Within a framework of water scarcity, DI strategies could
be key in possible future scenarios of water shortage,
enabling the maintenance of agro-ecosystems under limiting
conditions. In this context, Severini and Cortignani
(2008) proposed a positive mathematical programming
model for studying the viability of deficit irrigation
strategies, arguing that these techniques effectively describe
the negative impact of decreasing water availability on farm
economic results. In addition, Azaiez (2008) developed an
integral dynamic programming model for analysing the
effects of DI in order to increase the irrigated area at the
expense of reducing the crop yield per unit area, considering
that the effects of DI are closely related to the amount
of water applied for each phenological period.
