Soil erosion is one of the biggest land degradation issues plaguing the current world. I’ve touched on this topic in the land degradation series. However, a recap is warranted:
- Today, we are losing 30-40% of the world’s arable soil due to erosion every year, according to FOA.
- That is equivalent to 3 football (soccer) fields worth of topsoil every minute.
- At this rate, we will be able to practice agriculture only for 60 more years, according to a Scientific American article.
You would think that this has been a problem only since we have started changing age-old agricultural practices by using chemicals and mass producing grains to feed the growing population. However, that is not true…
Civilizations of the past have all faced the problems of soil erosion and have actually fallen because of this. That’s right: civilizations have fallen because of soil erosion. Not war, not disease but lack of soil.
