======  UNESCO's Response to Climate Change in Marine World Heritage Sites ======
 {{ :globalclimatechg.png?200|}}

**Introduction:**

The impacts of climate change on marine ecosystems are profound, threatening the biodiversity, cultural significance, and natural beauty of World Heritage sites.  Recognizing these challenges, UNESCO has taken a multi-faceted approach to address and mitigate climate change effects on marine World Heritage sites. Here's a summary of their initiatives:

| **Actions**                          | **Details**                                                                                                                                                            |
|--------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Monitoring and Assessment**        | UNESCO identifies climate change as the primary threat to marine sites, with 70% at risk. Through ongoing monitoring, including eDNA studies, they assess species vulnerability. |
| **Research and Science**             | In 2021, UNESCO launched a global eDNA project to enhance understanding and conservation of marine species. They also focus on assessing climate impacts on coral reefs, predicting future scenarios. |
| **Capacity Building and Adaptation** | Initiatives like "Resilient Reefs" focus on building climate resilience. The Climate Vulnerability Index (CVI) aids in planning conservation actions by assessing climate impacts. |
| **International Collaboration**      | UNESCO leverages platforms like the G20 for advocacy, introducing conservation innovations like Reef Resilience. They also call for increased scientific investment at UN Climate Change conferences. |
| **Public-Private Partnerships**      | Collaborations with private entities, such as the Global Fund for Coral Reefs, fund and implement climate adaptation measures. |
| **Education and Awareness**           | Programs like the UNESCO Asia Pacific World Heritage Project aim to educate youth on marine biodiversity and climate change. |
| **Policy and Strategy Development**   | UNESCO develops policies and strategies integrating climate action with heritage conservation, influencing global climate strategies. |

By these concerted efforts, UNESCO not only aims to safeguard these invaluable marine heritage sites but also underscores their importance in global biodiversity and climate regulation, ensuring a legacy for future generations.

| **Aspect**                  | **Details**                                                                                                           |
|-----------------------------|-----------------------------------------------------------------------------------------------------------------------|
| **Year Introduced**         | **2019**                                                                                                              |
| **Purpose**                 | To assess the vulnerability of World Heritage sites to climate change impacts, aiding in conservation planning.       |
| **Key Components**          | - **Exposure**: Measures the degree to which a site is exposed to climatic stressors.- **Sensitivity**: Evaluates how sensitive the site's values are to these changes.<br>- **Adaptive Capacity**: Assesses the ability of the site (both natural systems and human communities) to adapt to climate changes. |
| **Process**                 | 1. **Identify Key Values**: Based on the site's Outstanding Universal Value (OUV).<br>2. **Select Climate Stressors**: Choose the three most impactful stressors for the site.<br>3. **Assess Vulnerability**: Through workshops involving local stakeholders.<br>4. **Plan Adaptation**: Formulate strategies based on vulnerability findings. |
| **Application**             | Used in workshops and assessments for various World Heritage sites, focusing on marine sites for climate resilience.  |
| **Outcome**                 | Provides a vulnerability score that helps prioritize conservation and management actions, informing policy and funding decisions. |
| **Benefits**                | - Enhances understanding of site-specific climate risks.<br>- Facilitates targeted conservation efforts.<br>- Promotes stakeholder engagement and capacity building. |
| **Challenges**              | - Complex data collection and analysis.<br>- Requires ongoing updates as climate conditions and site conditions change.<br>- Ensuring broad stakeholder participation for comprehensive assessments. |

| **Year** | **CVI Application** | **OUV Reassessment** | **Notes** |
|----------|----------------------|----------------------|-----------|
| **2019** | - Applied to Heart of Neolithic Orkney (Scotland)<br>- Application for Shark Bay (Australia) | None | - CVI began to be notably used, with these being among the first sites assessed. |
| **2020** | - Wadden Sea (Germany, Netherlands, Denmark)<br>- Orkney follow-up assessments | None | - Continued application, focusing on marine and cultural sites. |
| **2021** | - Sukur Cultural Landscape (Nigeria)<br>- Wadden Sea community vulnerability | None | - More assessments, including in Africa and follow-ups on previous sites. |
| **2022** | - Old and New Towns of Edinburgh (Scotland)<br>- Further marine site assessments | None | - CVI used in urban settings and for broader marine conservation planning. |
| **2023** | - Various online workshops and assessments<br>- Continued focus on marine resilience | None | - Increased use of virtual platforms for CVI assessments due to global circumstances. |
| **2024** | - Hypothetical ongoing assessments (data not publicly detailed) | Potential reassessment for select sites | - Continued application without specific public records of each site. |
| **2025** | - Hypothetical ongoing assessments (data not publicly detailed) | Potential reassessment for select sites | - Same as 2024, with ongoing application but no specific yearly data. |

**Notes:**
- **CVI Application**: Refers to known or documented uses of the CVI for specific sites. This list is not exhaustive as not all applications are widely publicized or documented in real-time.
- **OUV Reassessment**: While OUV is assessed at the time of inscription, there can be periodic reviews if significant changes occur, but these are not annual events.
- **Hypothetical entries for 2024 and 2025** reflect that CVI might be in use but specific data might not be systematically recorded or made public on an annual basis for all sites.
