Multidisciplinary approach of information system for integrated water resources

management and biodiversity data gathering: an example for benefits

from cross-linking project cooperation

Climate Change:

Sea level rise will lead to:

• Increased coastal erosion

• Changed sedimentation

• Ecosystem changesSource: IPCC 2007

The Project „Sustainable Management

of Coastal Forest Ecosystems in Bac

Lieu province“:

• Funded by the German Ministry for

the Environment

• Operative since May 2009

GTZ, Bac Lieu, Vietnam

Main objectives:

• Coastal forest rehabilitation

• Biodiversity enhancement

• need for high resolution

mapping of current species

Track&Tracing biodiversity in Mangroves

is challanging:

• most unfavourable environment for

pen+paper recordings

• GIS-referencing only clusterwise

possible

• information gathering only feasable

with several people

• data digitilization always a potential

source of error

Using “rugged mobile phones” for GIS-

referrenced biodiversity data gathering:

• water- and shock-resistant

• mobiles are always at hand and

usually operational (fully charged)

• single spot entries are possible (no

transsect clusters needed)

• one person can do the job

• recordet data can not be lost

• no additional data digitilization

needed

Satellite images:

• limited availability of updated high

resolution images

• cloud covering

• very expensive

just providing one layer of reference

information (2 dimensional, no

topography, no socioeconomic data,

no hydrology etc...)

GTZ, Bac Lieu, Vietnam

Page 9: Increased coastal erosion • Changed sedimentation€¦ · Cambodia, into South Vietnam Delta: 70,000 km² Challenge: cross boundary issues, dam building in North, China not in MRC,

07.05.2010 Page 9

As GTZ-Bac Lieu we are piloting the introduction of

different information layers available from WISDOM for generating analytical maps

No extra purchase for updated “own” satellite images needed.

No own additional research regarding cross-linking information needed (e.g. hydrology, topography, socio-economics etc).

National Water Ressources Strategy (2020, MONRE)Major Challenges identified by ADB (amongst many):

„The collection, management and archive of information on water and land resources are still dispersed. Data in different agencies is inconsistent and not exchanged among state agencies“

„The monitoring, warning, and information systems for water quality, … flood and drougt prediction, .. have not been properly developed“

Implementation measures (amongst many):

„Set up of general Land- and Water Information Systems, flood and drought monitoring systems, flash flood warning systems …“

Main synergies from the cooperation (1):

• GTZ will have projects running in all coastal provinces and WISDOM covers Mekong Provinces since 3 years

• Different disciplinces complement each other value adding

• Data exchange, with low maintenance costs (Open Source)

• Data dissemination independent from location, soft- and hardware

• WISDOM provides neutral platform for data exchange – data ownership can be ensured

• Joint standard allows easy map calibrations, valididations and comparability of results

Main synergies from the cooperation (2):

• More easy access for further RS data

• Bunch competences to approach threats of the Mekong Delta

• Increased efficiency for spatial and non-spatial data management

• Semantic enabled data identification

• Automatic integration of spatial data

• Easy extendable to other regions

07.05.2010 Page 32

Planned steps of cooperation:

• Applying the information system together

• Exchange of information, data, capacity building

• Introducing the WISDOM data standard for data originating from CoastalManagement Projects

• Jointly developing and applying one method of landcover classification
