Abstract (sommario):

In the present study, the profitability of a dairy-farm case study evaluated over the period 2003–2004 to 2014–2015 was compared with the performance of other dairy farms and other non-agricultural investments over the same time. Investments are generally made on the expectation that a net return will be earned that justifies using capital in one particular way rather than an alternative way. The expected, and actual, returns from capital invested in different assets will differ according to the risks involved. Investors choose an investment, and mixes of investments, that align with their goals, preferences for risk and anticipated returns over time. Dairy farming involves investing in assets, such as land and improvements, water, livestock, plant and equipment, and people, which are managed to produce milk and ultimately to earn a competitive return on capital. With uncertain seasonal conditions, fluctuating costs and prices, declining terms of trade, wide ranges of equity and management abilities, and a steady decline in the number of commercial farm businesses, it may be tempting to presume that investing in farming, and dairy farming in particular, is a hard road, leading to lower and more variable returns than investing in non-agricultural investment opportunities in the economy. This need not be the case. Analysis of how a dairy business in northern Victoria performed from 2003–2004 to 2014–2015 showed that this farm did well compared with (i) other dairy businesses in Victoria and (ii) alternative investments, such as shares, bonds and property, over the same time. Compound annual return to capital for the dairy farm over the 12 years studied was 12.4% (real, before tax). Over half the return came from the farming operations and the remainder came from owning assets that appreciated in value, particularly in this case, water. The dairy business that was studied was well managed and earned higher annual average returns than the average returns of investments with similar risk elsewhere in the economy, such as shares, and matched it with the best performing of these alternative investments.

Abstract (sommario):

This paper explores some of the factors that may contribute to the sustainable use of water on irrigated dairy farms in Victoria, Australia. The paper begins with a discussion of the principles of sustainable water use as they would apply to dairy farms in the Gippsland region of Victoria. A series of indicators are used to link aspects of sustainable water use at a regional scale, and the observable trends are discussed. Of particular interest is the way that local river systems contribute to the dairy industry in this region and the aspects of dairying and other significant regional factors that may be impacting on the sustainability of river systems in this area. The indicators are structured and analysed using the Pressure-State-Response (PSR) framework developed by the OECD, most commonly used in State of the Environment reporting. The trends highlighted by the indicator set are discussed in terms of the implications that current patterns of water use may have for possible shifts towards more sustainable water use on individual dairy farms in Gippsland.

Abstract (sommario):

Studies have suggested that traditional gender identity constructions of farmers tend to accompany conventional methods of farming and so are implicated in stalling the transition to sustainable agriculture. This article attempts to build on this work by exploring how young male farmers construct their masculine identities and how those identity constructions shape and are shaped by their farming practices and the social conditions in which those farming practices are carried out. Reflexivity is a significant part of this process. This exploratory study is based on focus group discussions conducted in one locality in Northern Victoria, among young male dairy farmers. Analysis of the findings supports the existence of a traditional-modern dualism in rural masculine identities. What is also evident is that more open and flexible masculine identities are emerging among young farmers, suggesting that existing tensions in agriculture situated at the nexus of alternative farming practices and traditional agrarian ideology might be a catalyst for change toward more equitable gender relations and sustainable ways of farming.

Abstract (sommario):

Around the world, dairy production continues to intensify, with farmers increasing stocking rates, feeding more supplements, and transitioning into fully housed systems. Dairy production in Victoria is no exception and farmers are starting a move towards intensive (i.e. permanently housed) dairy operations. Challenges associated with these transformations have included difficulties, or failure, to obtain planning approval and public concern around the effect of intensive developments on environmental degradation, animal welfare and industry image. We examined current land-use planning provisions, environmental requirements, animal-welfare regulations, industry guidelines and codes of practice for their applicability and suitability to the implementation of intensive dairy-production operations, particularly large-scale ones, in Victoria, Australia. Our aim was to clearly identify factors that have the potential to hinder the growth and expansion of existing dairy-production systems into intensive operations, and the establishment of new intensive dairy enterprises. The majority of legislation examined posed no obstacles to the development of large-scale intensive dairy operations. New definitions for intensive livestock production and the inclusion of an intensive dairy-farm category in the State planning provisions will reduce current confusion across and within planning departments. A standard methodology to determine separation distances is required and a code for intensive dairy farming would greatly assist with the planning-approval process. Many advisory publications fall short when applied to intensive dairy operations as they are currently written for pasture-based farms with limited infrastructure for regularly feeding or housing large herds of >700 cows.

Abstract (sommario):

White clover (Trifolium repens L.) continues to play a pivotal role in the Australasian pastoral industry, despite increased use of nitrogen fertiliser on farms. Improved white clovers for dairy farming must be well adapted to the farm systems they are intended for, including increased rates of fertiliser nitrogen, higher stocking rates and access to irrigation. The breeding objective was to develop a white clover cultivar in evaluation systems that simulate modern farming practices, and test that cultivar in both New Zealand and Australia for adaptation and agronomic merit. This included breeding and early generation evaluation at research farms in the Manawatu and Waikato, with subsequent evaluations in these locations and farms in Southland and Victoria, Australia. This resulted in 'Grasslands Legacy', a new large leaved white clover cultivar bred for New Zealand and eastern temperate Australian pastures, which has shown significant (P

Abstract (sommario):

