The top photo shows the border between Haiti and the Dominican Republic (Haiti to the left). The entire country has been stripped of vegetation to provide cooking fuel.
On the left you can see a woman in Africa using a solar oven. There are many designs for these, and I can imagine one made of hinged metal that is collapsible for nomads.
I have been trying for years to get the Red Cross, Oxfam, etc. to start distributing solar ovens in Haiti, and anywhere else where there is plenty of sunshine and shrinking forests. Funny thing is: NGOs seem to like "projects" that don't solve a problem; they would rather treat a disease than cure it. It's called "job security".
