Nature-based assets refer to natural resources and ecosystems, such as forests, wetlands, and coral reefs, that provide valuable goods and services to human society, such as water filtration, flood control, carbon sequestration, and habitat for wildlife.
These assets can also have economic value and can be managed for sustainable use. They are increasingly recognized as important for addressing global challenges such as climate change, biodiversity loss, and human well-being.
Blue Carbon refers to the carbon captured and stored by coastal and marine ecosystems, such as mangroves, seagrasses, and tidal marshes. These ecosystems are highly efficient at capturing and storing carbon and play a critical role in mitigating the impacts of climate change.
Blue carbon provides a range of other ecosystem services, including shoreline protection, wildlife habitat, and support for fisheries, making it a valuable and important component of the world's coastal and marine ecosystems.
Mangroves are salt-tolerant trees and shrubs that grow in the intertidal zones of tropical and subtropical coastal areas. They play an important role in coastal ecosystems, providing habitat for a diverse array of wildlife, protecting shorelines from erosion, and serving as important nursery grounds for many commercially important fish species.
Mangroves also store large amounts of carbon in their soils and vegetation, making them an important component of the global carbon cycle and a significant contributor to the "blue carbon" sink.
However, mangroves are under threat from human activities such as deforestation, coastal development, and aquaculture, and the loss of mangrove ecosystems can have negative impacts on both the environment and local communities.
Seagrasses are a group of flowering plants that grow in coastal waters, typically in shallow bays and estuaries. They provide important habitats for many marine species, help reduce erosion, and play a role in carbon sequestration.
Some common species of seagrasses include eelgrass, turtle grass, and manatee grass. However, seagrass populations are declining worldwide due to human activities such as coastal development and pollution.
Tidal marshes are coastal wetlands that are influenced by the rise and fall of tides. They are located between land and open water and are found along sheltered coasts, such as bays and estuaries. Tidal marshes are rich in biodiversity and provide important habitats for many species of plants and animals, including migratory birds and fish.
They also play a role in mitigating the impacts of storms and sea level rise by absorbing and reducing wave energy. However, tidal marshes are under threat from human activities such as coastal development and sea level rise.
