The role of coastal blue carbon ecosystems in climate mitigation and adaptation efforts has been recognized. Blue carbon ecosystem functionality is one component of coastal naturebased or green-gray infrastructure multifunctionality, which includes contributions by nature to disaster risk reduction, infrastructure resilience, erosion control, land formation, and other ecosystem services. Here we review how green infrastructure and nature-based solutions in coastal and shallow nearshore areas can contribute to blue climate change mitigation and adaptation. We then summarize available coastal infrastructure types (green, gray, and greengray hybrid) in terms of their inherent functions and potential co-benefits. We discuss technologies for integrating gray and green infrastructure and producing hybrid infrastructure to promote implementation of measures for both climate change and infrastructure development, although the best infrastructure type is dependent on the risks of a given time and locality. Collaboration among engineers, scientists, and economists who are interested in climate change or infrastructure and in emerging fields such as blue carbon and green infrastructure are needed to further enhance the implementation of multifunctional infrastructure, but the multifunctionality benefits should be quantified and monetized.

The catch of Manila clams in Japan has drastically decreased recently. It is necessary to promote the growth of benthic microalgae, which is their main feed, for the reproduction of tidal flats where clams grow. In this study, we applied dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorus (DIP), and Fe-eluting fertilizer to tidal flats surrounded by a sealing plate to prevent fertilizer outflow. We found that DIN and DIP in pore waters and chlorophyll a in the surface sediments almost increased in concentration at fertilizing sites. However, periods of nutrient elution from the fertilizer were considered to be less than half a year In addition, the weight of clams collected from the 1600g fertilizing site was significantly greater (t-test, p<0.05) than that from the control area. Consequently, the total weights of clams collected from the control site and fertilizing sites increased to approximately 7.2 and 10.4-12.6 times greater than the initial weights, respectively, four months after the experiment started. In conclusion, using a combination of fertilizers and sealing plates is effective for increasing the weight of clams inhabiting the tidal flats.
