Langkawi's development until the year 2005 / 2006 is spelt out in the Langkawi Development Plan (1990-2005 / 2006). With a population projected to grow to 100,000 by the year 2005 / 2006, the strategy is a combination between inland development such as providing new facilities, and preserving the development of the coastal area.

The entire plan is centred on preserving the environment, as tourism continues to lead as the island's key economic sector.

In 1990, the Federal Government set up the Langkawi Development Authority (LADA) to develop the island as a tourist destination, as well as to improve the socio-economic standard of the local people.

LADA's responsibilities cover improvements in water and electricity supply infrastructure, road networks, airport facilities, housing, and tourist attractions.

The airport has been expanded three times within the decade, and a new harbour is taking shape.