Ten paired irrigated dairy farms under biodynamic (BD) and conventional (CV) management were compared over a 4-year period (1991–94). The paired farms were located in the irrigation districts of northern Victoria and southern New South Wales and were matched for soil type, climate, cattle breed and farm area. Farms had been practising BD principles for an average of 16 years before the commencement of the study and had not received phosphorus (P) fertiliser for an average of 17 years. The effects of farm management on soil chemical and biological properties and the nutritive properties and botanical composition of pasture were examined at varying sampling times during the study. Soil Olsen extractable P concentrations were consistently 2–3 times higher under CV management at various sampling depths (mean = 22 mg/kg, 0–10 cm), and were generally marginal under BD management in the surface 10 cm (mean = 8.5 mg/kg). Low soil extractable P concentrations were also reflected in consistently lower mean pasture P concentrations under BD management (0.25 compared with 0.35% on CV farms). Lower soil and pasture P concentrations under BD management were the result of a large negative P balance across BD farms (–17 kg P/ha.year). A mean negative P balance under BD management was a result of low P imports (2 kg P/ha.year) in comparison with large quantities of P (19 kg P/ha.year) effectively lost from the farming system through animal products, estimated losses in water runoff and slowly reversible soil P reactions. These results suggest that greater P imports are required to ensure the future sustainability of BD dairy pasture farming systems. There were few differences in soil biological properties, with earthworm weights significantly higher under CV management, but no difference in soil organic carbon, humus concentration, the weight of the organic mat or microbial biomass, between the two management systems.

Abstract (sommario):

Excess nutrients are challenging the long-term sustainability of grazing-based dairy farming. Whole-farm nutrient-mass balance (NMB) is a well recognised approach to improve on-farm nutrient management decisions. In the present paper, we use a standardised approach for quantifying NMB on grazing-based dairy farms, using a newly developed online tool. Preliminary evaluation, using selected farm data from a previous Australia-wide dairy-farm nutrient study, demonstrated highly comparable estimates of farm area, nutrient fluxes and NMB, with substantial efficiencies in time and sample analysis. Nutrient mass balances were also determined on 16 diverse dairy farms across the five major dairy regions of Victoria, Australia. These results highlighted the importance of purchased feed, fertiliser and milk sales, as major sources of nutrient inputs and outputs, with whole-farm NMB for the 16 dairy farms ranging from 185 to 481 kg/ha for nitrogen, 12–59 kg/ha for phosphorus, 9–244 kg/ha for potassium and –6–55 kg/ha for sulfur. Current industry adoption of the NMB tool has confirmed the benefits of a standardised and efficient collation and processing of readily available farm data to inform nutrient management decisions on commercial dairy farms. We suggest that the standardised assessment of nutrient fluxes, balances and efficiency, as well as feed- and milk-production performance at the whole-farm level, provides dairy farmers, farm advisors and industry and policy analysts with the ability to determine industry-wide goals and improve environmental performance.

Abstract (sommario):

A survey of 170 randomly selected, irrigated, dairy farms in northern Victoria and 9 in southern New South Wales was conducted to examine and benchmark the key factors influencing water-use efficiency. Water-use efficiency was defined as the amount of milk (kg milk fat plus protein) produced from pasture per megalitre of water (irrigation plus effective rainfall). Information on water-use, milk production, supplementary feeding, farm size and type, pasture management, and irrigation layout and management was collected for each farm by personal interview for the 1994–95 and 1995–96 seasons. The farms were ranked in the order of water-use efficiency with the average farm compared with the highest and lowest 10% of farms. The range in water-use efficiency was 25–115 kg milk fat plus protein/ML, with the highest 10% averaging 94 kg/ML and the lowest 10% averaging 35 kg/ML. The large range in water-use efficiency indicated potential for substantial improvement on many farms. The high water-use efficiency farms, when compared with the low group: (i) produced a similar amount of milk from less water (387 v. 572 ML) (P<0.05), less land (48 v. 83 ha) (P< 0.05) and a similar number of cows (152 v. 143 cows); (ii) had higher estimated pasture consumption per hectare (11.5 v. 5.5 t DM/ha) (P<0.01) and per megalitre (1.0 v. 0.5 t DM/ML) (P<0.01); (iii) had higher stocking rates (3.2 v. 1.8 cows/ha) (P<0.01); (iv) used higher rates of nitrogen fertiliser (59 v. 18 kg N/ha.year) (P<0.05) and tended to use more phosphorus fertiliser (64 v. 34 kg P/ha.year) (P<0.10); (v) used similar levels of supplementary feed (872 v. 729 kg concentrates/cow); (vi) had higher milk production per cow (396 v. 277 kg fat plus protein) (P<0.05); and (vii) directed a higher proportion of the estimated energy consumed by cows into milk production (53 v. 46%) (P<0.05). The survey data confirmed that irrigated dairy farm systems are complex and variable. For example, the amount of feed brought in from outside the milking area varied from 0 to 74% of the estimated total energy used by a milking herd. There was a large range in the level of supplement input amongst the farms in the high water-use efficiency group, and in the low water-use efficiency group. This indicates that the management of the farming system has a greater impact on the efficiency of water-use on irrigated dairy farms, than the type of system. The data from the survey provide information for individual farms, a measure of the water-use efficiency of the industry, and an indication of the quality of regional land and water resources.

