Planned Impact
Our research will contribute to the knowledge base both locally and globally, in both academic and applied terms. Key project outcomes include (1) a multi-disciplinary assessment framework of the viability of BGI to promote flood resilience in Can Tho; (2) an integrative urban flood model; (3) a holistic assessment (including monetary valuation) of improvements to flood risk management and natural capital resulting from BGI in Can Tho, Viet Nam.
ValBGI has a clear impact strategy with a number of well-defined beneficiaries in the case study city of Can Tho and beyond. These are:
- Local flood, disaster, environmental and urban managers in Can Tho, such as the People's Committee and the City Resilience Office (CRO) of Can Tho;
- National flood, disaster and environmental managers in Viet Nam (Ministry of Natural Resources and Environment) who will benefit from the development of a multi-disciplinary framework to assess BGI measures;
- Environmental managers and NGOs, predominantly in Viet Nam but also in the UK and internationally, benefiting from improvements in BGI-related natural capital assessments. Both the methodological advancements plus elicited and collated costs and benefits will be provided.
- Public and wider society: This project will make local communities central to the evaluations of BGI measures in the case study location.
- Students and early career researchers at Can Tho University will be given the opportunity to run mini student projects. In this way, ValBGI will contribute towards building research capacity in Viet Nam for future ecosystem service assessments.
- Academia in Viet Nam and globally will benefit from the expected scientific contributions regarding (1) high-resolution modelling tools and scientific evidence supporting city-scale application of BGI for flood risk management; and (2) the spatially explicit assessment and valuation of BGI related changes flood risk and urban natural capital.
The project's impact strategy consists of a variety of routes to ensure high and relevant impact of all components of the research outcomes. These routes are:
1. Advisory board to be set up and consisting of key decision-makers, urban and environmental managers and planners and representatives from relevant local community groups to maximise the impact of the project outputs for practical flood management and appropriate urban planning in Can Tho. The board will convene in one-day meeting during the regular project meetings.
2. Innovative locally derived engagement activities, which will need to be tailored to the specific needs of different stakeholder groups (to be assessed in the project). Some suggestions include exhibitions of BGI examples, including drawings, photographs and site or building models or displays that can be used to help raise awareness (and possible benefits) of potential BGI approaches.
3. Website, social media and local press releases: A project website and Twitter and Facebook accounts will be set up, replaying project updates and circulating news from other relevant research projects in English and Vietnamese. Project meetings in Can Tho will be covered by local media to raise the profile of the UK-Vietnamese research collaboration.
4. Student projects at Can Tho University in WP3 to build capacity for future ecosystem service assessments;
5. Attendance of workshops and conferences by all members of the project team to raise the project profile;
6. Synthesis scientific report, Policy Brief / Fact Sheet and academic publications: Policy Briefs / Fact Sheets will be produced in English and Vietnamese under guidance of the AB and made available online and in print. Further, an in-depth technical synthesis report will be launched at the final meeting and published on the project website. At least five peer-reviewed academic paper will be published in academic papers in high-impact journals, reflecting the multi-disciplinary nature of the project.

| Description | WP1: Stakeholder Engagement Management Plan developed and approved. The stakeholder mapping exercise adopted a layered approach for categorising key stakeholders (i.e. by geospatial reach, specific roles/policy, power/influence). This work included identification and inclusion of key stakeholders that may otherwise have been overlooked. Accordingly, suitable engagement mechanisms and time frames were proposed for effectively working with stakeholders (using the most relevant methods for specific types of stakeholders and considering the limitations posed by Covid-19 travel restrictions). Deliverables submitted to NAFOSTED include D1.1 "Stakeholder Engagement Mapping Report" (March 2020) and D1.2 "Report of existing and potential BGI measures for Can Tho" (Sept 2020). WP2: The High-Performance Integrated hydrodynamic Modelling System (HiPIMS) has been further developed and set up for multi-scale flood modelling in Mekong River Basin. The improved HiPIMS has been used to reproduce an extreme flood event in 2011 and validated against the inundation extent extracted from remote sensing imagery. On a smaller scale, a 1D model based on MIKE 11 has been successfully implemented by Can Tho University and integrated with the 2D HiPIMS model to reproduce/predict fluvial flooding from Hau River and Can Tho River. Subsequently, city-wise flood risk assessment has been carried out to identify the 'hotspots' of flooding. A focus case study is selected from the identified 'hotspots' to perform high-resolution simulations to better understand