“…Furthermore, this finding is supported by the logistic regression model (Table 6) in which household income is one of the significant variables that determined the probability of the respondents' WTP (correlation coefficient 0.281; p<0.001). This outcome aligns with the previous findings of Xiong et al (2018), Mumbi andWatanabe (2020), andHao et al (2023), who similarly identified income and bid price as notable determinants impacting WTP, wherein respondents with a higher income were more willing to pay than their counterparts. Aside from the bid price and monthly household income, other variables that affect the respondents' willingness to vote in favor of a particular bid were also presented in Table 6.…”

Lakes are recognized as highly susceptible to the impacts of various anthropogenic activities, making them one of the most vulnerable aquatic ecosystems. These ecosystems frequently experience degradation due to the lack of policies recognizing the importance of their often overlooked regulating ecosystem services. A contingent valuation approach was employed to assess the stakeholders’ willingness to pay (WTP) for the restoration of the water quality of a eutrophic lake using the case of Tadlac Lake, situated within the municipality of Los Baños, Laguna Province, Philippines. The findings of the study revealed that households in the area expressed a WTP of Php 95.88/household/month or Php 1,150.56/household/year (1 USD=55.89 Php), with 72.30% of respondents indicating their readiness to support efforts to improve the water quality of Tadlac Lake. The likelihood of a positive response significantly varied depending on factors such as the offered price, gender, educational attainment, duration of residency, household size, income, and the method of questionnaire administration (cheap talk vs. non-cheap talk). These results underscore the community’s favorable disposition towards investing in improving Tadlac Lake’s water quality. This valuation study contributes a fresh perspective on lake management strategies. Moreover, it emphasizes the importance of environmental education regarding social-ecological dynamics as a crucial requirement for crafting comprehensive policies that will steer sustainable management of natural lake resources.

“…This finding was in line with earlier research, which reported that environmental concern and awareness require efforts to improve environmental factors (Rousseau and Deschacht, 2020;Severo, 2021;Barouki, 2021;Rume and Islam, 2020;Vanapalli et al, 2021;Cheval et al, 2020). (Wang et al, 2006;Akhtar et al, 2017, Hao et al, 2023. It is also consistent with research reporting that household income has a positive (+) relationship with WTP, as well as previous findings that the cost of environmental improvements is considered a significant variable for WTP (Akhtar et al, 2017;Casey et al, 2006;Osiolo, 2017;Liu et al, 2018).…”

Background and objective: This study aimed to assess satisfaction with environmental factors during the COVID-19 pandemic and key factors affecting the willingness to pay (WTP) for environmental improvements using logistic regression analysis.Methods: Cross-sectional survey data of 504 residents of Taean-gun in Chungcheongnam-do (South Chungcheong Province), taken from July to August 2020, were used.Results: The assessment of their satisfaction with five environmental factors found that their satisfaction with the natural ecology had the highest score, while their satisfaction with the waste factor had the lowest score. With respect to overall environmental satisfaction, it was found that regardless of gender, age, and income, most residents were highly satisfied with the overall environment of Taean-gun (Taean County). In addition, the WTP for environmental improvements was slightly higher among males than among females. Residents in their 60s or older and with a monthly income of 4 - 4.99 million won were most likely to express WTP for environmental improvements. A binominal logit analysis found that increased environmental concerns (EC), satisfaction with environmental health (EHS) and income were crucial factors in determining the WTP for environmental health. The variables of increased EC and income, have a positive (+) relationship with WTP, while the variable of EHS has a significantly a negative (-) relationship with WTP.Conclusion: In other words, the higher the EC, the lower the EHS, and the higher the income, the more likely residents were to express WTP for environmental improvements. This study has significance in that it can provide primary data for sustainable local environmental plans to improve public environmental awareness for sustainability, and environmental strategies to prepare for post-pandemic life.

“…Moreover, a higher WTP is observed for respondents who believe that improvements in climate change response and community integration values are vital. The trend of a higher WTP for higher-income households was commonly observed in previous studies [15,24,28,35,[61][62][63][64]. The higher WTP in households with more household members can be attributed to the potential inconvenience faced by households with children or elderly members if there is a disruption in the water supply.…”

“…Some studies focus on various projects to improve water quality. Kwak et al [24] and Hao et al [15] directly estimate the WTP for an enhanced water quality in specific study areas. Additionally, Kontogianni et al [25] and Paola et al [26] consider upgrading or ex-tending the operation time of wastewater treatment plants.…”

“…Therefore, evaluating parallel pipeline projects for a better water supply should not be merely based on economic factors, such as costs and bills. Previous studies often utilized survey-based methods, including the contingent valuation method (CVM), to analyze the value of projects imposed by consumers based on their willingness to pay (WTP), using samples collected from the directly affected area [13][14][15][16][17][18].…”

Parallel pipeline projects can contribute to ensuring a safe and stable water supply and preventing or mitigating losses caused by water pipeline accidents. However, because these projects require a significant investment, feasibility tests are essential prior to their implementation. Considering the public nature of the water supply, the direct beneficiaries of the project and people from other regions can place value on such projects. Thus, this study estimates the value of parallel pipeline projects using the contingent valuation method (CVM) and the swing weighting technique. We constructed two contingent valuation surveys: one asking about the willingness to pay (WTP) for a parallel pipeline project within the respondent’s region and the other asking about the WTP for a project outside the region. The results show that the annual WTP per household for projects within and outside the region was 113,669 KRW (87.98 USD) and 5493 KRW (4.25 USD), respectively. These results indicate that the value perceived by people from outside the region should be considered. Additionally, the results from the swing weighting technique and WTP analysis show that the values that respondents generally consider important and those that can leverage the overall project value are distinct. This study’s results provide insights into the implementation of parallel pipeline projects in South Korea. Furthermore, this study’s analytical framework can be used for the valuation of other public infrastructure projects.
