It is physical water scarcity because the Aral Sea used to be the 4^th largest lake in 1960 but it has shrunk to half its original size because of unsustainable cotton cultivation the begun 40 years ago. But the sea can no longer be saved because its toxic salt plains paradoxically given rise to a new spirit.

 

·      Describe a solution to water scarcity here.

A solution to water scarcity in the Aral Sea is to build a dam at the foot of northern Aral. And to increase the flow from the Syr Darya, levees were strengthened, banks were straightened, and old soviet bottlenecks were removed.

 

·      Provide a positive and a negative of this solution.

Positive: The dam has prevented further decline of Northern Aral Sea and by 2011 it had helped restore the water salinity levels.

Negative: In the Aral Sea, the increasingly salty water became polluted with fertilizer and pesticides.  

·        Water Scarcity, the Aral Sea has already shrunk to half its former size, as result of unsustainable cotton cultivation that began less than 40 years ago. But though the sea itself can no longer be saved, its toxic salt plains.

 

·       Describe a solution to water scarcity here.

The dam was built at the foot of the northern Aral. To increase the flow from the Syr Darya, existing levees were strengthened, banks were straightened.

 

·       Provide a positive and a negative of this solution.

Positive: This dam has prevented further decline of the Aral Sea, and by 2011 it helped restore the water salinity level to the that of the 1960s.

Negative: As the Aral Sea has dried up, fisheries and the communities that depended on the dam. Then the water in the dam became more salty, then the dam also got polluted with fertilizer and pesticides. The blowing dust from the exposed lake bed, contaminated with agricultural chemicals, became a public health hazard.

India's dependence on an increasingly erratic monsoon for its water requirements increases this challenge. Climate change is likely to exacerbate this pressure on water resources, even as the frequency and intensity of floods and droughts in the country increases 

A solution to water scarcity in India is rainwater collection and waste water treatment because it is very cheap and easy to operate

a positive is that we get more clean water to drink and use in life but it is bad because it will cost money and time

Algeria is experiencing physical water scarcity due to lack of rainfall, even if it’s seasonal, it is still very little.

·       Describe a solution to water scarcity here.

Algeria could use desalination plants because they lack rainfall but it isn’t economic scarcity, so they can still afford a desalination plant and they can take water from around the coast.

·       Provide a positive and a negative of this solution.

A positive is that Algeria has enough money for these plants, but a negative is that desalination requires a lot of energy and electricity.

 

It’s physical since there managing the water and spending money to get water
Solution
For water scarcity you should make drains for capturing rain and make a cleaning machine to get rid of the bacteria in the rain.
Pros and cons
It will capture a lot of rain water in winter but it won’t in summer and it will cost a lot.

China is going through economic water scarcity. Climate change is one of the main factors for water scarcity, pollution is also making water quality worse, and China has 1.4 billion people that need water.

A solution to water scarcity

A solution to water scarcity that China is currently doing are sponge cities. They aim to control urban flooding, water pollution, and recycle rainwater. It retains rainwater by waterproofing paved floor so part of it evaporates and the rest gets gradually drained. As well as proofing roads and pavement, more trees can be planted, and smart buildings are constructed to adapt. Roofs are covered in grass for greater absorption of water and buildings are also panted in light colors to reflect more heat instead of absorbing the heat.

Pros and cons

 A positive is it can keep floods at bay (this is especially good for China because of its floods), and a negative is that it would take a lot of time and is extremely expensive.

Fog passes through net like object made of mesh which forms drops of freshwater which will drip into a gutter that is lying under neath the mesh net, from the gutters, pipes lead the water into a storage tank. This water can be used for irrigating crops or as drinking water.

 -Positives-
-requires no energy to operate
-it doesn’t affect many animals
-it’s cheap and easy to use

 -Negatives-
-requires specific climates
-if too much water is trapped inside the fibres, the mesh won’t drain

 Possible Solution for Water Scarcity

Britain has already instilled another way to get water for its agriculture. A Britain Company has made an irrigation system which allows saline and brackish water, which contains more saline than freshwater, to be used for growing crops. This helps to limit the risk of not being able to grow the food consumers that they require.

 Pros and Cons

The irrigation system needs minimal maintenance while the pipes must be periodically flushed to clean out the accumulated salt sand dirt. This system lets salt water be use for irrigation and fresh water be used for other uses. This increases food security for people living in dry coastal areas. Irrigation can increase erosion, pollution of surface water and groundwater from agricultural bodies and deterioration of water quality.

Why is there water scarcity in Singapore?
Climate change is a key reason on what is causing water scarcity in Singapore.

Description
A man named Adam Reutens-Tan washes under a half-full camping shower hooked on the ceiling of his bathroom. This shower that only uses 4L per shower is just one of the many ways his family conserves water as part Singapore’s push to cut daily consumptions by 8% by 2030.

 Positive
This is a good idea, considering that it does in fact cut the daily consumption of water by Singapore.

Negative
Although this idea could work, it does need work to construct together, and if built wrong then It could easily fall apart while washing.

Globle warming worsening every year making it drier with droughts which is physical water scarcity. It is also economic water scarcity because the government is not building the infrastructure or managing things well.

 

Build desalination plants because Chile is near the ocean. The government needs to manage it properly.

 

Doesn’t rely on rainfall.

Expensive.

-       It can be a pubic area so it can stop fights over the low amounts of water.


Negatives – it may not rain enough to supply enough water for everyone and can take too long to replenish.
