Measuring Disparity in the Distribution of ROS in Adolescents Using Geospatial Analysis

Abstract

Recreational open spaces (ROS), as essential public amenities, provide a multitude of benefits for city residents. The rapid growth of urban population is raising significant concerns about diminishing green infrastructure, shifts in land use, and erosion of valuable ecosystem services. This necessitates the equitable allocation of green infrastructure in appropriate proximity to the city residents. This study assessed disparity in ROS distribution, considering both availability and accessibility at varying administrative levels. The distribution is assessed with respect to resident population, providing special regard to the adolescent age group. Study is conducted taking Bhopal, India as the case. The Green Space Index and the Lorenz curve are utilized to assess social equity of ROS distribution. In addition, location quotient is employed to assess spatial equity concerning ROS distribution with respect to distribution of resident population. The study outcome illustrates that urban park accessibility varies at different administrative levels. Analysis reveals that higher number of ROS do not necessarily translate to higher ROS accessibility, especially for the adolescent age group. This is due to the inadequate size and proximity of ROS to residents, particularly in recent developments. A participatory GIS survey of 651 adolescents is conducted to further confirm the preceding spatial analyses by exploring associations between ROS accessibility and adolescents ROS visits. The prevailing urban ROS planning in India and several developing nations primarily relies on per capita availability and ratios of ROS to developed land. This approach alone is insufficient. The study results hold vital implications and can be incorporated in the existing urban ROS guidelines. This analysis is pivotal for sustainable ROS planning and policy-making, aiming to achieve environmental and social sustainability, centered on population, especially adolescents. This study centers on assessing the spatial allocation of ROS with a focus on equity considerations. The particular emphasis lies in examining how well the spatial distribution of ROS aligns with the requirements of its population in the same planning region. The outcomes of this investigation reveal that the conventional metrics used in ROS planning, namely the per capita ROS area and ratio of ROS to urban land, do not adequately capture the equity dimensions of ROS provision. The results reveal that spatial misalignment exists in the allocation of ROS and its distribution among the population, especially among adolescents. Furthermore, the results highlight that urban growth and densification can result in a general decline in urban green infrastructure. Such results will help to implement green initiatives across identified administrative levels to enhance the wellbeing of residents with an understanding of the population distribution within a region.
