Book Description
Steppe environments impose strong selection pressures on organisms due to limiting climate conditions. Biotic factors also exert important pressures on steppe organisms, which display notable and interesting adaptations. At the same time, steppes are among the most fragile and human-impacted ecosystems of the world. As a result of these ecological and conservation features, steppe ecosystems and organisms have long deserved the attention of ecologists, biogeographers and conservation biologists. Through the contribution of steppe ecology experts from different regions of the world, this volume aims to answer hot questions in steppe ecology and conservation such as how did present-day steppe ecosystems arise? Is the steppe a perfectly identifiable and homogeneous biome, or are there different types of steppes? If the latter is true, what are the abiotic and biotic factors that define steppe ecosystems? Do they function differently? In short, what is a steppe? Can we identify clearly steppe-specific taxa? Are their functional traits homogeneous across steppe ecosystems? How are their main biodiversity patterns?However, this book also responds to the current concern about the future of the worlds steppes, threatened by increasing land-use intensification, which brings out the need for their sustainable management on the basis of adequate scientific knowledge. Therefore, the chapters comprising this book not only diffuse current scientific knowledge on steppe ecosystems, which is not a minor aim, but provide cues and tools to evaluate their state and to scientifically inform and help their management. Let us hope these messages reach the adequate ears.

Book Description
Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.

Book Description
In the project, diverse educational programs are implemented for different target groups, including teachers, students, experts and decision makers responsible for the management of protected areas. An educational program was designed for students, including wall painting and drama activities with the artists, poetry and drawing competitions among schools, and a kite festival with the artists. Additionally, nature corners displaying the features of steppes were established in certain schools. As part of the education and awareness-raising program, an educational kit was prepared for teachers and students. This kit is a source document for increasing the knowledge, interest and awareness of children about the steppe ecosystems of ?anl?urfa. With this reference kit, you will be able to explore the diversity and importance of steppes from different perspectives such as history, biology, geography, sustainability, and climate change.

Book Description
This book provides a comprehensive overview of grassland ecosystems based on publications by Chinese scholars. It offers an up-to-date review of the recent advances in grassland research in China, discusses the climatic and physical conditions governing the grasslands, describes their types and distribution, and introduces a new classification scheme for grassland ecosystems. Further, it details the plant, animal, and microbial compositions of each grassland ecosystem type, examining the above and below ground relationships between phytomass, vegetation succession, and past/current management practices with a particular focus on the steppes in China. It also includes references that are only available in the Chinese language. This scientifically rigorous book offers insights into knowledge gaps for the scientific community and identifies pressing issues facing practitioners of grassland ecology and management. It can be used as a textbook for undergraduate and graduate students in ecology, environmental science, natural resource management, agriculture, and other relevant fields, and is also a valuable reference resource for researchers studying drylands in China or around the globe.

Book Description
The project is carried out collaboratively by the Food and Agriculture Organization of the United Nations (FAO) and the Ministry of Agriculture and Forestry General Directorate of Nature Conservation and National Parks (GDNCNP), General Directorate of Plant Production (GDPP), and General Directorate of Forestry (GDF) with the financial support of the Global Environment Facility (GEF). This project along with the National Steppe Conservation Strategy shows the importance FAO and the Ministry of Agriculture and Forestry attach to the conservation of Turkey’s rich and vulnerable steppe ecosystems, their sustainable and cooperative management and awareness-raising. This Strategy is instrumental in contributing to the conservation of unique steppe assets possessed by Turkey at national level as well as fulfillment of international commitments such as those arising from the International Convention on Biological Diversity, Aichi Goals of Convention on Biological Diversity and Convention to Combat Desertification. It appears that there are hardly any policies or legal documents directly geared towards steppe ecosystems in Turkey, as opposed to the legal and administrative documents for the conservation and management of mountain-forests, wetlands, and coastal and marine ecosystems. Therefore, the National Steppe Conservation Strategy and Action Plan assumes special importance.

Book Description
Modern Biogeochemistry is aimed to generalize modern ideas of biogeochemical developments during the last decades. It is designed to support a general course in biogeochemistry, and as such, is likely to have a broad market among the many universities and colleges that are adding such courses to their curricula. This book aims to supplement the existing textbooks by providing modern understanding of biogeochemistry, from evolutionary biogeochemistry to practical applications of biogeochemical ideas such as human biogeochemistry, biogeochemical standards and biogeochemical technologies. To a certain extent this textbook is a summary of both scientific results of various authors and classes in biogeochemistry, that have been given to students by authors during the last 5 to 10 years at different universities throughout the world such as Cornell, Moscow, Seoul and Bangkok. Biogeochemistry is becoming an increasingly popular subject for graduate and postgraduate education. Courses in ecology, geography, biology, chemistry, environmental science, public health and environmental engineering all tend to have a biogeochemical component in their syllabuses to a greater or lesser extent.

Book Description
This book is aimed at generalizing the modern ideas of both biogeochemical and environmental risk assessment that have been developed in recent years. Only a few books are available in this interdisciplinary area, since most deal mainly with various technical aspects of ERA description and calculations. This text aims at supplementing the existing books by providing a modern understanding of mechanisms responsible for ecological risks for human beings and ecosystems.

Book Description
On the eve of the World Summit for Sustainable Development (WSSD), held in autumn 2002 in Johannesburg, South Africa, United Nations Secretary General Kofi Annan recommended five specific areas as focal points of discussion for the global forum: Water, energy, health, agriculture and biodiversity. In his address, "Towards a Sustainable Future," delivered just four months before the WSSD, Secretary General Annan contended that concrete progress in each of these areas, often referred to by their acronym WEHAB, would be key to improving the quality of life not only in the developing world but across the globe. For most people, I think it is fair to say that the inclusion of biodiversity in a list that focuses on basic human needs may not be self-evident. Water, energy, health and agriculture, yes. But why biodiversity? The truth is that biodiversity is just as critical to global well-being as water, energy, agriculture and health. This is because biodiversity both drives and shapes nature's intricate and dynamic structure in an enduring form and force that enables both current and future generations to enjoy its bounty.
