Enhancing Climate Adaptation with Earth Observations: A Global Perspective

As Global Climate Shifts Intensify, Adaptation Takes Center Stage

With climate change impacts accelerating, adaptation strategies are becoming increasingly critical for safeguarding ecosystems and improving quality of life. The 28th Conference of the Parties (COP28) of the UN Framework Convention on Climate Change (UNFCCC) in the UAE emphasized this urgency by establishing the UAE Framework for Global Climate Resilience. The mandate to develop adaptation indicators aims to track progress effectively. However, questions remain about the data sources for these indicators and how they can best serve the needs of Parties to the Paris Agreement.

A forum titled ‘Using Earth Observations Systems to Improve Climate Adaptation Policy and Action’ convened in Bern, Switzerland, discussed the potential of space-based Earth Observations (EO) data in supporting adaptation efforts. Hosted by the International Space Science Institute in collaboration with several space and policy agencies, the forum explored EO data’s role in addressing the UAE-Belem work program’s needs. This initiative seeks to integrate EO data into adaptation indicators under the UAE Framework for Global Climate Resilience.

Adaptation: A Global Imperative

Adaptation involves adjusting to climate impacts to minimize harm and exploit opportunities¹. Historically viewed as a local issue², the transboundary nature of climate risks now demands a global approach³. International efforts are focusing on enhancing adaptation actions, necessitated by experienced and projected climatic changes^5,6.

Adaptation requires understanding the risk of climate hazards, reducing exposure, and managing vulnerabilities. Risk is defined as “potential for adverse consequences for human or ecological systems,” arising from climate change impacts and human responses⁷. Despite efforts, current global climate targets remain unmet⁸, underscoring the urgency for intensified action⁹.

Global Adaptation Efforts and the Framework on Adaptation

Significant progress under the UNFCCC and the Paris Agreement has highlighted adaptation’s importance¹⁰. The Paris Agreement’s Article 7 outlines the Global Goal on Adaptation (GGA) to “enhance adaptive capacity, strengthen resilience, and reduce vulnerability to climate change”¹¹. It encourages countries to develop National Adaptation Plans and report on adaptation efforts through various communications.

The GGA framework now includes 11 global targets, covering themes such as water, agriculture, health, ecosystems, infrastructure, poverty, and cultural heritage. Four targets relate to the policy cycle: Impact Assessment, Planning, Implementation, and Monitoring. These targets aim for a comprehensive adaptation response by 2030 and beyond, with adaptation indicators expected to be finalized by COP30 in 2025.

Earth Observation-Based Adaptation Indicators

EO data offers unique capabilities for creating adaptation indicators, despite the complexities of adaptation¹⁸. EO data, particularly satellite-based, provides objectivity, repeatability, broad coverage, and long-term data continuity. These strengths make EO valuable for tracking adaptation progress and assessing impacts on agriculture, biodiversity, extreme events, and health.

EO data is instrumental in risk assessment, identifying areas needing adaptation, and monitoring intervention implementation. It supports modeling causal effects of climate hazards and evaluating adaptation measures. EO’s role in measuring adaptation outcomes is crucial, although it must be used alongside socio-economic data for a complete picture²³.

Challenges in Using EO for Adaptation

Several challenges must be addressed for EO to effectively support adaptation. Key issues include establishing accurate baselines, maximizing data utility, disaggregating data to understand vulnerability, and integrating past data with future projections. Overcoming these challenges will enhance EO’s contribution to the adaptation process.

Learning from Sustainable Development Goals Indicators

The Sustainable Development Goals (SDGs) offer insights for developing global adaptation indicators. A study by the European Space Agency highlighted EO’s potential for SDG indicators, identifying areas where EO can contribute significantly. These insights can guide the development of adaptation indicators under the GGA framework, leveraging EO’s strengths in monitoring environmental changes.

Recommendations for Leveraging EO in Adaptation

To enhance EO’s role in climate adaptation, recommendations include integrating EO data into adaptation indicators, fostering collaboration between EO agencies and adaptation experts, and investing in research to address knowledge gaps. These actions can drive effective adaptation strategies, leveraging EO’s capabilities to address global climate challenges.
