Abstract: This study aims to solve the problem of uncoordinated interests among the stakeholders in the operation stage 9OS) of green buildings (GBs) .First, the requirements and conflicts between the owners and property service enterprises (PSEs) are analysed. Secondly, the evolutionary game model of owners and PSEs is developed. It was found that the game system will evolve towards the ideal equilibrium stability strategy only under the following conditions: (1) the income of owners in green property management (GPM) is greater than the sum of the income of PSEs shared by the owner in GPM and the transaction costs generated when the owners choose to support GPM, and 11) the sum of the income of PSEs shred by the owner in GPM and the additional benefits that PSEs can get by choosing GPM and the additional benefits that PSE s can get by choosing GPM is greater than the total cost incurred by PSEs in choosing GPM. We carried out quantitative tests for equilibrium stability results and analysed factor that influence the evolution path based on simulations performed in MATLAB. The results show that improving the operational income of GBs, increasing the additional income of PSEs, reducing the operating transaction costs and adopting a reasonable revenue sharing method are effective ways to coordinate the interests of all parties involved in the OS of GBs.

Subject: In vitro regeneration of coconut plantlets from immature inflorescence
Keywords: Clonal fidelity, coconut, in vitro regeneration, rachillae
Abstract: Clonal propagation of elite, disease –free coconut palms is a promising technique for producing uniform planting material with high yield and disease resistance. Over the past few decades cloning of coconut has been attempted in a number of laboratories worldwide; however, success has been limited. In the present study, immature inflorescences of 2-12 cm size were collected from West Coast Tall variety and the rachilla segments were cultured on four different media combinations in dark conditions. White translucent outgrowths were maximum in Y3 medium supplemented with 4.54 µM 2,4-dichlorophenoxyacetic acid (92%) followed by medium 72 with 41.4µM picloram, 61.8µM putricine and 4.54 µM and 4.54 µM thidiazuron picloram, 61.8 µM putricine and 4.54 µM thidiazuron (TDZ) (87%) .After eight weeks in dark, shoot-like outgrowth was noticed more inY3 III (65%) followed by Y3 I. After eight weeks in dark, shoot-like outgrowth was noticed more inYE III (65%) followed by YI. After eight months dark incubation, the cultures were transferred to ½ Murashige and Skoog (MS) with two hormone combinations and high frequency of multiple shoot formation was noticed in ½ MS with two hormone combinations and high frequency of multiple shoot formation was noticed in ½ MS with 5.37 µM naphthalene acetic acid (NAA) and 4.44 µM 6-benzylaminopurine (BAP).Maximum shoot development was observed Y3 medium fortified with 5 µM 2-isopentenyl adenine (2ip) and 5 µM BAP. The individual shoots after development of 3-4 leaves were transferred to ½ Y3 medium supplemented with 5.37 µM NAA and 24.6 µM indole-3-butyric acid (IBA), and root initiation was observed in 39.28 % plantlets. Start codon targeted (SCoT) profiling based on banding pattern of PCR-amplified products confirmed the clonal fidelity of in vitro regenerated coconut plantlets. The study indicates the possibility of developing an in vitro regeneration protocol for coconut using immature inflorescence explants.

Subject: Landslides mapped using satellite data in the Western Ghats of India after excess rainfall during August 2018
Keywords: Debris flows, disaster response, excess rainfall, landslides, satellite data
Abstract: Excess rainfall during August 2018triggered numerous landslides in the Western Ghats region of India covering the states of Kerala, Karnataka and Tamil Nadu. These landslides caused widespread damage to property, loss of life and adversely affected various land resources. In this article, we present an inventory of landslide prepared from the analysis of multitemporal high-resolution images acquired before and after the rainfall event from Resoourcesat-2, WorldView-2,GF-2, SPOT-6 and 7, Pleiades-1, Kompst-3 and Sentinel -2 earth observation satellites. Total of 6970 landslides with a cumulative area of 22.6 sq.km were mapped for this rainfall event. Majority of landslides have occurred in Kerala (5191), followed by Karnataka (993) and Tamil Nadu (606). Landslides are mostly debris slide and debris flow type with entrainment along the channels. Results show that landslides (83.2%) are triggered by very high rainfall. Also, very high rainfall has resulted in 14.9 % of landslides even though sloes are moderate, mainly in the Kodagu district of Karnataka.

