Evolution of Catchment Hydrology-Society-Ecology System (ECHS) II Posters

Submit an Abstract to this Session



Session ID#: 27139

Session Description:
It is widely recognised that the critical dynamics of evolution of catchment hydrological socio-ecological systems is determined by ‘slow’ variables, both biophysical and socioeconomic, and system thresholds determined by slow variables and if crossed, which cause the system to move into a new state. However, there exist obvious knowledge gaps in the understanding of the co-evolution of hydrological system, ecological system and societal system at catchment scale. These knowledge gaps include 1) Definition and measurement of societal variables at catchments; 2) Reconstruction of hydrological system, ecological system and societal system at catchments over different historical periods; and 3) Comparison of co-evolutionary trajectories of Hydrology-Society-Ecology System among different catchments. This session proposal calls for a science inquiry to address these knowledge gaps. It will welcome multiple disciplines’ studies including hydrology, ecology, economics, environmental history, environmental sociology, ecological anthropology, and also cover quantitative and qualitative methods and emerging data-mining techniques.
