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. Unsound water management in violation of European Union law is incurring punitive measures, but the issue is virtually unknown to the general public – and complicated by Berlin’s strange water system, the only one of its kind in the world.


Berlin is always viewed as a watery place: everyone loves the abundant rivers, canals and lakes, and hates the grim rainy fall and winter and the high water table that poses constant and costly flooding problems to basements and construction projects. The surprising truth, though, is that Berlin is a very dry place with dried-up forests, near-shortages of water, and extremely low rainfall, in fact less rain than parts of Spain, Italy, and most of the United States including Texas and Florida. The only places in the U.S. that get less rain than Berlin are the deserts, the Mediterranean zones of California and parts of the Great Plains. The climate crisis did not cause any of this, but it’s making everything worse. (more…)

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

Over 100 engaging and innovative land-art installations 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

 

Two of the country’s most compelling and pioneering installations of site-specific environmental art in decades – as much community outreach as art per se – took place in Indianapolis, of all places, in the mid 2010s. The two projects, called FLOW – Can You See The River? (2011) and StreamLines (2015), 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.

Long buried in concrete, Leipzig’s urban streams 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.
