This book is about the ‘how’ of desertification control as opposed to an analysis of the ‘why’ and fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands. There are numerous illustrations to show the successful techniques. This compilation demonstrates that desertification and land degradation can be controlled and reversed with existing techniques in such widely varying environments as the Sahel of Africa to Sri Lanka and the Philippines in SE Asia, from mountains in Lesotho to low lands on desert margins in Mongolia. Proven approaches include technical interventions, changes in governance and to the legislative framework and policy reform. The book fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands.
The conference "Combating Desertification with Plants" was held in Beer Sheva, Israel, from November 2-5, 1999, and was attended by 70 participants from 30 countries and/or international organisations. Desertification - the degradation of soils in drylands - is a phenomenon occurring in scores of countries around the globe. The number of people (in semiarid regions) affected by the steady decline in the productivity of their lands is in the hundred millions. The measures required to halt and reverse the process of desertification fall into many categories - policy, institutional, sociological-anthropological, and technical. Although technical "solutions" are not currently in vogue, the conference organizers felt that perhaps the pendulum had swung too far in the direction of "participatory approaches." Hence IPALAC - The International Program for Arid Land Crops - whose function is to serve as a catalyst for optimizing the contribution of plant germplasm to sustainable development in desertification-prone regions - felt the time was opportune for providing a platform for projects where the "plant-driven" approach to development finds expression. Some 45 papers were delivered at the conference, falling into the categories of this volume: Overview, Potential Germplasm for Arid Lands, Introduction, Domestication and Dissemination of Arid Land Plants, Land Rehabilitation, and Mechanisms of Plant Transfer. The conference was funded by UNESCO (Division of Ecological Sciences), the Ministry of Foreign Affairs of Finland, and MASHAV, Israel's Center for International Development Cooperation.
After the devastating dust storms that swept across Northern China in 2000, there has been increased interest in studying experiences with dust storm mitigation, prevention, forecasting and control. This book contains a range of essays and case studies written by a group of Chinese and international experts with experience in the field of dryland rehabilitation and ecological restoration of desertified lands at the global and local level. Issues discussed include: the experiences in Canada and the US during the Dust Bowl era of the 1930's; the desertification of areas on the continents of Australia and Africa; case studies from Asia which look at the consequences of the large-scale implementation of policies and land-use practices; and methods for the forecasting, mitigation and prevention of dust storms.
The book specifies infrastructure construction achievements and the present development situation in China in the 30 years after the reform and opening up in the fields of architecture, energy, transportation, environmental protection, water conservancy, telecommunications, urban arts and sports. The book also summarizes the experiences and lessons in the course of the construction and puts forward the development requirements and prospects in the hope of providing reference and enlightenment for African people in their infrastructure construction and offering certain help for their smooth construction work in order to avoid disadvantages and achieve better economic and social benefits.
Social science from Western countries continues to have the greatest global influence, but the field is expanding rapidly in Asia and Latin America, particularly in China and Brazil. In sub-Saharan Africa, social scientists from South Africa, Nigeria andKenya produce 75% of academic publications. In South Asia, barring some centres of excellence in India, social sciences as a whole have low priority. These are a few of the findings from World Social Science Report, 2010: Knowledge divides. Produced by the International Social Science Council (ISSC) and co-published with UNESCO, the Report is the first comprehensive overview of the field in over a decade. Hundreds of social scientists from around the world contributed their expertise to the publication. Gudmund Hernes, President of the ISSC, Adebayo Olukoshi, Director of the United Nations African Institute for Economic Development and Planning (IDEP), Hebe Vessuri, Director, Venezuelan Institute for Scientific Research (IVIC), and François Héran, Director of Research, National Institute for Demographic Studies (INED), France, are among the experts who presented the Report during its official launch at UNESCO Headquarters in Paris on 25 June 2010.
Based on an International Workshop held in New Delhi, India, this work should be of interest to all organizations and agencies interested in improved risk management in agriculture. In many parts of the world, weather and climate are one of the biggest production risks and uncertainty factors impacting on agricultural systems performance and management. Both structural and non-structural measures can be used to reduce the impacts of the variability (including extremes) of climate resources on crop production.
The Silk Road was the most traveled trade route for over 1,000 years until it was eclipsed by maritime trade. Whitfield presents composite stories of merchants, soldiers, artists, and princesses who traveled the route, and presents its history through their personal experiences.
ÔThe question Chris Gibson and his colleagues answer in this book is simple: ÒWhy is it not easy being green?Ó In 20 concise, focused and accessible chapters Ð from birthing to dying, from toilets to Christmas Ð they unveil the ambiguities, instabilities and paradoxes of affluent household living in the 21st century. In so doing, they temper the easy rhetoric of sustainable lifestyles with some authentic realities drawn from the affluent world. Earth system science is showing us the deep complexity of our material planet. This book brilliantly reflects back to us the complex materiality of our cultural lives.Õ Ð Mike Hulme, University of East Anglia, UK Contrary to the common rhetoric that being green is ÔeasyÕ, household sustainability is rife with contradiction and uncertainty. Households attempting to respond to the challenge to become more sustainable in everyday life face dilemmas on a daily basis when trying to make sustainable decisions. Various aspects of life such as cars, computers, food, phones and even birth and death, may all provoke uncertainty regarding the most sustainable course of action. Drawing on international scientific and cultural research, as well as innovative ethnographies, this timely book probes these wide-ranging sustainability dilemmas, assessing the avenues open to households trying to improve their sustainability. The authors engage critically, and constructively, with the proposition that households are a key scale of action on climate change. They confront dilemmas of practice and circumstance, and cultural norms of lifestyle and consumerism that are linked to troublesome environmental problems Ð and question whether they can be easily unsettled. The work also illuminates the informal and often unheralded work by households Ð frequently the poorest Ð in reducing their environmental burden. This important book is critical to understanding both the barriers to household sustainability and the ÔunsungÕ sustainability work carried out by householders. Containing a unique combination of science and cultural research, this fascinating book will appeal to researchers and students of environmental science, environmental studies, sustainability studies, climate change adaptation, geography, sociology, cultural studies, science and technology studies, as well as energy studies and housing research. Policy-makers in various levels of government working through sustainability problems, environmental educators, social planners and sustainability officers working for governments, will also find much to interest them in this unique book.
