Figure 6. Timeline of the major events that contributed to the development and diffusion of the crested ibis rice certification scheme.

Events were clustered under exogenous factors, three levers and seven leverage points referring to (Chan et al., Citation2020). Lower-case letters in parentheses after event names refer the leverage point (LP) categories shown in . The black four-pointed star (✦) indicates the year of a one-off event, while the grey band shows the period of a consecutive event.
