“…Many studies have investigated the impact of climate change on hydrology over large basins (Githui et al 2009;Chen et al 2012;Silberstein et al 2012;Zhang et al 2012;Liu et al 2013;Li et al 2014). For example, Chen et al (2012) assessed the impacts of climate change on runoff change trend based on CGCM2 under A2 and B2 scenarios over the Yangtze River.…”

Six global climate models (GCMs) from Coupled Model Intercomparison Project Phase 5 under three Respectively Concentration Pathways (RCP2.6, RCP4.5 and RCP8.5) were used to assess the impact of climate change on streamflow for the Huangnizhuang catchment (HNZ) in China. Change factor method was used for bias correction between GCM outputs and observations and the SWAT model was used to simulate the hydrological processes. The results indicated that the SWAT model performed well in the study catchment with a monthly Nash-Sutcliffe efficiency (NS) of 0.93 and 0.91 and daily NS of 0.63 and 0.68 for calibration and validation periods respectively. Their corresponding relative errors were -2.2 and 8.9, and -2.6 and 8.5 % respectively. The ensemble of multi-GCMs projected an increase of precipitation in the middle and end of twenty-first century over the HNZ, ranging from -2.4 to 9 %. However, streamflow is likely to decline in the future, ranging -6.9 to 0.8 %, mainly due to an increase of evapotranspiration in a warming world, as air temperature shows steadily increases for all the GCMs and RCPs. Average monthly streamflow from six GCMs are likely to increase in August and September but decline from October to June. The associated uncertainties of the reported results were also discussed. It includes, but is not limit to, different GCMs, emissions scenarios, downscaling techniques as well as hydrological simulations. The results of this study can inform planning of long-term basin water management strategies taking into account global change scenarios.

Abstract:In this secondary research, published works on effect of climate change on water resources in other countries and in Australia were reviewed critically. Research question, objectives and assumptions were made to facilitate this study. First, methods used for such studies and their results at global level were reviewed. Then Australian specific methods of study and findings were reviewed. More commonly, both globally and in Australia, simulations using long-term real data on selected climatic scenarios of global climatic models are projected for long-term future trends. The validity and certainty of predicted occurrences depend upon the closeness of real time data with scenarios to which they are projected. Even with these limitations, projections of already rising temperatures and declining rainfall on surface water and ground water availabilities show gradual decline in water availability leading to water stress both for human communities and ecosystems The role of human-induced emissions in hastening the degradation process has also been investigated. Conserving all available water, practising efficient water consumption and prudent water policies only can provide some relief from what is inevitable.

“…The future impacts of climate change on dryland cropping systems have been widely studied in different agricultural regions (Thomas 2008, Xiao et al 2010, Ö zdogan 2011, Gohari et al 2013, Sommer et al 2013, including Australia (Ludwig and Asseng 2006, Anwar et al 2007, Luo et al 2009, Asseng et al 2011, Barlow et al 2013. Countries with Mediterraneantype climates, particularly semiarid regions like the grain belt of southwestern Australia, appear to be most vulnerable to climate change and the subsequent reduction in water resources (Ali et al 2012, Silberstein et al 2012. Although the overall frequency of frost events is likely to decrease with rising temperature, drier atmospheric conditions may result in radiative frosts earlier in the growing season (Zheng et al 2012).…”
