Abstract (sommario):
AbstractThis analysis used simulation to compare the cost of intergenerational transfer of farm estates under the pre-1981 tax rules and the Economic Recovery Tax Act of 1981 (ERTA) provisions. ERTA reduces transfer costs for almost all the estates considered. Large estates tend to benefit more than small estates if they qualify for use valuation or if they are large enough to be affected by the reduction in tax rates. ERTA does not create new forces for change in U.S. agriculture, but it tends to strengthen the tendency toward larger farm size and favor those who already own farm resources.

Abstract (sommario):
Soil structural degradation is a problem of some arable farms in New Zealand. This paper presents economic estimates of the significance of the loss of soil structure to farmers and the Manawatu region of New Zealand. Contingent valuation surveys of farmers and the wider community were used to estimate both use and non-use values. The results show the significance of compaction on both farm profits and land values, together with the lack of knowledge of the wider community concerning this problem. They reinforce the importance of careful farm practice, further scientific research, and a considered public policy response.

<p><span style="font-family: Times New Roman;">This study examined farmers’ willingness to pay for excreta pellet fertilizer in Ghana. Primary data was obtained from 461 farmers in 10 districts in the Western and Greater Accra regions of Ghana through randomized questionnaire administration. The contingent valuation method was used in eliciting the farmers’ willingness to pay decisions (WTP) and maximum amount they are willing to pay. The Tobit regression model results revealed that being a household head, unit cost of current fertilizer used, and farm size positively influenced the willingness to pay amount whereas previous use of organic fertilizer influenced the willingness to pay amount negatively.</span></p>

Abstract (sommario):
Purpose The purpose of this paper is to examine producer preferences for changing Farm Animal Welfare (FAW) levels in regards to sheep and goat husbandry in Bursa-Turkey. Design/methodology/approach The paper tests “panel estimators” in a stated preference data by using the payment card question format. Probit panels are employed to measure individual effects on FAW levels by considering producers’ willingness to accept. Three different FAW levels were identified for valuation as “base” level, “better” level, and the “best” level. The current study suggests a protocol with WTA(P) nomenclature to resolve complexity issues in FAW studies by investigating producers rather than consumers because the scenarios regarding FAW levels include quite technical and difficult topics which are vague to consumers. Findings If half of the total number of the sheep and goats in Turkey are assumed to be in bad animal welfare conditions, which are worse than base level, the non-use benefits of bringing them to at least the base level would be about US$130.3m. Figures would be 166.2m US$/year and 175m US$/year for “better” and “best” FAW conditions, respectively. Originality/value This paper provides a contribution to the existing literature by examining the producers’ responses to new FAW schemes. Also it helps policy makers to understand producers’ environmental behavior as well as their sensitivity to FAW schemes.

Abstract (sommario):
We introduce the industrial portfolio of a wind farm of a hypothetical company and its valuation consistent with the financial market. Next, we propose a static risk management policy originating from hedging against volumetric risk due to drops in wind intensity and we discuss the consequences. The hedging effectiveness firstly requires adequate modeling calibration and an extensive knowledge of these atypical financial (commodity) markets. In this hedging experiment, we find significant benefits for weather-sensitive companies, which can lead to new business opportunities. We provide a new financial econometrics approach to derive weather risk exposure in a typical wind farm. Our results show how accurate risk management can have a real benefit on corporate revenues. Specifically, we apply the spot market price simulation (SMaPS) model for the spot price of electricity. The parameters are calibrated using the prices of the French day-ahead market, and the historical series of the total hourly load is used as the final consumption. Next, we analyze wind speed and its relationship with electricity spot prices. As our main contribution, we demonstrate the effects of a hypothetical hedging strategy with collar options implemented against volumetric risk to satisfy demand at a specific time. Regarding the hedged portfolio, we observe that the “worst value” increases considerably while the earnings-at-risk (EaR) decreases. We consider only volumetric risk management, thus neglecting the market risk associated with electricity price volatility, allowing us to conclude that the hedging operation of our industrial portfolio provides substantial benefits in terms of the worst-case scenario.

Abstract (sommario):
Though water scarcity threats are increasing in severity across many regions of the world, allocation often remains inefficient — as in Jordan, the site of this study. One commonly discussed solution for increasing resource availability in water-scarce regions is the use of recycled wastewater for irrigation. Yet, despite significant potential benefits, an oft-cited concern with wastewater reuse is its potential impact on water quality. This paper examines the impact of this solution by exploiting a natural experiment arising from complementary infrastructure investments that introduced recycled wastewater to a new region of the Jordan Valley. We study farmer preferences for wastewater reuse, as well as farm adaptation and profitability. We find no evidence of negative impacts on farm revenues or costs over the short term, and observe signs of adaptation via the shifting of production toward less-salinity sensitive crops. Contingent valuation measures of the willingness to pay for reliable recycled water supply across newly treated and comparison areas indicate resistance to the expanded reuse of wastewater, however, which suggests that farmers may believe that this shift will entail more substantial long-term costs. Furthermore, the stated willingness to pay and short-term marginal productivity of water estimates appear unrelated. These results suggest the need for caution in interpreting short-term adaptation and preference responses to policies that substantially alter irrigation choices and behaviors, and point to the need for longer-term studies of wastewater reuse.

Abstract (sommario):
Purpose – The fisheries and aquaculture industry has observed substantial reduction in the demand for farmed Atlantic salmon after the food incidence of polychlorinated biphenyls in the product. To regain consumer confidence in the quality and safety of the product new policies, such as advanced traceability and identity preservation systems in the fisheries and aquaculture industry have been suggested. The purpose of this paper is to examine consumers’ preferences to pay a premium price for certified farmed Atlantic salmon that is passed through various quality and traceability systems in the province of Newfoundland and Labrador, Canada. Design/methodology/approach – The paper uses the contingent valuation (CV) method by estimating a probit regression model to assess consumers’ preferences for certified farmed Atlantic salmon. In particular, the paper measures consumers’ willingness to pay (WTP) a premium price to purchase the product. The CV method is the most widely used methodology in measuring individuals’ attitudes toward purchasing certified products. To estimate the parameters of the model, the authors carried out a consumer survey in spring 2010 and successfully completed 120 questionnaires in the province. Findings – The paper provides empirical insights about how households are interested in consuming certified farm-raised Atlantic salmon by paying an additional premium price to purchase the product. The results of the study show that although consumers believe that traceability methods, on average, will increase the price of certified farmed Atlantic salmon their preferences toward the consumption of the product will not be changed. Research limitations/implications – Since the paper uses the CV method to evaluate individuals’ preferences for certified farm-raised Atlantic salmon, the authors also suggest another study that uses a non-hypothetical choice experimental approach to elicit households’ WTP a premium price for the product. Originality/value – This paper shows how consumers’ decisions to purchase certified farm-raised Atlantic salmon can be affected by a series of demographic, socio-economicand other variables that reflect consumers’ awareness of issues surroundings farmed Atlantic salmon and quality assurance.

