Rehabilitation options and costs for agricultural
lands will depend on severity and extent of
damage and salinisation and on the capacity to flush out
salts and re-establish irrigation and drainage. Reclamataion
should also address agrobiodiversity and other environmental
issues and land use potentials (wetlands, recreation
etc).
There is a need to study maps of irrigated areas and
extent of damage and of soil type and terrain to assess
salinity damage.
High resolution global irrigation
maps from IWMI (jpg images) seem to show no irrigation
in coastal areas in Aceh and North Sumatra, none or
almost none in Thailand affected areas (the Thai Government
estimates affected agricultural land at 225 ha only
- this may not include plantations). This suggests
a concentration of likely effects in South-Eastern
India, West Coast and the middle of Southern Coast
of Sri Lanka (excluding consideration of lagoon systems).
