WATER
SCARCITY
WHAT IS IT?
Water scarcity happens when the demand
for water is larger than the available
supply, or when the quality of water is
poor. The amount of water that can be
physically accessed changes as supply
and demand changes. Water scarcity
increases as demand increases and/or as
water supply is affected by decreasing
quantity or quality.
Water is a limited resource in increasing
demand. As the global population
increases, many countries’ water resources
are failing to meet this rising demand. This
creates:
Shortage of access to safe and clean
drinking water
Less food production
Escalated conflict
Higher cost of living
Climate change is making water scarcity
worse. The impacts of a changing climate
are making water more unpredictable.

WATER
SCARCITY
HOW CAN WE FIX IT?
The best way for us to combat this is by improving
irrigation efficiency. About 70% of the world's
freshwater is used for agriculture and is one of the
biggest wastes on water resources. Simply
switching from flood irrigation systems to drip
irrigation systems could help the agricultural
sector save a large amount of water.
Drip irrigation involves placing tubing with emitters
on the ground alongside the plants. The emitters
slowly drip water into the soil at the root zone.
Since moisture levels are kept at an optimal range,
plant productivity and quality improve. In addition,
drip irrigation:
Prevents disease by minimising water contact
with the leaves, stems, and fruit of plants.
Allows the rows between plants to remain dry,
improving access and reducing weed growth.
Saves time, money, and water because the
system is so efficient.
Decreases labour.
Increases effectiveness on uneven ground.
Reduces leaching of water and nutrients below
the root zone.

PROJECT OVERVIEW
Our project aims to improve water efficiency a rainwater collector
and mini drip irrigation system. The rainwater system aims to use
rainwater and tap water to save water, and which can also be
used as normal water if boiled to reduce impurities. The drip
irrigation system focuses on giving a constant “drip” to the plants,
decreasing the hassle of worrying about watering the plants. This
system is incredibly easy to implement at home by using everyday
materials such as water bottles. In addition, by creating this
system, you can reduce pollution by re-using materials which
would normally be thrown away, such as plastic bottles.
