Under the influence of anthropogenic and natural factors, a further increase in agricultural drought is expected in the south of Central Asia in the 21st century, according to Chinese researchers, reports Ritmeurasia.ru.

In the late spring and early summer of 2021, a severe drought prevailed in many areas of Central Asia, which caused damage to local agriculture and pastoralism. According to training comparisons, similar extreme weather events have occurred frequently in this region over the past 30 years. This is what aroused the interest of scientists in studying the causes of prolonged soil drought and forecasting the prospects for the development of the situation.

Periodic droughts in Central Asia have been linked to anthropogenic factors and climate variability, with the Interdecadal Pacific Oscillation (IPO) playing a major role. It periodically intensifies and weakens every 20-30 years, the researchers concluded.

Under the influence of the ITC is the water regime of soils in the south of Central Asia. Since the 1990s, the ITC cycle has led to a reduction in precipitation in the region, which complicates the problem of drought here.

Chinese scientists believe that even if in the next few decades the ITC begins to move to a warm phase, favorable for an increase in precipitation, it will still be difficult to withstand the intensifying drought in Central Asia.
