DETER registra em agosto 756 km2 de desmatamento na Amazônia ( INPE )

29/09/2008

O sistema DETER – Detecção do Desmatamento em Tempo Real, do Instituto Nacional de Pesquisas Espaciais (INPE), conforme descrito na página de entrada do projeto (www.obt.inpe.br/deter/), é uma ferramenta para suporte à fiscalização e não uma avaliação fiel do desmatamento mensal da Amazônia, em função da resolução dos satélites e da cobertura de nuvens variável de um mês para outro. A informação sobre áreas é para priorização por parte das entidades responsáveis pela fiscalização. O DETER deve ser usado apenas como indicador de tendências do desmatamento anual.

O sistema DETER apontou em agosto 756 km2 de desmatamento na Amazônia Legal. Deste total, 435 km2 no Pará e 229 km2 no Mato Grosso. É mais que o dobro de julho, quando o desmate ficou em 323 km2. Mas o número é menor que o registrado nos meses de junho, maio e abril, este o pior de 2008 segundo o DETER, quando a Amazônia perdeu em 30 dias 1.124 km2.

Estes números, que consideram áreas que sofreram corte raso (desmate completo) ou degradação progressiva, devem ser analisados em conjunto com os dados sobre a ocorrência de nuvens, que impedem o monitoramento por satélite.

Em agosto, 74% da Amazônia Legal pôde ser vista, porém ficaram encobertos 99% do Amapá e 77% de Roraima. O Mato Grosso ficou livre das nuvens em agosto, enquanto o Pará teve 24% de sua área encoberta. Esta cobertura é para o conjunto de imagens MODIS que foram utilizadas.

A tabela abaixo mostra a distribuição dos 756 km2 por Estado.

Acesse aqui o relatório com os mapas que indicam as áreas com nuvens, gráficos e tabelas com os números do desmatamento registrados pelo DETER no mês de agosto.

Avaliação
Com imagens dos satélites Landsat e CBERS, que apresentam melhor resolução espacial (20 e 30 metros), o INPE faz a qualificação dos dados do DETER, que usa sensores cuja baixa resolução (250 metros) é compensada pela capacidade de observação diária. O Relatório de Avaliação, disponível no site www.obt.inpe.br/deter, mostra que 89% das áreas apontadas pelo DETER foram confirmadas como desmatamento. Foram avaliados 420 Alertas, que representam 446 km2 ou 59% da área total dos polígonos (756 km2) indicados pelo DETER no mês de agosto.

Os Alertas indicaram principalmente desmatamentos por corte raso (67,5%) e por degradação florestal de intensidade alta (17%), categorias em que a resposta do solo é predominante sobre a cobertura florestal escassa. O sistema DETER foi preciso principalmente na detecção de polígonos maiores que 1 km2.

Os polígonos não confirmados como desmatamento (11%) eram na maioria menores que 2 km2. Para os técnicos do INPE, estes resultados comprovam que os Alertas do DETER são eficientes para orientar a fiscalização e indicar as áreas prioritárias para a vistoria de campo.

O DETER
Em operação desde 2004, o DETER foi concebido pelo INPE como um sistema de alerta para suporte à fiscalização e controle de desmatamento. São mapeadas tanto áreas de corte raso quanto áreas em processo de desmatamento por degradação florestal. É possível detectar apenas polígonos de desmatamento com área maior que 25 hectares por conta da resolução dos sensores espaciais (o DETER utiliza dados do sensor MODIS do satélite Terra e do sensor WFI do satélite sino-brasileiro CBERS, com resolução espacial de 250 metros). Devido à cobertura de nuvens, nem todos os desmatamentos maiores que 25 hectares são identificados pelo sistema.

Efficient monitoring system guarantees donation to the Amazon Funds

Sep 17, 2008

“The sophistication of the Brazilian monitoring system from Amazon Forest deforestation, convinced the Norwegian government to donate up to US$ 1billion from 2008 to 2015 periods, in the Amazon funds – destined to protect the biggest forest coverage from the continent” said on this Wednesday (Sept 17th) the newspaper Valor Econômico. This news regarding the donation from Norwegian part mainly due to the forest satellite monitoring system, which was developed and operated by the National Institute for Space Research (INPE), was also mentioned in newspapers like O Estado de São Paulo.

