"Boto-cor-de-rosa", pink dolphin
Inia geoffrensis, commonly known as the Amazon river dolphin, is a freshwater river dolphin endemic to many rivers in Amazon (Photo from unknown source); which is at risk of extinction by its use as bait.A recent study published in the scientific journal Conservation Biology points out that between the years of 1981 and 2012, 93 amendments have been implemented in Conservation Units (UCs) of 16 Brazilian States, most of them resulted in the reduction of these areas.
Conducted by three Brazilian scholars, the study used a methodology of WWF, the PADDD, which categorizes these changes in total extinction of UC, size reduction and reduction in the level of protection. Within the 93 changes found are those which resulted in the loss of legal protection of 5.2 million hectares (= 52,000 km2), an area larger than the State of Rio de Janeiro.
Researcher of the Institute of man and the Environment (Imazon) Elis Araújo, co-author of the study, says these reduction data reflect a change in policy of protected areas in Brazil. "As of 2008, these changes have become more frequent, which 74 of them occurred between 2008 and 2012," comments.
Between the years 2010 to 2012, a total of 19 conservation units suffered limit reduction or protection by enterprises of generation or transmission of energy. "The weakening of protection of forest areas undermines their ability to deliver a number of benefits to society," said the researcher.
The study highlights the environmental services provided by Ucs and its economic potential. It is estimated that the creation and maintenance of Ucs in Brazil capture at least 2.8 billion tons of carbon annually, helping to reduce the greenhouse effect, as well as the potential to accommodate 20 million visitors per year with the possibility to generate an economic impact of approximately $ 1.1 billion.
