Economic impacts of climate change on secondary activities: a literature review
No full textThe fast growing literature on economic impacts of climate change is inclined to assessing the impacts on agricultural production and productivity and on human health. The economic impacts of climate change however, go beyond these sectors. In this paper, we attempted to review the scarcely available literature on the economic impacts of the change in the climate of the earth on some selected non-agricultural secondary and tertiary level of economic activities. It is at-tempted to summarize the ways through which the climate change can affect non-agriculture economic activities. The discussion on the literature can be synthesized as showing the impacts on secondary and tertiary level of economic activities are wide and complex and eventually may be larger than on the impacts on agriculture for those middle and high-income countries where the share of agriculture in national GDP is low.This article is available at http://dx.doi.org/10.4236/lce.2012.3200

Is India on a Sustainable Development Path?
Get PDFSustainability requires that the productive base measured in terms of comprehensive wealth of a society should be increasing on per capita basis. Comprehensive wealth includes manufactured, human and natural capital along with knowledge base and institutions. This study offers methodological improvements and provides estimates of the growth rate of per capita comprehensive wealth over the period 1970-2006 for Indian economy. It considers air, water and soil degradation along with energy, minerals and forests depletion. To measure the value and composition of investment in natural capital, it estimates resource depreciation allowances on the basis of Hotelling rent; it adjusts education expenditure for depreciation in human capital; and uses the estimates of TFP that takes into account natural capital in the production of commodities and services. The empirical application suggests that Indian economy is barely sustainable. Growth rate of per capita comprehensive wealth was virtually near zero, it was only 0.15 percent per year for the study period. The growth rate was negative till 1983. Thereafter it became positive; however it was less than one percent in 1980s and 1990s. In recent years the growth rate was about 4 percent. Despite certain limitations, the study underscores the need for vigorous public policies that help in preventing excessive resource depletion and promoting higher genuine investment.Sustainability, development, Comprehensive wealth, Hotelling rent, India
Resource use efficiency of US electricity generating plants during the SO2 trading regime: A distance function approach.
Get PDFThis paper measures resource use efficiency of electricity generating plants in the United States under the SO2 trading regime. Resource use efficiency is defined as the product of technical efficiency and environmental efficiency, where the latter is the ratio of good output (electricity) to bad output (SO2) with reference to the best practice firm, i.e., one that is producing an optimal mix of good and bad outputs. This concept of environmental efficiency is similar to that of output oriented allocative efficiency. Using output distance functions we compare three methods for the calculation of resource use efficiency, namely, stochastic frontier analysis (SFA), deterministic parametric programming and nonparametric linear programming. This paper reveals the strengths and weaknesses of these methods for estimating efficiency. Both SFA and linear programming approaches can estimate the efficiency scores. For plants in the dataset the overall geometric mean of the three methods for technical efficiency, environmental efficiency and resource use efficiency is 0.737, 0.335 and 0.248, respectively. The rank correlation coefficient between technical efficiency, environmental efficiency and resource use efficiency is 0.213, 0.617 and 0.877, respectively. The regression analyses of performance across plants shows units in phase I of the SO2 trading programme are negatively related to measures of economic and environmental performance. This suggests that the market for SO2 allowances, per se, may not be minimizing compliance cost. We also find that a decrease in SO2 emission rates not only increases environmental efficiency but also leads to an increase in resource use efficiency. This finding concurs with the hypothesis that enhancement in the environmental performance of a firm leads to an increase in its overall efficiency of resource use as well.Technical efficiency ; Environmental efficiency ; Resource-use efficiency ; Distance functions ; SO2 allowance program
Impact of Rice Husk Ash on Cement Concrete
No full textImpact of rice husk fiery debris on cement concrete is a lab give an account of cement concrete is that the consuming of rice husks RH has made a high pozzolanic reactivity and property. Indian standard code of practice for reinforced concrete and plain is 456 2000, prescribes utilization of rice husk fiery remains is influenced in the ignition and the temperature. The report clarifies about the entire photo of the lab report with rate esteem. Rice Husk Ash contains silica in undefined and profoundly cell frame, with 50 1000 m2 g surface zone. In this way, the utilization of rice husk fiery debris cement dealing with and enhanced strength, lessen the heat generation, thermal cracking and plastic shrinkage. This builds quality impermeability, improvement and toughness by reinforcing progress zone, changing the pore structure, obstructing the huge voids in the hydrated cement glue through pozzolanic response. Rice husk cinder limits antacid aggregate response, decreases development, shines pore structure and thwarts dissemination of soluble base particles to the surface of aggregate by micro porous structure.

Measurement of environmental efficiency and productivity: A cross country analysis.
Get PDFThis paper measures environmental efficiency (EE) and environmental productivity (EP) and analyses differences in these across countries. It explores the macroeconomic factors that could explain these differences and whether these differences can be explained by income levels and by the degree of openness in these countries. The EE index is found to be almost steady over the period 1971-92 for the annex-I countries, while its value is declining for non-annex-I countries over this period. The EP index increased over this period in both groups of countries. In the annex-I countries, EE exhibits an inverted `U' shape with respect to per capita income while it is `U' shaped for the non-annex-I countries. This study also finds that while the EP index increases with income in annex-I countries it is decreasing in the non-annex-I countries. The degree of openness has a significant negative impact on EE and EP in both groups of countries.Environmental efficiency ; Environmental productivity ; Distance function ; Per capita income ; Openness
Non-separability and substitutability among water pollutants : evidence from India
Get PDFThe design and implementation of environmental policy often involve more than one pollutant, and must consider pollution as a byproduct of the production of marketable output. In this paper, we test the implicit assumption in the empirical literature that (1) production of marketable output, pollution and abatement are separable, and (2) different pollutants can be abated separately. Using unique plant-level data in India, we reject the null hypotheses of separability between marketable output and pollutants, and between different pollutants. Firms must incur abatement costs for reducing pollution levels. In addition, complement and substitute relationships between water pollutants are demonstrated with statistical significance. \u
