Drought is expected to occur 20 - 40 percent more often in most of Australia over the coming decades.6, 18 If our heat - trapping emissions continue to rise at high rates, 19 more severe droughts are projected for eastern Australia in the first half of this century.6, 17 And droughts may occur up to 40 percent more often in southeast Australia by 2070.2 Unless we act now to curb global warming emissions, most regions of the country are expected to suffer exceptionally low soil moisture at almost double the frequency that they do now.3 Studies suggest that climate change is helping to weaken the trade winds over the Pacific Ocean, with the potential to change rainfall patterns in the region, including Australia.20, 21,16,22
Natural processes changed the timing and magnitude of soil moisture, streamflow, and groundwater deficits by up to several years, and caused the amplification of rainfall declines in streamflow to be greater than in normal dry years.
Food availability could be threatened through direct climate impacts on crops and livestock from increased flooding, drought, shifts in the timing and amount of rainfall, and high temperatures, or indirectly through increased soil erosion from more frequent heavy storms or through increased pest and disease pressure on crops and livestock caused by warmer temperatures and other changes in climatic conditions.
A team of Berkeley Lab researchers has performed molecular level analysis of desert biological soil crusts — living ground cover formed by microbial communities — to reveal how long - dormant cyanobacteria become activated by rainfall then resume dormancy when the precipitation stops.
These services — which include biodiversity maintenance, rainfall generation, carbon sequestration, and soil stabilization, among others — have traditionally been undervalued by markets, but there are signs that the situation is changing.
