The East Bay Municipal Utility District (EBMUD) provides approximately 225,000 acre feet of water per year to 1.3 million people and 22,000 commercial, institutional and industrial accounts near San Francisco Bay, California. As part of its aggressive demand management program, EBMUD offers business customers on-site inspections and financial assistance to convert existing water using equipment and processes to more water efficient technology. EBMUD would like to:Interact with sponsors of new commercial sites before construction begins.Employ high efficiency water use technology at the beginning of the business operation rather than retrofitting equipment at a later date.Benefit the customer by improving production output while reducing operating costs involving water, sewerage and energy.Make more effective use of EBMUD rate payer dollars. This new approach is called: WaterSmart Guidelines for New Business and includes:A guidebook describing updated water efficient technology for fourteen water using technologies employed in twenty types of business operationsTechnical requirements and recommendations regarding water efficiency for designers of new business facilitiesChecklists of water efficiency measures to be used by officials considering new applications for water service.A marketing plan to reach prospective business customers

This paper provides details and the results of an evaluation study carried out on the largest residential demand management program in Australia, the Sydney Water Corporation (SWC) ‘Every Drop Counts’ (EDC) residential retrofit program. The evaluation measured the water savings of program participants and compared them to a control group. Savings of 20.9 ± 2.5 kilolitres per household per annum (kL/hh/a) were found from statistical analysis of water meter readings of the sample of single residential households analysed. These individual savings effectively provide SWC with a potential total saving of 3,344 ± 400 megalitres per annum (ML/a) for the single residential houses retrofitted alone, i.e. 80% of the 200,000 households retrofitted to date. The evaluation identified that no ‘decay’ in average savings were found over the maximum four year period assessed. Other factors evaluated during the study included: analysis of individual water efficiency measures; comparison of savings with other evaluations; and savings related to occupancy ratio, geographical grouping, income category and defined socioeconomic categories.

The article discusses the online marketing complex of tourism and socioeconomics of the online-tourist industry. The analytical data will enable to understand the current business trends in the competitive market today. The key objective of this research is to examine the eTourism developments around the world and in Greece as a country that is gradually embracing eCommerce. The prospect of the online-tourism is presented on the example of Greece tourism website InThessaloniki.com. The research reveals the features of tourism business and discusses important milestones in its development. Although it is rapidly becoming a growing topic of research, the information on the websites seems to be the only rescue for the researchers. At the same time, it forewarns and forearms the marketers of tomorrow about its importance as future mode of acquiring information and purchase of tourism products and services. The analyse of the socioeconomics of the online-tourist industry will enable to understand the current business trends that are more competitive in the market than the exists today. It will provide an opportunity to attract new business customers and receive additional profit. The author assumes that the analyses of the online- tourism market technologies have been instrumental in increasing the domain of awareness and accessibility while reducing the uncertainty with respect to communication gaps. With future high projections in all the spheres of tourism, it’s not gainsaying that technology can help us manage tourism operations better through ensuring high efficiency in working with clients, increase their loyalty and the sales rates of the company. The author analyse the socioeconomics, entrepreneurial activity, internal and external environment of the tourist industry.

Nuanced Understanding

Most of Australia’s capital cities and towns have been on water restrictions since at least 2007. As metropolitan and regional water supplies continue to dwindle in the southern regions of the continent, water managers will impose tighter conditions on the use of limited resources. It is thus important to examine human attachments to their outdoor spaces to better understand how residents will potentially respond to such policies. For policies designed to reduce the domestic consumption of limited resources to succeed, Australians must perceive them as equitable in both their design and outcome. An historical perspective on contemporary sustainability issues such as water scarcity is useful to explain how present-day values and behaviours towards resource use have been formulated, shaped and renegotiated by those experiences of preceding generations. As outdoor water use is an important focus of current water efficiency measures, a more nuanced understanding of the meanings historically invested in certain gardens can provide insights into how residents can react to disruptions in their watering routines. Using 1970s Perth, Western Australia as a case study through which to analyse such reactions, I argue that the water efficiency measures enacted by the then Metropolitan Water Board overlooked the variety of socio-cultural meanings attached to suburban gardens and as a consequence, affected households unequally.

Regional Water

The Sacramento California Region has long enjoyed ample water supplies and popular rivers providing esthetic, recreation and environmental resources. Ground and surface water supplies have been managed by twenty independent management agencies. In the 1980s and 1990s the region experienced dramatic population growth and increased water demand. Environmental organizations sought to preserve the environmental values of the Lower American River. Six years of negotiation resulted in the Water Forum Agreement, a memorandum of understanding signed by business and agricultural leaders, citizens groups, environmentalists, water managers, and local governments to fulfill two co-equal objectives: (i) to provide a reliable and safe water supply for the region's economic health and planned development to the year 2030; and (ii) to preserve the fishery, wildlife, recreational, and aesthetic values of the Lower American River. This paper describes three major parameters guiding the water future of the Sacramento Region, which may be a model for other regions of the world: (1) the seven policy elements of the Water Forum Agreement; (2) the Regional Water Authority (RWA) and the Sacramento Groundwater Authority help to implement the policies of the Water Forum Agreement; (3) RWA's regional water efficiency program provides “pick and choose” water efficiency measures to twenty water suppliers in three counties.

