00:00:00,440 --> 00:00:03,870
 Did you know NASA keeps track of food production from orbit?

2
00:00:03,870 --> 00:00:07,420
Pioneering scientists in the 1980’s realized that satellites 

3
00:00:07,420 --> 00:00:10,980
could “see” plants growing from space.

4
00:00:10,980 --> 00:00:14,150
This monumental discovery occurred when NASA scientists

5
00:00:14,150 --> 00:00:17,930
figured out how to use satellites to measure chlorophyll in plants 

6
00:00:17,930 --> 00:00:21,650
which is reflected as green light into space. 

7
00:00:21,650 --> 00:00:26,790
With a flood of new data pouring in, NASA, USDA and the University of Maryland

8
00:00:26,790 --> 00:00:30,040
created an online tool that could track crop health 

9
00:00:30,040 --> 00:00:32,500
anywhere in the world in near-real-time. 

10
00:00:32,500 --> 00:00:37,980
The team called the inaugural platform, GLAM – Global Agricultural Monitoring.

11
00:00:37,980 --> 00:00:42,510
The system has withstood the test of time and is still in use today.

12
00:00:42,510 --> 00:00:46,860
Inspired by technological advancements and increased computing power in recent years, 

13
00:00:46,860 --> 00:00:50,720
additional global agricultural monitoring systems have been developed,

14
00:00:50,720 --> 00:00:53,700
including NASA Harvest’s GLAM 2.

15
00:00:53,700 --> 00:00:58,430
Here at home, when a massive derecho hit the Midwest in August of 2020, 

16
00:00:58,430 --> 00:01:02,720
satellite data helped analysts to rapidly assess the damage.

17
00:01:02,720 --> 00:01:07,170
This natural disaster caused upwards of four billion dollars in damage 

18
00:01:07,170 --> 00:01:10,920
one of the costliest windstorms of the past decade. 

19
00:01:10,920 --> 00:01:14,480
Using Earth observation data for these types of damage estimates 

20
00:01:14,480 --> 00:01:20,210
helps American and international markets prepare for potential commodity crop shortages. 

21
00:01:20,210 --> 00:01:23,660
In the face of more extreme weather due to our changing climate, 

22
00:01:23,660 --> 00:01:27,880
food security is one of the most important challenges of this century. 

23
00:01:27,880 --> 00:01:31,360
NASA technology is helping keep our leaders informed

24
00:01:31,360 --> 00:01:35,630
our markets stable, and our populations fed.

25
00:01:35,630 --> 00:01:45,344
