In 2018, ecologists Rebecca Cole and Rakan Zahawi from the University of Hawaiʻi at Mānoa spread about 30 truckloads of coffee pulp over a half-meter-thick layer on a degraded cattle pasture in southern Costa Rica. The pulp, a waste product from coffee processing, was intended to suppress invasive African grass species that had created a barrier to forest regeneration.

Por que importa

Two years later, the treated plot showed 20 times greater woody stem density, 30 times greater basal area, and a canopy cover exceeding 80 percent, compared to only 20 percent in the untreated control plot. Some young trees reached 4.5 meters. The researchers attributed the success to the thick pulp layer smothering and “cooking” the invasive grass rhizomes during the dry season, while enriching the soil with carbon, nitrogen, and phosphorus.

The experiment highlights a potential low-cost method for tropical forest restoration using agricultural waste. However, the researchers caution that the method is site-specific and could pose risks of water pollution or promoting invasive species in other ecosystems.
