Resource management water

• What is the term for the distance food travels from field to fork?

  Food miles
• Organic produce is food produced without the use of chemicals
• Water stress occurs when the demand for water exceeds the supply.
• What is the purpose of a water transfer scheme?

  Matching supply with demand
• The energy mix refers to a range of energy sources that can be renewable or non-renewable
• The UK currently has complete energy security.

  False
• Order the following imported foods by food miles, from furthest to nearest.

  1️⃣ Lamb from New Zealand

  2️⃣ Beef from Argentina

  3️⃣ Prawns from Thailand

  4️⃣ Mangoes from Brazil

  5️⃣ Beans from Kenya

  6️⃣ Bananas from Dominica
• Manufacturing is the odd one out in a list that includes washing clothes, showering, and flushing toilets
• What is the main reason for increasing water demand in the UK?

  Growing population
• Fertilizer runoff is a source of water pollution.
• Waterborne diseases are caused by microorganisms transmitted in contaminated water
• What is desalinization?

  Removing salt from seawater
• Gray water can be used immediately as fertilizer for plants.
• Which sector uses the most water globally?

  Agriculture
• The process of applying water to land to supply crops is called irrigation
• Water stress occurs when water supply exceeds demand.

  False
• What is the primary source of water for aquifers?

  Rainfall
• Water insecurity refers to a situation where water availability is not sufficient to ensure health, livelihood, and earnings
• Over-abstraction occurs when water is used more quickly than it is replaced.
• What is desalinization?

  Removing salt from seawater
• Economic development contributes to increased water consumption due to the growth of commercial agriculture and thirsty industries
• What are the main sources of water?

  Rivers, lakes, aquifers
• Aquifers are natural underground stores of water in porous rocks.
• How are reservoirs created?

  By building a dam
• Tropical or temperate humid climates have the most water availability
• Mountainous areas receive large amounts of precipitation.
• Why is geology important for water availability?

  Creates aquifers
• Pollution makes water supplies unfit for human use, increasing the risk of diseases such as cholera
• Over-abstraction occurs when water is pumped faster than it is replenished by rainfall.
• What is one impact of water insecurity on food production?

  Lower crop yields
• Water insecurity affects industrial output by increasing the cost of water
• Categorize the impacts of water insecurity:

  Social/Political ↔️ Waterborne diseases

  Economic ↔️ Rising costs

  Environmental ↔️ Over-abstraction
• Steps in the desalinization process:

  1️⃣ Sea water intake

  2️⃣ Infiltration

  3️⃣ Reverse osmosis

  4️⃣ Re-mineralization

  5️⃣ Storage

  6️⃣ Water outflow
• What is added to desalinated water to meet drinking standards?

  Minerals
• Concentrated seawater from desalinization is returned to the ocean through diffusers.
• What is one benefit of large-scale water transfer schemes?

  Increases GDP
• Large-scale water transfer schemes often require huge loans, leading countries into debt
• What is displaced when building dams for water transfer schemes?

  People
• Small-scale sustainable water schemes use appropriate technology that local people can maintain.
• Small-scale water schemes emphasize community management
