India is perceived to be one of the most attractive Non-Annex I countries for CDM project development. There are more than
350 projects in the CDM pipeline, largely in the areas of renewable energy, energy efficiency in industries and fossil fuel
switching. This paper examines the socio-economic component of sustainable development commitments of the CDM projects to
see if they can make any impact on rural poverty in India, since the goal of poverty alleviation lies at the core of the country’s
development priorities. The study concludes that CDM is not contributing to rural poverty alleviation to any notable extent.
Nearly all the projects have a business orientation and are not directed to the development of rural poor. Even the renewable
energy projects will have limited role in up-liftment of the masses below poverty line due to their weak resource base. For
CDM to emerge as a “win–win” strategy for poverty alleviation projects should be aimed at the rural communities and designed
to accelerate agricultural growth in the rainfed regions of the country. 相似文献

A chemical factory near Ranipet town in Vellore district, in the state of Tamil Nadu, India produced chromium-based inorganic
chemicals. The factory area in granite gnessic terrain receives an average annual rainfall of 1,000 mm. About 1.5 lakh tons
of solid wastes rich in hexavalent chromium (Cr6+), spreading over an area of 14,000 m2 (about 3.5 acres), having about 4 m thickness, is accumulated in an open yard within the factory premises. The soil and groundwater
in and around the factory area are contaminated with Cr6+ leached from dump site. Cr6+ is carcinogenic in nature and when leached in water can lead to respiratory disorders. Resistivity surveys comprising vertical
electrical sounding, multielectrode resistivity imaging, drilling of bore wells, chemical analysis of soil, formation and
groundwater samples and bore hole tracer studies were carried out within the factory and adjoining areas to decipher subsurface
geology, hydraulic behavior of dyke as natural barrier and lateral and vertical extent of pollution zone in and around the
chromium dump site. The data obtained were integrated and interpreted for understanding the pollution migration and its impact
on environment. Remedial measures are suggested for containing the contamination. 相似文献

Climate change poses formidable challenge to the development of livestock sector in India. The anticipated rise in temperature
between 2.3 and 4.8°C over the entire country together with increased precipitation resulting from climate change is likely
to aggravate the heat stress in dairy animals, adversely affecting their productive and reproductive performance, and hence
reducing the total area where high yielding dairy cattle can be economically reared. Given the vulnerability of India to rise
in sea level, the impact of increased intensity of extreme events on the livestock sector would be large and devastating for
the low-income rural areas. The predicted negative impact of climate change on Indian agriculture would also adversely affect
livestock production by aggravating the feed and fodder shortages. The livestock sector which will be a sufferer of climate
change is itself a large source of methane emissions, an important greenhouse gas. In India, although the emission rate per
animal is much lower than the developed countries, due to vast livestock population the total annual methane emissions are
about 9–10 Tg from enteric fermentation and animal wastes. 相似文献

Ethnic minority populations in Yunnan have had diverse mobility patterns since the advent of globalized production and developmental programmes. The article presents insights into the various mobility patterns and their effects in Yunnan and contributes to an understanding of the present economic and social processes of mobilities and changes in China as a whole. The analysis is based on an empirical study conducted in the years 2010–2011 by the authors together with local researchers in Yunnan. The results revealed that the mobilities practised among members of the ethnic minority groups in Yunnan included not only outmigration but also cross-border cultivation of plantations, daily and circular mobility, inflows of labour and investors, and involuntary relocation. Although some mobilities may have been conducive to livelihoods and capabilities due to the income-earning and profit-making opportunities arising from the acquisition and appropriation of land and capital, they have also resulted in differentiation processes that confirm the counter-geographies of production, survival, and profit-making. The authors conclude that mobilities do not just concern physical location, but as a social process, mobilities have reconstituted relational references and networks in terms of ethnic and cultural identity, gender relations, labour division, and locality and community integration. 相似文献

