Smart Cities are defined in various ways by different people, but all have an underlying concept that being "smart" involves using information and communication technologies (ICT), the internet to address urban challenges. The rapid growth in use of computers, electronic devices and gadgets in today's urbanized world, leads to more production, consumption and generation of Waste Electrical or Electronic equipment (WEEE) or E-Waste. E-Waste is a hazardous waste, thus there is a challenge to manage it and its proper disposal. The authorized E-waste recycling facilities in India capture only 3% of total E-waste generated; the rest makes its way to informal recycling yards in major cities like Delhi, Mumbai and Bangalore. Ahmedabad is selected among the first 20 Smart Cities in India under the Smart Cities Mission, Ministry of Urban development (MOUD), Government of India (GOI). Ahmedabad also ranks sixth among the top ten Indian cities generating E-waste. The paper describes a study of the existing scenario of e-waste management; the level of awareness in the people for the disposal of e-waste by surveying the formal and informal sector, consumers/end-users, small and medium scale enterprises (SMEs) in the city of Ahmedabad. © 2017 ACM.

Renewable Energy | Year: 2017
Typical Meteorological Years (TMY) provide a basis for modeling solar photovoltaics. Their use, however, assumes continued historical norms inconsistent with climate change. Modifying TMYs with Regional Climate Models (RCMs) responds to this issue and has applications in renewable energy evaluations. This paper provides perspective on using modified TMYs for solar resource assessments, offers methodological improvements, and analyzes the impacts of insolation and irradiation changes on photovoltaic performance. For Ahmedabad, India, a TMY is constructed from Indian Meteorological Department measurements and modified with two Regional Climate Models - REGCM4 and REMO 2009. For each modified TMY and baseline, the performances of three photovoltaic technologies (monocrystalline, polycrystalline, and double-junction amorphous silicon) are considered for 2015–2050. Increases in ambient temperature are found to have small (<1.0%) but increasing negative impacts on monocrystalline and polycrystalline performance through 2050. A less significant positive trend (<0.1%) was observed for double-junction amorphous silicon. Insolation adjustments for REGCM4 were excluded after an error analysis. Insolation changes from REMO 2009 projected a 4% decrease in photovoltaic output by 2050, but should be considered cautiously given concerns over cloud modeling. A sensitivity analysis of monthly insolation modifications on photovoltaic performance revealed the relative impact of insolation changes in different months. © 2017 Elsevier Ltd

Megaprojects are becoming increasingly common in developing countries. In India, the need for and trend of rapid infrastructure development has resulted in design and implementation of projects of large scope and size, in terms of complexity and costs. As a result, megaprojects are being implemented in almost all infrastructure sectors in the country. The implementation of a megaproject attracts a lot of attention among the policy makers and researchers owing to their enormous economic, social and environmental impacts. The performance of megaprojects in terms of two key parameters - cost and time - is closely monitored by the Government of India, and this has resulted in the publication a set of reports to disclose information on project progress. Althoughquantitative analyses of the information available in these reports have been performed by the researchers, very few qualitative analysis reports are available. In this context, a qualitative research study has been undertaken in this work, to analyse the reasons for time and cost overrun in megaprojects. The analysis furthers the knowledge on megaprojects implementation by providing inference on not only key reasons for time and cost overruns but also factors and trajectories leading to the manifestation of a particular cause. The analysis indicates that delay in land acquisition, capability of contractors and contractual complexity were the major causes of time and cost overruns and these issues traverse through different layers - policy, institutional and project associated with megaprojects. The study findings are useful to policy makers to design interventions at these three layers for addressing the cause of time and cost overruns, and ensuring effective implementation of megaprojects. © The Authors, published by EDP Sciences, 2017.

This paper develops a conception of “sites of entitlement” as a basis for better understanding how infrastructure and services are perceived and experienced in informal settlements. While legal and policy frameworks are often viewed as the source of entitlements to infrastructure and services, the complexity of provision, access and negotiation in informal settlements demands a conception of entitlement that exceeds those domains. Based on ethnographic research on sanitation and water in informal settlements in Mumbai, we focus on the ways in which people’s everyday experiences, interactions and practices constitute sites of entitlement. These sites are unevenly produced, contested, often in flux and ambivalent, sometimes made through collective struggle and at other times through quiet individual practice, and always constituted by social relations. Sites of entitlement emerge in close relation to moral economies, and are characterized by often profound and – for research, policy and practice – challenging levels of spatial and temporal variation. We argue that sites of entitlement are vital for thinking through the possibilities of realizing the universal right to sanitation and water. © 2015, © 2015 International Institute for Environment and Development (IIED).

The global sanitation crisis is rapidly urbanizing, but how is sanitation produced and sustained in informal settlements? Although there are data available on aggregate statistics, relatively little is known about how sanitation is created, maintained, threatened, and contested within informal settlements. Drawing on an ethnography of two very different informal settlements in Mumbai, this study identifies key ways in which informal sanitation is produced, rendered vulnerable, and politicized. In particular, four informal urban sanitation processes are examined: patronage, self-managed processes, solidarity and exclusion, and open defecation. The article also considers the implications for a research agenda around informal urban sanitation, emphasizing in particular the potential of a comparative approach, and examines the possibilities for better sanitation conditions in Mumbai and beyond. © 2014 © 2014 by Association of American Geographers.

Earthquake Spectra | Year: 2010
Poor performance of reinforced concrete (RC) frame buildings in India during past earthquakes has been a matter of serious concern. Hence, it becomes important to identify and strengthen the deficient buildings. When dealing with a large building stock, one needs evaluation methods for quick assessment of the seismic safety of existing buildings so that corrective retrofitting measures may be undertaken on the deficient buildings. This paper presents a review of some of the available methods for rapid visual screening (RVS) of RC-frame buildings and proposes a RVS method for RC-frame buildings in India based on systematic studies on damage data of the 2001 Bhuj earthquake. © 2010, Earthquake Engineering Research Institute.

