Study Notes

Nature-based Solutions: An Overview

Nature-based solutions (NbS) are actions that address societal challenges through the protection, sustainable management, and restoration of natural or modified ecosystems.
NbS offer a range of benefits, including mitigating climate change, adapting to its impacts, and preserving biodiversity.

Examples of Nature-based Solutions

Protecting and restoring coral reefs: This helps safeguard coastal communities from erosion and storm surges.
Keeping forests standing: Forests play a crucial role in carbon sequestration and regulating water cycles.
Building greener cities: Incorporating green spaces and urban forests helps reduce heat islands and improves air quality.

NbS and Ecosystem Services

NbS focus on practical solutions to address specific problems.
Ecosystem services involve understanding and valuing the benefits ecosystems provide.
NbS implement practices and strategies, while ecosystem services offer a framework for evaluating and quantifying ecosystem benefits.

Nature-based Solutions in EU-Funded Projects

Sentinel projects showcase successful examples of NbS implementation.
Mapping evidences demonstrate the effectiveness of NbS in reducing greenhouse gas emissions and mitigating climate change.

Nexus and Scale of NbS Application

The scale of application influences the effectiveness of NbS.
Challenges in implementing NbS include limited understanding, lack of funding, and potential conflicts with existing infrastructure.

Selection of NbS: Cost-effectiveness and Variability

Cost-effective solutions are essential for widespread implementation.
NbS variability spans from ocean-based solutions to inland interventions, reflecting the diverse nature of coastal ecosystems.

Resilience and Coastal Systems

Resilience refers to a system's ability to withstand and adapt to external pressures.
NbS enhance resilience by replicating natural processes and integrating with existing infrastructure.
The resilience of coastal systems is crucial for mitigating climate change impacts.

Climate Resilience and Risk Reduction

NbS play a crucial role in climate resilience by reducing disaster risk.
Transforming disaster risk reduction involves promoting integrated approaches that integrate NbS with traditional engineering solutions.

Social acceptance is vital for the successful implementation of NbS.
Engaging stakeholders in developing frameworks for assessing NbS effectiveness is crucial for fostering collaboration and ensuring project success.

Replicability of NbS

Replicability is crucial for scaling up NbS and achieving widespread impact.
Barriers to replicating and up-scaling include policy limitations, inadequate funding, and limited awareness.

Blue NbS: Coastal and Oceanic Climate Action

Blue NbS focus on harnessing the potential of oceans and coastal ecosystems to mitigate climate change.
Blue carbon refers to carbon stored in coastal and marine ecosystems.

The Future of Nature-based Solutions

Cost-effective solutions are paramount for widespread implementation.
NbS offer a promising avenue for addressing societal challenges, but ongoing research, collaboration, and policy changes are needed to unlock their full potential.
