Subject: Adaptation and Livelihood Resilience by Rainfed Farmers to Climate Variability in Food Storage Areas in Bengkulu Province, Indonesia
Keywords: Climate variability, Rainfed farmer, Adaptation, Livelihood resilience
Abstract: Climate variability causes changes in the amount of rainfall and rainfall patterns that affect the lives of rainfed farmers. Farmers are not only synonymous with poverty but also because of the great uncertainty over the impacts and the magnitude of climate variability. The objectives of this study were : to determine the use of adaptation of climate variability by farmers, to measure the resilience of farmers‘ livelihoods related to climate variability and to determine the factors related to the livelihood resilience of farmers. A survey by interviewing purposively selected 100 farmers was conducted in food storage areas in Bengkulu Province from September to November 2020. The results showed that the use of adaptation by farmers was still low and tended to choose the use of climate variability adaptation that did not require additional expenditure, namely shifting the planting season. The livelihood resilience of farmers in dealing with climate variability is also in the low category due to the low institutional function and participation of farmer groups. The use of adaptation is negatively related to livelihood resilience. Poverty and limited resources are reasons for farmers to prefer adjusting conditions to nature in order to increase livelihood resilience in dealing with climate variability.

Subject: Heavy Metal Bioaccumulation and Air Pollution Tolerance Index of Selected Plant Species from Urban Area
Keywords: Ascorbic acid, Chlorophyll content, Metal accumulation index, Relative water content
Abstract: The study was conducted to evaluate metal accumulation index and air pollution tolerance index of five selected plant species, namely Buddleja asiatca, Ficus religiosa, Leucoseptrum canum, Nyctanthes arbor-tristis and Tecoma stans along roadside of Lalitpur district. The air pollution tolerance index (APTI) was calculated based on various biochemical parameters, namely total chlorophyll, leaf extract pH, ascorbic acid and relative water content. Total chlorophyll contents and leaf extract pH of leaves were affected adversely by dust pollution. These parameters of leaves seemed to decreased with increasing pollution levels. Ascorbic acid and relative water content of leaf samples were increased with increasing pollution levels to withstand stress caused by pollution. The plants varied in their metal accumulation and air pollution tolerance. Metal accumulation in plant species was higher in heavily polluted sites. According to average metal accumulation indices (MAIs), the studied plants was found in descending order Ficus religiosa (12.98) >Nyctanthes arbor-tristis (5.84) >Lecosceptrum canum (5.10) >T. stans (4.0) >B. asiatica (3.95) in leaf samples; while in bark samples MAI values were in order Ficus religiosa (38.69)>Lecosceptrum canum (16.18)>Buddleja asiatica (14.16)>Tecoma stans (7.45)>Nycatanthes arbor-tristis (6.33). The mean values of APTI within the city of Lalitpur district were as follows: B. asiatica (6.24); L. canum (8.32); N. arbor-tristis (8.46); T. stans (8.87) and F. religiosa (10.44). The study indicated relatively high metal accumulation and tolerance of Ficus religiosa emerged as the tolerant species with high MAI and APTI value. Hence, Ficus religiosa can be suggested for plantations along the roadside of urban areas for green belt development.

Keywords: Physical, Bacteriological, Chemical, Groundwater, Investigation
Abstract: Shillong city is ever-expanding in all directions leading to population increase and increased utilization of the natural resources, especially the water resource available. To meet the daily requirement of water for domestic as well as commercial demand, the people of Shillong city are increasingly turning their attention to the underground aquifers. However, the water, that is being pumped out is many times being utilized without proper knowledge of its physico-chemical and bacteriological properties. Ignorant on this matter will put the user in a situation where his health may be compromised. This work was initiated with the sole purpose to understand the baseline concentration of different physical, chemical and bacteriological parameters of the groundwater available in and around Shillong city. Thirty-five (35) sampling locations were identified and sampled for three different seasons (winter, pre-monsoon and post-monsoon). The significant observation in this study is that there is a spatial and seasonal variation of all the parameters selected. Concerning pH, iron and total coliform, the majority of the samples reported values that are higher than the prescribed limit for drinking water.

Keywords: Pesticides, Adsorption, Malathion, Isotherms
Abstract: Extensive loads of pesticides are utilized to increase the crop productivity in modern agricultural practices. Slow degradation of pesticides into the environment and extensive or inappropriate use by farmers can lead to contamination of water, soil, air, several types of crops and in turn human beings. Malathion pesticide has been widely used as fumigant, in agriculture and in residential landscapes to replace more toxic organochlorine pesticides, even otherwise result in a serious setback to human health causing skin and nervous defects. Adsorption technique is one of the most intensively availed and reliable method adopted due to its ease of operation, non-energy intensive and high removal competence of organic pollutants, like pesticides. Delonix regia pod shells (DRPS), an eco-based material is employed to chelate malathion from aqueous media through batch mode under varying operational factors, namely, pH (3-11), initial malathion concentration (50-300 mg/L), DRPS dosage (50-250 mg), contact time (10-60 min) and temperature (293-333 K). Optical microscope, FTIR, SEM are utilized to characterize the selected sorbent’s nature. Isothermal data fitted well with the Langmuir plot in preference to Freundlich plot. From the observations made, DRPS is found to be a promising ecofriendly, economically viable material for the sequestration of malathion.

