Water issues in developing countries include scarcity of drinking water, poor infrastructure for water and sanitation access, water pollution, and low levels of water security. Over one billion people in developing countries have inadequate access to clean water. The main barriers to addressing water problems in developing nations include poverty, costs of infrastructure, and poor governance. The effects of climate change on the water cycle can make these problems worse.
The contamination of water remains a significant issue because of unsanitary social practices that pollute water sources. Almost 80% of disease in developing countries is caused by poor water quality and other water-related issues that cause deadly health conditions such as cholera, malaria, and diarrhea.[1] It is estimated that diarrhea takes the lives of 1.5 million children every year, majority of which are under the age of five.[2][3]
Access to freshwater is unevenly distributed across the globe, with more than two billion people live in countries with significant water stress.[4] According to UN-Water, by 2025, 1.8 billion people will be living in areas across the globe with complete water scarcity.[5] Populations in developing countries attempt to access potable water from a variety of sources, such as groundwater, aquifers, or surface waters, which can be easily contaminated. Freshwater access is also constrained by insufficient wastewater and sewage treatment. Progress has been made over recent decades to improve water access, but billions still live in conditions with very limited access to consistent and clean drinking water.
