Overarching Trends
Labeling concerns: COOL, GMs, Animal Welfare, Fair Trade, Certified Organic, etc, etc, etc…
Corporate or government leadership: shifting perspectives?
Inter- and intra-connectedness of agricultural crises
None of these issues can be discussed without understanding the role of the global food business and the agricultural supply chain
Labeling
Underlies a fundamental division in US-EU practices: consumer right-to-know vs. agency stamp of approval
Labeling is often the preferred mechanism of control for industry groups, but it does not address a core problem: that environmental concern expressed in polls and elsewhere often does not translate into behavior in terms of “willingness to pay” (WTP)
The Rise of CSR in the Food Business
Why does this matter? 10 companies produce 40%
of all the food we buy (and 40 companies produce 85%)
20-30% of product value comes from the farm – the rest is food industry-value added
General trend towards corporate-environmental alliances IKEA and Rainforest
Alliance/WWF/FSC Marriott and Conservation
International Myriad examples exist: water,
labor, health, animal welfare, …
Agricultural Biotechnology:Evaluating the two competing narratives
Fifteen years in: the first transgenic crops were planted in 1996 (1st to be developed was Calgene’s Flavr Savr tomato, developed in 1989)
Key lesson: barring allergenicity and the risk of antibiotic resistance, GM foods are probably safe and healthy for human consumption; the real risk is how their use fosters the uncritical acceptance of conventional agriculture generally and large-scale monocropping in particular
The Good Things (Biotech as Technofix)
Decreased total pesticide usage Especially valuable in developing
countries, where lax or nonexistent regulation encourages pesticide companies to export their products that are banned in the US/EU
Higher yields in easy to understand monocropped systems can (arguably) produce more food on less land
Only 10% of the world’s land surface is arable, and much of it is already overfarmed and on eroded soil
Has the potential to help with diseases and nutrition deficiencies that are systemic in much of the developing world
“Phytoremediation”, whereby plants detoxify pollutants in the soil or absorb and accumulate polluting substances out of the soil
May enable the development of more efficient grains for animal feed
Genomic mapping leads to further food safety opportunities
The Bad Things (Biotech as Frankenfood)
Agricultural biodiversity plummeting (hence the Svalbard Global Seed Vault…) From 40,000 rice strains in India to
250 Small farmers become entirely
dependent upon corporate seeds (terminator technology)
Non-GMO seed producers suffer from crop contamination
Consumers lose right to choose (under US system, at least)
Works hand-in-hand with monocropping, stymieing polycultures “ecological theory predicts that as
long as transgenic crops follow closely the pesticide paradigm prevalent in modern agriculture, such biotechnological products will do nothing but reinforce the pesticide treadmill in agroecosystems”
The StarLink Debacle, circa 2000
StarLink corn approved for animal feed only (the largest US market for corn) due to potential human allergenicity, but found its way into a Taco Bell taco shells
Raised serious questions about segregation, traceability (required 660-foot buffer zone), and allergenicity Subsequent FAO/WHO standards
(2001) acknowledged the near impossibility of zero allergenicity risk due to the inability to prove a negative
Functional (and Pharma-) Foods
A functional food is technically any food with health-promoting claims or abilities (Marketing) example: yogurt
In the GM context: Golden Rice (rice with higher
carotenoid levels) Crops enriched with Vitamin E,
folate, high protein content in the form of Lysine
Hypoallergenic soy and rice exist, and wheat is being developed
“Pharma” foods are being developed that may help prevent or cure diseases such as cholera and diarrhea
What are the drawbacks
A potential contributor to increased pest resistance and the development of ‘superbugs’
Opposed on GM grounds Viewing food solely as the sum of
their micronutrients robs them of their ‘whole food’ value (=Pollan’s critique of nutritionists)
Evidence of nutrient uptake is unclear Corn/lime Mayan nixtamalization
example Positive example from Dartmouth
researchers re. higher-calcium carrots
Pharm Animals
In February 2009, the FDA ruled “safe” a herd of goats containing ATryn, an intravenous anti-clotting drug extracted from their milk for a fraction of the pharmaceutical’s production price. These goats are the first such GM animal to be approved in the US. ATryn is the brand name of