Transportation Research Part D: Transport and Environment | Year: 2016
Metropolitan areas around the world are looking for sustainable strategies to reduce use of private automobiles, energy consumption and emissions, often achieved by built environment interventions that encourage use of sustainable modes of transport. This study contributes by providing the empirical evidence on the relation between built environment and mode choice in context of Indian city of Rajkot. Using personal interview data and data available from Rajkot Municipal Corporation it is observed that there is a strong tendency among Rajkot residents to preselect their residential location to suit their modal preferences. This is especially true for non-motorized transport users. Among the built environment variables, access to destination and land use related indicators also have significant influence on mode choice. The study Infers that the land use policy should focus on accessibility and mixing of diverse uses, and transport supply will have to be location based to support non-motorized and public transport travel. © 2015 Elsevier Ltd.

Energy Procedia | Year: 2012
Energy consumption in the building sector is very high and it is expected to increase further due to increase in standards of living and change in typology of the building. Other major factor which has a significant effect on energy consumption is climate, especially in hot and dry climate. There is vast temperature fluctuation in such type of climate promoting greater use of air conditioning system, thus increasing energy consumption. The Study examines the energy conservation potential of the Passive Downdraft Evaporative Cooling (PDEC) technique for the commercial building sector in hot and dry region of Ahmedabad. The Study examines four different scenarios, 1) Conventional Case, 2) Envelope Design case 3) Energy Conservation Building Code (ECBC) Envelope Design case and 4) ECBC Envelope Design case with Evaporative Cooler (EC). Performance of all scenarios is measured through simulation software 'eQuest'. Simulation results are compared with actual building observations and comparative analysis is done in terms of Cooling load, Energy consumption, CO2 emissions and other co-benefits. The Research finding proves that Passive Downdraught Evaporative cooling technique offer real opportunity for improving indoor thermal comfort conditions in a building whilst reducing cooling load of air-conditioning systems, thereby reducing energy consumption and provides better indoor environment by providing 100% fresh, cool air into a space. The analysis confirms the advantage of such passive cooling strategy in hot dry climate of Ahmedabad. Further research also identifies the significance of the integrated architectural approach. Result of the each scenario with better envelope design and efficient cooling technique has shown significant energy conservation. The findings clearly suggest that while energy efficiency can be achieved through building regulations/codes and appropriate choice of materials/construction technology, but the potential for energy efficiency is much higher when such measures are integrated into the design philosophy and approach. The results can be used to estimate the energy conservation potential of such technique for wider application and also in developing recommendations to encourage the use of such passive cooling techniques. As commercial building floor area in Ahmadabad is projected to be double by 2035, there is a large potential to conserve the energy. Developing guidelines and action plan to promote such techniques will certainly help to reduce energy consumption, hence reducing GHG emissions. © 2012 The Authors.

Sub-grade soil stabilization is one of the primary and major processes in the construction of any highway. The aim of this research paper is to formulate a model based on Genetic Algorithm which can be used to predict variation in the values of CBR of the Sub-grade Soil with the addition of a specific percentage of Fly Ash. The input values for this study were those which directly affect the CBR values i.e., directly proportional to CBR. It includes Liquid Limit (LL), Plasticity Index (PI), Optimum Moisture Content (OMC) & Fraction of Fly Ash added (F.A in %).For analysis of stabilization of soil using fly ash, Evolver 5.7 an add-in software of excel is used. Properties used for analysis are Liquid Limit, Plastic Limit, Optimum Moisture Content and California Bearing Ratio. This model will help all types of agencies involved in road construction like NHAI, Infrastructure Developers and Construction Contracting Organizations to pre-determine the soil stabilization achieved due to fly ash for a particular type of sub-grade soil. © 2012 Published by Elsevier Ltd.

Education system is divided in to two classes: formal and informal. Formal education establishes the basis of theory and practical learning whereas informal education is largely self-learning, learning from real world projects. Generally science and technology streams require formal method of education. The social and related aspects can be taught through the other methods. Education is a media through which the foundation of the knowledge and skill is built. The statistics reveals the increase in the trend of the literate population. This may be accounted due to the level of urbanization and migration to the cities in search for the 'white-collar jobs'. As a result, a shift in the employment structure is observed from a primary sector to a secondary and tertiary sector. Thomas Friedman in his book 'The World is Flat' quotes the impact of globalization on adaptation of science and technology, the world has become large to tiny. One of the technologies to mention here is geospatial technology. With the advancement in the satellite remote sensing, geographical information system, global positioning system, the database management system has become important subject areas. The countries are accounting hugh budget on the space technology, which includes education, training and research. Today many developing countries do not have base maps, they are lacking in the systemic data and record keeping, which are essential for governance, decision making and other development purpose. There is no trained manpower available. There is no standard hardware and software identified. An imbalance is observed when the government is promoting the use of geospatial technology, there is no trained manpower nor the availability of the experts to review the accurateness of the spatial data developed. There are very few universities which impart the degree level education, there are very few trained faculty members who give standard education, there exists a lack of standard syllabus. On the other hand, the industry requires high skilled manpower, high experienced manpower. This is a low equilibrium situation. Since the need is enhancing day by day, the shortage of the skilled manpower is increasing, the need of the geomatics education emerges. This paper researches on the need assessment of the education in geospatial specialization. It emphasises on the challenges and issues prevail in geospatial education and in the specialized fields of remote sensing and GIS. This paper analyse the need assessment through all the three actors: government, geospatial industry and education institutions.
