Subject: When nature decides who stays and who goes: Priority effects extirpating the non-native brown trout Salmo trutta fario L. Population from a Himalayan river
Keywords: Nature, non-native brown trout Salmo trutta, Population from a Himalayan river
Abstract: Climate-induced stochastic events bring forth idiosyncratic changes in habitat and community assemblage patterns of an area. Nature governs its priorities in such incidents, where native taxa are preferred over the invasive ‘late-comers’, thus leading to extirpation of the latter, according to the concept of ‘priority effects. This stronghold of nature strictly comes into play when an ecosystem is least altered from its natural state. River Asiganga in Uttarakhand, India was chosen as a case study to understand this theory, where cloudburst –induced flash floods are considered to be a reason for the complete wipe-out o non-native brown trout (Salmo trutta fario), leaving behind the native snow trout (Schizothorax species).

Subject: Addressing poverty in India’s Revised National Tuberculosis Control Programme
Keywords: Addressing poverty in India, Revised National Tuberculosis Control Programme
Abstract: The bi-directional relationship between poverty and tuberculosis (TB) is well established. Poverty aggravates material disadvantage, social exclusion, discrimination in participation across a wide range of socio-economic and behavioural activities along with undernutrition, overcrowding, lack of accesss to health-care and other social determinants of health; it also exacerbates TB and its spread. India being a high TB burden and lower-middle income country accounted for 27% of the world’s 10.4 million new disease cases in 2017.Nearly 27.5% of India’s population is multi-dimensionally poor and deprived in at least one third of the ten weighted indicators of health, nutrition and living standards components of Multi-Dimensional Poverty Index (MPI) and 196 million people living in acute MDP in four states (Bihar, Jharkhand, Uttar Pradesh and Madhya Pradesh) alone in the country.

Abstract: Understanding plant compositional patterns over long timescales has greatly improved for long timescales has greatly improved the foundations of community ecology. Data from long-term forest monitoring sites form the core of community ecology research, and a global network of several such sites continue to generate valuable data on global change. India also has such long-term ecological research programmes operating since many decades. Despite the overall increase in such long-term networks, the world’s urban landscapes are not adequately represented compared to their forested counterparts. As a prominent example of this bias, out of the 24 Long Term Ecological Research (LTER) sites established till 2003 in the United States, only to focus on urban landscapes.

Subject: Urban waste recycling in developing countries should be improved
Keywords: Urban waste recycling, Developing countries, improved
Abstract: Currently, the major ecological concern in developing countries (e.g Mexico, Indian, China) is the poor control of urban waste (highlighted by epidemics of rubbish dumps).This is leading to unsustainable use/depleting of the Earth’s limited natural resources and the global pollution of life-supporting hydrosphere, atmosphere, lithosphere and biosphere (particularly by phosphorus and nitrogen from food waste and hazardous chemicals from electronic and plastic waste) due to water/air streams and interrelated biogeochemical cycles. At present, the major part of all urban solid waste (USW) in developing countries goes to landfills, incineration and illegal dumps that is unsustainable and risky for both human health and the global natural environment (e.g. climate change through methane (CH4) and carbon dioxide (CO2) emissions).Only a small part of USW in developing countries is recycled.

Subject: A simple push-pull strategy to harvest earthworms from coconut leaf vermicompost produced in tanks
Keywords: Coconut leaf vermicompost, cow dung, earthworm harvesting, mustard solution, push-pull strategy.
Abstract: The process to recycle lignin-rich coconut leaves, produced in abundance from coconut gardens, to vermicompost, using a local isolate of Eudrilus sp. Is an important value-addition technology from ICAR-Central Plantation Crop Research Institute helping coconut farmers and entrepreneurs to enhance their economic returns. Vermicompost is produced in cement tanks and at the end of the composting period, earthworms are hand-sorted from the mature and partially composted materials by employed workers. The scarcity of labour for earthworm sorting and non-availability of earthworms at the required time for further vermicomposting had become an impediment in sustained production of vermicompost leading to abandonment of the technology by many adopters. To overcome this situation, a simple push-pull /pull-pull strategy was developed for harvesting the earthworms, wherein freshly ground mustard solution was used as repellent (Push agent) and cow dung (with or without bagasse/banana wastes) was used as an attractant (‘pull’ agent).The strategy is simple, efficient and saves on labour , eliminates drudgery, reduces production cost and time. It will pave way for sustained adoption of vermicomposting technology by coconut farmers and entrepreneurs.

