ADVANTAGES AND DISADVANTAGES OF IRIGGATION: FOCUS ON SEMI-ARID REGIONS
Abstract
The main goal of this study was to present positive and negative influences of irrigation process, as one of the widespread applied method in the melioration.High population growth demands high food production and thus stimulates modern massively agricultural economy.Irrigation as remarkable measure from ancient time and recently became over exceed, and these concomitant negative influences should be reduced or escaped.This publication is a survey of appropriate and sustainable irrigation methods based on the improvement of ecological conditions and optimizing the use of land and water resources.Water deficit is especially expressed in semi-arid regions and requests rational use of water.Thereby, macrophytes, as well known intermediates in water purification are presented in cleaning of municipal and drainage water with the aim to enable reuse of that water again in irrigation or plumbing.Bio-engineering infiltration constructions (BIC) and floating bioplato with macrophytes are indicated as environmentally sustainable and economically suitable methods in wastewater treatment peculiarly in a semi-arid area suffering from drought.
