Book Description
Known as the “roof of the world,” the Tibetan Plateau is the highest and largest plateau on Earth. Tibetan Plateau hosts several mountain ecosystems characterized by high elevations, cold conditions, and a wide range in water availability. Its unique physical and geographical environment includes ecosystems typical for alpine regions, classified as alpine grasslands, which account for 50-70% of the total land area of the Tibetan plateau. Most of these grasslands contain fragile tundra-like environments which are seriously affected by anthropogenic modifications and whose restoration presents a challenge. These natural grassland types include alpine deserts, alpine steppes, alpine meadows, and alpine swamp meadows along precipitation gradients, as well as the transition types between them. Alpine grasslands remain subject to severe degradation by multiple factors, mainly overgrazing and climate warming. As a result, grasslands exhibit a decreased capacity to support biodiversity and complexity, and more generally, ecosystem functions. Therefore, these changes also affect social and recreational activities and restrict access to clean water and food by local communities.

Book Description
The grassland ecosystem on the global alpine area has been degraded seriously over the past half century. It can be compared to the Dust-Bowlification, that is, the degradation of American grasslands over the last century. This book was compiled by outstanding researchers who have been engaged in field research on the global alpine area for over 20 years, with the aim of describing the degradation and restoration of grassland on the global alpine area. The long-term field studies and personal experience of the authors describe the process of grassland degradation and the difficulties in the restoration efforts. Grassland degradation and restoration on the global alpine area involves the stripping and regeneration of the grassland's mattic epipedon. The stripping of the mattic epipedon is a unique phenomenon on the global alpine area, which has left many unanswered questions. Is stripping degradation an inherent, inevitable feature of the alpine grassland ecosystem? Is it an avoidable occurrence? Why is ecological restoration of stripped degraded grassland extremely difficult? Does restoration rely on reconstructing the grassland's mattic epipedon? Or can it be done in another way? How can sustainable ecological restoration be achieved? Frontline researchers in global alpine area have used observational evidence from field studies to respond to these questions and to present a comprehensive picture of the problems and drivers of grassland degradation. The climate-environment interaction mechanism of grassland degradation is revealed by the holistic approach in this book. Ecological restoration is discussed through social and economic participation, and past and present restoration actions are analyzed from the perspective of traditional culture and ecological ethics. The future sustainable management of grassland under climate change and social and economic development trend is discussed. This book will alert people to the dangers of degradation and to the difficulties encountered in ecological restoration. - Thoroughly presents the processes of grassland degradation from the novel viewpoint of the stripping of mattic epipedon - Features the most recent studies to provide new research evidence for long-term grassland restoration efforts on the global alpine area - Contains in-depth analysis of the processes, mechanisms, and drivers of grassland degradation. - Discusses the restoration of degraded grasslands using restoration theory and technologies

Book Description
This book contains 28 chapters with emphasis on the interactive nature of the relationships between the soil, plant, animal and environmental components of grassland systems, both natural and managed. It analyses the present knowledge and the future trends of research for combining the classical view of grasslands, as a resource for secure feeding of an increasing human population, with the more recent perspective of the contribution of grasslands to the mitigation of environmental impacts and biodiversity erosion as consequences of human society activities. The chapters are organized within five sections dealing with the different functions and the main ecosystem services expected from grasslands: (i) domestic herbivore feeding and animal production; (ii) the regulation of biogeochemical cycles and its consequences for the environment; (iii) dynamics of biodiversity hosted by grasslands; (iv) integration of grasslands within sustainable animal production systems; and (v) interactions of grassland areas with other land use systems at the landscape level.

Book Description
Pilot Analysis of Global Ecosystems (PAGE): Coastal Ecosystems analyzes quantitative and qualitative information and develops selected indicators of the condition of the world's coastal ecosystems and marine fisheries. Specifically the study looks at measures that show the degree of human modification of coastal zone and what we know concerning five important goods and services provided by coastal ecosystems: filtering water, food, biodiversity, shoreline stabilization, and tourism. Results from the PAGE analysis show that human activities have extensively altered coastal ecosystems worldwide. Nearly 30 percent of the land area in the world's coastal ecosystems had already been extensively altered or destroyed by growing demand for housing, industry, and recreation. Globally, the number of people living within 100 km of the coast increased from roughly 2 billion in 1990 to 2.2 billion in 1995 four out of every ten people in the world. As coastal and inland populations continue to grow, their impacts in terms of pollutant loads and the development and conversion of coastal habitats can be expected to grow as well. Nutrient pollution has increased dramatically this century due to greater use of fertilizers, growth in quantities of domestic and industrial sewage, and increased aquaculture, which releases considerable amounts of waste directly into the water. Increasing fishing pressure have left many major fish stocks depleted or in decline. Global climate change may compound other pressures on coastal ecosystems through the additional effects of warmer ocean temperatures, altered ocean circulation patterns, changing storm frequency, and rising sea levels.

Book Description
The years 2021 to 2030 have been designated as "The United Nations Decade on Ecosystem Restoration". Ecological restoration and biodiversity conservation efforts face unprecedented challenges, especially in developing countries and areas, such as the Hindu Kush-Himalayan (HKH) region. This huge HKH region, which includes areas in eight separate countries (Afghanistan, Pakistan, Nepal, India, China, Bangladesh, Myanmar and Bhutan), is a biodiversity hotspot with a vast array of ecosystems, landscapes, peoples and cultures. It is known as one of 'the pulses of the world'. However, the HKH is also the world's largest and poorest mountain region, where landscapes and environments have been severely damaged as a result of climate change and human activities. Coordinating conservation and restoration policies, sharing knowledge and funds, and maintaining livelihoods are major challenges and are in urgent need of improvement. This book details the past and current ecological problems in the HKH region, and the threats and challenges that ecosystems and local people face. It pays special attention to developments of transformative adaptations and presents examples of sustainable conservation and ecological restoration management practices. This book is essential reading for ecologists and conservation biologists involved in large-scale ecological restoration projects, along with practitioners, graduate students, policy makers and international development workers.
