Qualitative Responses

Despite water scarcity and high agricultural water consumption in the Middle East and North Africa region, substantial amounts of treated wastewater are discharged into seas without proper utilization. This can be attributed to either farmers' unwillingness to use or to pay for reclaimed wastewater. Therefore, a field survey was conducted in Jordan and Tunisia, which are considered as representative to the MENA region, using a prepared and pilot tested questionnaire. This study applies the contingent valuation method to elicit the willingness of farmers to pay for reclaimed wastewater. Logistic regression analysis is applied in an attempt to build a model that correlates qualitative responses of farmers to monetary stimuli. The water price seriously affects farming profitability and farmers' willingness to pay for reclaimed wastewater. Farmers prove to be unwilling to pay more than 0.05 $/m3 of reclaimed wastewater primarily because of quality concerns, comparatively easy access to freshwater, and price.

Despite water scarcity and high agricultural water demand in the Middle East and North Africa region, substantial proportions of treated wastewater are discharged into the environment and seas without proper utilization. All countries of the region, low pricing of reclaimed wastewater is a common tool to make reuse attractive. However, low pricing of reclaimed wastewater is ineffectual due to farmers' access to freshwater for irrigation at low tariff. Therefore, increasing the prices of freshwater in such a way that does not jeopardize feasibility of agriculture would promote irrigation with reclaimed wastewater even at increased prices. On one hand, it increases the gap between the price of freshwater and that of reclaimed wastewater, making the later more attractive. On the other hand, it would be used as a financial resource for funding the investment costs of the infrastructure needed for conveyance and distribution of reclaimed wastewater. This paper studies the viability of increasing the prices of freshwater and reclaimed wastewater. The results show that irrigation with reclaimed wastewater even for restricted irrigation can be as profitable as, and sometimes better than, freshwater irrigation. Some of the permitted crops such as fruit trees can be more profitable than vegetables. Thus, it appears that the level of knowledge farmers and others on the benefits of reclaimed wastewater is still limited.

Solutions for mitigating and reducing environmental pollution are important priorities for many developed and developing countries. This study was conducted to better understand the degree to which inner-city citizens and foreigners perceive air pollution and respond to it, particularly how much they willingly contribute to improving air quality in Vietnam, a lower-middle-income nation in Southeast Asia. During mid-December 2019, a stratified random sampling technique and a contingent valuation method (CVM) were employed to survey 199 inhabitants and 75 foreigners who reside and travel within the inner-city of Hanoi. The data comprises four major groups of information on: (1) perception of air pollution and its impacts, (2) preventive measures used to mitigate polluted air, (3) commitments on willingness-to-pay (WTP) for reducing air pollution alongside reasons for the yes-or-no-WTP decision, and (4) demographic information of interviewees. The findings and data of this study could offer many policy implications for better environmental management in the study area and beyond.

Reuse Of Treated Wastewater

The present chapter reports on a practical case of decision making in agricultural TWW reuse. The studied site concerns the Cebala TWW irrigated perimeter in Tunisia, located in North Africa. Crucially though in this perimeter is that TWW is under-exploited. Thus, the proposed research dwells on the future of this perimeter which could oscillate between hope and deadlock. In case of hope, shall we improve the quality of the resource and possibly move to the tertiary treatment? And in case of deadlock, shall we give up the TWW reuse or substitute it by a conventional resource? To make an evaluation of this experience, the authors first gave a general overview of the descriptive study in a dashboard. Contingent valuation method was used to assess qualitative data and gauge the intangible effects. Then, the authors presented a systemic multicriteria method deployed to make decision-making process easier. Such a method or technique, which is grounded on Lp metrics, is called Compromise Programming.

