Abstract

We are living in an uncertain world, reeling under extreme events of weather conditions, mal distribution of resources, global spread of highly infectious diseases, and inequitable access to services. Even small careless decisions may lead to uncontrolled human trauma. In such situations information system and classified help may reduce miseries to a great extent. The paper primarily analyses the illness profile of migrants and non-migrants and then relate them to the spatial accessible choices of the respondents in the Sub cities of Delhi by using GIS component for chronic and acute health needs. The objective of the spatial analysis was to find the spatial accessibility difference by types of illness, migration status. Methodology-Cluster sampling method was implemented, and a multi-stage design was considered to draw random sample for the selection of respondents from the urban villages and other neighbouring residential localities in the three sub-cities of Delhi. Duration of stay in Delhi was decided to determine the migration status. To micro-level spatial analysis geo-referencing was done by Trimble, by taking the approximate centre of the villages. However, each house was not georeferenced assuming that the difference in the distance from the home and the health centre would not vary beyond five hundred meters and will be cost effective also. Conclusion- Unbridled urban sprawl makes the accessibility issue more complex and researchable for a better health and urban planning. The vulnerable groups such as migrants and people living in fringe area are the worst affected due to accessibility and affordability. The paper concludes that the diseases such as diabetes, different types of cancer, coronary heart disease and injuries have close correlation with the urban planning and accessibility issues. The paper also finds that the poor migrants living at the margins in the planners’ perspective does not get any attention towards the increased cases of diabetes, injuries (includes fall) and vector born disease, water born disease due to poor urban planning reasons.
