Indian giant squirrel (Ratufa indica) has been found as an indicator of good health of forest as it feeds on most of the parts of trees like flower, fruits, leaf, bark and young shoots of a variety of species. Although it nests on diverse variety of plant species but mostly prefers tall trees like Terminalia tomontosa, Dillenia indica, D. pentagyna ,etc. It prefers to nest on the top of the trees. Though Indian giant squirrel feeds on parts of many plants but plant like iImli, mahulan, pakur, pipal, pant, barhgad are very important as the leaves and young shoots are eaten more and more by these animals. Forest with presence of a mixed deciduous forest where it could get diversity of trees to nest and feed on. Such trees provide an ideal habitat for this squirrel. Indian giant squirrel preferred a mixed deciduous forest, where it could get diversity of trees to nest and feed on. The discontinuity of tree cover, due to illegal felling, cutting of branches to feed the domestic animals by local villagers and illegal hunting (bishu shikar, poaching) have been the major threats for the survival of the Indian giant squirrel.Keywords

Rainfall, an integral component of the global water and energy cycle, is one of the critical weather elements. Reliable information of rainfall over India is crucial for food security and sustainable economic growth. The first Indian dedicated meteorological geostationary satellite Kalpana-1 was launched by the Indian Space Research Organisation in late 2002 to study the synoptic weather systems, monsoons and extreme weather events. Various geophysical parameters derived from this satellite measurements are operational and used for a wide range of applications. Two rainfall products, based on distinct algorithms, from this satellite are also available to users. These two algorithms after certain refinements are also applied to the recently launched INSAT-3D satellite measurements to estimate rainfall. In this article, the algorithms used for the development of these Kalpana-1-based rainfall products are summarized. The assessment of these rainfall products against standard multisatellite datasets and in situ observations are also outlined. Both the rainfall products are comparable with independent multisatellite datasets and have reasonable agreement with ground-based observations over the Indian land and oceanic regions. Limitations of these rainfall products are also presented; and future scope for further refinement of these products in perspective of upcoming Indian geostationary satellite missions is proposed.Keywords

We report data on nitrate, ammonium and urea uptake rates from the Equatorial and Southern Indian Oceans. Productivity (0.81-2.23 mmol Nm-2 d-1) over the Equatorial Indian Ocean was low, but the f-ratio (0.13-0.45) was relatively high. In the Southern Indian Ocean total N-uptake rate varied from 1.7 to 12.3 mmol Nm-2 d-1; it was higher in the Antarctic coast (69°S) and lower over most of the Southern Ocean, the lowest being at 58°S. The f-ratio also showed significant spatial variation, but was higher compared to values at the Equatorial Indian Ocean. The mean f-ratio in the Southern Indian Ocean was 0.50. The nitrate-specific uptake rates and f-ratios appear to have increased significantly in the recent past relative to earlier estimates. While productivity in the Southern Ocean is comparable to that in the Equatorial Indian Ocean, higher f-ratios in the former underscore its importance in the uptake of CO2.Keywords

Terrestrial water storage (TWS) plays a key role in the global water cycle and is highly influenced by climate variability and human activities. In this study, monthly TWS, rainfall and Ganga-Brahmaputra river discharge (GBRD) are analysed over India for the period of 2003-12 using remote sensing satellite data. The spatial pattern of mean TWS shows a decrease over a large and populous region of Northern India comprising the foothills of the Himalayas, the Indo-Gangetic Plains and North East India. Over this region, the mean monthly TWS exhibits a pronounced seasonal cycle and a large interannual variability, highly correlated with rainfall and GBRD variations (r > 0.8) with a lag time of 2 months and 1 month respectively. The time series of monthly TWS shows a consistent and statistically significant decrease of about 1 cm year-1 over Northern India, which is not associated with changes in rainfall and GBRD. This recent change in TWS suggests a possible impact of rapid industrialization, urbanization and increase in population on land water resources. Our analysis highlights the potential of the Earth-observation satellite data for hydrological applications.Keywords

Renewable energy sources are becoming more attractive due to their eco-friendly nature. As conventional energy sources are polluting environment, it has become imperative to shift to renewable energies. PV and wind are popular renewable sources because of their abundance availability and cost effectiveness. But, renewable do not being able to supply continuous power owe to intermittency of renewable sources. This issue can be addressed by efficiently integrating battery with renewable sources. The usual approach for this is to use dedicated single-input converters one for each source. In this, the sources are connected to a common dc bus. The special converters which are used for the integration purpose would not work properly due to renewable intermittency. The efficiency of integrated system would be decreased due to multiple power conversion stages. So, the major challenge is to decrease power conversion stages and hence losses of hybrid system. A control technique has been proposed in this work for tracking Maximum Power Point (MPP) of both wind turbine and photovoltaic array through adjusting the duty cycle ratios of switches used in converters under varying climatic conditions.Keywords

Sustainable agricultural development requires a systematic effort towards the planning of land use activities in the most appropriate way, apart from several other institutional and policy programmed initiative. Remote sensing can provide valuable and timely information about natural resources and environment as an important basis for sustainable development. Geographic information systems (GIS) can provide effective tools for decision makers. Both RS and GIS techniques are important geometric tools which are extensively utilized in developed countries. This technology is also used for land use planning and soil mapping. Modern tools such as satellite remote sensing and geographical information system (GIS) have been providing newer dimensions to effectively monitor and manage land uses in an integrated manner for agricultural characterization. Remote sensor and G.I.S. is an excellent tool that is increasingly important in the detection, description, quantification and monitoring environmental changes is remote sensing, which, in combination with geographic information systems and fieldwork, is an effective management tool.

