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
Kharol S K, Kaskaoutis D G, Badarinath K V S, Sharma A R, Singh R P
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).
Impact of regulated pH on proto scale hydrogen production from xylose by an alkaline tolerant novel bacterial strain, Enterobacter cloacae DT-1
Subudhi S, Nayak T, Kumar N R, Vijayananth P, Lal B
A hydrogen producing facultative anaerobic alkaline tolerant novel bacterial strain was isolated from crude oil contaminated soil and identified as Enterobacter cloacae DT-1 based on 16S rRNA gene sequence analysis. DT-1 strain could utilize various carbon sources; glycerol, CMCellulose, glucose and xylose, which demonstrates that DT-1 has potential for hydrogen generation from renewable wastes. Batch fermentative studies were carried out for optimization of pH and Fe2+ concentration. DT-1 could generate hydrogen at wide range of pH (5-10) at 37 °C.

The objective of this paper is to analyse the data available in the glacier inventories published by Geological Survey of India and International Centre for Integrated Mountain Development and make a comparative assessment of the distribution and extent of Himalayan glaciers in the Ganges river system of Indian and Nepal Himalaya.Some interesting conclusions for this assessment were that majority of the estimated glacial ice volume towards the Ganges river system was from the Nepal Himalayas.

Algae are considered the most promising third-generation biofuel feedstock, because algae can grow on wasteland, wastewater, and waste gas. Thus, they do not compete with any resources needed for other useful purposes. Understanding how to engineer algae-to-biofuel systems is critical if we have to succeed in meeting our future transportation fuel demands. This chapter presents the engineering fundamentals of the algae-to-biofuel process and also draws attention to the challenges we must overcome.