Subject: Sharp variations in groundwater levels at the same location: a case study from a heavily overexploited, fractured rock aquifer system near Bengaluru, South India
Keywords: Borehole depth, dewatered zone, fractured rock aquifer, ggroundwater level.
Abstract: Analyses of 83 borehole camera video scans revealed that (i) measured groundwater levels show variations of up to about 200m, even in borewells located in close proximity to each other; (ii) water-bearing joints located at shallow depths in deeper borewells often produce cascades of water which flow down-hole till they meet the water level; (iii) the downward flow recharging waters directly through the existing borewells shafts lead to the formation of a dewatered zone below the recharge zone and above the saturated zone, and (iv) the borewells completed in the dewatered zone show a direct relationship between water level and well depth-deeper the borewell , deeper is the water level. Only the currently yielding borewells, with atleast one water-yielding joint below the water level rise a fair estimate of the regional groundwater table.

Abstract: In this study, Klebsiella variicola BF1 that uses cassava starch wastewater to produce flocculants was identified using 16S rDNA gene sequencing. The pure flocculants of strain BF1 could be easily extracted by ethanol precipitation with a high yield of 7.5 g/l. It was mainly composed of 83.1 % carbohydrates and 10.6 % proteins. The flocculating activity revealed 97.6 ± 0.6 % for kaolin suspension at 12.8 mg/l CaCl2.Interestingly, the flocculating activity was 78 % without the addition of metal ions. Furthermore, flocculants of strain BF1 can be effectively applied in the treatment of cassava starch wastewater and municipal wastewater.

Abstract: Geogenic and anthropogenic activities are the main reasons for the deterioration of groundwater quality. Different kinds of microbial pathogens present in drinking water are responsible for gastrointestinal and waterborne diarrhoeal diseases. The present study estimates the microbial quality of drinking water of Amarja reservoir catchment in Aland taluk, Karnataka, India. Thirty-two water samples were taken from different villages in the study area. Microbiological parameters like Escherichia aeruginosa, sulphite-reducing anaerobes and aerobic plate count at 37°C was analysed. The results showed that 18 of the 32 samples were positive for E. coli and total coliform, 17 samples for P.aeruginosa and 18 samples for sulphite-reducing anaerobes. Moreover, six samples were positive for both E. coli and sulphite-reducing anaerobes, whereas five samples were positive for sulphite-reducing anaerobes and P.aeruginosa.

Subject: Evaluation of a crop growth model for sweet potato over a set of agro-climatic conditions in India
Keywords: Crop phenology, calibaration, growing degree days, SPOTCOMS, simulation.
Abstract: A study was conducted to evaluate the wider applicability of sweet potato growth model, ‘SPOTCOMS’ for simulating the phenology and yield over asset of agroclimatic conditions in India. The model simulated the phenology of the crop as a function of growing degree days. The genetic coefficients required for the model were estimated from the field experiments conducted with sweet potato variety, Shree Bhadra and other local varieties at the study locations. The model simulated the yield of the sweet potato well and the statistical indices calculated between the simulated and observed yields stated the reliability of the model simulations. The agreement index (D-ind3ex) for sree Bhadra ranged from 0.55 to 0.99, and the D-index for local varieties ranged from 0.55 to 0.99, and the D-index for local varieties ranged from 0.51 to 1.00.The calculated values of normalized objective function ranged from 0.01 to 0.10 for Sree Bhadra and 0.00 to 0.22 for other local varieties, and indicated better agreement of simulated and observed yields. The normalized root mean square error ranged from 0.80 % to 10.40 % for sree Bhadra and 0.00 % to 22.44 % for other varieties, and these results suggested the wider applicability of the model with excellent to good simulations. The mod3el also simulated dry matter distribution in tubers pertaining to different stresses such as water, nitrogen and potassium. The study revealed that the simulation model ‘SPOTCOMS’ can be used for simulating the yield as well as to manage the stresses during the crop growth period and to optimize best management practices for the crop cultivation irrespective of the agroclimatic conditions.

Subject: Development of avalanche information system using remote sensing and GIS technology in the Indian Karakoram Himalaya
Keywords: Avalanches, geographic information system, remote sensing. Snowfall
Abstract: Snow avalanches pose severe threat to lives and property in snow-bound regions of the Western Himalaya. The Karakoram Range in Western Himalaya has the highest mean elevation and is the most glaciated region compared to other ranges. Snowfall in this range is frequent even during summer season. Snow accumulation on mountain slopes results into frequent snow avalanches and several lives have been lost due to snow avalanches in the past. In this communication we discuss about the development of avalanche information system using remote sensing and geographic information system (GIS) technology for the Indian Karakoram Himalaya. High spatial resolution (0.5m) PLEIADES satellite images and digital elevation model (DEM) of ASTER GDEM V2 (30 m) and Cartosat (10M) have been used here. Terrain parameters, eg. slope, aspect, elevation, etc. have been derived using DEM. Sites in avalanche-prone areas have been identified using terrain parameters and snowfall information. Villages in the region, camp locations of border guarding personnel, pedestrian routes followed by villagers and border-guarding personnel, avalanche sites along pedestrian routes, etc. have been digitized using appropriate GIS vector features, eg. point, line and polygons. Past avalanche accidents along pedestrian routes, past avalanche occurrences, climatology of the region, etc. have been mapped in GIS environment. Remote sensing and GIS technology proved to be useful for the development of avalanche information system in digital form. The system is being used for avalanche forecasting and mitigation of avalanche hazard in the Indian Karakoram Himalaya.

