Secondly, under land management through land use planning, buildings can be built higher and closer together. Building high density buildings in Singapore allow for more space thus increasing land in Singapore and is an effective use of land and is a solution to land limitations in a small city like Singapore. This is both a solution and way that the Singapore government has successfully used to meet the rising demand for land.
In Singapore, examples of high density buildings are blocks of HDB flats in the residential towns. High rise and densely packed skyscrapers in the CBD area in Singapore due to lack of land in the city area is yet another example of the use of high density buildings to increase land in Singapore. Restaurants and shops can be found at the ground level and offices in most of the upper levels and residences in the remaining top levels. The 50-storey buildings at The Pinnacle @ Duxton are other examples of high density buildings in Singapore. The use of high density buildings is the most common way of maximizing the use of land space in urban areas. In this way, more residential flats are available to house a growing population and also more office space to accommodate expanding economic activities.
Thirdly, under land management through land use planning the Singapore government used soil-less farming (hydroponic farming) to increase land use in Singapore. Soil is not needed to grow vegetables, fruits and flowers. Modern technology and scientific knowledge are used to grow crops without using soil. Crops to be planted are housed in a specially designed environment. Crops are grown in troughs filled with nutrient solution. This method takes up little space because such troughs can be stacked one above the other. Hence, less land is needed thereby maximizing and increasing the existing land use.
