For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
a damming a river increases the supply. Supply side solution. There's more water there.
b desalinating seawater definitely increasing the supply. You create drinking water from what was not there before.
c invading nation for rivers increasing the supply (not by much. The people who are there still need their water).
d Raising water prices reducing the demand
e Tax breaks reducing (and maintaining) the demand
f drip irrigation reducing the demand.
As stated in the above question, supply side solutions increase the supply of fresh water. This means that the options that will increase the level of fresh water that will be offered to the consumer will be on the supply side, that is, those options that will provide plenty of choice for the consumer should be on the supply side, so we can say that the solutions are: desalinating seawater, damming a river to create a reservoir, a nation invading a neighboring country to access their rivers
The above question also states that demand-side solutions will reduce demand for fresh water. This means that these solutions should discourage consumers from paying for or limiting their use of fresh water. These solutions are: raising water prices for consumers and businesses, providing tax breaks for companies that use less water, requiring low-flow shower heads in new homes, replacing inefficient irrigation with more-efficient drip irrigation to grow crops