Subject: Assessment of rainfall variability and its impact on groundnut yield in Bundelkhand region of India
Keywords: Bundelkhand region, groundnut yield, Indian monsoon rainfall, rainfall intensity class.
Abstract: Bundelkhand region, one of the vulnerable areas in central India, is prone to frequent drought and crop failure due to annual rainfall variability. In this study, longterm (113 years) fine resolution (0.25º x 0.25º) daily gridded rainfall data been analysed to depict a spatial variation of annual rainfall over a Bundelkhand. An increase in annual rainfall has been observed from north to south of the study area. A declining trend varying from 0.49 to 2.16 mm per year is observed in annual rainfall time series in most parts of the study area. Trend analysis of monsoon rainfall shows overall declining trend over the study area. Rainfall events are categorized in various classes and their spatial trends over Bundelkhand are depicted. Kharif crop calendar (July-September) as well as its yield in India, including Bundelkhand, is primarily based on monsoonal rainfall parameters. A study on the relationship between groundnut yield and monsoonal rainfall parameters for a Jhansi district in Bundelkhand shows highest correlation (0.46) between groundnut yield and rainfall class 3 events (16 ≤ rainfall intensity, mm day-1 < 32) occurred in a year followed by cumulative rainfall amount precipitated during June-July (JJ).The frequency of rainfall class 5 type (64 ≤ rainfall intensity , mm day-1 <128) as well as a delay in onset of monsoonal rainfall have shown a negative correlation with groundnut yield. This study depicts rainfall pattern over the study area and identifies the vulnerable pattern over the study area and identifies the vulnerable areas that are likely to experience more water stress due to rainfall variability.

Subject: Summer monsoon of 2019: Understanding the performance so far and speculating about the rest of the season
Keywords: Deficit rainfall in June, ENSO, EQUINOO, Indian summer monsoon
Abstract: The summer monsoon of 2019 began with a massive deficit in the all-India June rainfall of about 33 of the mean. This led to considerable anxiety since a large deficit in June had occurred last in the summer monsoon of 2014, which has turned out to be a drought. Here, we have attempted to unravel the factors that led to the deficit in June 2019 and also the above-normal rainfall in July. We show that the deficit in June 2019, as that of June 2014, can be attributed tit he EI Nino. The phase of the other important mode, Equatorial Indian Ocean Oscillation (EQUINOO), has been favourable throughout and led to the recovery of the monsoon in July when the EI Nino weakened. It is expected that EQUINOO will play an important role in determining that rainfall in August and September, and hence the seasonal rainfall in2019.Analysis of cases like 2003 and 2008, when the positive phase of EQUINOO lasted only during June and July and of 2007, when it lasted throughout the season has given an insight into the role of the sea surface temperature (SST) of the western equatorial Indian Ocean (WEIO) in sustenance of the positive phase of EQUINOO. We find that , unlike in 2003 and 2008, the SST of the WEIO has started increasing in late July, partly due to the mechanism which operated in 2007 and has led to a positive SST anomaly by 10 August , whereas sustained cooling has led to a negative SST anomaly over eastern equatorial Indian Ocean. Since conditions now appear to be favourable for sustenance of a positive phase of EQUINOO, it is expected that the seasonal rainfall will be above normal.

Subject: A critical evaluation of environmental impact assessments: case study of Goa mines, India.
Keywords: Developmental projects, environmental impact assessments, floristic diversity, mines, plant lists, species and area.
Abstract: Environmental impact assessments (EIAs) form the basis of estimation of environmental and socio-economic impacts of developmental projects. In this study we examine 65 EIA reports of mines in Goa. It is mandatory that the reports should provide, among others, list of plant species from 314.2 and 78.5 sq.km area for lease areas of mines above 0.5 and below 0.5 sq.km respectively. On the basis of available data covering different spatial scales for the Western Ghats, we determined the species-area relationships, and expected number of species in area of these sizes. We find the plant lists in the EIA reports to be highly incomplete and defective in many ways, including with respect to information on water resources, and ore transport by trucks and barges. We conclude by commending a set of measures focusing on transparency and public involvement to correct the situation.

Abstract: Floods are the most common and recurring natural hazards faced by humans since time immemorial. They pose a severe threat to the population, environment and economy in many places across the world, especially urban areas. Urbanization caused due to increasing migration into the floodplains has substantially increased the trend of devastation due to floods in a developing country like India. In Chennai and the surrounding suburban areas, torrential rainfall associated with low-pressure systems engulfed the city during December 2015, affecting more than 4 million people along with economic damages that cost around 3 billion USD. In view of the above-mentioned extreme event in Chennai, it was felt necessary that an expert system be designed for flood forecasting along with flood inundation maps and possible means of flood management through appropriate interventions for dealing with any such future events.