Abstract (sommario):
Background While the importance of conserving ecosystems for sustainable development is widely recognized, it is increasingly evident that despite delivering global benefits, conservation often comes at local cost. Protected areas funded by multilateral lenders have explicit commitments to ensure that those negatively affected are adequately compensated. We make the first comparison of the magnitude and distribution of the local costs of a protected area with the magnitude and distribution of the compensation provided under the World Bank social safeguard policies (Performance Standard 5). Methods In the Ankeniheny-Zahamena Corridor (a new protected area and REDD+ pilot project in eastern Madagascar), we used choice experiments to estimate local opportunity costs (n = 453) which we annualized using a range of conservative assumptions concerning discount rates. Detailed surveys covering farm inputs and outputs as well as off-farm income (n = 102) allowed us to explore these opportunity costs as a proportion of local incomes. Intensive review of publically available documents provided estimates of the number of households that received safeguard compensation and the amount spent per household. We carried out a contingent valuation exercise with beneficiaries of this compensation two years after the micro-development projects were implemented (n = 62) to estimate their value as perceived by beneficiaries. Results Conservation restrictions result in very significant costs to forest communities. The median net present value of the opportunity cost across households in all sites was US$2,375. When annualized, these costs represent 27–84% of total annual income for median-income households; significantly higher proportionally for poorer households. Although some households have received compensation, we conservatively estimate that more than 50% of eligible households (3,020 households) have not. Given the magnitude of compensation (based both on amount spent and valuation by recipients two years after the compensation was distributed) relative to costs, we argue that no one was fully compensated. Achieving full compensation will require an order of magnitude more than was spent but we suggest that this should be affordable given the global value of forest conservation. Discussion By analyzing in unprecedented depth both the local costs of conservation, and the compensation distributed under donor policies, we demonstrate that despite well-intentioned policies, some of the poorest people on the planet are still bearing the cost of forest conservation. Unless significant extra funding is provided by the global beneficiaries of conservation, donors’ social safeguarding requirements will not be met, and forest conservation in developing countries will jeopardize, rather than contribute to, sustainable development goals.

Abstract (sommario):
AbstractThe traditional concerns about farm animal welfare have centred around the impact of intensive environments and management practices on the animal. This emphasis on the physical environment is changing, however, with greater consideration being given to animal factors and in particular to the selective breeding of farm animals. In this paper we use examples from our own research on dairy cattle and sheep breeding that have made positive and practical contributions towards reducing welfare problems by creating more balanced breeding programmes. In both examples, inclusion of health and fitness traits into breeding indexes can be shown to be more profitable than selecting on production traits alone. In addition, we propose that in principle animal breeding combined with economics research can make a more general contribution towards resolving animal welfare issues, by providing a framework for the quantitative evaluation of the costs and benefits of an animal production system. The advantage of the approaches currently used in multi-trait selection is that they transform all traits (production-based or welfare-based) to a common currency allowing direct comparisons of costs and benefits. Currently the weights applied to traits reflect their economic value to the producer. This approach is likely to underestimate non-economic welfare aspects such as the pain or discomfort associated with lameness, and new approaches are needed to more fully account for these non-economic welfare costs. We therefore propose that consideration is given to the use of approaches such as contingent valuation, which has been widely used in economics to derive values for non-economic activities. The question of who would pay for the addition of these welfare costs to a breeding index remains open, but it would seem most reasonable to treat these as a public good and pay for them as such through appropriate mechanisms.

PurposeThis paper aims to describe the nature of an agricultural lending position and reports an industry perspective of skills required for a new graduate entering the profession.Design/methodology/approachLoan officers and those directly supervising loan officers were surveyed regarding job characteristics and perceptions of the skills needed for career success.FindingsLenders perceive on-the-job training to be slightly more valuable than post-secondary training for preparing students for a career in agricultural lending. Financial skills were rated to be roughly as important as non-financial skills for early career success. Financial topics identified as important include financial statements, breakeven analysis and accrual-basis earnings. Communication and risk analysis were rated as the most important non-financial topics needed for early career success. Regarding their jobs, lenders indicated that they devote much of their time to managing loans and developing or maintaining relationships with customers. Benefits were identified as the most important feature for job satisfaction, particularly among agricultural lenders, that also work essentially full time on a farm or ranch. Work environment, work flexibility, location and salary were also considered to be important job characteristics.Originality/valueThis paper updates the literature regarding industry's preferred skills and refines the surveyed audience to only those currently performing or directly supervising agricultural lending. It adds a unique perspective on the work time allocated to various agricultural lending activities and lenders' valuation of job characteristics. These insights may guide curricular and course design, career planning and employee recruitment and marketing efforts.

Abstract (sommario):
In the light of the Treaty establishing the European Economic Community (Treaty of Rome) of 25 March 1957, the primary aim of the Common Agricultural Policy is to provide European Economic Community citizens with adequate amounts of food at reasonable prices and to guarantee farmers a decent standard of living. That is more, the EU fund transfers were to eliminate differences between regions and promote development of individual regions. These aims proved to be particularly important following the EU enlargement in 2004. The indispensible effect of the integration process has been connected with changes in the directions of agricultural production and efficiency of utilisation of individual inputs. Nevertheless, it is difficult to evaluate the effects of the implemented policy based on univariate comparisons. In view of the above, the aim of this paper is to assess the effects of the agricultural policy and the cohesion policy implemented in the EU, focusing on the valuation of the impact of the greatest EU enlargement on this relationship. This goal was achieved thanks to constructing multivariate rankings applying the DEA super-efficiency model for average farms specialising in plant, animal and mixed production in individual EU member countries for two period. The application of the DEA efficiency model makes it possible in the computation process to take into consideration the fact that in the course of agricultural production three groups of products are manufactured involving four basic types of inputs. The starting point for the analyses was provided by data published within the FADN agenda for average farms operating in the countries being the EU members. The results showed that after the largest enlargement of the EU, in the case of plant and livestock production, a simultaneous increase in agricultural production and improvement in efficiency in the individual EU members was achieved, with a gradual reduction of disproportions in the efficiency of agricultural production between regions. The only area where such a relationship could not be observed was related to the production of mixed-type farms. The novelty of the proposed in this article approach is that it allows for simultaneous analysing of changes in EU agriculture while taking into account several perspectives: changes in the assumptions of the common agricultural policy, the consequences of EU enlargement, and results of the implementation of the cohesion policy.

