Sangita Agarwal, Kakoli Banerjee, Nabonita Pal, Kapileswar Mallik, Gobinda Bal, Prosenjit Pramanick and Abhijit Mitra,[DOI: 10.24214/jecet.A.7.1.01629.]

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.

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

Sateesh N. Hosamane, G. P. Desai,[DOI: 10.24214/jecet.A.7.1.03039.]

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.

Basavarajappa H.T, K.N and Manjunatha M.C,[DOI: 10.24214/jecet.A.7.1.04053.]

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.

N’guessan Yao Alexis, Diangoné Eric, Konan Konan Ernest, Sékongo René, Wognin Valérie.[DOI: 10.24214/jecet.A.7.1.07079.]

Of all the ills that undermine our environment, coastal erosion deserves special consideration on our part. The Ivorian coastline and in particular the coastline of the Vridi Canal at the Port-Bouët Lighthouse is not immune to this phenomenon. This study places particular emphasis on the issue of updating the data of the evolutionary trend of the Vridi-Port-Bouët perimeter because of the dynamism of the area, by the joint analysis of the morphological characteristics of the beach and the dynamics of the area next to. Examination of superficial facies and sub-surfaces has shown that these granulometric facies can be a witness of coastal erosion. Thus, 36 sediment samples from three sampling sites (Capko, Bidet and Phare) showed that the sands of this area are very coarse to coarse, well classified with a variable Skewness. They present a variation of the grain size of the surface (00 cm) towards the depth (200 cm) testifying to the evolution of the coastline.

Local Ecological Knowledge (LEK) Surveys to find the spatial distribution of Malabar Pied Hornbill (Anthracoceros coronatus) and their familiarity in the Western Ghats region of Karnataka

Shrinivas K.R. and Vijaya Kumara,[DOI: 10.24214/jecet.A.7.1. 09702]

Malabar Pied hornbill (MPH) being one of the flagship species in the Western Ghats is considered as Near Threatened (NT) and the population is in decreasing trend according to the IUCN Redlist Data. Local Ecological Knowledge (LEK) surveys were conducted in the Western Ghats region of Karnataka state mainly to know the basic knowledge of Hornbill and their co-existence. The questionnaire also aimed to account for the presence and absence of Hornbill species. MPHs are found sparsely in these areas but the Malabar Grey hornbill was in prevalent in all areas. Out of 726 interviews and interactions been made during July 2014 to June 2017, more than 75% of the respondents were farmers or farm labors, nearly 22% were forest personnel and remaining were either business men or resource persons like school masters, postmen, etc. People who knew the unique breeding behavior of hornbills never entertained or encouraged hunting. During the LEK survey an attemp was made to bring about the conservation issues with the people. MPHs were well distributed in the areas with riverine conditions and desirable altitude holding favourable conditions. Forest fires and predation has been the main reason for their population decline according to the resources. The roosting sites have shown considerable decline in the population of the hornbills and also the roosting place has been kept on changing due to many anthropogenic threats. An immediate action like capacity building is required to control the declining population

Soil Organic Carbon (SOC) regulation by anthropogenic activities and natural factors

Pritam Mukherjee, Madhumita Roy and Abhijit Mitra,[DOI: 10.24214/jecet.A.7.1.10310]

The present study has illustrated the estimation of the Soil Organic Carbon (SOC) distribution keeping in view the variation of environment. Hence two significantly contrasting environments were selected to evaluate the role of anthropogenic/natural factors on the SOC budget. The regions selected as experimental beds for the present study are highly urbanized city of Kolkata and natural mangrove ecosystem of Sundarbans. 6 stations in each of these two regions were selected during January 2018. We observed relatively higher value of SOC at Kolkata (mean value = 1.95%) compared to mangrove dominated Indian Sundarbans (mean value = 1.37%). The relatively higher values in the city soil may be due to the impact of domestic and municipal waste generation and dumping by the heavily crowded population of the city. The lower value of SOC in Sundarbans may be attributed to the tidal washing of the top soil at regular intervals of time. Erosion of embankments is also a cause of low SOC value in Sundarban region.

Srujan.K, Venkateshwarlu.Ch, Ramu Tharla, V.Vasu, V.Saidulu, M. Ramu [DOI: 10.24214/jecet.A.7.1.11121.]

Due to rapid industrialization and overexploitation of the groundwater resources, there is a drastic change taking place in the Hyderabad urban environment.  The present study area is categorized into 1.Tannaries of Bholakpur area, 2. Pharmaceutical industries at VST Vidyasagar, 3. Domestic an industrial sewage in Musi River at Nallachervu, Pirzadiguda, Uppal area of Hyderabad, Andhra Pradesh, India. The possible quality of the heavy metals major and trace elements in the hydrological system have been identified and quantified in the present study. Depending on the environmental parameters, the trace metals and associated elements may form complexes and precipitate or become concentrated at several places. In the present study is an attempt made to evaluate the changes in the water quality of the Hyderabad urban environment. All trace elements, which include As, Se, B, V, Fe, Co, Pb, Cu, Zn, Cd, Mn, Ni, Mo, and Ba, and Na, Mg, Si, Ca, Al, were analysed using the highly sensitive inductively coupled plasma-mass spectrometer (ICP-MS).  For most of the elements, the detection limits are around 1 ppb. Analytical data were processed with various computer programs for statistical evaluation.  The impacts of natural and anthropogenic sources on the elemental concentration and the total area affected by each element have been deciphered using these graphs. The range and average concentrations of some of the trace elements of environmental concern in the groundwater. Most of the trace elements show high concentrations (several orders of magnitude) in the groundwater of Hyderabad in comparison to global average standards. Especially salts like Na, Ca, Mg, Se, are at peak levels and add turbidity to water and make it worst
