Wally commented on Kalimantan Haze Shelter Program

Hi Irene!

Here’s a little video we did a while back to explain the Haze to our community.

1. The haze is made up of particles that become airborne during forest fires. The ones we focus on are sized 2.5 Microns (PM2.5).

The WHO deems this sized particle important to keep out of our respiratory system because they are small enough to enter our blood stream and cause long term health issues like cancer and strokes.

So we are not focussed on gasss like CO2, but PM2.5 particles.

2. Presently, the plan is to have each family take 2 filters with them. We estimate the filters will last them about 2-3 months of PSI 300-500 conditions. But we have a team monitoring air quality at our headquarters and posting them here regularly:

We will make some estimations from the air conditions and check with our beneficiaries if the filters still have pass through. If not, we will ask them to come get replacements.

But we do have resource constraints.

Presently we have been funding the work ourselves and have limited stock of filters.

If you’d like to learn more of what we have done so far, do watch this video too:

Hi AZ!

There are two types shelters. One based in a concrete space, that’s the Headquarters we have in Indonesia.

The other is a bamboo dome structure we call the Little Nest. These are built within village houses. They do not face the outside elements.
The idea is that many villagers do not evacuate when the haze comes and choose to stay put exposing themselves to the haze filled air.

Our shelter is built in their living rooms, creating a pocket of air to have them adapt to haze conditions of about PSI 1000 and below.

So the Little Nest is not meant to withstand weather or even direct fires, they are like indoor tents that allow for clean air pockets for breathing.

We will always recommend evacuation but based on history and a long held fear of having their property taken from them, they are unlikely to escape.

Hope this clarifies the purpose of the Little Nest dome.

Hi Steve!

Agreed, pollution from combustion engines is a major concern.
In Kalimantan, due to lower population density than Jakarta, the transport caused pollution is lower, but still present.

Regulation also exists regarding forest fires, but it will take time to see if this is going to stick, as it's much harder to catch an individual tossing a stray match than catching an container carrier. :)
