Fires
Active fire products from the Moderate Resolution Imaging Spectroradiometer (MODIS) for the last 24 hours up to the last 90 days.
Fires legend
DOPA Explorer is the Joint Research Centre’s web based information system on the world's protected areas, which helps the European Commission and other users to assess the state of and the pressure on protected areas at multiple scales. Active fires are located on the basis of the so-called thermal anomalies produced by them. The algorithms compare the temperature of a potential fire with the temperature of the land cover around it; if the difference in temperature is above a given threshold, the potential fire is confirmed as an active fire or "hot spot." Global Wildfire Information System (GWIS) uses the active fire detections provided by the NASA FIRMS (Fire Information for Resource Management System).

Floods
Global historical and current flood events derived from news, governmental, instrumental, and remote sensing sources from the Dartmouth Flood Observatory and Flood hazard 100 year return period Layer from Global Flood Awareness System
Floods legend
Flood hazard 100 year return period
Inundated areas for flood events with a return period of 100 years, based on GloFAS climatology. Permanent water bodies derived from the Global Lakes and Wetlands Database and from the Natural Earth lakes map (naturalearthdata.com).
- Shallow (less than 1m)
- Moderate (between 1 and 3 m)
- Deep (between 3 and 10 m)
- Very deep (permanent water)
Droughts
The indicator shows the risk of having impacts from a drought, by taking into account the exposure and socio-economic vulnerability of the area, with particular focus on the agricultural impacts.

Risk of Drought Impact
The indicator shows the risk of having impacts from a drought, by taking into account the exposure and socio-economic vulnerability of the area, with particular focus on the agricultural impacts. Formerly known as Likelihood of Drought Impact (LDI), it differs from the latter in that soil moisture anomaly is now included and updated every ten days (dekad).

The NOAA Coral Reef Watch (CRW) twice-weekly 50-km Sea Surface Temperature (SST) Anomaly product displays the difference between today's SST and the long-term average. The scale goes from -5 to +5 °C. Positive numbers mean the temperature is warmer than average; negative means cooler than average. More at NOAA Website Please zoom out to see the layer

Inland surface water
Areas of permanent and seasonal surface inland water and their changes over time (1984 - 2018) are expressed in km2 and percentages.
| Area (km2) of permanent surface water (2018) | Area (km2) of seasonal inland water (2018) | Net change (km2) of permanent surface water (2018 – 1984) | Net change (km2) of seasonal inland water | Net change (%) of permanent surface water (2018 – 1984) | Net change (%) in surface area of seasonal inland water |

Sometimes Water
Always Water
The Water Occurrence dataset shows where surface water occurred between 1984 and 2018 and provides information concerning overall water dynamics. This product captures both the intra and inter-annual variability and changes. The occurrence is a measurement of the water presence frequency (expressed as a percentage of the available observations over time actually identified as water). The provided occurrence accommodates for variations in data acquisition over time (i.e. temporal deepness and frequency density of the satellite observations) in order to provide a consistent characterization of the water dynamic over time.
Water Occurrence Change Intensity (1984-1999 to 2000-2018)
Decrease
No Change
Increase
The Water Occurrence Change Intensity product shows where surface water occurrence increased, decreased or remained invariant between 1984 and 2018. Both the direction of change (i.e. increase, decrease or no change) and its intensity are documented. The occurrence change accommodates for variations in data acquisition over time (i.e. temporal deepness and frequency density of the satellite observations) in order to provide a consistent occurrence change measurement.

The Water Transitions map documents changes in water state between the first year and the last year of observation.
Forest cover
Forest cover (2000), forest loss (2000-2018) and forest gain (2000-2012) statistics are expressed in km2 and percent of the ecoregion area. Maps with the location of the areas of forest gain and loss are also provided.
