Urban and rural communities affected by climate change; how can we mitigate the effects?

By David Holland

As we move towards 2030 AD, it is no longer a question of just finding ways to mitigate climate change (Garnaut, R. 2008), it is a call for the survival of our livelihood as we know it. The Bureau of Meteorology (BOM) benchmarks for 2030 for RCP 4.5 and RCP 8.5 are up to 190mm increase in sea level on 2005 levels, and up to a shocking 880 mm by 2090 under RCP 8.5. (Climate Change in Australia (1))

In coastal regions, the effects on urban areas is going to be enormous. There will be less frequent but larger storms with large storm surges. Potential the storms will cause inundate to large areas of low lying urban land.  (CSIRO and Bureau of Meteorology 2015)

If measures are not taken urgently to reassess settlement patterns, and the way we insure property assets, communities and all levels of Australian government can expect serious social and political discontent. (Holland 2012 Aug.: Holland (2015): Holland (2016 Feb.): NCCARF) The measures to reduce potential flood impacts and massive insurance claim costs, which are pushing up premium, would be to move urban areas away from hazardous zones. See Holland (2015)

Increasingly, daily temperatures and weather patterns are being affected by climate change. Recently, cyclone Debbie affected the whole east coast of Australia with flood and destruction. (Climate Council) In the summer of 2014 and 2017, the lower Hunter region of NSW was effected by mini cyclones which devastated the region.  In the summer of 2013 and in 2017, the Central Coast experienced very high temperatures. The 2017 event was experienced widely across NSW and Queensland. (BOM 2017: The CSIRO and Bureau of Meteorology’s 2015)

These events will continue to happen with more regularity. There is no remedy except to move to a more southerly location or stay indoors and have a good air conditioning system. To help conserve power, ensure that your home is fitted with solar panels and is well insulated.

Rural communities in Central NSW will experience more drought, less winter rains and more unpredictable extreme rain events. (Climate Change in Australia (2)) Winter rains often recharge the soil with moisture. Crops like cotton need that moisture for the summer planting season. (Holland 2016 Oct.)

In many places of the Darling River basin where irrigated crops are grown, water from the river will become depleted due to high use and evaporation rates. (Climate Change in Australia (2): Holland 2016)

As day temperatures rise, increased night time temperatures will damage the quality of the crop. Crop failures will potentially devastate communities due to the resulting economic down turn. (The CSIRO and Bureau of Meteorology’s (2015): Holland 2017)

Where high risk of crop failure and water shortages are likely due to climate effects, it would be up to the relevant State governments to take a proactive approach in mitigating the effects of climate change in these regions and ensure that alternate agricultural strategies are employed to avoid social disintegration. (Holland 2017)
