High tech farming is the key to food sustainability of Singapore.
This sentence summaries the high tech farming we have in Singapore.

Since 1986 AVA Singapore ( Agri-Food Veterinary Authority ) have stared for high tech farming because of limited agricultural land in Singapore. Hi-TECH Farming need less space, for more products, less manpower and more hygiene for better product Quality.Singapore need Modern Technology , since 1986, to day over 200 farms in over six Agrotechnology Parks all are " Hi-TECH " ,products from Milk,Vegetables,Fish,Eggs,Fruit,etc. .Those vegetables by Singapore from NTUC is from our hi tech farming.

High tech farming is a plausible alternative food source for Singapore but it is not possible to rely entirely on it. Singapore's small land size makes it difficult to accommodate large areas of land for farming, even for high tech farming, which requires less land area. Singapore still needs to import food from other countries to sustain the demand here, so importing food is still the only option.
