The occurrence of two severe droughts in north-east China since 2000 has
raised attention in the risk presented by droughts. This paper presents a
historic drought series for Shenyang in Liaoning Province, north-east China,
from 1200 CE to the present with a reconstructed long precipitation series
(1906–2015) augmented with historical documentary accounts. Analysis of the instrumental series using a standardized precipitation index (SPI) and
extending it using historical records has produced a combined series
spanning over 8 centuries. The combined long series was analysed for
patterns in drought frequency, severity and typology. Three droughts
comparable to those since 2000 occur in the instrumental series during the
early 20th century (i.e. 1907, 1916–1918 and 1920–1921), and coeval
archival sources reveal the human impacts of these severe droughts. The
archival sources demonstrate how reduced vulnerability resulting from
societal and cultural changes in the early 20th century helped prevent
the loss of life experienced during comparable severe droughts at the end of the 19th century (1887 and 1891). Incorporating a longer temporal
perspective to drought analysis shows that onset is often earlier than is
documented explicitly within the archives, and so combined SPI series for a
region could provide an early warning of drought development expressed as a
water deficit in the previous year. Analysis of archival data provides a
rich historical description of impacts and societal responses to severe
drought. The archives provide a rich historical description of drought
impacts and responses at the personal and community level whilst also
detailing the different roles played by communities, state and international organizations in responding to events.