The donation was formalized on Tuesday, 16th, at Palácio do Planalto, by Jens Stoltenber, Norway First Minister. The initial grant was US$ 20 billions and for the next 12 months is also guaranteed more US$ 120 millions to the Fund which was created just for the purpose of capturing resources in the international and national market and for applying them to the sustainable developing programs, technological innovation researches as for the conservation of biodiversity from the region.

Satellite Surveillance

Based on satellite images, the monitoring of Amazon deforestation accomplished by INPE is internationally recognized by its excellence and pioneering. PRODES, with 20 years of history, is considered the biggest forest tracking program of the world, for covering a forested area of 4 billion km2 with annual frequency. This result has been showing both the medium average and the Brazilian Amazon deforestation extension estimative - as well as has been guiding the region public policies.

Since 2004, INPE also has been operating DETER ‘system – Deforestation Detection in Real Time, which uses high frequency surveillance sensors for providing quickly data to the environmental management departments, keeping this way under control the deforestation process.

Another important tool used in the preservation of the Planet biggest natural reserve is the orbital heating focus monitoring, which provides information for the Prevention Program and Control to the Forest Fire and burning in the Deforestation Arch, known as PROARCO, under IBAMA responsibility.

Brazilian government faces criminal charges over Amazon deforestation

Illegal logging increases sharply as rising food prices push soy farmers and cattle ranchers to clear more land

The Brazilian government faces criminal charges after a report found that the Amazon rainforest is being deforested three times faster than last year as rising food prices encourages more illegal logging.

A study by Brazil’s National Institute for Space Research found that destruction of the Amazon had increased 228% in August compared with the same month a year ago.

Carlos Minc, the Brazilian environment minister, said the upcoming national elections were partly to blame, with mayors in the Amazon region ignoring illegal loggers in the hope of gaining votes locally.

Environmental campaigners blamed the global spike in food prices for pushing soy farmers and cattle ranchers to clear more land for crops and grazing.

“The tendency of deforestation rising is deeply related to the fact that food prices are going up,” said Paulo Adario, who coordinates Greenpeace’s Amazon campaign. “When you have elections, the appetite of authorities to enforce laws is reduced. But the federal government has to step in and do its job.”

The steep rise in deforestation is a sharp reversal after three years of decline in the rate of destruction.

Official data showed that some 300 square miles (756 square kilometres) were chopped down last month, twice the rate of July.

The minister released a list of the 100 worst individuals or companies responsible for most of the deforestation since 2005.

The Brazilian government’s land and agrarian reform agency, Incra, was accused of being the worst.

Minc said the environment ministry will bring criminal charges against all of them. The government will also create an environmental police force with 3,000 heavily armed and specially trained officers to help combat illegal deforestion.

The institute, which uses satellite imagery to track down illegal logging, said the destruction was likely to be worse than figures show since no information was available for 26% of the Amazon because of cloud cover in August.

Greenpeace has accused Incra officials of illegally handing over rainforest to logging companies and creating fake settlements to skirt environmental regulations.

Minc said Incra was responsible for destroying 220,150 hectares (544,000 acres) of the world’s largest rainforest in the past three years.

The news that Incra topped the list of violators is likely to fuel the argument of large landowners that poor peasants are to blame for the destruction of the Amazon. One of Incra’s duties is to distribute land to the poor.

There was no immediate comment from Incra.

Most of the remainder of Minc’s list comprises Brazilian farmers and ranchers.

Un informe de la Agencia Europea de Medio Ambiente afirma que el país vivirá sus próximos años entre inundaciones y sequías

MARUXA RUIZ DEL ÁRBOL - Madrid - 29/09/2008

El estrés del agua quiere decir sequía y desertificación. Significa que en el futuro, a nuestra lista de preocupaciones, se añadirá la falta de agua. Pero también el exceso: inundaciones y crecidas de ríos. Es la expresión que utiliza la Agencia Europea de Medio Ambiente (EEA) para calificar lo que va a sufrir en las próximas décadas España y todos los países de la cuenca del Mediterráneo.

