Water Meters

In response to droughts, various media campaigns and water-saving instructions are released. However, these often only have temporary water conservation effects. A promising development in this regard is Digital Water Meters (DWM), which can provide near real-time water-use feedback. Despite extensive DWM experience in some water-stressed regions, a profound understanding of the initial attitude towards DWM and message-tailoring opportunities are rarely empirically explored. This study aims to obtain insights into the attitude towards the introduction of DWM and explore opportunities for message tailoring, a topic of extra relevance as we may be on the threshold of a large-scale DWM implementation in many world regions. Messages tailored to (i) normative beliefs and attitudes on drinking water, (ii) water-use activity and (iii) phase of decision-making, seem particularly compatible with DWM. Through a survey (n = 1037) in the Netherlands, we observe that 93% of respondents have no objections if their utility invests in DWM and that 78% would accept a (free) DWM because of improved leakage detection, lower costs and environmental considerations. Finally, instead of sociodemographic factors, we observe that an attitude-based customer segmentation approach is an especially useful predictor of respondent’s motivation to endorse DWM and forms a promising basis for water conservation message-tailoring strategies.

Water Meters

Depletion and contamination of traditional water supplies and population pressures are straining the water resources of the United States. This has placed increased emphasis on the need for water conservation through all phases of the use cycle. Objectives of this research were to: 1) Determine water use in residential, commercial, and institutional landscapes; 2) Evaluate landscape irrigation system performance; and 3) Evaluate feasibility of landscape irrigation scheduling. Beginning in 1991, water meters on 18 test sites in Lincoln, NE were read on a weekly basis. Water meter readings during the winter were used to develop a baseline on non-landscape water use. The “can test” method was used to evaluate landscape irrigation system precipitation rate and distribution efficiency. Four recording weather stations were used to estimate daily potential evapotranspiration (ETp). Lysimeters (20 cm dia. × 31 cm deep) were installed in two Kentucky bluegrass and one tall fescue landscape to estimate water use coefficients for calculating landscape evapotranspiration. Irrigation system Christiansen coefficients of uniformity ranged from .43 to .87 with scheduling coefficients ranging from 1.31 to over 15.14. Poor irrigation system performance characteristics made it difficult to schedule irrigation on estimated water use.

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.

The global reaction to US President Donald Trump's executive order, “Protecting the Nation from Foreign Terrorist Entry into the United States” of January 27, 2017,1 revealed great public sympathy for the fate of refugees and the principle of refugee protection. In the case of Europe, such sympathy has, however, been dismissed by politicians who have read concerns regarding security and integration as reason for introducing restrictive policies on asylum and humanitarian assistance. These policies are at odds with public sentiment. Drawing upon public opinion surveys conducted by Amnesty International, the European Social Survey (ESS), and Pew Global Attitudes Survey across the European Union and neighboring states, this article records a marked divide between public attitudes towards the treatment of refugees and asylum seekers and official policies regarding asylum and humanitarian assistance, and seeks to understand why this is the case. The article suggests that post-9/11 there has been a reconfiguration of refugee policy and a reconnecting of humanitarian and security interests which has enabled a discourse antithetical to the universal right to asylum. It offers five possible explanations for this trend: i) fears over cultural antagonism in host countries; ii) the conflation of refugees and immigrants, both those deemed economically advantageous as well as those labelled as “illegal”; iii) dominance of human capital thinking; iv) foreign policy justification; and v) the normalization of border controls. The main conclusion is that in a post-post-Cold War era characterized in part by the reconnecting of security and humanitarian policy, European governments have developed restrictive policies despite public sympathy. Support for the admission of refugees is not, however, unqualified, and most states and European populations prefer skilled populations that can be easily assimilated. In order to achieve greater protection and more open policies, this article recommends human rights actors work with the United Nations High Commissioner for Refugees (UNHCR) and its partners to challenge the above discourse through media campaigns and grassroots messaging. Further recommendations include: • Challenging efforts to normalize and drawing attention to the extreme and unprecedented activities of illegal and inhumane practices, e.g., detention, offshore processing, and the separation of families through the courts as part of a coordinated information campaign to present a counter moral argument. • Identifying how restrictive asylum policies fail to advance foreign policy interests and are contrary to international law. • Evidencing persecution by sharing information with the press and government agencies on the nature of claims by those currently considered ineligible for refugee protection as part of a wider campaign of information and inclusion. • Engaging with minority, and in particular Muslim, communities to redress public concerns regarding the possibility of cultural integration in the host country. • Clarifying the rights of refugees and migrants in line with the UNHCR and International Organization for Migration (IOM) guidelines and European and national law in order to hold governments to account and to ensure that all — irrespective of their skills, status, nationality or religion — are given the opportunity to seek asylum. • Identifying and promoting leadership among states and regional bodies to advance the rights of refugees.

