Ch.7 Food Security, Sustainability And Nutrition Flashcards
The global food price crisis of early 21 century
Food price is determined by economic, political, social and environment factor
The rising of food price will directly increase the number of hungry people in the world
Why nutrition security become more difficult to achieve?
- Inequality between people who live in the developing countries and those in developed countries become more serious
- The gap between poor and rich is widen
Major factors that affect food production
- Climate change
- Environmental changes
- changes in land use
- deforestation
- air, water and pollution
Others factors that affect food production
- Natural disasters
E.g. Volcano disruption - Human disasters
E.g. War - Inadequate supply of food for livestock or aquaculture
- Crop failure
How climate change threatening the basic of our life?
- Environment
- Water resources
- Health of human and other living organism
- Global food production
- > changes will become more pronounced
How do the climate change?
- Change in rainfall, resulting floods, droughts, or intense rain
- More frequent and intense cyclone
- More frequent and severe heat waves
The result of climate changes
- Abnormal growth of crops and crop failure
- Spreading of infectious disease of livestock
- Death of livestock and fish in aquaculture
- Reduction of global food production
Examples of environmental change
- Lots of farmlands are reduced by turning them into roads and buildings during urbanisation
- Deforestation
- > damage the natural ecology and cause deterioration of soil - Environmental pollution caused by human activities
E.g. chemicals from factories and household , water pollution
Reasons for purchasing locally grown food
- Better quality
- > less processed - Products are fresher
- > retaining more nutrients - Positive relationships have developed with producers
- Customer requests have been received for locally grown products
- > enhancing food security
Benefits of purchasing locally grown food in terms of economic development
- Consumers in particular area are purchasing more of their food from nearby sources
- > more of he money they spend remains in their local community - Support the local food industries and maintains the employment rate
Benefits of purchasing locally grown food in terms of environment
- Reducing transport distance for food can reduce fossil fuel energy use, pollution and greenhouse gas emissions
- Transportation co2 emissions were found to be greater for imported produce than domestic produce
Benefits are of food waste reduction
Environmental
Economic
Social
Benefits are of food waste reduction ( environmental benefits)
- Creating a nutrient rich soil amendment when composted
- Eliminating potential dumpster
E.g. Doors, pests and fires - Conserving landfill space and decreasing methane and other greenhouse gas emissions from landfills
- Decreasing the volume of waste managed at incinerators
Benefits are of food waste reduction (economic benefits)
Reducing and reviving excess food may save money by:
- Decreasing disposal fees
- Decreasing sewer treatment and electricity cost
- Decreasing purchasing costs
Benefits are of food waste reduction (social benefits)
- Feed people , not landfills
- Organisations can donate safe and healthy food to a food bank or food rescue organs and both reduce food sent to landfills and feed those in need
