Permaculture in the tropics, cloud rainforest

Hi Zach,
We are volunteer educators working in the epicenter region of a large earthquake that destroyed many villages.  After starting the areas first high school we are now looking to expand our educational initiatives into organic farming. Unfortunately in the midst of such amazing biodiversity ALL farmers in the region use tons of insecticides/funguscides, etc in order to combat the plethora of bugs and other things that pose a threat to agriculture.
Does your book address situations such as ours?
Thank you in advance for your time.
Warm regards,
Tomás Enrique
