Abstract:

This paper describes the technical, economic and institutional aspects of water use efficiency studies. Focus is given on the five interventions for improving the sustainability of irrigation systems and achieving water savings in Australia: (1) volume and regime of water extraction from river, water rights definition, trading and regulation of water rights use, improved distribution and control of water delivery to farms to reduce conveyance losses; (2) volume and regime of water extraction from groundwater, extraction must be matched by catchment and river recharge, and improved delivery to farms by reducing conveyance losses; (3) volume and regime of subsurface drainage, improved management to reduce leaching and drainage to groundwater, reduction of salt load to groundwater through soil storage, improved interception of subsurface drainage water and reuse through bioconcentration and extraction, and salt management schemes for subsurface drainage and groundwater; (4) reduce water extraction through greater water use efficiency on farm by reducing deep percolation and evaporation losses; and (5) improved management of surface water drainage, improved reuse, and reduction of contaminants.