Keywords: Desalination plants, UAE, Integrated waste management, issues, prospects
Abstract: There are more than 199 desalination plants that are located in different regions, such as the United Arab Emirates, Saudi Arabia, Kuwait, Qatar, Bahrain, Egypt and other countries. The desalination plants that are located in UAE accounted for 35% of water generation in the year 2013 and are the main source of drinking water in the country. Desalination plants carry out activities that are associated with the cleaning and purification of water that has been collected from the sea. By using several filtering and purification processes, the desalination plants make seawater fit for drinking and help in meeting the water demand of the individuals. The present study aims to understand the performance of desalination plants in the UAE and outline the way forward to overcome the prevailing challenges. To reach the major objectives, a quantitative research approach has been implemented using quantitative data. Structured questionnaires have been used as primary data which is close-ended in nature. A simple random sampling method had been used for the selection of candidates suitable for the study. The sample unit mainly consisted of 150 specialists who are involved in the process of desalination in the UAE. Statistical tools, such as Chi-square and SPSS methods had been adopted for the analysis of the collected data and to acquire accurate results. Further, findings and discussions have been evolved using statistical tools. Limitations and future aspects are also implemented.

Keywords: Karanj fruit shell, Activated charcoal, Cationic dyes, Isotherm models, Adsorption
Abstract: In the present study, removal of water-soluble cationic dyes under static conditions was studied using non-toxic, low-cost and energy-efficient Karanj fruit shell activated charcoal (KFS-AC). The study reveals that removal of upto 90% of dye (methylene blue and malachite green) on KFS-AC without agitation at room temperature was observed. The effect of various parameters, such as pH, volume of dye, contact time and adsorbent dosage was investigated. The KFS-AC showed a wide pH range of adsorption with highest adsorption at pH 11.3. The adsorption properties of activated charcoal were studied using equilibrium isotherm models (Langmuir and Freundlich). The Langmuir model yields a much better fit than Freundlich model for both dyes having high regression values. The results revealed that energy-efficient activated charcoal prepared from Karanj fruit shell is highly effective in the removal of Methylene Blue and Malachite Green dyes from their aqueous solutions and can be used as a reliable alternative to high-cost commercial adsorbents.

Keywords: Environmental pollution, Solid waste, Soil, Landfill, Dumpsite, Alkalinity, Heavy metals, Monitoring, Sudan
Abstract: Environmental pollution generated from uncontrolled dumping is a major problem in Sudan due to the lack of a proper waste management system. This study was conducted in Wadafiea dumpsite, Khartoum north, Sudan to determine the physico-chemical parameters and heavy metals concentration in some selected soil samples. This study aimed to assess the risk of heavy metals pollution on physico-chemical properties of soils around the dumpsite and to compare the seasonal variations in concentrations of heavy metals on physico-chemical parameters. The level of pH, CaCO3, EC and heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in soils around dumpsite were determined using pH meter, conductivity meter and atomic absorption spectrophotometer method (AAS). Ten samples of soils were collected in dry and rainy seasons from different directions around the dumpsite of solid waste. The obtained results of the soil samples’ analysis showed that alkalinity in the soil of the landfill and around the dumpsite has slightly increased. The concentrations of pH in the dry season were higher than the levels of pH in the rainy season. The heavy metals concentrations in the soil samples in the dry and rainy seasons varied per sample of sampling location and seasons. These findings indicated that the concentration values of heavy metals in the rainy season were higher than in the dry season. The values of all the heavy metals analyzed for samples from the dumpsite and the area adjacent to the landfill were higher than those from the control site suggesting possible mobility of heavy metals from dumpsite to the farmlands through leaching and runoffs, but they were below the values recommended by the World Health Organization and Canadian guideline values.

Abstract: The increase in imperviousness of land and a decrease in infiltration due to urbanization causes ample amount of surface runoff, which has become a serious problem in unplanned cities. The rainfall intensity-duration-frequency (IDF) relationship is one of the most commonly used tools for urban stormwater modelling. In the present paper, estimation of design rainfall intensity based on intensity–duration–frequency (IDF) curves for Ranchi city was made. IDF curves for short duration rainfall (5 min, 15 min, 30 min, 1 hr, 2 hr, 6 hr, 12 hr and 24 hr) were plotted with the return period of 2, 5, 10, 25, 50, and 100 years. Extreme value type I (EVI) gumbel distribution was used to find design storms for various return periods. The results obtained presented that the correlation coefficient is very high representing goodness of fit of the formulae to estimate IDF curves in the region of interest.

