Increased environmental and energy concerns have renewed global interest in raw earth as a building material. Low-energy requirements, low-cost, high availability at construction sites, and favorable engineering properties make (EBMs) an attractive alternative to conventional cement-based construction materials. Though the use of native binders to improve soil properties has garnered attention in recent literature, the available knowledge has not been covered in a single document. This book highlights the key soil properties that determine the mechanical performance of earthen building materials, importance of unsaturated soil mechanics in the engineering behavior of earthen building materials, the different types of stabilizers used to improve the engineering performance of earthen building materials including the use of select native binders, the characteristics of compressed earth blocks stabilized with cement and cement + wood ash additives and the improvement in the engineering properties of adobes stabilized with plant fibers and cow dung.

This volume unravels the underlying power relations that are masked in the present discourse of ecological sustainability and conflicts over natural resources. Current discussions on environment emphasise the use and abuse of the environment in various ways. This book looks at the inter-linkages of discourse, resources, risk and resistance in the contemporary neoliberal world. While exploring the experiences of neoliberalisation of nature in India, it brings out the intersections of conservation and management, science and gender, community politics and governance policies.The volume highlights the cultural politics of resistance from multiple sites and regions in India in the recent context (be it land, water, forest, flora or fauna or urban commons). It discusses the ways in which environmental issues have come up and been appropriated, while examining the role of the State and actors such as corporates, traders, consultants, ecotourism companies, green activists and consumers, and consequences of 'green' appropriation and the 'growth' story. The major themes of the volume are the interrelations of nature, culture and power; neoliberal governance and the environment; access to and use and management of land, natural resources and environment; community politics and livelihoods; marginalised groups and local communities; marketisation and the environment; and new forms of re-appropriation and resistance.This book will be of great interest to students and researchers in sociology, environmental studies, environmental history, environmental anthropology, political ecology, political science, geography, law and human rights, economics and development studies as well as to environmental activists, policy makers and those in media and journalism.

Bacterial Biogeochemistry: The Ecophysiology of Mineral Cycling, Fourth Edition discusses the influence of bacterial activity on the chemical environment of the biosphere. Following the success of previous editions, this update focuses on bacterial metabolism and its relevance to the environment, including the decomposition of soil, food chains, nitrogen fixation, assimilation, and reduction of carbon nitrogen and sulfur, and microbial symbiosis. All chapters have been revised and brought up-to-date in light of the many advances and discoveries that have taken place during the last decade. The scope of the new edition has broadened to provide a review of the processes and phenomena that are relevant for global change feedback loops and advances in bacterial biogeochemical cycles.

This book highlights recent advances in the discipline of biogeochemistry that have directly resulted from the development of critical zone (CZ) science. The earth's critical zone (CZ) is defined from the weathering front and lowest extent of freely circulating groundwater up through the regolith and to the top of the vegetative canopy. The structure and function of the CZ is shaped through tectonic, lithologic, hydrologic, climatic, and biological processes and is the result of processes occurring at multiple time scales from eons to seconds. The CZ is an open system in which energy and matter are both transported and transformed. Critical zone science provides a novel and unifying framework to consider those coupled interactions that control biogeochemical cycles and fluxes of energy and matter that are critical to sustaining a habitable planet.  Biogeochemical processes are at the heart of energy and matter fluxes through ecosystems and watersheds. They control the quantity and quality of carbon and nutrients available for living organisms, control the retention and export of nutrients affecting water quality and soil fertility, and influence the ability for ecosystems to sequester carbon. As the term implies, biogeochemical cycles, and the rates at which they occur, result from the interaction of biological, chemical, and physical processes. However, finding a unifying framework by which to study these interactions is challenging, and the different components of bio-geo-chemistry are often studied in isolation.  The authors provide both reviews and original research contributions with the requirement that the chapters incorporate a CZ framework to test biogeochemical theory and/or develop new and robust predictive models regarding elemental cycles. The book demonstrates how the CZ framework provides novel insights into biogeochemistry.

This book summarizes the outcomes of research results based on field works and recent studies related to soil cover of the dried Aral seabed in Kazakhstan. The purpose of the work was to conduct a comprehensive assessment of the current state of the soil cover in the dried bed of the Aral Sea in order to study the processes that are occurring in the local soils as a result of anthropogenic impacts inducing soil degradation and desertification (e.g., soil salinization and deflation). Additionally, the book analyzes morphological characteristics and chemical-physical properties of soils in the dried bottom of the Northern Aral Sea in order to know how material properties can be transported during soil deflation in dust/sand/salt storms in the region, as well as to identify changes in long-term dynamics of aridization and climatic parameters such as temperature, precipitation and evapotranspiration in the Aral Sea region.The novelty of this research is reflected in the latest information on the vertical and spatial distributions of soils and their chemical properties in the region containing the dried bed of the Aral Sea in Kazakhstan. Consequently, an updated soil map (soil salinization and salinization degree, land degradation) of the seabed was obtained according to the collected field data and satellite-derived images such as those recorded by Landsat-8. The book is mainly addressed to scientists and researchers who study soil cover in the dried Aral Seabed and its region, as well as soil degradation and desertification in the dried lake playas and aridization in other arid regions. The book will also be useful for students and planners who feel responsible for the sustainable development and sustainable use of natural resources in Central Asian countries.

The book provides a unique analysis of current air pollution in Germany by correlating results from chemical transport modelling and accumulation monitoring by moss.Results of most recent modelling of atmospheric concentration and deposition of the metal elements Cd, Hg and Pb are compared with the results of technical measurements and bioindication with mosses. These modelling results with status 2020 have a higher spatial resolution of 0.1° x 0.1° than the modelling results valid up to then (50 km x 50 km). This leads to partly slightly higher correlations between the findings of the modelling and those of the moss monitoring. In this study, descriptive and correlation-statistical parameters are calculated, results and recommendations drawn described. A statistically adequately deepened analysis and evaluation of the highresolution modelling results requires additional methodological tools, which are outlined in summary. It is particularly important to link the exposure data from modelling, technical measurements and the findings from moss monitoring with information on the receptors, the ecosystem types. This is the only way to ensure that the results of the present project contribute to a more differentiated assessment of the impacts on ecosystems from atmospheric heavy metal deposition than has been the case to date, thus enabling a targeted further development of risk assessments for German

Many politicians, industry leaders, and even some scientists advocate replacing carbon-based energy carriers with other elements and mineral-based solutions. But in The Decarbonization Delusion, Andrew Moore argues that we should instead look to the biological Earth as a model for how humans can use carbon sustainably. Moore challenges the idea that the race to decarbonize is good for the planet. In fact, he argues that doing so could lead us further down the road to environmental disaster. Heavily researched, The Decarbonization Delusion uses sound reasoning and solid data to demonstrate why carbon should continue to play a critical role in our energy economies.
