Global trends in consumption
Jan 6 & 7
How does the production of drinkable water affect the production of energy and food?
The production of drinkable water is usualy done using a dam. This divert the water in the river reducing the water flow and ristricting migratory freshwater fish. This will diminish the avalable freshwater fish supply therefore reducing the production of food. Also due to the divertion of water for drinkable water produciton, there would be less water flow making any downstream hydroelectric dams less effecient and therefore reducing the
Resource recap using Singapore as an example:
-
Why is Singapore the world’s greatest ecological debtor?
- It has a virtually no ecological biocapacity per person (a very low area that is uninhabited)
- It has a very large ecological footprint (large population density)
-
Why is Singapore a world leader in developing Water Security issues when it has abundant annual rainfall and a very small population?
- Most rainfall is sent straight into the ocean through residential wastewater systems
- Singapore is leading the way in building new water supply infrastructures like new dams and better management
-
Give an example of how Singapore’s Water consumption/strategy can be viewed through a NEXUS lens.
- Singapore's water situation means that it can't grow its own food and has to rely heavily on other nations for its food supply.
