| Rebalancing water allocation between human consumptive uses and the
environment in water catchments is a global challenge. This paper proposes a
socio-hydrological water balance framework by partitioning catchment total
evapotranspiration (ET) into ET for society and ET for natural ecological
systems, and establishing the linkage between the changes of water balance
and its social drivers and resulting environmental consequences in the
Murray–Darling Basin (MDB), Australia, over the period 1900–2010. The
results show that the 100-year period of water management in the MDB could be
divided into four periods corresponding to major changes in basin management
within the socio-hydrological water balance framework: period 1 (1900–1956)
– expansion of water and land use for the societal system, period 2
(1956–1978) – maximization of water and land use for the societal system,
period 3 (1978–2002) – maximization of water use for the societal system
from water diversion, and period 4 (2002–present) –
rebalancing of
water and land use between the societal and ecological systems. Most of
management changes in the MDB were passive and responsive. A precautionary
approach to water allocation between the societal and ecological systems
should be developed. The socio-hydrological water balance framework could
serve as a theoretical foundation for water allocation to evaluate the
dynamic balance between the societal and ecological systems in catchments. |
