World Water Day Quiz: How much do you know about water and refugees?

Access to safe water is a basic human right. And for refugees, it is fundamental for their survival, health, safety and dignity. 

Millions of refugees live in densely populated areas with limited access to clean water. In these conditions, practicing proper sanitation and hygiene is a constant challenge. Without clean water, refugees are at an increased risk of diseases - such as COVID-19 - that can rapidly spread among households and communities. 

Limited accessible water sources also expose vulnerable refugee groups -such as women and children who are often charged with collecting water - to harassment and sexual and gender-based violence (SGBV). Long walking distances and excessive time waiting at water points also threaten the ability of children to stay in school or for women to learn new skills -- all of which are key for rebuilding their lives.

1) A2.2 billion people – 29% of the world’s population- do not have access to safe drinking water and three billion people – nearly half of the world’s population - do not have a handwashing facility with water and soap at home. In developing countries - some of which host large numbers of displaced people- almost 75 percent lack access to washing facilities or soap.

2) B - American families use on average approximately 300 gallons of water per day at home and 70 percent is used indoors, according to the United States Environmental Protection Agency.

3) A – Four gallons per person per day is the minimum quantity required for essential activities during an emergency, but it is usually insufficient to meet regular basic hygiene and consumption requirements. The World Health Organization recommends between 13 to 26 gallons per person per day to ensure basic needs are met and few health concerns arise.

4) C- As of March 2020, 47 percent of schools worldwide lacked a handwashing facility with water and soap - affecting approximately 900 million school-age children – and at least one-third of schools did not have available spaces for children to wash their hands at all.

5) D- All of the diseases mentioned and many others - such as dysentery, typhoid, and polio - are transmitted through contaminated water. Both malaria and dengue fever are carried by mosquitoes, which lay their larvae in still water. 

6) B- More than half of Yemen’s population (55 percent) do not have access to safe and clean water and nearly half of it (45 percent) cannot afford to buy soap.
