The solution to this is wastewater plants. 

The positives are that it treats water in less time, saves more water and is beneficial to the environment. 

However wastewater treatment plants have a pungent smell, hybrid bacteria and it takes up a lot of land space

They are using Drinkable book. this is a thing where the pages of the book can filter water. it is clean but you can run out of pages. it causes deforestation. 

Ghana has no water so they invented this drinkable book. the book shows how to manage water and the pages actually filter water.

The Deep Tunnel Sewerage System (DTSS), a 48 km long used water superhighway, conveys used water to water reclamation plants to be treated and purified into reclaimed water, or discharged into the sea.

Positive
By 2065 (estimated) NEWater and desalination will meet the majority of Singapore’s future water demand of 860 million gallons a day (mgd)

Negative
However, NEWater will not be able to produce enough potable water to be independent. It is now only able to produce 30 percent of Singapore's demand. In the future, 2060, it is predicted to meet 55 percent of Singapore’s demand.]]> 2023-06-16 04:01:17 UTC https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625168641 California, USA https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625169560 California is affected by groundwater drought. This is physical water scarcity because the water is physically not there due to the lack of rain. A solution to this water scarcity would be to recycle and replenish wastewater. This is good as you are using the water that you already have. This is also bad as the wastewater may contain chemicals that are harmful to drinking. ]]> 2023-06-16 04:02:45 UTC https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625169560 Desalination Technologies Research Institute DTRI, Al Jubail Saudi Arabiax Pav https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625170209 Physical water scarcity There is not enough water that is pure so desalination is there only option. The ways to overcome costs is solar power. One positive is it is green. One negative is it doesn't cover oil costs.]]> 2023-06-16 04:03:56 UTC https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625170209 China https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625171387 China is currently experiencing physical and economic scarcity, due to decades of floods, heavy rains and pollution that makes the water contaminated and dirty. 

Due to this, China is deciding to use 'Sponge Cities' to solve the main issue of floods. This is where they use a new urban construction model (which includes nearby trees, forests and lakes to soak up the water) for flood management and sewage problems. 

A positive aspect about this solution is that it is an extremely efficient method of managing floods and water-wise problems for civilians. 
Meanwhile, a negative point of this solution is that this project is not very eco-friendly. By this, I mean that to build a new city you need to clear out a space of land first. For sponge cities, it needs to be located basically in the middle of a large forest that can surround it. This means that you need to first clear out a huge chunk of land to build the city.

The water has been limited and unevenly dispersed. This is a physical because there isn't enough water and economical because the water is not distributed evenly. 

A sponge city is a nature based solution that uses the landscape to retain floodwaters. The main idea of a sponge city is to retain rainwater in urban areas. Paved floors are waterproofed so part of the water evaporates and the other part drains away. 
A positive side to this method is that more trees are being planted and better infrastructure is developed to adapt to the sponge city.
A negative side to this method is that it is expensive. Rebuilding a whole new eco city would be very expensive

This desalination plant are good because desalinate 60,000 cubic metres of seawater per day, enough to provide the city of Al Khafji a stable supply of drinking water.

It is bad because desalination plants are powered by oil which contributes to the release of air pollutants. They also impact marine ecosystems with the offload of harmful byproducts.

Water Scarcity - Physical
Cause of Water Scarcity - Climate Change, and a growing population
Solution - Making more infrastructure for water storage like reservoirs, managing water usage at home, and building small-scale desalination plants for agriculture.
Positive - Doesn't need a lot of maintenance, and there is a vast supply of seawater.
Negative - There is an environmental impact as the salt left over from the desalination is poured back into the ocean, and it is expensive.

Due to the climate which evaporates 83% of rainfall and a further 1% is infiltrated into the ground. Due to the climate only a little water is left for the people. Therefore, Windhoek, Namibia has physical water scarcity. 


The solution they put in place is turning wastewater into drinkable water. They use ozone treatment, ultra membrane filtration and residue chlorination to turn the wastewater effectively, into clean and drinkable water.


A positive side of this method is that turning wastewater into drinkable water is very effective for the 350000 people living in Windhoek, as they keep the cycle going. 


A downside of this is that people cannot use natural resources and  it dramatically reduces pollutant discharges.]]> 2023-06-16 04:20:18 UTC https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625179488 Kenya https://padlet.com/caitlinlangworthy1/c9u0s9quz9b6o678/wish/2625180272 type of water scarcity:
Kenya has physical water scarcity meaning, there's not enough water. Sand dams are a water solution that works in most dryland environments.

solution:
Kenya uses a sand dam, which is a water solution that works in most dryland environments.

positive:
-provides enough water for people to productively farm
-sand dams are a low-cost solution for providing water to rural communities in dry areas.

negative:

Fog is always fresh, and it can also give the citizens some washing water when it isn't fresh or clean. Although the region has many fog supplies, it does not mean that it contains a big enough amount to give to the whole population. Morocco is still expanding the places that catch fog, and some of the people there are starting to continuously use this method. Although it is highly efficient, it does not mean that there is fog everyday. The people there also rely on river water, for the wet region helps them gain the water supply for their whole population. The mountains and hills in morocco also help them catch more moist fog and bring it all the way to the town through pipes. The fences catch the water, and it then drains down to the bottom where the pipe is attached.
