in addition, the implementation of social justice and educational lu approaches, especially for women and children, are also contributing to the success an of the enactment of the Millennium Development Goals (MDG) va n The development status of the Island, the isolation characteristic, the to tn distance between neighboring islands, between islands and the mainland, the ie gh change of the environment, climate change, changes in rainfall, etc are the p challenges of water resources management The Island, located in the lower floor of oa nl w the Southwestern area, is a vulnerable area to climate change and sea level rise Furthermore, the island is affected by the early phase of the El Nino and La Ninas d The Island is a key economic zone with typical activities, such as: fishing, oil and a lu countries in the region nf a nv gas exploitation, maritime services, tourism as well as it is adjacent to the other oi lm ul Especially, Phu Quoc Island is the largest island in the coastal island system in Vietnam The current status of the economic development has created a at nh significant social pressure on the island regarding both system resources and the z environmental management There is no rational planning and efficient use of z @ natural resources, although the extraction (water, oil, gas ) has been carried out for gm a long time Therefore, freshwater resources in Phu Quoc Island are vitally om l.c important, and have a direct impact on daily life, and the development of the island The assessment of freshwater resource vulnerability in Vietnam is still very limited, an Lu particularly in the Island A vulnerability assessment of freshwater resources in Phu n va ac th si Quoc Island will be essential to identify potential risks for fresh water resources on the island and to support decision making; Therefore, detecting early threats to gain insight sustainable solutions to the management of freshwater resources on an island, where the exploitation of freshwater resources management is still problematic Understanding the vulnerability of freshwater resources of the Islands, therefore, is important to ensure sustainable water management in the region Uses of water have an intimate relationship with land use and impact on ecosystems dealing with integrated water resource management The integrated water resources lu an management will help to use and to protect natural resources In order to effectively va implement integrated water resource management, the necessity of understanding n to and the ability to assess the vulnerability of water resources are highlighted tn Performing a vulnerability assessment of freshwater will highlight gaps in gh p ie information and identify the most influential factors affecting vulnerability, in addition to raising public awareness The availability of such an evaluation would oa nl w provide decision-makers with the option to evaluate and modify existing policies and to implement measures to improve the management of water resources d a lu Different approaches to vulnerability assessment of water resources and a nv hydrological systems have been developed for a long time with both advantages and ul nf disadvantages One of the most effective responses, vulnerability assessment has oi lm recently been developed by the United Nations Environment Program and by Packing University This approach is based on the available resources to meet the nh at production, use, environmental pressures mitigation and capacity development and z management It highlights the vulnerability factors such as climate change, z gm @ population growth, economic development, and management, etc of vulnerable freshwater resources Currently, this method is implemented in the Pacific Islands, om l.c in West and South Asia, in the Mekong River basin, and in several other river basins in Vietnam However, the vulnerability assessment of freshwater resources Lu an on islands in Vietnam is very limited and this method is still not an application n va ac th si option Hence, this study can be considered as a the first application of this approach assessing freshwater vulnerability on islands in Vietnam 1.2 Objectives and Research questions 1.2.1 Objective of study The main objectives of the study include: - Piloting a method in terms of assessing the freshwater vulnerability in the southwestern area of Vietnams: applied specifically on Phu Quoc – Kien Giang Province; - Assessing vulnerability of freshwater resources on the Island of Phu Quoc – lu Kien Giang and potential agents; an - Providing scientifically-based evidence to support policy development of water va n resources management, to support the decision-making process; to tn - Proposing measures to reduce the vulnerability of freshwater resources on the ie gh Phu Quoc Island p 1.2.2 Research questions - What methods and tools are appropriate to assess the vulnerability of oa nl w freshwater resources on the Island? d - Which elements are vulnerable to freshwater resources? a nv a lu - What are the opportunities and challenges regarding to freshwater resources management in the Island? nf the Island? oi lm ul - What are solutions that should be done to improve the freshwater resources in at nh 1.3 The Assessment Process Water is essential for life All activities of humans, animals and plants on z earth need water However, freshwater resources are vulnerable and a reliable z @ assessment of vulnerability is essential The vulnerability