The low estimate, 300 cm, is the upper end of depth reported by the MoA maps; the high estimate is the midpoint of the 800 1200 cm deepest depth class used in the WI maps (Kalimantan) and the medium estimate is the midpoint of the 300 cm minimum and 1200 cm maximum reported for the deepest depth class in the MoA and WI (Kalimantan) maps respectively.
As a medium estimate, we took an approximate average of these percentages, assuming that large whales constitute 25% of historical numbers and small cetaceans 50%.
NA: not available Future projection of Japanese population (medium estimate) by National Institute of Population and Social Security Research predicted a gradual decrease (127.6 million in 2008, 125.9 million in 2014 and 122.7 million in 2020), and a proportion of 65 years old or older was predicted to gradually increase (22.1%, 26.2% and 29.2%, respectively) [ 12](Table 3).
Similarly, 14.77 GtC are estimated in depth classes >400 cm on the WI maps; about 48% of the 30.79 GtC medium estimate.
We selected a medium density estimate of 50,000 km -2 (Medium), roughly midway between high and low estimates.
Calculation of effects for 100% equipment rate The effect estimates for safety, mobility and comfort were used to calculate the overall low, medium and high estimates of the effect of the system.
Low, medium and high estimates of total peat volume for the WI maps are: 298, 476, and 643 km3, respectively, whereas for MoA maps they are 210, 391, and 519 km3, respectively (Additional file 1: Tables 6 10).
Low, medium and high estimates of peat carbon storage for the WI maps are 19.23, 30.79 and 40.49 GtC, respectively (Table 6); and are 13.56, 25.33, and 33.77 GtC, for the MoA map, respectively (Table 7).
Raw population projection data from the most recent population report in Rwanda (National Institute of Statistics of Rwanda 2009) were used to create best-fit curves for high, medium and low estimates of various male population age cohorts.
