Delhi is a highly urbanized city in India. The rapid increase in population and unplanned development of infrastructure within the built-up environment is continuously damaging the urban and peri-urban green spaces of Delhi. Our modern indoor bound lifestyle is distancing us from the natural world. Through this paper, we have tried to review the possible contributions of both blue and green infrastructure on the urban environment and also on the wellbeing of the urban dweller. In continuation, this review article provides an interdisciplinary overview of the scientifically grounded knowledge on urban biodiversity and conservation, how it benefits urban ecosystems through their services, and finally integration of urban biodiversity into urban planning. At the outcome, knowledge gaps and opportunities for future research under the theme “Green Urbanism” has been critically reviewed.   Key words: Conservation, Ecosystem services, Human health, Urban Biodiversity, Urban green