The purpose of the article is to light up scientific approaches and technological solutions that provided IV Smirnov's experimentally establish property of mammalian sperm to preserve biological value and genetic information after freezing at temperatures below -200C, to obtain normal offspring from frozen sperm. Research methods: general scientific, retrospective, source studies. The discovery of I. V. Smirnov became the basis of the scientific and technological revolution in the field of breeding and improvement of farm animals, contributed to the development of a new direction of research in the theory and practice of animal breeding, genetic methods of bulls valuation by genotype. Long-term storage of deep-frozen gametes in liquid nitrogen ensured efficient use of valuable animals, regardless of the country where they are kept, and time of use, which significantly increased the efficiency of selection. Thanks to the discovery of I. V. Smirnov, large-scale genotypic selection was introduced in many countries of the world, which was initiated by O. V. Garkavy (1928) and O. O. Serebrovsky (1934). Due to extensive use of the world's best gene pool of specialized dairy breeds, in Ukraine have highly productive domestic breeds of dairy cattle been created: Ukrainian red-and-white, black-and-white, red and brown dairy. The genetic potential of these breeds in breeding plants is 9–10 thousand kg of milk from cows per year, and in the public sector – 6–7 thousand kg, which is 3–4 times higher than the original breeds on which they were created. The use of deep-frozen sperm and embryos has become global. Modern methods of biotechnology, freezing of gametes of other species of animals and embryo transplantation, in vitro fertilization, transgenic engineering, organ transplantation in medicine, etc. are based on IV Smyrnov's discovery. The world's most difficult problem is the preservation of the gene pool of farm animals and the biological diversity of wild fauna, also solved by this discovery. At present, in the sperm and embryo repositories are genetic information of prominent offspring and queens and embryos of commercial and endangered populations stored. The great scientist was an excellent teacher. He gave brilliant lectures to students, livestock specialists, formed his own school, trained many candidates and doctors of sciences, 3,500 highly qualified specialists and more than two thousand laboratory technicians. With his theoretical developments and their practical implementation IV Smirnov initiated a new direction and methods of scientific research in the field of biology, organizational forms of selection and reproduction of animals, which acquired planetary significance and became an indispensable heritage of mankind. His scientific heritage is one of the greatest discoveries of the human mind and is the pride of domestic zootechnics.

Abstract (sommario):
Agricultural land is a very important ecosystem that provides a range of services like food, maintenance of soil structure, and hydrological services with high ecological value to human wellbeing Ecosystem Services (ESs). Understanding the contribution of different agricultural practices to supply ESs would help inform choices about the most beneficial land use management. Nature-based Solutions (NbS) are defined by IUCN (International Union for Conservation of Nature) as actions to protect, sustainably manage and restore natural or modified ecosystems, which address societal challenges (e.g., climate change, food and water security, or natural disasters) effectively and adaptively, while simultaneously providing human wellbeing and biodiversity benefits. Some actions farmers can implement in the new Rural Development Programs (RDP 2021–2022 and 2023–2027) can be considered as NbS and could affect the quantity, quality, and time of some ESs related to water regulation and supply, N adsorption and erosion protection. This study aims to evaluate these ESs in different scenarios in the upper Foglia river basin (Italy) and at a local scale (farming), and to highlight the issue to compensate farmers for the production of public goods which benefit the whole society (ESs) by the implementation of RDP’s actions. These scenarios highlight how actions have positive effects on ecosystem services and their economic value related to land use management, on maintaining agricultural practices by integrating Water Frame Directive (2000/60/EC), Directive 2007/60/EC on the management of flood risks and highlighting the potential role of farmers in a high diversity landscape. This study highlights a new way to evaluate the processes of natural capital in the production of public goods, which benefits the whole society (ESs), by emphasizing the economic and environmental role of farmers in producing them and putting on the table data to trigger a PES (Payment for Ecosystem Services) mechanism. To facilitate decision making, robust decision support tools are needed, underpinned by comprehensive cost-benefit analyses and spatially modeling in which agriculture can be a strategic sector to optimize food production and environmental protection in harmony with the Farm to Fork (F2F) strategy.

Abstract (sommario):
The stock unit (SU) system is used extensively in New Zealand agriculture. These applications include inter- and intra-farm comparisons, rural lending and valuation, and farm system design and analysis. The livestock classes and performance levels to which SU conversion factors are applied has increased significantly since Professor Coop defined the ewe equivalent (EE) system, and now includes deer, goats and other non-conventional livestock species. This has led to a proliferation of SU values and their incorrect application and interpretation, especially in between-farm comparative analysis. Benchmarking provides a more economically rational way of improving the profitability of livestock farms than the use of standards based on SUs. Obtaining agreement on the specifications of animal-pasture-financial models to allow users to derive substitution rates between stock classes according to their farm's resources and management practice is preferred to publishing national standards for SUs.

Abstract (sommario):
Abstract Risk and risk preferences belong to the key determinants of investment-based technology adoption in agriculture. We develop and apply a novel approach in which an inverse second order stochastic dominance approach is integrated into a stochastic dynamic farm-level model to quantify the effect of both risk and risk aversion on the timing and scale of agricultural technology adoption. Our illustrative example on short rotation coppice adoption shows that risk aversion leads to technology adoption that takes place earlier, but to a smaller extent. In contrast, higher levels of risk exposure lead to postponed but overall larger adoption. These effects would be obscured if technology adoption is not analyzed in a farm-scale context or considered as a now-or-never decision, the still dominant approach in the literature.

Abstract (sommario):
PurposeThis study aims to evaluate a hydroponic farm (through nutrient film technique) while considering uncertainty, sustainability and the system's utility in the dominant desert geography. The idea of the hydroponic farm is to allow individuals/businesses to grow plants. Given the geographical condition, the hydroponic system may be useful in the Gulf context and may lead to food security and sustainability. Additionally, the UAE government has initiated several support schemes that can be availed for investing in such businesses that can contribute to the nation's food security.Design/methodology/approachThe hydroponic farm is evaluated using the net present value and real options approach. The authors studied five scenarios: 1. business as usual, 2. 50% subsidy on initial investment through Khalifa funding, 3. 4% premium, 4. Subsidy plus premium and 5. solar panel installation with bore well.FindingsAs per the assumptions and data usage, all the scenarios shows a positive net present value (NPV); Nevertheless, scenarios 4 and 5 report the significant highest net present and delay value.Research limitations/implicationsThis study has environmental, economic and social implications. Lower imports indirectly lead to lower carbon footprints. The local production of food ensures higher employability in the sector and increase in local consumption. Additionally, fresh food consumption is directly associated to good health.Practical implicationsSupportive policies such as subsidies through Khalifa funding may accelerate the expansion of such projects through domestic and foreign investments. One of the important takeaway from the study is to invest in the training of the workforce.Social implicationsGiven the geographical condition, the UAE usually depends on food imports. If the hydroponic farms become popular, the residents will have access to fresh vegetables and fruits. Higher engagement in agriculture activities also ensures a significant increase in agriculture-related businesses and higher employability.Originality/valueThe study adds novelty to the literature because the effect of Khalifa funding and investment analysis on solar (wells) has not been evaluated in any hydroponic studies. We presented the results with tornado graphs using NPV risk and real options approach in the Gulf context. The study represents functional scenarios that were previously not found in the literature.

Abstract (sommario):
Abstract This paper analyses farmland price formation under investors’ increased demand in the Czech Republic from 2008 to 2014. We adopt a stochastic metafrontier approach to hedonic price modelling and investigate the relative differences in farm and investor pricing. Our results provide evidence of buyer group-specific land valuations, asymmetric price dispersions and their temporal changes. These changes reflect the developments of market microstructures and market-supporting institutions induced by buyer competition. While initially significantly lower due to high market and bargaining power, prices paid by corporate/cooperative farms converged with high-level investor prices over time. Individual and family farms were largely unable to compete at the new price levels.

