Biochar has emerged over the last couple years as a ray of hope on the otherwise bleak horizon of the planet’s environmental future. It has been hailed as a possible solution to climate change, world hunger, and rural poverty — though doubts are being raised in some quarters.
Last year, some of the world’s most eminent biochar experts gathered for a biochar conference at the University of Massachusetts-Amherst to discuss this ancient technology that is getting a new look by scientists, governments and investors. To the packed audience, this promising technology sounded like a panacea for a whole host of problems. Biochar, the speakers said, could soak up large amounts of carbon from the atmosphere, supercharge soil fertility to feed the world’s hungry, promote jobs and economic opportunities for farmers, safely get rid of animal and plant waste, heat buildings greenly, and slash the kind of fertilizer use that is creating vast dead zones in coastal waters from nitrogen runoff.
