In the past, people used rice fields and paddy to grow their crops and the different kinds of food. However, there are seasons where the crops will grow. Some crops cannot grow in weather conditions where there is no rain and some must only be grown in cold weather or some in hot weathers. Due to these conditions, the crops that are produced will not be constant and the amount of crops produced will be lesser. The amount of land also affects the amount of crops produced by the different farmers in a year. When using traditional farming, the soil is fertile. After a period of planting and growing crops, the nutrients would all be used up by the crops and hence, turning into a piece of infertile land. This piece of land has to be abandoned and the farmers will have to find another piece of land to plant their crops. After 7 years or so, the soil will then gain back its nutrients and the farmers would be able to come back to grow crops. That is the reason why farmers have to move from place to place. This is very troublesome as the farmers has many farming tools and crops to carry along with them wherever they go.

Something bad about the traditional farming is the constraint of land used for farming and housing. As farming takes up lots of land, often calculated in Hectares(H), many people are not able to find a suitable spot for them to plant their crops because there are too many farmers using up the land. In a small farm, a farmer practices intensive farming where a farmer uses a lot of inputs per unit area. In a larger farm, a farmers practices extensive farming where the farmer uses fewer input per unit area. There are also two types of farming. They are low-tech farming and high-tech farming. Low-tech farming is a form of farming used by people living on remote hill slopes. The people use farming tools to help them with their farming. One example is shifting cultivation. High-tech farming is a form of farming used by modern countries in the 21st century. The people use advanced machinery and computer technology to help them grow the crops. The crops produced by this type of farming is of good quality and first grade.

To keep up with the 21st century, Singapore has decided to adopt the use of high-tech farming to reduce the use of land while keeping the the traditional farming going. Singapore has adopted two types of high-tech farming. They are Hydroponics and Aeroponics. These two types of farming are intensively used by Singapore. The agrotechnological parks produce high-quality fruits, vegetables, plants and flowers. There are a few benefits after Singapore adopted high-tech farming. In the past, traditional farming takes up huge lands. Today, the farms have been replaced by housing estates and MRT lines. The total area of farmland has decreased rapidly. Secondly, by using high-tech farming, farmers in Singapore have been able to produce good quality products at a reasonable price for the consumers to purchase them. Thirdly, Singapore government aims to have 20 percent of the crops eaten by the locals to be grown locally. This can increase the self sufficiency and decrease the amount of crops imported from other countries.

To conclude, Singapore can just rely on high-tech farming to be self-sufficient. To increase the possibility of this, Singapore can employ more people to learn the skills of high-tech farming so that more crops could be produced with more people doing the job. Singapore can also build more agrotechnological farms so that more crops can be produced to feed Singapore's population.
