Is the world getting saltier?
Yes it is! And here is some of what it means:
Around 20% of all the arable land in the world is irrigated. And around 20% of all the irrigated land suffers from salinization. We lose 1.6 million hectares this way every year.
With Climate Change and rising sea levels, the saline seawaters are pushing harder to infiltrate onto land and aquifers. Urban freshwater resources are getting increasingly saline due to seawater intrusion, activities in neighbouring rural areas, and improper management of human waste. Cities, now, have to spend more on water treatment and supply, making water (and everything else) more expensive.
This video seeks to understand the problem of increased salinity from the experts’ point of view, highlighting the importance of drainage, desalination solutions, and proper agricultural water management.
