Approaches to restoration per ecosystem type

As mentioned previously, there are different types of ecosystems, each with their main components and interactions, providing a number of services crucial for sustaining livelihoods. Throughout the different types of ecosystems the level of degradation and major threats vary, which means the approach to restoring these ecosystems also differ.

Linking indigenous species with urban ecosystem services in restoration efforts

Cities need to know where to prioritize investment for their restoration efforts, and this requires an understanding of the biodiversity and landscapes within the area. Successful ecosystem restoration efforts depend on the availability of data and information on the relevant ecosystems, including the changes in land use and ecological integrity. Accordingly, Dar es Salaam has developed a native biodiversity catalogue as part of the Integrated Action on Biodiversity (INTERACT-Bio) project. This project is funded by the International Climate Initiative (IKI) supported by the Federal Ministry for Economic Affairs and Climate Action (BMWK) in close cooperation with the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV). The aim of the catalogue is to inspire awareness of the uniqueness of the city’s natural heritage (being located in a biodiversity hotspot), the role and importance of native fauna and flora for local conservation efforts, local economies and for mitigating risks associated with climate change, food security and public health. Its development utilized assessments of the city’s biodiversity and ecosystems based on the selection of a subset of fauna and flora species in the city, making it a useful resource for understanding opportunities to purposefully incorporate local biodiversity and ecosystem services into greening plans as well as grey infrastructure developments.
