They say "a picture is worth a thousand words", and these pictures are proof. They are all trees planted by AIR, and they are 4, 8, and 12 years old. It demonstrates how barren mountainsides, prone to mudslides during the rainy season, can be restored to lush, beautiful forests. AIR technicos work with Mayan farmers for 5 years teaching the principles behind reforestation, and enlisting them as partners in improving life for themselves and their community. Some farmers have started their own tree nurseries which becomes a small business for them as they sell seedlings to their neighbors. Another aspect of AIR is stove building. The cook stoves are wood burning as is the Mayan tradition. The AIR designed stove uses far less wood than their traditional way of cooking, and they are vented to prevent inhalation of smoke, thus improving health. The lady of the house is consulted about the height and location of the stove, and later it will be a gathering place for the family.AIR has a curriculum in many schools that teaches agro forestry and sustainable farming. They offer scholarships to students to ensure that the principles can be carried on into the future. I have been privileged to volunteer on three AIR mission trips, and will continue to support this wonderful organization.
