CONTaCTs 1. The ProjecT GEnERAL PROjECt IntRODuCtIOn Key Issues and Challenges in the Mekong Delta the Mekong Delta is formed by the nine arms of the Mekong River, which all drain into the South China Sea. It comprises an area of 40,000 km2 and offers natural resources for over 17 million inhabitants living in 13 of the 58 provinces of Vietnam (figure 1). frequent floods and droughts, limited availability of drinking water, increasing water pollution, and loss of species and habitats, such as the decrease of mangrove ecosystems, all have negative effects on people’s lives. Strong population pressure and the first impacts of climate change pose increasing challenges for the population of this fast developing region, and hence for the planning authorities in the delta. rise induced saltwater intrusion and soil salinization leading to a decrease in agricultural yields and to an expected increase in tropical storms, and, generally, strong population and economic growth leading to more pressure on natural resources and the livelihood of the population. national and regional authorities face the problem of ensuring the sustainable management of land and water resources in the Mekong Delta. thus, a key aspect for planning authorities is the generation and distribution of water–related information for the delta. though people have adapted for centuries to seasonal flooding in the delta, they are facing numerous challenges which are constantly intensifying. Amongst them are an increase in the number of extreme floods, expanded drought periods, accelerating water pollution, sea level 1 1:350,000 Vietnam - Mekong Delta - WISDOM Testsites 536278 105°0'0"E 586278 105°30'0"E 106°0'0"E 636278 686278 106°30'0"E 107°0'0"E China Myanmar Ha Noi Laos 1205332 1205332 Bay of Bengal Vientian Yangon Vietnam Thailand Bangkok Andaman Sea Phnom Penh Ho Chi Minh City Gulf of Thailand TA M N O N G South China Sea Cambodia Cambodia Ho Chi Minh City !

Introduction to the WISDOM project 2 686278 107°0'0"E WISDOM Project Coordinated by DLR www.wisdom.caf.dlr.de For questions contact: [email protected] phone: 0049-8153-28-3280 © DLR 2008 In the first project phase (2007 – 2010) a prototypical Water- and Land-Information System was developed. Information System is a technical term describing a knowledge cluster built up from different research fields within the project plus a physically existing web-based information system. In the WISDOM Information System, data and information from project disciplines like hydrology, geochemistry, socio-economics, geography, and earth observation are constantly integrated. Fig. 2 WISDOM project group at WISDOM II Kickoff Meeting in Ho Chi Minh City the potential user is not only able to visualize all this information but can use it to analyze special Mekong Delta related questions as well. In the second project phase (2010 – 2013) the project network comprises seven German and eight Vietnamese research institutions, six German small- and medium-size enterprises as well as eleven associated partners. there are two major goals for this second phase. first, there is the challenge to answer numerous research questions related to climate change as well as land and water management, which is being addressed by numerous senior scientists as well as 14 PhD students in research topics from disciplines such as environmental science, remote sensing, GIS, hydrologic modelling, socio-economics, climate change resilience and adaptation, etc. Secondly, the WISDOM Information System is to be implemented in Vietnam. Capacity building activities are carried out jointly by project partners, stakeholder and users to achieve sustainable knowledge dissemination as well as the long-term use of the system.

