Abstract

Land embraces all reasonable stable or predictably cyclic, attribute of the biosphere including the atmosphere, soil and underlying geology. Mapping of Land Use/ Land Cover (LU/LC) is essential for planning and development of land and water resources of engineering projects under progress. An attempt have been made to delineate the level-I, level-II and level-III LU/LC classification system through NRSC guidelines (1995) using both Digital Image Processing (DIP) and Visual Image Interpretation Techniques (VIIT) through GIS software’s. Efforts have been made to classify the LU/LC patterns using False Color Composite (FCC) data of IRS-1D PAN+LISS-III (Band: 2, 3, 4) through ERDAS Imagine v2011 and ArcGIS v10. The classification accuracy is found to be more in case of digital technique as compared to that of visual technique in terms of area statistics. Remote Sensing (RS) satellite data with its synoptic view and multispectral data provides essential information in proper planning of LU/LC conditions of the larger areas. The final results highlight the potentiality of geoinformatics in LU/LC classification in Yelanduru taluk, Karnataka, in natural resource mapping and its management.

Assessment of Air Quality Data using Meteorological Parameters at Belagavi City, ndia

Sateesh N. Hosamane, G. P. Desai,JECET; December 2017- February 2018; Sec. A; Vol.7. No.1, 030-039.[DOI: 10.24214/jecet.A.7.1.03039.]

Abstract

Particulate matter (PM) smaller than about 10 micrometres (PM10), have received more attention, due to its capability to settle in the respiratory system and lungs and cause health problems. Studies have indicated that the levels and distribution of air pollution are highly dependent on the meteorology. The study was conducted based on this theory and it aims to determine the variation of fine particulate matter (PM10) with selected meteorological variables over selected locations of Belagavi city for the period of January 2012 to December 2013. The statistical analysis was used to compare air pollution data with National Ambient Air Quality Standards (NAAQS). Simple regression and multiple regression techniques were used to model PM10 concentrations and distribution as a function of meteorological factors such as temperature (T), wind speed (WS), relative humidity (H) and rainfall (R) was investigated. The results reveal that there is a moderate correlation between the air pollutant concentrations and the meteorological factors in Belagavi city.

Sangita Agarwal, Kakoli Banerjee, Nabonita Pal, Kapileswar Mallik, Gobinda Bal, Prosenjit Pramanick and Abhijit Mitra,,JECET; December 2017- February 2018; Sec. A; Vol.7. No.1, 016-029.[DOI: 10.24214/jecet.A.7.1.01629.]

Abstract

We conducted a survey on the true mangrove floral stem biomass and stem carbon during July 2012 and July 2017 with the aim to estimate the rate of stored carbon per hectare (carbon sequestration) in the Mahanadi delta complex of Odisha. A total of 26 species were documented from the region out of which Heritiera fomes showed the highest population density (31.12 No./m2 in 2012 and 28.81 No./m2 in 2017). Considering the total stem biomass of all the 26 true mangrove floral species, the rate of change of biomass was observed to be 16.20 tha-1y-1, which represents carbon sequestration of 7.34 tha-1y-1. This sequestration value generates a CO2-equivalent of 26.94 tha-1y-1, which calls for the conservation and restoration of mangrove stands of Mahanadi delta region to minimize CO2 level at local scale.

Vegetation Analysis of Southern Moist Mixed Deciduous Forest of Ittiyani, thirappally, Thrissur, Kerala

Sreepriya Nathan V. and M.A.Suraj,JECET; December 2017- February 2018; Sec. A; Vol.7. No.1, 001-015,[DOI: 10.24214/jecet.A.7.1.00115.]

Abstract

Floristic and phytosociological studies were carried out in the Ittiyani forest of Athirappally range, under Vazhachal Forest Division during the months of January, February and March 2017. The area is rich in biodiversity. The forest type of the study area as per Champion and Seth’s classification is Southern moist mixed deciduous forest. The area is under severe threat due to proposed hydroelectric project and anthropogenic activities. Floristic studies revealed the presence of about 83 species of plants belonging to 39 families in the study area out of which 30 (36.14%) are trees, 24 (28.91%) are climbers, 17 (20.48%) are shrubs, and 12 (14.45%) are herbs. Xylia xylocarpa is the most dominant species. The total tree density is 630 no/ha. The Simpson’s Index Value is 0.1710 and the Shannon Index Value is 2.38. Phytogeographical analysis indicates that Indo-Malesian elements are dominant

Impact of Industrialisation and Urbanisation on Algal Growth in the South Zone of Kanpur City

Abhilasha Srivastava, JECET; September 2017- November 2017; Sec. A; Vol.6. No.4, 548-553.,[DOI: 10.24214/jecet.A.6.4.54853.]

Abstract

The present study deals with the distribution of blue-green algae in paddy fields which were present in the South zone of Kanpur city and their disappearance with urbanization and industrialization of that area. For the last three decades the area of South Kanpur has been subjected to tremendous stress of urbanization and industrialization. Before that the area was well known and popular for rich growth of paddy crop because of water-logged conditions, which support paddy cultivation. But today the developmental factors have pushed the natural habitat towards the periphery. The urban land is still intercepted by puddles, pools, canals and in some places, permanent or temporary water reservoirs as found before urbanization and industrialization. In these fields, algae play the important role of asymbiotic N2- fixation. Besides this, they cause purification and oxygenation of H2O and form a biological film to maintain water quality. Some algae secrete organic substances and cause turbidity and colouring of H2O, some cause allergic reactions and lethal diseases in human beings and cattle, creating serious health problems. Stresses caused by industries, civil and agricultural waste affect the water quality and algal community adversely, but response of algae to various physico-chemical attributes make them useful as biomonitors. These biomonitors are the de best indicators of water quality which had been changed due to urbanization and industrialization hence they exhibit cumulative response to a wide spectrum of environmental factors. So this study deals with the role of algae in biology, self purification, pollution of waters and its exploitation for use as tools for environmental up gradation.
