This research paper examines the land economic development strategies in South Delhi, focusing on their impact on the socio-economic and spatial dynamics of the region. South Delhi, a diverse and economically vibrant district within the National Capital Region of India, presents a unique case study to explore how tailored land use policies and economic planning can foster sustainable growth. Using a mixed-method approach, this study integrates qualitative analysis of policy documents, stakeholder interviews, and quantitative assessment of economic indicators to analyze land use changes, economic transformations, and policy effectiveness from 2011 to 2021. The analysis spans both macro and micro levels, investigating transformations in key areas like Mehrauli, Lado Sarai, and Aya Nagar. Findings highlight significant shifts in land use from agricultural to residential and commercial purposes, driven by rapid urbanization, infrastructure development, and policy reforms. While certain strategies have effectively promoted economic growth, challenges such as environmental degradation, congestion, uneven policy enforcement, and socio- economic disparities persist. The study underscores the need for sustainable land use planning, improved infrastructure, stakeholder collaboration, and adaptive governance frameworks to balance economic growth with social equity and environmental sustainability The research offers comprehensive insights and practical recommendations for policymakers, urban planners, and stakeholders to optimize land economic development strategies in South Delhi, with implications for similar urban contexts globally. The study advocates for a holistic approach that integrates sustainable development, community engagement, and resilient policy frameworks to create livable and prosperous urban environments.