Abstract (sommario):

p>Agricultural production in Victoria includes the dairy, lamb and mutton, grains and perennial and annual horticultural sectors, with Victorian farmers contributing a major proportion of the Australian production total in many of these sectors. All these industries are exposed in different ways to weather and climate extremes. With projected warming of approximately 0.8°C by 2030 and by 1.4–2.7°C by 2070 (emissions dependent), and most climate models indicating reduced rainfall for the Victorian region (median of model results projecting a reduction of 4% by 2030 and 6%–11% by 2070; emissions dependent), a range of sectorspecific impacts could result. Increases in extreme events, such as heatwaves (e.g. for Mildura, days >35°C could nearly double from 32 to 59 annually by 2070), bushfires and drought, as well as an increased chance of extreme rainfall are all anticipated. Increasing frequencies of extreme events have the potential to affect agricultural production more than changes to the mean climate. For example, the exceptional heatwave that occurred in south-eastern Australia during January and February 2009 resulted in unprecedented impacts, with significant heat-stress related crop losses reported at many sites. Flooding in 2011 was also very costly to Victorian farmers with many crops being lost in the floodwaters and reduced agricultural production costing an estimated Au$500–600 million. Responses to climate variability already practised by the farming sector will inform some adaptation options that will assist farmers to cope in an increasingly challenging environment. As well as taking advantage of their underlying resilience, initiatives aimed at increasing the adaptive capacity of farmers are being implemented at many levels in agricultural communities.

Abstract (sommario):

The CO2CRC Otway Project continues to demonstrate that carbon capture and storage is a viable option for CO2 mitigation. The CO2CRC Otway Project is Australia’s first CO2 demonstration project, with two projects completed, involving geological storage of some 80000 tonnes of CO2 over the past 10 years. The project was initially authorised for a single stage with a finite life, but the growing requirements of the global carbon capture and storage community required further research on carbon capture and storage technologies and behaviour (via Stages 2 and 3), and so the project was extended. CO2CRC has undertaken 360-degree stakeholder engagement processes throughout the project, regularly consulting with regulators, governments, industry, partners, researchers and the community. This has been especially important as the project changed, operating in a niche space between Victorian environment, petroleum and water Acts. This process has allowed CO2CRC to contribute to alignment efforts within regulatory bodies, to enhance regulations to cover project activities, ensuring best practices are documented and observed to the satisfaction of the regulators and wider community. The Otway Basin in south-west Victoria is a region not immune to broader community concerns regarding the oil and gas and other industries. The surrounding area is predominately dairy farming, with locals relying heavily on the aquifers beneath their land. Although such a backdrop suggests potentially high levels of concern and scrutiny, especially when projects necessitate drilling or other invasive activities, the project has maintained strong local stakeholder engagement and support due to ongoing implementation and evaluation of the stakeholder management processes.

Abstract (sommario):

In response to increasing concern about environmental quality, water authorities in many countries are imposing legislation limiting phosphorus (P) concentrations in water, which is having an impact on farming practice. This experiment investigated the agronomic effects and runoff losses associated with different forms of P fertiliser applied to an irrigated dairy pasture (soils were Vertic Calcic Red Chromosols; average Olsen P, 50 mg P/kg) in north-central Victoria, Australia. Single superphosphate (SSP), a sulfurised diammonium phosphate, or partially acidulated phosphate rock was surface-applied at 50 kg P/ha in March 2005 to a border-check, flood-irrigated dairy pasture (ryegrass–white clover) ten days before a scheduled irrigation. Dissolved reactive P (DRP) and total P (TP) were measured in runoff from whole bays on one replicate and from microplots on all three replicates for a period of 9 weeks. In all runoff events and all treatments, concentrations of DRP and TP in runoff greatly exceeded water quality guidelines for acceptable limits (0.045 mg P/L). The SSP resulted in significantly higher concentrations of P in runoff than the less water-soluble fertilisers. Even after the fifth irrigation, runoff from all fertilisers still exceeded the control. These results suggest that: (i) P fertilisers should not be applied in high-risk situations as insurance against yield loss; (ii) the current recommendation of withholding irrigation for 3 days after fertiliser application is insufficient to prevent potentially significant losses occurring; and (iii) runoff losses were dependent on the type of fertiliser applied, with a smaller proportion of P applied as sulfurised DAP lost in runoff.

Abstract (sommario):

The profitability of dairy businesses in southern Australia is closely related to the amount of feed consumed from perennial ryegrass-dominant pasture. Historically, the dairy industry has relied on improvements in pasture productivity and utilisation to support profitable increases in stocking rate and milk production per hectare. However, doubts surround the extent to which the industry can continue to rely on perennial ryegrass technology to provide the necessary productivity improvements required into the future. This paper describes the design and management of a dairy systems experiment at Terang in south-west Victoria (780-mm average annual rainfall) conducted over four lactations (June 2005–March 2009) to compare the production and profitability of two forage base options for non-irrigated dairy farms. These options were represented by two self-contained farmlets each milking 36 mixed-age, autumn-calving Holstein-Friesian cows at peak: (1) well managed perennial ryegrass pasture (‘Ryegrass Max’, or ‘RM’); and (2) perennial ryegrass plus complementary forages (‘CF’) including 15% of farmlet area under double cropping with annual species (winter cereal grown for silage followed by summer brassica for grazing on the same land) and an average of 25% of farmlet area in perennial pasture based on tall fescue for improved late spring–early summer feed supply. The design of these systems was informed by farming systems models (DairyMod, UDDER and Redsky), which were used to estimate the effects of introducing different forage options on farm profitability. The design of the CF system was selected based on modelled profitability increases assuming that all forage components could be managed to optimise forage production and be effectively integrated to optimise milk production per cow. Using the historical ‘average’ pasture growth curve for the Terang district and a mean milk price of $3.71 per kg milk solids, the models estimated that the return on assets of the RM and CF systems would be 9.4 and 15.0%, respectively. The objectives of the experiment described here were to test whether or not such differences in profitability could be achieved in practice, and to determine the risks associated with including complementary forages on a substantial proportion of the effective farm area. Key results of the experiment are presented in subsequent papers.

