The mystery of tropical deforestation — in two maps - So, more recently, scientists have turned to satellite monitoring to offer a clearer picture of which forests are actually being chopped down. In a new study published in Science, a team of nine researchers — led by Nancy Harris of Winrock International — pored over satellite data and estimated that tropical deforestation accounted for about 10 percent of all greenhouse gas emissions between 2000 and 2005.
We all know that to feed our growing population we need to intensify agriculture production. We need to produce more, sustainably, on less land.

Most of us understand the hydrologic cycle in terms of the visible paths that water can take: rainstorms, rivers, waterfalls, swamps, etc. Hydrology takes a different path through a larger volume … (RT @jsteffenson: World’s average annual evapotranspiration...
Use of remotely-sensed data in agriculture analysis enables making critical decisions to correct issues with the seasonal crop. Crop analysis such as characteristic definition, health and stress detection, change detection and understanding the effects of environmental factors can all be used to make efficient and valuable decisions in a timely manner.
The Marine Cadastre Map Gallery a collection of ArcGIS Explorer Online maps, enables ocean planners to create custom data viewers by combining authoritative data from the Marine Cadastre Data Registry with more locally relevant web map services.
