Book Description
Steppes—semi-arid biomes dominated by forbs, grasses, and grass-like species, and characterized by extremes of cold and heat—occupy enormous areas on four continents. Yet these ecosystems are among the least studied on our planet. Given that the birth and evolution of human beings have been so intimately interwoven with steppe regions, it is amazing that so few attempts have been made to compare and quantify the features of these regions. In this ground-breaking volume, five leading voices in horticulture—all staff members of Denver Botanic Gardens—examine the plants, climate, geology, and geography of the world’s steppes: central Asia, central and intermountain North America, Patagonia, and South Africa. Drawing upon their first-hand experience, the writers illuminate the distinctive features of each region, with a particular emphasis on the striking similarities between their floras. Each chapter includes a primer of species of horticultural interest—a rich resource for readers with an interest in steppe plants.

Book Description
This is the first comprehensive survey of all the deserts of Arabia, based largely on the author’s 50 years of experience there. The text deals with every kind of desert in the region, from vast sand seas to clay pans and stony plains to volcanic flows. Along with dune types unique to the region the author outlines climatic changes, current ecology and human influence on desertification.

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
The book describes richness and diversity of Georgia’s vegetation. Contrasting ecosystems coexist on the relatively small territory of the country and include semi-deserts in East Georgia, Colchic forests with almost sub-tropical climate in West Georgia and subnival plant communities in high mountains. West Georgia lacks xerophilous vegetation zone and mesophilous forest vegetation spreads from the sea level to subalpine zone. The Colchic refugium (West Georgia) ensured survival of the Tertiary’s mesophilous forest flora. Vertical profile of the vegetation is more complex in East Georgia with semi-desert, steppe and arid open forest zone. In South Georgia the montane zone represented by montane steppe is devoid of forests

Book Description
Halophytes for Food Security in Dry Lands addresses the concerns surrounding global food scarcity, especially focusing on those living in arid and dry lands The book touches on food crises in dry regions of the world and proposes halophytes as an alternate source of consumption for such areas. Halophytes, those plants that thrive in saline soil and provide either food source options themselves, or positively enhance an eco-system's ability to produce food, and are thus an important and increasingly recognized option for addressing the needs of the nearly 1/6 of the world's population that lives in these arid and semi-arid climates. Including presentations from the 2014 International Conference on Halophytes for Food Security in Dry Lands, this book features insights from the leading researchers in the subject. It is a valuable resource that includes information on the nutritional value of halophytes, their genetic basis and potential enhancement, adaption of halophytes, and lessons learned thus far. - Provides comprehensive coverage of the importance and utilization of halophytes to compensate the demand of food in whole world especially in the dry regions - Contains insights from ecological to molecular fields - Includes edible halophytes as well as those that enhance food-producing eco-systems - Presents information for improving abiotic stress tolerance in plants

Book Description
Environmental conditions do not exist in a vacuum. They are influenced by science, politics, history, public policy, culture, economics, public attitudes, and competing priorities, as well as past human decisions. In the case of Central Asia, such Soviet-era decisions include irrigation systems and physical infrastructure that are now crumbling, mine tailings that leach pollutants into soil and groundwater, and abandoned factories that are physically decrepit and contaminated with toxic chemicals. Environmental Crises in Central Asia highlights major environmental challenges confronting the region’s former Soviet republics: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. They include threats to the Caspian and Aral seas, the impact of climate change on glaciers, desertification, deforestation, destruction of habitat and biodiversity, radioactive and hazardous wastes, water quality and supply, energy exploration and development, pesticides and food security, and environmental health. The ramifications of these challenges cross national borders and may affect economic, political, and cultural relationships on a vast geographic scale. At the same time, the region’s five governments have demonstrated little resolve to address these complex challenges. This book is a valuable multi-disciplinary resource for academics, scholars, and policymakers in environmental sciences, geography, political science, natural resources, mass communications, public health, and economics.
