INTRODUCTION This vulnerability assessment follows a toolkit based on the experience of a Participatory Climate Change Vulnerability and Adaptation Assessment of Sorsogon City, Philippines. This is a participatory process of selected stakeholders which builds citizens’ capability to address city vulnerability to climate change scenarios and to develop adaptation strategies. Some of the steps in the original methodology have been modified to suit the local situation of the Negombo Municipal Council (NMC) area. The main objective of this vulnerability assessment is to estimate the local area vulnerability to potential climate change impacts and provide a context for local government decision makers to develop local climate change adaptation and mitigation plans in response to the Sorsogon City Vulnerability Assessment and Adaptation (V&AA) results. This study follows the same concept definitions adopted in the Sorsogon City V&AA report. Interpretations of key concepts are mentioned below for reference purposes. Climate Change refers to any change in climate over time, whether due to natural variability or because of human activity. Vulnerability is the degree to which a system is susceptible to, or unable to cope with, adverse effects of climate change, including climate variability and extremes. Vulnerability is a function of the character, magnitude, and rate of climate variation to which a system is exposed, its sensitivity, and its adaptive capacity. Adaptation is an adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm of exploits beneficial opportunities (Third Assessment Report, Working Group II) Exposure is what is at risk from climate change (e.g. population, resources, property) and the change in climate itself (e.g. sea level rise, temperature, precipitation, extreme events). Sensitivity is the biophysical effect (e.g. flooding, strong winds, land inundation, etc) of climate change which also considers the socioeconomic context of the system being assessed. Adaptive Capacity is the ability of a system to adjust to climate change (including climate variability and extremes) to moderate potential damages, to take advantage of opportunities, or to cope with the consequences. The IPCC Third Assessment Report outlines that it is a function of wealth, technology, institutions, information, infrastructure, and ’social capital’. 4 | P a g e Negombo, Sri Lanka: Climate Change Vulnerability Assessment This report explains the overall process flow of a Participatory Vulnerability Assessment with a description of each step and respective findings. Some of these initial steps which were briefly described in the inception report have been modified during this process.

PHASE ONE MOBILIZATION This phase is a pre-assessment stage to establish the assessment process. The process aims to influence local stakeholders, to obtain their acceptance and their willingness to participate in the development of local response actions. Phase One – Mobilization Step: 1 Step: 2 Step: 3 Step: 4 Step: 5 Brief L/As Mobilize Field Agree on Stakeholder and DSD on assessment reconnaissance assessment Mapping Climate team survey purpose and Change scope There are five key steps in this phase are described in the following section. 2.1. Step: 01 Brief Local Authority (L/A) and Divisional Secretariat Division (DSD) on Climate Change This step introduced the project to the city’s key decision makers. The main objectives of this project are: 1. To give an overview of the vulnerability of cities to climate change. 2. To describe the importance of a vulnerability assessment in a sustainable city development process. 3. To recognize the views of stakeholders regarding vulnerable groups in the local area. 4. To develop a partnership (to ensure the support and commitment of stakeholders to succeed in the above task) between stakeholders and the project team through mutual understanding and interaction. This was the first time that Sri Lankan local authorities took part in conducting a city-level climate change study. It required a strong foundation to identify and reconcile the aims and objectives, nature, expected contributions and usefulness of this project. Accordingly, the two key administrative bodies of the local authority: Negombo Municipal Council (NMC) and Negombo Secretariat Division (NSD) were selected for the initial discussions. 6 | P a g e Negombo, Sri Lanka: Climate Change Vulnerability Assessment The key objectives and a brief explanation were given for each objective below. a. Climate change is a key concern of the Sri Lankan government and there have been a number of actions taken to address the impacts of climate change for the country. - The United Nations Framework Convention on Climate Change (UNFCCC) was adopted at the Rio summit in 1992 and the Government of Sri Lanka ratified the UNFCCC on the 23rd of November, 1993. In order to achieve the objectives of the UNFCCC, a binding protocol was adopted at the 3rd Conference of Parties (CoP 3) by the UNFCCC held in Kyoto, Japan in 1997 and Sri Lanka acceded to the Kyoto Protocol on the 3rd of September, 2002. - The Ministry of Environment and Natural Resources is the national focal point of the UNFCCC, and has the responsibility of implementing the provisions in the Convention and to take the initiative to pursue the decisions made at sessions of the COP and its subsidiary bodies. The Ministry of Environment and Natural Resources and the UNFCCC have established a Climate Change Secretariat and a Climate
