We See Seashores Shifting With Satellites

We See Seashores Shifting with Satellites

If you’re like us, as soon as the summer Sun is out, you start feeling – well, just beachy, sand you very much.

Lots of our favorite beaches are inside protected marine areas, which are regulated by governments to keep their ecosystems or cultural heritage intact. If you beachcomb at Cape Cod, swim in the Florida Keys or learn about Hawaiian culture at Papahānaumokuākea Marine National Monument, congrats! You’ve visited a protected marine area.

But time and tide haven’t been kind to some protected beaches.

Beaches are constantly changing, and science teams are using our 30-year record of Earth images from the NASA/USGS Landsat program to study what’s happening.

Overall, the sum total of sandy beaches has increased a bit over the last 30 years. But time and tide haven’t been as kind to our protected beaches – the team found that more than 1/3 of sandy beaches in protected marine areas have been eroding away.

Some of these areas were designated to protect vulnerable plant and animal species or connect delicate ecosystems. They are home to humpback whales and sea turtles, reefs and mangroves that protect the land from erosion and natural disasters, and species which are found in only one habitat in the world. Losing land area could upset the balance of these areas and endanger their future.

Next step: Looking for pearls of wisdom to save the beaches!

Right now, we aren’t sure which beaches are eroding due to natural processes, and which are due to humans – that’s the next step for science teams to investigate. Once we know the causes, we can start working on solutions to save the beaches.

Those 30 years of Landsat data will help scientists find answers to these questions much faster – instead of using airplanes or measuring the beaches by hand, they can use computer programs to rapidly investigate millions of satellite photos spanning many years of change.

By tracking beaches from space, scientists can help keep our summers sandy for years to come.

And that makes us as happy as clams.

Tiny Houses in Urban Context

I’ve seen a lot of really great tiny home designs, and I’ve seen a lot of love from other people for those designs as well. They combine a small space, perfect for one or two people, that usually only apartment buildings design for, with the benefits of having a detached home, with a yard, and windows on all sides for more natural light.

What I don’t see is a whole lot of context, least of all in an urban neighborhood environment. These houses are often pictured in an open grassy, or forested space, which is nice for some people I’m sure, but there are lots of people who would prefer to live in a city, in pedestrian and transit friendly areas, rather than in the middle of nowhere, where you’d have to use a car to get everywhere.

There already exists an urban context for tiny homes, but due to restrictive zoning, it’s not commonplace in most cities in the U.S.

They’re called Bungalow Courts, or sometimes Cottage Courts, and basically it’s where you take two adjacent lots, and rather than having one large single-family-house per lot, you have around 3 or so tiny houses per lot, all facing a shared space in the center.

All this takes up the same space as two city lots, which are usually zoned to only allow one house per lot. But not everyone wants, or can afford a large house, so Bungalow Courts would be a perfect fit in a lot of neighborhoods that currently lack a lot of housing diversity for a range of wants and needs.

Anyway, I just thought I’d share, because I think this a really neat concept that should be allowed more places. I’d think I’d like to live in a Bungalow Court; I like the idea of having a house to myself, but I don’t need much space, and I don’t want a huge yard to maintain.

In order to make this legal to build out, zoning would need to be changed to allow 3-4 units of housing to be built on lots currently restricted to only 1 unit of housing. A big contributing factor to rising housing costs has been the over-favoring of single-family houses on large lots since the end of WWII, so not enough units of housing are being built in many cities to keep up with demand.

Legalizing more “missing middle housing” like Bungalow Courts in single-family-house-neighborhoods would help cities incrementally keep up with demand, in a way that fits nicely into existing neighborhoods.

i think one of the things i want to start learning in 2018 is how to make clothes. how do you start doing that?
