Food security- B6.2.1

what is food security

when everyone has access to safe nutritious food

what factors affect food security

1. increased pop

2. changing diets- as people become wealthier, they tend to eat more meat

3. Climate change- areas that were once fertile may no longer receive the right amount of rainfall

4. new pests

how can we increase food production

1. maximise photosynthesis- industrial greenhouses

2. using fertilisers- help land to remain fertile

3. remove pests

4. planting variety of crops to increase yield

what is intensive farming—— HIGH YIELD

use chemical fertilisers

minimise use of manual labour to replace with machinery

maximise growth rates of animals

what is organic farming——— LOW YIELD

use natural fertilisers

more labour intense

avoid use of pesticides/chemicals
