Hydrobiological study of Dahikhuta reservoir

Physico-chemical parameters and the algae of Dahikhuta reservoir, near Malegaon, Dist. Nasik (Maharashtra) have been investigated during July to December 1998. The results have revealed that reservoir water is classified as oligotrophic on the basis of water quality criteria. This paper also reports algal diversity. Total 19 algal taxa are reported from three classes.     

MEASUREMENT OF ENVIRONMENTAL TRADE-OFFS AND PUBLIC POLICY: A CASE STUDY1

ABSTRACT: The search for an adequate methodology to quantify environmental trade-offs led to a simulation technique, the Priority Evaluator Technique (PET). The PET was applied to determine values and trade-off preferences for environmental variables related to a proposed reservoir project. The PET simulates real world situations and allows the respondents to evaluate their preferences within a fixed cost framework. It systematically checks the respondents's perception of the existing conditions and compares the changes sought. From the responses obtained via interviewing, one can establish the extent to which respondents are satisfied with the prevailing conditions, the magnitude and direction of changes sought, the quality trade-offs, and the relative value of different situations. The PET is flexible and can accommodate alternative planning decisions, prices, incomes, and end factors. The promise shown by this application of the PET should encourage further exploration and evaluation.
