This paper describes a method for irrigating agricultural soils in areas that are prone to drought or do not have access to water supplies. The system is based on a “super moisture absorbent gel” (SMAG), which absorbs moisture from the atmosphere and then releases it to the crops when heated by the sun. 

This report from UK think tank Chatham House uses a literature review to identify three key levers that, it argues, are all essential for transforming food systems: encouraging plant-based diets, setting aside land for nature, and shifting to more sustainable farming.

UK NGO Eating Better has launched a new framework to guide retailers and restaurants towards sourcing “better” meat, in line with its aim of halving UK meat and dairy consumption by 2050 and transitioning to “better” meat and dairy as standard.

This report from WorldFish (an international organisation that researches aquatic systems, with a focus on sustainable development in low- and middle-income countries) sets out a research strategy for sustainable and equitable global aquatic food systems for the next decade. Aquatic foods include finfish, shellfish, aquatic plants and algae such as seaweed, aquatic products used as animal feed, and synthetic alternatives to aquatic products (e.g. from cellular agriculture).

This book reviews the environmental impacts of livestock production, covering life cycle assessment, livestock’s contributions to greenhouse gas emissions including methane, the impacts of pig and sheep production, and strategies for improving the environmental performance of intensive poultry production.

This book examines the relationship between capitalism and the commons. Table readers may be particularly interested in the book’s discussion of agricultural land ownership and squatting, agroecological networks in Colombia, and women’s access to land in Africa.

This book argues that transitioning from today’s industrial food system towards a more sustainable system requires cultural shifts. The author draws inspiration from themes in the Homeric epics to propose a new environmental governance model based on “eco‐states responsible for agroecological management”.

This article in The Atlantic explores the role that phosphorus - long thought to be a limiting factor in the productivity of the biosphere - plays in the food system. Phosphorus fertiliser has historically come from bones, phosphate rock deposits and human waste. Today, while there are fears of a shortage of mined phosphorus, phosphorus runoff also pollutes water and harms aquatic ecosystems. Companies are now trying to close the phosphorus loop by recovering the fertiliser from human sewage and animal waste.

In this blog post, published by the Resilience of the UK Food System in a Global Context research programme, Dr John Ingram of the University of Oxford’s Environmental Change Institute argues that, contrary to public perceptions, the Australian food system is at growing risk of disruption from droughts, floods, an aging farmer population, or potential shocks such as a reduced ability to export beef to China due to bluetongue disease.
