Australian Development Gateway

The Australian Development Gateway (ADG) strives to support members of the development community in their efforts to reduce poverty and enhance sustainable development in the Asia Pacific region. The site has been created with participation from members of government, private, academia and non-government organisations. User feedback mechanisms have been incorporated to guide future directions of the site. The site is optimised for low bandwidth access to enable the widest participation throughout the Asia Pacific region.

Growing trees on salt-affected land

This impact-assessment study of an ACIAR research project 'Tree growing on salt-affected land in Pakistan, Thailand and Australia' found that although the research clearly demonstrated that growing short-rotation trees can result in reclamation of abandoned land, adoption of the outcomes has not been high.

Salinity and waterlogging are significant problems in a wide range of agricultural areas throughout the world. It has been found that some Australian species, including species in the genera Eucalyptys and Acacia, have adapted to thrive in these conditions.

Bioremediation using such trees has often been suggested as a potentially lower-cost alternative to physical methods, however adoption has not been high. This is probably due to the development costs and relatively long investment periods before seeing a return.