Subject: Development of composite radial filter for recharging aquifers can l water
Keywords: Aquifer, artificial recharge, canal water, composite radial, filter
Abstract: A laboratory scale model of composite radial filter was designed, fabricated and tested for recharging aquifer with canal water. Charcoal (C), coarse sand (CS) and gravel (G) filter materials were placed in annular rings of developed radial filter in different combination of thickness, viz.1:1, 11:1, 1:2, 1:2:2 and 1:2:1 for four treatments T1, T2, T3 and T4 respectively. Flow equation for discharge through composite radial filter was developed and verified through experiments. The design depth of the filter for given discharge was also obtained. Sodium hypochlorite solution was injected through chlorination unit at the outlet of the radial filter to remove the bacteriological contamination of filtered water. The performance of composite radial filter was evaluated by analyzing canal water before and after filtration. Water Quality parameters of filtered water were found to be within permissible limit at low flow rate (0.3 lps) .The water quality parameters of filtered water from treatment T3 with thickness of 10, 20 and 20 cm for C, CS and G respectively was found to be comparatively better than other three treatments (T1, T2 and T4).The composite radial filter consists of C, CS and G filter media having thickness in ratio of 1:2:2 was found to be the best for recharging groundwater aquifer with canal water.

Subject: An integrated approach in developing flood vulnerability index of India using spatial multi-criteria evaluation technique
Keywords: Flood vulnerability index, morphometric analysis, probable maximum precipitati0n, probable maximum run-off, run-off potential, spatial decision support system.
Abstract: In recent years, flash floods took place in various parts of the country that are not under floodplains due to high rainfall events, causing damage to rail, road and urban infrastructure. There is a need to develop a flood vulnerable index map of the country for precautionary measures in such vulnerable areas. Developing flood vulnerability index (FVI) at country level in India is a multifaceted job due to huge variations in topographic, meteorological and hydrological conditions over space and time. The paper focuses on developing a scientific approach in preparing FVI map of the country in a spatial decision support system environment by using space-based inputs, topographic data and long-term meteorological data. Probable maximum precipitation (PMP) and high rainfall frequency were computed using 100 years daily rainfall data of the country. Runoff potential of the country was prepared sing high resolution landuse, soils, and digital elevation model grids. Probable maximum run-off was further computed at national level using PMP and run-off potential grids. Morphometrric analysis was done using topographic and drainage information. All these layers were normalized and integrated in SDSS environment to compute the flood vulnerability index of the country. Suitable weights were given for all layers using the knowledge base reviewed across the globe. Sensitivity analysis and validation were done using the previous flood incidents.

Subject: Household-level food and nutrition insecurity and its determinants in eastern India
Keywords: Household food security, food policy, calorie intake, under-nutrition
Abstract: Past studies have reported serious levels of food insecurity and under-nutrition existing in the eastern belt of India. This study specifically examined the food consumption pattern, levels of nutrition intake and nutrient intake gap of sample households in 12 villages of Eastern India based on data collected during the agricultural year 2011-12. The results point to serious levels of nutrient intake deficit in the sample villages, though with notable disparities in its level of incidence. Major socio-economic and demographic variables that determine the calorie deficit status of the households were identified, the knowledge of which is important while planning interventions.

Subject: Overview of damage assessment of structures
Keywords: Bridges and buildings, damage index, loss assessment, seismicity
Abstract: Different available analytical and experimental methodologies of local and global damage index (LDI and GDI) determination for bridges and buildings along with their mathematical expression are reviewed in this article. In the literature, impact of seismic loading and material deterioration due to ageing effects is the main focus to study the performance. Case studies for assessment of bridges and buildings are appended here to understand variation of damage index (DI) for various levels of seismicity. The utility of the proposed methods has been discussed in this case study. This article also includes progressive development, limitations and directions of future research on damage assessment of structures. Based on the extensive literature review, the authors have critically analysed the pros and cons of the available methods. However, time-dependent damage assessment, damage estimation for various structural and non-structural components using different materials, variation of damage for different configurations of structures, and deterioration of roads and bridges are the probable future scope for research. In future, damage-based design considering multiple response parameters along with uncertain load, blast load, floods and accidental load could be considered to select allowable damage of structures that would help to understand and ensure the time-dependent safety, progressive phases of collapse and serviceability with high reliability satisfying smart structural requirements.
