While Indonesia has taken steps to address the worst forest fires in living memory, a new palm oil alliance with Malaysia threatens to take a giant leap back.

Wouldn't it be safe to say that most World Heritage Areas have been degraded to some extent by the very fact that by being WHA they attract tourists (and all the associated development). |

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns. This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects. As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain. Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate. With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough).
View the impact in ArcGIS online: Before and After Swipe, LiDAR I and II, and Imagery.
Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment? How could this landscape have been protected and managed better or was this mudslide inevitable?

A new high-resolution global map of forest loss and gain has been created with the help of Google Earth. The interactive online tool is publicly available and zooms in to a remarkably high level of local detail - a resolution of 30m. It charts the story of the world's tree canopies from 2000 to 2012, based on 650,000 satellite images by Landsat 7. In that time, the Earth lost a combined "forest" the size of Mongolia, enough trees to cover the UK six times. |