Earth Observation Monitoring basin Characteristics Water Quality, Pollution Analyses of Legal System Water Quantity, Demand, Reliability Institutional Mapping InfORMAtIOn SyStEM the WISDOM Information System is the central access point for all WISDOM data products generated by the project’s partners (figure 4). the WISDOM Information System is a webbased Geographic Information System with data ingestion and operational data processing capabilities which follow widelyagreed international standards. the focus is on employing opensource technologies in order to satisfy current Vietnamese government It strategies, reduce installation costs and permit further adaptations to meet necessary project requirements. the implemented client-server technology with components consisting of a spatial database, a java web application and several services can be installed at multiple locations. According training Capacity building Climate Change Analyses Landuse Change Social Change Multi-disciplinary data sources form the input for the WISDOM Information System Fig. 4 of functions for data querying and visualization in a web-based application. the main idea is that combining historical and nearreal-time data from different science fields will facilitate user analysis of water related question (for example, “how does to the project-wide data standard developed in the beginning of the project, the data integration process is fully automated to enable partners to import or update their data easily. After data ingestion the WISDOM Information System provides a set 5 the current inundation situation differ from past flood events or from different flooding scenarios from hydrological modelling?”). End users can directly access the functions of the WISDOM Information System via the Internet using standard browser software. In addition, the implementation of services compliant with OGC (Open Geospatial Consortium) standards provides access to WISDOM components and data even for those using non-WISDOM software. because of this compliance with open standards the WISDOM Information System can integrate new data sources easily and play a major role in establishing a Vietnamese spatial data infrastructure. how can the success of the WISDOM Information System be ensured? building both capacity and acceptance are important tasks extending beyond the technical development of an information system. there have been several activities, still ongoing, between DLR and Vnu-ItP (the Information technology Park of the Vietnam national university ) and including all other partners in Technical User Training Workshop Fig. 5 6 Stakeholder Meeting in Can Tho City Contacts the WISDOM Information System Fig. 6 Verena Klinger ADDRESS Germany and Vietnam to jointly design, build, develop, and ensure maintenance of the system in Vietnam. Several training sessions (figure 5) covering all aspects of information system design as well as geodata management provide the background for internal project collaboration. further activities to ensure the final successful implementation of the WISDOM Information System include defining a sound operator concept enabling Vietnamese stakeholders and scientists to continuously fill the German Remote Sensing Data Center (DfD) German Aerospace Center (DLR) Oberpfaffenhofen, Germany system with further information and maintain system operation. frequent exchanges with stakeholders (figure 6) at different administrative levels clear the path for the final acceptance and further development of this planning tool.

Satellite-based imaging sensors visualize the surface in spectral ranges beyond what the human eye can see. Socalled passive sensors measure reflected sunlight in the optical and infrared regions of the electromagnetic spectrum. Active sensors utilize their own source of radiation, for example in the The Mekong Delta is the focus area of the WISDOM project Fig. 7 8 microwave range, to measure the signals reflected back to the sensor, and since clouds, fog and rain are transparent to microwaves, a radar sensor can see through clouds. Remote sensing product generation the German Aerospace Center (DLR) in close cooperation with the university of Würzburg is synergistically utilizing passive and active satellite imagery from a variety of sensors to derive land cover and land use information at different spatial scales for the entire Mekong basin and the Mekong Delta, and at especially high scales for priority areas. Such information products have been generated for different periods over recent decades, allowing an analysis of changes in the investigated areas. they are valuable input for detecting natural changes, for example, those caused by floods and storms, and understanding the adaptation strategies of the population over recent decades, like urbanization or agricultural intensification. the Fig. 8 Sediment concentration maps derived from optical remote sensing data – zoom in on river channel in the north of Can Tho province running into a main river arm of the Mekong Satellite image: © 2007 DigitalGlobe team of Würzburg-DLR and the EOMAP company in cooperation with the GIS and Remote Sensing Research Center (VAStGIRS) are utilizing active radar imagery and passive optical images, respectively, to continuously map inundated areas in the Mekong basin and Delta to obtain time series of so-called water masks which trace the flooding occurring primarily during the wet seasons (figure 9).

Combining and merging these data with other types of information also allows for the generation of higher value information products (figure 11). Inundation and soil moisture maps as well as land cover monitoring products are major inputs for developing and calibrating robust models for flood prediction. Analysis of land cover and land use changes together with socio-economic statistical data helps to reveal the adaptation strategies of the local population 3 4 — Mangrove distribution and land use map generated from radar and optical remote sensing imagery 4 11 Mekong Delta - Inundation as a Function of Time 2008 1:250.000 105°30'0"E 106°0'0"E 10°0'0"N 10°30'0"N 10°30'0"N 11°0'0"N 11°0'0"N 105°0'0"E 10°0'0"N 10°0'0"N and the impacts of climate change. topographic information derived from high resolution satellite images combined with vulnerability calculations at the household level enables the derivation of such products as flood vulnerability maps. time series of inundation maps are utilized to derive information about regularly inundated areas and to discriminate them from hazardously flooded areas. With that knowledge, flood information products can be generated as high-level reports providing information for populated places, infrastructure, or areas with different land cover types affected by hazardous flooding, for example.

