Parks and green zones

Bangkok has several parks, although these amount to a per capita total park area of only 1.82 square metres (19.6 sq ft) in the city proper. Total green space for the entire city is moderate, at 11.8 square metres (127 sq ft) per person. In the more densely built-up areas of the city these numbers are as low as 1.73 and 0.72 square metres (18.6 and 7.8 sq ft) per person. More recent numbers claim that there is 3.3 square metres (36 sq ft) of green space per person, compared to an average of 39 square metres (420 sq ft) in other cities across Asia. In Europe, London has 33.4 m of green space per head. Bangkokians thus have 10 times less green space than is standard in the region's urban areas. Green belt areas include about 700 square kilometres (270 sq mi) of rice paddies and orchards on the eastern and western edges of the city, although their primary purpose is to serve as flood detention basins rather than to limit urban expansion. Bang Kachao, a 20-square-kilometre (7.7 sq mi) conservation area on an oxbow of the Chao Phraya, lies just across the southern riverbank districts, in Samut Prakan province. A master development plan has been proposed to increase total park area to 4 square metres (43 sq ft) per person.

One of Bangkok's largest parks is the centrally located Lumphini Park near the Silom–Sathon business district with an area of 57.6 hectares (142 acres). It is connected by a 1.3 km elevated pedestrian and bicycle walkway to the Benjakitti Park, which includes a recently completed expansion including wetlands, skywalks and rare plants. Other parks include the 80-hectare (200-acre) Suanluang Rama IX in the east of the city, and the Chatuchak – Queen Sirikit – Wachirabenchathat park complex in northern Bangkok, which has a combined area of 92 hectares (230 acres). More parks are expected to be created through the Green Bangkok 2030 project, which aims to leave the city with 10 square metres (110 sq ft) of green space per person, including 30% of the city having tree cover.
