Book excerpt: Wastewater treatment and sludge disposal are important for protecting receiving rivers, lakes, and other water bodies, and vital for human health. Since excessive discharge may cause eutrophication and deterioration of aquatic systems, the US EPA and other national agencies have set guidelines for wastewater discharge standards. Conventional technologies are well developed and widely applied worldwide for wastewater treatment; however, new ideas and new technologies are gaining additional interest for the sake of water and energy reuse. While water is essential in arid regions, wastewater reuse and recycling have been playing an important role in human life. Although there are no universal standards for industrial and agriculture reuse, balancing wastewater treatment and public health protection presents challenges and opportunities.

This book was released on 2016-02-11 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land degradation caused by salinity and waterlogging is a global problem afflicting about one billion hectares and endangering the food security of at least 75 countries. Since the social, economic and environmental costs of on and/off-farm reclamation techniques are high, agroforestry is now emerging as a potential tool, not only for arresting salinity and waterlogging, but also for other environmental services like mitigating climate change, sequestering carbon and restoring biodiversity. This publication addresses the vital issues, principles and practices related to rehabilitation using agroforestry and includes many site-specific case studies from a number of the world’s typical catchments. Written by leading researchers, the book is a must, not only for scientists whose research interests lie in soil salinity, waterlogging and poor-quality waters, but also policy makers, environmentalists, students, and educationists alike. More importantly, it contributes to reversing the salinity trends and ensuring the livelihoods of resource-poor farming families living in these harsh agro-ecosystems.
Download or read book Innovative Saline Agriculture written by J.C. Dagar and published by Springer. This book was released on 2016-08-10 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 and waterlogged 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.

Download or read book Agroforestry written by Jagdish Chander Dagar and published by Springer. This book was released on 2018-04-06 with total page 869 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry (AF) is a dynamic, ecologically based, natural resources management system that, by integrating trees on farms, ranches, and in other landscapes, diversifies and increases production and promotes social, economic, and environmental benefits for land users. Further, it is receiving increasing attention as a sustainable land-management option worldwide because of its ecological, economic, and social attributes. Advances have been achieved by building on past research accomplishments and expanding AF’s stakeholder base, which now includes private/public partnerships, communities, ecologists, farmers, indigenous peoples, and policymakers in both temperate and tropical countries. AF has now been recognized as a valuable problem-solving approach to ensuring food security and rebuilding resilient rural environments. Recent studies have shown that more than 1 billion hectares of agricultural land have more than 10% tree cover. Of this area, 160 million hectares have more than 50% tree cover. Agricultural ecosystems can be further improved through AF to achieve environmental restoration, greater farm productivity, and key ecological services, including climate change mitigation and adaptation for improved rural livelihood. In fact, it is largely considered synonymous with climate smart agriculture and a remedy for many modern environmental challenges. Consequently, AF’s knowledge base is being expanded at a rapid rate, as illustrated by the increasing number and quality of scientific publications on various forms and different aspects of AF. This book offers state-of-the-art information on the fundamental concepts and history of AF and its evolution as a science, presenting a wealth of advanced research results and evaluations relating to different aspects of AF. Accordingly, it will be useful for a broad readership, including students, foresters, farmers, local communities, indigenous peoples, civil society institutions, media, policymakers and the general public.

Download or read book Plant Responses to Soil Pollution written by Pratibha Singh and published by Springer Nature. This book was released on 2020-10-01 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a vital support system for all life forms, and is directly or indirectly exposed to various pollutants and harmful chemicals. Any pollutant entering the soil system not only affects the quality of the soil, but also the plants and crops growing in it. Further, soil pollution has far-reaching impacts, since harmful chemicals can become biomagnified and enter the food chain, causing severe health concerns. Degraded soils can adversely affect various plant systems by creating biotic and abiotic stress, which increases the chances of biochemical and physiological disorders. Chronic diseases and lower yield have been reported as consequences of soil pollution. Drawing on decades of soil-related research, this book focuses on soil pollution, types of soil pollutants, and their impacts on plant physiological and biochemical systems, along with crop productivity. The book begins with a brief introduction to soil pollution and continues with a discussion of the different types and their effects, together with remediation methods. It highlights various sources of soil pollution such as herbicides, acidification, chemical fertilizers, sewage sludge, heavy metals, and radioactive pollutants. It also covers plant responses to combinations of pollutants, effects of pollutants on plant ultrastructure, interactions between pollutants and plant diseases, and interactions between pollutants and agricultural practices. In closing, it addresses the challenges involved in the restoration of degraded land, side effects of agricultural practices in the form of greenhouse gases, and strategies for mitigating these effects. Plant Responses to Soil Pollution offers an essential guide for students, environmental consultants, researchers and other professionals involved in soil and plant-related research.
