What is food security
When all people at all times have access to sufficient safe and nutritious food to live a healthy and active life
What physical factors affect food security
Soil- acidity, rockiness, nutrients all decide what crops grow
Water supply- all life needs water, droughts cause shortages
Temperature- crops need a specific temp to flourish
What human factors affect food security
Distribution- poor infrastructure makes it difficult to transfer food
Waste- food is not edible due to storage issues 25% in Vietnam
Climate change- rainfall patterns are changing crops can’t cope cannot be grown
8.1 on spec
What factors lead to demand outstripping food, energy and water
Population growth, rising exponentially
Economic development, more energy for industry, more food as they can afford, water for food production
Changing technology and employment, more recourses requires more tech and people to process
How are humans using mechanisms to farm/commercially fish
Fishing, bigger nets, decline in fish,
Farming, tractors, soil erosion
How are humans using deforestation and mining to provide energy
Deforestation, logging, high CO2 emissions
Mining, waste can pollute soil and contaminate water
How are humans using resevoirs and water transfer schemes to provide water
Reservoirs, floods land, damage habitats
Water transfer, lots of energy required to pump water

How does the world hunger index and average daily calorie consumption show access to food
GHI, shows how many people are suffering from hunger, on a scale of 1-100
Daily calorie intake, shows how many calories are consumed a day per person
Difference between malthusian and boserupian theories
Malthusian, population will increase faster than good supply
Boserupian, as population grows they will find ways to manage creating new technologies
Sustainability of ethical consumerism

Econ- fair price for products
Enviro- farming methods protect environment
Food waste
Soc- eat local food, helps locals

Intensive farming
Soc-fertilisers harm people
Econ- more food so cheaper
Enviro-fertilisers pollute environment
Sustainability technological developments
Genetically modified
Soc- more health benefits
Enviro- protected from disease or drought
Hydroponics
Econ- expensive
Enviro- less need for pesticides
Sustainability of bottom up approaches
Urban gardens
Soc- small community supported
