Fig. A1. (A) Location of our study region (Kilwa District) in Tanzania and (B–D) the distribution of plots within each of the village areas where sampling was undertaken. Dark patches show areas of high eleveation. Plot co-ordinates are provided in Table A1.

Fig. A2. The soil textures of the 67 sites. The graph highlights the considerable variation in texture across our sample plots, ranging from 91% sand and 8% clay on our most coarse textured sites, to 63% sand and 31% clay. Plots were separated 18% clay content threshold (FAO, 2006). The mean (±SD) clay content in plots classified as sandy was 11.5 (2.7) %, and 24.0 (3.5) % on the sandy clay (loam) soils. Clay contents were non-normally distributed within both groups, with plots clustering at around 8 – 10% for sandy soils and 20 – 22% sandy clay loams, but with a tail of increasingly fine textured soils in both groups. On one plot classified as being on a clay soil, texture was estimated by hand instead. On the sandy soils, some plots had similar soil textures meaning there is some overlap in the points.
