Agriculture is multi-functional, producing economic goods including food, feed, fibre, and fuel, as well as providing several intangible or non-tradable services to society free of cost. Non-tradable services, unlike economic goods, remain unpriced; as a result, farmers are not compensated monetarily for the benefits of the several non-tradable services they …
The fields of climate change and livestock research have not always been cosy bedfellows. But they are ironing out their difficulties and looking ahead.
Previous studies have suggested that diabetes mellitus (DM) is an outcome of exposure to air pollution, and metabolic detoxification genes affect air pollution–related outcomes. The researchers evaluated associations between air pollutants and markers of insulin resistance (IR), an underlying mechanism of type 2 DM, and effect modification by GSTM1, GSTT1, …
Evaluating the net exchange of greenhouse gas (GHG) emissions in conjunction with soil carbon sequestration may give a comprehensive insight on the role of agricultural production in global warming. Measured data of methane (CH4) and nitrous oxide (N2O) were utilized to test the applicability of the Denitrification and Decomposition (DNDC) …
MUMBAI: Bumper-to-bumper traffic in Mumbai is not only pushing up citizens' frustration levels, it is also increasing vehicular emissions on key routes in the city by 33% to 75% during peak traffic hours. A study prepared by the National Environmental Engineering Research Institute (NEERI) which will be released on Thursday …
Environment Ship Index (ESI) has shown a steady growth of ships whose emissions are lower than the internationally allowed limits. At the end of June, 1089 ships had a score on the Environment Ship Index (ESI) as against start of this year, when there were only 570 ships. Thirty-five per …
The umpteenth efforts taken up by the Delhi Government in making the city pollution free have come to a nought as the air in national Capital is fast becoming poisonous with the increasing level of Suspended Particulate Matter (SPM) and Nitrogen Oxide. This is due to rapid growth of diesel-run …
Driven by rapid economic development and growing electricity demand, NOx emissions (E) from the power sector in India have increased dramatically since the mid-1990s. In this study, we present the NOx emissions from Indian public thermal power plants for the period 1996–2010 using a unit-based methodology and compare the emission …
The paper presents the nature of annual cycles of tropospheric ozone, cloud occurrences, NO2, rainfall, SO2, SPM, CO, non-methane hydrocarbon and surface solar radiation for the period October 2004 to June 2009 over Alipore (22.52°N, 88.33°E), India. Annual cycle of low-level cloud occurrences depicts that the low-level cloud over Alipore …
The study was carried out during the months of March-May, 2012 to see the status of air quality by monitoring and assessment of some selected air pollutants namely Respirable Particulate Matter (RSPM or PM10), Fine Particulates (PM2.5), Sulphur dioxide(SO2), Nitrogen dioxide (NO2), and Trace metals- Iron (Fe ), Nickel (Ni), …
Fossil fuel combustion and fertilizer application in the United States have substantially altered the nitrogen cycle, with serious effects on climate change. The climate effects can be short-lived, by impacting the chemistry of the atmosphere, or long-lived, by altering ecosystem greenhouse gas fluxes. Here we develop a coherent framework for …
The atmospheric nitrous oxide mixing ratio has increased by 20% since 1750. Given that nitrous oxide is both a long-lived greenhouse gas and a stratospheric ozone-depleting substance, this increase is of global concern. However, the magnitude and geographic distribution of nitrous oxide sources, and how they have changed over time, …
Data on surface ozone concentration compiled for a 10-year period from 1990 to 1999 for Pune and Delhi are analyzed in terms of its frequency distribution, annual trend, diurnal variation and its relation with various meteorological and chemical parameters. It is found that the surface ozone concentration range showing highest …
The municipal solid waste (MSW) generated from different activities from various localities and a township in city areas is subject of deep concern for its proper management. The improper management of MSW is a major cause of air pollution. Present research deals with air quality parameter like SPM, RSPM, SO2 …
The present study deals with the effect of urbanization and automobile emission on ambient air quality of Bhubaneswar city, Odisha. This paper examines the significant difference in seasonal variations of air pollutant concentrations in the city.
The Department of Environment (DoE) yesterday fined Tk 12 lakh to a factory in Gazipur and a developer in the city's Dhanmondi area for air and noise pollutions respectively. A DoE team headed by Director (enforcement) Munir Chowdhury fined Radiant Renewable Energy Limited Tk 10 lakh at Mirzapur in Gazipur …
This report highlights a problem currently being experienced by new Euro IV and V heavy-duty trucks and buses: Despite meeting more stringent regulatory standards for exhaust emissions during type approval, many vehicles equipped with selective catalytic reduction (SCR) systems have significantly elevated emissions of nitrogen oxides (NOx) during in-use driving, …
The depiction of farming's greenhouse-gas footprint (estimated at 30.9% of total emissions) is derived from a 2007 report that used data from 2004 (Nature 479, 279; 2011). But relative estimates of emissions from different sources have altered appreciably since then, largely because fossil-fuel usage and cement production for building have …
New Delhi: After the early 2000s, when Delhi’s air became dramatically clean after the introduction of CNG in public transport, it has once again turned into a deadly cocktail of various pollutants. High levels of particulate matter (PM) that fired the original ‘clean air’ campaign 15 years ago, are no …
NEW DELHI: The Environment and Forests Ministry may stop halting industrial and government projects for minor lapses of conditions stipulated under the Environment (Protection) Act to escape the blame of slowing down the economic progress. For instance big dumps built up around the mining areas, pollution of nearby rivers and …
