Unsustainable Transformation Resulting from Migration and Unbalanced Regional Growth

-

Research Paper

In developing countries most of the development and investment happens in few concentrated urban areas only, leaving other settlements to lag behind in terms of economic growth. It is evident that urban areas attract people for more economic prosperity resulting in higher quality of life. But it is also accompanied by major social and economic inequality.

Application of Space Syntax, Space Matrix and Mixed Use Index for Property Tax Assessment Using GIS in T. Nagar, Chennai - Bachelor’s Thesis The fundamental challenge of infrastructure development is financing. Except few large scale ULBs, most of the small and medium scale ULBs have deficit municipal finance, low credit rating, insufficient human resource and technical capabilities. Resulting in high dependency of ULBs on State & Centre for financial outlays. The opportunity of Property Tax (own revenue stream) of ULBs is explored in the paper. This result is a dynamic map which as potential to demarcate property tax assessment zones at street level within the ward and determine the base rates for each zone. The outcome of research is a rational spatial property tax assessment method through application of GIS in the proposed Smart City Area.

Developing CityGML based 3D Urban Models using UAV for Smart Cities of India - Project work at IIRS (ISRO) CityGML is designed as an open data model and XML-based format for the storage and exchange of virtual 3D city models. The study’s aim was integrating AMRUT and SCM utilizing the current technologies of Unmanned Aerial Vehicle (UAV). The UAV derived orthoimage and point cloud in conjunction with 2D GIS Master Plans of AMRUT can integrated to build rich 3D Spatial Information Model. The developed workflow is automated for 2D spatial layer extractions and transformation into 3D Cesium Tile format. The 3D CityGML Model incorporates extensive information of the buildings, utility network, transportation, vegetation and other features. The Cesium Tile format can be effectively hosted in web based applications & interactive models for visualization, analytics and decision-making.

AI for Water Work at SmartTerra

AI powered Water Analytics Platform for Bangalore: All the major Indian Cities are at the tipping point of Water Crisis. It is expected to worsen more, as 416 million population would be added in urban areas by 2050. Traditional Water Planning and Management systems used by the Government and Municipal Bodies are not able to support decision-makers. I was part of building AI cloud hosted tool to achieve Equitable Municipal Drinking Water Supply, to improve operations and cost-recovery, to reduce commercial loss and to balance demand/supply for Bangalore. I work on the machine learning model for predicting Consumption, Leakage, meter bye-pass, meter degradation, spatial outliers detection using Python and QGIS.

Regional Development Plan Studio (District Level) Wayanad District, Kerala - Bachelor’s Sem 7 Wayanad is the most hunted tourism destination in Kerala. It was once a agrarian district with predominant cultivation of paddy. But due to low income & price fluctuation, the cultivators have shifted to cash crops such as coffee, banana, ginger, tapioca, arecanut, etc. This shift in crops has resulted in food security issues, environmental degradation, health issues, subject to global price fluctuations and risks Page 17 to 23 resulting in suicide of farmers. Hence a major focus was given on the agriculture sector to develop food sufficiency and to increase the per capita income of the population in Wayanad through multiple cropping mode l(food and cash)

Action Plan (IIT Bombay Competition) Uppada Village, Andhra Pradesh Uppada is a small village of 3632 population. There are two communities based on fishing & silk weaving. The silk weaving technique practiced in the village is of ancient origin called the Jamdani. It have been granted the Geographical Indication (GI) registration in India.

But, the tradition of inheriting the ancient skill is diminishing due to low returns, digital markets, mechanization and diversification of Page 25 to 27 occupation. A cultural centre with tourism circuit is developed to promote social and economic development and to sustain the traditional weaving practice in the village. I was the Team Leader heading 7 people. The team was selected as Top 10 teams in the competition.

My contributions were in problem identification, proposal and concept formulation.

Thinking Trash – Business Plan for Public Infrastructure – NOSPLAN (2017) - Competition Work The major problem with the Indian cities is that the amount of unsegregated waste at household adds enormous costs to the ULB making it impossible to recover money by recycling waste. Vijayawada is not an exception. The business plan proposed tries to achieve a state of optimum utilization and management of the municipal solid wastes through incentivizing households. The business plan paces forward to earn and recover solely through the wastes produced without user charges and interestingly paying back to the residents through non tangible monetary benefits.

I was the Team Leader heading four members. The team won First National Prize - Business Plan for Public Infrastructure event in NOSPLAN, 2017. The same team headed by me was the runner for Data Visualization event of NOSPLAN 2017

Local Area Development Plan (Ward Level) Odhav, Ahmedabad

-

Bachelor’s Sem 3

Odhav is an residential cum industrial neighborhood in the city of Ahmedabad. Over the years, the landuse and infrastructure facilities have been degraded. Therefore a local area plan was prepared after analyzing various sectors such as demography, housing, landuse, physical and social infrastructure, industries and environment.

My contribution was in the demography and landuse sector of Odhav. I was also involved in the selection of case area for the studio.
