An Environmental Impact Assessment of Sewage Pollution in Madurai District

An Environmental Impact Assessment of Sewage Pollution in Madurai District



J.S.Amarnath, U. Sridevi



The study was conducted in Madurai district of Tamil
Nadu to study the Environmental Impact Assessment of sewage pollution.
The study revealed that the decline in crop production was directly
related with the pollution intensity. The averting or defensive
expenditure for drinking water and irrigation water included obtaining
protected water, getting water from non-polluted areas, boiling the
water and purchase of water filters. The agricultural damage function
related the value of agricultural damages to averting expenditure of
land and irrigation water and quality indices of land and water
quality.Contingent valuation study revealed that the proportion of
farmers WTP was higher in seriously affected category with 85.71 per
cent study area and in low affected category, it was 28.57 per centwhich
revealed that the willingness to pay varied according to pollution
intensity. The amount of WTP was also higher for seriously affected
farmers with Rs.1800 per year each in study area which was due to higher
pollution intensity prevailing in these farms. Seriously affected
farmers were interested and willing to pay whatever they were able to
pay which might be due to high pollution prevailed in that category. The
proportion of compensation was lower in seriously affected farms since
the farmers in this category felt that the compensation principle would
not be practical and time consuming. In seriously affected farms,
household size and drinking water quality had positive influence on WTP.
Age and Green index had negative influence on WTP. In low affected
farms, household head’s education, household size and occupation dummy
had positive relationship with the willingness to pay while green index
had negative influence on WTP.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
