This paper quantitatively analyzed the evolution of human–water
relationships in the Heihe River basin of northern China over the past 2000
years by reconstructing the catchment water balance by partitioning
precipitation into evapotranspiration and runoff. The results provided the
basis for investigating the impacts of societies on hydrological systems.
Based on transition theory and the rates of changes of the population, human
water consumption and the area of natural oases, the evolution of
human–water relationships can be divided into four stages: predevelopment
(206 BC–AD 1368), take-off (AD 1368–1949), acceleration
(AD 1949–2000), and the start of a rebalancing between human and ecological
needs (post AD 2000). Our analysis of the evolutionary process revealed that
there were large differences in the rate and scale of changes and the period
over which they occurred. The transition of the human–water relationship had
no fixed pattern. This understanding of the dynamics of the human–water
relationship will assist policy makers in identifying management practices
that require improvement by understanding how today's problems were created
in the past, which may lead to more sustainable catchment management in the
future. |
