| Zusammenfassung |
| The 2004 Indian Ocean tsunami caused damages to coastal ecosystems and thus
affected the livelihoods of the coastal communities who depend on services
provided by these ecosystems. The paper presents a case study on evaluating
and mapping the spatial and temporal impacts of the tsunami on land use and
land cover (LULC) and related ecosystem service supply in the
Phang Nga province, Thailand. The method includes local stakeholder
interviews, field investigations, remote-sensing techniques, and GIS.
Results provide an ecosystem services matrix with capacity scores
for 18 LULC classes and 17 ecosystem functions and services as well as
pre-/post-tsunami and recovery maps indicating changes in the ecosystem
service supply capacities in the study area. Local stakeholder interviews
revealed that mangroves, casuarina forest, mixed beach forest, coral reefs, tidal inlets, as
well as wetlands (peat swamp forest) have the highest capacity to supply
ecosystem services, while e.g. plantations have a lower capacity. The
remote-sensing based damage and recovery analysis showed a loss of the
ecosystem service supply capacities in almost all LULC classes for most of
the services due to the tsunami. A fast recovery of LULC and related
ecosystem service supply capacities within one year could be observed for
e.g. beaches, while mangroves or casuarina forest needed several years to
recover. Applying multi-temporal mapping the spatial variations of
recovery
could be visualised. While some patches of coastal forest were fully
recovered after 3 yr, other patches were still affected and thus had
a reduced capacity to supply ecosystem services. The ecosystem services maps can
be used to quantify ecological values and their spatial distribution in the
framework of a tsunami risk assessment. Beyond that they are considered to
be a useful tool for spatial analysis in coastal risk management in Phang
Nga. |
