This paper examines the Nelson Mandela Bay public’s willingness to pay (WTP) for the removal of a local undesirable land use, the manganese ore dumps and the oil tank farm situated within the boundaries of the Port Elizabeth harbour, Eastern Cape, South Africa, by means of the contingent valuation method. Both a non-parametric and parametric estimate of the WTP is derived. Estimated WTP for the removal of this disamenity ranges from R47.09 to R93.21 per household. The aggregate WTP ranges from R13 489 683 to R26 701 496. Due to the sensitivity of the parametric estimate of WTP to functional form specification and the distribution of the random part of preferences, the less restricted non-parametric WTP estimate (R47.09) is more appropriate. The results of this study show that policy-makers should take heed of the importance communities attach to the location of pollution-creating activities in urban areas.

The present study estimates the farmers’ willingness to switch to organic agriculture by using the one-and-one-half-bound dichotomous choice contingent valuation method. We survey 200 farmers in the Kwangsi-myeon, Yesan-gun (Chungnam, Korea) and ask them at what revenue level (based on a 40 kg bag of eco-friendly rice) they would be willing to switch from the conventional agricultural methods to organic agricultural methods. The Turnbull model, a non-parametric method, was then used to estimate the willingness to switch to organic agriculture. The presented results show that farmers would be willing to convert to organic agriculture if their revenues were increased to 107 369–109 230 KRW per bag from the reference value of 60 000 KRW.

Hydroelectric power plants and dams often play an important role in developing countries in terms of their contribution to economy. In accordance with the energy policies of Turkish Republic, Yusufeli Dam and Hydroelectric Power Plant in Northeastern Turkey have been initiated. In this study, the Contingent Valuation Method (CVM) was conducted in Yusufeli Village to determine the environmental costs of the Yusufeli Project. The purpose is to assess the willingness to pay (WTP) of Yusufeli Village residents for restoration of the environmental impacts of the dam project and also to investigate the underlying economic, psychological, and social motivations for WTP. WTP was calculated as US$761 per person which can further be used in the cost–benefit analysis. The results from the study suggest that application of the CVM in rural and urban areas located in the same region can show differences.

This paper discusses cost of unreliability of electricity supply to the residential customers. Electricity supply outage cost is evaluated by customers' survey technique for urban and semi-urban residential areas of a developing country. The energy consumption pattern of urban and sub-urban areas is determined. Electricity supply outage cost is evaluated using both preparatory action approach and contingent valuation method. A detailed breakdown of customer's average outages costs for a entire day based on 8 three-hourly time durations are obtained that give easily understandable figures to the utilities. The power consumption pattern obtained are in close agreement with the utility's load curve. A MATLAB based computer program using Least Square Error Approximation is used to evaluate the outage cost.

ABSTRACT This study highlighted the role that an informal market plays in shielding unemployed rural migrants in urban areas from unemployment-induced poverty using the Nelson Mandela Bay Municipality (NMBM) informal Prickly Pear Market as a case study. The purpose of this study was to show how earnings from self-employment or informal employment can be effective in reducing poverty. The Sustainable Livelihoods Framework was used as the theoretical basis for unpacking the household socioeconomic factors that influenced the informal prickly pear marketers’ decision to engage in the market. The study found that despite the prickly pear’s short-term availability, the income was channelled towards school supplies and sustained households during the month in addition to social grants, especially after the grant income had finished. The study aimed to revive interest in the Opuntia ficus-indica species, as one of the ways by which poverty can be reduced in the Eastern Cape.

Our cities are often characterised by a complex, ungrammatical articulation of spaces, volumes, intended uses, and values. The residual green urban areas are representative of a low level or absence of order, but above all, of functions and values. The study proposes a new methodological and operational approach to the rehabilitation of green residual urban areas, participatory type that can generate a new order between values, functions and actors, to mediate private and public needs, to promote new forms of responsibility and thus to implement some of the priority objectives set out in the 2030 Agenda. The operational tools supporting the approach are the Contingent Valuation Method (CVM), public and private partnership (PPP) and crowdfunding. This approach supported the selection of the project and the creation of a budget with public and private funding to support the participatory rehabilitation of a residual green urban area in the municipality of Acireale. The amount of funding identified largely covers rehabilitation costs. The issue of the quality and quantity of urban greenery is crucial for the sustainability and resilience of cities to climate change. Rehabilitation of remaining urban green areas is an opportunity to meet the new needs of green areas, supporting communities in this new challenge.

Management of solid waste is a major challenge in urban areas of most parts of the world, especially in developing countries. The study aimed to determine and estimate the willingness to pay (WTP) of the selected households for the improvement of solid waste management in Vietnam. The research evaluated WTP of household solid waste in case studies in Bien Hoa and My Tho cities using contingent valuation method (CVM). The data were collected through a closed-ended questionnaire survey and interviews with 200 households. The results showed that the most willingness to pay was equal to 10,000 and 15,000 VND per month. The respondents were willing to pay in Bien Hoa and My Tho with an average of 14,450 VND (0.63 USD) and 13,000 VND (0.56 USD) per month, respectively. Regression model identified influential factors on WTP of households in the two cities of Vietnam. The factors that significantly influence households’ WTP were monthly household income, education of respondents, age, occupation and solid waste volume (p<0.05). The results of this study can be used for the urban planning and implemented the sustainable development process in Bien Hoa and My Tho cities.

The purpose of the study is to estimate the air quality improvement in the urban areas of HoChiMinh City (HCMC) through resident’s willingness to pay (WTP) by using contingent valuation method. 300 residents were chosen to participate in an interview with the structured questionnaire and the open-ended question about their WTP. The results show that with the performance of ambient air in HCMC, 88.41% of respondents are willing to pay for this "particular commodity". The average WTP for a 50% reduction of concentration of air pollutants in next 5 years in HCMC, where respondents live and work was 19,732 VNĐ/household/month, accounted 0.15% of a household income. Positive WTP values reveal that residents have a choice between better air quality and rapid growth of the economy, which also means that air quality is really their considerable economic value. Therefore, this value should be considered in the cost – benefit analysis of projects or programs relating to air quality. The results are the source of useful information for policy makers to decide in the investment and policy measures to reduce impacts on air quality in the process of economic development.

The increasing population in Indonesia is directly proportional to the growth of new settlements. In line with this, the growth of waste volume in Indonesia is closely related to the growth of its population. The level of welfare and lifestyle in Indonesia has resulted in a significant increase in waste generation, especially in urban areas. Jatihandap is one of the areas in Mandalajati Subdistrict, Bandung City that increases the influence of waste generation by each people and wants to improve the quality of its waste services to reduce these impacts. One way that can be done to measure the willingness of citizens to improve waste services is to measure the Contingent Valuation Method. Contingent Valuation Method (CVM) Based on the results of this study, WTP values were 138 people from 153 samples selected. The estimated WTP (EWTP) is Rp. 12,971 and the total WTP (TWTP) is Rp. 80,385,000 / month. Based on multiple linear regression analysis, the WTP value of Jatihandap Urban Village is influenced by the amount of garbage contributions and gender equality from the results of the questionnaire that has been done.
