Mangrove soils have unique properties, able to transform and sequester chemical compounds of biogeochemical and ecological importance, including heavy metals. The degeneration of mangrove soils shows the risk of releasing these metals to the environment. We search for improve the knowledge about how disturbance affects the metal fixation and microbial of mangrove soils. This study characterized a mangrove soil along the Graciosa River estuary (Bahia, Brazil), according to selected physical, chemical and microbiological properties. In 2002, soil was collected from an anthropic and from an adjacent natural site. Both sites were re-sampled in 2007, after a vegetal regeneration on the anthropic site. Significant differences between the natural and anthropic surface layers were observed for chemical and physical soil properties. In particular, heavy metals (Co, Cr, Cu, Zn, Ni, Mn and Fe) showed significant differences with depth and lower concentrations were found in the anthropic site, exception to Cd (moderately high). Between 2002 and 2007, the disturbed site showed a decrease for all observed metals, except for Ni. The data also suggest that microbial populations may be favored in the layers of the soil profile most influenced by high and low tides, C1 (0-20 cm) and C5 (99-125 cm). |

Motivation: The combination of institutional weaknesses, climate change, and overexploitation is increasingly recognized as endangering the Amazon forest. These three factors made 2020 the worst year for forest fires recorded in the previous 60 years. We analyse environmental policies across the nine countries of the Amazon Basin to develop national and regional forest programmes to tackle this scenario. Purpose: The study synthesizes and compares key environmental legislation concerning protected natural areas (PNAs) and fire management in the nine countries of the Amazon Basin. To this end, the research question asks what directions can be drawn from a visualization and compilation of national regulations for future policy research and practice. Methods and approach: We undertake a critical literature review of PNAs and fire-management policies across the nine countries of the Amazon Basin and their further alignment using analyses of previous policy reviews on forest codes and land distribution. Findings: The article shows the heterogeneity of national fire-use and fire-management policies among the nine countries of the Amazon Basin. In addition, it suggests that top-down policies and regulations are likely to be characterized by misunderstandings (either direct or indirect) of local practice, rationale, and capacity; and, in some cases, risk criminalizing local and indigenous daily subsistence. Policy implications: The study indicates the need for more in-depth research and policy on participatory governance platforms for the use and management of fire, rather than fire-suppression and fire-risk adaptation strategies. There are some positive, albeit often isolated, cases, to which scholars, policy-makers, and environmental practitioners should pay more attention.