In order to accomplish this, products are constantly validated in the field (figures 12, 13) and calibrated accordingly. Of utmost importance, however, is securing continuous future satellite data acquisition. While especially high resolution data are costly, most other data utilized for resource monitoring in WISDOM are continuously available at relatively low cost.

GfZ also develops prototype river buoys equipped with GPS for continuously recording water level and water movement (figure 15). this novel inland monitoring technique provides solutions for large inland water bodies where standard monitoring is difficult. It also offers additional monitoring options like movement velocities and flow direction changes. Within the project frame of WISDOM the data are used for detailed calibration of hydrodynamic models of the investigation areas in tam nong and the whole Mekong Delta downstream of Kratie in Cambodia, thus including the tonle Sap lake system. the latter models were developed in close cooperation with SIWRR, the Southern Institute of Water Resources Research. these models will in turn be used for planning tasks which include planning flood defense structures and the operation of sluice gates and pumps, as well as for a first time quantification of nutrients carried in flood sediment which enter fields on the floodplains.

In terms of a contribution to the sustainable development of the Mekong Delta, unu-EhS and InRES are actively involved in capacity building activities and are in continuous dialog with relevant stakeholders in the delta. to analyze endocrine disruptors, InRES partnered with the Itb (Institute of tropical biology) in ho Chi Minh City and organized a two-day workshop on endocrine disruptors with hands-on training for the representatives from Departments of natural Resources and Environment (DOnRE) in ho Chi Minh City, Can tho, hau Giang, Dong, and nai, from the Department of Science and tech- Contacts In Situ Water Quality Sampling in WISDOM Dr. fabrice Renaud ADDRESS united nations university Institute for Environment and human Security unu-EhS, un-Campus bonn, Germany PhOnE +49-228-8150211 EMAIL [email protected] Ky Quang Vinh ADDRESS Center for natural Resources and Environmental Monitoring of Can tho City Climate Change Coordination Office of Can tho City Can tho City, Vietnam PhOnE +84-0907-619065 EMAIL 20 [email protected] VuLnERAbILIty ASSESSMEnt In WISDOM Objectives the objective of this work package is to conduct vulnerability and risk assessments for water-related hazards in the Mekong Delta and to evaluate resulting adaptation options. Vulnerability related information as well as assessment and evaluation guidelines are fed into the WISDOM Information System. In order to allow for proactive integrated water resources management, there is great need to understand how vulnerabilities to water-related hazards emerge and how they Marginal settlement with high flood exposure, Can Tho Fig. 20 21 differ among various socioeconomic groups as well as with respect to different types of hazards, such as floods (figure 20), salinization, water scarcity, storms and river bank erosion. based on this knowledge, different strategies for adaptation are evaluated in collaboration with relevant stakeholder groups in Vietnam and the development of innovative adaptation strategies integrating formal and informal mechanisms is promoted (figure 21). In order to capture the different biophysical and socio- economic settings within the Mekong Delta, rural and urban profiles are compared among the case study provinces Dong thap (rural, prone to annual flooding), Can tho (urban and peri-urban, tidal and urban flooding) and tra Vinh (rural, salinization and coastal storms). 22 Adaptation to high flood levels in the Northern Mekong Delta Fig. 21 Products for the WISDOM Information System the vulnerability assessment contributes a variety of data sets to the WISDOM Information System combining assessment findings from social as well as engineering sciences. based on in-depth interviews and a household survey in three case study areas (covering roughly 1400 households), vulnerability profiles are developed which are represented in schematic figures highlighting archetype vulnerability pathways as well as in maps showing the spatial distribution of the main vulnerability parameters, hence allowing for the identification of vulnerability hotspots and priority areas for action (figure 22). based on hydrological modelling, flood hazard maps will be generated and combined with physical asset and vulnerability maps to derive flood loss maps and aggregated risk maps. this cascading combination of data sets and maps allows the user of the WISDOM Information System to access information at various levels of aggregation (ranging from single components such as Fig. 22 Participatory vulnerability assessment with local farmers, Tra Vinh Province 23 the map of one particular vulnerability parameter in one specific case study area all the way to the comprehensive and aggregated risk maps which