Las lluvias serán muy intermitentes en Europa y lloverá poco

Para mitigar los problemas se apuesta por la reducción del CO2

La falta de agua tendrá un efecto negativo en términos económicos

El 90% de los desastres europeos desde 1980 guarda relación con el clima

La Unión Europea ha publicado un informe llamado Impactos del cambio climático en Europa que especifica las convulsiones que vivirá el viejo continente por el calentamiento global. El estudio analiza la cantidad del agua que el hombre ha necesitado entre 1975 y 2006 y, por otro lado, muestra la evidencia de que las lluvias serán muy intermitentes en Europa. Lloverá poco y se necesitará más agua. “En el mismo período ha habido un significativo incremento en la demanda de agua en España (entre el 50% y el 70%) y en las áreas mediterráneas”, asevera el informe. Y las predicciones de futuro van en línea ascendente. “La demanda crecerá cada vez más, especialmente en el sur donde la necesidad de agua para la agricultura es mayor. Con ella, se desarrollará una competición por este bien entre los distintos sectores (turismo, agricultura, energía) y usos”.

En promedio, la exigencia de agua en todos los países de Europa ha crecido al rededor de 50 milímetros cúbicos por hectárea al año pero, en algunos casos como en el centro de España, Italia, Grecia, el Magreb, el sur de Francia y Alemania la cifra oscila entre 150 y 200 metros cúbicos por hectárea al año. Y, como se prevé que las lluvias, se reducirán se necesitará regar más. Por eso la falta de agua causará un impacto negativo tanto en términos económicos como en ecológicos. Además, en el Mediterráneo se ha observado un creciente déficit del agua en los últimos 32 años.

Aunque el informe vaticina desertización para España, el estudio tampoco nos libra de los desbordamientos de los ríos. Habrá un incremento porque la alternancia entre períodos de sequía y precipitaciones torrenciales hace a España más propensa a estas inundaciones. Para 2080 pronostica que entre 2000 y 4000 personas se verán afectadas por las inundaciones en las zonas costeras por la subida del nivel del mar en Andalucía, Galicia, las Islas Baleares y Asturias. La región más afectada será el País Vasco: entre 4000 y 8000 personas podrán ser víctimas de la subida del mar. Países como Reino Unido, Sicilia o Grecia podrán ver afectada a gran parte de su población (entre 8000 y 50.000 personas). El planeta ya está experimentando una subida de las temperaturas de 0,8 grados centígrados por encima de los niveles preindustriales y el nivel del mar ha crecido 3,1 milímetros al año en los últimos 15 años.

Para mitigar todos estos problemas el informe apuesta tanto por la reducción del CO2 como por la adaptación a las consecuencias del cambio que ya no se pueden remediar. “El 90% de todos los desastres que han sucedido en Europa desde 1980 están directa o indirectamente relacionados con el clima y representan el 95% de las pérdidas económicas causadas por catástrofes”, señala el informe.

Para evitar estas pérdidas se pone tres metas: la primera, una mayor vigilancia, monitorización y estudio de los cambios a nivel internacional; la segunda, estabilizar el clima para 2020 por debajo de los dos grados centígrados con respecto a los niveles pre industriales “para evitar consecuencias irreversibles en la sociedad y en los ecosistemas”. Por último, hace hincapié en la adaptación.

Afirma que uno de los grandes retos de España de todo el Mediterráneo en adaptación es la diversificación del turismo en otros sectores. El estudio asegura que la subida de la temperatura hará marcharse a los turistas más al norte, en busca del mismo clima que antes se gozaba en España. Por eso, para no perder dinero, será imprescindible invertir en otros sectores.

As commodity prices soar, South America’s agricultural giant steps up to feed a needy world.

When I was a kid, in 1974, I moved with my parents to Brasilia, the brand new capital of Brazil, built in the middle of nowhere, at the hartland of the Cerrados in 1960. I remember how impressed I was, being a kid, seen so many empty spaces and nothing for kilometers and kilometers. My dad made our moving trip driving from Rio de Janeiro, it was 1,100KM ( 690 miles) trip trough a empties plains lands.

Today Brasilia has 2.0 Million inhabitants, the cerrado are very productive feeding the Brazilian population and sending food all around the world. That was a quite transformation that I could be a eye witness.

