Colorado’s water supply is under threat due to climate change pressures and population growth, however Colorado has been recognized to have some of the most progressive water conservation programs in the country. Limiting outdoor water consumption is an increasingly popular approach to conserving water in semi-arid cities, yet in order to implement effective water reduction and conservation policies, more utilities and city managers need a firm understanding of the local drivers of outdoor water consumption. This research explores the drivers of outdoor water consumption in a semi-arid, medium-sized Colorado city that is projected to undergo significant population growth. We used a combination of correlation and linear regression analyses to identify the key descriptive variables that predict greater water consumption at the household scale. Some results were specific to the development patterns of this medium-sized city, where outdoor water use increased 7% for each additional mile (1.6 km) a household was located from the historic urban center. Similarly, more expensive homes used more water as well. Surprisingly, households with a higher ratio of vegetation cover to parcel size tended toward less water consumption. This result could be because parcels that are shaded by their tree canopy require less irrigation. We discuss these results to assist city managers and policymakers in creating water-efficient landscapes and provide information that can be leveraged to increase awareness for water conservation in a growing, semi-arid city.

Diverse Data

In this study, indoor water use at the United Arab Emirates University (UAEU) was assessed for three years (2016, 2017, and 2018). A geographic information system (GIS) was employed to determine where water use is high within the university, when and why water is used, who uses it, and how to minimize its usage. Diverse data were employed to elucidate the broad patterns of university water use. It was assumed that water use is directly proportional to the number of students and is lower during winter. The relationship between water use and number of students in academic buildings was modeled using least squares regression. The results indicate a low correlation between water use and the number of students, possibly due to the centralized usage of academic buildings and movement of students between them. The hypothesis of activity-driven consumption indicated that most water use occurred in residential buildings (47.5%), averaging 81.7 L per person per day (LPD). This value is lower than the metrics for dormitories in the United States (121 LPD) and Europe (143 LPD). A survey of 412 students revealed that half the respondents were not aware of water issues. Most of them (87%) preferred to drink bottled water and were not willing to use gray water for flushing (56%) or urinals (60%). The findings of this study will improve the understanding of university water use which will facilitate the development of effective water conservation policies and the establishment of such practices among the next generation.

Social and behavioral research is crucial for securing environmental sustainability and improving human living environments. Although the majority of people now live in urban areas, we have limited empirical evidence of the anticipated behavioral response to climate change. Using empirical data on daily household residential water use and temperature, our research examines the implications of future climate conditions on water conservation behavior in 501 households within the Portland (OR) metropolitan region. We ask whether and how much change in ambient temperatures impact residential household water use, while controlling for taxlot characteristics. Based on our results, we develop a spatially explicit description about the changes in future water use for the study region using a downscaled future climate scenario. The results suggest that behavioral responses are mediated by an interaction of household structural attributes, and magnitude and temporal variability of weather parameters. These findings have implications for the way natural resource managers and planning bureaus prepare for and adapt to future consequences of climate change.

This paper reviews water requirements and the alternatives for water conservation in small, relatively remote northern communities. Requirements are examined in terms of basic needs and desires for sanitation from an individual household and a community perspective. Presented are factors which influence water use such as the method of delivery, household plumbing, socio-economic aspects, rate structure, climate and plumbing codes. Similarly, factors which influence water conservation are identified. Outlined in detail are current methods of reducing water use within the northern household.

Water Scarce

Hotels are a fundamental component within the tourist Spanish sector, and their role in water management turns out even more relevant taking into account the fact that tourist areas, in which they are generally located, are water scarce. Trying to go further from the standard ratios and estimations to plan water conservation, this work intends to really measure and quantify water use in rooms. Only by doing this, can subsequent conservation actions, now able to be reliably specified for each specific use, achieve a real success.

<p>The agriculture sector is one of the largest users of water and a significant source of greenhouse gas (GHG) emissions. The development of low-GHG-emission and water-conserving agriculture will inevitably be the trend in the future. Because of the physiological differences among crops and their response efficiency to external changes, changes in planting structure, climate and input of production factors will have an impact on regional agricultural water use and GHG emissions. This paper systematically analyzed the spatial-temporal evolution characteristics of crop planting structure, climate, and production factor inputs in Heilongjiang Province, the main grain-producing region of China, from 2000 to 2015, and quantified the regional agricultural water use and GHG emissions characteristics under different scenarios by using the Penman-Monteith formula and the Denitrification-Decomposition (DNDC) model. The results showed that the global warming potential (GWP) increased by 15% due to the change in planting structure. A large increase in the proportion of rice and corn sown was the main reason. During the study period, regional climate change had a positive impact on the water- saving and emission reduction of the agricultural industry. The annual water demand per unit area decreased by 19%, and the GWP decreased by 12% compared with that in 2000. The input of fertilizer and other means of production will have a significant impact on GHG emissions from farmlands. The increase in N fertilizer input significantly increased N<sub>2</sub>O emissions, with a 5% increase in GWP. Agricultural water consumption and carbon emissions are affected by changes in climate, input of means of production, and planting structure. Therefore, multiple regulatory measures should be taken in combination with regional characteristics to realize a new layout of planting structure with low emissions, water conservation, and sustainability.</p>

Minimization of water use and reuse applications within industry has recently gained importance within the context of water conservation efforts. The leather tanning industry is one of the subject industries due to large amount of water to be disposed of together with a high pollution load. The leather tanning industry has a complex structure in terms of materials, processes and manufacturing practices. Therefore a systematic approach is required to assess water use practice. In this study, bovine leather processing was taken as an example. An extensive study was conducted as on-site evaluations and questionnaires in the İstanbul Organized Leather Tanning District to assess water use practices, patterns and minimization trends. Results of the study were discussed and important aspects of water minimization practices have been pointed out.
