The following Reprint, based on the Special Issue “Advances in Wastewater Treatment 2024”, compiles 12 papers (one Editorial, five review papers, and six original scientific papers) on innovative pollutant-removal technologies aimed at harnessing renewable energy from wastewater. Several papers included in this Special Issue address energy efficiency: the authors of one study assess the economic feasibility of a hydropower plant at the Toruń (Poland) treatment facility, while the authors of another study analyze energy use across three plants in southwestern Poland to propose strategies for reducing energy consumption and carbon footprint. In another study, the authors evaluate a novel Venturi-assisted confined tube aerator designed to lower aeration energy demand. The focus of three of the included papers is contaminant removal: synthesis and testing of Zn/Al layered double hydroxides for Congo red dye removal; assessment of low direct-current densities for phosphorus, nitrogen, and organic-compound removal in a sequential electrochemical reactor treating greenhouse wastewater; and evaluation of biochars and activated carbon for removing heavy metals from wastewater generated during soil remediation. The five review papers focus on renewable-energy integration for energy-self-sufficient municipal plants; advances in chemical coagulation and electrocoagulation; methanogenesis for biomethane production; solar-driven photocatalytic treatment using concentrator systems; and modeling and management strategies to optimize aeration energy use.

Intensive agriculture has generally resulted in higher productivity, but also in a trend towards decreasing levels of agro-biodiversity, which represents a key point in ensuring the adaptability and resilience of agro-ecosystems in the global challenge to produce more and better food in a sustainable way. The biodiversity of vegetable crops includes genetic diversity—both as species diversity (interspecific diversity) and as a diversity of genes within a species (intraspecific diversity) with regard to the vegetable varieties grown—and the diversity of agro-ecosystems (agro-biodiversity). The purpose of this Special Issue is to publish high-quality research papers addressing recent progress and perspectives on different aspects related to the biodiversity of vegetable crops. Original, high-quality contributions that have not yet been published, or that are not currently under review by other journals have been sought. The papers in this Special Issue cover a broad range of aspects and report recent research results regarding agro-biodiversity, which continues to be of significant relevance for both genetic and agricultural applications. All contributions are of significant relevance and could stimulate further research in this area.

The potential for climate change to cause vast human movement is a major global issue. Dominant approaches to climate-related migration take mobility as the starting point, exploring legal frameworks that tend to provide protection for migrants only after they move and overlooking measures that could help avoid forced movement in the first place. In contrast, Climate Change, Human Rights, and Adaptive Mobility provides a new conceptual and legal approach to human mobility in the context of climate change, one that seeks to compel and shape more proactive, anticipatory action. The book anchors its arguments in the international climate change regime, turning to obligations on adaptation found in the United Nations Framework Convention on Climate Change and the Paris Agreement. These obligations, though understudied and underutilized, have the potential to be a powerful legal tool. The book therefore seeks to lend them concrete legal meaning. It draws on international climate change and human rights law to weave together doctrinal analysis that considers treaty interpretation, regime interaction, and principles of environmental law with case studies in Bangladesh, the Pacific Islands, and the Sahel. At its core, the book argues that adaptation obligations require states to take measures to address foreseeable risks and ensure human rights. It further argues that developed countries that have contributed most to climate change have legal duties to support others in adapting to its effects, adding a collective dimension to the problem of climate change and mobility.

Flood risks worldwide are being exacerbated due to urbanisation and the consequences of climate change. This poses a challenge to traditional managerial approaches to flood risk management that try to be ‘fail-safe’. This book presents innovative and practical lessons on how to make flood risk management strategies ‘safe-to-fail’ and therewith more resilient. The book focuses on governance – rather than technical/managerial – approaches. As the book shows, new governance strategies are needed that ensure that flood risk management is not left to water managers alone. Various actors, including spatial planners, contingency agencies, NGOs and individual citizens, have a role to play in flood risk governance. Ten chapters assess different case studies from around the globe. These highlight the challenges and good practices related to learning, inter- and transdisciplinary cooperation, and debating and meeting the normative end-goals of flood risk governance. This book is essential reading for grounded scholars, reflexive policymakers and practitioners, and everyone else who is interested in contributing to more resilient and future-proof flood risk governance.

