Solutions to water scarcity
How to prevent water shortages?
Water stress is a serious issue in many parts of the world. Discover its causes and effects, but most importantly the solutions to the water crisis.
Water is one of the most precious resources on the planet. More than 1 billion people do not have access to a source of clean drinking water, and around 3 billion experience water scarcity at least one month per year.
What is the definition of water scarcity? What are its causes and effects? And most importantly, how to overcome the water scarcity problem?

03. Definition
What is water scarcity?
Water scarcity, both natural and of human origin, is the lack of sufficient available water resources to meet the demands within a region. Water is unequally distributed over time and space. Much of it is wasted, polluted and unsustainably managed.
There is no global water scarcity as such, but a number of places and regions are chronically short of water because its use at the global level has increased more than twice as fast as the population over the last century.
Pressure on water resources is increasing in several parts of the world, especially in China, India, Pakistan, in the Middle East and many countries and regions of Africa.

05. Effects
Water scarcity Effects
Water shortages have a great impact on human health, socio-economic development, and the environment:
1. Hunger, poverty and education
Apart from dehydration due to the obvious lack of drinking water, hunger is one the most serious effect of water scarcity. Why? Water shortages have a direct impact on crops and livestock, which can lead to food shortages and eventually starvation. As well, because of water shortages some people cannot shower, wash their clothes or clean their homes properly.
In the poorest countries, some children can’t go to school, because they are either too sick or they have to walk for a long time to reach a water source. Even when they can attend, many children cannot learn because of their fatigue, heavy responsibilities and worries for their families.
2. Sanitation issues and diseases
Water scarcity generates sanitation problems by forcing people to drink unsafe water. In fact, when water is scarce people tend to store it at home, which increases the risk of domestic water contamination and creates breeding grounds for mosquitoes, which transmit dengue and malaria.
Lack of water cause other diseases such as trachoma (an eye infection that can cause blindness), plague and typhus.
3. Conflicts
Having access to water has become a powerful global economic issue that could become one of the main causes of international tension. Local conflicts - sometimes resulting in warfare - are triggered over scarce water resources. With the burgeoning global population and growing needs, these tensions could multiply in the future.
4. Biodiversity loss
Water scarcity has different negative impacts on rivers, lakes, and other freshwater resources. It harms the environment in several ways including increased salinity, nutrient pollution, and the loss of floodplains and wetlands. Ecosystems and biodiversity (e.g. freshwater fish) are threatened by the scarcity of water resources.
06. Prevention
Water scarcity prevention
There are ways to save water and prevent water scarcity:
1. Sustainable water management
Improving water infrastructure must be a priority, as water conservation and efficiency are key components of sustainable water management. Solar desalination and smart irrigation systems are great examples of clean technology for water efficiency and control. That obviously applies even more to the agriculture and farming sector - the largest consumer of water.
2. Reclaimed water
Rainwater harvesting and recycled wastewater also allow to reduce scarcity and ease pressures on groundwater and other natural water bodies. Groundwater recharge, that allows water moving from surface water to groundwater, is a well-known process to prevent water scarcity.
3. Pollution control & better sewage treatment
Without proper sanitation, the water becomes full of diseases and unsafe to drink. That is why addressing pollution, measuring and monitoring water quality is essential. Besides, improving the sewage systems in specific areas is another way to prevent water scarcity from becoming any worse.
4. Awareness & Education
Education is critical to solve the water crisis. In fact, in order to cope with future water scarcity, it is necessary to radically reform all forms of consumption, from individual use to the supply chains of large companies.
