Population is the number of inhabitants (in our case, human) in a
specific region (Dictonary.com 2018) . Global population is now about 7.4  billion and we should remember that despite
the fact that world is unevenly distributed, every minute the population is
growing. Although there are regions where population decline or change in
structure caused by the births, deaths and migration. Population will decline if
death rate is greater than birth rate
and will increase if death rate is less than
birth rate.(BBC 2014).

Human population change is the
difference between the size of the population from the beginning to the end of
a certain time period. In other words, population change refers to change in the number of people during a
specific time period (Wikipedia 2014). There are both positive and negative
consequences of population changes. To positive consequences, could be counted
increase of innovation in growing regions. What is more if the population
growth, education and medicine develops so that society becomes healthier. There
are also lots of negative consequences such as political conflicts or air
pollution.

Water has very important role
in our life’s and there is no organism in the world that does not need water that’s
why water scarcity is one of the negative consequences of population change. Water scarcity is the lack of sufficient available fresh
water resources to meet water demand. (Wikipedia
2018). There are two types of water scarcity: economic and physical. Physical Water Scarcity: Where the demand for water is greater than the supply
of water. Physical water scarcity does not have to be an arid environment,
because there demand for water in arid environments (deserts) is not normally
low meaning that there is no shortage. Economic Water Scarcity: Where there is water available, but for some economic
reason it is not possible to fully utilize the source of water. This might
because extraction or transportation costs are too high, or because the water
is polluted and it is not possible to treat it. (Greenfieldgeography 2018)

Yemen is a Middle Eastern country that’s currently
experiencing political and national strife. When turmoil brews, resources are
often brought to a halt. Certain parts of this country are run by terrorist
groups, making it difficult for citizens to get the aid they desperately need.
One of these scarce resources is water, as Yemen’s geographical layout doesn’t
yield many natural sources. As a result, it uses aid and other sources for
support. However, the current state of the country prevents these resources
from reaching the hands that need it most. According to UPI, Yemen’s capital,
Sanaa, is expected to be the first major city in the world to experience full
water scarcity.

The country of Jordan is located in one of the driest
regions in the Middle East, meaning that water isn’t exactly easy to come by.
However, their neighbors are no better off – many countries that surround
Jordan also experience water scarcity. As a result, Jordan often turns to its
two natural resources: the Jordan River and the Dead Sea. However, it costs
money and time to convert salt water to fresh water, and Jordan doesn’t have a
lot of those resources, considering its economic and political state. The
country’s population is also continually growing and those two resources are evaporating
more and more, leaving Jordan with very few options(The university of Arizona 2016).
