A nature-based soil security solution is proposed. In countries with active volcanoes, such as Indonesia, volcanic ash could be used to supply nutrients and reduce CO 2 from the atmosphere. The weathering can draw CO 2 from the atmosphere; in addition, volcanic ash with 0% carbon can turn into soils with around 10% organic …