The City

In 1996, as part of Waitakere Council’s Water Cycle Strategy, a pressure standardisation programme to permanently lower the average supply pressure citywide was implemented with the aim of reducing water loss and water use. The experience gained during the 1994/95 Auckland water shortage had confirmed that there was considerable scope to reduce pressures in many areas. Since 1996 water pressures have been reduced in over 60% of the reticulated area of the city, with the average pressure reduced from 710 kPa to 540 kPa. As a result of this programme water loss from the network has been reduced, there has been a reduction in the frequency of mains breaks and it is likely that the life of water pipeline assets has been extended. Furthermore both pressure and demand management initiatives have reduced per capita water use in the city by more than 10%. A network computer model was used as a design tool to check the network under various pressure regimes and cost benefit analyses were carried out for various design scenarios. Fire sprinkler systems were checked as part of the design process. Minimum service standards were not reduced and in some cases pressures were actually increased. This paper covers the various aspects of the design, the implementation and the results of the pressure standardisation programme.

<p>The presentation will summarize the main findings of the chapter “Water”[1] of the report “Climate and Environmental Change in the Mediterranean Basin – Current Situation and Risks for the Future”. This report was published in November 2020 and prepared by 190 scientists from 25 countries, who belong to the scientific network “Mediterranean Experts on Climate and Environmental Change”.</p><p>Water resources in the Mediterranean are scarce, unevenly distributed and often mismatching human and environmental needs. Approx. 180 million people in the southern and eastern Mediterranean countries suffer from water scarcity (<1000 m<sup>3</sup> capita<sup>-1</sup> yr<sup>-1</sup>). The main water use is for agriculture, and more specifically on the southern and eastern rim. Water demand for both tourism and agriculture peak in summer, potentially enhancing conflicts in the future. Municipal water use is particularly constrained in the south and will likely be exacerbated in the future by demographic and migration phenomena. Northern countries face additional risks in flood prone areas where urban settlements are rapidly increasing.</p><p>Climate change, in combination with demographic and socio-economic developments, has mainly negative consequences for the water cycle in the Mediterranean Basin, including reduced runoff and groundwater recharge, increased crop water requirements, increased conflicts among users, and increased risk of overexploitation and degradation. These impacts will be particularly severe for global warming higher than 2°C.</p><p>Adequate water supply and demand management offers some options to cope with risks. Technical solutions are available for improving water use efficiency and productivity, and increasing reuse. Seawater desalination is increasingly used as adaptation measure to reduce (potable) water scarcity in dry Mediterranean countries, despite known drawbacks in terms of environmental impacts and energy requirements. Promising solar technologies are under development, potentially reducing emissions and costs. Reuse of wastewater is a solution for agriculture and industrial activities but also recharge of aquifers. Inter-basin transfers may lead to controversies and conflicts. Construction of dams contributes to the reduction of water and energy scarcities, but with trade-offs in terms of social and environmental impacts.</p><p>Overall, water demand management, which increases water use efficiency and reduces water losses, is crucial for water governance for a sustainable development. Maintaining Mediterranean diet or coming back to it on the basis of locally produced foods and reducing food wastes may save water but also carbon emissions while having nutritional and health benefits.</p><div><br><div> <p>[1] <strong>Fader M.</strong>, Giupponi C., Burak S., Dakhlaoui H., Koutroulis A., Lange M.A., Llasat M.C., Pulido-Velazquez D., Sanz-Cobeña A.

ABSTRACT The aim was to determine the efficiency of use of water and nitrogen for forage production and goat-milk production on an irrigated Tanzania Guineagrass (Panicum maximum cv. Tanzânia) pasture subjected to different management practices. The management levels tested were combinations among nitrogen fertilization levels and post-grazing residual heights (ResH): Intensive (ResH = 33.0cm and 600.0kg N/ha.year-1); Moderate (ResH = 47.0cm and 300.0kg N/ha.year-1); Light (ResH = 47cm and 0kg N/ha.year-1); and Conventional (ResH = 33cm and 0kg N/ha year-1). The efficiency of water use for forage production was higher in intensive and Moderate management. The Conventional management was recommended only for forage production since there is no nitrogen input available because this result was similar to Intensive management in water efficiency. The efficiency of water use to produce goat milk was higher in Intensive management. Moderate management presented higher efficiency of nitrogen to produce forage. On the other hand, Intensive management was more efficient using nitrogen in goat milk production. The amount of water needed to produce one liter of goat milk varied from 893.20 to 3,933.50L. In the moderate management, up to 121.48kg forage and 21.56kg of milk were produced for every kilogram of N utilized. Intensive management is advantageous for water use efficiency as well nitrogen efficiency to produce goat milk in cultivated pasture.
