Abstract: Improving living standards, economic, an industrial expansions, and population growth are posing serious challenges for the Indian energy sector. Although the country is recognized as one of the fastest growing economies of the world, the basic energy needs of thousands of millions of its citizens are yet to be fulfilled. Likewise, its commercial energy consumption is also growing with the same pace as that of high economic growth and industrial development. Being an agriculturally dominant nation, the strength of India ' s bioenergy programmes mostly lies in the agricultural sector.

Abstract: Decreasing the production cost of microalgae cultivation is the central challenge of microalgae bioenergy development. The cost of nutrients and biomass harvesting are two major factors that limit the algal biofuels from being economically feasible. These factors are reduced by integrating the photo-bioreactor and the anaerobic digestion. In the present work, a closed loop was developed for the sustainability of the feedstock and water with the production of biomethane under outdoor conditions. The integration of photo-bioreactor and anaerobic digestion was done to improve the economics and energy balance o biofuel production. Therefore, a novel concept has been introduced in this article that reduces the total production cost of biomethane by minimizing the usage of fresh water and external nutrient source for algal growth. Algae were tested for their biomethane production potential in Anaerobic Digester (AD) wastewater.

Abstract: During the present investigations, tree species were documented from Lohgad and Visapur forts which occupy a small geographical area in Western Ghats (one of the important global biodiversity hotspots and UNESCO ' S World heritage site) near Lonavala and Khandala hill stations. Tree species were identified and number of families, genera and species were recorded along with their endemic and threatened status. Literature survey was made as a source of secondary data for comparative account. In all 194 tree species belonging to 134 genus and 48 families were recorded. Moraceae was dominant family followed by Mimosaceae and Euphorbiaceae. Twenty six non-native cultivated species were recorded. From the results it is concluded that, Lohgad-Vispur forts region is highly diverse but under the anthropogenic threats due to various developmental projects (irresponsible tourists, construction of roads and other infrastructure) and introduction of non-native species. Due to rich diversity and well-nourished habitat for the wildlife, this region was proposed for Santapau Wildlife Sanctuary. If protected well, it could b the corridor and nourishing habitat for wildlife of the area.

Abstract: The reclamation of wasteland and development measures in general includes land clearing, soil and water conservation, enhancing nutrient status, provision of irrigation facilities and so on. However, the existing status of wastelands shows wide variation across different regions of the country in terms of their suitability for cultivation. Therefore, it is necessary to carry out a scientific assessment of the existing status; fertility, erosion levels, soil conditions, water potential, suitable cropping system, etc. of the waste lands spread over different agro-climatic zones of the state so as to prepare a realistic reclamation-cum-development plan for the wastelands. Thus rehabilitation of the wasteland through the sustainable management serves as a better cover to the soil and aids regeneration of forests.

Keywords: Indian lac, Export scenario.
Abstract: Lac is a natural resin which finds wide utility in commerce and industry. India being the largest producer of lac in the world has a great export potential. The present study was carried out with a view to analyze the export scenario and potential of lac in India. The data were collected and analyzed for a period of 40 years (1971-72 to 2010-11). The compound annual growth rate in export of lac was worked out by fitting the exponential function. Analysis of data show that the quantity of lac exported from India has shown a declining trend (0.48 % per annum) over a period of 40 years, possibly due to decrease in domestic production and high prices of lac. Export earnings have exhibited significant positive growth rates of 9.00 % per annum for the same period. The lac from India is exported in various forms viz.shellac, seedlac, dewaxed shellac, bleached lac, aleuritic acid, gasket shellac, shellac wax, etc. The data of last five years have indicated that the largest quantity is exported I nth form of shellac (74.26 per cent) followed by seedlac (15.99 per cent), bleached lac (4.04 per cent), dewaxed shellac (3.77 per cent) and aleuritic acid (1.43 per cent). The share of gasket shellac and shellac wax is very small. The major export destination (in terms of value) of Indian lac was Indonesia (13.77 % of total export value), Pakistan (11.50 %), U.S.A. (10.94 %). Proper attention an action for intensification of efforts for increasing lac production, exploitation of untapped potential area, quality consciousness, more R & D support for product development and removal of other export related constraints will definitely improve the export scenario and export earnings of the country.

Abstract: The pressure paper deals with the invasive alien plants found in the state of Himachal Pradesh, India. A total number of 125 invasive alien species under 83 genera, belonging to 39 families have been recorded based on field observations, herbarium and literature consultation. Tropical American elements contribute 75% of alien species found in the state. Among the invasive, annuals comprise 63 %, herbs constitute 79 % and only four tree species recorded as invasive species. Invasive species based habitat shows that 44 % of invasive species were most abundant in wasteland, while cultivated fields, roadsides and forests were preferred by 20, 16 and 9 % species respectively. Among the invasive alien elements, 70 species (56 %) are being used by local inhabitants for different medicinal uses. Early detection and monitoring of naturalized weeds are essential for better control.

Abstract: Practicing lateral pruning as a management practice has given results that there is a significant increase in increment per cent in height of the poplar trees when they are laterally pruned up to 25 % clear bole, 75% clear bole or 100 % clear bole. However, the pruning intensities do not make any difference in the height of trees when compared among themselves. The results also reveal that there is a significant effect on increment per cent in diameter over control. However, there is no significant effect on increment per cent in dbh among different pruning intensities. As there is significant difference in height and dbh due to various pruning intensities, the same is reflected by the volume of the trees. The maximum commercial volume is obtained in 100 % pruning intensity which is 178 % more over control followed by 25 % an 50% pruning intensities which are significantly at par. Pruning management also reduces the number of female catkins considerably when trees are pruned up to 50 %. The number of catkins gets reduced by 80 %.Hence it is suggested that the poplar plantations should be intensively pruned leaving at least 50 % clear bole to get knot free timber and reduce the cotton menace by 80 %due to dispersal of seeds during the month of June and July. This pruning should be done in autumn and till the plantation achieves a height of 15 meters because up to this height the trees can be pruned without much effort.

Abstract: Twenty-three tree willow clones comprising of seven species were studied for variability of photosynthesis traits and their relationship at one year age. Photosynthesis, transpiration and instantaneous water use efficiency (WUEi) were determined and the data were further subjected for the estimation of genotypic and phenotypic coefficient of variability (GCV and PCV), heritability and genetic grain (as per cent of mean).Variability estimates were calculated for growth parameters viz., height, collar diameter, volume index, number of branches, number of nodes, intermodal length, leaf display and leaf area. Among all the parameters volume index showed widest range of values (9.29-721.50, mean 356.42). The narrowest range was recorded for leaf display (195.0-291.0, mean 238.17).The maximum GCV (39.99) was recorded transpiration, followed by photosynthesis (38.36) and least in case of WUEi (19.71). Heritability (h2b.s) was recorded maximum (85.30) for transpiration, (80.00) for photosynthesis and (26.55) for WUEi. A positive significant correlation (r =0.754) was observed between photosynthesis and transpiration. WUEi showed significant negative correlation (r = -0.364) with transpiration whereas positive non significant (r = 0.209) with photosynthesis.