I have reported about that transformation before here .

Out here on this seemingly endless tropical savanna, it looks like more bumper crops are rising out of the ruddy earth. Verdant rows of corn and cotton stretch out toward the horizon—this just months after a record harvest of soybeans was cut from the same tracts.

Given the abundance here in the fields, it’s hard to believe that these plains were once dismissed as sterile wastelands best left to the emus, armadillos, monkeys, anacondas, and the odd jaguar. The acidic soil was thought to rule out significant farming.

The Brazilians still call these lightly wooded plains the cerrado—or “closed” or “inaccessible” land. But nowadays the cerrado is very much open for business, its fertility a springboard from which the world’s newest superpower in agriculture is emerging. “We have been able to transform wasteland into a bountiful land that is helping to feed Brazil and the world,” says Silvio Crestana, head of the Brazilian government’s agricultural research company, EMBRAPA.

With millions of people literally hungering for affordable food, Brazil’s breakthroughs in tropical agriculture may prove to be the key to feeding a growing global population. If Saudi Arabia fills the world’s gas stations, China assembles its consumer goods, and India vies to staff its office services, then it is Brazil that is stepping forward to stock its pantries. The rise of Brazil as an agricultural powerhouse may be the most important story of globalization that many Americans have never heard of.

With ample sun and fresh water and more available arable land than any other country, Brazil seems to be on a historic trajectory to becoming the next great global breadbasket. “Brazil can be No. 1 in the future in agricultural production,” asserts André Nassar, a leading agricultural economist based in São Paulo. “I think we will exceed the U.S.”

If that ambition pans out, Brazil may provide the supply cushion the world urgently needs to meet growing demands for food. China, India, Russia, and other countries are eating higher on the food chain; they want more of the grains and meat Brazil can provide. The same soaring commodity prices that have inflicted so much global pain are creating wealth in Brazil’s fast-growing hinterlands. “The crisis is not bad for Brazil. It allows farmers to get a better price,” says Derli Dossa, a strategic adviser in the Ministry of

Brazil’s farms see quiet revolution

By Gary Duffy
BBC News, Sao Paulo

On the family farm run by Joao Baggio Neto in the southern Brazilian state of Parana, you get some sense of the determination and competitive spirit that motivates Brazil’s farmers.

Brazil has become a global food superpower by stealth

Blessed with what often seems like endless amounts of land and a good climate, Brazil has grown in recent years to become an agricultural superpower.

Joao Baggio says the most important improvement in his part of the country in the past decade has been the increase in productivity.

“We came from a situation where we produced 5,000 kg of corn by hectare, while today it is 10 to 12,000 kg per hectare of corn,” he says. “So we have doubled productivity in 10 years.”

So it is no surprise that the government launched its latest agricultural plan in the state of Parana, famous for its grain-producing potential.

President Luiz Inacio Lula da Silva told farmers that concerns about food prices and shortages around the world offered them an exceptional opportunity.

“We have more Chinese people eating, we have more Indians eating, we have more Africans eating and we have a lot more Brazilians eating.

“All this, which is treated by the press as if it were a crisis and is sold to the world as if it were a crisis,” he said.

“Without any arrogance or self-importance, we Brazilians need to confront what for others is a crisis, as an extraordinary opportunity to truly transform ourselves into the granary of the world, as many people have long predicted.”

Huge potential

Joao Baggio is not a fan of government policy, but he does not disagree with the president’s aspiration.

“Without any doubt, there is potential to produce if the government doesn’t get in the way,” he says.

“We are not even going to say help - if they don’t get in the way a lot, year by year the producer is generally increasing production.

“If you talk about central Brazil, there are still a lot of areas to be exploited, so I don’t have much doubt.”

In fact, of the 350 million hectares of land available for agriculture across Brazil, analysts say only 70 to 80 million hectares are being used, and the potential for growth is enormous.

But there is also a consensus that the country has to deal with some key weaknesses, such as poor infrastructure - mainly in its ports and roads - and a high level of dependence on expensive imported fertilisers.

But for Professor Marcos Fava Neves of the University of Sao Paulo, the president is right to think on a grand scale, based on the country’s recent achievements.

