Brazil Scientists Fear Golden Mussel Threat to Amazon River

February 5, 2015

Jenny Barchfield – ABC News, 2/5/2015

The world’s mightiest waterway, the Amazon River, is threatened by the most diminutive of foes — a tiny mussel invading from China.

Since hitching its way to South America in the early 1990s, the golden mussel has claimed new territory at alarming speeds, plowing through indigenous flora and fauna as it has spread to waters in five countries. Now, scientists fear the invasive species could make a jump into the Amazon, threatening one of the world’s unique ecological systems.

“There’s no doubt the environmental effect would be dramatic,” said Marcia Divina de Olivieira, a scientist with the Brazilian government’s Embrapa research agency.

Brazil sees “surprising” deforestation drop in Amazon

November 27, 2014

BBC News, 11/26/2014

Brazil said deforestation in the Amazon rainforest has dropped by 18% in the past year. Environment Minister Izabella Teixeira said the fall, for the year ending July 2014, meant deforestation was at its second lowest level in 25 years.

But campaigners say alternative monitoring shows an increase for a second year running.

In 2012 the government eased restrictions on landowners, weakening legal protection for the rainforest. Ms Teixeira said 4,848 square kilometres (1,872 square miles) of rainforest were destroyed between August 2013 and July 2014. The figure was down from 5,891 kilometres (2,275 square miles) during the same period a year earlier.

Water War Amid Brazil Drought Leads to Fight Over Puddles

November 25, 2014

David Biller and Vanessa Dezem – Bloomberg, 11/25/2014

Brazil’s Jaguari reservoir has fallen to its lowest level ever, laying bare measurement posts that jut from exposed earth like a line of dominoes. The nation’s two biggest cities are fighting for what little water is left.

Sao Paulo state leaders want to tap Jaguari, which feeds Rio de Janeiro’s main source. Rio state officials say they shouldn’t suffer for others’ mismanagement. Supreme Court judges have summoned the parties to Brasilia for a mediation session this week.

The standoff in a nation with more water resources than any other country in the world portends further conflicts as the planet grows increasingly urban. One in three of the world’s 100 biggest cities is under water stress, according to The Nature Conservancy, a U.S.-based nonprofit.

FAPESP Countdown: “The many faces of the sertão”

November 13, 2014

The Brazil Institute is counting down to this year’s FAPESP Week (November 17-21), organized in collaboration with the São Paulo Research Foundation (FAPESP), UC Berkeley, and UC Davis. The symposium aims at strengthening the links between scientists from Brazil and the U.S. with the objective of promoting research partnerships.

During an 1818 Austrian expedition to Brazil—a scientific investigation that brought over researchers and artists to study and depict species and landscapes characteristic of Brazilian biodiversity—two naturalists, Carl Friedrich von Martius and Johann Baptiste von Spix, were struck by the diversity of vegetation in a forest that was theoretically rare for the region around the banks of the São Francisco River in what is now the municipality of Januária, in Minas Gerais State. Their fascination was largely justified by the fact that the vegetation was in an area that was part of the Caatinga, an ecosystem identified by a predominantly semi-arid climate and scarce, highly variable water availability. The two German naturalists probably thought, like many others, that the Caatinga is a homogeneous environment, but that is not the case.

“The region has a wide variety of environmental conditions that are essential to the emergence and sustenance of a number of species well adapted to the regional climate,” said biologist Bráulio Almeida Santos of the Federal University of Paraíba (UFPB), in a lecture he presented at the fifth BIOTA-FAPESP Education Conference Cycle, on June 20, 3013 in São Paulo.

The Caatinga, he explained, presently occupies 11% of Brazilian territory, an area approximately 845,000 square kilometers (km2) in size. It is divided into eight ecoregions—each having very distinct landscapes, soil types and vegetation—that can receive rainfall of less than 1,000 millimeters in a year’s time. “In some areas, a dry spell can last as long as 11 months,” he said. The region is currently experiencing its worst drought in 30 years, affecting the lives of 27 million people. In the state of Bahia alone, over 214 municipalities have declared a state of emergency this year.

