Описание: 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.

Описание: This bookprovides an in-depth analysis of the wheat production developments in theEurasian region and assesses the potential contribution of the region todomestic and international food security. In particular, the book covers policyand institutional developments of the agricultural sector in Eurasia with aspecial focus on the horizontal issues relevant to the current and futurepotential growth of the wheat production, such as land policy, credit andfinance, privatization, farm restructuring, and environmental challenges.Global foodsecurity is a major societal concern in the light of an increasing population,which is projected to grow from around seven billion today to almost 10 billion in2050. Two most likely ways to achieve the much needed food production growthare: expansion of land cultivation or increase in crop yields and total factorproductivity. The only region with a significant amount of uncultivated arableland that is at the same time experiencing rising agricultural productivity isthe “Eurasian wheat belt,” comprising of Russia, Ukraine, Kazakhstan, and theCentral Asian countries (Uzbekistan, Tajikistan, Turkmenistan, and Kirgizstan).This makes the region a potential hotspot for driving the future growth ofglobal agriculture. Such prospects require a detailed investigation ofEurasia’s future perspectives in terms of food production (with a focus onwheat) and its potential contribution to regional and global food security.
