The aim of water security is to make the most of water's benefits for humans and ecosystems. The second aim is to limit the risks of destructive impacts of water to an acceptable level. [1] [2] These risks include for example too much water (flood), too little water (drought and water scarcity) or poor quality ( polluted) water. [1]
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 ...
The main causes of water scarcity in Africa are physical and economic water scarcity, rapid population growth, and the effects of climate change on the water cycle.

The human-caused changes to the water cycle will increase hydrologic variability and therefore have a profound impact on the water sector and investment decisions. They will affect water availability ( water resources ), water supply , water demand , water security and water allocation at regional, basin, and local levels.
The water, energy and food security nexus according to the Food And Agriculture Organisation of the United Nations (FAO), means that water security, energy security and food security are very much linked to one another, meaning that the actions in any one particular area often can have effects in one or both of the other areas.

Between 1.5 and 2.5 billion people live in areas with regular water security issues. If global warming reaches 4 °C (7.2 °F), water insecurity would affect about twice as many people. Water resources are likely to decrease in most dry subtropical regions and mid-latitudes. But they will increase in high latitudes.
The human right to water and sanitation ( HRWS) is a principle stating that clean drinking water and sanitation are a universal human right because of their high importance in sustaining every person's life.
