In this podcast by social impact careers organisation 80,000 Hours, engineer David Denkenberger argues that it would be possible to feed everyone even in the event of a disaster that disrupts agriculture, such as a nuclear winter or asteroid strike.

This book, by Jeremy Allouche, Carl Middleton and Dipak Gyawali, describes and critiques different understandings of the concept of the “nexus” between water, food and energy.

This book explores 18 case studies of family farming across several continents through a ‘sustainable rural livelihood’ framework. The authors are from both academia and development bodies.

The UK’s Global Food Security programme has published a report on innovation within the UK food systems, focusing particularly on the contribution of data technologies and artificial intelligence to food security.

This report from the Ellen MacArthur Foundation outlines three ways in which cities can promote a circular food economy: source food grown regeneratively and (when appropriate) locally; reduce waste and use by-products; and design and market healthier food.

Canada’s new dietary guidelines include environmental considerations as well as health, suggesting that diets higher in plant-based foods generally help to conserve “soil, water and air”.

This paper models the system-wide changes and consequent shifts in pre-retail greenhouse gas emissions that might result from introducing a Europe- or North American-style refrigerated food chain to sub-Saharan Africa. Total emissions might increase or decrease, depending on the scenario.

This paper presents a ‘carbon benefits index’ to measure how land use change contributes to global carbon storage and reduction in greenhouse gas emissions. The index accounts for both the carbon that could be stored if the land were reforested, and the carbon emissions of producing the same food elsewhere.

This paper presents the Open Source Seed (OSS) Licence, a new legal instrument (inspired by open source software) designed to protect access to plant germplasm as a commons accessible to everyone. The legally enforceable licence is being trialled with varieties of tomato, wheat and maize.
