RESUMO

Groundwater is one of the main resources for social-ecological systems. As part of the total water cycle and deeply connected with land use, groundwater management faces many challenges, especially in coastal areas. Landscape Scale Planning is an emerging approach for land use planning providing a framework for management based on evidence, given that landscapes have physical and information flows. Landscape Scale Planning embraces the following three dimensions: (i) the spatial dimension centres on the recognition of distinct landscape units; (ii) the temporal dimension entails past, current and future uses of a landscape; and (iii) the modification dimension involves the anthropogenic alterations that affected and will affect the landscape and its features along the spatial and temporal dimensions. Through a systematic literature review of 28 selected publications, this paper explores how groundwater management can be improved through a Landscape Scale Planning approach. The results show that Landscape Scale Planning can be applied as an integrative framework for groundwater management. Landscape units based on, but not limited to, geology, topography, cultural and socio-economic aspects can aid groundwater management to consider the differing spatial and temporal characteristics of the aquifer. Landscape Scale Planning can also favour the inclusion of land use change dynamics in groundwater management processes. To this end, the paper proposes guidelines for applying Landscape Scale Planning to inform groundwater management and consider land use changes.

RESUMO

Water sensitive interventions are being promoted to reduce the adverse impacts of urban development on natural water cycles. However it is currently difficult to know the best strategy for their implementation because current and desired urban water performance is not well quantified. This is particularly at the city-region scale, which is important for strategic urban planning. This work aimed to fill this gap by quantifying the water performance of urban systems within city-regions using 'urban water metabolism' evaluation, to inform decisions about water sensitive interventions. To do this we adapted an existing evaluation framework with new methods. In particular, we used land use data for defining system boundaries, and for estimating natural hydrological flows. The criteria for gauging the water performance were water efficiency (in terms of water extracted externally) and hydrological performance (how much natural hydrological flows have changed relative to a nominated pre-urbanised state). We compared these performance criteria for urban systems within three Australian city-regions (South East Queensland, Melbourne and Perth metropolitan areas), under current conditions, and after implementation of example water sensitive interventions (demand management, rainwater/stormwater harvesting, wastewater recycling and increasing perviousness). The respective water efficiencies were found to be 79, 90 and 133 kL/capita/yr. In relation to hydrological performance, stormwater runoff relative to pre-urbanised flows was of most note, estimated to be 2-, 6- and 3- fold, respectively. The estimated performance benefits from water sensitive interventions suggested different priorities for each region, and that combined implementation of a range of interventions may be necessary to make substantive gains in performance. We concluded that the framework is suited to initial screening of the type and scale of water sensitive interventions needed to achieve desired water performance objectives.

RESUMO

Heatwaves kill more people than any other natural hazard in Australia. Current literature on managing health risks of heatwaves highlights the importance of implementing urban planning measures, and engaging with vulnerable groups on a local level to better understand perceptions of risk and tailor health protection measures. This paper reviews arrangements to reduce heatwave health risks in South East Queensland in response to these themes. A literature search and document analysis, stakeholder interviews, and multi-stakeholder cross-sectoral workshops revealed that although heatwave management is not always considered by local government and disaster management stakeholders, many urban planning measures to minimize urban heat have been pursued. However, greater information from vulnerable groups is still needed to better inform heatwave management measures.
