Product Description

Our planet contains an abundance of water. Why is it then that the availability of usable water resources has been identified as a key issue for sustainable growth for our future? Around 97% of the planet's water supply is contained in our oceans. We all know that the high salt content of seawater makes it useless for irrigation or drinking. What is often forgotten is that all water and soil contains salts. The poor use of these resources can cause an accumulation of salts which can be as deadly to plants and animals as seawater. Salination, the 'White Death', potentially affects 40% of the world's agricultural production. This program, through the use of animations, diagrams and examples, provides a visually-engaging teaching resource. Topics discussed include: the problem of rising salinity in agriculture; damage to buildings and industry caused by salination; salinity and its causes, including tree clearing, and monoculture cropping; poor irrigation techniques and salination; the rising water table; remediation processes; improved irrigation techniques; reafforestation of cleared agricultural and range lands; diversification in land use.
