Physical scarcity occurs when the demand of the population exceeds the available water resources of a region. Economic water scarcity occurs when water is adequate, but is unavailable due to a lack of significant investment in water infrastructure (IWMI, 2000; Rijsberman, 2006).

What are the physical and economic causes of water scarcity?
Physical water scarcity results from inadequate natural water resources to supply a region’s demand, and economic water scarcity results from poor management of the sufficient available water resources.
What is economic water scarcity mean?
Economic water scarcity is due to a lack of water infrastructure in general or to the poor management of water resources where infrastructure is in place. The FAO estimates that more than 1.6 billion people face economic water shortage.
How is water scarcity an economic issue?
Water scarcity leads to food shortages while raising commodity prices thereby hindering trade with developing economies and in the long run cause civil unrest. Water scarcity has a direct impact on rain-fed and irrigated agriculture as well as livestock, and an indirect impact on food processing industries.
What are the two types of water scarcity?
Water scarcity is often divided into two categories: physical scarcity, when there is a shortage of water because of local ecological conditions; and economic scarcity, when there is inadequate water infrastructure.
Where is economic water scarcity?
Economic water scarcity is about a unequal distribution of resources for many reasons, including political and ethnic conflict. Much of sub-Saharan Africa suffers under the effects of this type of water scarcity.
What is the economic impact of scarcity?
One of the defining features of economics is scarcity, which deals with how people satisfy unlimited wants and needs with limited resources. Scarcity affects the monetary value people place on goods and services and how governments and private firms decide to distribute resources.
Why is scarcity important to the economy?

The scarcity of goods plays a significant role in affecting competition in any price-based market. Because scarce goods are typically subject to greater demand, they often command higher prices as well.
What are the physical causes of water insecurity?
The causes of water insecurity are physical (climate variability, salt water encroachment at coasts) as well as human (over abstraction from rivers, lakes and groundwater aquifers, water contamination from agriculture, industrial water pollution.)
What economic activities depend on water?
Economic characteristics of water. Water provides goods (e.g. drinking-water, irrigation water) and services (e.g. hydroelectricity generation, recreation and amenity) that are utilized by agriculture, industry and households.
What is the economic value of water?
The economic value of water is defined as the amount that a rational user of a publicly or privately supplied water resource is willing to pay for it.
What are the different types of scarcity?

Who is most affected by water scarcity?
Women and children are the most affected — children because they’re more vulnerable to diseases caused by dirty water and women and girls because they often bear the burden of carrying water for their families for an estimated 200 million hours each day.
What are the three dimensions of water scarcity?
Three modes of water scarcity are identified: climatically induced scarcity; soil water scarcity; and blue water scarcity (both demographic and use-related scarcity).
What are some examples of scarcity in economics?

What physical factors influence water stress?

- Geology. Rainfall flows down to the rocks beneath the ground.
- Pollution.
- Over-abstraction.
- Limited infrastructures.
- Poverty.
- Politics.
- Impacts on water insecurity.
What are the effects of water scarcity?
When waters run dry, people can’t get enough to drink, wash, or feed crops, and economic decline may occur. In addition, inadequate sanitation—a problem for 2.4 billion people—can lead to deadly diarrheal diseases, including cholera and typhoid fever, and other water-borne illnesses.
What human factors cause water stress?
Human activity is a major cause of water scarcity due to the use of fossil fuels that alter climate and weather activity, as well as the rapid increase in global population consuming more water. In order to provide for a growing population, dams and irrigation systems are built to supply fresh water to remote areas.
What are the benefits of water in economic aspect?
The poor gain directly from improved access to basic water and sanitation services through improved health, averted health care costs and time saved. Good management of water resources brings more certainty and efficiency in productivity across economic sectors and contributes to the health of the ecosystem.
How water plays a major role in economic development?
Water is at the core of sustainable development and is critical for socio-economic development, healthy ecosystems and for human survival itself. It is vital for reducing the global burden of disease and improving the health, welfare and productivity of populations.
