Despite the widespread adoption of OH, culling remains a key component focuses on pathogen evolution and host–pathogen relationships. . are typically beyond the scope of developing nations (Sims, ). biosecurity or breakdowns in herd immunity would inevitably leave us .. Epub Jul 4.

In political philosophy, and, consequently, public health policy, public goods are understood to be the strict preserve of human interests and human benefits Coggon, ; Rushton, In its broadest and most inclusive explication, however, OH aims to attain optimal health for humans, non-human animals and their shared environments.

Because human, animal and ecological health are explicitly linked, OH approaches could potentially justify privileging non-human interests with the presumptive aim of promoting mutual benefits to both humans and non-human animals Capps and Lederman, ; Rock and Degeling, Yet, much of the current scientific discourse and practice that describes itself as OH specifically focuses on pathogen evolution and host—pathogen relationships. While developing a detailed understanding of how hosts and pathogens change and interact is important, the ecological dimension implicit within a OH approach might require us to acknowledge that infectious pathogens are key constituents of the ecological systems in which humans and animals live together.

In this article we critically review the ethical justifications for culling animals as a measure to control and prevent infectious disease of economic or public health concern.

Using the threats posed by highly pathogenic avian influenza HPAI viruses as a case study, we explore whether and how culling and other current control measures might be justified as part of OH approaches to the risk of animal-borne infectious disease.

Our purpose is to further nascent discussions about the ethical dimensions of OH and to explore the implications arising from OH for public health ethics. In its broadest formulation, the harm principle holds that the only legitimate basis for interfering with an individual's liberties and choices is to prevent non-consensual harm to others.

Under this principle, harms are understood to be actions that are injurious or that set back important interests of rights-holders. Accordingly, animals that carry an infectious risk are subject to interventions to minimize and prevent harm to humans.

The simplicity of this idea is, however, deceiving. In the first instance, any judgment about harm requires a normative evaluation. Therefore a decision must first be made as to the types and magnitudes of harm that are relevant Verweij, For example, is the presence of a mild disease in production animals that poses minimal risk to human interests sufficient to trigger depopulation measures?

Secondly, because harms are seen to be the consequences of actions or omissions, determinations on the presence of harm require a comparison between two or more alternate states.

Therefore, all the relevant potential harms and benefits caused by each of the possible responses available must be weighed against each other, which, in the case of an animal-borne infectious diseases, have been mainly focused on economic evaluations and the protection of the public. Importantly, not all set-backs are harms, and in most legal jurisdictions, rights-holders are exclusively natural people or legal entities.

Domestic animals are typically property, under law, which means their owners have a greater moral claim for determining their value and the right to make most of the decisions about how they will be used. Animal welfare legislation provides some protection to animals in many jurisdictions, but their slaughter is not considered to cause them harm as long as it is conducted humanely.

Conversely, the mandatory killing or culling of animals is understood to cause harms to the important interest of their owners—by restricting their choices as to how their property is used and how the benefits of ownership are realized.

This is why public health-mandated culling programmes often involve some measure of compensation for the legal owners of animals. While liberal approaches such as those promulgated around the harm principle are often held up as being individualistic in opposition to more communitarian ideals Jennings,the idea of community is still central to how the harm principle is operationalized in public health.

Being part of the community that benefits from a public good relies upon the active maintenance of systems, institutions and environments that sustainably maintain and promote benefits for all people.

Establishing and maintaining the good for the benefit of a community becomes more important when populations are conjoined or contiguous within a shared system—such that health is shared communally Coggon, What is the Good of OH? Arguments based on the public good are both prospective and instructive Dawson, They concern the kinds of communities we want to live in; the shared interests and values important to maintaining these collectives; and, thereby, a framework through which we should seek to achieve specific types of community understood as ways of living our lives togetherand distribute any costs and benefits.

Traditional justifications for culling animals rest on balancing the interests of rights holders i. OH approaches—putatively predicated on maintaining and sharing health across species boundaries—invite a reconsideration of who or what should be included as subjects of a shared or common good such that it is framed around a broader set of contributors and beneficiaries.

In other words, the OH approach requires us to understand health as a good we share with other species.

