Biomes
A large ecological region defined by characteristic climate, soils, vegetation, and animals.
Biome
The process of diverting water from a freshwater system to farmland
Irrigation
Gasses that trap heat in the atmosphere including; Carbon Dioxide, methane, and Nitrous Oxide.
Greenhouse gases
household-level economic and social condition of limited or uncertain access to adequate food.
Food Insecurity
Planting a sequence of different crops in a field over a period of time, rather than planting the same crop repeatedly.
Crop Rotation
What are 2 factors that affect Biome characteristics (animals, vegetation etc.)?
Climate, Latitude, Rainfall (precipitation)
The largest river system in Australia
Murray Darling River Basin
What are these effects of? More droughts, more rainfall, and more severe weather events
Effects of global warming
Climate change, Soil degradation, Water Scarcity, and Type of biome are what factors challenging food security?
Environmental
Better storage facilities, Consumer awareness, and Use-by date education are solutions to?
Food Waste
Give two human activities that significantly alter grassland biomes
Land-Clearing and over-irrigation
urban farming, organic farming, agroforestry, precision farming, crop-rotation are examples of?
Climate- temperature, rainfall, humidity, and seasonal patterns.
Soil quality- fertility, nutrient content, pH, and structure
Topography- slope, elevation, and landform
Natural factors that affect food production.
What disrupts farming, transport, and trade of food. It also displaces people who become refugees and often face food shortages
Conflict and war
Using GPS, sensors, and data to apply water and fertiliser only where needed
Precision agriculture
Biome that dominates Northern Territory
Tropical Grasslands (Savanna)
The byproduct of over-irrigation which can lead to massive fish kills
Algae bloom and/or Salinisation
The human-induced process in which the quality and fertility of land is reduced by over-cultivation, deforestation, and unsustainable farming practice.
Desertification
what governmental policies can affect food security
tariffs and trade restrictions
Protecting arable land, Reforestation, soil conservation and Global cooperation are solutions to?
Climate Change
Biome best for producing food?
Grasslands
combining trees with crops to improve land use and reduce erosion, for example, interplanting.
Agroforestry
A loss of natural vegetation, habitats and biodiversity. desertification and cliamate change are impacts of what?
Deforestation
What can increase demand for food faster than it can be supplied
Population growth
Rainwater Harvesting, Drip irrigation, and Water restrictions are solutions to?
Water Scarcity
