Geography

• What causes land and soil degradation?


  unstainable farming, deforestation, overgrazing.
• Mixed Faming


  Livestock and Crops
• Commercial Farming 


  Based on business
• Intensive Faming


  Large inputs of money to make farm land bigger
• Sedentary Faming


  Same crops are planted on the same land every year.
• Nomadic Farming


  People who move from place to place in search for food and land for the livestock.
• Degradation


  When the quality of something is deteriorated.
• Hunger


  the distress associated with lack of food.
• Food Security


  everyone has enough good quality food to eat to stay healthy and active
• Malnutrition


  Not having enough nutritious food to stay healthy
• Undernourishment 


  not getting enough food to meet basic energy need
• More developed countries

  undernourishment may still exist but is often less prevalent
• Less developed countries

  undernourishment is often more prevalent due
• Global food Crisis


  not enough food for many people around the world, leading to hunger and malnutrition on a large scale.
• Sustainable


  actions that can be maintained over the long term without causing harm to the environment, society, or economy.
• Yeild


  the amount of something produced or provided.
• Deforestation


  clearing forests to make space for other uses like farming, cities, or roads.
• Urbanisation

  more people move from the countryside to live in cities,
• Agriculture


  growing crops and raising animals for food and other products.
• Taiga


  coniferous trees
• tropical forest


  green forests found in warm, rainy areas near the equator.
• Temperate Forests


  mild climates, with trees that shed their leaves in the fall and grow them back in the spring.
• grasslands


  low plants, with few trees.
• Shifting Cultrivation


  clear small areas of forest, burn the vegetation, and grow crops for a few years before moving to a new area.
• mixed crop cultivation


  farmers grow different crops together in the same field.
• Extensive Pastoral Farming


  cattle roam freely over large area
• Biofules

  plants are used to make fuel for cars, there's less food for people so prices can go up, making it hard to get enough food.
• How has competition for land use contributed to the global food crises

  more land is used for things like building houses or growing crops for fuel, there's less land for growing food
• Water Scarcity


  there's not enough water to grow crops
• Armed Conflict


  damage farms, disrupt food production, and make it hard for people to get food.
• How has threats to non native plants contributed to the global food crises


  they can compete with food crops for resources like water and nutrients, making it harder for crops to grow well
• Plants and animals

  damage crops, Invasive species can compete with crops, Overfishing and habitat loss
