The coastal areas of the Region affected by the tsunami present highly diversified human activities, from inland fresh water rice-based systems and wetlands to mangrove and coastal strips used primarily for fishing.

Much irrigation (mainly rice) is practised in the coastal low-lying areas where drainage is often difficult due to lack of slope. Assessment of the impacts of the tsunami address the damage by flooding (duration), erosion, scouring, deposition and salinity in these fragile tropical agro-ecosystems.

Focus of assessments
	Assessment of the land and water resources and agriculture-related damages
	Classification and mapping of the different types, extent and severity of damages
	Identification and prioritisation of the types of rehabilitation/intervention (short, medium and long term)
	Salinity assessment and monitoring
	Estimates of the costs of the proposed rehabilitation/interventions
	Information & communication
	National and regional assessments as basis for integrated frameworks for action.
