Modification Of land & mitigation

Question 1

What are the 7 land modifications?

Answer 1

Grassland
Deforestation
Brazil
Sri Lanka
Improved aviation practices
Forested lands and tree crops
Croplands

Question 2

How can soil carbon storage be improved?

Answer 2

Irrigation- controlled amounts of water going to the plants
Not many grazing animals e.g sheep
Adding manures/fertilisers
Revegetation- adding more plants to the grasslands so it takes in more carbon

Question 3

What does mitigation mean?

Answer 3

The action of reducing something causing seriousness or pain

Question 4

What’s the mitigation potential of grasslands?

Answer 4

810million tonnes of CO2

Question 5

What happened in Sri Lanka?

Answer 5

9600 acres were replanted
They wanted to expand their mangrove forest
Protects all of its mangrove forests

Question 6

What happened in Brazil?

Answer 6

Deforestation rates were cut by 80% to stop reduction of photosynthesis

Question 7

How can decreasing deforestation help the amount of carbon in the atmosphere?

Answer 7

It can be reduced to steady the rates and therefore help with the reduction of atmospheric co2 concerntrations

Question 8

What did Malaysia do to help with deforestation?

Answer 8

An SMS is a sustainable system that replaces trees after deforestation.

Question 9

What have they done with trees in croplands?

Answer 9

They grow crops which take in co2 and burn the crop in order to create energy. It’s a carbon neutral solution.

Question 10

What does protecting the forested lands and croplands do?

Answer 10

By protecting current forests it will preserve the soil carbon stocks

Question 11

How does reforesting help co2?

Answer 11

Adding more trees and forests so it can increase the carbon density above and below the ground.

Question 12

How can improved cropland varieties help the intake and storage of co2?

Answer 12

Improved crop varieties will improve the productivity above and below the ground

Question 13

How can reducing tillage help co2 storage?

Answer 13

No ploughing protects the soil and doesn’t aggregate it to break up and release carbon

Question 14

How does mulching help croplands take in carbon?

Answer 14

Mulching is adding bark to the ground or the remainder of plants you do t use e.g roots
This stores carbon in the soil instead of the atmosphere

Question 15

What are the to improve aviation practices?

Answer 15

Total carbon sequestration potential 38Gt
Tropical afforestation 44%
Tropical agroforestry 17%

Question 16

Who and how much co2 was produced in 2013?

Answer 16

Improved aviation practices produces 705million tonnes of co2

Question 17

By 2020 how much more will the global emissions be?

Answer 17

70% higher than in 2005

Question 18

In what year did the foundation of the IPCC occur?

Answer 18

1988

Question 19

In 1988 what are the key points from the IPCC?

Answer 19

The IPCC set up a monitor and analyse climate change science and advise the UN

Question 20

What does IPCC stand for?

Answer 20

Intergovernmental panel on climate change

Question 21

What happened in 1992?

Answer 21

The UNFCCC treaty

Question 22

What are the key points in the UNFCCC treaty?

Answer 22

A general agreement to stabilise the amount of human induced greenhouse- gas levels in the atmosphere in order to prevent climate change.

Question 23

What happened in 1997?

Answer 23

The Kyoto protocol

Question 24

What is the Kyoto protocol?

Answer 24

Commits parties by setting internationally binding emissions reduction targets

Question 25

When was the Cancun, Mexico agreement?

Answer 25

2010

Question 26

What are the key points about cancun mexico agreement?

Answer 26

Set if significant decisions made to deal address long-term challenge of climate change

Question 27

When was the Doha conference ? And what was it about?

Answer 27

2012 and the conference included discussions on how to set targets for protocols e.g Kyoto

Question 28

When was the Paris conference and what happened?

Answer 28

2015 and 195 countries agreed to climate change reduction targets enforced by 2020. Aims were to reduce emissions and low global temperature by 1.5’c above pre-industrial levels.

Question 29

What happened in 2016?

Answer 29

The Marrakech conference, they demonstrated that the implementation of the Paris agreement is underway.

Question 30

According to who does 90% of anthropogenic carbon release comes from the combustion of hydrocarbons?

Answer 30

The IPCC

Question 31

By what percentage do scientists estimate the carbon capture can cut emissions by?

Answer 31

90%

Question 32

Name and locate the worlds first commercial carbon capture coal-fire power plant

Answer 32

Saskatchewan

Question 33

How can carbon capture be used to reduce the amount of co2 entering the atmosphere through combustion?

Answer 33

Using technology to capture co2 from industry and put it underground

Question 34

Why do environmentalists have concerns about carbon capture?

Answer 34

They’re making it viable because they’re making oil and extracting it. One day oil will run out and they won’t be able to afford it

Question 35

How can countries use photosynthesis to reduce their carbon emissions?

Answer 35

Planting more trees to act as a carbon sink

Question 36

What does FSC stand for?

Answer 36

Forestry stewardship council
