Geo-information needs

• P-12: Farming activities – Baseline crop health / animal health
• DO-30: Impact on nearby industries (in particular agriculture)
• CA-8: Farming activities – confirm return to baseline conditions for crops / animals

Description

To analyse the impacts of raw mining activities and in case of negative effects to react properly, it is important to get information on crop health of surrounding farming activities that might be affected. EO can support this activity with crop health monitoring methods that are used to classify crops as well as monitor health.

The assessment builds upon various parameters, so-called Vegetation Indices (VI) that are derived from different band combinations satellite imagery. These are e.g. the Normalized Vegetation Difference Index (NDVI), the Leaf Area Index (LAI), and the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR). Based on unique spectral characteristics the calculated parameters indicate different crop types and further information on the identification, detection, quantification and mapping of crop diseases.

Design, Construction & Operations:

• Assessing crop productivity and crop health to demonstrate whether there are impacts once mining commences

Mine Closure & Aftercare:

• Assessing farming activities after mine closure to assure that there is no impact on farming activities

Accuracy / constraints

Thematic accuracy:

Crop type, >85% accuracy for major classes; growth peak of crop types; crop health.

Spatial accuracy:

Dependent on input-pixel resolution. Using open data a resolution of 10 m is possible.

Accuracy assessment approach & quality control measures

Usually, an accuracy of 80–90 % is reached.

Frequency / timeliness

Observation frequency:

Every 1 or more days, depending on satellite.

Timeliness of delivery:

Within 5 (working) days of sensing.
