In the theme of high-tech farming as part of the Alternative Food Network system, I have learnt that:
- AFN is not necessarily less pollutive than commercial farming
- High-tech farming in indoor and urban conditions are expensive, although the energy consumed is at an efficient rate
- If Singapore wants to enhance its food security through more vigorous urban food production, Skygreen’s vertical green model is more apt than the LED lighted agriculture.
- LED lights should be powered by electricity produced by renewable and green energy so that it does not emit carbon like the animal farms and cause greenhouse effects.
