Biomes and Food Security Flashcards
What is a biome
A large area of the earths surface characterized by its climate, flora and fauna and ecosystems that have adapted to that environment
Identify the 8 main biomes
Tropical Rainforest, Temperate Forest, Grasslands, desert, Boreal forest,Tundra, Marine and Freshwater
What are the factors that determine the distribution of different biomes
Latitude, Mountains, Altitude and ocean currents
define food security
a state where all people at all times have access to enough safe, nutritious food to sustain a healthy life
what are the four ‘pillars’ of food security
Food availability, food accessibility, food stability and knowledge and resources to use food appropriately
what is food availibilty
Ensuring there is a sufficient supply of food through production and distribution.
what is food accessibility
Ensuring people can physically and financially access food.
what is food stability
Ensuring reliable access to food over time, even amid disruptions.
identify three threats to food security
climate change, land degradation and water scarcity
explain one threat to food security in detail
Climate change threatens food security by increasing the frequency and strength of extreme weather events, altering annual rainfall and creating crop failures.
identify a solution to food insecurity and explain it (1)
Genetically modified (GM) foods are crops altered for desirable traits, such as pest resistance or higher yields, and can enhance food security by increasing agricultural productivity and resilience.
identify a solution to food insecurity and explain it (2)
Investment in farming technology, including precision agriculture and vertical farming, enhances crop yields and optimizes resource use. By increasing food production and resilience to climate change, they can contribute to global food security
Explain how a region is affected by climate change
In sub-Saharan Africa, shifting rainfall and rising temperatures threaten rain-fed agriculture, contributing to crop failures and disrupting food stability, putting millions at risk of food insecurity.
