随着新型机械不断地被发明，人们对劳动密集型耕作方式的依赖在逐日减少。然而，以下这一景象会成为现实吗？农民不再需要下地干活，机器人会承包所有的工作。这是英国及世界各地的科学家们正在尝试的一个想法。

Imagine a future where all farming is done by machine, and humans never set foot in the fields.

No, it’s not science fiction. In Shropshire in the UK, engineers in the Hands Free Hectare project are developing automated tractors and fleets of drones to grow and harvest crops.

And their experiment is not alone: agricultural robotics is a booming sector. Investment bank Goldman Sachs estimates the market will be worth $240bn over the next five years.

One reason why the sector is on the up is that global demand for food is rapidly increasing. The World Bank estimates we will need to produce 50% more food by 2050 if the planet’s population continues to grow at its current speed. Add to this to the forecast that yields will decrease by over a quarter due to climate change, and the situation looks serious.

Could futuristic farming provide the answer?

One company in Japan believes so. The firm Spread has dispensed with farming on land altogether, and instead grows vegetables on stacks of trays indoors in an automated factory.

"In countries like Japan, where land is actually a very scarce resource, it makes more sense to stack your production, just like a skyscraper," says JJ Price, Spread's global marketing manager.

Mr Price told the BBC that this method of vertical farming not only reduces costs by 50%, but it is also greener. LED lights cut energy bills by a third, and 98% of water can be recycled. By growing crops close to where people consume them, transport costs and emissions are also minimised, he says. They hope to be producing 30,000 lettuces per day next year.

And where will we buy this futuristic food? Perhaps in shops with no staff? Amazon has recently launched its first Amazon Go store in the US, which has no checkouts. Customers simply pick their items from the shelves, and technology does the rest.

All this begs the question: if everything is automated, what jobs will people do? The mechanisation of farming means fewer and fewer people work the land. From 1950 to 2010, agricultural labourers have decreased from 81% to 48.2% of the workforce in developing countries, and from 35% to 4.2% in developed countries, according to the International Labour Organization. It’s a trend that looks set to continue.

1. Why does Spread think vertical farming makes particular sense in Japan?
Spread believes vertical farming makes particular sense because there is so little land available for farming in Japan.

2. What is likely to happen to the agricultural workforce in the future?
There are likely to be fewer people working in farming in the future. The workforce will get smaller.

3. Which two factors do the World Bank think will put pressure on food production?
The World Bank thinks climate change and population growth will put pressure on farming to become more productive.

4.Which word means: ‘more environmentally friendly’?
Greener.

5. True or false: Goldman Sachs predicts the market for automated tractors will be worth $240 billion in five years.
False. Goldman Sachs estimates the market for agricultural robotics will be worth $240 billion over five years.
