We show that time allocation could be used as an indicator of the effects of oil palm expansion and adoption on well-being and that potential effects of time scarcity should be considered by policy makers when making land use decisions.

Mobile phone diffusion has a positive association with rural healthcare access. However, the potential behavioural consequences of ‘‘informal mHealth” reinforce the notion that mobile phones are a non-neutral platform for mHealth and development interventions.

Improved crop diversity over the year is positively associated with dietary diversity in the regular season, but not in the lean season. Livestock species diversity remains important for dietary diversity throughout the year, but particularly so in the lean season when the influence of cropping diversity is low.
