Regional Mean Evapotranspiration (PET) Variability

Regional Mean Evapotranspiration (PET) Variability

As an increasing trend in climatic variability in the region becomes evident, irrigation systems and methodologies are shifted to compensate for rainfall shortages and temperature fluctuations in order to maintain and improve current levels of agricultural productivity.

The numerical representation of the occurrence of evaporation and transpiration given ideal water conditions (PET), compared with precipitation data allows analysts to predict the expected aridity conditions that affected populations are likely to face in the coming stages of their agricultural cycles, forming an essential part of the development of early warning systems in preparing for program operations.

Crucially, the determination of how much potentiality the atmosphere has to withdraw moisture from the soil and vegetation has a significant role to play in the development of food security programs, with variability being the key factor in determining crop planning and irrigation scheduling components.