‘anticoagulant antithrombin’ as manufactured by Massachusetts-based GTC Biotheraputics
Although groups like the Humane Society of the United States (HSUS) oppose GM animals on principle because of their mechanistic nature, there have been no animal-welfare related harms associated with ATryn to date
“Hardier” Crops CEO of Performance Plants
Incorporated said in 2008 that drought resistant oilseed rape and maize will be on the market “in four years”
“Snorkel rice” takes the ‘snorkel’ genes in flood-tolerant rice and introduces them to higher-yield rice
Crops able to grow with less water or in conditions of high salinity have been “in the pipeline” for the last decade, with little tangible gain (such as Water Efficient Maize for Africa (WEMA) Hugh Grant, Monsanto’s CEO,
acknowledged when talking to an HBS class of mine that it was probably a PR mistake on the company’s part to focus solely on proprietary crops (Bt/RoundUp) at the expense of ‘humanitarian’ technologies
Innovations in Crop Agriculture
New (non-soy) sources of protein synthesis Algae Grain crops In vitro meat Leaf protein extraction Mycofungi lupins
The marketability of non-transgenic but biotech ‘borderline’ methods to GM-skeptical audiences (best example: hybrid corn in the 1920s) Seed coating marker-assisted breeding Genomic selection
Other innovations: Controlled release fertilizers
Algae
Like in vitro meat, Algae is hampered by the “yuck” factor
While distinct from algal biofuel, food algae could be a potential co-product of fuel algae
The biggest recent player in the fuel algae game is Exxon Mobile, who partnered with Synthetic Genomics Inc. in July 2009 to invest $600 million in Algal fuels
Up with cellulosic ethanol as an in process technology rather than an existing one – seems to me like it needs much more attention. Algae has the added advantage of being able to capture fertilizer runoff, thus potentially preventing oceanic eutrophication
Has the added advantage of possibly creating food as a co-product of fuel, most likely for animal feed in the form of pellets
Seed Coating
LandecAg’s intellicoat (above) “... is an agricultural technology company
that specializes in temperature-activated seed coatings.”
PlantTech’s agristrike (below) “PlantTech is the largest Australian field
crop, canola and pasture Seed Company, with an unsurpassed product range of leading proprietary cereal, oilseed, pasture, pulse and forage varieties, plus access to a comprehensive range of public varieties.”
Other developments of note: Plant Health Care Inc.’s Myconate and Harpins technology (see ppt in notes)
Lesson: neither of these companies appear at all green, but the technology does have various potential green applications.
“It can greatly reduce insect pest, protect the environment, save the seeds (about 1/3 seeds), increase the output of crops (increase by 10-40%) and promote the development of seeds project. “
Genomic Selection Using genomic selection for marker-
assisted breeding, crop and animal breeders can select desirable alleles without actual gene splicing
"some of the most potent objection to transgenics actually has to do with the increase in market power that went along with some of the input companies. Genomic selection and marker-assisted breeding have exactly the same kind of economic power implications, if no more so, as transgenics. People who are upset about transgenics but think marker-assisted breeding is okay are just incredibly naive." Paul Thompson (U. of Michigan), in a
phone interview
Aquaculture and Fisheries
-Key Lesson: the barriers to international cooperation on sustainable fisheries, and the high substitutability of consumer preferences for fish products, indicates that the most short-term progress can be made in improving fish farming practices, especially in China (with many caveats…).
Global Fisheries Crisis On current course,
collapse of all major fisheries by 2050. (Science, Nov. 8)
Tragedy of the commons / collective action problem (the regulators want to support their fishermen—they don’t get elected by cutting back)
The problem of bycatch
Growing appetites• Shark Finning
example
Capture Fisheries
Divisible by fishing area, gear and the main target species North Sea herring purse seine
fishery Gulf of Mexico shrimp trawl fishery southern ocean Patagonian
toothfish longline fishery. Some gear and species are
inherently more unsustainable than others Bottom trawling Very long-lived species
Bycatch and Bottom Trawling
Bycatch Wild-caught shrimp catches up to 10 pounds of
discarded sea life for every pound of shrimp All major fisheries catch large amounts of
bycatch, whether trawl, purse seine, or longline.