Subject: Recovery of Hexavalent Chromium from Metal Finishing Wastewaters using Electrochemical Ion Exchange
Keywords: Metal finishing effluents, Cr(VI) ions, Ion exchange, electrochemical ion exchange, ion-permeable membranes
Abstract: This investigation aims at the removal and reclamation of hexavalent chromium from metal finishing industrial wastewater by an advanced ion exchange process, namely electrochemical ion exchange (EIX). An electrochemical ion exchange reactor of desired dimensions was fabricated with the help of ion-permeable membranes, stainless steel cathode and RuO2 coated Ti expanded mesh anode. The performance of the reactor was studied in batch recirculation mode, continuous flow mode at different experimental conditions. The influence of various experimental parameters, such as initial concentration of the test solution (20, 300, 1000 mg/L of Cr (VI)), applied voltages (2.5V, 5V, 7.5V, 10V) and flow rates of the process stream (2, 4, 6, 8, 10, 12 and 14 mL/min) on removal/reclamation efficiency was also studied. The results obtained were compared with the electrodialys is process conducted at the same optimal conditions. It was found that the EIX process with three compartments has more removal efficiency at optimum experimental conditions than the electrodialysis process. The continuous flow process of the reactor with 300 mg/L of Cr(VI) as inlet concentration has been studied to predict the breakeven point of the reactor. It was noted, the presence of Cr(VI) in the treated wastewater is almost zero up- to the discharge of 19 L of treated rinse water.

Subject: Valuation of Environmental Damage in National Income Accounts for India: Green Gdp
Keywords: Green national accounts, Green gross domestic product, Green economy, Carbon dioxide damage, Green accounting
Abstract: The paper introduces a new methodology of national accounts as compared to the conventional national income accounting technique used in India. The gross domestic product (GDP) of a country does not measure the intensity of environmental degradation caused as a result of the production activities in the country. This study attempts to create a structure for the green GDP calculation in India. It has been calculated for the period 1990-2018, taking into account variables that have huge ecological footprints, such as carbon dioxide emission, particulate emission, natural resources depletion and waste generation. These variables have been aggregated in monetary terms and thus reduced from the GDP values, also giving the proportion of environmental degradation in the economy. Data for a few variables are scarcely available, though the use of proxy variables leads to a well-established structure to calculate green GDP for India.

Subject: Assessment of Metals Contamination in Soil from an Integrated Waste Transfer Station
Keywords: metals, integrated waste transfer station, soil contamination, leachate
Abstract: The concentration of some metals (Pb, Cu, Ni and Cr) in the soil samples underneath a municipal integrated solid waste transfer station site was investigated. The transfer station receives approximately 14 m3 of partially sorted domestic solid waste every day. The soil samples are collected from three locations surrounding the transfer station in various depths (2, 4, 6, 8 and 10 m). The obtained samples were destructed and analyzed to determine metals concentration. It is found that the concentration of Cu in the soil fluctuates from 0.22-3.99 mg/kg, the concentration of Cr is 115-119.2 mg/kg, the concentration of Ni is ranged from 0.73-3.55 mg/kg and the concentration of Pb is 2.85-3.59 mg/kg. Cr has the highest concentration among all of the metals in each sampling point. The concentration of metals decreases following the depth of the soil. In contrast, the metal of the same depth in every sampling point only has a relatively similar concentration. Hence, the depth of the soil does not significantly affect the concentration of metals. This phenomenon is probably due to the soil characteristics and permeability directly influences the concentration of metals in the soil.

Subject: Environmental Impact of Shrimp Pond Effluents on Water Quality and Phytoplankton Biomass in a Tropical Mangrove Estuary
Keywords: Brackishwater, aquaculture, Effluents, Farming periods, Nutrients, Phytoplankton, Water quality
Abstract: Water quality and phytoplankton biomass were examined over one year period concerning aquaculture farming periods in a river-dominated, mangrove estuary receiving periodic inputs of effluents at outfall of shrimp farms (OFSF) stations from adjacent brackishwater shrimp ponds and in away from shrimp farms (AFSF) stations. Salinity, dissolved oxygen (DO) and total suspended solids (TSS) at the OFSF stations were significantly different (p<0.01) from AFSF stations. There were no significant differences between the OFSF and AFSF stations in dissolved nutrient concentrations. Water quality and phytoplankton biomass in OFSF stations were within the ambient levels, based on comparison with AFSF stations. Regular river discharge and tides of semi-diurnal type cause water quality and phytoplankton biomass in the OFSF stations of lower and middle reaches of estuary returned to levels equivalent to those in the AFSF stations. The limited spatial and temporal impact suggests that the effluents were dissipated by tides and assimilated and/or mineralized by the estuarine food web. Our results imply that river-dominated, mangrove estuary has some capacity, atleast over short spatial and temporal scales, to process intermittent inputs of pond-derived effluents.
