This document outlines an ecological risk assessment framework for the Australian irrigation industry. The objective of the framework is to provide a robust process that will assist the irrigation industry to incorporate a transparent, scientific, precautionary and ecologically sustainable approach to its management of environmental risks.
The framework is catchment-based and focuses on the difficult task of assessing the risks to multiple ecological assets from multiple hazards. This (more)...
No single methodology is used to calculate crop evapotranspiration (ETc) in Australia. This reduces confidence in the various estimates of crop water use, which are an important piece of base information that underpins much water policy.
The National Action Plan on Salinity relies on an accurate understanding of ground water recharge rates in both irrigated and dryland farming systems. Estimates of recharge rates are directly affected by estimates of crop water use as both are elements of (more)...
