Calamities Information Calamities Information SystemSystem

An integrated system for the An integrated system for the observation of climate hazard observation of climate hazard phenomena in agriculture through the phenomena in agriculture through the InternetInternet

A data combination model to estimate A data combination model to estimate the crop damage and the farmers the crop damage and the farmers compensation compensation

outlineoutline The goal is to monitor vegetation condition and The goal is to monitor vegetation condition and

to evaluate the impact of climate hazards on to evaluate the impact of climate hazards on the environment and agriculture production. the environment and agriculture production.

The System combines Earth Observation data The System combines Earth Observation data with low resolution information in a ready-to-with low resolution information in a ready-to-use form.use form.

The system alerts the users, e.g. insurance The system alerts the users, e.g. insurance companies, to crop damage and aids them to companies, to crop damage and aids them to compensate farmers who have suffered. compensate farmers who have suffered.

Night Night frostfrost in early spring, late spring/summer in early spring, late spring/summer droughtdrought and and heat excess heat excess are the calamities are the calamities which the System addresses.which the System addresses.

and subsequent damage is assessed using and subsequent damage is assessed using meteorologicalmeteorological and and Earth ObservationEarth Observation satellite data, as well as satellite data, as well as complementary information such as complementary information such as agricultural agricultural statisticsstatistics, , land use mapsland use maps, tables of , tables of phenological stagephenological stage by by region and region and ground dataground data measurements. measurements.

Many types of data, e.g. stratification maps, Many types of data, e.g. stratification maps, administrative boundaries and risk maps per type of administrative boundaries and risk maps per type of crop, are used and supplied depending on the calamity crop, are used and supplied depending on the calamity concerned. concerned.

In the case of frost and drought, data from a In the case of frost and drought, data from a meteorological network are used to aid in the meteorological network are used to aid in the interpretation of satellite imagery.interpretation of satellite imagery.

The methodology is adapted to each climate hazard The methodology is adapted to each climate hazard separately.separately.

outlineoutline The main scheme can be described as follows: The main scheme can be described as follows: Under normal conditions, a monitoring system runs Under normal conditions, a monitoring system runs

and systematically generates synoptic trends. and systematically generates synoptic trends. The monitoring system activates the alert system The monitoring system activates the alert system

whenever risk factors are detected. whenever risk factors are detected. The alert system automatically produces The alert system automatically produces

temperature maps of critical geographic temperature maps of critical geographic areas, areas,
