Carbon-optimised land management strategies for southern Amazonia

Contrasting methane emissions from upstream and downstream rivers and their associated subtropical reservoir in eastern China

“…2) are driven by bubbles (see Supplementary Table S4). In contrast to other studies 21,24 , we found that bubbles occurred in the deep-water zone (>10 m) rather than in the shallow zone (<5 m), and we suggest that the high ebullitive CH 4 emissions from deep water zones are related to heterogeneous sediment accumulation 12,13 because little or no sediment accumulates along reservoir margins 39 .…”

“…Similarly, CH 4 emission levels from outlets downstream and inflow rivers upstream of reservoirs were distinct from those of the reservoir water 7,17,18 , due to variability in hydrological variables, such as water velocity and depth 2 , and dam operation strategy 19 . Temporal variability in CH 4 emissions has been attributed to changes in temperature, water column mixing, dissolved oxygen (DO) concentration, and other environmental variables, including retention time and benthic metabolism 2,20,21 . For example, CH 4 emissions were greater in summer than in other seasons at the Three Gorges Reservoir and were regulated by temperature, DO, and water velocity 2 , whereas they were only regulated by temperature at three lakes (Följesjön, Erssjön, and Skottenesjön) in southwest Sweden 20 .…”

Communications on Climate Change and Biodiversity Loss with Local Populations: Exploring Best-practices and Postcolonial Moments in Eight Case Studies from across the Globe

“…Jointly, the two sub-projects entered in collaboration with the local indigenous organisation at one of the research hotspots in the Northern part of the highway. The collaboration aimed at researching soil carbon stocks in the indigenous territories, the last pristine forest areas in a region with fast-changing land-use patterns and growing cattle and soybean cultivation (Gerold et al, 2018). The research team consisted of several soil science researchers (PhDs, master students, and PostDocs), two social scientists, a local well builder, and several indigenous representatives.…”
