According to World Health Organization (WHO), 1.2 billion people have a lack access to safe and affordable water for their domestic use (2003). The inadequacy of safe and affordable water like this, can be acknowledged as water shortage or water scarcity. In one approach, water scarcity has been interpreted as a problem of there not being enough water in aggregate terms or in per capita terms (Anand, 2007). Since there is no commonly accepted definition of water scarcity, roughly certain areas qualifies as water shortage area depends on how people’s needs are defined, what fraction of the resource is made available, and temporal-spatial scales used to define the shortage. Almost one quarter of the world’s population are living on physical scarcity…show more content…
By the age of invention, problem such a water shortage supposedly clear enough to be solved and no longer become a global threat. Technology will be the answer to reduce the threat of global water shortage and invite all the people to use water wisely in order to avoid the scarcity of water. However, technology that still not affordable to be implemented in treating the global water shortage, is inhibiting the effort to reduce the water shortage and let the problem keep increasing. Whether it would affect the environment, or the people, or probably costs highly. For example, seawater desalination will be one of the answer from modern technology, but it has really expensive price. According to Anand (2007) with the very expensive price of desalination, countries seem like take it as a last resort. Beside, this invention still have the negative impact to the environment itself. Desalination plants can increase the salinity, increase the temperature and will increase the seawater temperature, decrease the saturation and concentration of oxygen, increase chlorine concentration, and un-ionized the ammonia (Mohamed, 2005). All of that aspect may possibly affect to the ecological system of the ocean. It seems like we are willing to solve one problem but create another problem. This technology that is not affordable is strengthening that the threat of global water shortage is real, and the modern technology still have no power to solve it. Another example will be dam technology. Dam is a barrier that impounds water through and also can be used to collect water for storage of water which can be evenly distributed between locations. However, dam has negative impact for not just the environment, but also to the society (Anand, 2007). Critics of dam argue that while benefit of dams are easy to estimate, costs such as impact on displaced population and environmental impacts on submerged areas are often