Culling and the Common Good: Re-evaluating Harms and Benefits under the One Health Paradigm

Moving the core concerns of public health beyond consideration of only the needs and interests of human communities to include our shared dependencies and interests with animal populations and ecosystems would go some way towards incorporating OH objectives into standard public health approaches.

They describe universal goods as: Capps and Lederman, Thus any OH approach would run counter to narrow liberalism in which ethical considerations are limited to negotiating conflicts between rights-holders, competing human interests and the maintenance of public goods. Conceptualizing health as a universal good has the potential to promote radical reform.

Because the health of humans, animals and ecosystems is inextricably linked, OH approaches might entail the construction and consideration of a non-human account of interests when policies are drafted and executed. While such a move could potentially drive us into endless cycles of utilitarian calculus and moral debates as to the respective value of different types of subjectivity, in its very foundations OH explicitly invites interdisciplinary and pluralistic approaches.

Drawing on casuistry, the ethical dimensions of OH can be grounded in empirical cases where the focus is on the nature of the dependency, and the distribution of harms and benefits across and between human and non-human populations Light and McKenna, ; Rock and Degeling, Rather than the harm principle, judgments about the appropriateness of different responses to heightened infectious risk can be based on the consequences of individual actions for the good of the collective—assessed through their impacts on human and non-human health, biodiversity and ecosystem resilience.

From this more modest position of accepting that human and non-human interests are both central to the maintenance of a universal good, and of relevance to effective infectious disease control, some key principles to guide OH interventions can be put forward without becoming embroiled in broader debates about the moral importance of animal life and the ethics of animal use.

Below we illustrate some of the tensions that emerge from founding OH around a public good in relation to culling and other measures to control HPAI. We begin to explore what framing approaches to animal-borne infectious diseases around a universal good might imply for the governance and management of infectious risk.

Playing Chicken—Putting Culling in Context There are now more than 7 billion people in the world—three times as many as Meanwhile, global poultry production has increased by a factor of 10, such that hundreds of millions of chickens are slaughtered for food each year FAO, Increases in productivity have been achieved by an expansion of the scale of production and intensification on a per unit basis—both in stocking density and through the selection for desired genetic traits.

Villages in developing countries most often keep their poultry collectively as flocks of up to free-range birds with minimal costs and without any measures for biosecurity. However, poultry production in developing countries in Asia is growing rapidly, and consequently becoming more diverse. Large industrial-style production units now sit alongside small backyard holdings—often in peri-urban areas Thornton, The shift to intensive poultry production occurred earlier in Europe and North America—where demand and the industry have stabilized in the last few decades.

The emergence of H5N1 HPAI strains from Asian poultry flocks in indicates that gains in productivity from intensification have an external cost—beyond animal welfare concerns and the associated costs of heritable diseases. HPAI has attracted global media and public attention because of fear the virus may mutate into a strain capable of human-to-human transmission. Human infections with HPAI are closely linked with outbreaks in domestic poultry.

LPAI viruses are endemic in wild waterfowl where they tend to cause mild respiratory symptoms Peiris and Yen, Adapted to non-aquatic environments, HPAI rarely causes disease in wild bird populations because previous LPAI infection affords some protection against more virulent strains.

HPAI has spread around the world through poultry production and trade systems that have failed to establish or maintain adequate levels of biosecurity. Notably, proposed solutions to the persistence of HPAI in poultry production systems—such as increasing flock size in larger more biosecure installations—are primarily focused on enhancing outbreak detection and improving the time and amount of control within which infection containment and farm disinfection measures can be implemented.

Control strategies for HPAI have relied on four basic components: Note that the first three measures are primarily preventive, the fourth is reactive—infected or at-risk birds are culled in response to an outbreak.

Vaccines developed from LPAI strains were first introduced in as further preventive measures. Yet, even as vaccination against influenza is a mainstay of human health protection, for public health reasons it is not typically used for primary prevention in poultry. Vaccinated birds can still be infected, provide a host for virus mixing and genetic mutation, shed the virus and spread the infection to other susceptible hosts—avian, porcine or human.

