Systematic review study on carbon stocks and fluxes associated with LULCC in mangroves

1 21 4

Goal and Objectives

2

• Primary review question:• How does land-use and land-cover changes

(LULCC) affect carbon stocks and fluxes of mangrove ecosystems?

• Secondary review questions:• What is the magnitude of mangrove carbon

stocks and flux changes in relation to types of LULCC identified?

• How do different LULCC impact mangrove carbon stocks and fluxes?

• What are the implications of LULCC, disturbance and restoration activities to global mangrove ecosystems carbon loss and gain respectively?

Summary

13

• The impacts of mangrove C storage and fluxes to LULCC and disturbance

• Mangrove carbon topic is well-recognized (5 key papers)

• Systematic review requires transparent and consistent steps

• Mangrove conversion to other LULC may leads C emissions, while conservation-based activities have C gain impacts

• More field data are required
