Soil salinity

Inundation by saltwater, temporarily or long term, has caused serious soil salinity difficulties. In some instances, agricultural land has been rendered unfit for continued use in the short to medium term. Where forests and trees have been adversely affected by the increase in soil salinity, salt resistant tree species exist and can be planted to assist in rehabilitation of inundated lands.

Needs for action

A systematic and comprehensive assessment is required that addresses:

  • areas and severity of damage on agricultural and forested land inundated by salt water;
  • strategies to be developed to rehabilitate soils affected by increased levels of salinity.
