  abstract = {{W}etland soils are an important component of the {G}lobal {C}arbon {C}ycle because they store about 20-25% of the terrestrial soil organic carbon ({SOC}). {W}etlands occupy about 6% of the global land surface and any change in their use or management has potentially dramatic consequences on greenhouse gases emissions. {H}owever, the capacity of wetland soils to store carbon ({C}) differs from place to place due to reasons still not well understood. {T}he objective of this review was to evaluate the global variations in wetlands {SOC} content ({SOC}c) and to relate it to key soil and environmental factors such as soil texture, intensity of soil hydromorphy, metallic element content and climate. {A} comprehensive data analysis was performed using 122 soil profiles from 29 studies performed under temperate, humid, sub-humid, tropical and sub-arctic conditions. {T}he results point to average {SOC}c of 53.5 +/- 15.8 g {C} kg(-1) with a maximum of 540 g {C} kg(-1). {SOC}c increased with increase in intensity of soil hydromorphy (r = - 0.52), {A}l (r = 0.19) and {F}e content (r = 0.21), and decreased with soil p{H} (r = - 0.24). {T}here was also a surprising tendency for intensity of soil hydromorphy, and thus {SOC}c, to decrease with increasing mean annual precipitation and soil clay content. {T}hese results contribute to a better understanding of the impact of soil hydromorphy in wetlands on organic {C} stabilization in the soils. {H}owever, further studies with additional information on soil bulk density to assess carbon {C} stocks, still need to be performed.},
