Ecosystems have been suffering accelerated destruction and modification of their original characteristics, resulting in species extinction and loss of populations still not known to science. This panorama, known as the “biodiversity crisis”, is defined by an increase of about a thousand times in species extinction rates, mainly caused by anthropogenic activity. Therefore, efforts to improve our knowledge of the systematics, taxonomy, ecology, and distribution of species play a key role in species conservation. Among all habitats, freshwaters, which cover about 1% of Earth's surface, are the most threatened. Approximately 3/4 of wetlands were lost during the 20th century, 1/3 of freshwater vertebrate species are threatened with extinction, and freshwater vertebrate populations are declining much more rapidly than terrestrial and marine populations. Freshwaters are home to more than 10% of all known species, including 30% of all vertebrates, a group whose populations have declined more than 80% over the past 50 years. The conservation of freshwater biodiversity and environments is critical for humanity as it represents the main source of drinking water, and food, being also crucial to agronomy and livestock. Within the rapidly degrading context of freshwaters, this Research Topic aims to create an overview of different approaches that contribute to freshwater conservation and policies at a global level. Studies regarding distinct groups of freshwater fauna and flora and aspects related to the implications of taxonomy, ecology, evolution, and biogeography for the conservation of freshwaters are welcome. The goal of this Research Topic is to summarize the status of freshwater biodiversity and propose the next steps and basic guidelines for habitat and species conservation. This Research Topic is a continuation of the first edition, and it welcomes Original Research Articles and Review Articles based on both traditional and modern methods focusing on distinct aspects of global freshwater fauna and flora. Highlights of this topic include but are not limited to, the following points focused on freshwater fauna and flora: • Species delimitation and DNA barcoding • Environmental DNA (eDNA) • Integrative taxonomy • Biogeography and areas of endemism • Invasive species • Regional species inventories importance • Anthropogenic impacts and threats to Freshwater environments • Importance of scientific collections for conservation • Freshwater environments ecology • Climate changes • Identification and delimitation of priority areas for conservation

Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.

The Global Water System in the Anthropocene provides the platform to present global and regional perspectives of world-wide experiences on the responses of water management to global change in order to address issues such as variability in supply, increasing demands for water, environmental flows and land use change. It helps to build links between science and policy and practice in the area of water resources management and governance, relates institutional and technological innovations and identifies in which ways research can assist policy and practice in the field of sustainable freshwater management. Until the industrial revolution, human beings and their activities played an insignificant role influencing the dynamics of the Earth system, the sum of our planet‘s interacting physical, chemical, and biological processes. Today, humankind even exceeds nature in terms of changing the biosphere and affecting all other facets of Earth system functioning. A growing number of scientists argue that humanity has entered a new geological epoch that needs a corresponding name: the Anthropocene. Human activities impact the global water system as part of the Earth system and change the way water moves around the globe like never before. Thus, managing freshwater use wisely in the planetary water cycle has become a key challenge to reach global environmental sustainability.

Continuous improvement of approaches for dam design engineering and groundwater resource characterization is needed to respond to new environmental challenges brought upon by climate changes and population growth. The book is divided into two sections. The first section deals with dam designs’ technical, socio-economic, and sustainability aspects. The second section covers technical aspects of groundwater resource characterization. We believe the book will be a valuable resource for hydrology, civil engineering, and groundwater professionals.

This illustrated report sets out a global review of the state of the world's freshwater resources, based on the collective work of 24 United Nations agencies, following on from the conclusions of the first UN World Water Development Report 'Water for People, Water for Life' published in 2003 (ISBN 9231038818). This second edition discusses progress towards the water-related targets of the UN Millennium Development Goals and examines a range of key issues including population growth and increasing urbanisation, changing ecosystems, food production, health, industry and energy, as well as risk management, valuing and paying for water and increasing knowledge and capacity. It contains 16 case studies which consider key challenges in water resource management and makes a number of recommendations to guide future action and encourage sustainable use, productivity and management of our increasingly scarce freshwater resources.

The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

This short open access book investigates the role of renewable energy in East Africa to provide policy-relevant inputs for the achievement of a cost-effective electrification process in the region. For each country, the authors review the current situation in the domestic power sector, adopt a GIS-based approach to plot renewable energy resources potential, and review currently planned projects and projects under development, as well as the key domestic renewables regulations. Based on such information, least-cost 100% electrification scenarios by 2030 are then modelled and comparative results over the required capacity additions and investment are reported and discussed. The authors also inquire into some of the key technological, economic, policy, cooperation, and financing challenges to the development of a portfolio of renewables to promote energy access in a sustainable way, including a discussion of the challenges and opportunities that might stem from the interaction between local RE potential and natural gas resources currently under development in the region. To conclude, policy recommendations based on the book’s results and targeted at international cooperation and development institutions, local policymakers, and private stakeholders in the region are elaborated.
