Subject: Assessing Groundwater Quality in Dong Thap Province Using Multi-variate Statistical Approach
Keywords: Cluster analysis, Coliform, Dong Thap, Groundwater, Principal component analysis
Abstract: This study aimed to assess groundwater quality in Dong Thap province of Vietnam using multivariate statistical analysis. The monitoring data were collected in April and September 2019 at 24 locations (namely GW1-GW24) with 20 parameters, namely temperature, pH, turbidity, hardness, chloride (Cl–), total dissolved solids (TDS), sulphates (SO42-), nitrates (N-NO3–), nitrite (N-NO2–), heavy metals (As, Fe, Mn, F, Pb, Cu, Zn, Cd, Hg) and microorganisms (coliform and E. coli). Groundwater quality was compared with national technical regulations on groundwater quality (QCVN 09-MT:2015/BTNMT). Principal component analysis (PCA) and cluster analysis (CA) were used to evaluate the main parameters and to group groundwater quality on similarity. The results showed that groundwater was contaminated by coliform, E. coli, Cl–, TDS and Mn2+. The remaining groundwater parameters were still within the allowable limits. PCA results showed pH, turbidity, Cl–, TDS, N-NO3–, coliform, As, Pb, Cu, Zn, Hg and Mn2+ were the main parameters affecting groundwater quality. PCA suggested that the potential sources of groundwater pollution were human and animal wastes, geohydrological characteristics of the aquifer, quality of the surface water, underground saline intrusion, industrial and agricultural activities. CA results showed that groundwater quality in the study area formed six clusters from 24 monitoring positions due to the difference in the concentrations of Cl-, TDS, Mn2+ and coliform. The results of the present study indicated that groundwater quality was not suitable for human consumption. Proper treatments are needed. Investigating specific sources of groundwater pollution and current management practices to provide sufficient scientific information for better groundwater management are urgently needed.

Subject: Reckoning Air Pollution based on Tolerance Index of Plant under Pre and Post-Covid-19 Lockdown Scenario
Keywords: Air pollution tolerance index, Pre and Post-Covid 19 lockdown period, Ascorbic acid content, Linear regression
Abstract: Air pollution is major environmental issue facing around the world. Covid-19 the pandemic which smashed all the socio-economic development of the countries also have an impact on human activities in all fields. The drastic reduction in transportation due to lockdown to control the spread of virus reduced the emission of toxic pollutants from vehicles. The air quality analysis studies indicated an increase in quality in post-covid lockdown period. Plants are always exposed to air pollution and they cope with increasing air pollution in various ways. Air pollution tolerance analyses were always performed to assess the tolerance and susceptibility of plants to air pollution. Large scale planting of tolerant plants in urban areas for creating green belts and reducing air pollution is a common practice. In the present scenario a comparative evaluation of air pollution tolerance index of plant was performed by comparing the tolerance index in pre and post-covid lockdown period. A reduction in tolerance index can be significantly correlated with reduction in air pollution after the lockdown period.

Subject: Artificial Neural Network Modelling of Traffic Noise Induced Annoyance Amongst Exposed Population
Keywords: Annoyance, Artificial neural network, Multi-layer perceptron, Mean square error, Root mean square error
Abstract: In the current situation, traffic noise and annoyance are a matter of concern. The current study aimed to predict annoyance levels using artificial neural network (ANN) multi-layer perceptron network (MLPN) by adding five parameters, such as hours of noise exposure, qualifications, marital status and age of the respondents. This study included 60 persons (30 men and 30 women). The best ANN model was chosen by comparing the mean square error and root mean square error values of 2500 different architectures (500 architectures for each neuron, that is 1-5) with constant input, output and hidden layers with varying neurons (1-5). The architecture of the best model was ‘5 inputs®1 hidden layer (5 neurons) ® 1 output’ with minimum MSE (0.014658) and RMSE (0.12107) values. The model’s performance was determined by its relative error, which was 0.198. Hours of exposure were shown to be the most important predictor of annoyance, with a score of 0.467, followed by qualification with a score of 0.418, while age was found to be the least important predictor. According to the correlation analysis, there was a high positive link between annoyance and hours, with a Pearson correlation value of 0.758, followed by qualifications, with a Pearson correlation value of 0.669.

