Urban Ecology covers the latest theoretical and applied concepts in urban ecological research. This book covers the key environmental issues of urban ecosystems as well as the human-centric issues, particularly those of governance, economics, sociology and human health. The goal of Urban Ecology is to challenge readers' thinking around urban ecology from a resource-based approach to a holistic and applied field for sustainable development. There are seven major themes of the book: emerging urban concepts and urbanization, land use/land cover change, urban social-ecological systems, urban environment, urban material balance, smart, healthy and sustainable cities and sustainable urban design. Within each section, key concepts such as monitoring the urbanization phenomena, land use cover, urban soil fluxes, urban metabolism, pollution and human health and sustainable cities are covered. Urban Ecology serves as a comprehensive and advanced book for students, researchers, practitioners and policymakers in urban ecology and urban environmental research, planning and practice.

The book is organized by waste type, including electronic, industrial and biomedical/hazardous, with each section covering advanced techniques, such as remote sensing and GIS, as well as socioeconomic factors, transnational transport and policy implications. Waste managers, environmental scientists, sustainability practitioners, and engineers will find this a valuable resource for addressing the challenges of waste management in the developing world.

There is high potential for waste management to produce energy and value-added products. Sustainable waste management based on a circular economy not only improves sanitation, it also provides economic and environmental benefits. In addition to waste minimization, waste-to-economy and waste-to-energy have become integral parts of waste management practices. A proper waste management strategy not only leads to reduction in environmental pollution but also moves toward generating sufficient energy for improving environmental sustainability in coming decades.

This book helps the readers get a holistic understanding of the emergence of biochar-nanocomposite research. The low and long-term exposure of persistent hazardous pollutants in environment is well known for damaging the water, soil, sediments, and living biota. Thus, it is a crucial step to eliminate these pollutants from environment regimes to prevent the on-site destruction or the transfer into the food chain. Biochar is a carbon-rich solid material generated through pyrolysis of biomass, and currently, it is covering the hotspot in environmental management of pollutants.  It is being utilized for the efficient immobilization and sorption of organic pollutants, heavy metals, dyes, improvement of soil redox conditions, aggregate stabilization, photocatalytic degradation, and for carbon sequestration. The fascinating properties like surface area, porous structures, functional groups, and mineral components turn it into suitable candidate for the removal of various class of pollutants from environmental matrices. Different reactions like sorption, reduction, precipitation, solidification, and degradation are mainly responsible for the effective cleaning of xenobiotics from environment through biochar application. However, rapidly evolving contaminants in the environment have made the remediation more complex, expensive, and challenging. In view of these aspects, the modification of biochar through the doping of nanometals/metal oxides/surfactants/ or chemical entities will result in modified biochar with high surface area, more functional entities, improved physical, chemical, thermal, and mechanical characteristics with more adsorptive sites. Inclusion of these exclusive properties can be done through magnetic modification, impregnation of nanometals/ metal oxides/surfactants, amination, acid/base reactions, steam activation, etc. The resulted biochar-based nanocomposites have demonstrated a vital role in remediation of persistent organic pollutants, radionuclei, and heavy metals through the various interaction mechanisms like surface complexation, π–π interaction, electrostatic interaction, hydrogen bonding, Fenton process, and photocatalytic degradation. Currently, advanced research work has been carried out for the designing of modified composites of biochar to achieve maximum removal efficiency, reusability, biotoxicity, and sustainability. Hence, for selective removal of pollutants through designed biochar surface with the focused experimentation toward optimization of feedstocks, process variables, appropriate impregnation of nanomaterials, interaction with secondary pollutants, physical environment, longevity, and regeneration will definitely pave the way for safe and commercial application of biochar-based nanocomposites.

This book provides a basic understanding and state-of-the-art of urban metabolism. Urban centres are increasingly challenged by population increase and the resultant environmental concerns including the urban sprawl and climate change. Different patterns of urbanization contribute to the changing climate via. differences in their urban metabolism represented by energy and matter. Urban metabolic studies in terms of energy and material inflows, outflows, and stocks can be associated with traditional evaluation techniques to help assess the magnitude and potential effects of variety of environmental challenges the world is facing today. Urban centres are critical real time observatories that indicate the impact anthropogenic activities have on global biogeochemical cycles. Urban processes have significant and lasting impacts on the global carbon budget. The technological and infrastructural advancements have fuelled an increase in urban inputs and outputs of material and energy. Therefore, more sustainable approaches need to be adopted in changing scenarios for urban planning, particularly for sustainable resource utilization and better waste management practices. The book emphasises on the sustainability in urban metabolism, sustainable urban planning, ecosystem services, and disaster resilience to provide an interdisciplinary understanding of urban metabolism. The book also identifies an urgent need to develop new methodological approaches for real time and reliable evaluation of urban metabolism.

The proposed book presents the current state of knowledge about the processes, parameters, and phenomena that influence the fate of neonicotinoids in soil-water systems (i.e., soil and groundwater), as well as their effects and mitigation measures, and identifies existing knowledge gaps. Furthermore, groundwater/surface water interactions, as well as sorption, biodegradation, and chemical transformations of neonicotinoids in the soil and leaching to the groundwater, are highlighted, as they determine their further migration from sources, through soils to groundwater systems, and then to other environmental compartments, posing ecological and human risks. The ecological risks of neonicotinoids are highlighted in a separate section with special emphasis on the impacts on biological diversity.
