This case demonstrates the utility of the 3Es (effectiveness, efficiency, and equity) in examining Reducing Emissions from Deforestation and Forest Degradation (REDD+) project in Nepal. REDD+ offers results-based payments for conserving and managing forests sustainably and enhancing forest carbon stocks. This will benefit communities’ efforts to conserve forest resources and prevent deforestation; conserving integrity of forests in turn benefits the global carbon budget. This case uses the 3Es to examine one case in Nepal of distributing the REDD+ funds among local participants. Of the 3Es, equity is getting attention worldwide but there is still debate on which principle of 3Es should be given priority to achieve overall effectiveness of REDD+. This case finds that equity is a fundamental requirement to achieve the other Es (efficiency and effectiveness) in REDD+ implementation. Further, I find that distributive equity is the most important and understood in three different ways in Nepal: rights, needs, and performance. There is an argument between communities and experts on which equity should be given priority. I recommend that the issue of needs based equity vs. performance-based equity should be solved by formation of guidelines of sharing benefits at two levels. First, the benefit distribution from international sources/markets to community forest user groups should be based on the ownership of carbon and performance of communities participating in REDD+. Second, at community level, communities should decide on the form of benefit distribution according to their needs. The primacy of equity in this case will likely find international echoes in other environmental policies and in other countries.

Wildfires in the Arctic tundra have become increasingly frequent in recent years and have important implications for tundra ecosystems and for the global carbon cycle. Lake sediment–based records are the primary means of understanding the climatic influences on tundra fires. Sedimentary charcoal has been used to infer climate-driven changes in tundra fire frequency but thus far cannot differentiate characteristics of the vegetation burnt during fire events. In forested ecosystems, charcoal morphologies have been used to distinguish changes in fuel type consumed by wildfires of the past; however, no such approach has been developed for tundra ecosystems. We show experimentally that charcoal morphologies can be used to differentiate graminoid (mean = 6.77; standard deviation (SD) = 0.23) and shrub (mean = 2.42; SD = 1.86) biomass burnt in tundra fire records. This study is a first step needed to construct more nuanced tundra wildfire histories and to understand how wildfire will impact the region as vegetation and fire change in the future.

Seasonal variations of atmospheric carbon dioxide (CO2) in the Northern Hemisphere have increased since the 1950s, but sparse observations have prevented a clear assessment of the patterns of long-term change and the underlying mechanisms. We compare recent aircraft-based observations of CO2 above the North Pacific and Arctic Oceans to earlier data from 1958 to 1961 and find that the seasonal amplitude at altitudes of 3 to 6 km increased by 50% for 45° to 90°N but by less than 25% for 10° to 45°N. An increase of 30 to 60% in the seasonal exchange of CO2 by northern extratropical land ecosystems, focused on boreal forests, is implicated, substantially more than simulated by current land ecosystem models. The observations appear to signal large ecological changes in northern forests and a major shift in the global carbon cycle.
