The book, ‘Changing Land Uses – Shrinking Streams and Carbon Sinks’, attempts at providing an overview of the calamitous consequences of deforestation on the world climate. Deforestation worldwide has been lowering the carbon sequestration potential of forests and increasing the concentration of CO2 in the atmosphere. The planet is already warmer by 1.10 C than the preindustrial era and as a result we are facing disastrous consequences in terms of frequent and destructive climatic catastrophes, namely, storms, sea surges, floods, droughts etc. Several perennial streams have become seasonal owing to deforestation in the catchments. With special reference to Karnataka’s Western Ghat forests, the book carries several investigative stories highlighting how notified and un-notified forests have been plundered for a variety of reasons. Diverse land tenures in Kodagu district of Karnataka and administration’s failure to regulate the rights and privileges are exploited by the nexus between politicians and bureaucrats. Without realizing the ecological services provided by forests, natural forests in different land tenures have been allowed to be degraded for quid pro quo. In addition, forests have been diverted for many developmental projects such as widening of roads, construction of reservoirs for power and irrigation, transmission of power, establishing rail connectivity etc. leading to changing land uses, disappearance of perennial streams and loss of carbon sinks. It is high time that states acted in conserving natural forests irrespective of the ownership, and the country as a whole must grow trees over 26 million hectares of degraded land by 2030 as pledged in the Paris climate accord of 2015.

The book, ‘FORESTS OF KARNATAKA - WHY AND HOW OF WHERE THEY ARE,’ attempts at understanding the diverse forests of Karnataka, their current status, and the primary factors that led to their transformation from their pristine (original and un-spoilt) states to the present states. Although formation of different types of forest depends fundamentally upon the general climatic and soil-related factors which vary from place to place, the present conditions of the forests are to a considerable extent reflective of the treatments meted out to them over the centuries. Past treatments of the forests include past forest management practices such as forest reservation, logging, clear-felling, raising plantations, forest protection, etc. as well as other biotic factors such as shifting cultivation, expansion of agriculture, heavy withdrawals of biomass, introduction of plantation crops, recurring fires, over-grazing, encroachments, etc. As a matter of fact, we now have different types of forest in different parts of the state depending upon the nature and intensity of the past interventions. The book while analysing various factors that resulted in degradation of a vast majority of the state’s forests has also suggested ways and means of how the existing forests can be protected from further degradation, enabling them to recover and rejuvenate.

The world faces huge challenges for water as population continues to grow, as emerging economies develop and as climate change alters the global and local water cycle. There are major questions to be answered about how we supply water in a sustainable and safe manner to fulfil our needs, while at the same time protecting vulnerable ecosystems from disaster. Water Resources: An Integrated Approach provides students with a comprehensive overview of both natural and socio-economic processes associated with water. The book contains chapters written by 20 specialist contributors, providing expert depth of coverage to topics. The text guides the reader through the topic of water starting with its unique properties and moving through environmental processes and human impacts upon them including the changing water cycle, water movement in river basins, water quality, groundwater and aquatic ecosystems. The book then covers management strategies for water resources, water treatment and re-use, and the role of water in human health before covering water economics and water conflict. The text concludes with a chapter that examines new concepts such as virtual water that help us understand current and future water resource use and availability across interconnected local and global scales. This book provides a novel interdisciplinary approach to water in a changing world, from an environmental change perspective and inter-related social, political and economic dimensions. It includes global examples from both the developing and developed world. Each chapter is supplemented with boxed case studies, end of chapter questions, and further reading, as well as a glossary of terms. The text is richly illustrated throughout with over 150 full colour diagrams and photos.

The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more quickly? As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods. With whatever portfolio of technologies the transition is achieved, eliminating the carbon dioxide emissions from the global energy and transportation systems will pose an enormous technical, economic, and social challenge that will likely take decades of concerted effort to achieve. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration will help to better understand the potential cost and performance of CDR strategies to inform debate and decision making as we work to stabilize and reduce atmospheric concentrations of carbon dioxide.

Based on a comprehensive study review by leading urban planning researchers, this investigative document demonstrates how urban development is both a key contributor to climate change and an essential factor in combating it -- by reducing vehicle greenhouse gas emissions.

A new approach to water-resources for researchers, professionals and graduate students, focusing on global sustainability and socio-ecological resilience to change.

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

This compilation of techniques, methodologies and scientific data arises from a four-year Italian research project, which took place at university research stations in Turin, Piacenza, Naples and Potenza. Soil Organic Matter (SOM) represents an active and essential pool of the total organic carbon on the planet. Consequently, even small changes in this SOM carbon pool may have a significant impact on the concentration of atmospheric CO2. Recent new understanding of the chemical nature of SOM indicates that innovative and sustainable technologies may be applied to sequester carbon in agricultural soils. Overall results of the project have been applied to develop an innovative model for the prediction and description, both quantitatively and qualitatively, of carbon sequestration in agricultural soils. This book provides experts in different areas of soil science with a complete picture of the effects of new soil management methods and their potentials for practical application in farm management.

Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. In 2008, urban population exceeded the rural population. In 2050, 70% of the world population will live in urban centers. The number of megacities (10 million inhabitants) increased from three in 1975 to 19 in 2007, and is projected to be 27 in 2025. Rapid urbanization is altering the ecosystem C budget. Yet, urban ecosystems have a large C sink capacity in soils and biota. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.
