Results of a preliminary techno-economic appraisal of solar thermal power generation at three locations in India are presented. The study uses System Advisor Model developed by NREL, USA. The results of the study provide useful insight into (a) selecting appropriate reference direct normal irradiance for design of solar thermal power plants, (b) identifying suitable combinations of solar multiple and hours of thermal energy storage and (c) cost reduction potential. The parabolic trough technology is used for exemplifying the procedure for this purpose.

Many cook stove programs implemented in South Asia and Africa were aimed at reducing fuel wood consumption and pollutants through the use of improved cook stoves. The research work presented in this paper is focused on evaluation of improved cook stoves with respect to thermal efficiency and emission levels. Since the type of biomass fuel varies in different geographical regions, the improved cook stoves must be compatible to use different types of fuel. The present research work is aimed at evaluating three types of forced draft cook stove with two types of biomass fuels.

India is a rapidly urbanizing country and has experienced profound changes in the spatial structure of urban areas. This study endeavours to illuminate the process of urbanization in India using Defence Meteorological Satellites Program - Operational Linescan System (DMSP-OLS) night time lights (NTLs) and SPOT vegetation (VGT) dataset for the period 1998-2008. Satellite imagery of NTLs provides an efficient way to map urban areas at global and national scales.

A next-generation green revolution towards a more sustainable, low-input but still highly productive agriculture is urgently needed. A key for this is below-ground: The intricate interplay of plant roots with the soil microbiota is crucial for natural soil fertility and, thus, for any sound agro-ecosystem.
Modeling urban heat islands in heterogeneous land surface and its correlation with impervious surface area by using night-time ASTER satellite data in highly urbanizing city, Delhi-India
Mallick J, Rahman A, Singh C K
The present study is an assessment and identification of urban heat island (UHI) in the environment of one of the fastest urbanizing city of India, Delhi Metropolis, employing satellite image of ASTER and Landsat 7 ETM+ in the thermal infrared region 3-14 ?m. Temporal (2001 and 2005) ASTER datasets were used to analyze the spatial structure of the thermal urban environment subsequently urban heat island (UHI) in relation to the urban surface characteristics and land use/land cover (LULC).

Sweet sorghum is emerging as a promising energy crop in India, with potential for ethanol production both from the extracted juice and the bagasse residue. This work investigates the release of fermentable total sugars (TS) and formation of total degradation compounds (TDC) by dilute sulphuric acid hydrolysis of sweet sorghum bagasse from the genotype SSV 84. Hydrolysis was conducted at moderate temperatures (100 °C and 121 °C).

In the forested landscapes of India, the livelihood of the people living close to forest and within the forests are inextricably linked to the forest ecosystem. People depend on a variety of forest products for food, fodder, agriculture, housing, and an array of marketable minor forest produces. Forests are not only a source of subsistence income for millions of poor households, but also provide employment to the poor in these hinterlands. This makes forests an important contributor to the rural economy in these regions.

It is a constant endeavour of The Energy and Resources Institute (TERI)—Library and Information Centre (LIC) to cater best information services to the users community, which comprises of research professionals working in the fi eld of energy, environment and sustainable development. Understanding the consumer of data, information and knowledge to accomplish the projects, is becoming increasingly important in relation to the appropriate designing and development of information products and services ‘tailoring’ to the needs of these users.
Influence of land use/land cover (LULC) changes on atmospheric dynamics over the arid region of Rajasthan state, India

The present study examines the long-term effects of land use/land cover (LULC) changes in Rajasthan state, India on land-atmosphere fluxes and, possibly in precipitation and aerosol loading. By comparing the satellite observations from Landsat MSS (1972e73) and IRS-P6 AWiFS (2006e07) considerable LULC changes are observed, an increase in crop-land and vegetated areas of w57% in the eastern and w68% in the western Rajasthan.

Purpose - The purpose of this paper is to assess the exposure of cooks in rural India (55 households) to the indoor air pollution levels emitted from burning of different fuels, i.e. cow dung, wood, liquefied petroleum gas (LPG) and propane natural gas(PNG) kerosene for cooking purposes. Design/methodology/approach - Indoor air quality was monitored during cooking hours in 55 rural households to estimate the emissions of PM10, PM2.5, CO, NO2, VOCs and polyaromatic hydrocarbons (PAHs).
