Knowledge for better food systems

Showing results for: Theory, methods and tools

There are different ways to analyse and evaluate impacts from food production and consumption. This section highlights papers that introduce specific methodologies, tools and theories that can be used as a guide or reference when developing a research or policy approach.

Fishers increase their fishing activity prior to the establishment of a new marine reserve, a new paper claims. The study used satellite data to study one particular marine reserve, the Phoenix Islands Protected Area (PIPA). While fishing effort dropped to almost zero after the marine reserve was established, fishing effort prior to the reserve’s establishment was 130% higher than in a control region (where no reserve was planned).

The EU-funded CAPSELLA project, which develops digital tools for agrobiodiversity, has released an online tool to guide users through the steps of taking a “spade test” to monitor soil quality. Users can also choose to upload their results to a public database.

This book, by Jonathan Coppess, explores the history of agricultural policies in the United States.

This book, written by the Barilla Center for Food & Nutrition and edited by Danielle Nierenberg of Food Tank, discusses how the global food system can produce sustainable, healthy food for everyone. Topics include soil degradation, water use, barriers to accessing food, corporate influence on dietary choices, and food waste.

The Adam Smith Institute, a UK-based free-market think tank, has published a briefing paper in which it argues in favour of lab-grown meat (also known as cultured meat). The authors say that the potentially lower land use of lab-grown meat, compared to conventional meat, could allow some farmland to be rewilded, managed in less intensive ways, or used to build more houses.

A recent paper uses data from three countries (Ghana, Mexico and Poland) to determine whether more carbon can be kept in above-ground stocks by land sparing (increasing farms yields to minimise the conversion of natural habitats to farmland) or land sharing (increasing carbon stocks on farms, at the cost of converting more natural habitat to farmland because of lower yields). Land sparing maintained the highest above-ground carbon stocks in all cases studied.

Alcohol production, packaging and transport in Sweden has a carbon footprint of 52 kg CO2 eq. per person and accounts for around 3% of dietary emissions, according to a new paper by FCRN member Elinor Hallström. Per litre of beverage, wine, strong wine and liquor have higher carbon footprints than beer. This study does not include emissions from retail or consumer activities.

A recent paper argues that the global food system needs to become both more sustainable and more resilient to environmental and economic shocks. Defining resilience as “the resistance or rapid recovery of system interrelationships and functions after perturbation”, the paper points to existing examples of “undesirable” resilience, which inhibit the transformation of the food system to a more sustainable state.

A carbon tax applied across the whole economy, including agriculture, could put more people at risk of hunger (in terms of dietary energy availability) than climate change itself, according to a recent paper.

Researchers from the University of Oxford’s Environmental Change Institute (of which the FCRN is part) have created a new tool - the “temperature of equivalence” - to map the impacts of varying degrees of climate change in different areas. They find that people living in low-income countries will, on average, experience heat extremes at 1.5°C of (global average) warming that people living high-income countries will not encounter until 3°C. This result is based on combining a map of predicted heat extremes with information on where people actually live within these areas. The paper also finds that, on average, people in high-income countries would experience the same increase in extreme rainfall after 1.0°C of warming that people in low-income countries would experience at 1.5°C of warming.

A group of researchers from the University of Michigan’s Sustainable Food Systems Initiative has called for a new approach to solving food system problems, based on the intersection of four key areas: the ecology of agroecosystems, equity on a global and local scale, cultural dimensions of food and agriculture, and human health.

A new paper finds that the global marine fishing fleet produces greenhouse gas emissions equivalent to 4% of the total emissions from global food production. The types of fisheries with the highest emissions intensity per unit of catch are those using motorised craft (vs. non-motorised), those harvesting for human consumption (vs. catches used for meal, oil or non-food uses), fishing for crustaceans (vs. other species types) and fisheries in China (vs. those in other regions).

This book, by Ray A. Goldberg, provides the perspectives of people involved in shaping the global food system, including leaders in academia, nonprofits, public health, and the private and public sectors.

Managing tropical forest conservation on the basis of maximising carbon storage might not protect the most biodiverse regions of forest, according to a recent paper. Using datasets from Brazil, the authors found that the correlation between biodiversity and levels of carbon stored in forests depended on whether and how the forest had been disturbed by human activity.

Irish social enterprise foodture has produced a podcast about food citizenship, featuring Anna Cura of the Food Ethics Council. Anna describes the concept of food citizenship as being a mindset where people to think about themselves as engaged citizens, not just consumers, when making food purchase choices.

The US divisions of Danone, Mars, Nestle and Unilever have established the new Sustainable Food Policy Alliance, hoping to influence policymakers and regulators in five key areas: product transparency, nutrition, the environment, food safety and a positive workplace for food and agriculture workers. According to the Washington Post, the new alliance supports the reduction of salt in packaged foods and the introduction of “nutrition facts panels” to highlight sugar and calorie information (read more here).
