The potential cumulative impact of coal mining and coal seam gas extraction on water resources and water-dependent assets from proposed developments in eastern Australia have been recently assessed through a Bioregional Assessment Programme. This study investigates the sensitivity of the Bioregional Assessment results to climate change and hydroclimate variability, using the Gloucester sub-region as an example. The results indicate that the impact of climate change on streamflow under medium and high future projections can be greater than the impact from coal mining development, particularly where the proposed development is small. The differences in the modelled impact of coal resource development relative to the baseline under different plausible climate futures are relatively small for the Gloucester sub-region but can be significant in regions with large proposed development. The sequencing of hydroclimate time series, particularly when the mine footprint is large, significantly influences the modelled maximum coal resource development impact. The maximum impact on volumetric and high flow variables will be higher if rainfall is high in the period when the mine footprint is largest, and vice-versa for low flow variables. The results suggest that detailed analysis of coal resource development impact should take into account climate change and hydroclimate variability.

The Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development (IESC) provides scientific advice to decision makers on the impact that coal resource development may have on Australia’s water resources. In particular, advice is provided on development proposals that have been submitted to the Australian Government and relevant state governments in the form of environmental impact statements (EISs). The Information Guidelines developed by the IESC outline the information considered necessary to enable the IESC to provide robust scientific advice to government regulators on the water-related impacts of coal resource development proposals. Proponents preparing EISs are strongly encouraged to consult the Information Guidelines before developing and submitting a proposal. The Information Guidelines have been updated for the first time since 2015 and will be presented. The update includes important and more detailed information about what types and the level of information that should be included in EISs. In addition a series of ‘explanatory notes’ have been developed which provide practical examples of how information should be presented in an EIS. The first two explanatory notes relate to uncertainty analysis in numerical groundwater modelling and how to undertake comprehensive assessments and manage impacts to groundwater dependent ecosystems. Two additional explanatory notes will be released for use later in 2018. The updated Information Guidelines are a continuing step towards improving the robustness of information provided to the IESC.

<p>Nature-Based Solutions (NBS) appear as some relevant alternatives to mitigate the consequences of climate change. For this reason, they are promoted for the implementation of the national plan for adaptation to climate change (PNACC) in France, in line with the Paris Agreement, the strategy of the European Union for adaptation to climate change and the French national strategy for biodiversity.</p><p>Nevertheless, this ambitious goal of democratizing NBS poses some institutional and technical challenges because many obstacles remain to their implementation. Overcoming these shortcomings is the objective of the LIFE integrated project called ARTISAN (Achieving Resiliency by Triggering Implementation of nature-based Solutions for climate Adaptation at a National scale). Coordinated by the French Biodiversity Office (OFB), its consortium regroups several local authorities, technical, research and education institutes.</p><p>For this purpose, ARTISAN is creating a framework promoting the implementation of NBS by improving scientific and technical knowledge about them, then by developing and disseminating relevant tools for project leaders (for the design, sizing, implementation and evaluation of ecosystem performance).</p><p>To demonstrate that NBS can respond to a diversity of climatic, ecological and institutional contexts, 10 pilot sites will be monitored in metropolitan and overseas France. The concerned issues are for example the reduction of urban heat island by the de-waterproofing of the public space, the limitation of the impact of cyclonic episodes on the urbanized coastline overseas by promoting the restoration of the mangrove, and the decrease of agricultural water stress during the low flow period by the hydromorphological restoration of wetlands. These pilot sites will serve to develop, improve and validate operational tools, methods and trainings devoted to practitioners.</p>

