Biome Productivity
What is a biome?
a region defined by a specific climate, dominant vegetation, and distinct animal life
What is extensive farming?
Farming which requires a large area of land
What is food utilisation?
The way our food is stored and prepared and individual food practices, ensuring there is a positive nutritional impact on people
What is sustainable farming?
an approach to producing food and fiber that meets current needs without compromising the ability of future generations to meet their own needs
What is a GMO?
Genetically Modified Organism
What is the biome which is the most productive?
Wetlands
What is intensive farming?
Farming which only requires smaller amounts of land
What are the three areas of Food security?
Accessibility, Availability and Utilisation
Is sustainable farming accessible to all farms and crops? why?
No, sustainable farming is not equally accessible to all farms and crops due to barriers like:
- high initial costs
-the need for specialised knowledge and technology
- limited infrastructure
- market access issues
What is global Warming?
a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide (human induced)
What is a primary producer?
Primary producers are things that make their own energy using sunlight, water and carbon dioxide
What is irrigated farming?
an agricultural practice that artificially applies water to crops by diverging from water supplies such as rivers.
Identify 3 threats to food security
- Water scarcity
- Competition for Land
- War and Conflict
- Land usage for fuel instead of food
- Climate Change
Identify 3 benefits sustainable farming?
- healthier crops
- less environmental impact
- improved animal welfare
- stops crop disease
- prevents soil erosion
What challenges do Australian farmers have to deal with in terms of their soil?
- It is ancient
- has less nutrients
- lots of salt because it used to be underwater
- lots of clay in soil
What is net primary productivity?
Net productivity is energy made by the plant that the plant uses minus the amount they store
What is land degradation?
the decline in the health of land, reducing its ability to support life and ecosystems.
Caused by:
- human activities like agriculture and unsustainable land management
- extreme weather like drought
What is food security? (Use exact and specific wording)
the state of having reliable access to enough affordable and nutritious foods that allow people to live a healthy life.
Why do some people think rice growing in Australia is unsustainable?
- high water demand, especially in an environment facing drought and climate change, - leads to reduced water availability
- competition with other crops for water usage
Define all 3 aspects of food security
Availability: The Physical presence and reliable supply for sufficient food from domestic or global production to meet the needs of the population
Accessibility: The ability of individuals and households to obtain sufficient nutritious foods to lead a healthy life
Utilisation: The way our food is stored and prepared and individual food practices, ensuring there is a positive nutritional impact on people
