Identify and explain what can be done to reverse some of the threats posed by a lack of water availability in certain parts of the world.

Answer and Explanation:

Definition of Terms

Lack of water availability is a natural situation that occurs where and when water becomes scarce and not readily available for use.

Possible Threats

Most of the threats caused b water lack of water availability are caused by human activities both necessary and unnecessary while others are caused by nature responding to some of those human activities. These threats include pollution, change of landscape, urban growth, deforestation and climate change.

How to reverse these threats

Implementing adequate hydrologically-based water assessment and management processes:

Landscape changes which are inevitable, are of different types and therefore poses different specific impact on the ecosystems directly or on water availability indirectly. The strength of the impacts will vary with a wide range of possible landscape changes depending the settings conditions. For this reason, it is imperative that for certain parts of the world where the threat of water availability is experienced that adequate hydrologically-based water assessment and management processes be implemented.

Developing optimum, scalable and energy efficient plants for desalination:

For man ears desalination has helped solved lack of water availability in certain parts of the world, but these desalination plants are energy-intensive. However, with newer technologies, these plants would require less energy and when utilized would reverse the threats posed by lack of water availability.

Innovative water catchment and harvesting:

Water catchment systems are imperative for areas with lack of water availability in order to store more waters as gotten from other sources where it is readily available, whilst also recycling the waste waters in those areas too.

Better policies and regulations while educating the masses:

Lack of water availability would affect food security and even cause pollution, therefore the government would need to make better policies and regulations guiding the use of water whilst educating the masses on the need to change their water consumption and lifestyles. And this is easily done when the water available is appropriately priced.

Holistic Ecosystem management:

This type of management means taking into account the ecological, economic and cultural goals that affects the country's natural resources, and this approach has to be holistic, logical and practical. Why holistic approach? Simply because each aspect is related to and influenced by the others.

Improved Distribution Infrastructure:

Poor infrastructure poses threats to health and even the nations economy. The infrastructural system in place for waver distribution must be of good quality and constantly checked and maintained.

The above stated approach would reverse lack of water availability in any nation.
