Q

Bangkok’s Land Use Problems

A
  • The land on which Bangkok is situated is actually paddy field and so is more suitable for rice farming
  • However, the economic development of the country could not prevent the land from being used for residential, industrial, and commercial centres on a grand scale
  • As there is no effective control on land use in Bangkok, the urbanisation of Bangkok has brought a hapazard, chaotic pattern of land use
  • Bangkok never had an official city plan in operation
