There has long been a great deal of interest in methods for analyzing energy use and energy use intensities. Many methods developed within energy studies are also applicable in other areas where materials use is of interest, but in several cases these methods have not been applied to other materials.
This paper investigates two complementary pieces of data on households’ demand for improved water services, coping costs and willingness to pay (WTP), from a survey of 1500 randomly sampled households in Kathmandu, Nepal. We evaluate how coping costs and WTP vary across types of water users and income.
This paper discusses the practical problems of implementing water policy and pricing reforms in
transition economies by looking at the case of Odessa, Ukraine. Chief among the policy advice for the
water and sanitation (W&S) sector in less developed countries is greater cost-sharing by customers through
increased service prices, with the goals of encouraging more efficient water use by users, promoting a
greater perceived stake among customers in the health of their W&S systems and enabling service providers
This paper examines whether the benefits of the Melamchi water supply
project in Nepal are likely to exceed its costs, assuming that high-quality municipal
water services can be delivered to households and firms in the urbanized part of
the Kathmandu Valley. Monte Carlo simulations are used to explore the sensitivity
of the net present value and economic internal rate of return calculations to a wide
range of assumptions and input parameters.We find that extreme assumptions are
This paper analyzes the welfare effects of improved health status through increased water quality using a choice experiment. The survey was administered to a random sample of households in metropolitan Cairo, Egypt.
We examine households' demand for improved water services in Kathmandu, Nepal, where the government is considering the possibility of involving the private sector in the operation of municipal water supply services. We surveyed a randomly selected sample of 1500 households in the Kathmandu Valley and asked respondents questions in in-person interviews about how they would vote if given the choice between their existing water supply situation and an improved water service provided by a private operator.
A contingent valuation survey was conducted in Kumasi, Ghana, to estimate households' willingness to pay for two types of improved sanitation services: improved ventilated pit latrines and water closets connected to a sewer system. Over 1200 randomly selected households throughout the city were interviewed.
Most people in Onitsha, Nigeria obtain their water from an elaborate and wellorganized
water vending system which is run by the private sector. About 275 tanker trucks
collect water from private boreholes and sell it to households and businesses equipped with water
storage facilities
