Here the coast is dominated by extensive sand dunes, interspersed with pockets of mangroves in bays and river mouths. In this type of false colour composite images, mangrove appears in different shades of red.
As organizations collect more and more data, the ability to map, visualize and understand data form a geographic standpoint will become an increasingly important part of any BI solution. Why? Because, according to IDC, more than 80 percent of the data collected by organizations has a spatial element.
The Mamore River drains north from the Andes Mts. in lowland Bolivia. An image taken in July 2003 from the International Space Station (ISS007-E-10797, 14 June 2003, 12:36 GMT) shows an 85 km stretch of the river south of the lowland town of Trinidad in the Beni Province. A 55-km stretch (centered at 15.2°S 66°W) was rectified to the commercially available 1990 edition of the Landsat TM imagery of the world.
Numerous changes in river pattern are visible in the decade since the Landsat imagery was acquired. A pilot study was undertaken to characterize these rapid changes. Tie points were selected for geomorphic features which do not undergo short-term change- i. e. oxbow lakes and subsidence lakes in the floodplain. The ISS image was enhanced slightly to reveal the Mamore River channel......
Two new reports reveal the dangers of global warming-induced sea level rise. The report is rounded out by an interactive map, which may be the most interesting news to come out of the effort (we've known for quite some time, after all, that folks who live in coastal areas near sea level are in trouble). The tool lets users zoom around and see exactly how rising sea levels are projected to impact their communities at different points in the future.
As we've noted in this series, scientists are concerned that global warming could cause much of the world's permafrost (deep-frozen soils) to thaw, releasing vast quantities of greenhouse gases that would accelerate climate change – an example of a positive feedback loop.
Measurements have shown that southerly permafrost regions have already started to thaw and some additional thawing is unavoidable. Even if all man-made emissions ceased today, an additional global warming of about 0.6C would be expected due to the inertia of the climate system. Furthermore, due to polar amplification, man-made warming affects permafrost regions disproportionately: they warm around 50% more than the globe as a whole.......
Agência FAPESP – The city of São Paulo has undergone intense change in recent decades, radically transforming its social and spatial characteristics and making the urban fabric much more heterogeneous and complex.
This false colour composite scheme allows vegetation to be detected readily in the image. In this type of false colour composite images, vegetation appears in different shades of red depending on the types and conditions of the vegetation.
Saving biodiversity -- the vast and essential variety of the natural world -- will be expensive, at an estimated $300 billion a year for the next eight years.
WASHINGTON (Reuters) - Saving biodiversity -- the vast and essential variety of the natural world -- will be expensive, at an estimated $300 billion a year for the next eight years. But losing it would cost even more, in terms of disease, hunger, poverty and diminished resilience to climate change, according to the new chief of the U.N. Convention on Biological Diversity.
"Biodiversity is the basis of everythingwe do in agriculture, everything we do in health," Braulio Ferreira de Souza Dias told Reuters.
"So the development of new vaccines, the development of new cultured varieties of plants is based on biodiversity, genetic resources. If we lose biodiversity, we lose the options for future development in these areas."
Human destruction of natural habitats, unbridled economic development, pollution and climate change are among the threats to plant and animal life, on land and underwater. Preserving biological diversity is an uphill fight as the needs of the world's growing human population - now numbering about 7 billion - increasingly come into conflict with protecting nature.
Dias, named to the job in January, starts from a position of certainty: 192 nations already have agreed on what needs to be done by 2020 to preserve biodiversity.
His job is to help them figure out how to do it. He will have the chance to do that when global representatives gather in Rio de Janeiro in June, 20 years after the first Earth Summit set out a plan for worldwide environmental protections.
This year, the meetings will focus on sustainable development, a theme purposely chosen to avoid climate change controversies. It is an important one for Dias, who previously headed biodiversity for the Brazilian ministry.
Dias has been impressed by some of the biodiversity pilot programs launched by companies and governments around the world, but he believes these efforts need to be quickly expanded.
A Embrapa vai realizar o mapeamento de toda a agricultura brasileira por imagens de satélite. Em 2012, os investimentos em geotecnologias aplicadas ao monitoramento da agricultura e em inovações em agroenergia são as prioridades.
Training your brain to be positive is not so different from training your muscles at the gym. Recent research on neuroplasticity—the ability of the brain to change even in adulthood—reveals that as you develop new habits, you rewire the brain.
