Abstract: An enumeration of 105 species of lichens belonging to 48 genera and 21 families recorded in and around Nainital city in the Uttarakhand is provided. The localities around the city centre exhibit scarce growth of lichens as compared to the localities situated in the outskirts. The Snow View and Kilbury localities situated in the outskirts of the city have maximum diversity of lichens represented by 34 and 28 species respectively. The Ayarpatta and D.S.B campus area in the centre of the city have 19 and 9 species respectively. Among the different trees Quercus supports the maximum growth of lichens. Lichen genera Heterodermia with eith species and Caloplaca and Lecanora with seven species each showed their dominance in the area. Lichen families Parmeliacae with eleven genera physciaceae with eight genera are the dominant families in the area.

Keywords: Dendrocalamus strictus, Bamboo resources, Natural Bamboo Forest, Homestead Bamboo Cultivation, Bamboo Diversity
Abstract: Studies have been conducted to assess bamboo resources at both forest and non-forest areas in the state of Jharkhand. Information on land use, bamboo overlapping areas in forests, demographic features of the villages, households owning bamboos, species diversity, their growth, productivity etc. have been collected on sample survey basis covering all the agro-climate zones of the state. 14.51% of total forest area (TFA) is covered with potential natural bamboos of mainly Dendrocalamus strictus (<98% area) with average clump density of 170 (clumps ha-1). Other species encountered are Bambusa bambos and Gigantochloa albociliata. The natural bamboos are in a state of severe degradation due to indiscriminate felling by villagers, absence of any management system and lack of state vigilance.
From the villages of Jharkhand altogether 10 bamboo species have been found with dominant species being Bambusa nutans (representing 84.582% of TBA and 1.314% of TGA), Dendrocalamus strictus (11.924% of TBA and 0.185% of TGA) and Bambusa bambos (2.257% on TBA and 0.035% on TGA).
1.554% of TGA is covered by homestead bamboos which is equivalent ot 16.852% of TNA and 10.442% of TNA+CW as per the land use of the state. Contrary to this, 131.769% of TNA or 59.349% TNA + CW in three blocks of East Singhbhum district is under homestead bamboos. This indicate that, by retaining 50% of land under these two land use classes for other domestic purposes, it is possible to extend bamboo cultivation in additional 39.558% of land not used for cultural practices in the state with suitable species and adequate extension mechanism to safeguard ecological and economic scenario of the state.

Keywords: Micro-climate thermal bands, population density, surface temperature, thermal bands
Abstract: Increasing urban surface temperature due to change of natural surfaces is one of the growing environmental problems in urban areas, especially in cities like Delhi. The present work is an attempt to assess the urban surface temperature in Delhi using remote sensing and GIS techniques. ASTER datasets of thermal bands were used to assess the land surface temperature (LST) using termperature emissivity separation technique. Ward-wise population density was calculated from the Census of India 2001 data to correlate the population density with LST. The study shows that surface temperature changes with th eincrease in the impervious surface area, which is related to the increase in the population density.

Abstract: Land-cover changes occurring before 1800 are often ignored in the estimation of CO2 emissions, probably ignored in the estimation of CO2 emissions, probably because they are poorly documented in most tropical countries. India appears to be an exception to this rule. It was possible to reconstitute the main stages of the land-cover history for a large region of SOuth India, and therefore to retrace the dynamics of CO2 emissions during nearly 1000 years. It was then possible to demonstrate that 25% of the total emissions occurred before 1800, and are mistakenly considered as more recent emissions.

Abstract: Our earlier studies reported development of transgenic strawberry for salinity stress and standardization of transformation protocol. In view of the projections of global climate change and their implications on the ability of strawberry to adapt to such changes, we extended oru studies to know the possible role of such transgenic plants in contributing to sustainable strawberry production and also made some basic studies to analyse the behaviour of osmotin (transgene) /in vitro-regenerated trangenic strawberry plants. Ten different lines of transgenic strawberry plants, with osmotin transgene were developed using Agrobacterium-mediated method. Expression of osmotin gene was observed in three transgenic lines and drought tolerance was confirmed. RAPD analysis, within its limits of sensitivity and accuracy, failed to detect any appreciable polymorphism in the genomic DNA of wild and tissue culture-raised (transgenic and control ) platns. No morphological abnormalities were detected in the transgenic lines overexpressing osmotin, although their rate of growht was lesser under in vitro as well as ex vitro conditions, possible due to diversion of energy towards constitutive expressin of osmotin. These plants resumed normal growht and overcome the growth penalty when inoculated with Piriformospora indica. Surprisingly, the overexpression of osmotin, a PR-5c protein with antifungal activity, had no adverse impact on the colonization or symbiotic association of P. indica and Sebacina vermifera with these transgenic plants. We report here on the association of symbiotic fungi with transgenic strawberry and their usefulness in overcoming growth penalty in such transgenic plants.

Keywords: Climate change, drylands, resilience, watershed management
Abstract: The article revies and summarizes the climate change mitigation and adaptation work undertaken by ICRISAT. The effects of climate change area already being experienced in several parts of the world. Even though the effects of climate change will be felt over all kinds of agricultural production systems, they will be more pronounced in dryland areas where agriculture is totally dependent on rainfall. Simulation output analyses reveal that crop yield will decrease due to climate change and variability in drylands, but thus can be mitigated in large parts by the application of existing knowledge on crop soil and water management, and by re-targeting and re-deployment of the existing germplasms of the crops in the medium term (2010-2050). Integrated watershed management is an important tool to mitiagate the climate change effects through soil conservation, improved water availability and other secondary benefits. Similarity, conservation agriculture practices under the integrated genetic and natural resources management strategy genetic and natural resources management strategry can help minimize the adverse effects of climate change on dryland agricultural productivity.

Title: Volatile organic compounds and their measurements in the troposphere

Keywords: Atmosphere, measurement techniques, photochemical transformation, volatile organic compounds
Abstract: Volatile organic compounds (VOCs) are ubiquitous atmospheric constituents of both anthropogenic and natural origin. VOCs are important precursors of tropospheric ozone (O3), and can impact air quality and global climate. Most of primary VOCs and their oxidized products makeup a major fraction of secondary pollutants in urbanized regions. Due to fast reaction rates mainly with the hydroxyl radical (OH), the VOCs control the oxidizing capacity of the troposphere. Measurements of VOCs are important to study the photochemical transformation, both qualitatively and quantitatively. Many aspects of VOCs in the atmosphere remain poorly understood-these include the detection and quantification of by-productss of VOCs, their oxidation reactions and their role in oxidant and secondary aerosol formation. In the photochemistry of tropical troposphere, VOCs play a key role due to high abundance of water vapour (H2O) and intense solar radiation flux. Measuremetns of these species are rare over the Indian subcontinent and surrounding marine regions. Traditionally, gas chromatography-based methods have been used for the detection of VOCs. Recently, the fast time response and sensitive techniques like proton-transfer reaction mass spectrometer are the emerging tools to detect trace levels of various VOCs in the atmosphere.
