With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

This book presents a portrait of the social advantages and limitations of climate change related modeling in the Hindu Kush-Himalayan (HKH) region. It addresses the implied but largely uncritiqued relationships between scientific modeling knowledge and local adaptation responses. It also presents theoretical perspectives on modeling and adaptation,

The grazing of animals on common land and associated property rights were the original basis of the concept of "the tragedy of the commons". Drawing on the classic work of Elinor Ostrom and the readings of political ecology, this book questions the application of exclusive property rights to mobile pastoralism and rangeland resource governance. It argues that this approach inadequately represents property relations in the context of Mongolian pastoralism. The author presents an in-depth exploration and analysis of mobile pastoral production and resource management in Mongolia. The country is widely considered to be a prime example of successful and resilient common pool resource management, but now faces a dilemma as policy advocates attempt to adjust historical pastoralism to a modern property regime framework. The book strengthens understanding of the complex and multilateral considerations involved in natural resource governance and management in a mobile pastoralist context. It considers the implications for common pool resource management and pastoral societies in Africa, Russia and China and includes recommendations for formulating national policy.

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.

Fascinating and diverse, savanna ecosystems support a combination of pastoral and agropastoral communities alongside wild and domestic herbivores that can be found nowhere else. This diversity has made the study of these areas problematic. Ecosystem Function in Savannas: Measurement and Modeling at Landscape to Global Scales addresses some of the d