Mass poultry vaccination can lead to problems identifying birds that carry the virus but do not have disease, making it difficult to control the spread of the virus to other host, including people. Finally, there are technical barriers to poultry vaccine effectiveness. Because we now live in a globalized world, new influenza viruses can spread across populations and continents in ways that outpace current vaccine-making technologies Peiris and Yen, Consequently, control programmes against HPAI have focused on eradicating the virus from poultry populations through culling.

In responding to HPAI, considerably less emphasis has been placed on evaluating the effectiveness of culling, including their impacts on industry and community Oparinde and Birol, Killing chickens to curb influenza outbreaks has significant costs. Moreover, the economic burden of animal-borne diseases disproportionately affects developing nations.

As well as being dependent on the acceptability of compensations offered to producers, the effectiveness of the mass culling programmes relies upon robust and reliable disease reporting, tracing and surveillance systems—which are typically beyond the scope of developing nations Sims, Consequently, vaccination has sometimes been added to responses to HPAI outbreaks because poultry depopulation has failed to eradicate the disease, or the need to maintain rural livelihoods and food security were a pressing concern Swayne, Since China, Vietnam and Indonesia have attempted to control HPAI by vaccinating all domestic flocks—with immediate positive impacts but limited long-term success.

Outbreaks of HPAI still occur sporadically in many countries in South East Asia because the virus remains endemic to some poultry production systems, and continues to jump into and circulate within wild waterfowl populations. To reduce threats posed by HPAI strains, government agencies and industry are increasing surveillance and creating evermore biosecure production systems that remove points of contact between poultry flocks, wild birds and potential human vectors Hinchliffe and Lavau, Thus, the emergence of LPAI viruses of these two subtypes in poultry has now become the trigger for aggressive pre-emptive culling.

Yet, the threats posed by HPAI outbreaks to human and animal health remain high. HPAI and the Public Good Ethical reasoning can establish principles that bound what sorts of practices are acceptable or unacceptable in specific situations. A deeper engagement with ethics might not only have a profound impact on how animal disease control is executed but also how it is perceived. In as much as the normative dimensions of OH can be framed around the promotion of common or universal goods, moving beyond the preserve of human interests requires us to share the risks, burdens and goods of infectious disease control Rock and Degeling, Interventions that seek to deliberately exclude humans from burdens or explicitly withhold benefit from non-human others, thereby, become ethically problematic.

Because they are currently construed and implemented towards protecting a public good, measures for animal infectious disease control are strictly oriented around avoiding harms to humans and maximizing human benefit. Of the measures currently available to address HPAI, only poultry vaccination and the enhancement of biosecurity across global poultry industries could conceivably confer benefit on non-humans. But for overriding prudential and economic reasons, within the current mixture of production structures neither of these measures is likely to produce the intended outcomes of offering effective control of infectious risk for all over the longer-term.

Enhanced biosecurity systems, properly maintained, could prevent the entry and circulation of influenza viruses in poultry production and thereby provide a shared benefit to human and non-human alike.

Similarly, vaccinating poultry against avian influenza could potentially provide these animals with some protection, while also safeguarding the economic interests and livelihoods of their owners. However, no security system is perfect—and even if we developed a highly effective vaccine against a broad range of avian influenza viruses and could reliably inoculate wild bird populations, it is likely the costs of establishing and then maintaining herd immunity year after year would be prohibitive to maintaining a commercially sustainable poultry industry—and likely continue to leave small-holders and their communities exposed to higher levels of economic and zoonotic risk.

Consequently, unless producers and the society that pays for their products remain committed to bearing the costs, the level of investment required to establish and maintain a influenza-free space for all types of poultry production would mean that any breaches to biosecurity or breakdowns in herd immunity would inevitably leave us in the same situation as our current circumstance—where aggressive and pre-emptive culling is, economically if not ethically, the only available infection-control strategy.

As the case of HPAI illustrates, there are clear practical and political hurdles to simply transitioning OH discourse and practice from public to universal goods.

The broader the groups of entities whose interests are included as subjects of the good, the more complex and contentious calculations about interests, burdens and benefits become. Harms, Competing Interests and More-than-Human Communities One of the key premises of OH is the co-dependency of human, animal and environmental health, thus requiring collective actions to attain shared goals. One way we could begin to establish which shared dependencies are relevant to OH, and which harms to non-human interests conflict with the promotion of a universal good, is to distinguish between congruent, convergent and common interests.

