| This paper discusses algal blooms in waterways from an externality perspective. Algal activity is directly related to phosphorus intake, but this can vary by season and by degree of dilution. Policy alternatives, including property rights, taxes, tradeable permits and water pricing are discussed. Issues relating to detergent control and technological approaches are presented. |

| Tea has been Sri Lanka’s major export earner for several decades. However, soil erosion on tea‐producing land has had considerable on‐site and off‐site effects. This study quantifies soil erosion impacts for smallholder tea farms in Sri Lanka by estimating a yield damage function and an erosion damage function using a subjective elicitation technique. The Mitscherlich‐Spillman type of function was found to yield acceptable results. The study indicates that high rates of soil erosion require earlier adoption of soil conservation measures than do low rates of erosion. Sensitivity analysis shows the optimum year to change to a conservation practice is very sensitive to the discount rate but less sensitive to the cost of production and price of tea. |

| The Regional Forest Agreement (RFA) programme introduced in the 1990s, in Australia to protect environmental values, encourage job creation and growth and manage forests in an ecologically sustainable manner. Multi-criteria Decision Analysis (MCDA) techniques were used in this study to assess their potential for examining the RFA policy. The empirical study of the North East Victoria RFA using MCDA attempted to explore the potential of these techniques. The results indicate that the old-growth forest is the most valued attribute and timber production appeared important. The most preferred forest land management option was option A with a high level of conservation and low level of native timber extraction which differed from the government option for North... |

| There has been substantial focus on water resource development in India, but with emphasis mainly on the technical side. Development of institutions to manage the interactions and arrangements necessary has received little attention. The study uses the new institutional economics framework and governance theories to probe local institutions in water resource management. 29 institutions and 450 households are covered and the data analysed through univariate Anova and multivariate Tobit regressions. The results show the importance of technical, organizational and political governance provided by the institutions. Achievement of efficiency, equity, environment and finance objectives depends substantially on lowering transaction costs through advancing means... |
