Ecosystem-based adaptation to increase flood resilience of vulnerable people – Evidence from central Vietnam
Introduction
Floods are amongst the most devastating natural disasters, especially in Asia. Sea-level rise, changing rainfall patterns due to climate change as well as rapid urbanization result in increased flood risks at Asia’s coasts and inland areas. Developing countries are especially vulnerable to floods due to their limited capacity to prevent and absorb disaster effects. Furthermore, within developing countries the poorest people are often the most vulnerable, as they live in the most threatened locations and struggle to adapt due to income constraints. Women present another vulnerable group, because they commonly experience disadvantages in social, cultural, economic and political domains as well as legal status and opportunities. These socio-cultural circumstances lead to increased deaths among women during floods, and higher poverty rates due to more unemployment and a lack of basic rights. Moreover, women face more psychological stress during and after a disaster due to the women’s caretaker role. To limit the impacts of floods, ‘structural measures’, such as dikes or reservoirs, are the main focus of flood management in many regions within Asia, including Vietnam. However, these measures are often associated with negative impacts on the environment, on which especially poor and vulnerable communities depend on. A useful and complementary approach is Ecosystem-based Adaptation (EbA). EbA is a more inclusive approach that takes into consideration vulnerable groups, whose livelihoods directly depend on natural resources, and make it a possible means to strengthen their position by offering multiple benefits. These measures also seem promising to help achieve Sustainable Development Goals (SDGs) 5 (Gender equality), 10 (Reduced inequalities) and 13 (Climate Action).
Implications
EbA is a possible means to adapt to climate change and can reduce the risk of disasters while simultaneously improving the flood resilience of those that are especially vulnerable to the impacts. Analyses focusing on the role of women and the poor in EbA measures implemented in Central Vietnam, such as the restoration of urban ponds and mangroves, provide an evidence in favor. Lower income households as well as women, in both urban and coastal areas, hold higher values for the changes that occur due to these measures, which not only reduce the risk of climate change impacts, but also present (new) livelihood opportunities and income security. It is therefore recommended to consider complementing structural measures such as dikes or reservoirs with EbA measures, and look into locations where EbA measures can replace hard measures altogether.
The project
In addition to this policy brief, the ResilNam project will complement these findings by also making further recommendations regarding:
- The gender gap in flood resilience across the province;
- The possible well-being impacts of flooding (across genders);
- Gender dynamics in disaster risk management;
- Community level adaptation projects.
The policy recommendations across all of the ResilNam activities can help increase flood resilience of urban and coastal communities in Thua Thien-Hue Province. Additionally, the ResilNam directly invests in ecosystem-based adaptation measures in collaboration with local stakeholders to increase flood resilience and strengthen the role of women in disaster risk management.
The project is part of the Global Resilience Partnership Water Window and it is implemented by the University of Potsdam, the Centre for Social Research and Development and the Institute for Environmental Studies/VU University Amsterdam.
Via the gender sub-samples we find that women have higher WTP values for all the ecosystem services, except for changes in tourism in Hue City, where WTP values are more or less the same (see Figures 4 and 5). An increase in protection from storms and floods not only protects women and their family’s lives during a flood, but also means that the work that needs to be done during the flood itself and the aftermath is reduced. Positive changes in seafood abundance and recreation suitability mean a more secure and pleasant environment for their household. The development of tourism provides interesting opportunities for women to increase and stabilize their income, especially in the rural areas where little other job opportunities arise.
