Landscape Salinisation and Management: An Australian Perspective = تملح الأراضي وإداراتها: وجهة نظر أسترالية

Hoey, D.

Australian landscapes are facing an increasing salinisation threat. It is estimated that 2.5 million hectares are affected by land salinisation, and this area is expected to triple by 2050. Federal and State governments have jointly developed a policy framework to address this issue, with each state refining their own salinity management strategies within this framework. Scientific assessment and modelling underpin these salinity management strategies, though socio-economic considerations are also important. Landscape salinity assessment techniques used in the Australian context are outlined, and examples of salinity hazard and recharge mapping at the landscape scale described. Current developments in both recharge assessment, and groundwater flow modelling in Australia are described, and the use of these models in underpinning state salinity strategic planning discussed. The salinity management ‘toolkit’ is discussed. The progression from initially applying engineering solutions to deal with the symptoms of salinisation; to dealing with the causes of salinisation; to developing an integrated catchment management approach; to including a stronger emphasis on market-based economic measures; and the importance of over-arching Catchment Blueprints, is described in detail.The application of knowledge and experience gained through the management of Australian land salinisation to other countries is discussed in the context of the salinity problem in the Sultanate of Oman.
