    Household environmental conditions and disease prevalence in Uganda : the impact of access to safe water and improved sanitation on diarrhea
    (Centre for Environmental Economics and Policy in Africa (CEEPA), University of Pretoria, Pretoria, ZA, 2010) Kasirye, Ibrahim
    Findings show that only piped-in water and access to private covered pit latrines significantly impact diarrhea prevalence in households. Providing community standpipes results in the largest reduction in the burden of disease. However, although water in Uganda is publicly provided, the construction of sanitation facilities is considered a private matter. Consequently, national policies that address the lack of toilets have the potential to reduce diarrhea-related diseases and morbidity rates. Data was drawn from the 2005/06 Uganda National Household Survey to investigate the impacts of inadequate access to safe water and improved sanitation, and the potential gains from undertaking various interventions.

    Who switches to gas? : a study of a fuel conversion program in Colombia
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba, CR, 2008) Saldarriaga I., Carlos Adrían; Vergara T., Carlos Andrés
    Air pollution from mobile sources is an important environmental problem in larger cities in Colombia, as well as in other Latin-American countries. In 2001, a program was implemented to encourage the use of natural gas in vehicles in the Aburrá Valley in Colombia, with incentives to convert small cars from gasoline and diesel to hybrid engines with natural gas, most notably a cash subsidy. Using a survey administered to both commercial and private car owners we study the determinants of conversion under this fuel conversion program. We thus obtain information about the reasons for adoption of new technologies in vehicles. This allows us to discuss the possible outcomes of this type of policy. Results show that a large part of owners who switched would have done it anyway without the subsidy. Based on the findings, commercial vehicles are most likely to be converted to natural gas vehicles (NGV).

    Water reuse in Brazilian manufacturing firms
    (Latin American and Caribbean Environmental Economics Program (LACEEP), Turrialba, CR, 2007) Féres José; Reynaud, Arnaud; Thomas, Alban
    This paper examines the factors influencing manufacturing firms' water reuse decision and analyzes whether the structure of intake water demand differs between firms that adopt water reuse practices and those which do not. The first stage of the estimation model involves a Probit analysis of the water reuse decision and the second stage employs an endogenous switching regression to estimate the intake water demand equations. Results suggest that water charges may act as an effective mechanism in inducing firms to undertake water reuse investments and in reducing intake water demand. Estimates of the water demand price elasticities indicates that plants that reuse water are more sensitive to water price increases than plants without access to reuse technologies.

    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
    In this study I analyze the pattern of adoption of natural gas in Chile and the drivers behind it. For doing that I have a panel data set of stationary sources from 1995 to 2005 that allows me to identify either the role of environmental policy as the impact of the energy cost inducing the switching to this clean fuel. Besides, I evaluate the performance of the system of environmental contingencies, a non- traditional policy instrument created in Chile in the early nineties, that seemed strongly correlated with the switching. According to the data most of the adoption of natural gas was induced by the lower cost of this fuel, showing that sources were more sensitive to the cost of energy than to the environmental regulation.

    Managing the arsenic disaster in water supply : risk measurement, costs of illness and policy choices for Bangladesh
    (SANDEE, Kathmandu, NP, 2007) Zakir Hossain Khan, M.
    Arsenic poisoning is a major public health concern in Bangladesh. This study uses primary data to examine health impacts and costs associated with arsenic contamination of groundwater. The study estimates that some 7 to 12 million person-days per year are lost as a result of arsenic exposure. In addition, individuals who are sick spend between 207 (US$ 3.5) million to 369 (US$ 6.25) million taka per year for medical help. The total cost of illness as a result of exposure to arsenic is Tk 557 (US$ 9) to Tk 994 (US$ 17) million per annum or on average nearly 0.6 percent of the annual income of affected individuals. If it is possible to provide arsenic-free (within safe limit) alternative technologies to reverse the impact of arsenic, the social gains to Bangladesh are considerable. The study also finds that the threat of Melanosis--the black spot disease—and Keratosis—roughness in palms and soles— is high when there is cumulative exposure and that this threat is not the same for all wealth classes. Richer households take mitigation measures to reduce the threat on their health. Richer households also seem to be more successful in avoiding the incidence of conjunctivitis due to Arsenicosis. Women on the other hand are more likely to be affected by inflammation of the respiratory tracts--a sign of long-term exposure without recourse to medical help.

    Valuing groundwater's supporting services to ecosystems in Heihe River Basin
    (College of Environment and Resources, Beijing, CN, 2006) Junlian, Zhang
    The study aims to: identify and analyse ecosystem services supported by groundwater resources; estimate the economic value of the ecosystem services supported by the groundwater; find sustainable groundwater-conserving policy incentives financed by the economic value of conservation; and make policy recommendations for conserving groundwater in Zhangye City. Located in the arid and desert areas in northwest China, Zhangye City consists of many oasis ecosystems watered by the Heihe River. For valuation of groundwater resources, this study applies the Contingent Valuation Method (CVM).