the impact of different BGI strategies on flooding dynamics and risk. For this purpose, HiPIMS has been further developed to directly model different BGI measures and their influence on flood propagation and flood risk. Further modelling components have also been developed and coupled to HiPIMS to simulate the full-process dynamics of point-source, and non-point-source pollutants, from pollutant wash off, transport to deposition, driven by urban overland flows and flood waves. The key deliverables of WP2 include 3 refereed journal papers and two reports submitted to NAFOSTED, i.e. D2.3 "Develop a new integrated flood model for Mekong Delta and Can Tho" (Apr 2020) and D2.4 "Flood modelling of BGI scenarios in Can Tho city" (Dec 2020). WP3: A conceptual model and types of BGI within the city of Can Tho with regard to Natural Capital and shared as a report to NAFOSTED. Further work was then done on the spatial locations of different types of BGI within the city and also the potential ecosystem services that may arise from them and how these effects relate in a spatial way. Research on investigating the spatial impacts of BGI ecosystem services through using data collected from workshops and remote sensing and using GIS to conduct spatial analysis. Unfortunately due to Covid and logistics the monitoring components in the field in Can Tho was not possible WP4: Fieldwork in Vietnam has been completed. In particular, a household survey with N=772 was successfully conducted by the Vietnamese team. Survey data was analysed and a research paper published. Results indicated that flood control is the most highly valued ecosystem service, followed by recreation and biodiversity. Household willingness to pay for flood control-related benefits is higher than the willingness to pay for other ecosystem services and disservices. Results further suggest that overlooking the existence of ecosystem disservices generated by the installation of blue/green infrastructure measures, such as sponge parks, could lead to the overestimation of welfare effects. |
| Exploitation Route | WP1: Stakeholder Engagement Management Plan developed and approved. Through the work completed as summarised in Deliverables D1.1 "Stakeholder Engagement Mapping Report" (March 2020) and D1.2 "Report of existing and potential BGI measures for Can Tho" (Sept 2020) we now have a much richer understanding of the complex mix of stakeholders that are, and should be, involved in decision making about BGI measures in Can Tho, but also for consideration in other Vietnamese contexts. Although the concept of BGI is still new in Can Tho and has not yet been institutionalized, some of BGI's principles have been applied in a number of projects in Can Tho. Most BGI measures (or similar) in Can Tho were not designed purely based on BGI principles with few exceptions such as such as water retention lakes built as part of the World Bank project, the Rach Ngong Park and the constructed wetland inside Can Tho University. The majority of these BGI-type measures in Can Tho are green areas inside public parks, along walking paths next to main rivers and canals and along some main roads. A comprehensive list of existing BGI-type measures were identified during a consultation workshop organized in March 2020 with relevant local stakeholders in Can Tho and are provided in D1.3. WP2: The High-Performance Integrated hydrodynamic Modelling System (HiPIMS) has been further developed and set up for multi-scale flood modelling in Mekong River Basin. HiPIMS has been further developed to directly model different BGI measures and their influence on flood propagation and flood risk. Further modelling components have also been developed and coupled to HiPIMS to simulate the full-process dynamics of point-source, and non-point-source pollutants, from pollutant wash off, transport to deposition, driven by urban overland flows and flood waves. The benefit of BGI in mitigating flood risk and improving urban water quality is now better understood for the Can Tho context. WP3: A conceptual model and types of BGI within the city of Can Tho with regard to Natural Capital. Further work was then done on the spatial locations of different types of BGI within the city and also the potential ecosystem services that may arise from them and how these effects relate in a spatial way. Research on investigating the spatial impacts of BGI ecosystem services through using data collected from workshops and remote sensing and using GIS to conduct spatial analysis. A second report for NAFOSTED was produced on this component of WP3. Drafting of a journal publication on the application of the Natural Capital approach to BGI in urban areas continues. Unfortunately due to Covid and logistics the monitoring components in the field in Can Tho was not possible WP4: Fieldwork in Vietnam has been completed. In particular, a household survey with N=772 has been successfully conducted by the Vietnamese team. The study examined public preferences for developing sponge parks using blue/green infrastructure in Can Tho city. Particularly, the work assesses the economic value associated with the provision of a set of ecosystem services (flood control, recreational activities, biodiversity) and ecosystem disservices (pest abundance) provided by blue/green infrastructure using a discrete choice experiment. Results indicated that flood control is the most highly valued ecosystem service, followed by recreation and biodiversity. Household willingness to pay for