UNESCO Exploring Underwater Mayan Heritage

Guatemala is a gorgeous country with a rich Mayan history, particularly around Lake Atitlán (and the more famous Tikal). The country will now be home to a UNESCO project toking at best practices for underwater archaeology. The main idea is to work with the local population to ensure cultural sensitivity and to match that care with environmental concerns. When the practices are outlined UNESCO will expand their underwater archeology knowledge to the world’s researchers with some locations already identified.

UNESCO’s technical mission to Lake Atitlán (southwest of Guatemala) will take place in the autumn. It will be funded by Spain and will be carried out by the experts of the Scientific and Technical Advisory Body of UNESCO’s Convention on the Protection of the Underwater Cultural Heritage. María Helena Barba Meinecke, head of the Yucatan Peninsula underwater heritage programme of Mexico’s National Institute of Anthropology and History will lead the mission, which will examine the archaeological sites in the lake and propose a management plan in consultation with the local communities, for whom these vestiges are of great cultural importance.

Several submerged archaeological sites were discovered in 1996 in Lake Atitlán, the deepest lake in Central America. Among them is a Mayan villages known as Samabaj, which retains the remains of domestic structures and religious monuments. The village appears to have been built on an island that was submerged, possibly because of a volcanic eruption, a landslide or another natural disaster.

Turning Homes Into Business Could Save the Suburbs

the suburbs

The suburbs are an energy-intensive housing solution that started in North America and has spread worldwide. The appeal of the tract housing the very thing that makes the suburbs detrimental to society: large lots, expansive houses, low density, and that they are reliant on individual use automobiles. With the mounting pressure of rapid climate change and urbanization of civilization what can we do to negate the poor planning of the suburbs? One solution is to rezone the suburbs to allow business to operate to make the neighbourhoods liveable.

It’s not specifically the built form of the suburbs that makes them unappealing; the buildings there—the houses—are perfectly fine. What deadens these areas is the homogeneity of the uses these buildings are put to. But a building that looks like a house can easily be altered and put to another use. Toronto’s two most iconic and walkable neighbourhoods, Yorkville and Kensington Market, were created like this 100 years ago. If the City took away restrictive zoning, suburban areas will change as local people set up stores and services in converted single family homes and these neighbourhoods will develop organically into complete and vibrant communities.
…
The permit office should parcel out permits to create a situation where you can go six blocks in any direction anywhere in Toronto and find one or two services. For instance, from my house in North York, you have to walk 12 large suburban blocks to get to the only services available, at Bayview Village. Why isn’t there a little ice cream store or cafe on the first floor of one of the brand new townhouses built across from Bayview Village Park, six blocks away? My home has a walk score of 38 out of 100. Gradually, the City should rezone wherever necessary until every home has a walk score of at least 50. The point isn’t to make all of Toronto like downtown or Kensington Market; just add reasonable access to services that will benefit the neighbourhood. The suburbs would still be the quietest neighbourhoods with the most green space, but they would be better off by virtue of a few local amenities. If a neighbourhood wanted to opt out of this scheme, it could cease issuing these permits altogether, or, alternatively, request that the City issue more of them and to try becoming a new Kensington Market.

Farming for the Future on the Roofs of Hong Kong

fruit store

Green roofs are great for collecting water and cooling neighbourhoods, they are also useful for feeding their local communities. In the densely built urban environment of Hong Kong there is a network of green roofs that used for farming. These farms are used to grow crops sold in local stores and to encourage the people of Hong Kong to get their hands dirty and understand where their food comes from.

Here the team tell me about their other goal: education. By running regular workshops, the team hope that Hong Kong’s city-dwellers will become a little more aware of the resources needed to grow the food they are eating. Pointing to a bed of broccoli, for instance, Hong remembers one recent group who had never seen the whole plant. “They didn’t realise that the florets that we eat are actually quite limited,” she says. “And if you look at the quantity we see in the supermarket, you begin to see how much space we would need to grow that,” she says.
…
Ultimately, Tsui’s dream is that a restful break on a rooftop farm will become ingrained in everyone’s daily routine. “I use the analogy of coffee,” says Tsui – something that was once a luxury, but which became a lifestyle, through sheer convenience. If he had his way, a trip to the farm would be as essential as a morning caffeine fix. “We do have a mission, in a way – to make farming cool.”

Waterproofing Cities for Resiliency

housing

The last month brought a lot of rain to the city of Toronto which has led to the Toronto islands being half submerged and a temporary (and lax) travel ban to be put into effect. The rest of the city has fared slightly better. The city has slowly been improving its water management over the years by implementing green roofs and providing more green space along ravines to absorb water. That’s not enough to deal with the increased rainfall from climate change. Over at the CBC they have an article looking at effective ways that Toronto is already using and what more can be done.

Of course, the techniques used in Toronto can be applied to many other cities.

The water that makes it past collection systems or soaks through green spaces ends up in Toronto’s sewer system.

In cases of a heavy downpour, that can send a mix of storm and sanitary water into Lake Ontario, due to the city’s combined sewer system.

While the city has dedicated reserves for storm water, it has no choice but to pump the mixed sewage and storm water into the lake during extreme rainfall.

Kids are Really Good at Detecting Bullshit

kids

Parents already know this.

Kids are really good when it comes to detecting bullshit health claims according to a new study on health. Kids were asked if certain health claims are true or not and the kids were remarkable good at deciphering bogus claims when they thought about it. The bullshit being referred to here is inline with Harry G. Frankfurt’s take on it from his academic essay On Bullshit. Basically, a bullshitter is just trying to persuade their opponent with no regard with what is true (a liar on the other hand knows the truth and is purposefully denying it).

So all those bad articles you see on Facebook claiming to ‘cure’ or ‘heal’ something – see if it fools a kid before you believe it.

In a short time, they were running their own blinded, randomized trials — the gold standard for testing medical claims — in the classroom. By the end of their experiment, Oxman said, “They figured out that there was little if any difference in the effects of the different colors and they asked me if the teenagers who made the claim really believed that.”
…

The results of the trial were just published in the Lancet, and they showed a remarkable rate of success: Kids who were taught basic concepts about how to think critically about health claims massively outperformed children in a control group.