This paper presents the effect of geomagnetic storm on geomagnetic field components at Southern (Maitri) and Northern (Kiruna) Hemispheres. The Indian Antarctic Station Maitri is located at geom. long. 66.03° S; 53.21° E whereas Kiruna is located at geom. long. 67.52° N; 23.38° E. We have studied all the geomagnetic storms that occurred during winter season of the year 2004–2005. We observed that at Southern Hemisphere the variation is large as compared to the Northern Hemisphere. Geomagnetic field components vary when the interplanetary magnetic field is oriented in southward direction. Geomagnetic field components vary in the main phase of the ring current. Due to southward orientation of vertical component of IMF reconnection takes place all across the dayside that transports plasma and magnetic flux which create the geomagnetic field variation. 相似文献

A fluxgate digital magnetometer is used to study the variation of magnitude of H component during geomagnetic storm events of April, July and November 2004 at southern subauroral localized region at “MAITRI” (geom. lat. 62°S, long. 52.8°E). We also study the effect of vertical component of interplanetary magnetic field (IMF) on the variation of the magnitude of H component during storm time of April, July and November 2004. Results show that before sudden storm commencement (SSC) time magnitude of H component and IMF show smooth variation but after SSC of first storm of 22 July 2004, the magnitude of the H component shows fluctuations and at 09:00 UT it increases, but during second storm of 24 July 2004, the magnitude of H component indicates large fluctuations and it increases rapidly at 04:00 UT. 相似文献

The surface layers of the Bay of Bengal along the east coast of India exhibit intricate stratification owing to the differential
distribution of freshwaters. The winter (January–February) cooling of the salinity-induced stable layers results in the development
of thermal inversions that deteriorate toward the end of the season. The study focuses on the behavior of the thermal inversions
in the light of the variable stratification and the monsoon imposed reversing coastal current. To address the associated processes,
a three-dimensional Princeton Ocean Model is applied for the east coast of India, and numerical experiments carried out to
study the means by which the thermal inversions tend to perish with the passage of winter. The model domain with variable
curvilinear grid uses input fields that comprise realistic bathymetry and initial temperature/salinity conforming to winter/specified
stratification. The surface forcing comprises wind stress and diurnal pattern air–sea heat fluxes. The body forcing is derived
from the periodic tidal elevations at the open boundaries. It has been found that the thermal inversions tend to sustain as
the equator-ward flowing East India Coastal Current (EICC) traps the cool low saline waters between Paradip and Kakinada.
The current off Paradip is weak and variable and is not a part of EICC. Consequently, in the absence of replenishment of cool
and freshsurface waters, the temperature/salinity gradients get eroded steadily. No thermal inversions are noticed south of
Kakinada because of relatively weak current with diminished vertical salinity gradient. As the nature of stratification encountered
in the bay is highly variable due to diverse reasons, the behavior of internal waves under different stratification scenarios
is also addressed. Numerical experiments indicate that the energy/amplitude of the internal waves are comparable in the surface
layers for any stratification, where as it is certain orders exalted in the deeper waters of the strong stratification scenario.
Further, it is found that the energies and pattern of the temperature oscillations conform to the nature of mixed tide at
the corresponding latitude. The underneath stratification is found to be more responsible for the generation of internal waves compared to the local stratification. This implies that the body forcing emanating from below is the cardinal contributor for the generation of internal waves.
The numerical experiment with a flat and uniform bottom showing weak manifestation of internal waves endorses the same. This
connotes that the continental slopes are an effective generator of the internal waves and the energy flux conversion of the
barotropic tide to internal waves seems to be heavily dependent on the shoaling bottom. 相似文献

The purpose of this work is to investigate the effect of magnetic activity on ionospheric time delay at low latitude Station Bhopal (geom. lat. 23.2°N, geom. long. 77.6°E) using dual frequency (1575.42 and 1227.60 MHz) GPS measurements. Data from GSV4004A GPS Ionospheric Scintillation and TEC monitor (GISTM) have been chosen to study these effects. This paper presents the results of ionospheric time delay during quiet and disturbed days for the year 2005. Results show that maximum delay is observed during quiet days in equinoxial month while the delays of disturbed period are observed during the months of winter. We also study the ionospheric time delay during magnetic storm conditions for the same period. Results do not show any clear relationship either with the magnitude of the geomagnetic storm or with the main phase onset (MPO) of the storm. But most of the maximum ionospheric time delay variations are observed before the main phase onset (MPO) or sudden storm commencement (SSC) as compared to storm days. 相似文献
