Maasai pastoralists are calling for international support to stop the Tanzanian government's plans to evict thousands of people from their ancestral lands in Ngorongoro and Loliondo to make way for tourism, development and wildlife hunting. In a public letter, Maasai community leaders argue that the Tanzanian government is falsely blaming livestock grazing and population growth for environmental degradation, to justify the mass evictions.

Using European case studies, this book examines how knowledge about food is transmitted and circulated by a wide range of actors, including textbooks, the press, cookery classes, social media, bloggers, marketers, and so on.

This report from Friends of Ocean Action, FishWise, Global Fishing Watch and the Stanford Center for Ocean Solutions discusses how seafood providers can use data to avoid illegal, unregulated or unreported fishing. It describes the first phase of the development of a “Supply Chain Risk Tool” that gathers data on fishing fleets and vessels from multiple sources and identifies potential risks.

In this policy brief, the Food Research Collaboration summarises points relevant to food and diet in the Intergovernmental Panel on Climate Change’s Working Group 3 report, published in April 2022. The summary notes that both individual and policy-level choices about food are highly relevant to climate change and could make significant contributions to climate mitigation; that action is required on both consumption and production; that demand-side interventions can have beneficial effects for health; that individual action alone is not sufficient; and that “choice architecture” can influence demand patterns.

The UK’s National Food Strategy brought the term “agroecology” into mainstream policy discussions. This policy insight from the Food Research Collaboration traces how different definitions of the term have evolved, with varying degrees of emphasis on agroecology’s agricultural practices and political aims. The National Food Strategy defines agroecology mostly in terms of on-farm activities, rather than as inherently interlinked with wider food system shifts.

This report from IPES Food explores the factors underlying the increase in global food prices, which in April 2022 were 34% higher than a year previously. It focuses on the impacts of the Russian invasion of Ukraine as well as broader structural issues in the global food system, including heavy reliance on food imports, barriers to changes in production systems, excessive speculation in grain markets, and vicious cycles of climate change, poverty, conflict and food insecurity.

Developed economies such as the UK, Germany and Japan could suffer the greatest economic losses from sudden declines in pollinator populations, due to their dependence on imported crops, according to this modelling study. The paper estimates the changes in production levels and market prices that would occur for 74 animal-pollinated crops following sudden pollinator loss due to three causes: high use of pesticides; natural disasters such as drought; or countries being unable to pursue sustainable agricultural policies due to high levels of debt.

Enhanced rock weathering (ERW) on UK cropland, i.e. adding crushed rocks to soils (read more about the process here), could sequester 6–30 MtCO2 yr−1 by 2050, providing up to 45% of the atmospheric carbon removal necessary to reach national net zero goals. ERW can also reduce nitrous oxide emissions from soils, reduce soil acidification (through formation of carbonate) and reduce fertiliser requirements (by increasing supply of phosphorus and potassium). The paper questions the need for energy-intensive milling of rocks into fine particles, finding that particles on sites with high weathering potential are weathered rapidly regardless of size.

This paper explores how people’s moral views towards different animals change between childhood and adulthood. Based on surveys with participants in the UK, children were found to be less likely than adults to show speciesism (defined as assigning moral worth to beings based on their species), less likely to categorise farm animals as food as opposed to as pets, more likely to think farm animals should be treated better (than adults would treat them), and less likely to think it is morally acceptable to eat meat or animal products. The authors hypothesise that people learn to reconcile inner moral conflicts about eating animal products by forming a hierarchy in which some animals are given a lower moral standing.
