Book Description
Natural and Semi-Natural Grassland Ecosystems (NSG) represent high-value biodiversity hotspots for biodiversity of the European continent, as well as an invaluable cultural heritage forged through millennia of human-nature interactions. While pristine natural European grasslands result mainly from constrained specific climatic and soil conditions, semi-natural grasslands largely result from the activities of humans and their livestock (e.g. grazing, mowing, burning) during millennia of low-intensity land use. European NSG, their biodiversity, and the cultural heritage they represent are highly threatened since the beginning of the 20th century in a context of multifactorial global change including environmental dimensions (climate change, habitat fragmentation, pollution, biological invasions) and land-use changes with the accelerating of socio-economic evolution of agricultural practices (intensification or abandonment) and urbanization.

Book Description
This book is a pioneer attempt to bring forward the first synthesis on the most diverse and threatened mountain top vegetation of South America, the rupestrian grasslands. It brings to light the state of the art information on this ecosystem geology, soil formation and distribution, environmental filters that lead to biodiversity, species interactions and their fine tuned adaptations to survive the harsh mountain environment. The human dimensions of the rupestrian grassland are also addressed, including the anthropogenic threats that may irreversibly impact biodiversity and ecosystem services. The book also highlights the ongoing studies on ecological restoration and first attempt to model the impacts of climate change on its speciose biota.

Book Description
Encyclopedia of the Anthropocene, Five Volume Set presents a currency-based, global synthesis cataloguing the impact of humanity’s global ecological footprint. Covering a multitude of aspects related to Climate Change, Biodiversity, Contaminants, Geological, Energy and Ethics, leading scientists provide foundational essays that enable researchers to define and scrutinize information, ideas, relationships, meanings and ideas within the Anthropocene concept. Questions widely debated among scientists, humanists, conservationists, politicians and others are included, providing discussion on when the Anthropocene began, what to call it, whether it should be considered an official geological epoch, whether it can be contained in time, and how it will affect future generations. Although the idea that humanity has driven the planet into a new geological epoch has been around since the dawn of the 20th century, the term ‘Anthropocene’ was only first used by ecologist Eugene Stoermer in the 1980s, and hence popularized in its current meaning by atmospheric chemist Paul Crutzen in 2000. Presents comprehensive and systematic coverage of topics related to the Anthropocene, with a focus on the Geosciences and Environmental science Includes point-counterpoint articles debating key aspects of the Anthropocene, giving users an even-handed navigation of this complex area Provides historic, seminal papers and essays from leading scientists and philosophers who demonstrate changes in the Anthropocene concept over time

Book Description
This book offers perspectives on how to develop a sustainable global balance of urbanization, land-use intensification, land abandonment, and multifunctional cultural landscapes. The focus is on the latter by describing the large variety of traditional cultural landscapes having evolved through centuries or even millennia by the use of the natural, terrestrial and aquatic resources. Those cultural landscapes encompass pasture, agroforestry, terraced, irrigation, coastal, monastic, and sacred landscapes as well as lake-, river-, and saltscapes. The restoration of low-input land-use systems which often carry a high biodiversity on the species, ecosystem, and landscape level as well as agrobiodiversity and agrodiversity is outlined. The restoration of multifunctional and diverse landscapes, however, is not only an ecological issue but encompasses many socio-economic aspects such as e.g., the revitalization of villages, eco-tourism, healthy food production, infrastructure, and rural-urban partnerships. Global environmental problems, which are related to urbanization and the intensification of the use of land and water resources are comprehensively outlined. Land abandonment which occurs on all continents is qualitatively and quantitatively assessed and the consequences for natural and cultural heritage loss is highlighted. With the presentation of current rural development and landscape conservation strategies on the national as well as international level, the topic reflects the high significance of environmental policy on the global scale. The global implementation of natural and cultural heritage conservation is, for example, given by the UNESCO World Heritage Sites, National Parks, Biosphere Reserves, Globally Important Agricultural Heritage Sites, High Nature Value Farmland, and the Satoyama initiative. However, also the “every-day” landscapes can contribute to biodiversity and strong sustainability. This comprehensive compendium, based on about 4,000 references of scientific studies, literature reviews, project reports, and environmental policy papers is thought for all students, scholars, and stakeholders from multifaceted disciplines, interested in multifunctional cultural landscapes and how traditions and innovation on the landscape level can be merged for a sustainable future on our planet. Case studies from all over the world are presented which can be used in Higher Education or to demonstrate the numerous approaches of sustainable rural development.

Book Description
This book begins with a brief account of the extraordinary sequence of events that led to emergence of grasslands as major vegetation formations that now occupy some of the driest and hottest and the highest and coldest on earth as well as vast steppes and prairies in more temperate climes. It is the story of grasses successfully competing with forests and woodlands, aided and abetted by grazing herbivores and by humans and their use of fire as a tool. It is a story of adaptation to changing climates and the changing biophysical environments. A major focus of the book is the Palaearctic biogeographic realm that extends over some 45 million km2 and thus more than 1/3 of the terrestrial ice-free surface on Earth. It comprises extensive grasslands of different types and origin, which can be subdivided into (1) natural grasslands with (1a) steppes (climatogenic in dry climates), (1b) arctic-alpine grasslands (climatogenic in cold climates) and (1c) azonal and extrazonal grasslands (pedogenic and topogenic) as well as (2) secondary grasslands created and sustained by human activities, such as livestock grazing, mowing or burning. Grasslands of the Palaearctic do not only form a major basis for the agriculture of the region and thus its food supply, but are also crucial for other ecosystem services and host a supra proportional part of the realm’s plant and animal diversity. To reflect that suitability of grasslands for biodiversity strongly depends on their state, we apply the term High Nature Value grassland to those natural grasslands that are not degraded (in good state) and those secondary grasslands that are not intensified (semi-natural). The situation in a variety of countries where grasslands are evolving under the influence of global climate change is also considered. Case studies are presented on Southern Africa, Eastern Africa, India, China, South America, North America and Australia. The concluding chapter examines a set of themes arising from the chapters that make up the bulk of this book. The following provide a focus: recent history of grassland biomes – brief recap of current thinking and recent trends with special reference to dry grasslands in the Palearctic regions; the current status of grasslands and germplasm resources (biodiversity) – an overview; management systems that ensure sustainability; how to recover degraded grasslands; socio-economic issues and considerations in grassland management; the impacts of environmental problems in grasslands such as future climate change and intensification and the problems/prospects facing pastoralists and other grassland-based livestock producers.

Book Description
This report presents the case for why we all must throw our weight behind a global restoration effort. Drawing on the latest scientific evidence, it explains the crucial role played by ecosystems from forests and farmland to rivers and oceans, and charts the losses that result from our poor stewardship of the planet. While restoration science is a youthful discipline, we already have the knowledge and tools we need to halt degradation and restore ecosystems. Farmers, for instance, can draw on proven restorative practices such as sustainable farming and agroforestry. Landscape approaches that give all stakeholders - including women and minorities - a say in decision-making are simultaneously supporting social and economic development and ecosystem health. And policy makers and financial institutions are realizing the huge need and potential for green investment.

Book Description
This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.

Book Description
This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