Global ecosystem changes are influenced by a combination of natural and anthropogenic factors. Ongoing changes in rainfall, temperature, and carbon dioxide in the atmosphere can affect natural or managed vegetation, such as forest, grassland, or farmland. Moreover, anthropogenic pressures, such as forest clearing, cattle grazing, increasing infrastructural development, intensive management, and expansion of cropland, can contribute to ecosystem degradation. This collection presents a wide range of studies examining natural and anthropogenic drivers in diverse ecosystems in Africa, Asia, and North America.

In recent years, bioeconomy strategies have been implemented and adapted internationally. In the bioeconomy, materials are to a certain extent circular by nature. However, biomaterials may also be used in a rather linear way. Lately, a transition towards a circular economy, a more restorative and regenerative economic model, is being promoted worldwide. A circular economy offers an alternative model aiming at “doing more and better with less”. It is based on the idea that circulating matter and energy will diminish the need for new input. Its concept lies in maintaining the value of products, materials, and resources for as long as possible and at the same time minimizing or even eliminating the amount of waste produced. Focused on “closing the loops”, a circular economy is a practical solution for promoting entrepreneurial sustainability, economic growth, environmental resilience, and a better quality of life for all. The most efficient way to close resource loops is to find value in the waste. Different modes of resource circulation may be applied, e.g., raw materials, by-products, human resources, logistics, services, waste, energy, or water. To that end, this Special Issue seeks to contribute to the circular bioeconomy agenda through enhanced scientific and multidisciplinary knowledge to boost the performance efficiency of circular business models and support decision-making within the specific field. The Special Issue includes innovative technical developments, reviews, and case studies, all of which are relevant to green, closed-loop, circular bioeconomy.

This book brings together recent research related to urban resilience, in particular, taking into account climate change impacts and hydrological hazards. Due to the complexity of our cities, which are vulnerable and continuously evolving systems, urban resilience should be considered as a transversal and multi-sectorial issue, affecting different urban services, several hazards, and all the steps of the risk management cycle. Within this context, the different pieces of research that form this book deal with the topics of multi-risk and urban resilience assessment, analysis of cascading effects, and the proposal and prioritization of adaptation measures and strategies to cope with climate-related hazards through multi-criteria analysis.

This volume examines the applicability of nature-based solutions in ecological restoration practice and in contemporary landscape architecture by bringing together ecology and architecture in the built environment. Green infrastructure is used to address urban challenges such as climate change adaptation, disaster risk reduction, and stormwater management. In addition, thermal comfort nature-based solutions reintroduce critical connections between natural and urban systems. In light of ongoing developments in sustainable urban development, the goal is a paradigm shift towards a landscape that restores and rehabilitates urban ecosystems. The ten contributions to this book examine a wide range of successful cases of designing healthier, greener and more resilient landscapes in different geographical contexts, from the United States of America and Brazil, through various European regions, to Singapore and China. While some chapters attempt to conceptualize the interconnections between cities and nature, others clearly have an empirical focus. Therefore, this volume provides a rich body of work and acts as a starting point for further studies on restoration of ecosystems and integrative policies such as the United Nations Sustainable Development Goals.

For a long time, the entry point for most communities and decision makers concerned about climate change was to ask, “what does the science tell us is going to happen?” Consequently, even though some effort was made to bring social and policy sciences to bear with the climate services enterprise, the demand for technological advances such as downscaled climate model projections and climate impact science drove much of the climate services agenda during its first decade and a half. By the 2000s, ‘users’ of climate information were becoming more sophisticated, and demand-driven innovations began to be recognized in peer-reviewed discussions of climate services; nevertheless, most authors continue to privilege a top-down, science-first flow of knowledge production and innovation. Entitled “Sustainability and Climate Services: Critique, Integration, and Reimagination,” the purpose of this Special Issue of Sustainability is to empower unconventional thinking in the hopes of accelerating the relevance of climate services at a time when communities at all levels are pursuing programs of adaptation, resilience, and sustainability. It is our hope that this Special Issue will provide outside-the-box, but constructive, critique to help support the basis for a ‘next generation’ of weather- and climate-related information products and services.

