Fig. 6: Global drivers of mangrove gross gain.
From: Drivers of global mangrove loss and gain in social-ecological systems
Fixed effects of socioeconomic and biophysical variables on percent gross gain of mangrove cover in 1996–2007 (a; n = 2341 mangrove geomorphic units across 55 countries) and 2007–2016 (b; n = 2554 mangrove geomorphic units across 59 countries) showing the estimate and 95% confidence intervals from the mixed-effects models. Positive values (in blue) indicate mangrove gain increased with an increase in the variable, while negative values (in red) indicate mangrove gain decreased with an increase in the variable. NDC Nationally Determined Contribution. SLR sea-level rise. Relationship between percent gross gain 2007–2016 and travel time to nearest city (c), night-time lights growth (d), and community forestry effort (e) from the mixed-effects model (n = 2554), showing the fitted regression line and 95% confidence intervals. N.S. not significant. f Percent gross gain across mangrove geomorphic types in 1996–2007 (n = 2341) and 2007–2016 (n = 2554) showing the median, 25th and 75th percentiles at the lower and upper hinges, and whiskers extending to the smallest and largest values at most 1.5 × inter-quartile range. P-values derived from two sample t-tests. Asterisks indicate significant effects at p < 0.05*, p < 0.01**, and p < 0.001***. Corresponding t-values and p-values for each variable are provided in Supplementary Table 10.
