water crisis
increased competition for land, and land degredation
climate change: warming + increase in extreme events

: overgrazing, deforestation, agriculture, urbanisation
indirect causes of global soil degradation?
population growth, economic growth
name some threats to soil degradation
soil erosion, soil organic carbon loss, nutrient imbalance, soil acidification, soil contamination, waterlogging, soil compaction, soil sealing, salinization and loss of soil biodiversity.
what is being damaged that will impact food security?
the environment: water, land and soil
does the current food system support the growing pop?
no
what are the 4 components of food securtiy?
- availability
- access
- utilisation
- stability
factors that might affect food security?
Demographics
Changes in diet
Removal of trade barriers
Increased focus on conservation
Technological innovations
Impact of climate change
what are the 4 levels of food security?
context or underlying conditions- i.e. pollitical, demographic, economic, natural resources
national/regional- i.e. access, availability, stability, supply
household- i.e. household characteristic, health and sanitation
individual- i.e. food consumption, health and nutritional status
T/F there are major envrinonmetnal costs to much land conversion
T
what are the environmental costs to land conversion
GHG emission
biodiversity
