Years ago, when you spoke about the weather, people thought you were a bore. These days, everybody’s talking about the weather, particularly here in the Western Cape. We aren’t just asking if it’s going to rain or if we can get the washing out; we are watching windspeeds clock over 100 km/h, trees toppling in roads, and infrastructure buckling under the strain.
But if you look past the immediate human cost—the tragic loss of life, the mangled vehicles, the ruined crops, and the frantic calls to insurance brokers—one begins to wonder about the “Hidden Balance Sheet.” What is the cost of these extreme events to nature?
This week, while clearing alien species like Port Jackson and Brazilian Peppers in a nearby wetland, I met a young environmental economist. It struck me then that we often view nature as a “free” backdrop to our lives. In reality, it is our most vital Natural Capital, and these storms are essentially a massive, un-billed maintenance crisis.
1. The Preventative Side: Paying the “Premium”
In environmental economics, we talk about Ecosystem Services—the jobs nature does for free, like soaking up floodwater or anchoring soil. When we neglect these, the “premium” on our natural insurance goes unpaid.
- The “Alien” Tax: Invasive species like the Port Jackson bushes we were clearing are “bad tenants.” They have shallow root systems and don’t hold the Cape’s sandy soil as well as indigenous fynbos. During these 100 km/h winds, these aliens are the first to uproot, causing landslides and blocking river channels. Clearing them isn’t just “gardening”; it’s a preventative infrastructure investment.
- Wetlands as Sponges: A healthy wetland is a natural buffer. Every hectare of wetland we pave over or allow to be choked by Brazilian Peppers is a lost “sponge” that could have absorbed the surge currently flooding our roads.
2. The Recovery Side: The Cost of “Natural Debt”
When the storm passes, the bill for “Recovery Cost” is usually calculated in bricks and mortar. But for an environmental economist, the real cost is much steeper.
- Loss of Natural Infrastructure: When a century-old tree falls, the “replacement cost” isn’t just a new sapling. It’s the loss of 100 years of carbon sequestration, bird habitat, and wind protection. To “rebuild” that service takes another century.
- Soil Erosion and Siltation: The heavy rains strip topsoil from our mountains and wash it into dams like Theewaterskloof. This isn’t just “mud”; it’s the reduction of our future water capacity. Fixing this requires massive capital expenditure in dredging—a cost directly born by the taxpayer.
- The Fauna Toll: We often forget the birds and wild animals. For rare or endangered species living in our fragile Cape pockets, a single extreme event can be the “tipping point” toward extinction. In economics, this is a loss of Option Value—the lost potential of a species we haven’t even fully understood yet.
The Verdict: A National Disaster
The National Disaster Management Centre has officially declared these recent events a national disaster. While the big insurance companies are gathering to assess the thousands of claims pouring in, we need to realize that Nature is the world’s largest insurance company, but we’ve stopped paying the premiums.
The real cost of these extreme events isn’t just the CO2 emissions or the pollution we see; it’s the rapid erosion of the natural systems that protect us. We can rush to our files to check our storm coverage, but there is no policy on earth that can payout for a lost ecosystem.
If we want to survive the next “100 km/h” week, we have to start investing in the preventative side—clearing the aliens, protecting the wetlands, and respecting the economics of the earth. Otherwise, the cost of recovery will eventually become more than we can afford to pay.