Abstract (sommario):

SUMMARYA recent outbreak of Q fever was linked to an intensive goat and sheep dairy farm in Victoria, Australia, 2012-2014. Seventeen employees and one family member were confirmed with Q fever over a 28-month period, including two culture-positive cases. The outbreak investigation and management involved a One Health approach with representation from human, animal, environmental and public health. Seroprevalence in non-pregnant milking goats was 15% [95% confidence interval (CI) 7–27]; active infection was confirmed by positive quantitative PCR on several animal specimens. Genotyping ofCoxiella burnetiiDNA obtained from goat and human specimens was identical by two typing methods. A number of farming practices probably contributed to the outbreak, with similar precipitating factors to the Netherlands outbreak, 2007-2012. Compared to workers in a high-efficiency particulate arrestance (HEPA) filtered factory, administrative staff in an unfiltered adjoining office and those regularly handling goats and kids had 5·49 (95% CI 1·29–23·4) and 5·65 (95% CI 1·09–29·3) times the risk of infection, respectively; suggesting factory workers were protected from windborne spread of organisms. Reduction in the incidence of human cases was achieved through an intensive human vaccination programme plus environmental and biosecurity interventions. Subsequent non-occupational acquisition of Q fever in the spouse of an employee, indicates that infection remains endemic in the goat herd, and remains a challenge to manage without source control.

Abstract (sommario):

There has been increasing recognition that for regional competitiveness in rural areas there needs to be a focus on sustainable farming initiatives especially for family farms that are competing with global conglomerates. Family farms, whilst declining in number, are the purpose of this paper studying the rural entrepreneurship in family farms as they are at the heart of rural communities and the overall agricultural industry and comprise a high percentage of total farms. This paper takes a case study approach using in-depth semi structured interviews to delve into the types of entrepreneurial strategies that are distinctive of family farms in terms of their sustainability approach to farming. Dairy farms in the West Victorian area of Australia are studied and the findings suggest that family farms can increase their regional competitiveness and international standing by focusing on their collaborative, social and sustainable entrepreneurial strategies.

Testo completo

Abstract (sommario):

This review examines the potential for extended lactations on Victorian dairy farms in the context of (i)�the advantages and disadvantages of existing seasonal milk production systems; (ii) projected future changes to Victorian dairy farming; (iii) the mechanics of extended lactations; (iv) the change in costs associated with extended lactations; and (v) how extended lactations might be successfully implemented. Traditionally, Victorian dairying has been characterised by seasonal, low input, pasture-based milk production reliant on family labour. Successful implementation of this type of milk production system requires cows to calve in accordance with seasonal pasture supply. Recently a number of economic (static or falling milk prices), management (larger herds, increased labour expense, lower labour availability) and social pressures (animal welfare and environmental regulation) have emerged that question the viability of pasture-based dairying in a number of countries including Australia. Some of these threats to dairying may increase the attractiveness of systems that exploit the production potential of high yielding cows in larger herds, with increased supplementation of pasture-based diets over extended lactations. It is generally concluded that 12-month calving intervals are the most economic, based on the shape of the lactation curve and the perceived costs of extended lactations. However, these fundamentals have been changed by years of intensive selection for high milk production and the recent implementation of new management techniques such as Bovine somatotrophin, total mixed rations and increased milking frequency. Modern high yielding cows can maintain high daily yields for a much longer proportion of lactation than previously, but these cows are also largely unsuited to seasonal production systems due to a prolonged period of negative energy balance after calving and consequent low fertility. We have identified that calving and pregnancy incur substantial costs that are often hidden but need to be accounted for in valid economic comparisons. It is evident that seasonal pasture-based dairying requires disciplined management where certain tasks must be achieved in a timely manner if the system is to operate efficiently. Where the system does break down, often due to infertility for example, new management approaches are required. It is of concern that farmers may adopt a default position of extended lactations without realising or exploiting the potential benefits. Among the advantages of extended lactation management would be a more even spread in labour requirements, input costs and income across the year. In conclusion, extended lactations are a suitable option for some Victorian dairy enterprises. That suitability will depend on a number of factors; particularly, cow milk production potential, ability to grow pasture or feed supplements economically, management expertise, environmental constraints, herd size and labour availability.

Abstract (sommario):

Context Social aspects of livestock farming systems, including farm workforce and how work is organised, have received less research attention than the biophysical and technological aspects. This constrains understanding of social challenges to the sustainability of livestock systems, such as farm labour shortages, farmers’ overwork, the undesirability of farming careers, workforce and skills changes linked to new technologies, and the connections of all these to farm performance and profitability. Aims We introduce and test the applicability and utility in the Australian context of a method developed in France for assessing work organisation: The Work Assessment Method (WAM). The WAM goes beyond standard labour productivity metrics, such as total labour cost or livestock units per worker, to examine different types of work (routine, seasonal), who does the work (owner–managers, employees, contractors) and how these change seasonally. A measure of social sustainability (‘calculated time available’) is a key feature. Methods We conducted the first Australian trial of the WAM on two Victorian dairy farms. Through facilitated discussions between participating farmers and the research team, we evaluated the utility of the method, and identified requirements to adapt it for larger, pasture-based dairy systems. Key results The WAM was applied successfully on the pilot farms, despite differences in farm systems between France and Australia. The method characterised in detail the sources of overwork for each farm, enabling discussion of how the social sustainability and overall performance of the farms could be improved. The participating farmers reported that the method provided insights that were not available from current financial and physical analyses. Conclusions The WAM shows potential for supporting farmers, advisors and researchers in work aimed at improving farm social sustainability and profitability, but requires adaptation to suit Australian conditions. A larger exploratory study applying the WAM on additional dairy farms, and on mixed farms, is suggested. Implications This study provides a strong foundation for further research to develop the WAM as a useful research and advisory tool for Australian livestock production systems.

