Summary
Sustainable urban ocean management is crucial. Emerging approaches and economic tools can reduce urban pressures, restore ecosystems, and support vital services, benefiting both people and nature.
Area of Science:
- Marine biology
- Urban ecology
- Environmental science
Background:
- Urban and periurban ocean developments impact 1.5% of global exclusive economic zones.
- Increasing demand for ocean space and resources necessitates sustainable management.
Purpose of the Study:
- Identify key objectives for sustainable urban oceans: reducing urban pressures, protecting/restoring ecosystems, and supporting ecosystem services.
- Describe evidence-based approaches and economic instruments for sustainable urban ocean management.
Main Methods:
- Review of emerging evidence-based approaches (e.g., greening infrastructure, habitat restoration, biotechnologies).
- Exploration and evaluation of new economic instruments and incentives.
Main Results:
- Several tools can reintegrate nature into urban oceans.
- Approaches offer potential for climate adaptation, seafood production, clean water, and recreation.
Conclusions:
- Sustainable urban ocean management requires a multi-faceted approach combining ecological restoration with economic incentives.
- These strategies can yield significant human and environmental benefits in highly impacted marine areas.

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

01:06Primary Production
24.8K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
