  • Incorporating ecosystem services into the implementation of existing U.S. natural resource management regulations: Operationalizing carbon sequestration and storageFrom Abstract: Many agencies and organizations, including the U.S. federal government, are expressing interest in the measurement and valuation of ecosystem services.

  • Paleoreconstruction of estuarine sediments reveal human-induced weakening of coastal carbon sinksFrom Abstract: “We reconstructed the sedimentary records of cores taken from two sites within Botany Bay, Sydney – the site of European settlement of Australia – to look for human-induced changes in dominant sources of detritus in this estuary. Given the lower carbon burial efficiencies of microalgae (~0.1%) relative to seagrasses and C3 terres- trial plants (up to 10%), such changes represent a substantial weakening of the carbon sink potential of Botany Bay – this occurrence is likely to be common to human-impacted estuaries, and has consequences for the role these systems play in helping to mitigate climate change.”Macreadie, P.I., Allen, K., Kelaher, B.P., Ralph, P.J., Skilbeck, C.G.

  • State of the science on coastal blue carbon: A summary for policy makersFrom Summary: “This report examines the current science as it relates to [how coastal habitats sequester and store carbon, where on the planet carbon is stored in these habitats, how rapidly the habitat is being modified with a risk of carbon release, and the mechanisms and rate of carbon emissions that follow conversion]. In doing so, it aims to give policy makers a feel for what is known and unknown about coastal blue carbon.”Sifleet, S., Pendelton, L., & Murray, B.

  • Green Payments for Blue Carbon Economic Incentives for Protecting Threatened Coastal HabitatsFrom Abstract: This report examines the critical question of whether monetary payments for blue carbon can alter economic incentives to favor protection of coastal habitats. Like payments for REDD+, incentives to retain rather than emit blue carbon would preserve biodiversity as well as a variety of other ecosystem services at local and regional scales.Murray, B.C., Linwood, P., Jenkins, W.A., & Sifleet, S Nicholas Institute for Environmental Policy Solutions Report.

  • Addressing climate change adaptation and mitigation in tropical wetland ecosystems of IndonesiaFrom Abstract: “Tropical wetlands, especially peatlands and mangroves, are important in global carbon cycling… Standardized methods and protocols are needed for conservation and reduction of degradation to tropical wetlands. This is not only a sound mitigation approach, but is also an important adaptation strategy to climate change effects. Ecosystem-based or whole watershed approaches could provide the best options for communities to cope with changing climate conditions.”Murdiyarso, D., & Kauffman, J.B. CIFOR. Infobrief 41 (2011)
  • Carbon storage in mangrove and peatland ecosystems: A preliminary account from plots in IndonesiaFrom Abstract: The paper reviews total ecosystem carbon storage in mangrove ecosystems in North Sulawesi, Central Kalimantan and Central Java, Indonesia. Scientists assessed variations in mangrove carbon pools as well as their vulnerability to sea-level rise and land use.Murdiyarso, D., Donato, D., Kauffman, J.B., Kurnianto, S., Stidham, M., & Kanninen, M. Working Paper 48 (2009)
  • Blue carbon: The role of healthy oceans in binding carbonFrom Abstract: This report reviews the current rate of loss of coastal wetlands and argues that, “if we are going to tackle climate change, we need to recognize the role and the contribution of all the colours of carbon.”Nellemann, C., Corcoran, E., Duarte, C.M., Valdes, L., De Young, C., Fonseca, L., & Grimsditch, G.
