Topic C1. Reducing emissions and enhancing removals (land-use change, fire, drainage) J Boone Kauffman and Daniel Murdiyarso

Topic C1. Slide 2 of 21 Implementing mitigation (emissions reduction) strategies in forests Why it is important to act now? Intact/Restored ecosystems:  are more buffered (resistant) to collapse or decline with a changing climate or other stresses;  have a higher degree of resilience – the capacity to recover following stress or disturbance;  will provide more ecosystem services – e.g. biodiversity, water quality, aesthetics and carbon storage;  may be of value and interest for carbon financing for climate change mitigation

Topic C1. Slide 3 of 21 Carbon sequestration is an ecosystem service that has not received value until recently Net primary productivity (NPP) - The net amount of fixed C in organic matter by photosynthesis after the needs of the plant have been met. GPP- Respiration = NPP About 95% of CO 2 emissions would occur if humans did not exist on Earth - natural decay of plant materials is about 220 billion tonnes of CO 2 each year.

Topic C1. Slide 4 of 21 Tropical forested wetlands are ecosystems that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support a prevalence of forest vegetation typically adapted for life in saturated soil conditions (e.g. mangroves, freshwater swamps, floodplain forests).

Topic C1. Slide 5 of 21 How much carbon can be found in forests? Donato et al. 2011, Kauffman et al. In press, Kauffman et al 2003.

Topic C1. Slide 8 of 21 We need to determine the pathways and processes of emissions

Topic C1. Slide 9 of 21 Currently, on average, between 1-7% of blue carbon sinks are being lost annually Upstream disruptionsAquaculture Rice/Agriculture Road development/ hydrological disruptions Coastal development

Topic C1. Slide 10 of 21 Currently, the impacts of land use/land cover change are impacting biodiversity to a much greater extent than global climate change

Topic C1. Slide 12 of 21 How to determine emissions from land-use/land-cover change Gain-loss method Stock difference method

Topic C1. Slide 13 of 21 Stock difference method (C t2 – C t1 ) (t 2 – t 1 ) ΔC = annual carbon stock change in the pool C t1 = carbon stock in the pool at time t 1 C t2 = carbon stock in the pool at time t 2 C stock at time 1 C stock at time 2 ΔC =
