    Tapping into demand : a new approach to water supply in Vietnam
    (EEPSEA, IDRC Regional Office for Southeast and East Asia, Singapore, SG, 2005) IDRC Regional Office for Southeast and East Asia. EEPSEA
    A summary of EEPSEA Research Report 2005·RR3, Household demand for improved water services in Ho Chi Minh City : a comparison of contingent valuation and choice modeling estimates by Pham Khanh Nam and Tran Vo Hung Son, Environmental Economics Unit, University of Economics-HCMC, 1A Hoang Dieu Street, Phu Nhuan District, Ho Chi Minh City, Vietnam.

    Should Chile use renewables, fossil fuel or hydropower for future electricity supply? : evidence from a contingent valuation study
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba, CR, 2009) Aravena Novielli, Claudia
    Results of the study show that the introduction and development of renewable energy sources (RES) are supported by Chilean households, and preferable to continued use of fossil fuels or building large dams in Chilean Patagonia. The findings present a significant and positive willingness to pay premiums for the development of renewables. Using the Contingent Valuation Method, the study investigated the public’s preferences, attitudes and willingness to pay (WTP) premiums for the introduction and development of RES. Concerns over environmental goals and future energy security have boosted the Chilean government’s interests in alternative energy sources.

    Enforcement of water services payment for Mexican water utilities at the Mexico-US border
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba, CR, 2009) Aguilar Benitez, Ismael; Saphores, Jean-Daniel
    This policy brief reviews a study of the effect of enforcement policies on the collection efficiency of water utilities payments in the Mexico-US border region. Available data does not allow explanation of the causes of nonpayment at the household level. However, it is urgent to improve water services management in this region. Results suggest that more payment options may reduce the percentage of residential accounts in arrears. Only one state had clear water law rules for the implementation of disconnection and suspension of water services; this state also had the smallest percentage of residential accounts with overdue bills.

    Evaluation of the fuel conversion program in vehicles in the Aburrá Valley, Colombia
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba CR, 2008) Vergara, Carlos A.; Saldarriaga, Carlos A.
    The Aburrá Valley has high air pollution levels, and at various points the legal maximum levels of emissions are exceeded, with impacts on human well-being. The two-page policy brief provides insights regarding conversion/adoption of natural gas fuels in vehicles to offset emissions. It offers information towards a more general discussion on the implication of using economic incentives to encourage alternative fuels.

    Role of economic instruments for environmental management : water charges in the Paraia do Sul River Basin, Brazil
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba CR, 2007) Gustavo Féres, José
    Knowledge about water demand patterns is fundamental for evaluation of the impact of water charges as well as for the assessment of any demand-side management policy instrument. This two-page policy brief draws from a study project aimed at investigating water use patterns in the industrial and agricultural sectors, so as to inform water policy implementation in Brazil. Knowledge about the determinants of water reuse is required to assess the potential of water charges in inducing water saving investments.

    Environmental policy, fuel prices and the switching to natural gas in Santiago, Chile
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba, CR, 2007) Coria, Jessica
    To reduce air pollution in Santiago, switching to natural gas coincided with major new policy. The policy brief reflects on a study that analyzed factors driving the pattern of switching to natural gas in Santiago, and assessed the influence of environmental regulations and market forces. Emissions of particulate matter, which produce the worst health effects, were reduced by about 67%. To some extent, the lower price of natural gas worked as an economic instrument increasing the relative price of pollution.

    Economics of arsenic water pollution : a study from Bangladesh
    (SANDEE, Kathmandu, NP, 2007) Zakir Hossain Khan, M.; Bellamy, Rufus
    Bangladesh is facing a major health crisis because arsenic is poisoning a large percentage of the country’s drinking water. Although the government has taken a number of positive steps to address this challenge, much more work remains to be done as an estimated 28-50 million Bangladeshis are currently at risk from arsenic-contaminated water. To assess the economic case for dealing with this problem, a SANDEE study looks at the health impacts and costs associated with arsenic pollution and discusses the financial outlay needed to resolve the problem.

    Ground water irrigation and sustainability : water markets, institutions and power supply in Northern India
    (SANDEE, Kathmandu, NP, 2007) Banerji, A.; Meenakshi, J.V.; Khanna, Gauri; Bellamy, Rufus
    In South Asia concerns about water scarcity have been mounting for some time, particularly in rural areas where food productivity critically depends on irrigation. Sustainable water consumption is therefore a key development goal, otherwise any strategy that aims to guarantee food security or tackle rural poverty will ultimately fail. This is, however, a particularly big challenge as there are many factors that influence water supply and demand; this means that it is often difficult to decide what strategic approach should be taken to make sure that water sources are used efficiently and sustainably.
