Can Oreo cookies be sustainable?

We are seeing intense pressure on food companies to adopt more sustainable supply-chain and production practices.  But can an ultra-processed food ever be sustainably produced?  Or, is a sustainable snack food an oxymoron?

In BakeryandSnacks.com’s Spotlight on Sustainability, snack food companies say what they are doing to reduce their impact on the environment:

Global Meat News on this industry’s sustainability problem

The meat industry is under siege these days over issues of sustainability.  The major recommendation of the EAT-Lancet report is to cut consumption of red meat by half in order to reduce greenhouse gas emissions.  This is a worry for the meat industry.

This collection of articles indicates how this industry is dealing with the sustainability issue—in some cases, with difficulty, denial, and fighting back.

GlobalMeatNews.com, an industry newsletter, has this Special Edition: Sustainability

In this special edition on sustainability, we look at what the major players in the international meat industry are doing to ensure the future of the sector. We start with quality control plans with Brazilian poultry as well as a massive investment in solar technology by Hormel Foods. We also look at Cargill’s work on reducing antibiotics and a new beef scheme in Ireland.

Weekend reading: Science Breakthroughs for Agriculture

The National Academies of Science, Engineering, and Medicine has a new report out on Science Breakthroughs to Advance Food and Agricultural Research by 2030.

In the next decade, the major goals for food and agricultural research include (1) improving the efficiency of food and agricultural systems, (2) increasing the sustainability of agriculture, and (3) increasing the resiliency of agricultural systems to adapt to rapid changes and extreme conditions.

To that end, the committee that wrote this report examined “breakthrough opportunities that could dramatically increase the capabilities of food and agricultural science.”

The breakthroughs?

  1. A systems approach to understand the nature of interactions among the different elements of the food and agricultural system can be leveraged to increase overall system efficiency, resilience, and sustainability.
  2. The development and validation of precise, accurate, field-deployable sensors and biosensors will enable rapid detection and monitoring capabilities across various food and agricultural disciplines.
  3. The application and integration of data science, software tools, and systems models will enable advanced analytics for managing the food and agricultural system.
  4. The ability to carry out routine gene editing of agriculturally important organisms will allow for precise and rapid improvement of traits important for productivity and quality.
  5. Understand the relevance of the microbiome to agriculture and harness this knowledge to improve crop production, transform feed efficiency, and increase resilience to stress and disease.

I’m worried about how all this will help make agricultural production more sustainable.  For that, we need smaller scale, fewer chemical inputs, crop rotations, and other such methods.  I wish NASEM would do a serious study on agricultural sustainability.

Update, May 26: Benjamin Chaulet has translated this into French and posted it on his blog, nutrition-newage.com. Here is a pdf.

Weekend reading: The Lancet / EAT Forum report on healthy and sustainable diets

I’ve saved this for Weekend Reading because it will take a weekend to get through it.  The report is a blockbuster: 37 authors, 47 pages, 357 references.

The Lancet commissioned this report from the EAT Forum, which brought together international experts on diet and health (most of whom I do not know) to define unifying dietary principles that best promote will promote the health of people and the planet.

Fortunately, the diet that is best for health is the same diet as is best for the planet.  The report defines it on page 5.

To summarize:

This report has many strengths:

  • It is researched in depth and is now the reference source for information about needed dietary changes.
  • It firmly links dietary health to environmental sustainability.
  • Its findings are consistent with many previous reports on diet and health, including that of the 2015 Dietary Guidelines Advisory Committee DGAC).
  • Its messages are unambiguous.
  • The summary report is a big help
  • The timing  is excellent; the 2020 Dietary Guidelines advisory committee, if it ever gets appointed, will have to pay close attention to the science reviewed in this report.
  • It focuses on food, not nutrients (these meals meet the standards of recommended diets).

Does this report settle the questions?  Hardly.  Remember the fuss over sustainability (the “S-word?”) in the 2015 report of the DGAC?

There is lots to read and think about here.  Enjoy!

Weekend reading: A view of how to feed the world sustainably

The World Resources Institute has a new report on how to feed the world in a way that is sustainable.

The report is based on the premise that 56% more food will be needed by 2050.  Given that premise, the unavailability of more land on which to grow food, and the need to mitigate greenhouse gases, the report recommends (among other things) increasing the efficiency of production and managing demand.

I’d like to see some careful evaluations of the basic premise of this report as well as its recommendations, which seem to place a large burden on individuals rather than governments or corporations.  The word “corporation” does not appear in the report; food companies come up only in the context of food waste (a non-controversial issue):

Indexes: Ranking Systems for Sustainability and Nutrition

Two new Index Systems rank countries for sustainability and corporations for promoting health.

I.  Sustainability Index.

The Economist and Barilla have devised a new, interactive Index that ranks countries on the basis of food loss and waste, sustainable agriculture, and the ability to meet nutritional challenges.  Its scoring system goes from 0 (terrible) to 100 (perfect).

The top ten scoring countries are:

None of the scores is exemplary.  The US rank is #26.

II.  Access to Nutrition Index

The Access to Nutrition Foundation (Netherlands) ranks corporations on their strategies, policies, and actions to address obesity and diet-related diseases in the US.

The overall rankings, shown here, are relatively low.  Some do better than others on governance, products, accessibility, marketing, lifestyles, labeling, and engagement.

The highest scores are for labeling.  The lowest scores are for accessibility.

Indexes like these are useful for understanding where we are.  They should inspire us to action.

Principles for responsible international investment in food and agriculture

The Committee on World Food Security of the UN’s Food and Agriculture Organization has a report out on this topic, well worth pondering.

 

Sustainability, respect, safety, health, transparency, accountability—all good ideas.  The trick is to put them into practice.

Reports about sustainable and local farming: one after another

Sustainable Food Trust has a report on a conference on the True Cost of American Food.

Health is the obvious cost, but others include:

  • the cost of nitrate and pesticide pollution of ground and river water from agro-chemicals, which in some areas of the US are so high that the water industry is struggling to provide drinking water within legal limits,
  • air pollution from CAFOs shown to be increasing respiratory infections and other diseases in people living nearby,
  • the loss of biodiversity, including the decline of farmland birds and pollinating insects,
  • soil degradation and erosion from continuous monoculture crop production,
  • the human health costs to employees working in stressful conditions in food processing plants.

The American Farmland Trust and Growing Food Connections have published GROWING LOCAL: A Community Guide to Planning for Agriculture and Food Systems.

This is an enormously useful how-to guide to developing local food systems with lots of facts and figures .  Here is an example:

The Federal Reserve Bank of St Louis , of all things, has issued “Harvesting Opportunity: The Power of Regional Food System Investments to Transform Communities.”

Harvesting Opportunity…highlights models for collaboration between policymakers, practitioners and the financial community, and discusses research, policy and resource gaps that, if addressed, might contribute to the success of regional food systems strategies.

New Food Economy has an analysis by Katy Kieffer on who really owns America’s farmland

While urban commercial real estate has skyrocketed in places like New York, San Francisco, and Washington, D.C., powerful investors have also sought to turn a profit by investing in the most valuable rural real estate: farmland. It’s a trend that’s driving up costs up for the people who grow our food, and—slowly—it’s started to change the economics of American agriculture.
