Survey your neighbourhood and find out the various ways in which the land has been used (houses, shops, parks etc.). Talk to people who have been residing there for a long time and find out the land use pattern of your locality ten or twenty years ago. Compare it with the current scenario and write three differences. Also, analyse and write the causes of the changing land use pattern.