<p>With increasing population, coupled with land shortage and weather variations, wetlands in Uganda have continued to face degradation due to mainly conversion for agricultural, industrial and settlement purposes. The objective of this study was to determine the spatial and temporal wetland use/cover changes and local perceptions attributed to these changes. The study utilized three sets of ortho-rectified and cloud free Landsat TM/ETM+/MSS temporal images (30 m) of 1986, 2000 and 2011. The classification procedures were carried out using an Integrated Land and Water Information System (ILWIS) software version 3.7. A wetland classification system for Uganda developed by the National Biomass Study, 2003 was adopted to describe the wetland use/cover types. The classified images were validated in a ground truthing exercise using Global Positioning System (GPS) to improve on the classification accuracy. Key informant interviews and focus group discussions were conducted with communities adjacent to the wetlands in each of three of the ten Ugandan agro-ecological zones to determine the underlying drivers of wetland use/cover changes, while household interviews generated information on local perceptions of the changes. Significant changes were mainly observed in wetland use/cover between 1986 and 2011. Major factors responsible for these changes were subsistence farming due to intensification of growing paddy rice in Kyoga plains, an influx of migrants who accessed wetlands for daily subsistence (livestock grazing) in South western farmlands and proximity to urban centres in the Lake Victoria Crescent. In all the sampled agro-ecological zones, increased crop farming in wetlands was due to changing opportunities created by existent large markets for wetland crops. Majority (60%) of the local people perceived wetlands in their proximity to have undergone high degradation within the last 10 years, and to have declined in quantity and quality of vegetation, soil fertility and water levels. There was a noticeable variation across the sampled agro-ecological zones, with the highest proportion of local communities perceiving degradation being in Kyoga plains (76%), followed by Lake Victoria crescent (63%) and South-western farmlands (41%). Locally perceived threats to wetlands were mainly from crop growing that accounted for 33% of the frequency of mentioned threats, collection of wetland resources (30%), and prolonged floods and droughts (12%). This study confirms the importance of economic opportunities from new market outlets and migration in its various forms as key factors in land use change, especially at timescales of a couple of decades.<strong></strong></p>

Abstract (sommario):

Assessment of the prospects of introduced and created varieties of Lavandula angustifolia L. in the conditions of the Southern Steppe in terms of yield and essential oil content in raw materials, as well as the influence of the weather conditions of the year on these economically valuable traits is given. The study included 11 samples of Lavandula angustifolia L. Ecological and phenological observations were carried out for the studied plants. During the period of mass flowering of plants, the crop was recorded. The mass fraction of the essential oil was determined by the Ginsberg method on the Clevenger apparatus. The main results of the multi-year research work on the assessment of collection samples for economic and valuable characteristics of Lavandula angustifolia depending on weather conditions are highlighted. On the basis of the State Enterprise «Experimental Farming “Novokakhov”» of the Institute of ClimateOriented Agriculture of the National Academy of Sciences of Ukraine, collection plots of narrow-leaved lavender samples were established for introductory study and testing in the conditions of the Southern Steppe. For 20 years in this region, Lavandula angustifolia underwent multi-vector study as an ornamental and essential oil crop.During this period, new variety samples and varieties adapted to local conditions were created, which have increased decorative indicators, as well as high yield and mass share of essential oil in raw materials. In particular, Lydia, Victoria and Sinieva Nadiyi varieties, with the following characteristics: plant height, cm — 65, 60.0 and 60.0, respectively; inflorescence length, cm — 8.0, 5.0 and 13.0; number of inflorescences on a plant, pcs. — 95, 230 and 200; number of flowers in an inflorescence, pcs. — 80, 49 and 90; essential oil content, % — 3.0, 3.8 and 3.25; collection of essential oil, kg/ha — 64.0, 83.0 and 71.0; content of linalyl acetate in essential oil, % — 48.0, 34.2 and 20.1; duration of the flowering period, days — 30; inflorescence yield, t/ha — 0.53, 0.55 and 0.55; frost resistance, score (1–9) — 9; resistance against pests, score (1–9): ant (Lasiusnsger) — 9; causative agents of diseases, score (1–9) — 9 — not detected (village Lidia), sora rot — 9 (village Victoria) and not detected (village Sinieva Nadiyi); zoning area — steppe. The period 2016–2021 is of particular interest, considering the study of the adaptability of culture. The weather conditions in the mentioned years differed among themselves in terms of temperature, amount of precipitation and their distribution, etc. Such conditions made it possible to assess comprehensively the influence of the weather conditions on the manifestation of economic and valuable characteristics of collections of lavender samples in this region, including newly created varieties of this valuable culture. Observations revealed deviations in the passage of phenological phases and the accumulation of essential oil. The minimum yields and essential oil content of all samples occurred in 2016, which is associated with a sharp drop in temperature and freezing of plant shoots. The maximum yield of raw materials was recorded in 2020, which is associated with the optimal amount of precipitation in the phase of growth and budding. The maximum indicators of the mass fraction of essential oil in raw materials were recorded in 2018, which is associated with high average daily temperatures and the absence of precipitation and dry weather during flowering. The results of the long-term evaluation of the samples of narrow-leaved lavender L. angustifolia based on the main economic and valuable characteristics indicate the prospects of industrial cultivation of the crop in the conditions of the Southern Steppe, and also convincingly prove the presence of genetic material of domestic origin adapted to the conditions of the region.

