Water withdrawal by sector
Some key questions
• Is there enough water to feed the world in the near future (water balance, competition with other sectors)?
• What are the performances of the irrigation sector? How do they change with time?
• How does irrigation contribute to food security and to the achievement of the MDGs and WSSD targets?
• What is the impact of irrigation on the environment?

Some challenges Sub-national level information Information by river basin Non-availability or unreliability
of data for some major indicators
Definitions (harmonization) Data linked to reference Validation of data Ways to update and frequency Time series Information dissemination Sustainability of monitoring
process in relation to national monitoring capacities
“If you can’t measure, you can’t manage”… Data is expensive but indispensable
