Lesson8 Adaptation Flashcards
How many people in poverty work in agriculture?
2/3
What is their typical farm size?
4 acres
How many of these farms are there?
Over 500 million
What makes it hard for them?
Unpredictable weather.
What is one of the major areas of research?
Finding a drought-tolerant corn.
For how many people is corn their most important food?
1.2 billion
2.It is 30% of their calories
What else is corn (maize) used for?
Feeding animals.
How drought-resistant many maize varieties have they come up with?
Over 200
What is Scuba Rice?
A rice than can withstand long-term flooding
Why is farming a double-sided coin?
It is affected by climate change and it contributes to climate change.
Other than livestock, what else contributes to methane emission?
Rice farming.
What will rising sea levels make us do?
Move inland.
What choices are inevitable?
Do we build interim seawalls or do we start moving people?
We have new technologies to fight climate change but they are not nearly enough, yet. What is Project Vesta?
They are developing a negative emission technology called
Coastal Carbon Capture.
How does it work?
It captures carbon from the air and puts it in the oceans.
What is Chemical Weathering?
It is a natural process that has been removing CO2 for billions of years.
What isn’t good enough about this process now?
It’s too slow.
What is Vesta’s potential solution?
Uses the common mineral Olivine.
When it comes in contact with water and CO2 it transfers the CO2 to the water.
How long will the carbon stay in the ocean?
Thousands of years. As it moves through the water it moves down
What is its cost?
$50 - $75 per ton of CO2 removed, a competitive price.
What does direct-air carbon capture cost?
$100 - $200/ ton of CO2 removed.
What is their 1-year goal in carbon capture?
Capturing 1 million tons of CO2.
What is their 10-year goal?
A gigaton of CO2.
What percentage of beaches would have to have olivine on them?
.2%
What’s the biggest challenge?
You need local community agreement (social license)
