5.1 Food Security
This global issue, caused by rising temperatures and changing rainfall patterns, is one of the key threats to food security.
What is climate change?
This farming method involves growing just enough food for a family or community to survive, with little or no surplus.
What is subsistence agriculture?
Solar, wind, tidal, and wave energy are all examples of this type of energy resource.
What are renewable energy resources?
The gradual running out of oil, coal, and gas reserves contributes to this cause of energy insecurity.
What is fossil fuel depletion?
Landfill, incineration, and recycling are all examples of these.
What are methods of waste disposal/treatment?
This is the term for when all people at all times have physical, social, and economic access to sufficient, safe, and nutritious food.
What is food security?
This agricultural technique grows plants in nutrient-rich water solutions without soil, allowing food production in limited spaces.
What is hydroponics?
Oil, coal, and natural gas are all classified as this type of non-renewable energy source.
What are fossil fuels?
Natural disasters, piracy, and terrorism are all examples of this cause of energy insecurity.
What is supply disruption?
This waste disposal impact occurs when toxic substances from landfill seep through soil and contaminate underground water.
What is leaching/groundwater contamination?
Food insecurity can occur when crops are diverted away from food production to produce this type of fuel.
What are biofuels?
This strategy involves genetically altering crops to be resistant to pests or to produce a higher yield.
What are GM (genetically modified) crops?
This renewable energy source is generated from organic matter such as wood, bioethanol, and biogas.
What are biofuels / biomass?
One impact of energy insecurity is that businesses face rising operating costs, potentially leading to this economic consequence.
What are job losses / economic recession?
This process occurs when pollutants like heavy metals or pesticides become increasingly concentrated as they move up through a food chain.
What is biomagnification?
This impact of food insecurity occurs when people are forced to leave their homes and regions due to lack of food.
What is forced migration?
This UN organization provides food aid and works to combat hunger globally and is considered a key strategy in managing food insecurity.
What is the World Food Program?
Energy security is defined as the reliable availability of energy sources at an affordable price with consideration of this.
What are environmental impacts?
This strategy for managing energy security involves using less energy through better technology and building design, rather than producing more.
What is increasing energy efficiency?
The buildup of this greenhouse gas in landfill sites is both an environmental concern and a physical explosion hazard.
What is methane (CHâ‚„)?
This cause of food insecurity refers to the wearing away of topsoil and loss of fertile land through overuse, erosion, or chemical damage.
What is land degradation?
Reducing competition from weeds using herbicides, and reducing pest species using biological control are both examples of this broader food security strategy.
What is increasing agricultural productivity / efficiency?
This type of energy security refers to systems that react promptly to sudden changes in the supply-demand balance, as opposed to long-term planning.
What is short-term energy security?
This strategy for managing energy insecurity involves communities and regions producing their own power rather than depending on national grids or imports.
What is investment in local energy projects?
This waste reduction strategy involves breaking down food and organic matter naturally to produce a soil-enriching material, and is more sustainable than landfill.
What is composting?
