Abstract:  By design, lush green manicured lawn spaces are resource intensive ecosystems that consistently require a range of material inputs such as fertilizers, water and pesticides. This disposition renders the lawn to be a contentious space. From a social aspect, lawns represent sites of aesthetic, recreation and community activities. From an ecological aspect, lawns represent sites of high N (nitrogen) retention and soil moisture that are known to influence nutrient cycling in these ecosystems which, in turn, determine the positive or negative environmental effect . The thesis aims to provide a broad evaluation of the urban turfgrass lawn in Bangalore that has remained unexplored from both social and ecological perspectives. The thesis investigates three specific dimensions of the socioecological lawn in Bangalore, namely a) lawn greenhouse gas emissions of nitrous oxide (N2O) b) lawn management practices and their influencing factors and c) social drivers of lawn production and consumption in gated residential establishments. Using both quantitative and qualitative methodologies, I evaluate the effect of lawn fertilizer application on N2O emissions. On ascertaining that lawn fertilizer emissions are significant, I proceed to explore whether they could be a concern in Bangalore by estimating an expected emissions range and studying the nature of lawn space transformation within a selected space and time frame. On discovering that lawn N2O emissions could be a potential environmental concern, I then proceed to study lawn spaces from two defining aspects : lawn management practices and social drivers. The former entails a characterization of lawn management practices across different establishments within the city to allow for an identification of opportunities to reduce the lawn’s N-impact. The latter allows for an insight into the deeper forces at work behind the design, installation and perpetuation of aesthetically pleasing lawn spaces within the particular context of the gated residential establishments.
