    As the “new rangeland paradigm” took shape in the 1990s, climatic variability in pastoral ecosystems was often discussed as “uncertainty”, and the essential mobility of pastoral systems was argued to be possible only with flexible land access rights. These context-specific principles have increasingly been globalized in analyses of diverse pastoral systems.

    This paper examines the impact of land reform on agricultural productivity in Tajikistan. Recent legislation allows farmers to obtain access to heritable land shares for private use, but reform has been geographically uneven. The break-up of state farms has occurred in some areas where agriculture has little to offer but, where high value crops are grown, land reform has hardly begun. In cases where collectivized farming persists and land has not been distributed, productivity remains low and individual households benefit little from farming.

    Food security and the functioning of wheat markets in Eurasia

    Asie central, Tadjikistan

    We investigated wheat price relationships between the import-dependent countries in Central Asia and the South Caucasus and the Black Sea wheat exporters to assess wheat market efficiency. This is crucial for ensuring availability and access to wheat and for reducing food insecurity. Results from linear and threshold error correction models suggested a strong influence of trade costs on market integration in Central Asia, while those costs were of minor importance in the South Caucasus.

    It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

    Land degradation is a major challenge for agricultural and rural development
    in Uzbekistan. Our research findings indicate that the costs of land
    degradation in Uzbekistan are substantial; reaching about 0.85 billion USD annually
    resulting from the loss of valuable land ecosystem services due to land use and
    land cover changes alone between 2001 and 2009. On the other hand, economic
    simulations also show that the returns from actions to address land degradation can
    be four times higher their costs over a 30-year planning horizon, i.e. every dollar

    Land degradation affects negatively the livelihoods and food security of
    global population. There have been recurring efforts by the international community
    to identify the global extent and severity of land degradation. Using the long-term
    trend of biomass productivity as a proxy of land degradation at global scale, we
    identify the degradation hotspots in the world across major land cover types. We
    correct factors confounding the relationship between the remotely sensed vegetation

    In 2005 the Uzbek government accelerated the dissolution process of collective farms through full-scale land reform. As the central production unit, the collective enterprise was supplanted by a private, family-based enterprise. Simultaneously Water Users Associations (WUAs) were established that operate and maintain the irrigation and drainage infrastructure of the former collective farms. Though these land-cum-water reforms could in principle initiate enormous changes, there is still a strong continuity due to the state-regulated agricultural system.

    The Central Asian countries are particularly affected by the global climate change. The cultural and economic centers in this mostly arid region have to rely solely on the water resources provided by the rapidly melting glaciers in the Pamir, Tien-Shan and Alay mountains. By 2030, the available water resources will be 30 % lower than today while the water demand will increase by 30 %. The unsustainable land and water use leads to a water deficit and a deterioration of the water quality.

    Sigificant dependence from climate and anthropogenic influences characterize ecological systems of Kazakhstan. As result of the geographical location of the republic and ecological situation vegetative degradation sites exist throughout the territory of Kazakhstan. The major process of desertification takes place in the arid and semi-arid areas. To allocate spots of stable degradation of vegetation, the transition zone was first identified. Productivity of vegetation in transfer zone is slightly dependent on climate conditions.
