Biomass Increase

Native species may have adaptive traits that are advantageous for overcoming the adverse environmental conditions faced during the early stages of mine land rehabilitation. Here, we examined the nitrogen (N) growth responses of two native perennial grasses (Axonopus longispicus and Paspalum cinerascens) from canga in nutrient-poor iron mining substrates. We carried out vegetative propagation and recovered substantial healthy tillers from field-collected tussocks of both species. These tillers were cultivated in mining substrates at increasing N levels. The tillering rates of both species increased with the N application. Nonetheless, only in P. cinerascens did the N application result in significant biomass increase. Such growth gain was a result of changes in leaf pigment, stomatal morphology, gas exchanges, and nutrients absorption that occurred mainly under the low N additions. Reaching optimum growth at 80 mg N dm−3, these plants showed no differences from those in the field. Our study demonstrates that an input of N as fertilizer can differentially improve the growth of native grasses and that P. cinerascens plants are able to deposit high quantities of carbon and protect soil over the seasons, thus, making them promising candidates for restoring nutrient cycling, accelerating the return of other species and ecosystem services.

Historical records of socio-environmental impacts related to large-scale iron ore development in Brazil are driving different planning approaches in the burgeoning iron mining and smelting complex of Corumbá, located at the border of the Pantanal ecosystem in the Brazilian state of Mato Grosso do Sul. Among the most relevant efforts are two strategic environmental assessments (SEA): one was led by a mining company and the other by a civil society committee. This paper assesses to what extent these SEAs can contribute to the mitigation of negative socio-environmental impacts of the Corumbá Complex. It also evaluates if the SEA methodologies meet a number of SEA Performance Criteria. The analyses, which were based on literature reviews and content analysis of the SEA documents, reveal that the two SEAs represent an important effort to incorporate environmental variables into more strategic levels of the Pantanal region's planning. Nonetheless, both SEAs have serious limitations, given that they are not formally nested in governmental policies, plans and programmes.

A Company

In 2011, a company named Gogebic Taconite (GTAC) formed in order to develop the largest open-pit mine in the world—just upstream of the Bad River Band’s reservation on Lake Superior. Owned by Cline Resources Development (a company largely focused on coal), GTAC announced that, even without experience in iron mining, it would mine and process Wisconsin’s taconite ore body to take advantage of Asia’s building and steel commodities boom. The mine would have been sited just upstream of the reservation boundary, and the waters flowing out of the mine site would have contaminated water, fish, and Indigenous communities living downstream. After a multi-year battle, the tribe managed to stop the mine.
