    A Case study on economic valuation of environmental services provided by the Bolgoda Lake Sri Lanka Phase I
    Bhuvendralingam, S; Chanmugam, S; Wadugodapitiya, WO; Gunaruwan, TL; Jayawardena, K; Kotagama, HB; Sivagnanasothy, V
    In the recent past, several countries in Asia have demonstrated robust economic growth, largely led by industrialization. A consequence has been rapid urbanization. About 30 percent (800 million people) of the total population in Asia, live in urban areas (cities and towns). This demographic shift towards a larger urban population is accelerating. It is expected that by year 2025, about 60 percent of the Asian population (2.5 billion people) will be living in urban areas. The number of large urban cities is growing rapidly in the region. Currently, there are nine megacities (those with the population of the more than 8 million) in Asia, and their number is expected to increase to 13 by the year 2000. The concentration of industrial activities and large populations in Asian cities have caused environmental problems with serious consequences that undermine the gains from growth to human welfare. Awareness to consider environmental conservation as an essential goal of development is increasing. Governments, the private sector, community groups are responding with a variety of initiatives such as investment on environmental management, controls on investments having potential to pollute the environment, encouraging the use of environment friendly technology, and creating awareness among population on need for urban environmental conservation. The physical magnitude of urban environmental degradation has been reasonably analyzed and understood. The economic impact of environmental degradation, however, has not been adequately analyzed, degradation has not been considered for rational policy-making. This leads to anomalies in prioritization of investments and selection of environmental management strategies and policies to economically efficiently mitigate environmental degradation

    Sri Lanka industrial estate siting study
    Wijesekera, NTS; Bhuvendralingam, S; De Alwis, A; Butler, J; Smythe, R
    Expansion and diversification of the existing industrial base in Sri Lanka are major components of the country’s economic development policy. Though increased industrialization holds the promise of an improved economy, it may accompany numerous environmental and social risks if executed in an improper manner. The siting ot industrial estates that are designed and operated with appropriate infrastructure and environmental controls is the best possible approach to minimize these risks.

    Water qualilty monitoring and modelling in the Kelani Ganga
    Bhuvendralingam, S; Hettiarachchi, SSL
    Draft ambient water quality standards based on designated water uses have been developed for surface waters of Sri Lanka in the period 1991-1992. These standards are to be used to evaluate present environmental quality, to prepare environmental management plans, and to assess environmental impacts due to effluent discharge from future development activities. Evaluation of present environmental quality requires water quality monitoring. Prediction of the effect of current and future effluent discharge requires the use of water quality models - providing the relationship between waste loads and receiving water quality.
