“…High-intensity, irrigated agriculture is more dominant in Uzbekistan (0.42 million km 2 ) than in Kazakhstan (0.21 million km 2 ) (Kienzler et al 2012). Highly intensive agriculture is usually associated with a higher research input than lowintensity agriculture.…”

“…In addition, the Central Asian office of the International Water Management Institute (IWMI) in Tashkent has been very active since the beginning of 2000 in promoting research activities in three countries of the Ferghana Valley (namely, Kyrgyzstan, Tajikistan, and Uzbekistan) to implement an integrated water resource management approach. Turkmenistan also has a considerable share of irrigated cropland with 0.18 million km 2 (Kienzler et al 2012), but there are few research papers relevant to this country (Fig. 5).…”

Agriculture is major sector in the economy of Central Asia. The sustainable use of agricultural land is therefore essential to economic growth, human well-being, social equity, and ecosystem services. However, salinization, erosion, and desertification cause severe land degradation which, in turn, degrade human health and ecosystem services. Here, we review the impact of agricultural land use in the five countries of Central Asia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, during 2008-2013 in 362 articles. We use the Land Use Functions framework to analyze the type and relative shares of environmental, economic, and social topics related to agricultural land use. Our major findings are (1) research on land use in Central Asia received high levels of international attention and the trend in the number of publications exceeded the global average. (2) The impacts of land use on abiotic environmental resources were the most explored. (3) Little research is available about how agricultural land use affects biotic resources. (4) Relationships between land degradation, e.g., salinization and dust storms, and human health were the least explored. (5) The literature is dominated by indirect methods of data analysis, such as remote sensing and mathematical modeling, and in situ data collection makes up only a small proportion.

“…The increased water consumption resulting from irrigation will potentially limit the water supply to other sectors as well as the amount of available water for downstream areas. Such changes in water resource allocation will have significant impacts on the long-term sustainability of the socio-ecological systems in the middle and lower reaches of the Heihe River, as water-related environmental degradation problems have been observed in this region (Qi and Luo 2007), including natural vegetation dieback of up to 80 % and surface runoff decreases of up to approximately 30 % ), groundwater depletion (Wei et al 2007), desertification, secondary salinization incurred by over-irrigation (Ma et al 2013), and agricultural non-point source water pollution (Nan et al 2010), which were also widely observed in other dryland areas such as those existing in Australia and Argentina (Beverly et al 2011;Jayawickreme et al 2011;Kienzler et al 2012).…”

Land use and ecosystem services need to be assessed simultaneously to better understand the relevant factors in sustainable land management. This paper analyzed land use changes in the middle reach of the arid Heihe River Basin in northwest China over the last two decades and their impacts on water resources and soil organic carbon (SOC) storage. The results indicated that from 1986 to 2007: (1) cropland and human settlements expanded by 45.0 and 17.6 %, respectively, at the expense of 70.1, 35.7, and 4.1 % shrinkage on woodland, grassland, and semi-shrubby desert; (2) irrigation water use was dominant and increased (with fluctuations) at an average rate of 8.2 %, while basic human water consumption increased monotonically over a longer period from 1981 to 2011 at a rate of 58 %; and (3) cropland expansion or continuous cultivation led to a significant reduction of SOC, while the land use transition from grassland to semishrubby desert and the progressive succession of natural ecosystems such as semi-shrubby desert and grassland, in contrast, can bring about significant carbon sequestration benefits. The increased water consumption and decreased SOC pool associated with some observed land use changes may induce and aggravate potential ecological risks for both local and downstream ecosystems, including water resource shortages, soil quality declines, and degeneration of natural vegetation. Therefore, it is necessary to balance socioeconomic wellbeing and ecosystem services in land use planning and management for the sustainability of socio-ecological systems across spatiotemporal scales, especially in resource-poor arid environments.

“…An alternative option would be government-financed soft loan programs to farmers targeting the adoption of new resource-efficient and climate smart technologies. The large scale adoption of conservation tillage practices in Kazakhstan on several millions of hectares was partially found to be facilitated by government subsidies promoting this technology (Kienzler et al 2012). However, limited public funds may serve as barriers for other such programs at a larger scale, especially in the poorer parts of the region.…”

Improving the Resilience of Central Asian Agriculture to Weather Variability and Climate Change

Central Asia is projected to experience significant climate change, combined with increased weather volatility. Agriculture is a key economic sector and a major source of livelihoods for Central Asia's predominantly rural population, especially for the poor. Agricultural production, being sensitive to weather shocks and climate volatility, may be negatively affected by climate change if no adaptive actions are taken. Climate smart technologies could help in strengthening the resilience of agricultural producers in the region to increased weather variability due to climate change. This study identifies the key barriers and opportunities for a wider adoption of climate smart technologies and also evaluates their potential impacts on agricultural revenues of differentiated groups of agricultural producers, with a focus on the poor. Adoption of climate smart agricultural technologies was found to raise farming profits of both poorer and richer households, although these positive impacts may likely to be higher for richer households. The study also shows that policies facilitating improved access to markets and agricultural extension services, as well as higher commercialization of household agricultural output may increase the adoption of climate smart agricultural technologies in the region.