The problem is especially bad in illegal, unreported and unregulated (IUU) fisheries in developing countries
Bottom Trawling The image to the right is of the “Gulf of Mexico,
captured by the Landsat satellite in late 1999, [which] shows the sediment trails left behind by individual ships (the bright spots) - a testament to the utter devastation the practice exerts on vast seafloor ecosystems.”
A case study in collapse
The North Atlantic Cod fishery has collapsed precipitously
The solution (would have been): honest assessment “maximum sustainable yield” with proper enforcement
The Insidious Role of Branding
Thanks to clever marketing, previously unpalatable fishes are becoming desirable delicacies which are fished (often illegally) using ecologically devastating bottom trawling methods.
Which sounds better: Orange roughy, or
slimefish? Chilean Sea Bass, or
Patagonian toothfish?
The Need for Intergovernmental Oversight
Fish tend not to care about 15-mile territorial waters or 200 mile Exclusive Economic Zones (EEZs) as established by the 1982 UN Convention on the Law of the Sea (UNCLOS). This makes transboundary intergovernmental oversight a must
64% of the world’s ocean is international waters; of that, 3/4ths is unmanaged
“In 1995 there were more than 1.2 million decked fishing vessels in the world, up from just fewer than 600,000 in 1970.”
much of this growth is government subsidized, which results in excess capacity and thus low margins for industry fishermen, who then have incentives to fish more.
Marine Stewardship Council Founded in 1996 as Unilever/WWF collaboration
Founding mission: “…to work for sustainable marine fisheries by promoting responsible, environmentally appropriate, socially beneficial and economically viable fisheries practices, while maintaining the biodiversity, productivity, and ecological processes of the marine environment.”
(Relative) success stories ‘Dolphin-safe” tuna “Give Swordfish a Break” Campaign pledge Wild Alaskan salmon fisheries certification
Unlike the issue-specific and tangible cases of dolphins and swordfish, however, the MSC eco-label covers fish ranging from frozen cod in Britain to Alaskan Salmon to a range of other regulated marine capture fisheries as of October 2008, there are nearly 2,000
seafood products with the MSC’s seal of approval
The Keys to Sustainable Wild Caught
As the MSC and other cases indicate, the problem isn’t that people don’t know how to work towards sustainable fisheries. Barring a lack of scientific knowledge about the sea (‘out of sight, out of mind…’), they do. The problem, rather is a lack of political will and legal authority combined with a collective action problem relating to an exhaustible public good
That said, these are the things that work: restrictions on gear like nets so that
smaller, younger fish can escape limits on the total allowable catch
(although maximum sustainable yield can be very hard to determine – Alaskan Pollock and NMFS ex.)
closing some areas to fishing certifying fisheries as sustainable offering shares of the total allowable
catch to each person who fishes in a specified area.
Work with existing national and international legal jurisdictions to maximize utility
Growth of Aquaculture
Key lesson: for better or for worse, aquaculture is the only way to prevent oceanic collapse barring a decline in demand for seafood (which doesn’t look likely). The logical conclusion is to make sure fish farming is done as well as possible.
Why ‘especially in China’?
Why Tilapia?
Large size, rapid growth, omnivorous diet, high stocking density tolerance, no planktonic phase
GIFT Tilapia
“GIFT, or Genetically Improved Farmed Tilapia, grows 60 per cent faster and has a 50 per cent higher survival rate to adulthood than the original fish. Sometimes also known as the Super Tilapia, the fish was developed through vigorous selection-breeding programs -- the first time a tropical food fish has been improved using such methods. The fish used to breed GIFT was the Nile tilapia (Oreochromis niloticus).”
HQ Sustainable Maritime Industries
Exports tilapia to US, Korea, Japan, and Mexico from its facilities in Hainan, China Mission statement
• To bring quality to every aspect of HQ's vertically integrated aquatic products business.
• To lead China in penetrating world seafood markets.
• Increase profitability through the introduction of zero-toxin products while respecting the environment and communities in which it works.