Abstract (sommario):

Introduction Eating is one of the most quintessential activities of human life. Because of this primacy, eating is, as food anthropologist Sidney Mintz has observed, “not merely a biological activity, but a vibrantly cultural activity as well” (48). This article posits that the current awareness of climate change in the Western world is animating such cultural activity as the Slow Food movement and is, as a result, stimulating what could be seen as an evolutionary change in popular foodways. Moreover, this paper suggests that, in line with modelling provided by the Slow Food example, an increased awareness of the connections of climate change to the social injustices of food production might better drive social change in such areas. This discussion begins by proposing that contemporary foodways—defined as “not only what is eaten by a particular group of people but also the variety of customs, beliefs and practices surrounding the production, preparation and presentation of food” (Davey 182)—are changing in the West in relation to current concerns about climate change. Such modification has a long history. Since long before the inception of modern Homo sapiens, natural climate change has been a crucial element driving hominidae evolution, both biologically and culturally in terms of social organisation and behaviours. Macroevolutionary theory suggests evolution can dramatically accelerate in response to rapid shifts in an organism’s environment, followed by slow to long periods of stasis once a new level of sustainability has been achieved (Gould and Eldredge). There is evidence that ancient climate change has also dramatically affected the rate and course of cultural evolution. Recent work suggests that the end of the last ice age drove the cultural innovation of animal and plant domestication in the Middle East (Zeder), not only due to warmer temperatures and increased rainfall, but also to a higher level of atmospheric carbon dioxide which made agriculture increasingly viable (McCorriston and Hole, cited in Zeder). Megadroughts during the Paleolithic might well have been stimulating factors behind the migration of hominid populations out of Africa and across Asia (Scholz et al). Thus, it is hardly surprising that modern anthropogenically induced global warming—in all its’ climate altering manifestations—may be driving a new wave of cultural change and even evolution in the West as we seek a sustainable homeostatic equilibrium with the environment of the future. In 1962, Rachel Carson’s Silent Spring exposed some of the threats that modern industrial agriculture poses to environmental sustainability. This prompted a public debate from which the modern environmental movement arose and, with it, an expanding awareness and attendant anxiety about the safety and nutritional quality of contemporary foods, especially those that are grown with chemical pesticides and fertilizers and/or are highly processed. This environmental consciousness led to some modification in eating habits, manifest by some embracing wholefood and vegetarian dietary regimes (or elements of them). Most recently, a widespread awareness of climate change has forced rapid change in contemporary Western foodways, while in other climate related areas of socio-political and economic significance such as energy production and usage, there is little evidence of real acceleration of change. Ongoing research into the effects of this expanding environmental consciousness continues in various disciplinary contexts such as geography (Eshel and Martin) and health (McMichael et al). In food studies, Vileisis has proposed that the 1970s environmental movement’s challenge to the polluting practices of industrial agri-food production, concurrent with the women’s movement (asserting women’s right to know about everything, including food production), has led to both cooks and eaters becoming increasingly knowledgeable about the links between agricultural production and consumer and environmental health, as well as the various social justice issues involved. As a direct result of such awareness, alternatives to the industrialised, global food system are now emerging (Kloppenberg et al.). The Slow Food (R)evolution The tenets of the Slow Food movement, now some two decades old, are today synergetic with the growing consternation about climate change. In 1983, Carlo Petrini formed the Italian non-profit food and wine association Arcigola and, in 1986, founded Slow Food as a response to the opening of a McDonalds in Rome. From these humble beginnings, which were then unashamedly positing a return to the food systems of the past, Slow Food has grown into a global organisation that has much more future focused objectives animating its challenges to the socio-cultural and environmental costs of industrial food. Slow Food does have some elements that could be classed as reactionary and, therefore, the opposite of evolutionary. In response to the increasing homogenisation of culinary habits around the world, for instance, Slow Food’s Foundation for Biodiversity has established the Ark of Taste, which expands upon the idea of a seed bank to preserve not only varieties of food but also local and artisanal culinary traditions. In this, the Ark aims to save foods and food products “threatened by industrial standardization, hygiene laws, the regulations of large-scale distribution and environmental damage” (SFFB). Slow Food International’s overarching goals and activities, however, extend far beyond the preservation of past foodways, extending to the sponsoring of events and activities that are attempting to create new cuisine narratives for contemporary consumers who have an appetite for such innovation. Such events as the Salone del Gusto (Salon of Taste) and Terra Madre (Mother Earth) held in Turin every two years, for example, while celebrating culinary traditions, also focus on contemporary artisanal foods and sustainable food production processes that incorporate the most current of agricultural knowledge and new technologies into this production. Attendees at these events are also driven by both an interest in tradition, and their own very current concerns with health, personal satisfaction and environmental sustainability, to change their consumer behavior through an expanded self-awareness of the consequences of their individual lifestyle choices. Such events have, in turn, inspired such events in other locations, moving Slow Food from local to global relevance, and affecting the intellectual evolution of foodway cultures far beyond its headquarters in Bra in Northern Italy. This includes in the developing world, where millions of farmers continue to follow many traditional agricultural practices by necessity. Slow Food Movement’s forward-looking values are codified in the International Commission on the Future of Food and Agriculture 2006 publication, Manifesto on the Future of