March 22 – World Water Day 2018
HOW CAN WE REDUCE FLOODS, DROUGHTS AND WATER POLLUTION? The Answer is in Nature.
We need to preserve the ecosystems that give us water with good actions such as planting trees, not deforesting and preserving clean waters.
We have to plant trees to restore the forests. We have to reconnect the rivers to the plains and also restore mangroves and wetlands. In summary, it is necessary to analyze the circumstances to continue and produce water!
MARCH 22, World Water Day was created by UN to value the importance of water. This year’s theme is ”Nature for Water”. Nature has the solutions to the challenges of the 21st century.
HEADLINE FACTS
Water Demand:
- 2.1 billion people lack access to certain groups of passengers and water to drink.
• By 2050, the world’s population will have grown by an estimated 2 billion people and global water demand could be up to 30% higher than today.
• Agriculture currently accounts for 70% of global water withdrawals, mostly for irrigation.
• Industry takes 20% of the total, dominated by energy and manufacturing.
• Domestic use takes 10% of water, with less than 1% for drinking water. Industry takes 20% of the total, dominated by energy and manufacturing.
Water Availability:
• Today, around 1.9 billion people live in potentially severely water-scarce areas. By 2050, this could increase to around 3 billion people.
Water Quality:
• An estimated 1.8 billion people use an unimproved source of drinking water with no protection against contamination from human feces.
• Globally, over 80% of the wastewater is generated by society flows back into the environment without being treated
or reused.
• By 2050, its population has increased and therefore the humidity will also increase. If some calculations or the increase can be more than 30%.
• Agriculture is a water-consuming activity.
• Overall, more than 80% of the waters we use go back to the environment without being treated or reused.
Climate and Environment:
• The number of people at risk of flooding is projected to increase from 1.2 billion to about 1.6 billion by 2050 – about 20% of the world’s population. Today, about 1.8 billion people are affected by land degradation and desertification. At least 65% of the forest land is in a degraded state.
About 64-71% of wetlands and natural areas have been lost since 1900 as a result of human activity.
• Soil erosion of land loaded with 25 to 40 billion tons of soil every year, harnessing crops and soil capacity to regulate water, carbon, and nutrients. The flow, which large nitrogen and phosphorus, is one of the main indicators of water pollution.
