Despite the strong economic growth of the last decades, our modern global society is facing the existential threat of climate change. It is now realized that the linear economic model is not sustainable in the long run and cannot sustain the life standards. The new circular economy approach that is already under discussion suggests the adjustment of our priorities and the re-orientation of the future infrastructure investments. In this context, we are looking for new, innovative and sustainable solutions to increase the resiliency of our societies, to protect and restore the ecosystems, and to maintain the necessary economic growth without further undermining the planet's boundaries. The well-being of coming generations will depend on our ability to adapt our economies to this challenge. In particular, transforming today's cities into sustainable cities is one of the main adaptations that will be necessary. A holistic approach looking at cities from a system's perspective is neededto achieve this goal.Nature-based solutions (NbS) serve exactly this ambitious and multi-factorial purpose due to their inherent ability not only to tackle climate change but also to provide a series of ecosystem services and social benefits. In the urban context, NbS can deal with main challenges such as urban heat islands, flooding, treatment of wastewater and runoff and food provision. At the same time, NbS can provide a series of ecosystem services beneficial for the environment and the society including clean water production, nutrient recovery, heavy metals retention and a broad range of plant-based materials. In the new circular economy paradigm, NbS can contribute to strategies for climate change adaptation and create a holistic resource management system for the urban biosphere.Thus, this book aims at providing a single reference that discusses the role and effectiveness of NbS in the urban environment and how these systems can contribute to the circular management of water, nutrients and resources towards resilient, sustainable and healthy cities. The scope of the book extends to various fields and disciplines such as the built environment, urban water and wastewater, resource recovery, urban farming, smart sensing, research and development, technology and innovation, society and governance. Research studies, pilot projects, and case studies are part of the book.

This book covers topics that addresses the global environmental issues, their challenges, and mitigation strategies for sustainable development. Some of the major challenges global environment is facing currently are global warming induced climate change because of which various extreme weather events such as flood, drought, cyclone, forest fires have increased. Industrialization with urbanization and human anthropogenic activities have caused detrimental effect on the environment resulting in environmental pollution (air and water pollution), deforestation, degradation of ecosystems, soil erosion, ground water depletion, drinking water scarcity, biodiversity loss, depletion of fossil fuels, etc. Therefore, it has become utmost necessary to switch to significant lifestyle stages along with conservation of natural resources for a sustainable environment. Sustainable environment may be defined as the practice of responsibly managing natural resources and protect overall ecosystem to support health and well-being of present and future generations. One of the major environment sustainability is the use of renewable sources of energy such as solar, wind, hydroelectric, and biomass which will reduce environmental pollution and also minimize resource misuse. At the same time, crop rotation, solid waste management, water treatment, wastewater treatment are some of the sustainable practices we must carry out for a sustainable environment. Hope, the content of the book gives an overview of recent developments, knowledge gaps related to new research areas related to environment and their future prospects.

This book contains detailed information about the traditional rainwater structures. Harvesting rainwater is becoming as a practical adaptation strategy for urban areas that are vulnerable to climate alteration. In the past, rainwater harvesting was more significant than it is today. Studies show that a variety of traditional and age-old rainwater gathering techniques were created or put into use in reaction to earlier climate change incidents. According to history, both floods and droughts were frequent occurrences in ancient India. Perhaps this explains why each region of the nation has its own traditional water gathering practices that are representative of the local physical and cultural diversity. All of these methods can be seen as a concept of harvesting rain whenever and wherever it falls. Water makes up 70.9 % of the Earth's surface, mainly in the form of oceans and seas. Water is found in modest proportions as 1.7 % groundwater, 1.7 % glaciers and ice caps in Antarctica and Greenland, vapour, clouds (ice and liquid water suspended in air), and 0.001% precipitation in the air. Evaporation, transpiration, evapo-transpiration, condensation, precipitation, root absorption, percolation, infiltration, base flow and runoff are processes that water goes through on its way to the sea.

Recycling is the need of the hour and it is an inevitable destination at the end of the life of any product. Today, recycling can happen at postindustrial and post-consumer states and the importance of recycled products in the market has gained significant importance. Recycled products dominate the array of sustainable products in today's context. Even though there are commercial implications for recycling, one of the very important and obvious reasons to go for recycling and to have recycled products is to have the benefits on environmental sustainability. It is highly important to assess the environmental footprints of recycled products and further improve the environmental benefits of such recycled products. This book presents five interesting chapters pertaining to the environmental footprints of various recycled products.

Waste management is a topical issue worldwide. In recent years, several requests have been made by citizens and associations to political decision-makers regarding the need for a significant improvement in waste management methods. Particularly considering the significant increase in awareness of social and environmental impacts and the economic consequences of non-virtuous waste management. There is growing attention on legislation and regulation's role in the waste sector. Regulation can help companies and citizens achieve a faster, more effective, and more efficient transition from a linear economy, based on the take-make-dispose paradigm, to a circular economy, in which the potential of waste as resources and secondary raw materials is exploited.This book is set in the wake of economic literature that tackles the transition from the linear to the circular economy. It focuses on the downstream stages of the waste management process (i.e. the waste treatment phase). In this regard, it is proposed a journey through the history of European waste legislation to study the waste sector's transition dynamics from a selfish and no longer sustainable economic model based on rampant consumerism to a far-sighted sustainable model addressing the well-being of future generations. Studying the changes in European waste regulations leads us to ask ourselves the following questions: how has waste collection changed in recent years? What are the new regulatory challenges that must be addressed to achieve the objectives of a circular economy? How successful has the EU legislation been in fostering the transition from a linear to a circular economy? Finally, has the European environmental legislation sprung a convergence process among European countries towards the circular economy, or has the definition of targets fuelled the already marked differences between EU countries?