Subject: Evaluating Water Resources Availability in Headwater Sub-catchments of Subarnarekha River Basin in a changing Environment using Remote Sensing and GIS Software
Keywords: Environment change, Delta change, Pitman model, Subarnarekha river basin, Rural livelihoods, Remote sensing, GIS
Abstract: The Subarnarekha river basin, which is predominantly rural, is a river shared between Jharkhand, West Bengal and Odisha. The Jharkhand communities along the river largely depend on the availability of stream flow for their livelihoods which are now being threatened by the effects of a changing environment. The study assessed the effects of climate change on water resource availability in 7 selected headwater sub-catchments of the Subarnarekha river basin using the Pitman hydrological model. The model was driven by 10 statistically downscaled climate models forced with representative concentration pathway (RCP 3.5 and RCP 7.5) for the near 2021–2050 and far 2050–2080 futures. The results of water resource availability varied, depending on whether the short- or long-term scenarios were modelled. 60% of the sub-catchments predicted an increase in stream flow for the near and far-future under the RCP 3.5 emission scenario. Under the RCP 7.5 scenario, a decrease in stream flow was simulated for all sub-catchments with the decrease ranging from -4.07% to -61.59%. The reduction in water resources would be more significant in the drier parts of the basin than in the wetter parts, which are projected to maintain approximately 80% of current stream flow levels. The present study evaluates the geomorphic process of upper watershed of river Subarnarekha in the state of Jharkhand, India. Various spatial information is extracted with the help of remote sensing and GIS techniques, which provided an understanding of precise scenarios related to basin development.

Subject: Rainwater Harvesting Structures at Industrial Location in Coastal Area of Mumbai
Keywords: Rainwater harvesting, Groundwater quality, Coastal area, Oil refineries
Abstract: The coastal zone is the most industrialized and urbanized area in the country. Most coastal areas in the world are dependent on local fresh groundwater resources. Most of the oil refineries and industries are situated in coastal areas and often cause soil and groundwater pollution, due to potential leakages of petroleum products. The Mumbai refinery is one of the largest refineries situated in coastal areas. The annual freshwater consumption at Mumbai refinery for various process and non-process requirements is approx. 35 lakh kL. The deficit of water is outsourced and carted to refinery through water tanker. To overcome the difficulties of outsourcing the water the potential of rainwater harvesting from rooftop of structures has been calculated by considering the present groundwater quality status. A total of 38 locations were identified having rainwater harvesting potential from rooftop of existing structures within study area. The total quantity of potential rainwater harvesting was calculated as 1.45275 lakh kL. This potential of rainwater harvesting from existing structures will mitigate the outsourcing of water and will also improve the groundwater recharge and quality of groundwater.

Subject: The Fake Forests of Chhattisgarh
Keywords: Forest area, Forest destruction, Tribal, NTFP, Livelihood, Chhattisgarh, Data fudging
Abstract: Chhattisgarh, the 10th largest state of India, is famous for its forests and tribal population. The forest area as a percentage of the state’s total area as per the latest economic survey of the state stands at 44.2%, much higher than the all-India level of 21.67%. The total tribal population of the state represents more than 10% of entire India and accounts for more than 30% of the state’s population. The tribal population of the state is immensely dependent on the forests for their livelihood. The forest is their dwelling and a vital income source considering the non-timber forest produce collected by the tribal women. The forest also provides them firewood, medicinal plants, mahua, etc., for their captive use. In this background, proper measurement of the forest area across the state becomes immensely important. However, consideration of economic surveys of the state from 2007-08 to 2020-21 raises some doubt regarding the authenticity of the state’s forest area data. The present paper leads an investigative approach backed by solid literature review and quantitative comparison to determine whether the forest area data is fudged or accurate. The result refutes forest area related economic survey data of Chhattisgarh as accurate.

Keywords: Electro-coagulation, Optical density, Biochar, Current density, Characterization, Adsorbent dosage
Abstract: In this study, dye effluent was treated by electro-coagulation method using aluminium (Al) electrodes along with biochar (adsorbent) by varying conditions, like pH, current density, operating time and adsorbent dosage. Biochar obtained from wood waste was powered and sieved through 600 mm sieve. Characterization of biochar was done by scanning electron microscopy, energy dispersive analysis of x-rays, surface area analysis and proximate analysis. Characterization of dye effluent for parameters, like pH, total solids, total suspended solids, dissolved oxygen, biological oxygen demand, chemical oxygen demand, electrical conductivity and total organic carbon. Optical density of dye effluent was found using ELISA microplate reader. It was observed that with an increase in current density and contact time, removal efficiency also increases. Only for Al-Al electrode, higher removal efficiency of 76.71% was obtained at optimum pH 10, current density of 60 A/m2 and at a contact time of 60 min. It was also observed that as the adsorbent dosage increases, removal efficiency also increases. As dosage of 1 g was added along with the optimum conditions for Al-Al electrode, removal efficiency increases to 88.27%. Therefore, by adding biochar as adsorbent, efficiency is increased by 15% approximately.

