List and describe 5 agricultural or irrigation innovations:

1. Data preserved in soil

For traditional farming models, perhaps the primary determinant of supply capacity is simply the availability and suitability of land. However, any idea of future potential must be built on current data, with what data there is then mapped to tell the story of a region. This story is effectively written in the dirt, the soil.

2. Innovative agriculture moving underground

Singapore relies heavily on imports for more than 90 per cent of its fruit and vegetables. It might, therefore, surprise diners to find out that their rocket, radish and baby spinach has actually been cultivated locally. Not only that, but it has been grown in Singapore’s first licensed indoor vegetable farm, by an electronics giant better known for TVs: Panasonic.

3. Greens fed on rainbow waste

One popular innovation in agriculture is embracing a virtuous circle of reciprocity. Hydroponics, as the name suggests, is a growing method which uses mineral-enriched water. Aquaponics takes matters a step further, bringing together fish and plant farming in one recirculating system.

4. Using the sun to generate freshwater

Another of the major modern trends in agriculture is increasing water efficiency in farming and food production. Whether for traditional rural irrigation, arid regions or urban farms, this represents a key metric in the face of global population growth and climate change.

5.  Agriculture by aircraft

In the media, drones have mostly been associated with the military and spying, plus the odd pizza-delivery publicity stunt, but it could become one of the most useful innovations in agriculture, if used wisely.
