Climate change is a key issue impacting on the resilience of natural resources and therefore requires a response by key natural resource management organisations such as the Goulburn Broken Catchment Management Authority.
The interactions between climate, natural resources, industries and communities are complex, interconnected and challenging to communicate and respond to.
Projections for the future climate in the Murray Basin region (of which the Goulburn Broken Catchment is part) will see average temperatures continue to increase in all seasons. By late in the century (2090), less rainfall is projected during the cool season with high confidence. There is medium confidence that rainfall will remain unchanged in the warm seasons. For the near future natural variability is projected to dominate projected change. Even though mean annual rainfall is projected to decline, heavy rainfall intensity is projected to increase with high confidence along with harsher fire-weather (Timbal, B et al. 2015. Murray Basin Cluster Report. CSIRO and Bureau of Meteorology, Australia).
All potential interactions between climate and natural resources need to be considered in climate change adaptation planning. This requires complex modelling, strategies and adaptive management to deal with uncertainty. In recognition of this, climate change is a ‘driver of change’ in the Goulburn Broken Regional Catchment Strategy 2013-2019.
The Goulburn Broken Catchment Management Authority aims to be a leader in working with the community to assist natural resources to adapt to climate change.
