This work becomes with methodological rigor a part of the innovative proposals for the characterization of the areas at risk of desertification. The complexity of the phenomenon of desertification, which involves extended surfaces in all continents, is one of the most alarming processes of the environmental degradation of our Planet and threatens the health and the living conditions of over a billion of persons. The food crisis, in continuous increase, ask for the world of research to urgently supply reassuring solutions concerning the acquisition of indicators, which are easy to monitor and concur to control the phenomenon in order to fight its acceleration. The constant but different combination that determines the diffusion of deserti- cation in the territories, attributable mostly to climatic changes and the activities of the man, makes our job challenging and complicated, since it varies from region to region. We are aware of all this and therefore we think that the methodological approach of survey of the data is an extremely important element to locate of the phenomenon and to monitor its course. This work, which is characterized for its multi-disciplinary approach, suggests solutions that we wish will quickly find concrete applications at international level.

Land Degradation and Desertification: Assessment, Mitigation, and Remediation reports research results in sustainable land management and land degradation status and mitigation in 36 countries around the world. It includes background papers with continental and international perspectives dealing with land degradation and desertification studies. The book assembles various topics of interest for a large audience. They include carbon sequestration and stocks, modern techniques to trace the trends of land degradation, traditional and modern approaches of resource-base conservation, soil fertility management, reforestation, rangeland rehabilitation, land use planning, GIS techniques in desertification risk cartography, participatory ecosystem management, policy analyses and possible plans for action. Various climatic domains in Africa, Asia, Europe and The Americas are covered. The book will be of interest to a variety of environmental scientists, agronomists, national and international policy makers and a number of organizations dealing with sustainable management of natural resources.

Biological and Environmental Hazards, Risks, and Disasters provides an integrated look at major impacts to the Earth's biosphere. Many of these are caused by diseases, algal blooms, insects, animals, species extinction, deforestation, land degradation, and comet and asteroid strikes that have important implications for humans. This volume, from Elsevier's Hazards and Disasters Series, provides an in-depth view of threats, ranging from microscopic organisms to celestial objects. Perspectives from both natural and social sciences provide an in-depth understanding of potential impacts. - Contributions from expert ecologists, environmental, biological, and agricultural scientists, and public health specialists selected by a world-renowned editorial board - Presents the latest research on damages, causality, economic impacts, fatality rates, and preparedness and mitigation - Contains tables, maps, diagrams, illustrations, and photographs of hazardous processes

This work provides insights into the physical and human geography of Sardinia, the second largest Mediterranean island, with its complex, varied, changing and often hidden features. The title, “Surrounded by Water”, recalls the identity of a land whose coastlines and surrounding seas have symbolically represented social, economic, political, cultural bridges or walls, meeting or colliding places, over its long and difficult history. Landscapes, seascapes and cityscapes are presented and analysed, together with other aspects, through a descriptive focus and original contributions provided by some local experts, in order to offer scholars and students across the globe a complex and multi-dimensional view of the reality of Sardinia through the lens of its geography. Each chapter of the book offers an in-depth and concise analysis of a specific topic, through the description of its characteristics and its current variations within the territory of the island. These descriptive aspects will be complemented with insights related to the research experiences and findings provided by the authors. This book will contribute to stirring new and modern interest about Sardinia, about further regional geographic studies, and about academic, scientific and cultural exchanges, among peoples and countries with both similar and different histories, identities, issues and hopes.

This book describes the risks, impacts, measures, actions and adaptation policies that have developed globally as a result of the severe impacts of global climate change. In-depth chapters focus on climate change assessment (CCA) in terms of vulnerabilities and reflection on the built environment and measures and actions for infrastructure and urban areas. Adaptation actions specific to developing countries such as Egypt are presented and illustrated. Global Climate change adaptation projects (CCAPs) in developing countries, in terms of their targets and performance, are presented and compared with those existing CCAPs in Egypt to draw learned lessons. Climate change scenarios 2080 using simulations are portrayed and discussed with emphasis on a case-study model from existing social housing projects in hot-arid urban areas in Cairo; in an effort to put forward an assessment and evaluation of current CCA techniques. This book helps researchers realize the global impacts of climate change on the built environment and economic sectors, and enhances their understanding of current climate change measures, actions, policies, projects and scenarios. Reviews and illustrates the impact of global climate change risks; Provides an understanding of global climate change risks in seven continents; Illustrates policies and action plans implemented at the global level and developing countries' level; Discusses climate change assessment and vulnerabilities with emphasis on urban areas; Presents measures and action plans to mitigate climate change scenarios by 2080.