According to Angus Dawson So, for example, human and non-humans both have a common interest in services civic or ecological that help to maintain an environment capable of providing safe and sustainable sources of food and water.

If supported by some form of collective action, common interests can instantiate common goods. From this perspective, common goods are emergent properties of how the community is organized. Drawing on the work of Geoffrey RoseDawson asserts that perturbations in how common interests are expressed—through social attitudes, food production systems or environmental protections—can have substantial population level effects.

This is why the protection of common goods is often sufficient justification for mandating collective actions.

Common interests can be contrasted with congruent and convergent interests. Congruent interests are those that we share with other individuals that essentially run parallel with each other and typically require minimal collective action for their provision.

They are collections of interests in the same kind of thing possessed by a large number of individuals. Thinking across species boundaries, access to sexual mates for the purposes of reproduction are congruent interests we share with other species.

Congruent interests may be important and beneficial to meeting the needs of specific individuals, but are unlikely to be important for OH and the provision of universal goods because they are not based on attaining the exact same goal for the benefit of all Postema, Whereas convergent interests are those most members of a community have in the same thing, but attaining them requires public provision. Convergent interests are broadly understood to aggregate to support public goods in that they require widespread social co-operation to create and maintain them.

Except for possible examples, such as off-leash dog-walking areas in public parks and the stringent regulation of pet food to ensure it is safe for human consumption, as currently construed, convergent interests almost always aggregate into the provision of public goods in ways that exclude the needs of non-humans such as animals, plants and ecosystems. In contrast, common goods implicitly already include non-human interests because they transcend simple aggregations and distributions of benefit in that they are indivisible—we already share common goods with non-humans and, by the their nature, they are goods which cannot be shared out Cribb, Implicitly at least, a OH approaches require us to understand health as a common good we share with other species.

If OH requires us to value and account for non-human interests, then the common goods entailed by promoting flourishing and sustainable multi-species communities and inter-species health protection, could plausibly be described as a universal good. However, articulating OH around meeting common human and non-human interests will still require some of the trade-offs in harms and benefits described previously.

Therefore, the degree to which something like preventing outbreaks of HPAI promotes health as a universal good depends on the extent to which the burdens and benefits are shared across species boundaries. Primary vaccination of all poultry could conceivably promote health as a universal good, but humans will have to bear a larger proportion of the burden of the risks to health posed by HPAI outbreaks.

Re-configuring OH to Address Structural Disadvantage So far we have limited discussion to what OH can achieve within the structure of existing production systems that remain articulated around contaminationist models of infectious disease control. From this it would seem that remaining wedded to the more limited anthropocentric frame of public goods will prescribe policies and practices that are not significantly different from traditional existing public health approaches to animal-borne infectious disease.

Conversely, a more inclusive and locally embedded approach to the provision of universal goods might support policies and practices for economically important endemic animal diseases and zoonotic risks that explicitly seek to co-promote human and non-human benefits. These include approaches that seek to address the risks of HPAI further upstream—by seeking to modify more distal rather than proximal causes of disease emergence. Drought as related to precipitation may be a result of several growing days without precipitation, low seasonal precipitation, or abnormally low annual precipitation for a particular year or even for a period of years.

Weather Bureau defines drought as a period when rainfall is but 30 percent of average for 21 days or longer. Other such definitions state that drought occurs when annual precipitation is 75 percent of normal, or monthly precipitation is 60 percent of normal It is generally understood that drought conditions along with alternate periods of high precipitation appear rather regularly over time throughout the range areas of the world. In a period of 15 to 20 years, range areas would expect a series of high forage producing years and likewise a series of drought years with herbage production far below normal 22, It is acknowledged that many expressions of ecological communities are the result of plant tolerance to environmental extremes such as temperatures wind, and soil moisture.

In most range ecosystems of the world, precipitation is indeed limiting. Most dominant species on arid range lands have developed adaptations to cope with intermittent periods of deficient soil water. Plants of arid rangelands of the world have been classified as: There are many drought resisting plants in grasslands of the world that renew growth following dormancy even though there is no apparent soil water available Some of the xerophytic adaptations of plants are: Some plants are able to control rate of transpiration by control of stomatal aperture and by means of a covering of resins or pubescence.

