Figure 3. Relationship between milk yield per head (x-axis) and emission intensity of milk production for livestock-keeping smallholder households in Kenya, expressed as a population-level scatter plot (A) and an interpolated probability density surface (B). The vertical lines in (B) highlight slices through the density surface at productivity levels of 2000 (red) and 3000 (blue) kg milk head-1 year-1 (shown in Figure 4B).
