Daadab and Dollo Ado Refugee Camps were mapped in May 2012 http://www.disruptivegeo.com/2012/05/imagery-to-the-crowd-early-results/
Here are the OverPass Turbo queries to extract the buildings, roads, and POIs done during that time.

jquery tip: attach listener to body tag
$("body").on("click", "a", function(event) {
... your custom code
.... this attaches the listener to the body, but will match against any click from an <a> tag.
.... so you don't have to attach to every a tag every time, but can use only 1 listener
... also good, because you can attach the listener to a parent element and not have to update the listners whenever a new <a> tag is created
});

On the about page is the source url CSW call:
By default GeoNode only returns at max 10 records in a csw request at a time

Use CONDA-FORGE to install OSMNX.
conda config --add channels conda-forge
If you are like me you find yourself cloning a repo, making some proposed changes and then deciding to later contributing back using the GitHub Flow convention. Below is a set of instructions I've developed for myself on how to deal with this scenario and an explanation of why it matters based on jagregory's gist.
To follow GitHub flow you should really have created a fork initially as a public representation of the forked repository and the clone that instead. My understanding is that the typical setup would have your local repository pointing to your fork as origin and the original forked repository as upstream so that you can use these keywords in other git commands.
Clone some repo (you've probably already done this step)
git clone git@github...some-repo.git
