Traditional Indian ecological wisdom embodied in Vedic Paryavarana, Ayurvedic resource management, johad/baoli water harvesting, paramparagat krishi, Vastu Shastra architecture, and Vriksh ayurveda presents actionable pathways to the UN Sustainable Development Goals. This study systematically maps these indigenous practices against environmental sustainability targets, analysing NITI Aayog's 2023-24 SDG India Index across eleven states (Top 10 states + Delhi), where Kerala and Uttarakhand achieve composite scores of 79, surpassing lower-performing eastern states. Using mixed-method analysis ESE pillar regression (R² = 0.82, βEnv = 0.42, p < 0.001), scheme adoption correlations (r=0.68), disparity indices, and synthesis of 25+ peer-reviewed studies, the study shows that Kerala has AYUSH jathas operating as a driver of SDG 3 (85) and Uttarakhand has sacred groves as a driver of SDG 15 (88) and Sikkim has organic agriculture as a driver of SDG 2 (global On the other hand, the Eurocentric biases in SDG schemes and the limited curricular coverage of NEP 2020 (less than 15 percent institutions) both weaken the adoption of IKS, especially in the demonstrated structural failures in Bihar. Indicative of fundamental queries of IKS-SDG compatibility, policy assimilation mechanisms and paradigmatic issues to Western models of sustainability, the findings recommend obligatory Vrikshayurveda curricula and community jatha pilots under NEP 2025 execution. The analysis makes the high-performing states the replicable examples of Prithvi-Samvardhana (earth preservation) implemented as cultural heritage instead of policy imperative in the role of guiding India to sustainability leadership in 2030.