Abstract (sommario):
AbstractThis paper examines households’ preferences, willingness to pay, and determinants of adopting improved cook stoves in rural Ethiopia. The study uses primary household data selected randomly from three districts in Ethiopia’s Oromia region. The data was collected using a mix of contingent and choice experiment methods of valuation. The former used a double-bounded value elicitation method, while the latter used a fractional factorial design to efficiently generate an attribute and level combination for the improved cook stoves. The study also used various discrete choice models for data analysis and also used models which account for scale and preference heterogeneity. The findings show that the sample households were aware of the effects of using traditional cook stoves and the benefits of using improved cook stoves. However, they were constrained by the availability of the new technology and discouraged by the low-quality of the products that they had used so far. The estimated mean willingness to pay ranged from about 150 Birr to 350 Birr which is lower than the market price of the improved cook stoves. Emission reduction, reducing fire risks, and the durability of the cook stove positively affected its adoption, while price discouraged its use. Higher levels of education, higher incomes, non-farm employment, and having more livestock increased the probability of adopting the new gas stoves. The study recommends that policymakers and product designers should use the mean willingness to pay and marginal rate of substitution for the different attributes as a benchmark for product design and pricing that fit households’ preferences and ability to pay. The lower mean willingness to pay means that a public subsidizing policy is needed for effectively disseminating improved cook stoves in rural Ethiopia.

