Buch. Zustand: Neu. Neuware -The land degradation due to salinity and waterlogging is a global phenomenon, afflicting about one billion hectares within the sovereign borders of at least 75 countries. Besides staring at the food security, it has far reaching and unacceptable socio-economic consequences since a large proportion of this land is inhabited by smallholder farmers. The anthropogenic-environmental changes and the climate change are further adding to the problem of salinity and waterlogging. The phenomenon of sea-level rise will bring more areas under waterlogged salinity due to inundation by sea water. Thus, dealing with the salinity in reality is becoming a highly onerous task owing to its complex nature, uncertainty and differential temporal and spatial impacts. Nevertheless, with the need to provide more food, feed, fuel, fodder and fiber to the expanding population, and non-availability of new productive land, there is a need for productivity enhancement of these lands. In fact, the salt-affected andwaterlogged lands cannot be neglected since huge investments have been made throughout the world in the development of irrigation and drainage infrastructure. The social, economic and environmental costs being high for theon-and/off-farm reclamation techniques, saline agriculture including agroforestry inculcated with modern innovative techniques, is now emerging as a potential tool not only for arresting salinity and waterlogging but for other environmental services like mitigate climate change, sequester carbon and biodiversity restoration. This publication attempts to address a wide range of issues, principles and practices related to the salinity involved in rehabilitation of waterlogged saline soils and judicious use of saline waters including sea water. Many of the site specific case studies typical to the saline environment including coastal ecologies sustaining productivity, rendering environmental services, conserving biodiversity and mitigating climate change have been described in detail. Written by leading researchers and experts of their own fields, the book is a must, not only for salinity experts but also for policy makers, environmentalists, students and educationists alike. More importantly, it contributes to reversing the salinity trends and teaches to sustain with salinity ensuring the livelihood of resource-poor farming families leaving in harsh ecologies including coastal areas which are more vulnerable to climate change.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 532 pp. Englisch.

Buch. Zustand: Neu. Neuware - Today, agroforestry ranks high among the significant land-management initiatives that have undertaken the world over the past few decades. Indeed, it is now recognized as an important approach to ensuring food security and rebuilding resilient rural environments. Recent studies have shown that more than one billion hectares of agricultural land have more than 10% tree cover. Of this, 160 million hectares have more than 50% tree cover. Agricultural ecosystems can be further improved through agroforestry to ensure environmental restoration, greater farm productivity, and realization of ecological services, including climate change mitigation and adaptation for improved rural livelihood. Now, agroforestry is considered synonymous to climate smart agriculture and a remedy for many modern environmental challenges, and acts as a mitigating process for climate change. Consequently, the knowledge base of agroforestry is being expanded at a rapid rate as illustrated by the increasing number and quality of scientific publications of various forms on different aspects of agroforestry. Making full and efficient use of this upsurge in scientific agroforestry is both a challenge and an opportunity to the scientific community, particularly in the scenario of climate change. In order to help prepare themselves better for facing the challenges and seizing the opportunity, agroforestry scientists need access to synthesized information on multi-dimensional aspects of scientific agroforestry. It is believed that widespread scaling-up of agroforestry innovations during the next decade will greatly facilitate the success of global commitments and conventions such as the UN Millennium Development Goals, Convention on Biological Diversity, Framework on Climate Change, and the Convention to Combat Desertification. This book will be useful for engaging more stakeholders, including students, foresters, farmers, local communities, indigenous people, civil society institutions, the media, private sectors, scientists (working in the fields of Agroforestry, Forestry, Life Sciences, Animal Husbandry & Dairy, Social Science, Food Science and Environmental Sciences), policymakers, leaders, and the public.

From the foreword by Dr. M.S. Swaminathan: The Andaman and Nicobar group of islands are the only Indian territory which still basks in its pristine glory. The archipelago is endowed with various maritime ecosystems like evergreen semi evergreen and deciduous forests mangroves grasslands and pastures. The rain forests exhibit majestic growth in multi tier canopies with rich biological wealth. Even now new species are being discovered from the forests of these islands. Recently the scientists of the Botanical Survey of India discovered a new species Oryza indandamanica. Yet there have been dismal efforts to catalogue the plant resources of the islands. This backlog will now be covered by the book Plant Resources of Andaman and Nicobar Islands written by J.C. Dagar and N.T. Singh. They have served the islands for a number of years and their experience of the territory is reflected in the compilation of the plant resources unique ecosystems soils tribal population cropping patterns floristic analysis and utilisation of plant species. The authors have enumerated over 2400 species of vascular plants out of which 296 taxa are reported to be endemic to these islands. The utilisation of plants in medicine food fibre timber and fodder by different tribal groups is an interesting and important information compiled by the authors. The information on different economic plants will be of abiding interest to those interested in plant resources and agriculture. The book begins with a description of the islands their geology topography climate soils the people and the resources. Another important feature is a description of agroecosystems cropping patterns relevance of agroforestry for the islands weeds of crops and their distribution and management. The authors have compiled the information from diverse sources to make the book comprehensive.