Keywords: Chandipur, crab burrow morphology, crab energetic, Ocypodidae
Abstract: Several burrow morphological features of crab Ocypode ceratophthalma including burrow diameter, orientation, inclination, branching and volume were studied from Chandipur, a sedimentologically and biologically diverse beach on the eastern Indian coast. Burrow morphologies (e.g. I, J.Y) were independent of their positions with respect to the coast line. In addition, no correlation between burrow morphology and burrow diameter was observed; however, diameter of burrow appeared to be a good proxy of the total amount of sediment excavated. Burrow diameters are significantly smaller in the foreshore compared to that of the backshore, suggesting that larger individuals reside along the backshore, where they excavate deeper and large-diameter burrows to minimize chances of desiccation. Smaller burrows are motre or less vertical, whereas larger burrows are inclined towards the land, probably to stabilize their domicile from tidal activities, as well as to minimize energy required to excavate sediments. All these suggest that different types of abiotic factors determine the Ocypode burrow morphology and their habitat segregation.

Abstract: A field experiment was carried out on screen the sorghum genotypes against stem borer in rice fallow under zero tillage condition. Based on mean stem tunnel length, the genotypes were categorized as least susceptible (0-5 cm) , moderately susceptible (-10 cm) and highly susceptible (>10cm) .The resistant check CSH 16 (C) was found least susceptible with 4.65 cm, whereas NTJ-2 (C),NLCW-6 and N-14 were found to e highly susceptible as they recorded 10.45, 10.46 and 11.44cm mean stem tunnel length respectively. The remaining genotypes were moderately susceptible with 6.60-9.84 cm mean stem tunnel length. There was non-significant positive correlation between the number of larvae and leaf damage, dead hearts, stem tunnelling, white ears and chaffy grains respectively, but it was negative for tiller damage.

Abstract: The cognitive appreciation of seismic risk among the local population is one of the key drivers in the adoption of the guidelines issued for earthquake-resistant masonry construction. The present study gives a broader perspective on the cognitive vulnerability that exists among the local population in understanding and adopting the proposed earthquake-resistant construction guidelines based on a detailed evaluation of the prevailing practices at two regions in Kerala, India. The exercise was carried out among 197 houses located in the above region s, which included both recently built homes and those with exposure to earlier earthquakes. The study highlights the need for evolving technology-supported intelligent interactions that would help the stakeholders take appropriate decisions on various disaster-resistant practices.

Abstract: Herein, we assess the relative potential of single-walled, multi-walled and graphitized multi-walled carbon nanotubes (CNTs) for the adsorptive removal of organic species using aniine and nitrobenzene as model aromatic contaminants. The obtained results reveal that the adsorption behaviour of aromatic organics is significantly affected by their functional groups (especially when functionalized CNTs are used as adsorbent), providing valuable guidance for adsorption-based removal of organic contaminants from the environment.

Subject: Changes in behaviour following a ‘rank changeover by challenge’ in the Nicobar long-tailed macaque (Macaca fascicularis umbrosus)
Keywords: Between-group encounters, grid use, Nicobar long-tailed macaque, rank changeover, reproductive behaviour
Abstract: A rank changeover is a sequal strategy by primate males to gain access to reproductive females. We observed one such event in the Nicobar long-tailed macaque (Macaca fascicularis umbrosus) at the great Nicobar Island, India. In the three and half months of the post-rank changeover period, the home range reduced significantly while there was no change in the intensity of range use and day range length. The sleeping sites in the post-rank changeover period were confined to the centre of the home range. The overall mating rate and aggressive mating approach by males increased significantly during the post-rank changeover period. The females developed sequel swelling and started soliciting the immigrated males within two weeks after the rank changeover event. During this period no female conceived, which suggests that they used situation-dependent receptivity with deceptive swelling as a counter strategy to avoid male aggression for copulation.

Subject: Estimating stream piracy in the lower Ganga Plain of a Quaternary geological site in West Bengal, India applying sedimentological bank facies, log and geospatial techniques
Keywords: Bank materials, geospatial technique, interfluves, quaternary sites, stream piracy
Abstract: River Bhagirathi is a distributary channel of River Ganga, and Babla is one of its right-bank tributaries in the Ganga delta plain. The Bhagirathi flows in a meandering pattern through the New Quaternary alluvium plain, whereas the Babla flows through the Old Quaternary deposits of yellowish –brown sand, silt and clay. As the Bhagirathi is a distributary of River Ganga, it brings in million tonnes of sediments annually. Mid-channel bar formation, bar dynamics and non-cohesive nature of bank materials promote bank failure and rapid shifting of the channels in the Newer Quaternary sites. As the Bhagirathi migrates towards River Babla, the interfluves zone is being progressively engulfed by the course of the former. To estimate the stream piracy or capture, bank materials, internal organization of mid-channel bar, flow parameters (velocity, channel depth, discharge, etc.) have been taken into consideration. This study documents changes in channel morphology and hydrological parameters, dynamic morphology and hydrological regime of the fluvial system from 1852 to 2017.It predicts the actual time when the Bhagirathi will capture River Babla near village Natungram. The study also discusses why in recent years the rate o lateral migration has increased for a particular portion on the right bank of River Bhagirathi near Natungram.
