DECODING. According to the last report from the intergovernmental panel on climate change (IPCC), Central Asia is one of the rarest regions in the world where both droughts and excessive rainfall in large quantities are observed. The average temperatures of these countries in the region have already crossed the 2 degrees Celsius threshold since 1990.<\/strong>However, there is no time for panic: Central Asia is already used to the harsh climate, where the temperature difference can sometimes differ as much as 80 degrees Celsius over the course of a year. Simultaneously, the researchers of IPCC are faced with a lack of more detailed data regarding Central Asia, which makes modelling difficult. How will the climate in Central Asia change? Novastan tries to make sense of it.<\/strong> This article was originally published on Novastan\u2019s French website<\/a> on September 13, 2021.<\/strong>\n\nIn recent years, the extreme climatic events in Central Asia are becoming more and more visible: more frequent heat waves<\/a>, flooding<\/a>, low rainfall<\/a>, etc. The region, like the rest of the world, is not immune to what appears to be an accelerating climate change. <\/a>\n\nOn 9 August, the intergovernmental panel on climate change<\/a> (IPCC) published<\/a> the first part of their report describing the state of the world\u2019s climate. The nearly 4000 pages report<\/a> focuses on the known physical change. Central Asia is squeezed between the two paragraphs, as an illustration of its position in today\u2019s information flows.\n<\/p>\n\n\n\n

Extreme Rainfall and Drought<\/strong><\/h4>\n\n\n\n

\u201c<\/em><\/strong>The vast regions of Central and Eastern Asia have been drying up at the start of the 2000s due to hotter temperatures, lower humidity, declining soil moisture (Wei and Wang, 2013: Li et al., 2017d; Hessl and coll.,2018)\u2019\u2019<\/em>, described the IPCC scientists.\n\n\u201cThe Himalayan glaciers supply ten of the most important river systems in the world and are critical water sources for almost two billion people (Wester et al., 2019). However, they are part of the most vulnerable \u201cwater towers\u201d (Immerzeel et al., 2020) which are expected to experience volume losses of around 30% to 100% by 2100, according to global emission scenarios (Marzeion et al., 2020). According to the global emission scenarios, the glaciers of this region should reach their maximum run-off between 2020 and 2040 (Marzeion et al., 2020)<\/em>\u201d<\/em>, went on the panel.\n\nRead more on Novastan: <\/strong>Aralsk: Pictures Of The Vanished Aral Sea<\/strong><\/a>\n\nOn a wider level, Central Asia is one of the few regions in the world which receives both the most extreme rainfall and experiences hot weather episodes, or even droughts<\/a>, describes the IPCC. According to Alisher Mirzabaev<\/a>, a researcher on climate change at the University of Bonn, this situation is due to the fact that the region is subject to a large variety of climates. \u201cMost of the cultivated land of Kazakhstan receives rainwater, while other countries irrigate their land mainly with water coming from the glaciers\u201d<\/em>, explains the Uzbek researcher, contacted by Novastan. This distinction between the origin of water appears essential for the years to come.\n<\/p>\n\n\n\n

A Change of the Origin of Water <\/strong><\/h4>\n\n\n\n

\u201cThe north of Kazakhstan generally experiences a drought every three to four years. With climate change, this area may experience heavy rains in certain years while in some other years there will be much greater droughts\u201d<\/em>, wrote Alisher Mirzabaev. \u201cThis situation leads to more variability for the grain harvests. In the mountainous regions, especially of Tajikistan and of Kyrgyzstan, strong rainfall episodes will lead to a higher risk of floods leading to a landslide\u201d<\/em>, explains the Uzbek specialist.\n\nRead more on Novastan: <\/strong>Life By The River: The Naryn In Kyrgyzstan<\/strong><\/a>\u201cTajikistan and Uzbekistan are likely to receive more precipitation during winter, but less in summer. It is problematic because there are neither crops in winter, nor irrigation. Water will accumulate in the reservoirs, which are fortunately numerous. However, the mountainous zones are going to face challenges due to more flooding\u201d,<\/em> estimated the researcher.\n\nWhat is most problematic is the shift in water supply, when the areas used to receive it through the snowmelt get it from the rain instead. This change may explain how Central Asia have both more rain and more drought, since the water received by the rain may not be accumulated in mountainous areas.\n\nHowever, this change does not seem to overly worry Alisher Mirzabaev. \u201cSolutions do exist, particularly <\/em>[the problem can be solved] by the construction of reservoirs or through better coordination between countries upstream and downstream. There is no need to panic at this stage, these solutions must simply be explored and implemented on a larger scale,\u2019\u2019<\/em> estimated the Uzbek researcher.\n<\/p>\n\n\n\n

A Sharp Rise in Temperature<\/strong><\/h4>\n\n\n\n

\nBeyond the water, one of the most evocative points of the report about Central Asia is the changing temperature of the region. \u201cAridity in eastern and western Central Asia is likely to increase, especially after the second half of the 21st<\/sup> century, with an average 2 degrees rise of temperatures worldwide\u201d<\/em>, describe the IPCC researchers. It is regularly reported that the temperature in Central Asia has already exceeded the 2\u00b0C increase and the region is warming twice as fast<\/a> as elsewhere in the world.\n\n<\/p>\n\n\n\t\t\t