Best Aquaculture Practices Certified (potentially problematic – see next slide – but is currently the only major standards-setting organization for aquaculture
Best Aquaculture Practices Implemented by the Aquaculture Certification
Council (ACC) of the Global Aquaculture Alliance (GAA)
The ACC is a “process” certification currently certifies shrimp hatcheries, shrimp, tilapia and channel catfish farms and seafood processing plants to include shrimp, channel catfish and tilapia.
Although ostensibly independent, the GAA is effectively an industry consortium. According to Food and Water Watch, “Their process combines annual site inspections and effluent sampling, but allows for certain use of antibiotics and chemicals. Although GAA’s standards are more measurable than most others, they have received criticism from several organizations, including the Mangrove Action Project and Environmental Justice Foundation, for flawed standards that fail to adequately protect mangrove ecosystems.”
Examples of conflicting preferences: organic fish and ‘sustainable’ tuna
Whereas fish feed is usually 50% fishmeal (which can be made from unsold fish and fish offal, or small whole fish) and 50% grain, organic salmon must use fishmeal from sustainable fisheries intended for human consumption.
Clean Seas Tuna, Ltd. is trying to breed southern bluefin tuna, which is being massively overfished to satisfy demand for fatty tuna in sushi. They are also developing wheat pellets to feed their marine-caged tuna. This is a ‘stopgap’ measure in the sense that it is responding to market demand rather than trying to reshape demand.
Marine or Freshwater Aquaculture?
Harder to regulate generally than freshwater aquaculture
More likely to cause disease transference to wild species
However, some species can only be farmed in marine systems
Freshwater aquaculture is generally better than marine aquaculture, as most of the fish raised are herbivorous (carp, tilapia)
Organic Shrimp Shrimp is the most popular seafood in the US
Shrimp farming destroys up to 30% of the world’s coastal coastal mangrove forests
It requires 2 lbs of fishmeal and squid to yield one lb of shrimp
EcoCamaronera Bahia—the world’s first certified organic shrimp farm—practices mangrove-friendly methods in Ecuador, as does Biocentinela.
Like all shrimpers in Ecuador, both are at heavy risk for white spot disease
OceanBoy farms is an inland marine shrimp farm in Florida that has ACC organic shrimp certification and USDA organic seafood certification (the first to get it).
They have a very high ration of shrimp per foot, but they pump in extra oxygen and clean the water frequently. There is a higher risk for disease if poorly managed, but is otherwise a fruitful model
The Role of GM Fish: AquAdvantage Salmon
AquAdvantage® salmon, developed by Aqua Bounty Farms
“Aqua Bounty is developing advanced-hybrid salmon, trout, and tilapia designed to grow faster than traditional fish. AquAdvantage® Salmon (AAS) reach market size twice as fast as traditional salmon. This advancement provides a compelling economic benefit to farmers (reduced growing cycle) as well as enhancing the economic viability of inland operations, thereby diminishing the need for ocean pens. AAS are also reproductively sterile, which eliminates the threat of interbreeding amongst themselves or with native populations, a major recent concern”
The company has spent more than a decade chasing regulatory approval from the FDA, but FDA officials have reportedly said it is coming “soon”, especially in light of the recent “pharmed” goats ruling.
Solutions (Aquaculture)
Greater independence for certification bodies The largest certification body to date, the Global
Aquaculture Alliance’s Best Aquaculture Practices, is probably too caught up with fishing interests to provide a neutral assessment of environmental and other impacts
Supporting feed inputs other than wild-caught fishmeal “Ento-protein” progress by Neptune Industries
using insects rather than fish to provide feed protein—the company itself, however, may be a poor investment
Algae pellets
Traditional Chinese aquaculture (4,000 years old) Rears herbivorous and carnivorous species in the
same pond using plants to serve as food (eliminates fishmeal and is ecosystem-based approach: “integrated multi-trophic aquaculture”).
This model can also use ducks/chickens in an integrated system where their poop makes algae for the fish to eat (so that you only have to feed the chickens and you get two crops) – but not done on a large scale
Solutions (Consumer)
Support: farmed herbivorous species
consumption: tilapia, bream, carp and catfish with BAP certification or (better yet) Monterey Bay Aquarium Seafood Watch approval
• Ex) the 2009 Northeast Seafood watch endorses US farmed tilapia as ‘best choices’, South American farmed tilapia as ‘good alternatives’, and Asian farmed tilapia as ‘to avoid
small marine capture species consumption: sardines, anchovies, mackerel, herring, etc.
