Golf courses gone wild

March 18, 2024 By EarthWise Leave a Comment

Rewilding golf courses is catching on

Golf courses are a significant burden on the environment.  The US has 16,000 golf courses which use 1.5 billion gallons of water a day and are treated with 100,000 tons of nitrogen, phosphorus, and potassium each year.  In recent years, the golf industry has taken steps to lighten its environmental toll by using less water, introducing pollinator-friendly plants, and decreasing pesticide and fertilizer use.  The US has more golf courses than any other country, accounting for 42% of all courses worldwide.

There is really an oversupply of golf courses and, as a result, more golf courses have closed than have opened since 2006.  Most closed golf courses end up in the hands of commercial or residential developers, but some of them are allowed to return to nature.

For this to happen, there has to be a willing seller and, more importantly, a conservation-minded buyer who can afford both to purchase the land and to restore it to a natural state.  There have been 28 former golf courses transformed into public green spaces between 2010 and the end of 2022.  But that number seems to be growing.

In 2023, the former Cedar View Golf Course on the eastern shore of Cayuga Lake in upstate New York was bought by the Finger Lakes Land Trust.  In California, places like Santa Barbara, Marin County, and even Palm Springs have all undertaken the transformation of former golf courses into public parklands.

Rewilding a golf course is undoubtedly a disappointment to local golfers, but it can bring big benefits to animals, plants, and people.

Fossil-free fertilizer

A fossil fuel-free ammonia plant in Kenya

Ammonia is a major industrial commodity.  About 70% of it is used to make fertilizer, with the rest for a wide range of industrial applications.  Ammonia is the starting point for all mineral nitrogen fertilizers. 

Typically, ammonia is a byproduct of isolating hydrogen from natural gas, which releases large amounts of carbon dioxide.  On a global scale, the climate impact of ammonia production is comparable to that of air travel.  The world needs more ammonia but really cannot afford the emissions that come with its production.

There are also political implications of ammonia production.  Because it relies so heavily on natural gas, ammonia supply is vulnerable to disruptions from events like the Russian invasion of Ukraine.  Sanctions imposed after the invasion have hindered fertilizer exports, driving up costs, especially in places like Africa.

A small fertilizer plant near Nairobi, Kenya will be the first farm in the world to produce its own nitrogen fertilizer on site that is free of fossil fuels.  The plant is being built by an American startup company Talus Renewables and will use solar power to strip hydrogen from water.  The hydrogen will then bond with nitrogen from the air to form liquid ammonia.  The plant will produce one ton of ammonia each day.

The typical bag of fertilizer in sub-Saharan Africa travels 6,000 miles to get there, which of course only adds to the environmental burden of using it as well as its cost.  By building a small green ammonia plant like the one coming online in Kenya, it is possible to locally produce a critical raw material in a carbon-free manner.
