Question

what role can we play to overcome water problem​

Answer 1

Answer:

Water is the source of life. This precious resource covers more than two-thirds of our planet. Still, the amount of fresh water is limited and constantly threatened by human activities and climate change. According to the UN, fresh and readily accessible water which is found in rivers, lakes, streams, wetlands, and aquifers, makes up only 2.5% of all water on the planet.  

In order to address key water challenges and raise awareness on the importance of water, each year on March 22nd, we celebrate World Water Day. This year, the special focus is on nature-based solutions as a response to key water challenges we face in the 21st century. Therefore, the official theme of the World Water Day 2018  is “Nature for Water”.

Explanation:

Key Water Challenges

We depend on fresh water in every aspect of our life. We use fresh water for drinking, sanitation, recreation, farming, energy production, and industry. Since the global population constantly grows, the demand for fresh water will also increase. By 2050, it’s predicted that the demand for fresh water could be 30% higher.

Besides the increasing demand for fresh water, key water challenges we face in the 21st century include:

Water scarcity and pollution which cause reduced access to safely managed drinking water and sanitation services

Water-related natural disasters (such as floods and droughts)

Climate change which causes the movement of salt water into fresh water aquifers

Water-borne diseases (i.e. diarrhea, one of the main cause of mortality)

Increased food and energy production which significantly increases water withdrawal

Nature: The Answer to Water Challenges

Humans are not the only living beings who depend on water. Fresh water is an essential component of natural ecosystems as well. In order to preserve the planet for future generations and protect natural ecosystems, World Water Day highlights nature-based solutions to overcome water challenges. These include:

Planting trees and new forests

Reconnecting rivers to floodplains

Restoring grasslands and natural wetlands

Creating buffers of vegetation along watercourses

Practicing sustainable use of water in agriculture and industry
