“…A study from South Africa estimates a benefit-cost ratio of 3.1 for small-scale water schemes [ 142 ]. A study from Indonesia compared three wastewater treatment interventions and finds limited economic rationale for the interventions [ 143 ]. On the other hand, a broader cost-benefit study at the river basin level estimated the benefits of cleaning up the Upper Citarum River in Indonesia exceeded costs by 2.3 times [ 140 ].…”

Safe drinking water, sanitation, and hygiene (WASH) are fundamental to an improved standard of living. Globally, 91% of households used improved drinking water sources in 2015, while for improved sanitation it is 68%. Wealth disparities are stark, with rural populations, slum dwellers and marginalized groups lagging significantly behind. Service coverage is significantly lower when considering the new water and sanitation targets under the sustainable development goals (SDGs) which aspire to a higher standard of ‘safely managed’ water and sanitation. Lack of access to WASH can have an economic impact as much as 7% of Gross Domestic Product, not including the social and environmental consequences. Research points to significant health and socio-economic consequences of poor nutritional status, child growth and school performance caused by inadequate WASH. Groundwater over-extraction and pollution of surface water bodies have serious impacts on water resource availability and biodiversity, while climate change exacerbates the health risks of water insecurity. A significant literature documents the beneficial impacts of WASH interventions, and a growing number of impact evaluation studies assess how interventions are optimally financed, implemented and sustained. Many innovations in behavior change and service delivery offer potential for scaling up services to meet the SDGs.

“…The CBA provides a systematic process to justify the economic feasibility by bringing elements of transparency and objective water resource management (Prihandrijanti et al 2008). By using the CBA approach, a lot of the controversy surrounding environmental valuation has been the subject of debate, due to the overly restrictive valuations (Brouwer 2000).…”

The water quality in Ko Chang Marine National Park coast has been problematic for many years. Recently, a conservation plan has been made by the local government for protecting the ocean beaches by constructing a sewage treatment plant in the region. This study uses the contingent valuation method (CVM) to measure the benefits associated with the proposal of the wastewater treatment plant (WWTP), followed by conducting cost-benefit analysis (CBA) in order to justify the feasibility of the public fund appropriation by the government fiscal policy, such as taxes. A completed questionnaire survey of 300 randomly clustered households was analyzed. Household willingness to pay (WTP) was estimated using Tobit models. The results indicate that the mean WTP for the proposed wastewater treatment project is $73.36 per household per year, translating into an aggregate monetary benefit of $298,774 per year for the local community. Additionally, the CBA result shows that the net present value (NPV) of the project attains $465,162.48 per year, internal rate of return (IRR) reaches 9.14 %, and benefit-cost ratio (B/C) ends up with 2.21 with all those intangible benefits excluded from the calculation. Therefore, the proposed wastewater treatment plant project is economically profitable.

“…In addition, internet search and follow-up of other sources revealed the following additional studies: 2 book chapters, 8 peer-reviewed published journal articles outside PubMed, and 8 other reports. This gives a total of 50 economic evaluation studies reviewed in this paper in the fi elds of water, sanitation and hygiene (13 studies), vector control (16 studies) and air pollution (21 studies), presented in Tables 1, 2 and 3, respectively. For WSH interventions, the 13 studies found are distributed between 2 for drinking water supply alone [26,27], 4 for sanitation alone [28][29][30][31], 2 for hygiene alone [32,33], and 5 for combined WSH interventions [25,[34][35][36][37]. Previous reviews of studies also summarize the economic evidence-base [38,39].…”

“…A good example is the global study on low cost solutions for improving drinking water quality, where 5 solutions are compared [26]. Another good example is the comparison of three sanitation options in an urban area of Indonesia [30]. On the other hand, some economic studies group technical options into a single intervention arm [27,29,32,34,36 ], thus only increasing understanding of overall cost-benefi t (e.g.…”

Economic Evaluation of Environmental Health Interventions to Support Decision Making

Environmental burden of disease represents one quarter of overall disease burden, hence necessitating greater attention from decision makers both inside and outside the health sector. Economic evaluation techniques such as costeffectiveness analysis and cost-benefi t analysis provide key information to health decision makers on the effi ciency of environmental health interventions, assisting them in choosing interventions which give the greatest social return on limited public budgets and private resources. The aim of this article is to review economic evaluation studies in three environmental health areas-water, sanitation, hygiene (WSH), vector control, and air pollution-and to critically examine the policy relevance and scientifi c quality of the studies for selecting and funding public programmers. A keyword search of Medline from 1990-2008 revealed 32 studies, and gathering of articles from other sources revealed a further 18 studies, giving a total of 50 economic evaluation studies (13 WSH interventions, 16 vector control and 21 air pollution). Overall, the economic evidence base on environmental health interventions remains relatively weak-too few studies per intervention, of variable scientifi c quality and from diverse locations which limits generalisability of fi ndings. Importantly, there still exists a disconnect between economic research, decision making and programmer implementation. This can be explained by the lack of translation of research fi ndings into accessible documentation for policy makers and limited relevance of research fi ndings, and the often low importance of economic evidence in budgeting decisions. These fi ndings underline the importance of involving policy makers in the defi ning of research agendas and commissioning of research, and improving the awareness of researchers of the policy environment into which their research feeds.