Food. This calls for changes to the World Trade Organisation’s rules that promote the globalisation of agri-food production as a direct response to the “climate change [which] threatens to undermine the entire natural basis of ecologically benign agriculture and food preparation, bringing the likelihood of catastrophic outcomes in the near future” (ICFFA 8). It does not call, however, for a complete return to past methods. To further such foodway awareness and evolution, Petrini founded the University of Gastronomic Sciences at Slow Food’s headquarters in 2004. The university offers programs that are analogous with the Slow Food’s overall aim of forging sustainable partnerships between the best of old and new practice: to, in the organisation’s own words, “maintain an organic relationship between gastronomy and agricultural science” (UNISG). In 2004, Slow Food had over sixty thousand members in forty-five countries (Paxson 15), with major events now held each year in many of these countries and membership continuing to grow apace. One of the frequently cited successes of the Slow Food movement is in relation to the tomato. Until recently, supermarkets stocked only a few mass-produced hybrids. These cultivars were bred for their disease resistance, ease of handling, tolerance to artificial ripening techniques, and display consistency, rather than any culinary values such as taste, aroma, texture or variety. In contrast, the vine ripened, ‘farmer’s market’ tomato has become the symbol of an “eco-gastronomically” sustainable, local and humanistic system of food production (Jordan) which melds the best of the past practice with the most up-to-date knowledge regarding such farming matters as water conservation. Although the term ‘heirloom’ is widely used in relation to these tomatoes, there is a distinctively contemporary edge to the way they are produced and consumed (Jordan), and they are, along with other organic and local produce, increasingly available in even the largest supermarket chains. Instead of a wholesale embrace of the past, it is the connection to, and the maintenance of that connection with, the processes of production and, hence, to the environment as a whole, which is the animating premise of the Slow Food movement. ‘Slow’ thus creates a gestalt in which individuals integrate their lifestyles with all levels of the food production cycle and, hence to the environment and, importantly, the inherently related social justice issues. ‘Slow’ approaches emphasise how the accelerated pace of contemporary life has weakened these connections, while offering a path to the restoration of a sense of connectivity to the full cycle of life and its relation to place, nature and climate. In this, the Slow path demands that every consumer takes responsibility for all components of his/her existence—a responsibility that includes becoming cognisant of the full story behind each of the products that are consumed in that life. The Slow movement is not, however, a regime of abstention or self-denial. Instead, the changes in lifestyle necessary to support responsible sustainability, and the sensual and aesthetic pleasure inherent in such a lifestyle, exist in a mutually reinforcing relationship (Pietrykowski 2004). This positive feedback loop enhances the potential for promoting real and long-term evolution in social and cultural behaviour. Indeed, the Slow zeitgeist now informs many areas of contemporary culture, with Slow Travel, Homes, Design, Management, Leadership and Education, and even Slow Email, Exercise, Shopping and Sex attracting adherents. Mainstreaming Concern with Ethical Food Production The role of the media in “forming our consciousness—what we think, how we think, and what we think about” (Cunningham and Turner 12)—is self-evident. It is, therefore, revealing in relation to the above outlined changes that even the most functional cookbooks and cookery magazines (those dedicated to practical information such as recipes and instructional technique) in Western countries such as the USA, UK and Australian are increasingly reflecting and promoting an awareness of ethical food production as part of this cultural change in food habits. While such texts have largely been considered as useful but socio-politically relatively banal publications, they are beginning to be recognised as a valid source of historical and cultural information (Nussel). Cookbooks and cookery magazines commonly include discussion of a surprising range of issues around food production and consumption including sustainable and ethical agricultural methods, biodiversity, genetic modification and food miles. In this context, they indicate how rapidly the recent evolution of foodways has been absorbed into mainstream practice. Much of such food related media content is, at the same time, closely identified with celebrity mass marketing and embodied in the television chef with his or her range of branded products including their syndicated articles and cookbooks. This commercial symbiosis makes each such cuisine-related article in a food or women’s magazine or cookbook, in essence, an advertorial for a celebrity chef and their named products. Yet, at the same time, a number of these mass media food celebrities are raising public discussion that is leading to consequent action around important issues linked to climate change, social justice and the environment. An example is Jamie Oliver’s efforts to influence public behaviour and government policy, a number of which have gained considerable traction. Oliver’s 2004 exposure of the poor quality of school lunches in Britain (see Jamie’s School Dinners), for instance, caused public outrage and pressured the British government to commit considerable extra funding to these programs. A recent study by Essex University has, moreover, found that the academic performance of 11-year-old pupils eating Oliver’s meals improved, while absenteeism fell by 15 per cent (Khan). Oliver’s exposé of the conditions of battery raised hens in 2007 and 2008 (see Fowl Dinners) resulted in increased sales of free-range poultry, decreased sales of factory-farmed chickens across the UK, and complaints that free-range chicken sales were limited by supply. Oliver encouraged viewers to lobby their local councils, and as a result, a number banned battery hen eggs from schools, care homes, town halls and workplace cafeterias (see, for example, LDP). The popular penetration of these ideas needs to be understood in a historical context where industrialised poultry farming has been an issue in Britain since at least 1848 when it was one of the contributing factors to the establishment of the RSPCA (Freeman). A century after Upton Sinclair’s The Jungle (published in 1906) exposed the realities of the slaughterhouse, and several decades since Peter Singer’s landmark Animal Liberation (1975) and Tom Regan’s The Case for Animal Rights (1983) posited the immorality of the