Implementation and availability of management practices for SPW control in different regions. a Pictorial comparison of SPW control measures in the USA and SSA. The size of the circle around each respective control measure approximates its perceived level of current implementation. In addition, the gray shading for certain foundational practices indicates it is in need of strengthening or increased implementation. b Detailed assessment of SPW control measures in the USA versus SSA. The assessment of implementation is approximated with a High, Medium, or Low ranking (e.g. high = routinely implemented or in place as well-established in the region, low = not widely implemented or poorly established), with comments on perceived availability of the respective practice
