“…A more positive finding is that the third most highly rated stressor was outdoor water use, which is highly likely to be impacted by land-use decisions, as described in Section 1.2. Indeed, water provides in both regions have introduced incentives for water conservation through landscape manipulation [40].…”

“…Meeting mandates to provide water in the short run seems to be central to the administration of urban water resources. Yet, if the frequency of drought and magnitude of droughts are expected to increase in the future as projected by several studies [12,37,40] then engaging practitioners-both land-use planners and water managers-in developing climate sensitive strategies can provide effective guidance to reduce short and long term impacts. Second, a realistic understanding of the scale of the issue is required.…”

Abstract:Largely because water resource planning in the U.S. has been separated from land-use planning, opportunities for explicitly linking planning policies to water availability remain unexamined. The pressing need for better coordination between land-use planning and water management is amplified by changes in the global climate, which will place even greater importance on managing water supplies and demands than in the past. By surveying land and water managers in two urbanizing regions of the western United States-Portland, Oregon and Phoenix Arizona-we assessed the extent to which their perspectives regarding municipal water resource management align or differ. We specifically focus on characterizing how they perceive water scarcity problems (i.e., stressors) and solutions (i.e., strategies). Overall, the results show a general agreement across both regions and professions that long-term drought, population growth, and outdoor water use are the most important stressors to urban water systems. The results of the survey indicated more agreement across cities than across professions with regard to effective strategies, reinforcing the idea that land-use planners and water managers remain divided in their conception of the solutions to urban water management. To conclude, we recommend potential pathways for coordinating the fields of land and water management for urban sustainability.

“…They also reported that water consumption increased slightly when maximum temperatures ranged between 4 and 21ºC, but that between 29 and 32ºC it increased three to five fold per degree of temperature. Breyer and Chang (2014) analysed the evolving response of daily water use to weather fluctuations for two Portland-area municipal water providers. They report that temperature sensitivity, the response of water use to a temperature increase, generally declined for both water providers.…”

The developed world has witnessed significant land changes since the second half of the 20th century. These include a process of intensive urban development, which is also accompanied by the growth in the urban population and housing. One of the outcomes of this process has been an increase in the consumption of resources, including water. The aim of this paper is to identify and analyse the factors affecting water consumption and the areas studied in water-stressed regions of the developed world. A literature review of territorial studies examining the factors that affect urban water consumption in these areas was conducted methodologically. The results reveal that: a) a significant number of papers have been written on water consumption factors in areas where there is substantial urban growth; and b) North America and Australia, have been compared to the rest of the developed world (especially Southern Europe), recently (since 2000s) due to the expansion of the low-density urbanism in the last few years.

“…Other outdoor water uses include pool top-ups, washing of cars, washing of hard surfaces, etc.. Water may also be used for small-scale urban agriculture -to grow edible plants like herbs, fruit and vegetables. Various climatic parameters impact outdoor water use, including, for example, rainfall, evapotranspiration and ambient temperature (Balling et al, 2008;Praskievicz and Chang, 2009;Breyer and Chang, 2014). This climatically-driven water use profile is particularly true for edible plants with seasonal growth.…”

Southern Africa is likely to experience higher evapotranspiration and altered rainfall characteristics due to global warming and climate change. Climate-driven water use may potentially stress water supply facilities due to increased demand and reduced surface water yield. This paper presents a conceptual theoretical framework for assessing impacts of climate change on domestic irrigation water use. The prediction of climatic conditions that may potentially influence future water use is reviewed together with regional capacity for downscaling global climate projections. The impact assessment of water use is based on the modification and adaptation of an existing end-use model for water demand to include parameters for climate change. The Penman-Monteith equation and the soil water balance equation are incorporated for the estimation of daily water needs of vegetated areas in residential properties. The paper also discusses data requirements and a calibration procedure to improve model fit to the observed domestic irrigation water use. The proposed approach could form a basis for constructing a detailed model for planning various adaption measures relating to climate-driven domestic irrigation water use.