The Anthropocene, the time of humans. Never has human influence on the functioning of the planet been greater or in more urgent need of mitigation. Climate change, the accelerated warming of the planet’s surface attributed to human activities, is now at the forefront of global politics. The agriculture sector not only contributes to climate change but also feels the severity of its effects, with the water, carbon and nitrogen cycles all subject to modification as a result. Crop production systems are each subject to different types of threat and levels of threat intensity. There is however significant potential to both adapt to and mitigate climate change within the agricultural sector and reduce these threats. Each solution must be implemented in a sustainable manner and tailored to individual regions and farming systems. This Special Issue evaluates a variety of potential climate change adaptation and mitigation techniques that account for this spatial variation, including modification to cropping systems, Climate-Smart Agriculture and the development and growth of novel crops and crop varieties.

The papers included in this Special Issue tackle multiple aspects of how cities, districts, and buildings could evolve along with climate change and how this would impact our way of conceiving and applying design criteria, policies, and urban plans. Despite the multidisciplinary nature of the collection, some transversal take-home messages emerge: • Today’s energy-efficient paradigms may lose their virtuosity in the future unless accurate estimates of future scenarios are used to design modelling platforms and to inform legislative frameworks; • Acting at the local scale is key. Future climate change adaptation will be implemented at the local level. Overlooking regional and local specificities will contribute to inaccurate and inefficient action plans. As such, the smaller scale will become vital in predicting future urban metabolic rates and corresponding comfort-driven strategies; • Energy poverty, heat vulnerability, and social injustice are emerging as critical factors for planning and acting for future-proof cities on par of micro- and meso-climatological factors; • Given that the impacts of climate change will persist for many years, adaptation to this phenomenon should be prioritized by removing any prominent barrier and by enabling combinations of different mitigation technologies. These topics will receive a global reach in few decades, since also developing and underdeveloped countries are starting their fight against local climate change, with cities at the forefront.

Global population growth is urban growth and, therefore, most of the water-related challenges and solutions reside in cities. Unless water management and water governance processes are significantly improved within the next decade or so, cities are likely to face serious and prolonged water insecurity, urban floods, and/or heat stress, which may result in social instability and, ultimately, massive migration. Aging water infrastructure, one of the most expensive infrastructures in cities, is a relevant challenge in order to address Sustainable Development Goal (SDG) 6: clean water and sanitation, SDG 11: sustainable cities and communities, and SDG 13: climate action. The choice of good governance arrangements has important consequences for economic performance, for the well-being of citizens, and for the quality of life in urban areas. The better governance arrangements work in coordinating policies across jurisdictions and policy fields, the better the outcomes. Rapidly-changing global conditions will make future water governance more complex than ever before in human history, and expectations are that water governance and water management will change more during the next 20 years compared to the past 100 years. In this Special Issue of Water, the focus will be on practical concepts and tools for water management and water governance, with a focus on cities.

There is pressing evidence of phenomena, linked to meteorology and climate, which are modifying their temporal occurrence and which have a very evident impact on the safety and health of populations residing in cities. The urban problem at the beginning of the second set of twenty years of the new century requires a complete rethinking of the way of aggregation of man who, today, represents a large part of the world population due to increasingly accelerated urbanization processes over time. The human being has become a citizen, and within the city limits, he tries to develop his life expectancy by seizing opportunities from this. This search for well-being, understood as a complete state of man, at once physiological and psychological and social, can be thwarted by an urban structure that is not functionally capable of providing answers. The climate problem exacerbates this problem by strongly stressing the contradictions of living. Science, technology, and politics are today able to give answers if applied wisely in a joint effort, in a unit of language. This book proposes several solutions that can be implemented today, ranging from a full understanding of phenomena to adaptation policies for solving problems. The most pressing invitation is addressed precisely to politics to make cities more resilient and safe.

The Rio Declaration of 1992 and its agenda for action in the twenty first century—Agenda 21—were bold attempts at steering the nations in the world in the direction of ecologically sustainable development, a direction including social and environmental justice on a global scale. It did not take long, however, when the meaning of the word ’sustainable’ became diluted, sometimes even in the direction of an empty 'sustainababble´. Thus, what we see today is a huge variety of more or less scholarly based ‘sustainability’ imaginaries stating what the major problems facing humanity are represented to be and how they should be acted upon by science, economy, politics, and in everyday life. In other words, 'sustainability' is not enough. To evade the impression that the word may simply encourage the sustaining of an unjust status quo and that everyone has common interests in 'sustainable urban development' research and policy practice have to unmask the real conflicts of interest hidden behind the use of slippery language.
