Cultural-ecological synergies: Traditional practices and biophysical systems in India’s agro-climatic regions

India’s diverse ago-climatic zones have fostered rich traditional knowledge systems intricately tied to local ecological conditions. This study examines the biophysical characteristics and indigenous practices across six major regions—North, North-East, East, South, West, and Central—highlighting how climate, soil, vegetation, and water resources shape region-specific traditions in farming, water management, handicrafts, and agroforestry. The rationale stems from growing concerns over the erosion of these systems due to modernization, urbanization, and climate change, which threaten both biodiversity and cultural heritage. Employing a combination of primary and secondary research, the study explores how traditional ecological knowledge contributes to environmental sustainability, economic resilience, and social cohesion. Region-wise analysis reveals that these practices are not only adaptive but also offer valuable insights for sustainable resource management. Findings indicate a progressive decline in traditional practices, with notable regional disparities in their resilience and revival. The study emphasizes the critical need for integrating traditional knowledge with modern science and policy frameworks. In conclusion, the research advocates for targeted policy interventions, community-based documentation, and participatory conservation efforts to safeguard India’s cultural and ecological wealth. Strengthening these traditional systems can significantly enhance sustainable development, climate adaptation, and rural livelihoods.
