Bottom Line: Published research on these technologies focuses on their potential to reduce indoor air pollution and improve respiratory health.We compare treatment households who are supplied with a biogas cook stove with comparison households who do not have access to these stoves, while controlling for several socio-economic factors.To inform development investments and ensure these co-benefits, we argue that multiple dimensions of sustainability should be considered in evaluating the impact of alternative cook stoves.

ABSTRACT
Alternative cook stoves that replace solid fuels with cleaner energy sources, such as biogas, are gaining popularity in low-income settings across Asia, Africa, and South America. Published research on these technologies focuses on their potential to reduce indoor air pollution and improve respiratory health. Effects on other cooking-related aspects, such as diets and women's time management, are less understood. In this study, in southern India, we investigate if using biogas cook stoves alters household diets and women's time management. We compare treatment households who are supplied with a biogas cook stove with comparison households who do not have access to these stoves, while controlling for several socio-economic factors. We find that diets of treatment households are more diverse than diets of comparison households. In addition, women from treatment households spend on average 40 min less cooking and 70 min less collecting firewood per day than women in comparison households. This study illustrates that alongside known benefits for respiratory health, using alternative cook stoves may benefit household diets and free up women's time. To inform development investments and ensure these co-benefits, we argue that multiple dimensions of sustainability should be considered in evaluating the impact of alternative cook stoves.

Mentions: We surveyed 199 households in 15 ADATS member villages (Figure 2; Table S1 in Supplementary Material) from the Bagepalli panchayat in the Kolar district of Karnataka (Figure 1) (51–53). The Bagepalli panchayat skirts the southern border of the Rayalaseema desert. The terrain is semi-arid and drought prone, with rainfall averaging 560 mm/year (54). The majority of families in the region are labor workers, while a few tend their own agricultural plots.
