I’ve been doing quite a bit of reading lately about some of the possible solutions to global warming through carbon sequestration…. Boy, that’s a mouthful to say! Anyway, one of the topics I’ve found most interesting is the current efforts in agroforestry in Africa that are actually catching on.
Agroforestry is simply growing indigenous trees in the same fields your crops are planted in. This may sound like a strange idea for fields here in the States, but in the nations of Africa, Asia, and South America, it is a possible answer to the last few hundred years of decreased food production, soil downgrading, and even starvation.
A wonderful story comes out of the African nation of Burkina Faso where farmers were taught the benefits of agroforestry. But it had to start with education and here’s why: Since colonialism, the governments of most African nations that rule the poor farmers actually OWN every tree that grows in the country. If a farmer was found harvesting a tree, he would be jailed, fined, even killed for stealing from the state. So, being proactive, farmers would pull up the seedlings of any indigenous trees that happened to sprout in their field. Fast forward after 100 years of pulling up all the trees, and growing crops year in year out, and nations around the equator are left with are large expanses of dusty fields with little or no trees to speak of, and sub par soils. The mature trees that happen to exist are more than likely an import of some kind that is not indigenous to the area and underperform because of it.
So here’s what they did: First of all, some countries finally changed laws so that trees were more “free” to citizens. Then, the citizens had to be informed of these changes. Next, farmers learned to let the saplings of indigenous trees grow until they could take a good hold on the dirt they sprouted from. Farmers could now begin tending their crops around these trees (If you need a visual, picture sugar cane, corn, or any other green vegetation with a tree shooting up into the air every 5 meters or so). After many years of this method of Agroforestry, the results are astonishing: Higher yields across the board for vegetables, fruits, and even hardwoods. But why?
The trees growing in the fields are indigenous to the area, so they are meant to thrive where God intended them to be in the first place. And when they thrive, they grow and will help regulate temperatures on hot days by buffering a portion of the sun’s hot rays. This is especially important in equatorial countries now and in the future as the Earth continues to warm. Trees also encourage native species of animals to return to the area. Native birds can now roost in trees in the field and spend days eating pests. The bees can build hives in trees and increase pollination, and even small mammals return to reestablish the circle of life in areas where it had previously been broken.
Agroforestry in Burkina Faso is one success story that the whole world should sit up and take notice of. It has been so successful, that satellite imagery shows the greening up of the Sahel region of Burkina Faso, versus its neighboring countries Mali and Niger where the State regime still holds to the old laws that all trees belong to the state and agroforestry is a crime. But the main point is, it works to not only help feed people, but it also works to provide trees that are desperately needed to fix the ever-increasing atmospheric levels of CO2. This is the big picture item! Through this simple method of growing trees in a vegetable garden, man can ease the overall grip of climate change. It’s a nice example of how man can learn from past mistakes, and make a better tomorrow for our kids.
