• IPCC
– statistically significant variation in the mean state of the climate or its variability, persisting for an extended period (typically decades or longer)
• UNFCCC
– A change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

(IPCC, 2007)
• Climate change effects agricultural water resources management including agricultural land use change, cropping periods, cultivable land, water yield, and flooding.
• Especially, increasing storm and drought events requires more intention to irrigation structures operation and maintenance.

• Water use is impacted by climate change, and also, more importantly, by changes in population, lifestyle, economy, and technology.
