Food security is emerging as a serious and growing concern in many parts of the world.

Some of the factors that have contributed to this include the world's exploding population, land and water constraints, and floods and droughts that have impacted global food production.

Although Singapore is in good shape to tackle the rising challenges of food security, with strategies from the Agri-Food and Veterinary Authority of Singapore, such as diversifying sources of food imports, optimising local food production and stockpiling, we could all do more.

Everyone, including the young, has an important part to play in reducing food wastage.

On an individual level, we can minimise food wastage as consumers, especially when dining at buffets.

We could keep track of what food items we need and buy only those things, so that there is minimum wastage from food spoilage.

At a national level, Singapore could invest more in new technology such as vertical farming, which will aid in relieving our reliance on imported food.