Large-scale vegetation restoration greatly changed the soil erosion environment in the Loess Plateau since the implementation of the “Grain for Green Project” (GGP) in 1999. Evaluating the effects of vegetation restoration on soil erosion is significant to local soil and water conservation and vegetation construction. Taking the Ansai Watershed as the case area, this study calculated the soil erosion modulus from 2000 to 2015 under the initial and current scenarios of vegetation restoration, using the Chinese Soil Loess Equation (CSLE), based on rainfall and soil data, remote sensing images and socio-economic data. The effect of vegetation restoration on soil erosion was evaluated by comparing the average annual soil erosion modulus under two scenarios among 16 years. The results showed: (1) vegetation restoration significantly changed the local land use, characterized by the conversion of farmland to grassland, arboreal land, and shrub land. From 2000 to 2015, the area of arboreal land, shrub land, and grassland increased from 19.46 km2, 19.43 km2, and 719.49 km2 to 99.26 km2, 75.97 km2, and 1084.24 km2; while the farmland area decreased from 547.90 km2 to 34.35 km2; (2) the average annual soil erosion modulus from 2000 to 2015 under the initial and current scenarios of vegetation restoration was 114.44 t/(hm²·a) and 78.42 t/(hm²·a), respectively, with an average annual reduction of 4.81 × 106 t of soil erosion amount thanks to the vegetation restoration; (3) the dominant soil erosion intensity changed from “severe and light erosion” to “moderate and light erosion”, vegetation restoration greatly improved the soil erosion environment in the study area; (4) areas with increased erosion and decreased erosion were alternately distributed, accounting for 48% and 52% of the total land area, and mainly distributed in the northwest and southeast of the watershed, respectively. Irrational land use changes in local areas (such as the conversion of farmland and grassland into construction land, etc.) and the ineffective implementation of vegetation restoration are the main reasons leading to the existence of areas with increased erosion.

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.

Abstract Background Many southern African countries are nearing the global goal to diagnose 90% of people with HIV by 2020. In 2016, 84% and 86% of people with HIV knew their status in Malawi and Zimbabwe respectively. Despite this progress, gaps remain, particularly among men (≥25 years). We investigated awareness, use and willingness to HIV self-test (HIVST) prior to large scale implementation and explored sociodemographic associations. Methods We pooled responses from two of the first cross-sectional Demographic Health Surveys to include HIVST questions: Malawi and Zimbabwe in 2015-16. Sociodemographic factors and sexual risk behaviours associated with previously testing for HIV, and awareness, past use and future willingness to self-test were investigated using univariable and multivariable logistic regression, adjusting for the sample design and limiting analysis to participants with completed questionnaire and a valid HIV result. Analysis of willingness to self-test was restricted to Zimbabwean men, as Malawians and women were not asked this question. Results Of 31 385 individuals, the proportion never-tested was higher for men (31.2%) than women (16.5%), p<0.001. For men, having ever tested increased with age. Past use and awareness of HIVST was very low, 1.2% and 12.6% respectively. Awareness was lower among women than men (9.1% vs 15.3%, adjusted odds ratio (aOR)=1.55; 95% confidence interval [CI]: 1.37-1.75), and at younger ages, and lower education and literacy levels. Willingness to self-test among Zimbabwean men was high (84.5%), with having previously tested for HIV, high sexual risk, and being ≥25 years associated with greater willingness. Wealthier men had greater awareness of HIVST than poorer men (p<0.001). Men at higher HIV-related sexual risk, compared to men at lower HIV-related sexual risk, had the greatest willingness to self-test (aOR=3.74; 95%CI: 1.39-10.03, p<0.009).Conclusions In 2015-16 many Malawian and Zimbabwean men had never tested for HIV. Despite low awareness and minimal HIVST experience at that time, willingness to self-test was high among Zimbabwean men, especially in older men with moderate to high HIV-related sexual risk. These data provide a valuable baseline against which to investigate population-level uptake of HIVST as programmes scale-up. Programmes introducing, or planning to introduce HIVST, should consider including questions in population-based surveys.
