Using a custom-designed, modular hydroponic system, Citiponics can grow up to 25 different kinds of leafy vegetables and herbs without pesticides. According to Chan, the 1,800 square meter (0.5 acre) farm can grow up to 4 tons of food per month using the Citiponics system. The system consumes about 1% of water used in conventional farming, and 10% of water used in other hydroponic systems.

“Instead of going to the supermarket for vegetables, now we have residents that just open their window and can see the farm,” said Chan. “They get connected to their food source.” Citiponics encourages people without agricultural knowledge in Singapore to contribute to their food production process by helping with seeding, transplanting, and harvesting.

The Sustenir Agriculture system is designed to retrofit into any building in Singapore and beyond.
Indoor farming requires creating a controlled environment, with completely different methods from outdoor farming. Controlling air quality, light, and plant nutrients is a sensitive balancing act. “Being able to control the environment in its totality and understanding that every single part of an ecosystem is working and functioning correctly on a daily basis is really critical to success
Sustenir Agriculture now sells its produce in multiple grocery stores at 30% the cost of imported produce, displacing those brands that were initial competitors.

It is essential to meet our food security needs all the time. We need to fully utilise our free land such as carpark, community garden and farming technology to maximise our food production output. With this movement, it is possible for us to achieve sustainable food source. Therefore, I urge everyone to participate actively in farming!

Since the launch of the Gardening with Edibles initiative in June 2020, we distributed 860,000 free seed packets.  The programme was jointly funded by our Founding Partners DBS Bank and Tote Board through the Garden City Fund.

This Gardening with Edibles initiative brings the community together in a national gardening movement to achieve the City in Nature vision and is aligned with Singapore’s national strategy to strengthen our food resilience. The “30 by 30” goal led by the Singapore Food Agency (SFA) aims to produce 30% of Singapore’s nutritional needs locally by the year 2030. These are key goals of the Singapore Green Plan 2030, our national sustainability movement.

community gardens may be able to reduce the impact of food deserts in low-income areas and allow residents greater access to nutritious food that is necessary to live a healthy life.

Community gardens:

Help improve air and soil quality [1]

Increase biodiversity of plants and animals

Reduce “food miles” that are required to transport nutritious food

Can replace impervious structures and improve water infiltration [2]

Can reduce neighborhood waste through composting [3]

Positively impact the urban micro-climate [4]

School fields were turned into vegetable plots and schoolchildren had to spend part of the time tending their vegetable plots.
Building,¹⁶ which was turned into a tapioca field. Other common crops were sweet potatoes, various types of beans, kangkong (water convolvulus), bayam (spinach), mustard greens, and gourds such as bitter gourd and bottle gourd.
There were several issues with developing food sufficiency in Singapore. Few people knew much about farming or keeping livestock and, to make matters worse, the island’s soil for the most part was not rich in nutrients. As chemical fertilisers were not available, some resorted to enriching the land with human faeces and urine, but this practice ran the risk of contamination and the spread of intestinal parasites such as tapeworms and food-borne diseases.
