International Action Needed for Reversing Brazil's Forest Code
Manifest for Brazilian mangroves
Recent amendments to Brazilian Forest Code (BFC) threatens the country’s status as the second largest mangrove area in the world (1). Contrary to major scientific advisory (2–18) and public opinion (19), government made legal for shrimp farmers and salt producers to convert tidal wetland ecosystems into ponds. Changes are being encouraged throughout the country considering BFC is a Federal regulation and applies nationally. In the Amazon biome (which comprises the coasts of the States of Amapá, Pará and Maranhão), where 60% of Brazilian mangroves are located(20), 10% of these systems can be converted. Along the rest of the shoreline, 35% can be converted. Additionally, this regulation also assures amnesty to transgressors that occupied these areas until July 22, 2008.
Assessments made prior to the consolidation of shrimp farming industry in Brazil revealed that the country had already had lost 50,000 ha between the years of 1985 and 2000 due to diverse causes(21). Nevertheless, it is estimated that shrimp farming industry alone is responsible for the conversion of another 50,000 ha of the country’s tidal wetland ecosystems into ponds (22, 23), mainly on salt flats (24).
Despite the increasing growth rate of shrimp farming in Brazil during the past decade (from 7,000 to 90,000 tonnes per year production), its CO2 emissions — resulting from both land conversion and shrimp production — have not been included in Brazil’s emission statistics (2, 25), thereby underestimating the country’s share in the responsibility of climate change mitigation.
Salt flat conversions outlined in the BFC could lead to staggering mangrove losses and hugely increase CO2 emissions, considering that these systems possibly store an equivalent to roughly 2.5 times annual global carbon dioxide (CO2) emissions (26). Considering only shrimp farms that have already been installed in the country, these land conversions correspond to 1.5% of all Brazilian marine wetlands, or only 0.03% of the national territory; however, they alone account for 1% of the total Brazilian yearly CO2 emissions (2, 27).
Considering Brazil’s mangrove coverage, which makes it a critical player on the mitigation of the CO2 effects and climate change stabilization, we ask for international support to help in reversing this horrible political decision. Join us by exerting any type of pressure, either by divulgating this absurd decision or by writing straight to our government representatives (contact info attached).
Thank you very much.

Dear Honorable President Rousseff,
I wish to draw your attention to a dangerous revision to your country’s coastal regulations that are troubling me now. Recent amendments to Brazilian Forest Code (BFC) threaten your country’s mangrove forests and will, if implemented, adversely affect the status of Brazil as the second largest mangrove area in the world. Because of this ill-conceived amendment, I am very concerned for the future of all of Brazil’s coastal wetlands, including the mangroves and their associated inter-tidal wetland areas- the mud flats and salt flats, sea grass beds and coral reefs.
Assessments made prior to the consolidation of shrimp farming industry in Brazil revealed that the country had already lost 50,000 ha between the years of 1985 and 2000 due to diverse causes. Nevertheless, it is estimated that shrimp farming industry alone is responsible for the conversion of another 50,000 ha of the country’s tidal wetland ecosystems into ponds, mainly on salt flats, which will be the last refuge for the mangroves to colonize as the sea level rises as is now occurring at a much moré rapid rate than earlier predicted. Loss of these intertidal areas to expanding shrimp farm development will mean loss of future mangroves that would otherwise have colonized those same sites.
For the sake of combating climate change and restoring your country’s coastal wetlands and wild fisheries, I ask that you please reconsider this troubling amendment and act now to reverse this earlier decision.
For the Mangroves And the Mangrove Communities!