Abstract (sommario):
Kangatarianism is the rather inelegant word coined in the first decade of the twenty-first century to describe an omnivorous diet in which the only meat consumed is that of the kangaroo. First published in the media in 2010 (Barone; Zukerman), the term circulated in Australian environmental and academic circles including the Global Animal conference at the University of Wollongong in July 2011 where I first heard it from members of the Think Tank for Kangaroos (THINKK) group. By June 2017, it had gained enough attention to be named the Oxford English Dictionary’s Australian word of the month (following on from May’s “smashed avo,” another Australian food innovation), but it took the Nine Network reality television series Love Island Australia to raise kangatarian to trending status on social media (Oxford UP). During the first episode, aired in late May 2018, Justin, a concreter and fashion model from Melbourne, declared himself to have previously been a kangatarian as he chatted with fellow contestant, Millie. Vet nurse and animal lover Millie appeared to be shocked by his revelation but was tentatively accepting when Justin explained what kangatarian meant, and justified his choice on the grounds that kangaroo are not farmed. In the social media response, it was clear that eating only the meat of kangaroos as an ethical choice was an entirely new concept to many viewers, with one tweet stating “Kangatarian isn’t a thing”, while others variously labelled the diet brutal, intriguing, or quintessentially Australian (see #kangatarian on Twitter).There is a well developed literature around the arguments for and against eating kangaroo, and why settler Australians tend to be so reluctant to do so (see for example, Probyn; Cawthorn and Hoffman). Here, I will concentrate on the role that ethics play in this food choice by examining how the adoption of kangatarianism can be understood as a bargain struck to help to manage grief in the Anthropocene, and the limitations of that bargain. As Lesley Head has argued, we are living in a time of loss and of grieving, when much that has been taken for granted is becoming unstable, and “we must imagine that drastic changes to everyday life are in the offing” (313). Applying the classic (and contested) model of five stages of grief, first proposed by Elisabeth Kübler-Ross in her book On Death and Dying in 1969, much of the population of the western world seems to be now experiencing denial, her first stage of loss, while those in the most vulnerable environments have moved on to anger with developed countries for destructive actions in the past and inaction in the present. The next stages (or states) of grieving—bargaining, depression, and acceptance—are likely to be manifested, although not in any predictable sequence, as the grief over current and future losses continues (Haslam).The great expansion of food restrictive diets in the Anthropocene can be interpreted as part of this bargaining state of grieving as individuals attempt to respond to the imperative to reduce their environmental impact but also to limit the degree of change to their own diet required to do so. Meat has long been identified as a key component of an individual’s environmental footprint. From Frances Moore Lappé’s 1971 Diet for a Small Planet through the United Nations’ Food and Agriculture Organisation’s 2006 report Livestock’s Long Shadow to the 2019 report of the EAT–Lancet Commission on Healthy Diets from Sustainable Food Systems, the advice has been consistent: meat consumption should be minimised in, if not eradicated from, the human diet. The EAT–Lancet Commission Report quantified this to less than 28 grams (just under one ounce) of beef, lamb or pork per day (12, 25). For many this would be keenly felt, in terms of how meals are constructed, the sensory experiences associated with eating meat and perceptions of well-being but meat is offered up as a sacrifice to bring about the return of the beloved healthy planet.Rather than accept the advice to cut out meat entirely, those seeking to bargain with the Anthropocene also find other options. This has given rise to a suite of foodways based around restricting meat intake in volume or type. Reducing the amount of commercially produced beef, lamb and pork eaten is one approach, while substituting a meat the production of which has a smaller environmental footprint, most commonly chicken or fish, is another. For those willing to make deeper changes, the meat of free living animals, especially those which are killed accidentally on the roads or for deliberately for environmental management purposes, is another option. Further along this spectrum are the novel protein sources suggested in the Lancet report, including insects, blue-green algae and laboratory-cultured meats.Kangatarianism is another form of this bargain, and is backed by at least half a century of advocacy. The Australian Conservation Foundation made calls to reduce the numbers of other livestock and begin a sustainable harvest of kangaroo for food in 1970 when the sale of kangaroo meat for human consumption was still illegal across the country (Conservation of Kangaroos). The idea was repeated by biologist Gordon Grigg in the late 1980s (Jackson and Vernes 173), and again in the Garnaut Climate Change Review in 2008 (547–48). Kangaroo meat is high in protein and iron, low in fat, and high in healthy polyunsaturated fatty acids and conjugated linoleic acid, and, as these authors showed, has a smaller environmental footprint than beef, lamb, or pork. Kangaroo require less water than cattle, sheep or pigs, and no land is cleared to grow feed for them or give them space to graze. Their paws cause less erosion and compaction of soil than do the hooves of common livestock. They eat less fodder than ruminants and their digestive processes result in lower emissions of the powerful greenhouse gas methane and less solid waste.As Justin of Love Island was aware, kangaroo are not farmed in the sense of being deliberately bred, fed, confined, or treated with hormones, drugs or chemicals, which also adds to their lighter impact on the environment. However, some pastoralists argue that because they cannot prevent kangaroos from accessing the food, water, shelter, and protection from predators they provide for their livestock, they do effectively farm them, although they receive no income from sales of kangaroo meat. This type of light touch farming of kangaroos has a very long history in Australia going back to the continent’s first peopling some 60,000 years ago. Kangaroos were so important to Aboriginal people that a wide range of environments were manipulated to produce their favoured habitats of open grasslands edged by sheltering trees. As Bill Gammage demonstrated, fire was used as a tool to preserve and extend grassy areas, to encourage regrowth which would attract kangaroos and to drive the animals from one patch to another or towards hunters waiting with spears (passim, for example, 58, 72, 76, 93). Gammage and Bruce Pascoe agree that this was a form of animal husbandry in which the kangaroos were drawn to the areas prepared for them for the young grass or, more forcefully, physically directed using nets, brush fences or stone walls. Burnt ground served to contain the animals in place of fencing, and regular harvesting kept numbers from rising to levels which would place pressure on other species (Gammage 79, 281–86; Pascoe 42–43). Contemporary advocates of eating kangaroo have promoted the idea that they should be deliberately co-produced with other livestock instead of being killed to preserve feed and water for sheep and cattle (Ellicott; Wilson 39). Substituting kangaroo for the meat of more environmentally damaging animals would facilitate a reduction in the numbers of cattle and sheep, lessening the harm they do.Most proponents have assumed that their audience is current meat eaters who would substitute kangaroo for the meat of other more environmentally costly animals, but kangatarianism can also emerge from vegetarianism. Wendy Zukerman, who wrote about kangaroo hunting for New Scientist in 2010, was motivated to conduct the research because she was considering becoming an early adopter of kangatarianism as the least environmentally taxing way to counter the longterm anaemia she had developed as a vegetarian. In 2018, George Wilson, honorary professor in the Australian National University’s Fenner School of Environment and Society called for vegetarians to become kangatarians as a means of boosting overall consumption of kangaroo for environmental and economic benefits to rural Australia (39).Given these persuasive environmental arguments, it might be expected that many people would have perceived eating kangaroo instead of other meat as a favourable bargain and taken up the call to become kangatarian. Certainly, there has been widespread interest in trying kangaroo meat. In 1997, only five years after the sale of kangaroo meat for human consumption had been legalised in most states (South Australia did so in 1980), 51% of 500 people surveyed in five capital cities said they had tried kangaroo. However, it had not become a meat of choice with very few found to eat it more than three times a year (Des Purtell and Associates iv). Just over a decade later, a study by Ampt and Owen found an increase to 58% of 1599 Australians surveyed across the country who had tried kangaroo but just 4.7% eating it at least monthly (14). Bryce Appleby, in his study of kangaroo consumption in the home based on interviews with 28 residents of Wollongong in 2010, specifically noted the absence of kangatarians—then a very new concept. A study of 261 Sydney university students in 2014 found that half had tried kangaroo meat and 10% continued to eat it with any regularity. Only two respondents identified themselves as kangatarian (Grant 14–15). Kangaroo meat advocate Michael Archer declared in 2017 that “there’s an awful lot of very, very smart vegetarians [who] have opted for semi