Tanka: Water Harvesting System of the Parsi Community

This insightful talk explores the deep spiritual and cultural relationship between water, sustainability, and traditional ecological knowledge in India and Zoroastrian communities. Addressing the growing global water crisis, the speaker explains how ancient water conservation systems such as Iran’s qanat technology and India’s tanka rainwater harvesting methods provided sustainable, community-based solutions for centuries.

The presentation highlights how water has long been regarded as sacred — not merely a resource, but life itself. Drawing connections between Indigenous wisdom, environmental stewardship, and modern sustainability challenges, the speaker reflects on how colonial systems disrupted local water traditions and increased dependence on centralized infrastructure.

Through detailed explanations of traditional rainwater harvesting design, filtration systems, and community resilience, the talk demonstrates how ancient practices can still offer practical solutions for modern environmental challenges. It also emphasizes the importance of reviving ecological knowledge, adapting architecture for sustainability, and encouraging public participation in water conservation efforts.
