Benjakitti Forest Park

Benjakitti Park, an urban oasis in Bangkok, emerged from a former Tobacco factory site. It spans 720,000 sq.m, serving as an educational hub about ecology, hydrology, and the environment. This initiative retains 128,000 cu.m. of rainwater, generating 1,600 cu.m. clean water/day. Addressing floods and droughts with nature-based solutions acts as a “sponge”, employing bioremediation for purification. The park fosters a wildlife habitat, housing 360 tree species, and transforming swampland into a rich ecosystem. It incorporates sustainable techniques, reusing materials, and repurposing factory buildings for museums and sports centers. Accessible to all, it’s a sanctuary within Bangkok, fostering a diverse, nature-centric experience – a biodiverse classroom for city dwellers.