vegetarianism and they’re calling themselves ‘kangatarians’, as they’re quite happy to eat kangaroo meat”, but unless there had been a significant change in a few years, the surveys did not bear out his assertion (154).The ethical calculations around eating kangaroo are complicated by factors beyond the strictly environmental. One Tweeter advised Justin: “‘I’m a kangatarian’ isn’t a pickup line, mate”, and certainly the reception of his declaration could have been very cool, especially as it was delivered to a self declared animal warrior (N’Tash Aha). All of the studies of beliefs and practices around the eating of kangaroo have noted a significant minority of Australians who would not consider eating kangaroo based on issues of animal welfare and animal rights. The 1997 study found that 11% were opposed to the idea of eating kangaroo, while in Grant’s 2014 study, 15% were ethically opposed to eating kangaroo meat (Des Purtell and Associates iv; Grant 14–15). Animal ethics complicate the bargains calculated principally on environmental grounds.These ethical concerns work across several registers. One is around the flesh and blood kangaroo as a charismatic native animal unique to Australia and which Australians have an obligation to respect and nurture. Sheep, cattle and pigs have been subject to longterm propaganda campaigns which entrench the idea that they are unattractive and unintelligent, and veil their transition to meat behind euphemistic language and abattoir walls, making it easier to eat them. Kangaroos are still seen as resourceful and graceful animals, and no linguistic tricks shield consumers from the knowledge that it is a roo on their plate. A proposal in 2009 to market a “coat of arms” emu and kangaroo-flavoured potato chip brought complaints to the Advertising Standards Bureau that this was disrespectful to these native animals, although the flavours were to be simulated and the product vegetarian (Black). Coexisting with this high regard to kangaroos is its antithesis. That is, a valuation of them informed by their designation as a pest in the pastoral industry, and the use of the carcasses of those killed to feed dogs and other companion animals. Appleby identified a visceral, disgust response to the idea of eating kangaroo in many of his informants, including both vegetarians who would not consider eating kangaroo because of their commitment to a plant-based diet, and at least one omnivore who would prefer to give up all meat rather than eat kangaroo. While diametrically opposed, the end point of both positions is that kangaroo meat should not be eaten.A second animal ethics stance relates to the imagined kangaroo, a cultural construct which for most urban Australians is much more present in their lives and likely to shape their actions than the living animals. It is behind the rejection of eating an animal which holds such an iconic place in Australian culture: to the dexter on the 1912 national coat of arms; hopping through the Hundred Acre Wood as Kanga and Roo in A.A. Milne’s Winnie-the-Pooh children’s books from the 1920s and the Disney movies later made from them; as a boy’s best friend as Skippy the Bush Kangaroo in a fondly remembered 1970s television series; and high in the sky on QANTAS planes. The anthropomorphising of kangaroos permitted the spectacle of the boxing kangaroo from the late nineteenth century. By framing natural kangaroo behaviours as boxing, these exhibitions encouraged an ambiguous understanding of kangaroos as human-like, moving them further from the category of food (Golder and Kirkby). Australian government bodies used this idea of the kangaroo to support food exports to Britain, with kangaroos as cooks or diners rather than ingredients. The Kangaroo Kookery Book of 1932 (see fig. 1 below) portrayed kangaroos as a nuclear family in a suburban kitchen and another official campaign supporting sales of Australian produce in Britain in the 1950s featured a Disney-inspired kangaroo eating apples and chops washed down with wine (“Kangaroo to Be ‘Food Salesman’”). This imagining of kangaroos as human-like has persisted, leading to the opinion expressed in a 2008 focus group, that consuming kangaroo amounted to “‘eating an icon’ … Although they are pests they are still human nature … these are native animals, people and I believe that is a form of cannibalism!” (Ampt and Owen 26). Figure 1: Rather than promoting the eating of kangaroos, the portrayal of kangaroos as a modern suburban family in the Kangaroo Kookery Book (1932) made it unthinkable. (Source: Kangaroo Kookery Book, Director of Australian Trade Publicity, Australia House, London, 1932.)The third layer of ethical objection on the ground of animal welfare is more specific, being directed to the method of killing the kangaroos which become food. Kangaroos are perhaps the only native animals for which state governments set quotas for commercial harvest, on the grounds that they compete with livestock for pasturage and water. In most jurisdictions, commercially harvested kangaroo carcasses can be processed for human consumption, and they are the ones which ultimately appear in supermarket display cases.Kangaroos are killed by professional shooters at night using swivelling spotlights mounted on their vehicles to locate and daze the animals. While clean head shots are the ideal and regulations state that animals should be killed when at rest and without causing “undue agonal struggle”, this is not always achieved and some animals do suffer prolonged deaths (NSW Code of Practice for Kangaroo Meat for Human Consumption). By regulation, the young of any female kangaroo must be killed along with her. While averting a slow death by neglect, this is considered cruel and wasteful. The hunt has drawn international criticism, including from Greenpeace which organised campaigns against the sale of kangaroo meat in Europe in the 1980s, and Viva! which was successful in securing the withdrawal of kangaroo from sale in British supermarkets (“Kangaroo Meat Sales Criticised”). These arguments circulate and influence opinion within Australia.A final animal ethics issue is that what is actually behind the push for greater use of kangaroo meat is not concern for the environment or animal welfare but the quest to turn a profit from these animals. The Kangaroo Industries Association of Australia, formed in 1970 to represent those who dealt in the marsupials’ meat, fur and skins, has been a vocal advocate of eating kangaroo and a sponsor of market research into how it can be made more appealing to the market. The Association argued in 1971 that commercial harvest was part of the intelligent conservation of the kangaroo. They sought minimum size regulations to prevent overharvesting and protect their livelihoods (“Assn. Backs Kangaroo Conservation”). The Association’s current website makes the claim that wild harvested “Australian kangaroo meat is among the healthiest, tastiest and most sustainable red meats in the world” (Kangaroo Industries Association of Australia). That this is intended to initiate a new and less controlled branch of the meat industry for the benefit of hunters and processors, rather than foster a shift from sheep or cattle to kangaroos which might serve farmers and the environment, is the opinion of Dr. Louise Boronyak, of the Centre for Compassionate Conservation at the University of Technology Sydney (Boyle 19).Concerns such as these have meant that kangaroo is most consumed where it is least familiar, with most of the meat for human consumption recovered from culled animals being exported to Europe and Asia. Russia has been the largest export market. There, kangaroo meat is made less strange by blending it with other meats and traditional spices to make processed meats, avoiding objections to its appearance and uncertainty around preparation. With only a low profile as a novelty animal in Russia, there are fewer sentimental concerns about consuming kangaroo, although the additional food miles undermine its environmental credentials. The variable acceptability of kangaroo in more distant markets speaks to the role of culture in determining how patterns of eating are formed and can be shifted, or, as Elspeth Probyn phrased it “how natural entities are transformed into commodities within a context of globalisation and local communities”, underlining the impossibility of any straightforward ethics of eating kangaroo (33, 35).Kangatarianism is a neologism which makes the eating of kangaroo meat something it has not been in the past, a voluntary restriction based on environmental ethics. These environmental benefits are well founded and eating kangaroo can be understood as an Anthropocenic bargain struck to allow the continuation of the consumption of red meat while reducing one’s environmental footprint. Although superficially attractive, the numbers entering into this bargain remain small because environmental ethics cannot be disentangled from animal ethics. The anthropomorphising of the kangaroo and its use as a national symbol coexist with its categorisation as a pest and use of its meat as food for companion animals. Both understandings of kangaroos made their meat uneatable for many Australians. Paired with concerns over how kangaroos are killed and the commercialisation of a native species, kangaroo meat has a very mixed reception despite decades of advocacy for eating its meat in favour of that of more harmed and more harmful introduced species. Given these constraints, kangatarianism is unlikely to become widespread and indeed it should be viewed as at best a temporary exigency. As the climate warms and rainfall becomes more erratic, even animals which have evolved to suit Australian conditions will come under increasing pressure, and humans will need to reach Kübler-Ross’ final state of grief: acceptance. In this case, this would mean acceptance that our needs cannot be placed ahead of those of other animals.ReferencesAmpt, Peter, and Kate Owen. Consumer Attitudes to Kangaroo Meat Products.

