Areas of land the size of European countries stand to have protections revoked for development
With the world’s largest system of protected areas and a 70 percent drop in the deforestation rate of the Amazon over the past decade, Brazil has made huge strides in safeguarding what’s left of its wilderness. However, this progress now hangs in the balance, with new laws threatening to turn many of the country’s protected areas into mines and dams.
A report released today in Science details the impacts of the legislation, which is currently under debate by the Brazilian Congress. One proposal is calling for 10 percent of the country’s most stringently protected areas (PAs) to be developed for mining, which would affect an area the size of Switzerland encompassing national parks, biological reserves, and wildlife refuges. Brazil’s indigenous-held land would be even more impacted, with 281,000 square kilometers —an area bigger than the UK—at risk of mining development. Proposed hydroelectric dams stand to disturb downstream PAs, limiting the movement of aquatic species and flooding out terrestrial ones.

The proposals include plans for mitigating and reducing environmental damage from development. However, the authors of the report caution these plans do not go far enough to address the scope of impact.
“Our concern is that even if the proposed mitigation actions were put in place they are oversimplified because they fail to take account of the indirect effects of mega-projects,” said coauthor Dr. Luiz Aragão. “These projects can involve thousands of workers and lead to rapid local population growth. This, combined with new roads and access routes, is a recipe for the emergence of new deforestation frontiers.”
Brazil boasts more than 12 percent of the world’s PAs, with 17.6 percent of its land granted federal, state, or municipal protection. However, since 2008, Brazil had already reduced safeguards for 44,100 square kilometers of PAs to facilitate development, calling into question the efficacy of such “protection.”
Brazil has had great success in reducing deforestation in the past decade, effectively sparing 86,000 square kilometers of rainforest from the chainsaw and thereby preserving wildlife habitat and preventing the release of 3.2 billion tons of carbon dioxide emissions, according to a study published in Science earlier this year. However, while forest loss has been stymied in the country, it definitely has not been stopped. The state of Pará, for example, lost nearly 8.1 hectares—more than 7 percent—of its forests from 2001 through 2012, according to data from Global Forest Watch. This, despite an abundance of protected areas occupying almost half the state’s land area.
While most of Pará’s forest loss occurred outside its PAs, deforestation happened within them in several places. For instance, Global Forest Watch shows the Triunfo do Xingu Environmental Protection Area in the middle of the state experienced more than 361,000 hectares of deforestation from 2001 through 2012.

In addition to threatening its own biodiversity and resources, the authors of the report worry Brazil’s PA reductions may have global repercussions.
“Beyond the conservation and stewardship of its own biodiversity and environmental resources, so vital to the wellbeing of its citizens, Brazil plays a vital role in motivating and supporting the adoption of more sustainable development trajectories around the world,” said coauthor Toby Gardner. “Yet this standing is now in jeopardy.”
The population of Brazil nearly quadrupled in 60 years, from 54 million in 1950 to 195 million in 2010. Balancing the needs of a growing human populace with those of the environment can be a tricky issue, one the authors of the report say Brazil’s government should address more thoughtfully.
“The purpose of this analysis is not to say that Brazil´s development should not benefit from its abundant natural resources,” said Dr. Joice Ferreira, lead author of the report, “but that we should not squander our hard-won record of success and leadership in favor of fast-tracked and poorly planned development projects that leave a long legacy of environmental damage.
“It is possible to manage our development in a more sustainable way.”

Is the world moving backwards on protected areas?
(11/06/2014) Protected areas are undoubtedly the world’s most important conservation success story. But, despite this, progress on protected areas is stalling and in some cases even falling behind. According to a sobering new paper, only 20-50 percent of the world’s land and marine protected areas are meeting their goals, while the rest are hampered by lack of funding, poor management, and government ambivalence.
91% of Kenya’s protected areas shrank in 100 years
(11/04/2014) Over the last century, 91.7 percent of all changes to protected areas in Kenya have involved reductions in their area, known as downsizing, which is an unusual and remarkable statistic from a global perspective. Analyses show, however, that a variety of factors—including some that which occurred half a century ago—could be responsible for the status of forests in Kenya today.
Russia and China blamed for blocking Antarctic marine reserve
(11/03/2014) Another year, another failed attempt to protect a significant chunk of the Ross Sea, which sits off the coast of Antarctica. According to observers, efforts to create the world’s biggest marine protected area to date were shot down by Russia and China during a meeting in Hobart, Tasmania of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
De-protection of Protected Areas ramps up in Brazil, ‘compromises the capacity’ of ecosystems
(10/31/2014) Brazil has reserved about 17.6 percent of its land (1.5 million square kilometers) to receive protection from unauthorized exploitation of resources. However, despite significant expansions in protected areas since the mid-2000s, the formation of Protected Areas has stagnated in the country since 2009, and many have had their protections completely revoked.

The Kiwirrkurra IPA, as the area is known, is billed as the largest protected expanse of arid land on Earth.

Recently, however, its protection status has been questioned, and global-scale analyses show Panna is far from alone among India’s many threatened Protected Areas.
