Irrigation Management:
The Optimization Perspective
Author(s)
M. da Conceição Cunha
Abstract
Irrigation management deals with many different decisions: the selection of
economically viable cropping patterns, allocation of land per crop, allocation of
water resources per crop, irrigation scheduling, management of irrigation deficit,
etc. Plants need appropriate amounts of water, and its distribution during the full
growing cycle has a tremendous influence on the final crop yield. This means
that managing the soil water content is crucial to obtain an optimal allocation of
water resources, supposing that the other production factors are adequate. The
use of decision models to help irrigation management appears to be an
interesting approach, as they are capable of handling different facets of such
problems (economic, physiological, environmental, etc.) all together. This paper
presents a synthetic state-of-the-art literature review of the optimization models
for these purposes. The different agricultural production functions and their
inclusion in the decision models are discussed.
Keywords: irrigation management, agricultural production functions,
optimization models.
1 Introduction
Water is a scarce good in many regions of the world, and simultaneously it is the
most important factor in some production processes, like agriculture. Supposing
that the other production factors are at an adequate level, managing the soil water
content is crucial to obtaining an optimal allocation of water resources. Irrigation
supplements rainfall and can help to overcome the main risks associated with the
uncertainty of hydrological events. In arid and semi-arid regions irrigation is
intrinsically related to the availability of water resources, and thus deficit
irrigation can occur. A benefit-cost analysis of irrigation systems should take
