<p class="MsoNormal">>The preferred wood in Botswana does not coppice.<br>
<br>
The reason people may be unlikely to want to use coppiced (almost all low density) wood for cooking is they want to leave the fire for 20 minutes without attention, at a time minimum.<o:p></o:p></p>

<p class="MsoNormal">In Indonesia thin sticks are frequently used for cooking and they can only leave the stove for 5 minutes, approx. There is a strong preference for ≈20 minute attention gap in places where the staple food has to be left alone.

<p class="MsoNormal">I was given the example of collecting water from a standpipe as something that takes “about 20 minutes” as a motivation. Taking care of small children is another. In other countries cooks had given ‘preparing the food’ (chopping veggies)
as a task that takes from than 5 minutes, given to emphasize a desire to extend the time between attendances at the stove.<o:p></o:p></p>

<p class="MsoNormal">Slow growing acacias with a diameter of >50mm are great for providing a 20-40 minute moderate fire that does not need attention.<o:p></o:p></p>
