Adding more ingredients to the cooking energy sector Image Cooking is a vital daily activity for families around the world, yet 2.8 million people lack access to clean cooking fuels and technologies (SDG7 Tracking Report, 2020). While we have known the scale of the problem over the last decade, the sector has lacked deeper insights to guide policy makers and practitioners. Cooking behavior is complex and highly contextual: it is a development issue affecting health, environment, climate change, and gender equality. Only when we understand the obstacles, gaps, and needs in this sector can we work towards developing appropriate and sustainable solutions.
