India in its rapid growth of Urbanisation is concentrating more on infrastructure development and service delivery. The rapid development gets hampered as a result of the gaps in availability and delivery of basic infrastructure services like water, waste management etc. The field of inquiry is limited to the urban settlement of Thiruvananthapuram, the capital of Kerala state of India.This paper intends to focus on the management of naturally available resources, specifically water (blue) and vegetation (green) within the region of study, where co-existence, management and economic viability will ensure sustainability of all. The impacts of urban growth on the environment, its management and protection are complex and difficult to evaluate. For a sustainable urban development project, there should not be an interruption between the policy frameworks and decision making processes. Blue-Green Infrastructure (BGI) is an active approach to urban flood resilience, recognized globally and in international literature that capitalises on the benefits of working with urban green-spaces and naturalised water-flow.Existing global blue-green interventions may differ in density, size or the nature of the problem, goal; learning from these initiatives will be useful to Indian cities in creating BGI frameworks to address local problems and challenges.To investigate change in trends of land use, existing land use pattern, variation in land use pattern and the concentration of land use at city level (Thiruvananthapuram) would be analysed. A new development approach to brown field and green field which offers basic infrastructure, open spaces, sewage and solid waste management is required in emerging cities.BGI at times of disaster acts as a sponge or serves as a spillover space and establishes itself as a point of preservation of locally available flora and fauna. Hence it is high time that we focus our development policies into these tools and techniques which are environment friendly.
