“…We conducted a composite analysis of atmospheric circulation differences in years with high and low burned area. Cherednichenko et al [69] suggested that the convective clouds supply most of the precipitation in the summer season for the central Kazakhstan during the summer season. We found that the large moisture flux from the Atlantic Ocean to the Central Kazakhstan and a weakened ridge over the WCKZ region can ascribe more precipitation [70] and is conducive to the development of convective precipitation ultimately causing lower burned areas in the region.…”

Central Asia is prone to wildfires, but the relationship between wildfires and climatic factors in this area is still not clear. In this study, the spatiotemporal variation in wildfire activities across Central Asia during 1997–2016 in terms of the burned area (BA) was investigated with Global Fire Emission Database version 4s (GFED4s). The relationship between BA and climatic factors in the region was also analyzed. The results reveal that more than 90% of the BA across Central Asia is located in Kazakhstan. The peak BA occurs from June to September, and remarkable interannual variation in wildfire activities occurs in western central Kazakhstan (WCKZ). At the interannual scale, the BA is negatively correlated with precipitation (correlation coefficient r = −0.66), soil moisture (r = −0.68), and relative humidity (r = −0.65), while it is positively correlated with the frequency of hot days (r = 0.37) during the burning season (from June to September). Composite analysis suggests that the years in which the BA is higher are generally associated with positive geopotential height anomalies at 500 hPa over the WCKZ region, which lead to the strengthening of the downdraft at 500 hPa and the weakening of westerlies at 850 hPa over the region. The weakened westerlies suppress the transport of water vapor from the Atlantic Ocean to the WCKZ region, resulting in decreased precipitation, soil moisture, and relative humidity in the lower atmosphere over the WCKZ region; these conditions promote an increase in BA throughout the region. Moreover, the westerly circulation index is positively correlated (r = 0.53) with precipitation anomalies and negatively correlated (r = −0.37) with BA anomalies in the WCKZ region during the burning season, which further underscores that wildfires associated with atmospheric circulation systems are becoming an increasingly important component of the relationship between climate and wildfire.

“…Most of the lakes, including Lake Balkhash, the Republic's largest water body, are nevertheless shallow, lack outlets, and because of the climate, subject to abrupt changes in water Most of Kazakhstan's rivers originate in mountainous areas and are charged by seasonal snowmelt [25,27]. Spring floods are common, and drought periods routinely cause smaller streams to dry up as they flow across the arid lowlands [28,29]. The continental climate of Kazakhstan conditions sporadic drought in the summer and autumn [27,30], and this results in low water availability in some years and adequate or even excess water in others [31,32].…”

Kazakhstan, a former Soviet republic that is now independent, lies near the center of arid Eurasia. Its sparse hydrographic network includes a small number of large rivers, lakes, and reservoirs, many ponds and smaller streams, as well as littoral zones bordering the Caspian Sea and the Aral Sea. A diverse fisheries sector, initially based on wild fish capture and later including aquaculture, developed in these waters during the Soviet era, when animal agriculture was unable to meet the protein needs of Soviet citizens. The sector, which was originally centered on the Volga–Caspian basin, was tightly managed by Moscow and benefitted from coordinated investments in research, infrastructure, and human resources, as well as policies to increase the consumption of fish products. Independence in 1991 administered a political and economic shock that disrupted these relationships. Kazakhstan’s wild fish harvests plummeted by more than two-thirds, and aquaculture collapsed to just 3% of its previous level. Per capita consumption of fish products also declined, as did processing capacity. Favorable recent policies to define fishing rights, incentivize investments, prevent illegal fishing, and make stocking more effective have helped to reverse these trends and stabilize the sector. Continued recovery will require additional steps to manage water resources sustainably, prioritize the use of water for fish habitats, and minimize the effects of climate change. This comprehensive assessment of Kazakhstan’s fisheries sector over the past century provides the basis to understand how long-term dynamic interactions of the environment with the political economy influence fisheries in Eurasia’s largest country.

“…The Republic of Kazakhstan is located in Central Asia between 39°49′ -55°49′ N and 46°28′-87°18′ E, with its western part extending into Eastern Europe. Kazakhstan is the ninth largest country in the world with a total area of 2,727,300 km², also ranking as the world's largest landlocked country [1,2]. It borders Russia, Kyrgyzstan, Turkmenistan, Uzbekistan and China [3].…”

Background The Republic of Kazakhstan, located in Central Asia, ranks as the world’s largest landlocked country, and borders five countries including China. There is a 1783 km long borderline between the South and East regions of Kazakhstan and Xinjiang Uygur Autonomous Region (XUAR, northwestern China). To date, there is no report on the genetic diversity of ticks in these regions. Methods During 2015–2019, a total of 4392 hard ticks (representatives of ten species) were collected from 605 animals (sheep, cattle, camels, dogs and hedgehogs) at 24 sampling sites belonging to 15 districts in southeastern Kazakhstan. After morphological identification, 213 specimens of these ticks were selected for molecular analyses. In addition, 157 hard ticks collected from sheep and camels between 2015 and 2018 in seven districts of XUAR were used for comparison. Following DNA extraction, a fragment of the mitochondrial cytochrome c oxidase subunit I (cox1) gene, ranging from 631 bp to 889 bp, was used to analyze genetic diversity among these ticks. Findings: Phylogenetic analyses indicated that i) five tick species including Hyalomma detritum, Hyalomma asiaticum, Rhipicephalus turanicus, Dermacentor reticulatus and Haemaphysalis erinacei from Kazakhstan clustered together with conspecific ticks from XUAR; ii) the phylogenetic separation of Dermacentor marginatus from Kazakhstan and XUAR was highly supported; and iii) Rhipicephalus sanguineus sensu lato from Alamaty Oblast was more closely related to a specimen from Iran than to that from XUAR. The network diagram of haplotypes showed that iv) Hy. asiaticum from Almaty and Kyzylorda (Kazakhstan) together with that from Yuli County of XUAR constituted an ancestral haplogroup; and v) three lineages of Rh. turanicus (from Israel, Almaty and South Kazakhstan, as well as from Usu city, Ulugqat and Baicheng Counties of XUAR) might have originated from an ancestral lineage in Alataw city, XUAR. Conclusions These findings indicate that: (i) mitochondrial lineages of some tick species are shared between southern, eastern regions of Kazakhstan and northwestern China; (ii) common evolutionary origin of Hy. asiaticum and Rh. turanicus in these regions might be attributed to historical international trade and movements of wildlife; and (iii) certain tick species show clear differences between Kazakhstan and XUAR, either in terms of abundance (e.g. Hy. scupense, Hy. marginatum) or exhibiting a phylogenetic split between these regions (relevant to D. marginatus).
