Asbjørn Aaheim Ranjith Gopalakrishnan Rajiv Kumar Chaturvedi N. H. Ravindranath Anitha D. Sagadevan Nitasha Sharma Taoyuan Wei 《Mitigation and Adaptation Strategies for Global Change》2011,16(2):229-245
We examine the potential for adaptation to climate change in Indian forests, and derive the macroeconomic implications of
forest impacts and adaptation in India. The study is conducted by integrating results from the dynamic global vegetation model
IBIS and the computable general equilibrium model GRACE-IN, which estimates macroeconomic implications for six zones of India.
By comparing a reference scenario without climate change with a climate impact scenario based on the IPCC A2-scenario, we
find major variations in the pattern of change across zones. Biomass stock increases in all zones but the Central zone. The
increase in biomass growth is smaller, and declines in one more zone, South zone, despite higher stock. In the four zones
with increases in biomass growth, harvest increases by only approximately 1/3 of the change in biomass growth. This is due
to two market effects of increased biomass growth. One is that an increase in biomass growth encourages more harvest given
other things being equal. The other is that more harvest leads to higher supply of timber, which lowers market prices. As
a result, also the rent on forested land decreases. The lower prices and rent discourage more harvest even though they may
induce higher demand, which increases the pressure on harvest. In a less perfect world than the model describes these two
effects may contribute to an increase in the risk of deforestation because of higher biomass growth. Furthermore, higher harvest
demands more labor and capital input in the forestry sector. Given total supply of labor and capital, this increases the cost
of production in all the other sectors, although very little indeed. Forestry dependent communities with declining biomass
growth may, however, experience local unemployment as a result. 相似文献

Water sustainability: reforming water management in new global era of climate change 总被引:1,自引:0,他引:1

The National Seminar on Sustainable Water Resource Management in Era of Changing Climate (NSWRM-2014) on 10–11 January 2014 organised by the Institute of Environment and Sustainable Development and Environmental Science and Technology, Banaras Hindu University, witnessed the presence of experts from environmentalists, industrialists and experts on water resources and its management. The deliberations and scientific discussions led to the conclusion that it is not just the resource but the natural capacity to sustain it that requires monitoring, understanding and stewardship. The focus of governance in India needs to move at a faster pace from conventional methods of sector-based water management to more integrated approach for sustainable water resource management. It is more of the people participation that is the future key towards sustainable water resource management in India. 相似文献

Heavy metal (Cu, Zn, Cd and Pb) contamination of vegetables in urban India: a case study in Varanasi 总被引:8,自引:0,他引:8
Sharma RK Agrawal M Marshall FM 《Environmental pollution (Barking, Essex : 1987)》2008,154(2):254-263
The contributions of heavy metals in selected vegetables through atmospheric deposition were quantified in an urban area of India. Deposition rate of Zn was recorded maximum followed by Cu, Cd and Pb. The concentrations of Zn and Cu were highest in Brassica oleracea, Cd in Abelmoschus esculentus and B. oleracea, while Pb was highest in Beta vulgaris. Heavy metal pollution index showed that B. oleracea was maximally contaminated with heavy metals followed by A. esculentus and then B. vulgaris. The results of washing showed that atmospheric deposition has contributed to the increased levels of heavy metals in vegetables. Both Cu and Cd posed health risk to local population via test vegetables consumption, whereas Pb posed the same only through B. oleracea. The study concludes that atmospheric depositions can elevate the levels of heavy metals in vegetables during marketing having potential health hazards to consumers. 相似文献

Effect of land use land cover change on soil erosion potential in an agricultural watershed 总被引:6,自引:0,他引:6

Universal soil loss equation (USLE) was used in conjunction with a geographic information system to determine the influence of land use and land cover change (LUCC) on soil erosion potential of a reservoir catchment during the period 1989 to 2004. Results showed that the mean soil erosion potential of the watershed was increased slightly from 12.11 t ha???1 year???1 in the year 1989 to 13.21 t ha???1 year???1 in the year 2004. Spatial analysis revealed that the disappearance of forest patches from relatively flat areas, increased in wasteland in steep slope, and intensification of cultivation practice in relatively more erosion-prone soil were the main factors contributing toward the increased soil erosion potential of the watershed during the study period. Results indicated that transition of other land use land cover (LUC) categories to cropland was the most detrimental to watershed in terms of soil loss while forest acted as the most effective barrier to soil loss. A p value of 0.5503 obtained for two-tailed paired t test between the mean erosion potential of microwatersheds in 1989 and 2004 also indicated towards a moderate change in soil erosion potential of the watershed over the studied period. This study revealed that the spatial location of LUC parcels with respect to terrain and associated soil properties should be an important consideration in soil erosion assessment process. 相似文献
