“…This stakeholder approach was also chosen to increase flood awareness, and the Vietnamese participants did indeed report to the involved Dutch experts that they have gained knowledge on these topics. However, we have not systematically measured the learning effect, as has been done by Arciniegas et al (2011). The topic of climate change has gained importance in HCMC.…”

“…The right of the population to participate in local government affairs through the People's Committee is formalized in the Grassroots Democracy Decree of 1998 (Duong, 2004), which was updated in 2003 and 2007. An interactive approach was applied using a Touch Table (Arciniegas et al, 2011), drawing on large maps, and other tools, with emphasis on creation by the stakeholders, and facilitation by Dutch experts, ensuring that the outcomes of the workshops represented the visions of the participants, which should assure acceptability. Five flood management strategies were developed: (S1) a strategy protecting the district with levees, hence aiming at reducing flood probability; strategies aiming to reduce flood exposure and sensitivity by (S2) wet-, and (S3) dry-proofing buildings; (S4) elevating roads and buildings, aiming to reduce flood exposure; and (S5) a combination of several measures (referred to as "CAS") to reduce flood risk with adjusted land use, which additionally would increase the spatial quality of District 4.…”

Abstract. Coastal cities are vulnerable to flooding, and flood risk to coastal cities will increase due to sea-level rise. Moreover, Asian cities in particular are subject to considerable population growth and associated urban developments, increasing this risk even more. Empirical data on vulnerability and the cost and benefits of flood risk reduction measures are therefore paramount for sustainable development of these cities. This paper presents an approach to explore the impacts of sea-level rise and socio-economic developments on flood risk for the flood-prone District 4 in Ho Chi Minh City, Vietnam, and to develop and evaluate the effects of different adaptation strategies (new levees, dry-and wet proofing of buildings and elevating roads and buildings).A flood damage model was developed to simulate current and future flood risk using the results from a household survey to establish stage-damage curves for residential buildings. The model has been used to assess the effects of several participatory developed adaptation strategies to reduce flood risk, expressed in expected annual damage (EAD). Adaptation strategies were evaluated assuming combinations of both sea-level scenarios and land-use scenarios. Together with information on costs of these strategies, we calculated the benefit-cost ratio and net present value for the adaptation strategies until 2100, taking into account depreciation rates of 2.5 % and 5 %.The results of this modelling study indicate that the current flood risk in District 4 is USD 0.31 million per year, increasing up to USD 0.78 million per year in 2100. The net present value and benefit-cost ratios using a discount rate of 5 % range from USD −107 to −1.5 million, and from 0.086 to 0.796 for the different strategies. Using a discount rate of 2.5 % leads to an increase in both net present value and benefit-cost ratio. The adaptation strategies wet-proofing and dry-proofing generate the best results using these economic indicators. The information on different strategies will be used by the government of Ho Chi Minh City to determine a new flood protection strategy. Future research should focus on gathering empirical data right after a flood on the occurring damage, as this appears to be the most uncertain factor in the risk assessment.

“…Fitzimons et al (2012) and Arciniegas et al (2011) incorporate the preferences of the agents over spatial definitions of predefined criteria, in most cases with satellite data and expert opinion. Strager and Rosenberg (2006) also discussed the same problem in the Cacapon River watershed, Virginia, identifying the preferences before defining the maps with GIS.…”

ABSTRACT:Multi-criteria analysis in collaborative decision making can provide a useful tool to improve the governance in protected areas with strong conflicts between stakeholders. This paper offers an in-depth review about MCDM methods in protected areas. The analysis considers the topics Land Use, Management, Species, and Zoning and it is based in two dimensions: Methods and Participation. Topics and MCDM methods and Topics and Participation were significantly related and contrasted using a Chisquared test, respectively. We have identified two groups by topics: Zoning and Species use continuous non participative methods and Land Use and Management use discrete methods with increasing participation. KEYWORDS:Collaborative Decision-Making, Multi-criteria analysis, protected areas. Una revisión crítica de la toma de decisiones multi-criterio en áreas protegidas RESUMEN:El análisis multi-criterio para toma de decisiones colaborativa ofrece una herramienta útil para mejorar la gobernanza en áreas protegidas, con fuertes conflictos de intereses entre agentes. Este artículo ofrece una revisión en profundidad sobre métodos MCDM en áreas protegidas. El análisis considera los temas Uso de la tierra, Gestión, Especies y Zonificación, y se basa en dos dimensiones: Mé-todos y Participación. Los Temas y las Técnicas MCDM y los Temas y la Participación están significativamente correlacionados respectivamente según un test Chi-cuadrado. Hemos identificado dos grupos: Especies y Zonificación usan métodos continuos no participativos y Uso de la tierra y Gestión, utilizan métodos discretos donde la participación es creciente. PALABRAS CLAVE:Análisis multi-criterio, áreas protegidas, toma de decisiones colaborativa.

“…Based on mathematics and statistics, these models tried to incorporate spatial variables in multiple regression models or as land-use conversion probabilities in transition probability matrices. With the progress of computer technology, and especially after the introduction of geographical information systems (GIS), land-use allocation and optimization modelling became more wide-spread [17][18][19][20][21][22]. Land-use optimization models typically involve the optimization of the size as well as the spatial pattern of land use [23].…”

A Spatial Optimization Model for Sustainable Land Use at Regional Level in China: A Case Study for Poyang Lake Region

et al. 2014

Economic growth in China is accompanied by many problems, such as rapid deterioration of the environment and a sharp decline in the area of arable land. China's current land-use planning system fails to deal with these problems, especially at the regional level. The lack of sustainable spatial allocation at regional level has become a pressing problem. This article aims to: (1) analyze the reason why sustainable land use at the regional level is difficult to achieve under the current Chinese land-use planning system; (2) put forward a regional optimization model for sustainable land use; and (3) explore the usefulness and possibility of the future application of the model in supporting land-use planning. The model has been applied in a case study for the Poyang Lake Region, Jiangxi Province in China. Based on predictions of the demand of land in 2015, three single-objective scenarios were constructed: food production oriented, nature conservation oriented and economic growth oriented. An optimized, multi-objective pattern of sustainable land use was achieved by integrating the three single-objective scenarios. The relevance and applicability of the model were discussed with planning experts and practitioners. The results indicate that the model can contribute to a more sustainable regional land-use planning in China. However, the results also show a need for further research on how to embed wider social and economic aspects in the model. OPEN ACCESSSustainability 2015, 7 36
