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.

Over half a million acres of irrigated farmland may have to be permanently taken out of agricultural use in the San Joaquin valley in California in order to conserve groundwater, according to this report by the non-profit Public Policy Institute of California. The report suggests using the land for generating solar energy, restoring ecosystems or managing flood risk by restoring floodplains.

The UK Government has released a summary of the likely impacts on business and trade if the UK leaves the European Union without a withdrawal agreement on 29 March 2019 (i.e. a ‘no deal’ Brexit). Several items are relevant to the food system. See also the draft of temporary rates of customs duty on imports that will apply to different goods in the event of a no deal Brexit.

In this latest instalment of the Food Brexit Briefings series by the UK’s Food Research Collaboration, the authors argue that the UK’s upcoming departure from the European Union presents an opportunity for Wales to reform its food and farming system, making use of both grassroots food initiatives and new legislation.

This paper analyses how different agriculture and forestry activities affect biodiversity and carbon sequestration. In 2011, the top driver of losses to bird species richness was cattle production, while the greatest driver of losses to net carbon sequestration (relative to sequestration if natural vegetation were allowed to grow) was forestry.

The UK’s Department for Work and Pensions will introduce a new measure of food insecurity, reports the Guardian. The new measure will be based on ten questions about food purchase and consumption patterns in the annual Family Resources Survey, which surveys around 20,000 households each year.

In this report, the UK think tank Green Alliance argues that land-based carbon credits could be incorporated into a ‘Natural Infrastructure Scheme’ (NIS), a scheme previously proposed by the Green Alliance.

Research literature, policy indicators, and assessment tools use many different variables to assess sustainable agricultural land systems in Europe (for example soil loss, landscape diversity and food quality). Out of 239 of these variables identified in this paper, 32 have been covered by all three perspectives (i.e. research, policy and practice) while the remainder have only been considered by one or two perspectives.

The 2019 Green Alliance Annual Debate discusses the ways in which earth observation and data science can improve our understanding of and ability to address environmental issues - for example, monitoring deforestation or water levels in reservoirs in real time through satellite images.

This commentary from the US-based Breakthrough Institute argues that agroecology is not the best way of reforming agriculture in Africa, because most African agriculture already follows agroecological principles such as avoiding monocropping and not using much fertiliser or pesticide.

The UK’s Food and Drink Federation (FDF) has published its 2018 environmental progress report. FDF members report a 53% reduction in their greenhouse gas emissions from energy use in manufacturing operations since 1990, and a 39% reduction in water consumption since 2008.

This paper, by John Lynch of the University of Oxford’s LEAP project, finds that carbon footprint studies of beef cattle typically do not report separate values for emissions of different greenhouse gases such as methane and nitrous oxide. Instead, studies generally report only an aggregated figure in the form of the 100-year Global Warming Potential (GWP100) as CO2-equivalent.

This paper, by researchers from the University of Oxford’s LEAP project, models the climate impacts of beef cattle and cultured meat over the next 1000 years using a climate model that treats carbon dioxide, methane and nitrous oxide separately, instead of using the widespread Global Warming Potential, which assigns a CO2-equivalent value to each greenhouse gas according to warming caused over a specified timeframe.​

This book, by William D. Schanbacher, addresses ethical issues around access to food, outlines how the global food system works, and offers suggestions on how people can engage their communities and learn more about the foods they eat.

This report from IPES Food argues for a new approach to governing food systems in Europe, where sustainability goals are integrated across policies for different sectors, including agriculture, trade, food safety, environment and research.
