No, climate change didn’t “cause 180 deaths” in Europe’s floods

Can we say “we told you so” now? Ignoring ecologists’ warnings about bad land management, and cutting government services, caused those deaths at least as much as climate change did.

Last week almost twice as many people died in floods in one small part of Germany and Belgium than die in the entire U.S. in a year of floods and hurricanes combined. Virtually all of the media and the informed public think those 180 deaths were “caused” by the climate crisis. That’s not true.

Climate change is indeed increasing the intensity and number of storms such as the one last week. But that doesn’t mean people had to die. What happened last week was exactly as though a hurricane hit New York and the building regulations only stipulated an ability to withstand 30 mile-per-hour winds, and so the skyscrapers collapsed in the 100-mph winds. The deaths would have been easily preventable, and indeed that is the case because skyscrapers don’t get blown over by hurricanes.

In Berlin, toilets flush directly into the river (but it’s not just Berlin)

Raw sewage flows into the waterways in Berlin and many other cities on a regular basis. Some are doing more about it than others.

When you flush your toilet in Berlin, it goes directly into the Spree river that runs through the city, or into one of its several canals. This happens on 30 to 40 days each year, sometimes as many as 60, whenever there’s a moderate-to-strong rainstorm. This post is a documentation of just a few of the 120-odd outlets where the untreated sewage enters the waterways.

Everything you always wanted to know about green infrastructure but were afraid to ask

Second in the EYAWTKA series. This post is an annotated and tightly edited list of resources on green infrastructure that I don’t think you can find all in one place anywhere else. It began just as some reminders to myself and then I figured maybe others might find it useful. It’s far from comprehensive but it is highly selective – for every link here, many less optimal ones were weeded out.  Specialists may want to skip to the BMP tools and databases farther down.

Green infrastructure is a set of methods for cities to prevent flooding and water pollution by using nature instead of fighting it. It’s a subset of what is often called Best Management Practices or Low-Impact Development. Sometimes it’s called nature-based-solutions or sponge city because it’s about soaking up rainwater.

Welcome to stuffy, uptight, downtown Munich. Don’t forget your swimsuit. Or surfboard. Or skis.

This is the river Isar in the middle of Munich, just blocks from the city center. Today it looks like a wild natural river but until a few years ago much of the greenspace along the shores was orderly and park-like, the banks straightened and stabilized with stone, concrete and earthworks. This is the story of how a city with a stuffy, uptight reputation (whose accuracy I neither verify nor refute) tore out the orderly, linear shores and restored the river to about as wild a state as possible in an urban center, embracing nature in all its wildness and messy, ecologically healthy vitality – something which even places that are said to be the opposite of stuffy <coughberlincough> are often slow to do.

“Usage Conflicts”: Berlin debates whether it has enough space to adapt to climate change

This post is available in German at the BUND (German Alliance for Environmental and Nature Protection), here.

To say that Berlin is lavishly endowed with public spaces that are manifestly unused despite being paved is an understatement. I’m pretty sure Berlin has more unused paved space relative to the amount of functioning space than any other major city. (If you can think of one, let me know in the comments.) I am not talking about vacant lots that could hold buildings, or any place with significant foot traffic, or squares or plazas that are actually used, or even the parking lots that exacerbate climate change by incentivizing car travel. I refer instead to the inexplicable empty stretches along buildings and at streetcorners that go unused by pedestrians, sidewalks extravagantly and desolately out of proportion to their foot-traffic load, and large traffic islands and medians.

De-paving with Operation Stonebreak

Water in cities has a critical role in climate adaptation, from bathrooms to backyards to sewer lines. An engaging exhibit in the Netherlands explains how.

 

Here’s a detour to the Netherlands, where I saw an excellent exhibit in Haarlem, at an architecture and urban design museum called the ABC Architecture Center, on how the region’s water systems will be affected by the climate crisis and how the city is starting to adapt.

Mythbusting the weather: Berlin’s rainy reputation belies a grave lack of water

Despite its abundant waterways and reputation for rainy weather, Berlin is in many ways as dry as Spain or Texas. Meanwhile, hundreds of millions in fines are looming due to ongoing violations of E.U. water protection law. Solutions will be tough: Berlin has 13 mayors and a bizarre water supply system, the only one of its kind in the world.


Berlin is always seen as a watery place: everyone loves the abundant rivers, canals and lakes and hates the grey damp winter; panic – much of it unfounded – over basements flooded by a high water table is something of a municipal religion. The surprising truth, though, is that Berlin is a very dry place with dried-up forests, shortages of water, and extremely low rainfall, in fact less rain than parts of Spain, Italy, and pretty much all of the United States including Texas and Florida, apart from the deserts and parts of California. The climate crisis did not cause any of this, but it’s making everything worse.

Drought risk. Berlin is rated medium-high (red, 4 out of a maximum possible 5), along with Cuba, Haiti and eastern Mexico. “Drought risk” factors in population density and demand for water along with supply of water.

In Indianapolis, trailblazing environmental art once connected the public to their overlooked waterways. Then they turned the art museum into an Instagram playground.

From 2010 to 2015, over 100 engaging and innovative land-art installations in Indianapolis raised public awareness of river ecology and water infrastructure. But the once-prestigious museum behind them has since pivoted to crass marketing gimmicks – yoga, craft beer – and the “greatest travesty in the art world in 2017”.

 

FLOW 19L

 

There’s a famous story by Borges about a map that’s so detailed, it’s as big as the territory it describes. A few years ago, the artist Mary Miss actually made such a map out of metal and mirrors as way to build closer and more thoughtful connections between its residents and their waterways.

It was actually two projects, FLOW – Can You See The River? (2011) and StreamLines (2015). They consisted of over 100 giant oversize map pins with bright red basketball-size pin heads placed throughout the city to mark various features of the local urban waterways such as small dams and sewer outlets. The goal was to increase the public’s connection with the natural urban environment, specifically rivers, streams and water infrastructure. Further, every site had an ingenious interactive installation that not only provided multimedia information about the water features, but literally, physically engaged the viewers by involving bodily movement and play. A worlds-first phone app called Track a Raindrop provided user-friendly visualizations of how stormwater travels through the city infrastructure.

Leipzig’s urban streams, once buried in concrete, are seeing the light of day

Restoring degraded, concrete-encased urban streams is essential for healthy ecosystems and resilience to the coming impacts of climate change. In this area, the eastern German city of Leipzig has been busier than most.

 

The city of Leipzig, once home to Bach, Wagner and Mendelssohn and in 1989 a crucible of sorts for the Peaceful Revolution that led to the reunification of East and West Germany, has made itself a world leader in urban stream restoration over the last two decades, very much under the radar. Since the late 1990s the city has been reviving streams and canals that have been buried in underground pipes and paved over for the last 50 years, or simply silted up with mud, both in the city center and surrounding countryside. The formerly sooty, crumbling city core is now crisscrossed by tidy canals that, despite their intensely un-natural urban context and industrial history, are intended to provide at least some of the functions of natural streams.

Outside the city, no less than 26 lakes created by the closure of all but one of the area’s open-pit coal mines are being natur-ized (it’s not restoration per se because they were never natural lakes) and connected by natural and artificial waterways and locks to create a region-wide network entirely passable by small recreational boats and, it is hoped, fish.
