Abstract Background Removals caused by both natural and anthropogenic drivers such as logging and fire causes substantial carbon emissions. Better insights into drivers and their variations of aboveground carbon removals is therefore needed. We assessed the drivers of aboveground carbon (AGC) removals and quantified the dynamics of removals-induced carbon emissions due to drivers using the National Forest Resources Assessment and Monitoring (NAFORMA) data sets in R software. Miombo woodlands which is the largest forest formations covering about 93% of forest land in mainland Tanzania was the case study. Results Drivers of AGC removals in miombo woodlands of mainland Tanzania in order of importance were; timber, fire, shifting cultivation, charcoal, natural death, firewood collection, poles, grazing by wildlife animals, carvings, grazing by domestic animals, and mining. The average AGC removals by drivers range from 0.0–1.273tCha− 1year− 1. Conclusions Increased mitigation efforts in addressing removals by timber, fires, shifting cultivation, charcoal and natural death would be effective in addressing forest degradation in the REDD + process in Tanzania. Since NAFORMA provides national picture on drivers and their variation on AGC removals, site-specific studies need to be conducted to bring information that would be used for local forest management. This kind of study need to be conducted in other vegetation types like Montane and Mangrove forest in Tanzania.

Shifting cultivation is a type of farming without fixed boundaries. It obeys an ecological logic but requires constant improvisation and adaptation to fluid circumstances. The character of improvisation in shifting cultivation is explored with reference to an African case study (rice farming by the Mende people of Sierra Leone). Two elements are emphasized in particular—the management of fire (by men) and rice seeds (by women). A contrast, applicable not only to farming, but also to other activities such as military conflict and musical performance, is drawn between strategic planning and tactical improvisation. The relevance of Mary Douglas’s grid-group theory to the framing of the social skill sets required for improvisation is discussed.
