(1) Climate change and food
(agriculture)?Agricultural science and practice
requires highly sophisticated scientific
approaches and tools for
* STRATEGIC DECISIONS
* ENOUGH AND GOOD QUALITY FOOD
Summer University on Information Technology in Agriculture …., Debrecen (Hungary), 19-22 August 2006Summer University on Information Technology in Agriculture …., Debrecen (Hungary), 19-22 August 2006
(2) Agricultural planning- strategic (long term) and tactical (less than 10 days) is needed to „protect” agricultural production from
climate-related and other risks
Goals1) Farmer’s2) Manager’s2) Scientist’s
CLIMATE/WEATHER (INFORMATION)
Summer University on Information Technology in Agriculture …., Debrecen (Hungary), 19-22 August 2006Summer University on Information Technology in Agriculture …., Debrecen (Hungary), 19-22 August 2006
(2) Climate disasters
1) Extreme events (tornadoes, flash, floods and severe thunderstorms, effect of prolonged drought and floods) and
2) Regional climate anomalies (mesoscale storms, small-scale severe weather phenomena).
Summer University on Information Technology in Agriculture …., Debrecen (Hungary), 19-22 August 2006Summer University on Information Technology in Agriculture …., Debrecen (Hungary), 19-22 August 2006
(2)
Assessing and forecasting the impacts of short-term climate variability and weather risk as well as their relationship to extreme events could help TO mitigate the effects of climate variability and scheduling agricultural activities.
INFORMATION (dimension of reliability and time) ---- STRATEGIC
