It's not nature's fault

Here I was, studying Management of Natural Risks, when my family alerts me of a very real disaster going on not to far from where they live.

My mother's family is from a cute little town called Blumenau, which means Field of Flowers in German, and is one of the German towns set up by pioneers in the late 19th century in Southern Brazil. You see, these German pioneers were practical. They knew that living near a water source would help them with their early development and getting started in a new country. So they picked a site next to a large river bend, built sturdy German houses, and named the town after flowers. It couldn't get much better than that.

But Brazilian climate tends to be a little more unpredictable. Southern Brazil is predominately Atlantic rainforest- or at least it is supposed to be. There is a large annual rainfall, electrical storms, and even some tornados off east. Once the riparian forest was gone, the river started swelling and causing enormous, catastrophic floods. The first recorded flood was September 23rd, 1880. The worst ones were in 1983 and 1984. My mom was a teen at that time. She remembers the streets becoming rivers and drinking water from the neighbor's swimming pool, because it was the only potable water left. 

Unfortunately, it wasn't the last. The last one was in 2008. It killed over a hundred people and moved thousands out of their homes. Many still don't have where to live. I've seen stories on tv of people that have no idea what to do next. They shake their fists into the air, wondering why this happened to them.

While it might not be their fault that they lived in such a precarious position, it certainly isn't nature's fault. This is Brazil. This is a climate that is used to very rainy seasons that may pop up once a century or twenty times. It's unpredictable. You cannot, and must not, do anything to change that.

What you can do is to reduce its consequences. It's the first thing I learned on my very first day of class this year : Risks are there. You can't change them. Earthquakes will happen, volcanoes will spew lava, rain might fall for 40 days and cause a flood. Earth is like that. We have to learn to live with it instead of fighting it. Luckily, most of these events are predictable. The Japonese have learned to deal with earthquakes by building seismic-proof buildings. The Dutch have built dikes to keep their country from disappearing bit by bit. 

Unfortunately for those who live in Blumenau, it's very hard to deal with this particular risk. Those who live on low lands often don't have the choice of moving elsewhere. The high lands are too far from the city and there's not enough money to move away. Sometimes the solution is asking for the government to step in and offer solutions : maybe subsidizing building companies to construct other buildings on the highlands, and connecting it with a good transport system so they won't be cut off from the city. Maybe it's making a system so that those who do construct on forbidden land are penalized. What I do know is that it's necessary to create a fool-proof risk system so that accidents like these don't happen again.

Because it will rain again. And again, and again. The trees love it, and so does the entire ecosystem. What can I say? It's a little piece of paradise down there. I just hope that people will protect it and not get mad at it.