Descriptive Statistical Analysis

Increased public concern and awareness of health and environment, is expected to significantly increase organic rice consumers. Thus, it can be consumed and reached by more people. The objectives of the study were to identify the characteristics of organic rice consumers, measure willingness to pay of organic rice consumers and analyze the factors related to the willingness to pay of organic rice consumers. The method used in this study is a survey method with descriptive statistical analysis and Contingent Valuation Method (CVM). The numbers of research respondents were 51 people consisting of organic rice consumers in Warung Sehat 1000 Kebun (W1000K) as much 18 people and consumers of organic rice in several other places joined in the Indonesian Organic Community as much 33 people. The results showed that consumers were willing to pay up to 10% higher than the price offered for organic rice type of pandan wangi, menthik susu, red rice and brown rice sold in W1000K. Even in some other places, consumers are willing to pay for those rice at prices higher up to 22% of the offered price. While for organic rice type of black rice, consumers are willing to pay 9%-11% lower than the price offered. Factors related to consumers' willingness to pay more for organic rice are health (67%), food security (45%), impact on the environment (43%), knowledge of organic rice (39%), easy access to get rice (37%), service (33%), quality (25%), packaging (24%), price (20%), and lifestyle (18%).

Science-based desirable solutions for mitigating and or reducing environmental pollution are of important priorities for many developed and developing countries. This article is conducted to better understand how well the inner-city citizens and foreigners perceive air pollution, how well they respond to it, and how much they willingly contribute to improving air quality in Vietnam, a lower-middle-income nation in Southeast Asia. During late 2019, a stratified random sampling technique and a contingent valuation method (CVM) were employed to survey 199 inhabitants and 75 foreigners who reside and travel within the inner-city of Hanoi, respectively. The data comprises four major groups of information, including (1) perception of air pollution and its impacts, (2) preventive measures used to mitigate polluted air, (3) commitments on willingness-to-pay (WTP) for reducing air pollution alongside reasons for the yes-or-no-WTP decision, and (4) demographic information of interviewees. The data could offer many attributes and policy implications for better economics and environmental management in the study area and or in similar places around the world.

The volume of Treated Wastewater (TW) produced in Oman is increasing, due to increased connection of houses to the sewage network and increased construction of wastewater treatment plants. Despite 68% of the TW been used for irrigating urban landscapes, 10.3 Mm3 TW has been discharged to the sea in 2014. Wastewater treatment plants are owned and operated by private companies, which aspire to sell excess TW, particularly to farmers, in order to recover cost of wastewater treatment. This paper has used the Contingent Valuation Method (CVM) to estimate the farmers’ Willingness to Pay (WTP) for TW for farm irrigation. Seventy two farmers responded to a face-to face interview on eliciting WTP to purchase TW as irrigation water, out of a total population of 400 farmers in Seeb region who have farms in proximity to a wastewater treatment plant. The results indicated that farmers’ WTP for TW was on average 0.111 OR/m3. WTP for TW was significantly affected by the income of farmers and whether the farm is a market oriented or non-market hobby oriented farm. The percentage of farmers willing to pay the average price or higher was 38%. Most farmers are not willing to pay the price currently charged by the wastewater treatment company for landscaping irrigation (0.220 OR/m3) given the large volumes required for farm irrigation. Even rich farmers maintaining hobby farms are willing to pay only 0.128 OR/m3 versus 0.087 OR/m3 by the market oriented farmers. The WTP for TW is higher than the prices reported (OR 0.005 to 0.023 OR/ m3) for groundwater used in agriculture in Oman. .

Based on the concept of a livable and global age-friendly city, pavements are a public facility that the city should provide to the people. Appropriate pavements will be beneficial for the people, particularly for good quality of life for the elderly to move around in the city. This study explored the behaviour of the elderly in the use of pavements and the problems confronted. The study also evaluated the value of the pavement walking area as it reflected the benefits of pavements to the elderly by applying the Contingent Valuation Method (CVM). During March-May 2017, data were collected using interviews with 601 elderly living in Bangkok. The study indicated that the main problem for senior citizens regarding their use of pavements was from being disturbed by motorbikes riding on the pavements. The average value of pavement for the elderly was about THB 160 (USD 5.30) per person per year. Thus, the benefits of pavements to the elderly in Bangkok was approximately THB 158 million (USD 5.2 million) per year. Thus, policy makers should make proper budget allocations for elderly-friendly pavement management and seriously address the problems confronting the elderly in using pavements, to maximize the usefulness of pavements not only for the elderly but also for the public and to support a sustainable urban development.
