Outline
Assessment from 1995 – 2003 in Giao Thuy, a coastal district in the north of Vietnam,
Discussion on the limitations and dissatisfactions on the findings,
On-going development of a new approach.
Giao Thuy – social vulnerability ? Objectives
to assess social vulnerability and resilience under the effects of
economic renovation and the implications for local society
coping with the impacts of climate and weather extremes.

Aquaculture
Why Giao Thuy? is selected on the basis of statistical
and social representativeness that provides a typical account of the social structure is a resource-dependent community
affected significantly by institutional changes.
annual climate and weather extremes are given special considerations in local policy making.
impacts of institutional changes under economic renovation and climatic related events have altered the social structure and local adaptive capacity.
allows a theoretical, analytical and descriptive basis to obtain a high level of insights and thoroughness.
Questions asked!
What are the changes of local society under the effects of economic renovation and consequences from these changes? And how is the local society responding to the consequences?
What are the impacts of climate and weather extremes on social livelihoods? And how are these livelihoods recovering from the impacts?
How is the level of social vulnerability and resilience revealed and varied since the economic renovation?
How effective are the chosen indicators in addressing understanding the processes that influence level of vulnerability?

But who benefits from that growth?
Migration as a newly introduced livelihoods
Formal – Governmental Organised Migration and Resettlement programmes
North-North resettlement programme – New Economic Zone, Post-war Migration and Resettlement (1975-1990s)
Population redistribution policies involving both deurbanisation and resettlement in NEZs - North-South migration,
Informal Spontaneous migration (both North-North and North-South), Population growth, land limitation, Employment opportunity, Social networks and structures.
Effects of migration on the social structure Changing gender roles - women more responsible to manage
agricultural land. Some loss of skills in agricultural workforce. Weakening family structure because older members of the family
are absent. Loss of social capital as members of community are absent. BUT increase remittance income.

Aquaculture and migration
Aquacultural development means the rich become richer and the poor become relatively poorer.
The community as the whole does become richer because of aquaculture but the important point is who benefits?
The trend toward inequality amplifies the pressure on poorer households caused by population growth / land limitation, the rising cost of living and other factors such as loss of jobs caused by agricultural mechanisation.
The response of many households is spontaneous migration, only possible since the start of the economic renovation.

Local access to natural resources before and after Doi Moi and Ramsar designation
Before After (2001-2003) Effects Ramsar management
N/A 6000 ha is under strict protection
Limited access decrease the number of locals who totally depend on mangrove
Increase inequality in whole community which shrimp pond owners gain
Policies on use and access to the natural resources
Free access to the mangrove in the area. No regulations to control the exploitation of the area.
Water resources and soil quality control
Maintain natural balance and the ecosystem,
Protection forest Production forest
Increase social resilience by higher productivity and stability of rice production.
Loss of resilience by limited employment, loss of skills and changes in social structure due to changes in labour allocation and new trends, such as spontaneous migrations.

Effects of migration and changes in labour force on the level of social vulnerability
Remittance income has a complex and often opposing effects on the resilience of the poorer members of the community.
Limit the loss of resilience caused by aquaculture development and other trends but it is not enhancing resilience by diversifying livelihoods in the local community - it is being invested in existing agricultural activities.
Because of effects on gender roles, skills in the agricultural workforce, etc, it has negative effects on resilience.
However, migration livelihoods are less dependent on the environment, there is increased resilience to current environmental stress and long-term global environmental change compared to local livelihoods such as agriculture and fishing.
It is important to separate out these different effects rather than simply saying migration or aquaculture is good or bad.
Climate extremes and local response
examine the aquacultural, non-aquacultural, migrant and non-migrant communities coped with typhoon strikes,
cover the income from different sources at household level, loss caused by the extremes, reinvestment (recovering expenses) and the workforce available and involved to recover from the extreme events.
most recent and serious typhoon strikes occurred in the region in 1992, 1996 and 1998.

Implications from testing indicators
1. Changes in institutions have had good effects on both agriculture and aquaculture, the implications showed an increase in the level of social resilience in both the aquaculture and the non-aquaculture groups.
2. Testing financial and inequality indicators showed that the whole community got better off reduce social vulnerability but pressures on the rest of the population. Non-aquacultural groups still face a loss of social resilience caused by the development of aquaculture.
3. Two different trends, labour reallocation and spontaneous migration, both closely related to each other. Migration, with remittance income, has limited the loss of resilience but it is not improving coping capacity by diversifying livelihoods in the local community as remittance income is simply being invested in traditional activities or saved. Migration caused loss of skills in the rural society and changed the gender role on agricultural works, leading to further loss of social resilience.
4. Coping with the extreme events, typhoon strikes. Aquacultural community remains most sensitive and dependent economic sector but adaptability has enhanced considerably by the improved financial and human capacities. Non-aquaculture group, though less dependent on the environment than aquaculture, but is the most vulnerable to the climate and weather extremes.

Implications from testing indicators
Limitations and dissatisfactions Communication skills
the ability to ask relevant questions open to the knowledge and competence of the local community and
are prepared to admit their own ignorance of the local situation the researchers and the local community have to be prepared to
give up their preconceived ideas interpretation / translation
Power issues information provided by different members of the local community,
depending on their positions in the society can reflect their own view of the subject under discussion
Gender issues Gender differences define how, in a specific social and cultural
context, women and men interact and what is considered appropriate for each to do, thus determining their development options and constraints
Location and time Information is gathered from the perspective of the inhabitants
of one village while other groups of other locations and their perspectives are excluded, especially if different ethnic groups or even in different countries are concerned.
Superficial data stop at describing the activities and physical surroundings of a
community and often fail to investigate deeper to understand strategic decisions that underlie the observed patterns of activities or to see how these strategies have evolved over time
Uncertain quality of data Principles of crosschecking information by seeking different
sources and using different methods to obtain information about the same thing are not always undertaken.
Imposition of new concepts Tools and techniques used in the field maybe absolutely alien
to the local community, abuse of these techniques and tools will give wrong, even converse data and information
Extractive and empowering application of the approach Most approaches and techniques tend to extract information,
some empower the local community to obtain data and information. Interactive process is neglected.
Weaknesses in follow-up What can we do for the community afterwards?
Limitations and dissatisfactions (cont.)
Authority Decision making identity
Scientific community
Normally one way, no direct response from the local community. Research tends to explore the fact rather than the local
knowledge in order to use it effectively.
Local community
Very weak and sometimes mistakenly interpreted, local knowledge has not been considered as equally
important to scientific findings.
Decision made tom down to the society with support from scientific community, local
knowledge normally ignored
Weak response, sometimes too late as
decision has been made and implemented
Relatively effective support for decision making process,BUT
not involved local community
Information provision only, facts and figures sometimes
misinterpreted due to bureaucratic process
STRONGER LINK NEEDED
THIS LINK SHOULD INCLUDE LOCAL PARTICIPATION
More questions asked! How to establish an effective, interactive and continuous link
between the local community and the authority, which should include scientific community?
What can be used to give the local community a means to employ their knowledge to assist the authority and scientific community in developing an adaptation strategy which works?
