Long-term monitoring of aridization in agriculture before and after climate change in Ukraine

This paper presents the results of systematic monitoring in Ukraine for manifestations aridity according to method summarizing spring, summer, and autumn droughts conducted by I. Ye. Buchynskyi 1872-1969 authors' meteorological generalizations weather types (1951-1984) clearly expressed zonal climate changes (1985-2006) statistical local signs aridization at station northern part Forest Steppe (“Chabany”) – 2006-2020, covering a total 150 years historical time. According spatial distribution droughts, determined unified methodology, starting from 1872 ending late 1960s, defining indicator is gradual seasonal with recurrence spring after 2 years, summer 4 mainly south Ukraine, The number moderate large since beginning 20th century (11-30% area) are typical period, they repeated 4-5 years. Abnormal (over 50%) inherent areas every tenth year, which, last quarter 19th until 1950s, ended famine population (especially 1891, 1921, 1947). Subsequent 1963 1968 were abnormal conditions, but without manifestation food crisis, which associated chemicalization an increase agricultural culture. Meteorological indicators six stations diverse natural climatic zones 1951-1981 1985-2008 indicate positive air temperatures decrease precipitation, deficit compensated farming system saturation organic mineral fertilizers, have stabilizing effect extreme Since century, been identified that not only greenhouse effect, also periodicity depends on ecliptic globe. Climate recent decades particularly noticeable, accompanied temperature requires new technical technological solutions humanity
