As demand for fresh water rises and supply declines, a growing number of regions and localities, including cities, will be compelled to respond to water shortages. Therefore, this paper aims to examine the rationalization of water consumption utilizing demarketing strategies in the Gaza Strip (GS), Palestine. The population under study comprises the residents of the GS, amounting to approximately 2.1 million (2021) individuals. A survey among 372 respondents living and working in the five GS governorates, using a stratified random sample approach to mirror the population distribution, finds a significant relationship between consumer attitudes toward reducing water consumption and 5 key marketing variables (product, price, place, promotion, and people). Furthermore, four moderators reinforced these relationships, i.e., the perceived role of laws and legislations, perceived moral obligation, perceived water right, and institutional sentiment toward the water authority's management of water resources. Additionally, age, education level, marital status, and monthly income influence the effect of the demarketing mix on consumer attitudes toward reducing water consumption. This study informs managerial action and policy-making about the key variables to modulate in order to improve consumers' attitudes toward water rationalization and thus intrinsically motivate consumers to curb water consumption.</p></div>","PeriodicalId":48644,"journal":{"name":"Water Resources and Economics","volume":"43 ","pages":"Article 100227"},"PeriodicalIF":2.2,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49751973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By jointly estimating WTP and WTV, this study finds robust public support for improving the river in both time and monetary forms, although the proportion of respondents reporting positive WTV is higher. Wealthier households, however, prefer the payment option and are significantly less willing to contribute their time.

In particular, uncertainty surrounds the success of mitigation strategies and economic and demographic developments. While ‘grey’ measures, such as dikes and pumping, have been the dominant form of adaptation in the past against inland flooding, Nature-based Solutions are receiving more attention. However, evidence on their cost-effectiveness compared to grey alternatives is still limited. In this article, we develop a real options model that integrates climate change uncertainty as well as flexibility of the timing of investment. We expect that the uncertainty falls over time due to an increase in climate data that becomes available to the decision-maker. The decision-maker learns about climate change from two types of events: inland flooding and meteorological drought. The model is calibrated with data from the Oldambt–Eemskanaal–Dollardboezem water system in the Dutch Province of Groningen. Our results show the potential for Nature-based Solutions to become a viable alternative to dike heightening and pumping in addressing both extreme events. Moreover, we observe that the cost-effectiveness of Nature-based Solutions depends on the maturing time of the ecosystem, the value of land on which the measure is being implemented, and the type of information considered in the investment decision. We show that maturing times of up to nine years make a Nature-based Solution the preferred measure to invest in, even under strong beliefs of severe climate change. When maturing times exceed nine years, the option takes too long to become effective and pumping is preferred. Furthermore, our results show that an increase in the value of land on which a Nature-based Solution is being constructed may substantially reduce its cost-effectiveness. Finally, decision-making flexibility becomes valuable if expected damages from floods and droughts are sufficiently low and the decision-maker learns quickly about climate change.</p></div>","PeriodicalId":48644,"journal":{"name":"Water Resources and Economics","volume":"43 ","pages":"Article 100224"},"PeriodicalIF":2.2,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48822105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