flood control-related benefits is higher than the willingness to pay for other ecosystem services and disservices. Results further suggest that overlooking the existence of ecosystem disservices generated by the installation of blue/green infrastructure measures, such as sponge parks, could lead to the overestimation of welfare effects. This is the first study to account for the value of potential ecosystem disservices associated with blue/green infrastructure in the context of developing countries. It is suggested that these policies should be designed in a way to strengthen cities' resilience and deliver the conditions needed to improve human wellbeing, while minimising the effects of welfare-reducing elements. Future research conducting environmental valuation studies should integrate both ecosystem services and disservices in order to generate policy recommendations that improve local communities' wellbeing. |

| Description | - An initial workshop was held in Can Tho, in June 2020 for 21 participants that represented a broad range of stakeholders. The workshop provided insights into what flood modelling information and research outputs the various stakeholders would find most useful in helping them to make informed decisions about BGI locations and potential effectiveness. The workshop demonstrated good levels of interest from stakeholders in better understanding the role of BGI measures. This project has provided an important platform for some follow on funding from NERC (see associated 'Further funding' section); for both projects members of the ValBGI team were Co-Is for projects that were led by two Early Career Researchers (namely Dr Majoribanks and Dr Chen). Note: Unfortunately, the travel restrictions associated with Covid-19 put large constraints on the project and the project's impact particularly, the valuation survey in WP4 that was completed in February 2021, albeit approximately 10 months late. Fieldwork for the ecosystem service measurements in WP3 could not be completed (or even started), largely due to an inability to procure, deliver and set up monitoring equipment in Can Tho. |

| PI Contribution | An additional £39,978 of funding was obtained for an integration project linking ValBGI to another UK-Vietnamese project ("DroughtFlood" NE/S002847/1) in the same programme. The tasks to be completed in this integration project are joint activities, so cannot be separated between our contributions and partner contributions. The five tasks are: Task 1 (DroughtFlood WP3&5 + ValBGI WP2): Link hydraulic modelling and applications for the rural VMD (in DroughtFlood) and Can Tho (in ValBGI) to provide more accurate integrated boundary conditions of riverine flooding to predict the impact of surface water flooding in rural and urban settings and to quantify one type of positive externality of interventions upstream. Task 2 (DroughtFlood WP1 + ValBGI WP1): Assess the perception of stakeholders as to the existence and potential of ecosystem benefits of flood control beyond increases of flood resilience. While already a core part of the stakeholder work in ValBGI WP1, the role of ES (i.e. natural capital) can readily be explored in the stakeholder workshops planned in DroughtFlood. We will develop a common framework of ES links between rural and urban areas of the VMD and assist stakeholders in producing a conceptual diagram of all ES in the agricultural area which are impacted by controlled ingress of floodwater into agricultural plots as an additional component of the SDM. Task 3 (DroughtFlood WP2&3 + ValBGI WP3): Assess and quantify relevant ES at multiple sites in rural and urban areas using land-use maps based on earth observation. This task will link ES provision to existing data (in DroughtFlood) on land systems and livelihoods in the upstream areas. Task 4 (DroughtFlood WP2&3 + ValBGI WP4): Assess the (economic) value of (T4.1) increased flood resilience downstream resulting from implementation of measures upstream and (T4.2) of additional ecosystem benefits in the upstream rural area. T4.1 can be valued by an addition to the valuation survey planned within ValBGI WP4 (to assess the willingness of Can Tho residents to pay to support flood resilience measures upstream), whereas T4.2 is valued using benefits transfer by means of the ARIES tool (http://aries.integratedmodelling.org/). Task 5 (DroughtFlood WP1&5 + ValBGI WP1): Feed the acknowledgement of the interprovincial links in terms of provision of flood resilience and additional ecosystem benefits back to the stakeholders in both projects. The aim is to scope the barriers to the implementation of an integrated, delta-wide (and hence interprovincial) flood management strategy that makes explicit the externalities between upstream and downstream areas. |

T4.1 can be valued by an addition to the valuation survey planned within ValBGI WP4 (to assess the willingness of Can Tho residents to pay to support flood resilience measures upstream), whereas T4.2 is valued using benefits transfer by means of the ARIES tool (http://aries.integratedmodelling.org/). Task 5 (DroughtFlood WP1&5 + ValBGI WP1): Feed the acknowledgement of the interprovincial links in terms of provision of flood resilience and additional ecosystem benefits back to the stakeholders in both projects. The aim is to scope the barriers to the implementation of an integrated, delta-wide (and hence interprovincial) flood management strategy that makes explicit the externalities between upstream and downstream areas. |