The streamflow has declined significantly in the coal mining concentrated watershed of the Loess Plateau, China, since the 1970s. Quantifying the impact of climate change, coal mining and soil and water conservation (SWC), which are mainly human activities, on streamflow is essential not only for understanding the mechanism of hydrological response, but also for water resource management in the catchment. In this study, the trend of annual streamflow series by Mann-Kendall test has been analyzed, and years showing abrupt changes have been detected using the cumulative anomaly curves and Pettitt test. The contribution of climate change, coal mining and SWC on streamflow has been separated with the monthly water-balance model (MWBM) and field investigation. The results showed: (1) The streamflow had an statistically significant downward trend during 1955–2013; (2) The two break points were in 1979 and 1996; (3) Relative to the baseline period, i.e., 1955–1978, the mean annual streamflow reduction in 1979–1996 was mainly affected by climate change, which was responsible for a decreased annual streamflow of 12.70 mm, for 70.95%, while coal mining and SWC resulted in a runoff reduction of 2.15 mm, 12.01% and 3.05mm, 17.04%, respectively; (4) In a recent period, i.e., 1997–2013, the impact of coal mining on streamflow reduction was dominant, reaching 29.88 mm, 54.24%. At the same time, the declining mean annual streamflow induced through climate change and SWC were 13.01 mm, 23.62% and 12.20 mm, 22.14%, respectively.

In 1963 Sydneysiders, having suffered four dismal summers in a row and wetter than usual weather during the 1950s, looked back to those lazy, hazy days of the summers of a distant past where the sky arched blue over the gleaming golden sand of the quintessential Australian beach. City dwellers in the dying months of 1963, worried by persistent rain and cool temperatures, concluded that soggy weather had become the established norm. More recent experiences of wet summers in Sydney have blamed this on La Niña—a short-term climate driver that brought heavy rains and flooding to many districts of eastern Australia. This article examines the impact of natural climate cycles on attitudes to weather in Sydney. It shows how an investigation of the cultural interface of weather and climate can illuminate attitudes that impact on our ability to plan for climate change into the future.

The boreal region has a subarctic climate that is subject to considerable inter-annual variability and is prone to impacts of future warming. Climate influences the seasonal streamflow regime which typically exhibits winter low flow, terminated by spring freshet, followed by summer flow recession. The effects of climatic variation on streamflow cannot be isolated with confidence but the impact of human regulation of rivers can greatly alter the natural flow rhythm, changing the timing of flow to suit human demands. The effect of scenario climate change on streamflow is explored through hydrological simulation. Example of a Canadian basin under warming scenario suggests that winter flow will increase, spring freshet dates will advance but peak flow will decline, as will summer flow due to enhanced evaporation. While this simulation was site specific, the results are qualitatively applicable to other boreal areas. Future studies should consider the role of human activities as their impacts on streamflow will be more profound than those due to climate change.

Abstract. The storage-discharge relations have been widely used for water resource management and have led to reliable estimation of the impact of climate change on water resources. In a previous study, we carried out a sensitivity analysis of the parameters in a discharge-storage relation in the form of a power function and found that the optimum parameters can be characterized by an exponential function (Fujimura et al., 2014). The aim of this study is to extend the previous study to clarify the properties of the parameters in the storage–discharge relations by carrying out a sensitivity analysis of efficiency using a hydrological model. The study basins are four mountainous basins in Japan with different climates and geologies. The results confirm that the two parameters in the storage–discharge relations can be expressed in an inversely proportional relationship. In addition, we can conveniently assume a practical function for the storage–discharge relations where only one parameter is used on the basis of the new relationship between the two parameters.

<p>Catchments of European mountains are essential because of their role to provide water to human society. Mountainous area regulate water flux through a complex system of storage and release, playing the role of water tower. Better understand the dynamic functioning of this system at the scale of each compartment and the relationships between the storage and releasing processes are important to understand the impact induced by climate change. In particular, the disappearance of snow during the winter will potentially modify the low flow water level and ecological flow in late spring and early summer, impacting the ecological services provided by e.g. ponds, peat or wetland. The presented study aims to identify the keys factors and their current role in this hydrological system of the Pyrenean Mountains, and identify critical hydrological conditions that will potentially impact the socio-ecological services related to water resources. This goal has been achieved by a development of a high resolution hydrological modeling framework at the scale of the entire Pyrenean massif, together with the study of lower scale representative systems (peatland) and the development of specific future climate scenarios, in order to suggest mitigation actions and adaptability action through water management.</p>
