factors
what is land degradation?
Land degradation is when a piece of land has been overused or over farmed, whether that means growing crops or grazing animals.
how is it a threat to food accessibility
It’s a threat to food accessibility because if farmers or the government are destroying fertile land that has the potential to provide food, then food isn’t going to be produced
Poverty will increase, demands will increase, less money is brought into the economy.
What happens if land degradation doesn't stop?
There will be consequences economically, environmentally and societally.
What is Crop Rotation
when you use the same land for different crops throughout different seasons
what is soil erosion
soil erosion is when soil falls away or is broken apart either with machinery or natural occurrences such as wind or rain
how is it a threat to food accessibility
Land degradation can lead to crop failure and heavily affect the quantity and quality of food being produced
Economic consequences?
Food will be expensive. Jobs and families can lost.
give an example of a sustainable way to farm
crop roation, fertility from animals, strip grazing
what is soil salinity
soil salinity, soil contains salt. When trees and plants are removed from the land, the salt in the soil rises, making the land too salty to grow crops or act as pastures
The FAO estimates how many are people facing hunger on both extreme and unextreme levels in the world,
2.3 billion
How is society impacted?
Families will fall apart and conflict between individuals will arise.
Environment consequences?
Less farm to land, bringing less food, less crops and climate change.
what is soil security
its when the soil is maintained. improving the world's soil resource to produce food, fibre and freshwater,
what is Soil acidification
Soil acidification is when the PH level of the lands soil is lowered over time. This can be caused by adding toxic and acidic fertilizers to the soi
if land degradation and desertification rates continue to increase and by 2050 food insecurity will affect how many people
3 billion
How does not getting food impact your health?
Experiences could be, stress, anxiety and fear of starvation.
Society consequences?
Higher death rates, conflicts between individuals to survive.
what is crop rotation
Crop rotation is the practice of growing a series of different types of crops in the same area
what is desertification
desertification is a combination of overgrazing, erosion, and poor land management practices, which can lead to a degradation of the soil's ability to retain water and support plant growth.
land degradation will cause how many people relocate to different regions
at least 700 million people to relocate to different regions
If land degradation continues how will it impact Australia?
Economically, Environmentally, Socially, Cultural.
What can YOU do to stop it.
Limit food waste/Plant based food/Recycling food/composting and anything that can fit here.
list three solutions
crop rotation, sustainable farming and less pollution