Reputable certified wild carnivorous fish
Impediments
Tight profit margins are not easily amenable to large scale modification of practices, creating disincentives to change towards more sustainable programs (or, as one of my professors said, “the numbers tend to cut down your options”
The sustainable fish are often not the much-touted Omega 3-rich fish (they are, however, lower down the food chain and are thus lower in PCB and Mercury contamination levels).
The nature of global fisheries oversight is a classic case of market failure, with overfishing causing some sectors to go through a Hubbert curve not unlike that of peak oil.
In many cases, the demand for seafood is voracious and indiscriminate, particularly in the Chinese delicacy market
Animal Agriculture
Types of Concerns Environmental Labor Practices Human Health Animal Welfare
A Ridiculously Short History of Conventional Agriculture
The Haber-Bosch Nitrogen fixing process quintuples the available ammonia supply for crops in 1909 Dramatically changes the global
Nitrogen cycle, which is only beginning to be properly understood
To make a long story short: leftover munitions and biological agents (i.e., nitrogen and phosphorous) after WWII become fertilizer and pest/herbicides, which along with govt. crop subsidies make CAFOs economically viable
Earl Butz appointed Secretary of Agriculture by Nixon: “get big or get out”
Vertical integration, economies of scale, and globally provisioned supply chains (following market liberalization)
The Livestock Revolution
A structural change, termed the “livestock revolution”, is taking place around the world but with particular intensity in East Asia Multinational supermarket and fast
food chain expansion creates demand for streamlined intensive meat production
The availability of cheap course grain on international markets has increased the global CAFO focus on monogastric animals like chicken and hogs
At current rates, Global meat/milk demand to double within 50 years
80% of current growth in industrial systems
Developing countries overtook developed countries in meat production in 1996
Niman Ranch: a case study in the problematic economics of ‘happy meat’
The original provider of humane meat to Chipotle Market Grill
Bill Niman was forced to sell his share in Natural Food Holdings LLC, and he now boycotts Niman Ranch for their transport to slaughter and microbial use policies
The net effect: until a consumer market exists that is willing to capture the various extra costs of humane meat, it won’t be profitable in the US
Solutions
As with crop biotech, the ‘solutions’ fall into two categories: those that address Berry’s original concern (fundamental solutions), and those that work within the confines of ‘conventional’ agriculture (stopgap solutions). Both should be applauded, especially if fundamental change appears unlikely, but in the long term technofixes are unlikely to solve many of the food industry’s systemic environmental problems.
Solutions can be further subdivided into governmental (and intergovernmental) solutions, producer solutions, and consumer solutions
Stopgap solutions
Animal ag solution: Define CAFOs as point sources
under the CWA (in process – see law blog link)
Carbon solution: Changing animals’ feed or
developing transgenic animals that ‘fart/burp less or better’
• ex: adding 2% fish oil to cows’ feed may reduce methane emissions by 20%
Aquaculture solution: Breeding tuna
Eutrophication solution Controlled-release fertilizers
Biotech solution: Drought-resistant GM crops
Fundamental Solutions
Changing our diets Understanding how the second
law of thermodynamics should impact our food choices
Changing farm policy at national levels In the US, ending commodity
support for corn and soy and prioritizing sustainable fruit and vegetable growth
Internationally, greater collaboration and focus on population, understanding the oceans, and IP reform (this list could go on and on)
Recap of Key Lessons
Biotech GM foods are probably here to stay, but
global agriculture still requires a paradigm shift to become truly sustainable
Fisheries/Aquaculture Aquaculture needs an independent
ecolabeling and certification organization like that of the MSC to supplement the industry-influenced GAA
A much greater emphasis on restaurant dining is required, given the high proportion of seafood eaten in restaurants
Animal Ag Beyond all of the environmental and
human health concerns, much higher levels of consumer information are required to prevent market failure
