those between this overall process and individual environmental decision-making processes (such as on climate change), and how they all contribute to the overall global policy process, adds a critical dimension to the analysis of the WSSD outcomes. This book examines the challenges facing the global policy process for sustainable development as it continues beyond Johannesburg into the future. It combines a forward outlook with a historical perspective in tracing the evolution of selected cross-cutting themes on the agenda of the three conferences, the institutions and formal results of the process, and the actors and their patterns of interaction over time. The focus is on the decision-making dimension – the multilateral negotiations-which can be seen as the development over time of a pattern of interlinked political activities.Global Challenges has four operational objectives: first, to define the ongoing process that formally began with the Stockholm Conference in 1972 and evolved towards its latest major manifestation at the WSSD; second, to present some dynamics of the Stockholm–Rio–Johannesburg (SRJ) process by exploring the themes identified; third, to introduce an approach on how to consider the outcomes of this process as a way of reflecting on what the process has actually accomplished; and, finally, to discuss lessons learned for theory and practice from this exercise. The practical lessons include reflections on how the continued SRJ process should best be organised and supported into the future. The book takes a uniquely broad outlook and interdisciplinary approach in addressing important lessons relating to the emergence of substantive issues as well as to process and institutional dynamics. It is a bridge-building exercise from academic analysis to long-term strategic thinking in environmental regime building. Global Challenges provides a new perspective on the continuing and increasingly complex global environment and development policy process and analyses the interlinkages between the process, trends and cross-cutting issues that set the conditions for the global efforts to achieve sustainable development. It will be essential reading for academics and practitioners interested in seeing the big picture of the global challenges facing people and planet in the 21st century.

Book Description
In this newly revised and expanded edition of the award-winning International Environmental Policy, Lynton Keith Caldwell updates his comprehensive survey of the global international movement for protection of the environment. Serving as a history of international cooperation on environmental issues, this book focuses primarily on the development of international agreements and institutional arrangements--both governmental and nongovernmental--along with the impact of science, technology, trade, and communication on environmental policy. With implications for multinational commerce, population policy, agriculture, energy issues, biological and cultural diversity, transnational equity, ideology, and education, this book takes a broad view of the policy outcomes of what may be the most important social movement of the 20th century, and addresses the events and politics that have significantly affected the movement over the last twenty years and will continue to affect it into the next century.
