Climate Change Impact Risk Matrix

The process of developing the impact risk matrix is a structured way of identifying impacts, risks and opportunities associated with climate change. This matrix describes the impacts of climate change variables on elements of region’s assets. The colour coding shows either the negative (brown) and positive (blue) impacts, as determined by the panel of regional technical experts. Darker degrees of the brown and blue identify impact risk of greater magnitude, that have been assessed by considering the likelihood and consequence of these impacts occurring.


For biodiversity and vegetation, the regional technical expert panel identified five indicators that were of key importance. The key issues identified in this matrix include: water availability and the competition for water resources, altered fire regimes, changes in vegetation structure, a decrease in suitable habitat for fauna, an increase in pressure on refugia by pest species, loss of refugia, loss of microhabitats and loss of pollinators.

Climate Change Vulnerability Matrix

The vulnerability risk matrix identifies adaptation responses to the risks of climate change and determines the level of vulnerability. Vulnerability is influenced by both impact risk and adaptive capacity. This matrix describes the way in which the region’s assets could respond to the risks identified in the impact risk matrix. The colour coding in each cell shows the degree of vulnerability, white indicates no vulnerability, light brown (low vulnerability), middle shade of brown (moderate vulnerability) and dark brown (high vulnerability).