merge physical hazard scenarios with socio-economic vulnerabilities). On the basis of the knowledge generated through these assessment techniques, a comprehensive (digital) handbook with quality criteria for different adaptation options is being developed. In addition, checklists are provided which compare the advantages and disadvantages of different adaptation options (for example, the erection of a dyke system vs. resettlement for a given community) and which help to assess the feasibility of potential options. Sustainability of the products Contacts Vulnerability Assessment in WISDOM Dr. jörn birkmann ADDRESS In order to encourage sustainable use of the products generated, an iterative process of needs assessment and joint method development with partners from the political as well as scientific communities in Vietnam and particularly the Mekong Delta has been ongoing since 2008. this ensures relevance as well as political support and the continued application of the assessments developed. this exchange will even intensify as the project advances and more and more results of ongoing assessments will become available and used to devise implementation measures and to support decision making. the most important formats for fostering this exchange are meetings with the relevant planning agencies, expert workshops, joint science seminars with partners from academia, and joint field campaigns, all of which remain an important basis of this work. 24 united nations university Institute for Environment and human Security unu-EhS, un Campus bonn, Germany PhOnE EMAIL +49-228-8150208 [email protected] Dr. Le Viet Dung ADDRESS Vice Rector for International Relations Can tho university Can tho City, Vietnam EMAIL [email protected] SOCIO-ECOnOMIC RESEARCh In WISDOM fields of socio-economic research in WISDOM the socio-economic research addresses the specific challenges, policies and practices of water resources management in Vietnam and, more precisely, in the Mekong Delta. patterns, as well as on water quality. Moreover, local adaptation strategies and related changes in the specific water-related livelihoods of the Mekong Delta population are examined (figure 23). With regard to the specific challenges, statistical data on socio-economic transformation processes are being collected. Data analysis focuses on the impact of processes like economic growth, urbanization, industrialization and modernization, on water usage and consumption Another branch of research investigates the water policy framework, related sector reforms, and the knowledge production of central and local government agencies. Intensive fieldwork on the implementation of policies and reforms as Rural water supply Fig. 23 25 well as knowledge dissemination and sharing is undertaken. In view of understanding water resources management practices, case studies are carried out in Can tho City, which is located in the heart of the Mekong Delta. these case studies make it possible to identify the various actors as well as their respective level of engagement and interaction at different scales of operation. Specific attention is given to the interface of state management, private businesses, research organizations, water user groups and, to a certain extent, donors. there are a number of socioeconomic research subprojects, including: flood control: planning and implementing dyke systems Water supply: policy and implementation in rural areas Water engineering: changing interfaces between water bureaucracies and hydraulic construction businesses Water research: knowledge production, knowledge assets and regional collaboration Decentralization and participation: local water management and water user groups Water legislation: legal framework and law enforcement. 26 Household interview with local farmer Fig. 24 from research findings to presentation the findings of these empirical studies provide the basis for understanding the institutional complexity and transition of water resources management in Vietnam. Moreover, data and results are provided in the form of tables, organizational flowcharts, maps, pictures and statistics (figure 25) and are being transferred to the WISDOM Information System. both visualization of empirical findings in the form of figures and spatial analysis of the data are used to generate new products and knowledge. these enable future users to access a complex set of information on various aspects of water resources management at both national and local administrative levels.

In terms of research output, a series of academic writings are being produced; these include eight PhD theses to be published in the form of books, as well as working papers and journal articles. Publications are in English and Vietnamese and a dissemination strategy, in particular for Vietnam, has been developed. these products also aim at strengthening the linkage necessary for interdisciplinary research and contributing to current scientific debates on IWRM (Integrated Water Resources Management) and sustainable development in Vietnam and beyond.
