Zusammenfassung |
It is increasingly acknowledged that, in order to sustainably manage global
freshwater resources, it is critical that we better understand the nature of
human–hydrology interactions at the broader catchment system scale. Yet to
date, a generic conceptual framework for building models of catchment
systems that include adequate representation of socioeconomic systems – and
the dynamic feedbacks between human and natural systems – has remained
elusive. In an attempt to work towards such a model, this paper outlines a
generic framework for models of socio-hydrology applicable to agricultural
catchments, made up of six key components that combine to form the coupled
system dynamics: namely, catchment hydrology, population, economics,
environment, socioeconomic sensitivity and collective response. The
conceptual framework posits two novel constructs: (i) a composite
socioeconomic driving variable, termed the Community Sensitivity state
variable, which seeks to capture the perceived level of threat to a
community's quality of life, and acts as a key link tying together one of
the fundamental feedback loops of the coupled system, and (ii) a Behavioural
Response variable as the observable feedback mechanism, which reflects land
and water management decisions relevant to the hydrological context. The
framework makes a further contribution through the introduction of three
macro-scale parameters that enable it to normalise for differences in
climate, socioeconomic and political gradients across study sites. In this
way, the framework provides for both macro-scale contextual parameters,
which allow for comparative studies to be undertaken, and catchment-specific
conditions, by way of tailored "closure relationships", in order to ensure
that site-specific and application-specific contexts of socio-hydrologic
problems can be accommodated. To demonstrate how such a framework would be
applied, two socio-hydrological case studies, taken from the Australian
experience, are presented and the parameterisation approach that would be
taken in each case is discussed. Preliminary findings in the case studies
lend support to the conceptual theories outlined in the framework. It is
envisioned that the application of this framework across study sites and
gradients will aid in developing our understanding of the fundamental
interactions and feedbacks in such complex human–hydrology systems, and
allow hydrologists to improve social–ecological systems modelling through
better representation of human feedbacks on hydrological processes. |
