Yield

Impacts of Plantation Age, Fire and Disturbance on Catchment Yield

The problem of sustainable water resource management is a key issue confronting Australia in the 21st century. Increasing demand through increased population size, declining rainfall across parts of temperate Australia and consequently an increasing need to allocate water to maintain ecosystem health and ecosystem service provision are the dominant threats to the maintenance of an adequate supply of water to urban, peri-urban and rural communities.

Subsurface Irrigation

National Program for Sustainable Irrigation Fact sheet 2005/1

Australian studies show an average of 30% of applied irrigation water passes through the root zone without being used by the crops it is intended to sustain. This water either becomes groundwater recharge or is intercepted by drainage networks and contributes to waterway pollution. Subsurface drip irrigation has shown great potential for increasing crop yield and uniformity, while decreasing water use and environmental impact. Importantly, subsurface irrigation applies water directly to the (more)...
