This document summarizes an integrated drought monitoring system called InterDrought that was established in the Czech Republic over 15 years with support from Czech and international agencies. The system provides real-time drought monitoring across the Czech Republic at a 500x500m resolution based on soil moisture, vegetation conditions from satellite data, long-term climate forecasts, and reported drought impacts from farmers. The goals are to raise awareness of drought risks, engage users in monitoring and research, and sustain the system to continue providing drought monitoring, forecasts and research into the future.

drought research and practical applications.

drought project
1) WHY
– drought in the past
– expected drought trends;
2) What and how
– integrated drought
monitoring system;
– 5 pillars (incl. remote
systems)
3) To whom
– education applications
– practical applications;
– research applications
4) Future challenges

3. InterDrought project
• 15 years ago
• Mostly supported by Czech agencies (GACR, NAZV…)
• International support (EU – programs – CECILIA, ADAGIO, CLIMSAVE)
• Structure founds – Operation program – partly EU, partly CR project (3 years 2012-
2015)
“Establishment of International Scientific Team
Focused on Drought Research”

34. Challenges: 1. To raise awarness and generate interest
Education
awarness,
dissemination

35. Challenges: 2. to engage and sustain it
• Since November 2014 –
more than 15 meetings with
over 1000 potential users
(from ministers to farmers)
• 10 articles in farmers journals
• (last year)
• 15 scientific papers
• (last 5 years)
• Web page: intersucho.cz
• Goal to have approximately
active 300 respondents by
the end of the year.Education
awarness,
dissemination

36. Challenges: 3. to continue research tempo and sustain it
NEAR TERM RESEARCH PRIORITIES:
• Apply in parallels to statistical also ECMWF and NCAR model based prognosis
of soil moisture with 10 – 15 days of lead time;
• Extend the operational vegetation status monitoring to the whole of Central
Europe (Slovakia will come online during 2015);
• Apply the CMIP5 projections over 21st century to assess the risks.
SUSTAINABILITY
• The Integrated system has generated considerable interests amongst users –
willingness to support it with committing time and resources;
• Base funding should be sufficient till 2020 at least
– …..some drought would help to support the argumentation 
