Takeaways
- 🌍 Major delta cities worldwide, including Bangkok, are sinking due to climate change.
- 🚧 Urbanization is transforming porous agricultural land into concrete jungles, reducing natural water absorption.
- 🌧️ Bangkok is sinking at an alarming rate of over one centimeter per year, four times faster than sea level rise predictions.
- 🏞️ The Centenary Park project aims to provide much-needed green space in Bangkok and combat flooding through innovative design.
- 🌱 The park features the largest green roof in Thailand, which collects rainwater for irrigation and promotes biodiversity.
- 💧 The park's design incorporates gravity to manage rainwater runoff effectively, channeling it to retention ponds.
- 🚴♂️ People can engage in activities like water biking, contributing to the park's water management while enjoying recreational space.
- 🌿 The concept of 'amphibious design' embraces flooding as a natural phenomenon rather than attempting to eliminate it.
- 🔍 Addressing climate change requires collaboration across various professions to develop sustainable urban solutions.
- ❤️ The Thai philosophy of 'tangjai' emphasizes commitment and perseverance towards goals, reflecting the speaker's dedication to their homeland.
