The world lost nearly 13 million hectares of forest – an area roughly the size of England – every year between 2000 and 2010. Agriculture and logging were responsible for most of that loss and degradation, which in turn led to higher greenhouse gas (GHG) emissions, regional haze, water pollution and a decline in biodiversity. The lack of timely, reliable, decision-ready data on what is happening in forests, and where, and who was doing it, makes it difficult to prevent further widespread deforestation.
In 2011, WRI began building a network that has grown to 50 organizations to create a publicly accessible, user-friendly online tool to provide accurate, up-to-date data on the status of the world’s forests.
GFW’s launch event in February 2014 offered a window on tree cover loss and gain, and provided national statistics, tree cover loss alerts and vast amounts of other information. By July, two new applications were also available: GFW Commodities, which showed the impact of suppliers of palm oil and other commodities on forests, and GFW Fires, which monitors and analyzes fires across Southeast Asia.
While WRI led this work, the mobilization of a path-breaking partnership was central to its success. Partners include the University of Maryland, Google, Esri, the Center for Global Development, Imazon, GFW Canada, ScanEx, Transparent World, the Jane Goodall Institute, CartoDB, Vizzuality, and Blueraster, with major funding from Norway’s International Climate and Forest Initiative, USAID, the GEF, DFID, the Tilia Fund, the Ministry of Foreign Affairs of the Netherlands, Sida, the Bobolink Foundation, and Danida.
GFW has catalyzed a dramatic increase in action against unsustainable and illegal forest practices. Governments and businesses are using GFW to improve forest management transparency and accountability. The Roundtable for Sustainable Palm Oil has used GFW to help members disclose where palm oil companies operate. Indonesia, a core partner, uses GFW Fire’s ultra-high resolution images to crack down on illegal burning. GFW has received worldwide attention, with more than 450,000 unique visitors, more than 1,200 media stories, and countless interactions via social media.
O Brasil possui maior quantidade de água doce do que qualquer outro país no mundo—12% do volume total de todo planeta. Então, como São Paulo—a maior e mais rica cidade da América do Sul—está ficando sem água? Três mapas ajudam a contar essa complexa história.
The rainforests of Africa’s Congo Basin are the world’s second largest, and are increasingly one of the most threatened. Agriculture, mining, logging, and climate change are already chipping away and thinning out the forests’ edge and interior. The Congo Basin forests’ biggest threat, however, is unseen: a lack of good information. With poor infrastructure, government capacity challenges, and hard-to-detect patterns of change, the forests of the Congo Basin are among the most difficult in the world to monitor and manage.
The UN has announced that March 21 be recognized as the International Day of Forests. In tandem with the celebration of forests worldwide, is an awareness that we are still losing forests and trees much faster than they can regrow.
Many people are working to reverse tree cover loss in the world’s largest remaining forests. But several hugely important deforestation hotspots are still flying under the radar. These forest areas are seeing alarming trends and/or have lost much of their tree cover. We are using the latest data from Global Forest Watch, an online forest monitoring and alert system, to dive deeper into some under-reported deforestation hotspots.
Kebakaran terakhir di Indonesia kemungkinan besar berakar dari pembukaan lahan untuk pertanian, perkebunan, dan produksi kayu. Menurut data dari [Global Forest Watch] (http://www.globalforestwatch.org/)-sistem online baru yang melacak perubahan tutupan pohon, dan informasi lainnya secara nyaris seketika ** setengah dari peringatan titik api terjadi di lahan yang dikelola oleh perusahaan kelapa sawit, kayu, dan pulpwood**-meskipun secara hukum masyarakat dan perusahaan dilarang menggunakan api untuk membuka lahan.

A new Science paper provides the first high-resolution, global picture of annual forest cover change over the period 2000 to 2012. Prior to this research, the world lacked up-to-date, globally consistent forest data-- most information about forests is years out-of-date by the time it finds its way into policymakers’ hands.
Three key findings emerge from the new maps–and they point to solutions policymakers can pursue now.