It is sometimes said that xerophytes are plants that are found only on desert areas; however, current thinking is that xerophytes occur on all arid rangelands. At least it can be said that most plants growing on arid ranges are xerophytic in their tolerance to deficient soil water or atmospheric conditions which promote rapid water loss. Anatomical and physiological adaptations common to xerophytes have evolved under many different degrees and kinds of xeric environments.

On saline desert sites, the plant growth is further impeded because of the difficulty of absorbing moisture against the osmotic pressure of high salt content in the soil. Since extremes in climatic conditions are to be encountered throughout the range areas of the world, the ability of range ecosystem managers to cope with fluctuating climatic and herbage conditions is indeed difficult, because such alternating cycles are not precisely predictable for management purposes.

Research has so far failed to present methods of pre-dieting forage yield from existing or pre-existing soil and climatic factors.

However, with the aid of high speed computers and expert analysis it should not be too long before herbage yield in many areas can be determined with a high degree of accuracy by means of past weather features, climatic patterns, and soil water along with other parameters related to plant growth. This may involve form of precipitation, distribution over certain periods, soil water to varying depths at the beginning of the growing season, atmospheric temperatures, and evapo-transpiration-precipitation ratios.

Some scientists feel that it is better, for managing and using the forage resource, to predict droughts, rather than simply recognizing average herbage dynamics from season to season as a result of current soil and weather conditions. It would, of course, be of inestimable value for the range manager if he could forecast drought incidence and intensity at least a season or even a year in advance. The solution to low herbage yield during drought periods may lie in man's ability to control weather through cloud seeding.

Even though this does not appear promising at the moment, it may someday be developed to the degree that it will at least moderate unfavorable rainfall periods.

Drought and its relationship to dynamics of primary productivity and production of grazing animals

It should be pointed out that extreme drought conditions or droughts of long duration seldom cover more than a particular region of the western U. Therefore, the entire livestock industry of the west never suffers a poor production year, and thus, relief can be received by an interchange of grazing agreements among grazing areas Figure 1.

Drought and vegetation changes The debatable issue that climate alone causes permanent change in the range ecosystem has not been conclusively settled, even though weather records have been available since the early 's However, the effect of climate upon permanent change in vegetation composition, along with other related factors such as livestock grazing, fire and small herbivores, has been immensely confounded.

The frequency and duration of drought are both important in determining the severity of the effect of climate upon botanical composition. It is common knowledge that most plants that inhabit rangelands are subject to stresses of limited precipitation at some time during the annual growth cycle, whether for a period of a few weeks or a few months.

This might be a normal climatic rhythm or it might be somewhat subnormal. In addition to droughty periods that commonly appear sometime during the annual life cycle of a plant, there are drought spells that last several years. Thus, intensity and duration of drought may be identified either within months of the year or among years over time infinitum.

The species composition and dynamics of the primary producers of the range ecosystem are determined largely by the ability of plant species to survive long periods of deficient soil water Studies in mixed prairie in northern central plains during the drought of the period showed profound changes in height growth and species composition, but few dominant species completely died in most plant communities 32, 3.

In some cases, however, a few species were lost in some plant communities. Hurtt 15Lommasson 19and Lang 18 found that even some deep-rooted woody plants died and were almost totally absent after the drought in In a study by Albertson and Tomanek 1 that covered a period from to it was found that the drought of the 30's caused a loss of plant species in the short grass communities to the extent that it was dominated by only one species, and even this species was reduced in quantity by less than a third of normal.

These same authors found that the tall grasses and mixed grasses in the Central Plains states showed marked changes in percent species composition, but the extent of change and reduction in herbage cover was much less than in the short grasses.

This is to be expected, since the tall and mixed grasses had more favorable site conditions. However, on the extreme western portion of the mixed grasses between the short and mixed grasses, the tall grass species were completely eliminated from many valley bottoms as a result of drought and dust.

In the mixed prairie of the Central Great Plains, the drought in which the precipitation was less than one-half of normal for a period of 6 years caused the vegetation even in protected areas to change markedly
