Green from Space is Earth observations from space that supports both science and other Earth observation data leading to better decision making in an increasingly complex and environmentally stressed world. This information betters our understanding of Earth lending support for sustainable development.

This episode of A Green Space - A Green Earth
This month A Green Space – A Green Earth focus on disaster mitigation and early warnings and how space based Earth observations contributes to safe-guard lives and property.
New satellite techniques such as InSAR complement GPS in unraveling in fine details crustal movements of the Earth. ESA’s GOCE gravity measurements from space will add knowledge to our understanding of sub-surface movements leading up to earthquakes. Through observing Earth from space before, during and after earthquakes we improve disaster mitigation and early warnings.

Last Month: Climate change and sea level forecasting is the topic of A Green Space – A Green Earth in July.
Sea level forecasting relies on both Earth observation from space as well as data from coastal tide gauges. Climate change makes sea level estimates in the future very uncertain. What we need are sea level forecasts equivalent to weather forecasts.
The world is populated in a growing number of mega cities, cities with more than 1 million inhabitants, and people are migrating towards the coastal areas, making inhabitants in general, more vulnerable to natural hazards like sea level rise, storm surges and tsunamis.