Keywords: Plastic bags waste, Plastic bag waste management, Recycling, Landfill, Incineration, Africa
Abstract: Plastic bag waste is a major health and environmental issue faced by African countries across the economic development spectrum. In response, African nations have adopted waste management technologies to minimise health and environmental problems related to plastic bag litter. The extent of this problem has put pressure on municipalities to provide sustainable and effective plastic bag waste management systems. This current paper reviews the existing technological and infrastructural plastic bag waste management approaches in African countries since 2010. Data sources comprised dissertations, peer-reviewed journal articles and websites. The databases included Elsevier, institutional repository and Google Scholar. The current paper argues that African countries lack properly designed and adequate technology and infrastructure for plastic bag waste management due to constricted waste management budgets. In light of these findings, the paper proposed the adoption of the circular economy and for African municipalities to invest in income generating projects, like recycling projects that can help purchase technological and infrastructural resources.

Subject: Pollution of pH in groundwater due to underground tunnel using GIS analysis
Keywords: Spatial analysis, GIS, Groundwater, pH, Water quality, Underground
Abstract: This paper makes an attempt to find the impact of the construction of underground metro rail corridor on the water quality parameter pH below the ground surface. This massive construction which is constructed very deep from the ground surface tries to alter the properties of groundwater regime and the chances of polluting the water are very high. The water quality parameters which are naturally available below ground surface also get altered. This paper discusses about the impact on water quality parameter pH due to the construction of underground metro rail corridor and its pollution level in the groundwater. The water quality data collected are divided into before, during and after the construction of corridors. Spatial analysis using GIS is carried out to predict the changes in three phases. The pollution of pH seems to be more than 7.5 after tunnel construction when compared to undisturbed soil surface.

Subject: Climate-Smart Livelihood – A Case Study of Dodaballapura Taluk of Bangalore Rural District
Keywords: Agriculture, Climate change, Climate smart livelihood, Climate smart agriculture
Abstract: More than a billion farmers around the world are on the frontier of climate change. These farmers’ livelihoods are directly and indirectly affected by the impact of climate change. Climate smart livelihood explains the practices in agriculture sector which sustainably contributes to productivity and income. This study tries to explore the adaptation of climate smart livelihood techniques by the farmers in the Doddaballapur taluk of Bangalore rural district. The data was collected primarily from the five villages and 50 households of Doddaballapur taluk. The survey revealed that 81.67% of the respondents faced problems during adaptation of climate smart agriculture was due to poor support of local and national authorities with climate related issues and ranked it one of the major constraints. This was followed by lack of financial constraints, lack of knowledge about adaptive practices (78.50%), non-availability of agriculture inputs in time (76.17%), lack of education about the adaptation strategies (75.33%), unavailability of new technologies (78.83%), higher cost of the agricultural inputs used for the practices (71.17%), lack of improved communication facility about the climate change (71%), migration of youth due to urbanization and better employment (70.83%), lack of knowledge about post-harvest technology (68.83%), lack of awareness about climate change issues (59.83 %). The study reveals that as most farmers believe they have low capacity to adapt to climate-smart agriculture due to lack of availability of resources, Government can help farmers through National Agricultural Extension Project (NAEP), Krishi Prashasthi, etc.

Subject: Phycoprospecting of Some Indigenous Algae for Improvement of Dairy Wastewater Quality
Keywords: Algae, Oscillatoria spp., Dairy, Wastewater
Abstract: Algae are vast multifunctional photosynthetic aquatic organisms. the present study aim to investigate application of Oscillatoria spp. for improvement of physico-chemical parameters of dairy wastewater. The results showed to reduce nutrient concentrations from dairy wastewater, such as pH, alkalinity, hardness, TSS, TDS, TS, BOD, COD, oil and grease, by more than 50% alongwith improvement of treatment process by reducing CFU of bacteria present. The ability of Oscillatoria spp. to remove alkalinity was about 80% and for hardness it was more than 50%. Isolated algae not only is prominent in treatment of wastewater but also has potential antioxidants, like catalase and peroxidase along with phenols (90 mg/mL), carbohydrates (100 µg/mL) and protein (180 µg/mL), as great reservoir of nutrients. Oscillatoria spp. can act effectively towards control of water pollution.
