What Is Water Scarcity?

Water scarcity is a lack of fresh water to meet the needs of a population.[1] However, answering the question “What is water scarcity?” is much more complicated than that basic definition, and many elements need to be discussed.


First, it is important to note that the UN General Assembly has made water availability a high priority for many years. Back in 2010, the UN looked at water scarcity facts and said, “Everyone has the right to sufficient, continuous, safe, acceptable, physically accessible, and affordable water for personal and domestic use.”[2] Even so, 2 billion people use a drinking water source that is contaminated with feces, which often results in disease.[3]

What is water scarcity? The Causes.

There are two types of water scarcity—physical water scarcity and economic. These types of scarcity can have many causes. The demand may be greater than the supply, the infrastructure may be lacking or institutions may not be balancing the needs of those in the community. The three most impactful causes are as follows:
  • Climate / Pollution – Even though water covers 70 percent of the earth, freshwater is in short supply, representing only 3 percent of the earth’s water. Two-thirds of that freshwater is inaccessible.[4] Many of our water systems are stressed and other sources of water are becoming too polluted to use safely. The impacts of climate change and pollution are intensifying the challenges of water scarcity, resulting in decreasing availability of freshwater and increased risks of water-borne illnesses and contamination.[5]
  • Agriculture – A large part of water usage is for agricultural irrigation. According to World Wildlife Fund, many countries that produce a lot of food, like the United States, China, Australia and Spain, are close to reaching their water resource limits.[6] Agriculture can also be the cause of water pollution due to pesticides and other chemicals used in farming.[7]
  • Population Growth – Rapid population growth and industrialization has led to the transformation of natural water ecosystems and loss of biodiversity, resulting in unsustainable use of freshwater and water stress for 41% of the world’s population. Additionally, the growing population’s demands for basic necessities puts pressure on freshwater resources.[8]
Water scarcity impacts individuals as well, especially among the world’s poor. There is often limited access to safe water for drinking, cooking and hygiene. Women and girls are most impacted because they are commonly responsible for collecting water, sometimes walking for hours just to reach the nearest water source. This impacts employment and educational opportunities for women and girls. It is also very physically demanding.

Ragnar and his family of six fought hard to get water at the closest water source that was over half a mile from their home. People would jostle for position in line to gather the unclean water. It carried diseases like cholera, dysentery, typhoid or diarrhea. They would fight for water that would often make them sick.[9]

Ragnar’s kids struggled in school because they were frequently sick. Ragnar wanted better for his children. He wanted them to feel well and excel in school and in life. He took his jaundiced son to a local doctor, who recommended he drink filtered water. But Ragnar couldn’t afford such a luxury.

Dabid, a GFA missionary, met Ragnar along the path in their village one day and they began to chat. Ragnar’s troubles poured out as he shared of his son’s sickness and their water situation. Immediately, Dabid went to the family’s home to pray for them and also assured them he could help in a very tangible way. Dabid and his church began to pray for a Jesus Well to be constructed in Ragnar’s village, and soon their prayers were answered!

Now Ragnar and his children have access to pure, clean water that is easily accessible. They don’t have to fight for dirty water because they have clean water within a short distance. Their heath has improved significantly and the entire village is thankful!

What Is the Poverty Cycle?

Image
The question, “What is the poverty cycle, or cycle of poverty?” is one that must be answered to address and end poverty across the globe. Put simply, the term refers to the trend where the vicious effects of poverty and deprivation pass from one generation to the next, with no seeming way out. [1] Someone born into poverty has fewer opportunities than their wealthier peers. They must focus on survival above all, leaving little room for anything else. One illness can wipe out a family’s savings, but the unclean water sources and lack of protection available to them invite sickness. Walking to retrieve water can be time-consuming yet must be a daily priority, and many children must work alongside their parents for the family to afford food. Thus, school is often a far-off dream. Having had few opportunities to acquire skills, the kids grow up to repeat the cycle of poverty with their own children. This story was all too familiar for Nalah. His father worked in the tea fields, trying to e...

What Do I Need to Know about the Global Poverty Rate?

Image
Statisticians are getting better at measuring the global poverty rate every year. The World Bank is one group working hard to accurately measure it so that the extent of the problem is fully known and so that progress can be measured. [1] Through governments and non-governmental organizations (NGOs), we can more clearly see the last decade of progress and the most recent effects driving poverty rates. Sub-Saharan Africa has been one area difficult to measure, but new data shows an overall reduction in the percentage of those in poverty. Unfortunately, there is an increase in total number of people living at or below the official poverty rate of $1.90 per day. [2] That doesn’t mean that all hope is lost. With good statistics and a clear view of the problem, countries and organizations can use the proven methods to regain any ground lost. Additionally, valuable lessons have been learned about how to protect the most vulnerable and how to prevent some of the worst effects. GFA World is un...

Generational Poverty: A Cycle Not Worth Repeating

Image
The cycle of generational poverty can seem impossible to break. Children inherit what their parents teach and show them. a joint report from Ascend: The Aspen Institute and Bernard van Leer Foundation affirms this. “What young children learn from the adults who raise and care for them lays the foundation for future social, emotional, language, and cognitive growth,” the report says. 1 Children raised in a generational poverty mindset often lack the tools they need to succeed or achieve a better life than that of their parents. As adults, these individuals often then raise their children in poverty similar to that of their own childhoods, and the cycle perpetuates. It’s a cycle not worth repeating, yet it does time and time again. For the 736 million people worldwide living below the poverty line, earning $1.90 a day or less, the focus is frequently on mere survival. 2 Children are disproportionately affected by extreme poverty, says UNICEF, as “children who grow up impoverished often...
