The region is of industrial importance for its sodium and potassium. It is also being explored for the lithium brine beneath its salt, 300,100 hectares (742,000 acres) of it were awarded to LSC Lithium for development.^[2] The exploitation of lithium reserves drew criticism from Indigenous community leaders for the steep decline in groundwater levels, threatening local farming. Also, they regarded their right to have use and control over the land as violated.^[3]
