Tragedy of the Commons - How the scramble for sand is destroying the Mekong
22nd December 2019
AQA chose sand as a topic in a recent A-level economics exam. Here is classic example of a common access resource being over-exploited as it inevitably will be.
"In the last two decades demand has increased threefold, says the UN, fuelled by the race to build new towns and cities.

China consumed more sand between 2011 and 2013 than the US did in all of the 20th Century, as it urbanised its rural areas."https://t.co/C30EerTUBU
This is a fantastic story that has a variety of angles - you could start by highlighting that it ties in with the rise of China, because China's demand for cement is driving the demand for the sand from the Mekong river's banks.
However, the real interest in the story is about how to protect increasingly rare riverbank sand, and how the market is operating to encourage the use of alternatives like desert sand in the creation of alternative building materials. You might start by thinking about how property rights could play role in resolving the issue.
The banks of the Mekong River are collapsing & half a million people are at risk of losing their homes due to the world's insatiable demand for sand. 50 billion tonnes of sand are dredged globally every year - the largest extractive industry on the planet
