9/13/2023 0 Comments Fresh water![]() Trends for domestic wastewater suggest that little, if any, progress is being made towards the target of halving the proportion of unsafe discharges by 2030. Target 6.3: An estimated 58% of wastewater generated by households was safely treated in 2022, based on data from 140 countries and territories. Achieving universal coverage by 2030 will require an increase of 5 to 8 times the current rate. While the majority live in rural areas, the unserved population is decreasing in rural areas and stagnating or increasing in urban areas. Targets 6.1 and 6.2: Despite progress, 2.2 billion people still lacked safely managed drinking water services, 3.4 billion lacked safely managed sanitation services, and 1.9 billion lacked basic hygiene services in 2022. Boosting infrastructure investment, improving cross-sectoral coordination, and addressing climate change is key to getting SDG6 back on track. Achieving universal coverage by 2030 will require a 6-fold increase in current global rates of progress on drinking water, a 5-fold increase for sanitation, and an 8-fold increase for hygiene. In addition, water pollution is a significant challenge which affects both human health and the environment in many countries. Water scarcity is a growing problem in many parts of the world, and conflicts and climate change are exacerbating the issue. (Percents are rounded, so will not add to 100)Billions of people still lack access to safe water, sanitation, and hygiene, despite improvement in the provision of these basic services. One estimate of global water distribution Although rivers account for only a small amount of freshwater, this is where humans get a large portion of their water. Rivers make up 0.49% of surface freshwater. Most of this water is locked up in ice, and another 20.9% is found in lakes. The right bar shows the breakdown of surface freshwater.Only a little more than 1.2% of all freshwater is surface water, which serves most of life's needs. Almost all of it is locked up in ice and in the ground. The middle bar shows the breakdown of freshwater.In the first bar, notice how only 2.5% of Earth's water is freshwater - the amount needed for life to survive.Yet, rivers and lakes are the sources of most of the water people use everyday. Fresh surface-water sources, such as rivers and lakes, only constitute about 22,300 cubic miles (93,100 cubic kilometers), which is about 1/150th of one percent of total water. Another 30 percent of freshwater is in the ground. And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Notice how of the world's total water supply of about 332.5 million cubic miles of water, over 96 percent is saline. Of the small amount that is actually freshwater, only a relatively small portion is available to sustain human, plant, and animal life. The left-side bar chart shows how almost all of Earth's water is saline and is found in the oceans. Here is a bar chart showing where all water on, in, and above the Earth exists. ![]()
