Badlands are generally unsuitable for agriculture, but attempts have been made to remediate badlands. For example, reforestation is being attempted in the Garbeta badlands of Eastern India. Revegetation and reforestation have been studied in the black marl badlands of the French Alps. Austrian black pine can become established and then be gradually replaced by native deciduous species. However, the time scale for this process is many decades.