FAPESP Countdown: “Green Flight”

November 7, 2014

The Brazil Institute is counting down to this year’s FAPESP Week (November 17-21), organized in collaboration with the São Paulo Research Foundation (FAPESP), UC Berkeley, and UC Davis.

Marcos de Oliveira – Pesquisa FAPESP, 2014 Print Edition, Published in July 2013

The accounting has been done. By 2050 commercial aviation is expected to reduce its emissions of carbon dioxide (CO2) by 50%, compared to the amount emitted by aircraft engines in 2005. In order to accomplish this, institutions and companies in a number of countries are carrying out a great deal of research and development to produce a non-petroleum based kerosene from renewable sources, one that will release fewer harmful gases into the atmosphere. Biokerosene, as it is being called, is likely to once again make Brazil a major world reference center for the development and production of a biofuel, as it was with ethanol and biodiesel.

This trend is highlighted in the study “Flightpath to Aviation Biofuels in Brazil: Action Plan” presented in early June in São Paulo, and sponsored by two of the three largest aircraft manufacturers in the world, Boeing and Embraer, with FAPESP funding and coordinated by the State University of Campinas (Unicamp), Interdisciplinary Center for Energy Planning (NIPE). Also participating in the study, developed over the course of one year with the completion of 8 workshops, were 33 partners, including national and international companies, universities and research institutes.

The study presents several technological routes that begin with raw materials such as traditional sugarcane, algae, animal fats, vegetable oils, lignocellulosic material, starches and urban waste, and use different conversion and refining technologies to obtain biokerosene. At this stage, the study also concludes that there are still many significant gaps to be closed when it comes to technology and costs. Technical difficulties will require the participation of all those involved, aircraft manufacturers and aviation companies, developers and suppliers of fuel, in addition to the world’s certifying bodies. Another factor to be taken into consideration is the logistics of producing and distributing biofuels to 108 domestic airports where large aircraft operate, representing 1 million scheduled flights just in Brazilian airspace, and the need to service 62,000 international flights departing each year in Brazil, bound for 58 airports in 35 countries. These outgoing flights represent 60% of the kerosene consumed by aviation in Brazil.

Brazil Says No to Anti-Deforestation Plans: The Difficulty of a Global Response to Climate Change

September 23, 2014

Hannah Osborne – International Business Times, 09/23/2014

Brazil has refused to endorse a global anti-deforestation initiative put forward at the UN climate summit because it says it was left out of the consultation process.

According to an exclusive report by the Associated Press, environment minister Izabella Teixeira said her country was “not invited to be engaged in the preparation process” of the plan.

“Unfortunately, we were not consulted. But I think that it’s impossible to think that you can have a global forest initiative without Brazil on board. It doesn’t make sense,” she said. However, a UN official denied her claims, saying “there were efforts to reach out to the Brazilian government”. Charles McNeill, a senior environmental policy adviser with the UN, said: “There wasn’t a response [from Brazil].”

Brazil’s Silva, a lifelong environmentalist, courts big agriculture

September 15, 2014

Reese Ewing – Reuters, 09/13/2014

Brazilian presidential candidate Marina Silva, an icon of the green movement, is cozying up to old adversaries in the sugar and ethanol industry as she seeks to win over the powerful farm lobby ahead of next month’s election.

Since entering the race in mid-August, Silva has picked a pro-agriculture congressman as her running mate, met repeatedly with agribusiness leaders and campaigned in the farm belt, eager to make allies in an industry that accounts for a quarter of Brazil’s economy.

Her message: conservation and big agriculture would thrive side-by-side in a Silva government and she would roll back the gasoline subsidies that President Dilma Rousseff has used to contain inflation. The fuel price controls have gutted Brazil’s once-booming sugar cane ethanol industry.