“What we have seen in the last 10 years is a quiet revolution happening in our country, mostly in agribusiness production,” he says.

“We came from being an irrelevant international market participant to be one of the world’s major food and biofuel suppliers today.

“So if you look at what happened to our agriculture in terms of beef exports, poultry exports - again we were irrelevant, and now we have the position of largest exporter in the world in major food crops.”

Booming harvests

It is no surprise, then, that there was a confident opening for the annual gathering of Brazil’s major agricultural producers in Sao Paulo.

The video presentation boasted of a record harvest - while the prediction for this year is that external sales of agricultural products could amount to $74bn, an increase of 26% on last year.

The only threat to Brazil’s abundance is global warming

Outside the conference hall, the main point of discussion was a new report suggesting climate change could cause a significant drop in Brazil’s food exports - perhaps as much as a quarter for soya over the next 12 years.

However, Agriculture Minister Reinhold Stephanes was adamant this concern over climate change could be addressed.

“The impact will start to emerge with more intensity within 20 to 30 years, and until then, we should be preparing for this,” he said.

“The perspective for the moment for future harvests is highly productive. So Brazil has the potential to continue growing around 5% to 6% a year in terms of increasing harvests. We are going to effectively maintain this rhythm in the coming years without any problem.”

Brazil’s major producers also insist they can achieve growth in a sustainable way, even though activities such as cattle-ranching have been widely blamed for deforestation in the Amazon.

Investment drive

Watching the conference proceedings was Paulo Adario, campaigns director for Greenpeace, who says Brazil must meet its ambitions while protecting the environment at the same time.

“Greenpeace is not against food,” he told the BBC. “We are not against expanding the Brazilian capacity for producing food, and helping Brazil to develop this country.

“You can increase the food capacity through technology, through better practices, through occupying areas that are already degraded, to investing in better crops.

“But you can not increase your productivity at the expense of the environment, because the global market doesn’t accept this price any more.”

Prof Neves says even by staying away from sensitive areas such as the Amazon, a huge amount can be achieved.

“If we have the right investments coming on for logistics, for infrastructure and for technology and land development, the country can multiply by two-and-a-half, three times the actual production in the next 10 years.”

Prof Neves sees Brazil as being well placed to help bring worldwide food inflation down by increasing its productivity.

“Of course we have increases that could come from Europe, from the USA, from Canada, from Argentina,” he says.

“But where you see the best conditions in order to give the world society the best rate of return in terms of investment is in Brazil.

“If you talk about the next five years, we are now producing 130 million tonnes of grains. We can easily go to 250 million tonnes.

“We are now producing seven million hectares of sugar cane. This can go to 20 million hectares, helping to supply ethanol to the world. We are only exporting $400m of fruits; we can go to $3bn of fruits.”

Rising demand

It is not only in Brazil that Prof Neves sees potential.

“Next up is Africa. I think for Africa, this could be a redemption, in terms of inclusion of people in production systems and making Africa produce food and biofuels for the world.”

Not so long ago, the Brazilian government’s major social policy was the battle to ensure Zero Hunger among its own people. Yet now, its president says his country can be the food basket of the world.

A major family income support programme reaching 11 million of Brazil’s least well off families undoubtedly helped, but recent research suggests rising prices are affecting some important basic food products.

Prof Neves says Brazil’s exports can help feed the world

In one city in the north-east of the country, Brazil’s poorest region, an officially-monitored basic selection of food items has gone up by 50% over the last 12 months.

And given the scale of demand across the world, critics point out it is too much to expect Brazil to become its granary.

“World demand for food today is one billion tonnes, and Brazil produces 150 million tonnes,” columnist Ariosto Teixeira of the Estado de Sao Paulo newspaper told Brazil’s TV Globo.

“Brazil produces 150 million tonnes and the plan launched by the government for more food will produce six million more, which is going to leave one million for export. How is Brazil going to be the granary of food production?” he asked.

Despite this, Brazil undoubtedly exudes the sense of a country growing in confidence over its place as an agricultural producer, even allowing for the latest failure to reach agreement in world trade talks.

And along with other developing countries, the government remains optimistic that when it comes to the world’s concerns over food, Brazil can make a difference.
