《全球森林观察网》上线 砍伐实况全球监控

世界资源协会（WRI）、Google以及超过40个伙伴合作的《全球森林观察》（Global Forest Watch）网站测试版本于本月20日上线。各国政府、企业、公民社会和个人即日起将能透过网络，实时监控全球森林的消长。

Global Forest Watch（以下简称GFW）运用美国政府的卫星科技和 Google 捐赠的云端运算技术获取森林消长的近距离卫星影像。目前 GFW 每月更新分辨率 500 公尺距离的影像，每年更新分辨率 30公尺距离的影像。

GFW 的数据呈现了大型企业供货商的作业实况，非法采伐活动也逃不过其法眼。由于GFW是免费且公众皆可使用的网络资源，其合作组织希望能让个人也扮演「公民科学家」的角色，以公众压力督促政府和企业实施环境友善和林木的永续砍伐政策。

另外，GFW 能用电子邮件和简讯以多国语言通知用户，也让用户透过社群网站上传和分享影像，设计者希望能透过这样的机制帮助公民组成民间倡导团体。

Website Gives Real-Time Snapshot of Deforestation

A new website launched Thursday will allow governments, businesses, civil society and private citizens to monitor near real-time loss and gain in forest cover in every country around the world.

On Thursday, the World Resources Institute (WRI), a think tank here, together with Google and more than 40 other partners launched an early version of a project they’re calling Global Forest Watch.

Global Forest Watch (GFW) uses satellite technology from the U.S. government as well as “cloud computing” power donated by Google to provide close-range satellite imagery on tree-cover gain and loss. Currently, GFW provides monthly updates at a resolution of up to 500 metres, as well as yearly updates at a resolution as close as 30 metres.

Because GFW is free and publicly accessible, its partnering organisations hope it will enable private individuals to act as “citizen scientists”, able to exert public pressure on governments and businesses to implement eco-friendly policies and sustainable timber harvesting.

GFW can provide users with alerts via e-mail and text in multiple languages. It is also designed to allow users to upload and share its images over social networks, which organisers hope will help concerned citizens form advocacy groups.
