play00:07

About 10,000 years ago, humans began to farm.

play00:12

This agricultural revolution was a turning point in our history

play00:16

that enabled people to settle, build and create.

play00:21

In short, agriculture enabled the existence of civilization.

play00:26

Today, approximately 40 percent of our planet is farmland.

play00:31

Spread all over the world,

play00:33

these agricultural lands are the pieces to a global puzzle

play00:37

we are all facing:

play00:39

in the future, how can we feed every member of a growing population

play00:44

a healthy diet?

play00:46

Meeting this goal will require

play00:48

nothing short of a second agricultural revolution.

play00:52

The first agricultural revolution

play00:54

was characterized by expansion and exploitation,

play00:58

feeding people at the expense of forests, wildlife and water

play01:03

and destabilizing the climate in the process.

play01:07

That's not an option the next time around.

play01:10

Agriculture depends on a stable climate

play01:14

with predictable seasons and weather patterns.

play01:17

This means we can't keep expanding our agricultural lands,

play01:21

because doing so will undermine the environmental conditions

play01:24

that make agriculture possible in the first place.

play01:28

Instead, the next agricultural revolution

play01:31

will have to increase the output of our existing farmland for the long term

play01:35

while protecting biodiversity, conserving water

play01:39

and reducing pollution and greenhouse gas emissions.

play01:44

So what will the future farms look like?

play01:47

This drone is part of a fleet that monitors the crops below.

play01:52

The farm may look haphazard

play01:54

but is a delicately engineered use of the land

play01:57

that intertwines crops and livestock with wild habitats.

play02:01

Conventional farming methods cleared large swathes of land

play02:05

and planted them with a single crop,

play02:08

eradicating wildlife

play02:09

and emitting huge amounts of greenhouse gases in the process.

play02:14

This approach aims to correct that damage.

play02:18

Meanwhile, moving among the crops,

play02:20

teams of field robots apply fertilizer in targeted doses.

play02:25

Inside the soil,

play02:26

hundreds of sensors gather data on nutrients and water levels.

play02:31

This information reduces unnecessary water use

play02:34

and tells farmers where they should apply more and less fertilizer

play02:38

instead of causing pollution by showering it across the whole farm.

play02:43

But the farms of the future won't be all sensors and robots.

play02:48

These technologies are designed to help us produce food

play02:51

in a way that works with the environment

play02:54

rather than against it,

play02:55

taking into account the nuances of local ecosystems.

play03:02

Lower-cost agricultural practices can also serve those same goals

play03:07

and are much more accessible to many farmers.

play03:10

In fact, many such practices are already in use today

play03:14

and stand to have an increasingly large impact

play03:17

as more farmers adopt them.

play03:20

In Costa Rica,

play03:21

farmers have intertwined farmland with tropical habitat so successfully

play03:26

that they have significantly contributed to doubling the country's forest cover.

play03:30

This provides food and habitat for wildlife

play03:33

as well as natural pollination and pest control

play03:36

from the birds and insects these farms attract,

play03:39

producing food while restoring the planet.

play03:43

In the United States,

play03:44

ranchers are raising cattle on grasslands composed of native species,

play03:48

generating a valuable protein source

play03:51

using production methods that store carbon and protect biodiversity.

play03:56

In Bangladesh, Cambodia and Nepal,

play03:59

new approaches to rice production

play04:01

may dramatically decrease greenhouse gas emissions in the future.

play04:05

Rice is a staple food for three billion people

play04:09

and the main source of livelihood for millions of households.

play04:12

More than 90 percent of rice is grown in flooded paddies,

play04:17

which use a lot of water

play04:19

and release 11 percent of annual methane emissions,

play04:23

which accounts for one to two percent

play04:25

of total annual greenhouse gas emissions globally.

play04:29

By experimenting with new strains of rice,

play04:32

irrigating less

play04:34

and adopting less labor-intensive ways of planting seeds,

play04:38

farmers in these countries

play04:39

have already increased their incomes and crop yields

play04:43

while cutting down on greenhouse gas emissions.

play04:47

In Zambia,

play04:48

numerous organizations are investing in locally specific methods

play04:52

to improve crop production, reduce forest loss

play04:56

and improve livelihoods for local farmers.

play04:59

These efforts are projected to increase crop yield

play05:02

by almost a quarter over the next few decades.

play05:06

If combined with methods to combat deforestation in the region,

play05:10

they could move the country

play05:11

toward a resilient, climate-focused agricultural sector.

play05:16

And in India,

play05:18

where up to 40 percent of post-harvest food is lost or wasted

play05:22

due to poor infrastructure,

play05:23

farmers have already started to implement solar-powered cold storage capsules

play05:29

that help thousands of rural farmers preserve their produce

play05:32

and become a viable part of the supply chain.

play05:37

It will take all of these methods,

play05:39

from the most high-tech to the lowest-cost,

play05:42

to revolutionize farming.

play05:44

High-tech interventions stand to amplify

play05:47

climate- and conservation-oriented approaches to farming,

play05:51

and large producers will need to invest in implementing these technologies.

play05:55

Meanwhile, we'll have to expand access to the lower-cost methods

play05:59

for smaller-scale farmers.

play06:01

This vision of future farming will also require a global shift

play06:06

toward more plant-based diets

play06:09

and huge reductions in food loss and waste,

play06:12

both of which will reduce pressure on the land

play06:15

and allow farmers to do more with what they have available.

play06:20

If we optimize food production, both on land and sea,

play06:24

we can feed humanity

play06:25

within the environmental limits of the earth,

play06:29

but there's a very small margin of error,

play06:32

and it will take unprecedented global cooperation

play06:36

and coordination of the agricultural lands we have today.