In 2015, a Noctiluca scintillans bloom and associated water column properties were studied in the northern Arabian Sea. Our observations showed photic depth limited to 30 m with uniform oxygen concentration of ~223 μM. In general, the dissolved oxygen ranged between 180 and 223 μM within the top 80 m indicating saturated mixed layer. Chlorophyll a varied between 0.24 and 2.4 mg m–3 within the core of the bloom and <0.1mg m–3 outside. We further examined Argo oxygen data from 2006 to 2013 to delineate possible surface water hypoxia associated with the initiation of N. scintillans bloom. Oxygen profiles from Argo data suggest oxic upper water column (~ 50 m) with strong seasonal shoaling. Our results do not indicate any mixed layer oxygen depletion associated with the N. scintillans bloom or any evidence of surface water hypoxia in the past. However, examination of silicate/nitrate (Si/N) climatology suggests strong longitudinal variation. The silicate in the surface waters in the northwestern Arabian Sea is depleted much earlier (Si/N < 1) compared with the eastern part, resulting in a strong spatial trend. This presumably facilitates easy community transition to a N. scintillans bloom. This is supported by the heterotrophic nature of the species which, under detectable and below-detectable nitrate conditions, gives it a competitive advantage over other phytoplankton communities.Keywords

Groundwater reflects the major percentage of the world’s freshwater resources, for a human being it is a dynamic natural resource to fulfill their day to day life requirements. Groundwater is essential for human being along with animals, trees, aquatic living organism etc. Due to urbanization, industrialization, mining, irrigation, domestic demands and so on, the demand of water is hugely increasing. In present stage water resources are depleting drastically on account of access exploitation, mismanagement etc. so its conservation and management are significant. Using Geospatial technology, this study has demonstrated the variability in groundwater prospects with respect to spatio-temporal changes in Ranchi city and its nearby area, Jharkhand, India, based on thematic maps of LU/LC, drainage, lineament, slope, and aspect. The groundwater potential has been categorized in four categories viz., very poor, poor, moderate and very good. The Geospatial technology is the modern, innovative and dynamic technique used for M-3 movement that is monitoring, mapping and management of various environmental issues with its specific capability. The high-resolution remote sensing data of years 1998, 2004, 2010 and 2016 have been used for various modeling and mapping along with the GIS environment to assess the groundwater prospect variability with LU/LC changes.Keywords

India received anomalously deficit southwest monsoon rainfall during 2014 and 2015, which resulted in consecutive droughts across the country. Reliable detection and monitoring of droughts are crucial for the reduction in drought vulnerability and associated socio-economic impacts. In this study, the potential of multiple high-resolution satellite datasets is examined using distinct drought indices over India for these two successive monsoon seasons. The satellite-derived precipitation, soil moisture and land surface temperature estimates are capable of depicting the anomalous drought conditions with some exceptions. A non-parametric multivariate standardized drought index, based on precipitation and soil moisture estimates is proven to be better in the detection of droughts when compared to conventional standardized drought indices. Overall, remote sensing satellite datasets provide immense opportunity to detect and monitor different kinds of droughts using a composite of indices. However, limited temporal records of these high-resolution satellite datasets restrain their applicability from the climatological perspective.Keywords

A field study was conducted in Ghaziabad district to observe the effect of mineral mixture feeding on milk yield in Buffalo. Animals were selected randomly from 5 villages of Ghaziabad (U.P.) (Muradnagar, Noorpur, Kanoja, Kusalia, and Badka). 20 Buffaloes were selected in their 2nd and 3rd stage of lactation and divided into two groups of 10 animals each. First group (T) was fed with 60 g mineral mixture daily till 90 days of lactation. Other group (C) of 10 animals were not fed additional mineral mixture, which is farmers practice in that particular area. The farmers were not fed scientific method of feeding. They could not added proper quantity of mineral mixture in balance ration. To keeping in mind a trial was conducted in Ghaziabad district since 2016-17 (2017-18). Milk yield of these animals was recorded by their owners and these values were averaged for fortnightly interval. Milk production parameters like average daily milk yield, peak yield and total milk yield were compared between treatment and control groups. It was observed that average daily milk yield, peak yield and total milk yield were found significantly (P < 0.05) higher by 11.04, 12.37 and 11.61 per cent in mineral mixture fed group than control group. On the basis of this, it is recommended that continuous feeding of mineral mixture bettered performance of milk yield in buffaloes.
