The mining industry must operate often in remote or harsh locations being forced to deal with extreme conditions such as floods, heatwaves, storms and droughts. Consequently, mines commonly build ‘down time’ into production schedules and incur costs to manage the various risks and impacts arising from climate extremes.
As many environmental conditions change, risk management based on past experience and past data may be increasingly ineffective. This challenge is coupled with increasing market demand for fewer interruptions. Stakeholder activism is driving some companies to address these issues as part of good corporate governance.
Hence, adaptation to climate is becoming an important strategic move for many companies. The drive to remain competitive and reduce climate related risks, while mitigating and climate impact is growing.
To date, CSIRO has surveyed the industry twice, performed mining industry workshops SA, WA and Qld and developed tools to help decision making. For example, the ‘climate related adaptation from terrain evaluation results’ (CRATER) method identifies flood-potential hot-spots around a mine and helps to select suitable adaptation options. We are currently developing a value chain vulnerability assessment tool specifically for the mining industry, based on a previous tool, successfully used by the food industry. Additionally we are developing the CRATER tool as a stand-alone application whilst also developing CRATER II that includes future climate scenario assessments.