assessment of freshwater gm resources, newly developed by UNEP (United Nations Environment Program) and om l.c by Peking University is the methodology of the thesis Firstly, relevant data in the study area are collected, including: relevant documents such as natural conditions, Lu an hydrology, environment, geology, etc The statistical analysis results are collected n va ac th si directly from the local agencies The data processing is necessary to investigate additional fieldwork and to update the latest data content research serving as the current status and characteristics of water resources on the island and the control system influence of the current vulnerability of freshwater resources This study will provide an overview of the evaluation method to assess the vulnerability of water resources; the preferred method will be the approach developed by UNEP (United Nations Environment Program) and Packing University The evaluation of data will serve an analytical framework DPSIR (Driver, pressure, state, impact and response) to analyze quantitative and qualitative features, and a description of the lu an vulnerability of freshwater resources on the island Then, an integrated vulnerability va index (VI) is calculated based on possible vulnerable parameters; the results will n to assess the vulnerability of freshwater resources on the island, followed by a tn proposal for solutions to reduce the vulnerability of freshwater resources on the Phu gh p ie Quoc Island 1.4 Structure of the thesis This report is divided into six chapters The first chapter introduces the oa nl w research to answer three main questions: Why is a vulnerability assessment is d important? How can we assess the vulnerability of the island? And, what are the a lu a nv main objectives of a vulnerability assessment in this study? ul nf The chapter two reviews several studies about the concept of vulnerability, oi lm vulnerability

encompass more than 25 different definitions, concepts and methods to systematize vulnerability (for example, Chambers, 1989; Bohle, 2001; Wisner et al., 2004; Downing et al., 2006; UN/ISDR, 2004; Pelling, 2003; Luers, 2005; Green, 2004; UN-Habitat, 2003; Schneiderbauer and Ehrlich, 2004; van Dillen, 2004; Turner et al., 2003; Cardona, lu 2004b) According to Downing (2006), the vulnerability includes the expression, an sensitivity and resilience of the system to combat the dangers posed by the effects of va n the agent Researchers in the field of natural sciences often focus on the concept of to tn risk, while researchers in the field of social sciences often refer to the term ie gh vulnerability Concept of vulnerability is the social scientists associated with the p group of socioeconomic factors and the community's ability to cope with natural oa nl w disasters, but scientists about climate usually consider the concept of vulnerability as a function of the likelihood of occurrence and the potential impact of weather and d climate related a lu a nv According to Jörn Birkmann (2006) statistics, one of the best-known nf definitions were formulated by the International Strategy for Disaster Reduction oi lm ul (UN/ISDR), which defines vulnerability as: - The conditions determined by physical, social, economic and environmental z of hazards (UN/ISDR, 2004) at nh factors or processes, which increase the susceptibility of a community to the impact z @ - In contrast, the United National Development Programme (UNDP) defines gm vulnerability as: a human condition or process resulting from physical, social, om l.c economic and environmental factors, which determine the likelihood and scale of damage from the impact of a given hazard (UNDP, 2004: 11) an Lu n va

water resources of the Island, combined with the limited industrial development on the Island is sufficient to provide mixing and dilution of currently wastewaters discharge However, with the development of the Island, the parameters are very vulnerable The lack of minimum infrastructure to treat waste water and solid waste from domestic and fish processing sources, leading to serious pollutions (for lu an instance, in Vung Bau and Cua Can) This will affect ecosystems, forest protection, the va quality of human life would not be guaranteed With IWRM Capacity (MC = 0,642) is n tn to assessed by three parameters Includes: Conflict management capacity parameter gh (MCi), Improved sanitation inaccessibility parameter (MCs), Water Use Efficiency p ie Parameter (MCe) These parameters are large, it represents the IWRM capacity is a oa nl w major problem on the Phu Quoc Island On the Island there isn't perform sharing, allocation of water resources In the d future, when the demand for water will increase raises the contradiction, conflicts Therefore, it is necessary to study in order to solve the problem sharing, allocation of water resources between sectors, between the upstream and downstream of the river nv a lu an ll fu Moreover, the uneven distribution of rainfall between the months of the year and change of terrain on the Island will lead to water scarcity during dry season.Due to rapid expansion of tourist activities on the Island also causes increased water demand With the poor on human resources for water resources management will lead to the bad management results In addition, the sea water level rise, saltwater instruction, changing on frequency and intensity of natural disasters such as storm will all pressure m tz a nh oi z gm @ Phu Quoc„s
