Desertification
land degradation occurs in arid, semi-arid and dry sub-humid areas
What is a myth about desertification? (Any land can be and is affected by land degradation/desertification - only is more easily visible near desert and dry areas.)
The primary cause of global warming
What are people?
Long lasting droughts caused by climate change are forcing people to face this risk.
What is famine?
Availability, Access, Utilization, Stability
What are the four dimensions of Food Security
Causes of desertification
What is misuse of land, overuse of livestock, over tilling and extracting more use from the soil than can handle?
Global temperature rise scientists say will mitigate the worst effects of climate in °C
What is 1.5 °C?
Aside from oil and gas mines, this industry which feeds the world is a significant source of methane emissions.
What is agriculture?
Lower quality soil means less healthy crops grown so there is less to go around.
What is the effect of desertification on Availability?
Desertification Solutions
What is mindful use of livestock (allowing them to move naturally), changing our patterns of agriculture, studying soil, lowering global temperatures to combat rapid evaporation of soil?
The percentage of people breathing unhealthy levels of air pollution.
What is 99%?
Desertification is a driving cause of three problems facing most developing countries.
What are poverty, famine and displacement?
Inconsistent and unreliable yields can cause shortages and price spikes and can cause those with less funds to go hungry.
What is the effect of desertification on Access?
2/3 of the world
How much of the world is affected by Desertification?
Long-term shifts in temperatures and weather patterns.
What is the UN definition of climate change?
Planting trees on sand dunes where they didn't originally grow in can worsen this problem instead of stopping the expansion of deserts.
What is erosion?
Uncared for soil can become lacking in nutrients and less possible to be useful in the future for crops leading to more and more desertification.
What is the effect of desertification on Utilization?
Common consequences of desertification
What is displacement of people, less food, and carbon released from soil (further contributing to climate change)?
Shifting to net zero by 2050 would do this to the economy
What is a 7 percent increase in global GDP?
The percentage of the world’s population affected by desertification
Over 40% of the world faces this.
Unreliable land leads to unreliable yields which can cause upset and more shortages.
What is the effect of desertification on Stability?
