C)Monitoring worlds forests By the time we find out about deforestation, it’s usually too late to take action.Scientists have been studying forests for centuries, chronicling the vital importance of these ecosystems for human society. But most of us still lack timely and reliable information about where, when, and why forests are disappearing.

This is about to change with the launch of Global Forest Watch an online forest monitoring system created by the World Resources Institute. Google and a group of more than 40 partners. Global Forest Watch uses technologies including. Google Earth Engine and Google Maps Engine to map the world’s forests with satellite imagery. Detect changes in forest cover in near-real-time, and make this information freely available to anyone with Internet access.

By accessing the most current and reliable information, everyone can learn what’s happening in forests around the world. Now that we have the ability to peer into forests, a number of telling stories are beginning to emerge.

Global forest loss far exceeds forest gain

Legend: Red = tree cover loss • Blue= Tree cover gain

According to data from the University of Maryland and Google. The world lost more than 500 million acres of forest between 2000 and 2012. That’s the equivalent of losing 50 soccer fields’ worth of forests every minute of every day for the past 13 years! By contrast. Only 0.8 million km2 have regrown, been planted. Or restored during the same period.

The United States’ most heavily forested region is made up of production forests

Legend: Pink = tree cover loss • Blue= Tree cover gain

The Southern United States is home to the nation’s most heavily forested region. Making up 29 percent of the total U.S. forest land. Interestingly, the majority of this region is “production forests.” The mosaic of loss (pink) and gain (blue) in the above map shows how forests throughout this region are used as crops grown and harvested in five-year cycles to produce timber or wood pulp for paper production. F)Monitoring worlds forests

This practice of “intensive forestry” is used all over the world to provide valuable commodities. And bolster regional. And national economies. WRI analysissuggests that if managers of production forests embrace a “multiple ecosystem services strategy”. They will be able to generate additional benefits such as biodiversity. Carbon storage. And water filtration.

Forests are protected in Brazil’s indigenous territories

Legend: Pink = tree cover loss • Dark green= forest • Light green = Degraded land or pastures

The traditional territory of Brazil’s Surui tribe is an island of green surrounded by lands that have been significantly degraded and deforested over the past 10+ years. Indigenous communities often rely on forests for their livelihoods and cultural heritage and therefore have a strong incentive to manage forests sustainably. However, many indigenous communities struggle to protect their lands against encroachment by illegal loggers. Which may be seen in Global Forest Watch using annual data from the University of Maryland and Google, or monthly alerts from Imazon. A Brazilian NGO and GFW partner. G)Monitoring worlds forests

Make Your Own Forest Map

Previously, the data required to make these maps was difficult to obtain and interpret, and most people lacked the resources necessary to access, view, and analyze the the information. With Global Forest Watch, this data is now open to anyone with Internet access. We encourage you to visit Global Forest Watch andmake your own forest map. There are many stories to tell about what is happening to forests around the world—and your stories can lead to action to protect these special and threatened places. What story will you tell? monitoring worlds forests

C)We’re excited to announce today that, in a collaboration led by Dr. Matthew Hansen at the University of Maryland, we’ve built the first detailed maps of the world’s forests, from 2000-2012. Documenting and quantifying forest landscape changes such as fires, tornadoes, disease and logging.The most significant findings were that the overall rate of tropical deforestation is increasing. And global forests have experienced a net loss of 1.5M sq km during 2000-2012 due to both natural (disturbance) and human causes.

Sumatra has lost over 50% of its natural forest within the past 30 years. Click to enlarge.

E)The detailed study was published today in the journalScience, High-Resolution Global Maps of 21st-Century Forest Cover Change. Key to the study’s success was the collaboration between scientists at the University of Maryland, who developed the models to analyze Landsat satellite data, and computer scientists at Google. Who then used Google Earth Engine technology to run these models on more than 650,000 Landsat images. While the analysis would have taken a single computer more than 15 years to perform.

Here are some other notable sites:

F)Paraguay’s Chaco woodlands within the western half of the country are experiencing rapid deforestation in the development of cattle ranches. The result is the highest rate of deforestation in the world. Click to enlarge. Mapping deforestation.

G)The Siberian larch forests of Yakutia, Russia, are prone to fire during spring to early summer. Such extensive fires result in significant carbon emissions. Click to enlarge. H)Mapping deforestation.

C)Forests are the mighty lungs of our planet. They absorb carbon dioxide, and emit oxygen on which all people and animals on Earth rely. For the sake of our future, it is critical that all people including the next generation, understand our global forests in order to manage them sustainably. Today, Science in the Classroom,Dr. Matt Hansen of the University of Maryland, and Google Earth Engine are presenting Global Forest.  Change Explorer to help engage young people in forest conservation.                              Change Explorer website contains maps that are available for interactive analysis as well as an accompanying activity worksheet.
