Satellites for peat's sake

A press release from the European Space Agency: Satellites can help us to safeguard nature’s richest carbon storehouses – peatlands. Peatlands make up just 3% of land but capture twice as much carbon as all forests combined. They are also an important source of drinking water and provide a home to many rare and threatened animals and plants.

Ecosystems work best when left intact but these wetland areas are being threatened by human exploitation, resulting in vast carbon emissions, frequent and uncontrollable fires and loss of valuable landscapes.

 Rezatec in Oxfordshire, UK, supported by ESA’s Integrated Applications Promotions programme, in the Peat spotter project will give landowners an easier and cheaper way of calculating the potential economic value of conserving or restoring their peatlands and monitoring the results of their investment.

“Peat spotter helps landowners to manage their peat resource more sustainably through mapping the area, measuring the carbon it contains and monitoring how its integrity is changing over time,” says Patrick Newton, CEO of Rezatec.

To do this, satellite imagery is used to locate and create initial mappings of peatlands. This information is enriched with ground data collected by field agents using handheld devices. An app prompts users in the field for measurements, satnav adds location information, and the data are then sent directly to a centralised office via satcom for analysis. The new approach is a cost-effective way of measuring peat extent and how intact it is over wide and potentially remote areas that are otherwise expensive to measure or inaccessible from the ground....