Abstract (sommario):
A same-but-different dichotomy has recently been encapsulated within the US Food and Drug Administration’s ill-defined concept of “substantial equivalence” (USFDA, FDA). By invoking this concept the genetically modified organism (GMO) industry has escaped the rigors of safety testing that might otherwise apply. The curious concept of “substantial equivalence” grants a presumption of safety to GMO food. This presumption has yet to be earned, and has been used to constrain labelling of both GMO and non-GMO food. It is an idea that well serves corporatism. It enables the claim of difference to secure patent protection, while upholding the contrary claim of sameness to avoid labelling and safety scrutiny. It offers the best of both worlds for corporate food entrepreneurs, and delivers the worst of both worlds to consumers. The term “substantial equivalence” has established its currency within the GMO discourse. As the opportunities for patenting food technologies expand, the GMO recruitment of this concept will likely be a dress rehearsal for the developing debates on the labelling and testing of other techno-foods – including nano-foods and clone-foods. “Substantial Equivalence” “Are the Seven Commandments the same as they used to be, Benjamin?” asks Clover in George Orwell’s “Animal Farm”. By way of response, Benjamin “read out to her what was written on the wall. There was nothing there now except a single Commandment. It ran: ALL ANIMALS ARE EQUAL BUT SOME ANIMALS ARE MORE EQUAL THAN OTHERS”. After this reductionist revelation, further novel and curious events at Manor Farm, “did not seem strange” (Orwell, ch. X). Equality is a concept at the very core of mathematics, but beyond the domain of logic, equality becomes a hotly contested notion – and the domain of food is no exception. A novel food has a regulatory advantage if it can claim to be the same as an established food – a food that has proven its worth over centuries, perhaps even millennia – and thus does not trigger new, perhaps costly and onerous, testing, compliance, and even new and burdensome regulations. On the other hand, such a novel food has an intellectual property (IP) advantage only in terms of its difference. And thus there is an entrenched dissonance for newly technologised foods, between claiming sameness, and claiming difference. The same/different dilemma is erased, so some would have it, by appeal to the curious new dualist doctrine of “substantial equivalence” whereby sameness and difference are claimed simultaneously, thereby creating a win/win for corporatism, and a loss/loss for consumerism. This ground has been pioneered, and to some extent conquered, by the GMO industry. The conquest has ramifications for other cryptic food technologies, that is technologies that are invisible to the consumer and that are not evident to the consumer other than via labelling. Cryptic technologies pertaining to food include GMOs, pesticides, hormone treatments, irradiation and, most recently, manufactured nano-particles introduced into the food production and delivery stream. Genetic modification of plants was reported as early as 1984 by Horsch et al. The case of Diamond v. Chakrabarty resulted in a US Supreme Court decision that upheld the prior decision of the US Court of Customs and Patent Appeal that “the fact that micro-organisms are alive is without legal significance for purposes of the patent law”, and ruled that the “respondent’s micro-organism plainly qualifies as patentable subject matter”. This was a majority decision of nine judges, with four judges dissenting (Burger). It was this Chakrabarty judgement that has seriously opened the Pandora’s box of GMOs because patenting rights makes GMOs an attractive corporate proposition by offering potentially unique monopoly rights over food. The rear guard action against GMOs has most often focussed on health repercussions (Smith, Genetic), food security issues, and also the potential for corporate malfeasance to hide behind a cloak of secrecy citing commercial confidentiality (Smith, Seeds). Others have tilted at the foundational plank on which the economics of the GMO industry sits: “I suggest that the main concern is that we do not want a single molecule of anything we eat to contribute to, or be patented and owned by, a reckless, ruthless chemical organisation” (Grist 22). The GMO industry exhibits bipolar behaviour, invoking the concept of “substantial difference” to claim patent rights by way of “novelty”, and then claiming “substantial equivalence” when dealing with other regulatory authorities including food, drug and pesticide agencies; a case of “having their cake and eating it too” (Engdahl 8). This is a clever slight-of-rhetoric, laying claim to the best of both worlds for corporations, and the worst of both worlds for consumers. Corporations achieve patent protection and no concomitant specific regulatory oversight; while consumers pay the cost of patent monopolization, and are not necessarily apprised, by way of labelling or otherwise, that they are purchasing and eating GMOs, and thereby financing the GMO industry. The lemma of “substantial equivalence” does not bear close scrutiny. It is a fuzzy concept that lacks a tight testable definition. It is exactly this fuzziness that allows lots of wriggle room to keep GMOs out of rigorous testing regimes. Millstone et al. argue that “substantial equivalence is a pseudo-scientific concept because it is a commercial and political judgement masquerading as if it is scientific. It is moreover, inherently anti-scientific because it was created primarily to provide an excuse for not requiring biochemical or toxicological tests. It therefore serves to discourage and inhibit informative scientific research” (526). “Substantial equivalence” grants GMOs the benefit of the doubt regarding safety, and thereby leaves unexamined the ramifications for human consumer health, for farm labourer and food-processor health, for the welfare of farm animals fed a diet of GMO grain, and for the well-being of the ecosystem, both in general and in its particularities. “Substantial equivalence” was introduced into the food discourse by an Organisation for Economic Co-operation and Development (OECD) report: “safety evaluation of foods derived by modern biotechnology: concepts and principles”. It is from this document that the ongoing mantra of assumed safety of GMOs derives: “modern biotechnology … does not inherently lead to foods that are less safe … . Therefore evaluation of foods and food components obtained from organisms developed by the application of the newer techniques does not necessitate a fundamental change in established principles, nor does it require a different standard of safety” (OECD, “Safety” 10). This was at the time, and remains, an act of faith, a pro-corporatist and a post-cautionary approach. The OECD motto reveals where their priorities lean: “for a better world economy” (OECD, “Better”). The term “substantial equivalence” was preceded by the 1992 USFDA concept of “substantial similarity” (Levidow, Murphy and Carr) and was adopted from a prior usage by the US Food and Drug Agency (USFDA) where it was used pertaining to medical devices (Miller). Even GMO proponents accept that “Substantial equivalence is not intended to be a scientific formulation; it is a conceptual tool for food producers and government regulators” (Miller 1043). And there’s the rub – there is no scientific definition of “substantial equivalence”, no scientific test of proof of concept, and nor is there likely to be, since this is a ‘spinmeister’ term. And yet this is the cornerstone on which rests the presumption of safety of GMOs. Absence of evidence is taken to be evidence of absence. History suggests that this is a fraught presumption. By way of contrast, the patenting of GMOs depends on the antithesis of assumed ‘sameness’. Patenting rests on proven, scrutinised, challengeable and robust tests of difference and novelty. Lightfoot et al. report that transgenic plants exhibit “unexpected changes [that] challenge the usual assumptions of GMO equivalence and suggest genomic, proteomic and metanomic characterization of transgenics is advisable” (1). GMO Milk and Contested Labelling Pesticide company Monsanto markets the genetically engineered hormone rBST (recombinant Bovine Somatotropin; also known as: rbST; rBGH, recombinant Bovine Growth Hormone; and the brand name Prosilac) to dairy farmers who inject it into their cows to increase milk production. This product is not approved for use in many jurisdictions, including Europe, Australia, New Zealand, Canada and Japan. Even Monsanto accepts that rBST leads to mastitis (inflammation and pus in the udder) and other “cow health problems”, however, it maintains that “these problems did not occur at rates that would prohibit the use of Prosilac” (Monsanto). A European Union study identified an extensive list of health concerns of rBST use (European Commission). The US Dairy Export Council however entertain no doubt. In their background document they ask “is milk from cows treated with rBST safe?” and answer “Absolutely” (USDEC). Meanwhile, Monsanto’s website raises and answers the question: “Is the milk from cows treated with rbST any different from milk from untreated cows? No” (Monsanto). Injecting cows with genetically modified hormones to boost their milk production remains a contested practice, banned in many countries. It is the claimed equivalence that has kept consumers of US dairy products in the dark, shielded rBST dairy farmers from having to declare that their milk production is GMO-enhanced, and has inhibited non-GMO producers from declaring their milk as non-GMO, non rBST, or not hormone enhanced. This is a battle that has simmered, and sometimes raged, for a decade in the US. Finally there is a modest victory for consumers: the Pennsylvania Department of Agriculture (PDA) requires all labels used on milk products to be approved in advance by the department. The standard issued in October 2007 (PDA, “Standards”) signalled to producers that any milk labels claiming rBST-free status would be rejected. This advice was rescinded in January 2008 with new, specific, department-approved textual constructions allowed, and ensuring that any “no rBST” style claim was paired with a PDA-prescribed disclaimer (PDA, “Revised Standards”). However, parsimonious labelling is prohibited: No labeling may contain