The Man Who Stopped The Desert Zai Farming Techniques by Yacouba Sawadogo

The Man Who Stopped The Desert - Zai Farming Techniques by Yacouba Sawadogo #zaifarming #yacoubasawadogo Zaï or Tassa is a farming technique to dig pits (20-30 cm long and deep and 90 cm apart) in the soil during the preseason to catch water and concentrate compost. The technique is traditionally used in western Sahel (Burkina Faso, Niger, Mali) to restore degraded drylands and increase soil fertility. Zaï holes were reintroduced since the 1980s by Yacouba Sawadogo, a farmer from Burkina Faso, who introduced the innovation of filling them with manure and compost to provide plant nutrients. The manure attracts termites, whose tunnels help further break up the soil. He also slightly increased the size of the holes over the traditional models. Zaï holes help by improving the yields of trees, sorghum, and millet by up to 500 percent. The Role of Trees In Reversing Desertification Here is a partial list of the things trees do for our planetary ecosystem: remove pollutants from our atmosphere the Portland Metro area put a value of $4.8M on the 2,000,000 lbs of pollutants removed by a tree* filter pollutants that would otherwise be carried by storms into waterways lock up carbon to reduce the “greenhouse effect” shade buildings, resulting in millions of dollars in reduced energy costs this also reduces pollution and carbon from the production of electricity required for heating and cooling provide shade and shelter in the landscape and temperature modulation for humans and wildlife shade creeks, streams, rivers, and ponds to allow fish and other aquatic species the same relief anchor riparian areas against erosion, protecting dissolved oxygen in the water allow rain water to evaporate and soak back into the ground, reducing runoff this translates into billions of dollars saved in storm water management infrastructure and construction create habitat for all manner of organisms, including songbirds who fill the sky with melody attract water in the form of rain anchor soil from eroding down slope and on flat ground due to gravity and weather feed all manner of life forms, including humans (got peaches?)
