The pressure on water infrastructure has increased due to an increase in the number of aging water pipes. Aging pipes are prone to failure, causing significant financial losses and service disruptions. The increasing number of aged pipes and limited budget for pipe rehabilitation or replacement necessitates water infrastructure asset management to ensure sustainable water supply services. In this study, contingent valuation was used to estimate the willingness to pay (WTP) and value improved water supply services through the implementation of asset management. To estimate the WTP at the individual and county levels, we performed a nationwide survey including eight provinces and 24 counties/cities with distinct water supply service performances. At the individual level, the median WTP estimated using the double-bounded dichotomous choice model was 249.50 KRW/month (0.22 USD/month). The results showed that high-level satisfaction of customers with water supply services and positive price perception of water bills resulted in a high WTP. At the county level, decreasing water supply service performances were associated with a low WTP, indicating that proper interventions by local utilities are required to achieve sustainable water supply services. Our results provide a quantitative basis for decision-making in implementation of water infrastructure asset management.

“…There are different instruments used to measure economic impact. Among others, we can highlight the General Computable Balance model (Dynamic computable general equilibrium model) (Tchouamou & Seetaram, 2018), Cost-Benefit Analysis (Hong et al, 2018), Contingent Valuation (Contingent Valuation analysis) (Guerrini et al, 2018), and the Input-Output Tables. When choosing a methodology, the available data, the type of approach to be carried out according to the type of event, the objectives to be achieved, the positive and negative aspects of each type of method, and the clarity and precision of the results obtained according to the type of instrument that is applied must be taken into consideration.…”

The Fruit and Vegetable Sector in Andalusia (Spain): Key in Terms of Linkages and the Effect of Economic Multipliers?

et al. 2023

The agriculture, livestock, forestry, and fishing sectors are very important in Andalusia (Spain), being strongly focused on foreign markets, which has required them to make great efforts to improve their competitiveness. The aim of this work is to understand the interrelationships between the fruit and vegetables sector and the remaining sectors of the Andalusian economy, as well as knowing its multiplying effects on production, income, and employment. To this end, the input-output tables of Andalusia for 2016 will be used in order to know if it is a key sector and how it can help to establish economic policy objectives. Regarding forward linkages, the branches that most demand fruit and vegetable products are the industries related to other food products, and the preparation of canned fish and vegetables. In relation to backward linkages, they focus on the manufacture of basic chemicals, and other agricultural crops and services. Despite its importance in Andalusian agriculture, the fruit and vegetable sector is not considered a key sector according to the Rasmussen coefficients, as it is classified as an independent industry. The reasons may be that it uses few primary inputs, is poorly integrated with the rest of the productive sectors, and its production is destined to satisfy final demand (national and international). However, it generates an above average impact on the economy in most multipliers, being important for stimulating economic policy measures.

“…This study evaluated public acceptance of the project by means of the Contingent Valuation Method (CVM). This attempts to determine the market price of non-market goods and services, and is the most widely-used method in evaluating environmental assets [15] by surveying peoples' willingness to pay (WTP) for such an asset and/or what they would be willing to receive by way of compensation in order to tolerate such a cost, i.e., preservation of a natural park, the upgrading of a wastewater treatment plant or the restoration of a damaged area via infrastructure development [16][17][18][19][20]. An example of CVM applied to evaluate the non-market value of reclaimed wastewater for reuse in agriculture is provided by [21] in a Spanish study.…”

This paper presents and discusses the results of a study carried out in Ecuador, where the zootechnical sector represents one of the country’s most important economic activities. It is, however, the source of many environmental problems, including the release of untreated liquid effluents and odorous emissions, and the production and disposal of solid wastes. The main aim of this study was to propose a treatment train for the zootechnical farm wastewater, combining natural systems (i.e., lagoons and subsurface flow beds) with conventional technologies and a cost-benefit analysis. With reference to a specific case study, the different steps of the treatment train were designed and the corresponding construction, operational and maintenance costs evaluated. To better assess the technical and economic feasibility of such a proposal, a cost-benefit analysis was carried out. The social benefit was evaluated by means of the contingent valuation method and a focus on the methodology and collected results was reported. The main findings discussed, in terms of selected treatments, their costs, and the financial and economic analysis of the project, could be useful for administrators, decision-makers and all technicians involved in planning and management of zootechnical farm wastewaters in developing countries, in particular in Latin America.