mistreatment of animals in food production, it could be suggested that Al Gore’s film An Inconvenient Truth (released in 2006) added considerably to the recent concern regarding the ethics of industrial agriculture. Consciousness-raising bestselling books such as Jim Mason and Peter Singer’s The Ethics of What We Eat and Michael Pollan’s The Omnivore’s Dilemma (both published in 2006), do indeed ‘close the loop’ in this way in their discussions, by concluding that intensive food production methods used since the 1950s are not only inhumane and damage public health, but are also damaging an environment under pressure from climate change. In comparison, the use of forced labour and human trafficking in food production has attracted far less mainstream media, celebrity or public attention. It could be posited that this is, in part, because no direct relationship to the environment and climate change and, therefore, direct link to our own existence in the West, has been popularised. Kevin Bales, who has been described as a modern abolitionist, estimates that there are currently more than 27 million people living in conditions of slavery and exploitation against their wills—twice as many as during the 350-year long trans-Atlantic slave trade. Bales also chillingly reveals that, worldwide, the number of slaves is increasing, with contemporary individuals so inexpensive to purchase in relation to the value of their production that they are disposable once the slaveholder has used them. Alongside sex slavery, many other prevalent examples of contemporary slavery are concerned with food production (Weissbrodt et al; Miers). Bales and Soodalter, for example, describe how across Asia and Africa, adults and children are enslaved to catch and process fish and shellfish for both human consumption and cat food. Other campaigners have similarly exposed how the cocoa in chocolate is largely produced by child slave labour on the Ivory Coast (Chalke; Off), and how considerable amounts of exported sugar, cereals and other crops are slave-produced in certain countries. In 2003, some 32 per cent of US shoppers identified themselves as LOHAS “lifestyles of health and sustainability” consumers, who were, they said, willing to spend more for products that reflected not only ecological, but also social justice responsibility (McLaughlin). Research also confirms that “the pursuit of social objectives … can in fact furnish an organization with the competitive resources to develop effective marketing strategies”, with Doherty and Meehan showing how “social and ethical credibility” are now viable bases of differentiation and competitive positioning in mainstream consumer markets (311, 303). In line with this recognition, Fair Trade Certified goods are now available in British, European, US and, to a lesser extent, Australian supermarkets, and a number of global chains including Dunkin’ Donuts, McDonalds, Starbucks and Virgin airlines utilise Fair Trade coffee and teas in all, or parts of, their operations. Fair Trade Certification indicates that farmers receive a higher than commodity price for their products, workers have the right to organise, men and women receive equal wages, and no child labour is utilised in the production process (McLaughlin). Yet, despite some Western consumers reporting such issues having an impact upon their purchasing decisions, social justice has not become a significant issue of concern for most. The popular cookery publications discussed above devote little space to Fair Trade product marketing, much of which is confined to supermarket-produced adverzines promoting the Fair Trade products they stock, and international celebrity chefs have yet to focus attention on this issue. In Australia, discussion of contemporary slavery in the press is sparse, having surfaced in 2000-2001, prompted by UNICEF campaigns against child labour, and in 2007 and 2008 with the visit of a series of high profile anti-slavery campaigners (including Bales) to the region. The public awareness of food produced by forced labour and the troubling issue of human enslavement in general is still far below the level that climate change and ecological issues have achieved thus far in driving foodway evolution. This may change, however, if a ‘Slow’-inflected connection can be made between Western lifestyles and the plight of peoples hidden from our daily existence, but contributing daily to them. Concluding Remarks At this time of accelerating techno-cultural evolution, due in part to the pressures of climate change, it is the creative potential that human conscious awareness brings to bear on these challenges that is most valuable. Today, as in the caves at Lascaux, humanity is evolving new images and narratives to provide rational solutions to emergent challenges. As an example of this, new foodways and ways of thinking about them are beginning to evolve in response to the perceived problems of climate change. The current conscious transformation of food habits by some in the West might be, therefore, in James Lovelock’s terms, a moment of “revolutionary punctuation” (178), whereby rapid cultural adaption is being induced by the growing public awareness of impending crisis. It remains to be seen whether other urgent human problems can be similarly and creatively embraced, and whether this trend can spread to offer global solutions to them.

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.

Therefore, the problem of rational use of natural resources, in particular protection of early spring plant species is very important. However, literary sources analysis only reveals data on the biology of species of this genus. The present research,conducted in the spring of 2017-2019, focuses on anatomical and morphological features of two Altai species: Gagealutea and Gagea minima; these features were studied, clarified and confirmed by drawings and photographs. The anatomical structure of the stem and leaf blade was studied in detail. The obtained research results will prove useful for studies of medicinal raw materials and honey plants. The aforementioned species are similar in morphological features, yet G. minima issmaller in size, and its shoots appear earlier than those of other species Keywords: Flora,gageas,Altai species,vegetative organs., Refference: I.

View | Download INFLUENCE OF SUCCESSION CROPPING ON ECONOMIC EFFICIENCY OF NO-TILL CROP ROTATIONS Authors: Victor K. Dridiger,Roman S. Stukalov,Rasul G. Gadzhiumarov,Anastasiya A. Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

Belyayeva,Fatima S. Datieva,Larisa R. Datieva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00046 Abstract: The aim of this work was to assess the functional reserves of the body to quantify individual health; adaptation, psychophysiological characteristics of the health quality of medical students in different seasons of the year. When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