references such as ‘No Hormones’, ‘Hormone Free’, ‘Free of Hormones’, ‘No BST’, ‘Free of BST’, ‘BST Free’,’No added BST’, or any statement which indicates, implies or could be construed to mean that no natural bovine somatotropin (BST) or synthetic bovine somatotropin (rBST) are contained in or added to the product. (PDA, “Revised Standards” 3) Difference claims are prohibited: In no instance shall any label state or imply that milk from cows not treated with recombinant bovine somatotropin (rBST, rbST, RBST or rbst) differs in composition from milk or products made with milk from treated cows, or that rBST is not contained in or added to the product. If a product is represented as, or intended to be represented to consumers as, containing or produced from milk from cows not treated with rBST any labeling information must convey only a difference in farming practices or dairy herd management methods. (PDA, “Revised Standards” 3) The PDA-approved labelling text for non-GMO dairy farmers is specified as follows: ‘From cows not treated with rBST. No significant difference has been shown between milk derived from rBST-treated and non-rBST-treated cows’ or a substantial equivalent. Hereinafter, the first sentence shall be referred to as the ‘Claim’, and the second sentence shall be referred to as the ‘Disclaimer’. (PDA, “Revised Standards” 4) It is onto the non-GMO dairy farmer alone, that the costs of compliance fall. These costs include label preparation and approval, proving non-usage of GMOs, and of creating and maintaining an audit trail. In nearby Ohio a similar consumer versus corporatist pantomime is playing out. This time with the Ohio Department of Agriculture (ODA) calling the shots, and again serving the GMO industry. The ODA prescribed text allowed to non-GMO dairy farmers is “from cows not supplemented with rbST” and this is to be conjoined with the mandatory disclaimer “no significant difference has been shown between milk derived from rbST-supplemented and non-rbST supplemented cows” (Curet). These are “emergency rules”: they apply for 90 days, and are proposed as permanent. Once again, the onus is on the non-GMO dairy farmers to document and prove their claims. GMO dairy farmers face no such governmental requirements, including no disclosure requirement, and thus an asymmetric regulatory impost is placed on the non-GMO farmer which opens up new opportunities for administrative demands and technocratic harassment. Levidow et al. argue, somewhat Eurocentrically, that from its 1990s adoption “as the basis for a harmonized science-based approach to risk assessment” (26) the concept of “substantial equivalence” has “been recast in at least three ways” (58). It is true that the GMO debate has evolved differently in the US and Europe, and with other jurisdictions usually adopting intermediate positions, yet the concept persists. Levidow et al. nominate their three recastings as: firstly an “implicit redefinition” by the appending of “extra phrases in official documents”; secondly, “it has been reinterpreted, as risk assessment processes have … required more evidence of safety than before, especially in Europe”; and thirdly, “it has been demoted in the European Union regulatory procedures so that it can no longer be used to justify the claim that a risk assessment is unnecessary” (58). Romeis et al. have proposed a decision tree approach to GMO risks based on cascading tiers of risk assessment. However what remains is that the defects of the concept of “substantial equivalence” persist. Schauzu identified that: such decisions are a matter of “opinion”; that there is “no clear definition of the term ‘substantial’”; that because genetic modification “is aimed at introducing new traits into organisms, the result will always be a different combination of genes and proteins”; and that “there is no general checklist that could be followed by those who are responsible for allowing a product to be placed on the market” (2). Benchmark for Further Food Novelties? The discourse, contestation, and debate about “substantial equivalence” have largely focussed on the introduction of GMOs into food production processes. GM can best be regarded as the test case, and proof of concept, for establishing “substantial equivalence” as a benchmark for evaluating new and forthcoming food technologies. This is of concern, because the concept of “substantial equivalence” is scientific hokum, and yet its persistence, even entrenchment, within regulatory agencies may be a harbinger of forthcoming same-but-different debates for nanotechnology and other future bioengineering. The appeal of “substantial equivalence” has been a brake on the creation of GMO-specific regulations and on rigorous GMO testing. The food nanotechnology industry can be expected to look to the precedent of the GMO debate to head off specific nano-regulations and nano-testing. As cloning becomes economically viable, then this may be another wave of food innovation that muddies the regulatory waters with the confused – and ultimately self-contradictory – concept of “substantial equivalence”. Nanotechnology engineers particles in the size range 1 to 100 nanometres – a nanometre is one billionth of a metre. This is interesting for manufacturers because at this size chemicals behave differently, or as the Australian Office of Nanotechnology expresses it, “new functionalities are obtained” (AON). Globally, government expenditure on nanotechnology research reached US$4.6 billion in 2006 (Roco 3.12). While there are now many patents (ETC Group; Roco), regulation specific to nanoparticles is lacking (Bowman and Hodge; Miller and Senjen). The USFDA advises that nano-manufacturers “must show a reasonable assurance of safety … or substantial equivalence” (FDA). A recent inventory of nano-products already on the market identified 580 products. Of these 11.4% were categorised as “Food and Beverage” (WWICS). This is at a time when public confidence in regulatory bodies is declining (HRA). In an Australian consumer survey on nanotechnology, 65% of respondents indicated they were concerned about “unknown and long term side effects”, and 71% agreed that it is important “to know if products are made with nanotechnology” (MARS 22). Cloned animals are currently more expensive to produce than traditional animal progeny. In the course of 678 pages, the USFDA Animal Cloning: A Draft Risk Assessment has not a single mention of “substantial equivalence”. However the Federation of Animal Science Societies (FASS) in its single page “Statement in Support of USFDA’s Risk Assessment Conclusion That Food from Cloned Animals Is Safe for Human Consumption” states that “FASS endorses the use of this comparative evaluation process as the foundation of establishing substantial equivalence of any food being evaluated. It must be emphasized that it is the food product itself that should be the focus of the evaluation rather than the technology used to generate cloned animals” (FASS 1). Contrary to the FASS derogation of the importance of process in food production, for consumers both the process and provenance of production is an important and integral aspect of a food product’s value and identity. Some consumers will legitimately insist that their Kalamata olives are from Greece, or their balsamic vinegar is from Modena. It was the British public’s growing awareness that their sugar was being produced by slave labour that enabled the boycotting of the product, and ultimately the outlawing of slavery (Hochschild). When consumers boycott Nestle, because of past or present marketing practices, or boycott produce of USA because of, for example, US foreign policy or animal welfare concerns, they are distinguishing the food based on the narrative of the food, the production process and/or production context which are a part of the identity of the food. Consumers attribute value to food based on production process and provenance information (Paull). Products produced by slave labour, by child labour, by political prisoners, by means of torture, theft, immoral, unethical or unsustainable practices are different from their alternatives. The process of production is a part of the identity of a product and consumers are increasingly interested in food narrative. It requires vigilance to ensure that these narratives are delivered with the product to the consumer, and are neither lost nor suppressed. Throughout the GM debate, the organic sector has successfully skirted the “substantial equivalence” debate by excluding GMOs from the certified organic food production process. This GMO-exclusion from the organic food stream is the one reprieve available to consumers worldwide who are keen to avoid GMOs in their diet. The organic industry carries the expectation of providing food produced without artificial pesticides and fertilizers, and by extension, without GMOs. Most recently, the Soil Association, the leading organic certifier in the UK, claims to be the first organisation in the world to exclude manufactured nonoparticles from their products (Soil Association). There has been the call that engineered nanoparticles be excluded from organic standards worldwide, given that there is no mandatory safety testing and no compulsory labelling in place (Paull and Lyons). The twisted rhetoric of oxymorons does not make the ideal foundation for policy. Setting food policy on the shifting sands of “substantial equivalence” seems foolhardy when we consider the potentially profound ramifications of globally mass marketing a dysfunctional food. If there is a 2×2 matrix of terms – “substantial equivalence”, substantial difference, insubstantial equivalence, insubstantial difference – while only one corner of this matrix is engaged for food policy, and while the elements remain matters of opinion rather than being testable by science, or by some other regime, then the public is the dupe, and potentially the victim. “Substantial equivalence” has served the GMO corporates well and the public poorly, and this asymmetry is slated to escalate if nano-food and clone-food are also folded into the “substantial equivalence” paradigm. Only in Orwellian Newspeak is war peace, or is same different. It is time to jettison the pseudo-scientific doctrine of “substantial equivalence”, as a convenient oxymoron, and embrace full disclosure of provenance, process and difference, so that consumers are not collateral in a continuing asymmetric knowledge war.
