As emissions from the use of fossil fuels remain the largest source of greenhouse gas emissions in the country, a massive restructuring of the energy sector is needed. This requires integrated planning across all sectors, and the harnessing of all low-carbon energy technologies and emission reduction mechanisms so that affordable and reliable energy is available to everyone during the process of transition and after achieving net zero. This article examines the future energy requirements and surveys a wide range of studies to make recommendations for policy formulation.","PeriodicalId":11194,"journal":{"name":"Current Science","volume":"21 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88217140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We quantified seagrass fragments from the gut as leaf, stem and rhizome, and identified leaf fragments up to genera level by their morphological features and epidermal cell characteristics using an inverted microscope. The overall abundance of above-ground fragments (leaf, stem) was higher in all samples , which may suggest the dugongs use a cropping mechanism to forage. The ingested seagrass generic diversity was higher in Tamil Nadu ( n = 5) dugong individuals than those in Gujarat ( n = 2). A total of five genera were recorded from all samples, viz. Halophila spp., Halodule spp., Cymodocea spp., Enhalus sp. and Syringodium spp. In Tamil Nadu, Cymodocea spp. (46.24%) was the most dominant, followed by Halophila spp. (26.49%), Syringodium spp. (14.83%) and Halodule spp. (12.16%), with a low occurrence of Enhalus spp. (0.19%).

Such policies are relevant in India, where groundwater depletion may have severe implications at various socio-economic levels. In this study, using mathematical modelling, we assess the feasibility of two alternative irrigation water pricing policies – (i) uniform water pricing policy and (ii) differentiated water pricing policy, wherein farmers growing less water-requiring crops (<4488 m 3 /ha) get an incentive for saving water, while those growing water-intensive crops pay for it. Using a case study of Punjab, the breadbasket and one of the fastest groundwater-depleting states in India, alternative cropping patterns are also suggested. The findings reveal that the current rate of groundwater withdrawal could not sustain agricultural intensification in the state. Although optimization of resource allocation has the potential to save water by 8%, this alone is unlikely to break the rice–wheat mono-cropping pattern in Punjab. The analysis of two different volumetric irrigation water pricing policies shows that differentiated water pricing would be more effective in halting groundwater depletion in the state. However, adequate investment in irrigation water supply infrastructure, mainly for installing water meters, is required to implement the policy.","PeriodicalId":11194,"journal":{"name":"Current Science","volume":"51 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89559069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The submerged parts and scattered destruction remains have been identified in onshore and offshore excavations around the coastal lines of the Bay of Bengal in Tamil Nadu. Information on the port city can be found in various sources, such as archaeological evidence, historical references, coastal erosion data and Sangam Tamil literature.

The findings show that the average real cost during 2017–18 to 2020–21 declined, leading to an increase in the net return to cost ratio from farming. Technological interventions at the farmer’s field resulted in a gradual decline in the share of seed, fertilizer and plant protection chemicals in the cost of cultivation. The price elasticity of factors, estimated by fitting the translog function, suggests that policies for controlling input price inflation, particularly wage rate, will be imperative in reducing the cost of farming. The results on the elasticity of technical substitution between labour and machinery highlight the need for devising suitable farm mechanization strategies which may be affordable in the small farm situation as well. The panel data estimate of negative cost elasticity of yield indicates that productivity growth plays a vital role in absorbing the increase in production cost.","PeriodicalId":11194,"journal":{"name":"Current Science","volume":"6 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90636348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
