The ethics and politics of the caged layer hen debate in New Zealand

Changes in attitudes toward animal welfare, with a greater emphasis on the importance of allowing animals to express normal patterns of behavior has led to an examination of the practice of keeping hens in battery cages. There is widespread scientific consensus that the conditions of confinement and the barren nature of battery cages severely restrict hens’ behavioral repertoire, and are thus detrimental to their welfare. The New Zealand Animal Welfare Act 1999, stipulates that animals must have “the opportunity to display normal patterns of behaviour.” In spite of this provision, the New Zealand government has not acted in phasing out battery cages, arguing instead that there is insufficient evidence that welfare will be improved by a phase-out. There is evidence of strong industry pressure on the government, and the use of tactics common in policy considerations where changes are resisted by powerful interests. It is important that policy processes are better managed so that welfare changes are based on both public preferences and scientific knowledge, and ways of doing this are discussed.     

Science, Pigs, and Politics: A New Zealand Perspective on the Phase-Out of Sow Stalls

Sows housed in stalls are kept insuch extreme confinement that they are unableto turn around. In some sectors of the porkindustry, sows are subjected to this degree ofconfinement for almost their entire lives(apart from the brief periods associated withmating). While individual confinement isrecognized by farmers and animal welfarecommunity organizations alike, as a valuabletool in sow husbandry (to mitigate againstaggression), what remains questionable from ananimal welfare point of view is the necessityto confine sows in such small spaces.In 2001, the Australian Journal ofAgricultural Research published a reviewarticle on the science associated with the useof the sow stall, and claimed that ``noscientific evidence to support therecommendation in the Code of Practice advisingagainst housing of sows in stalls followed byhousing in crates' (Barnett et al., 2001, p. 21).If all the available scientific publications onthe animal welfare implications of sow stallsare consulted (many of which did not feature inthe above review), then one will indeed findscientific evidence to support recommendationsagainst the housing of sows in stalls. Becausethere is science on both sides of this policydivide, the argument to defend the use of sowstalls, therefore, is not one of science vspublic opinion, but one of ethics.An analysis of the scientific argumentsagainst the use of the sow stall should be usedto encourage ethical debate on this issue. Asan ethical debate, the issue of the use of thesow stall can then focus on the degree ofsuffering we as a society are willing totolerate in agricultural practices, and theanimal welfare costs associated with extremeeconomies of scale in sow stocking rates,rather than get bogged down in red herringdebates over whether there is any suffering atall.     

Sustainability in the USA and New Zealand: explaining and addressing the implementation gap in local government

This paper describes the frustrating reality of sustainability implementation in the USA and New Zealand (NZ), an early adopter of sustainability mandates. Local government has a key role in implementation, but has been slow to uptake sustainable practices. We surveyed senior planners in small to medium-sized local government agencies in both countries to identify which features of local government support (or hinder) sustainability in practice.

Environmentally sustainable practices are not well entrenched in either country. In the USA, the framing of sustainability and public support are significant predictors of implementation. However, sustainability is rarely a priority. In NZ, local government capacity is the main driver of implementation. We recommend that planners promote sustainability values, reconcile economic development goals with sustainability (e.g., green economy model), and translate public support for sustainability into institutional priorities. NZ localities also need increased capacity and US localities need continued Federal and State support.     

Environmental whole farm management plans: their character, diversity, and use as agri-environmental indicators in New Zealand

This paper reports on a nationwide survey of environmental farm plan programmes and plan characteristics, towards determining New Zealand's (NZ's) capability and eligibility for reporting on the Organisation for Economic Cooperation and Development's (OECD) environmental whole farm management plan agri-environmental indicator. Considerations regarding the validity of the indicator are discussed. Environmental farm planning in NZ is widespread, fragmented, and diverse. Nine of NZ's 16 regional authorities have environmental farm plan programmes involving 20 different types of environmental farm plans. Potentially half of NZ's total area of farmland is included, but this is reduced by limited and selective use of environmental farm plans as policy instruments. Three authorities are capable of readily reporting the number and coverage of their environmental farm plans; six would need to manually compile the information. Compliance monitoring is mostly informal, but necessary for checking the implementation of plan works and actions. Eligibility of NZ environmental farm plans cannot be determined until the OECD define acceptance standards. A contemporary definition of environmental farm plans is proposed, along with additional criteria necessary to ensure such plans are credible indicators of issue ownership, adoption of best management practice, and landscape changes intended to improve environmental quality.     

The Ethics and Politics of Animal Welfare in New Zealand: Broiler Chicken Production as a Case Study

The cause of poor welfare in broilers is multifactorial, but genotype is a major contributor. Modern broilers have been bred for rapid growth, and this leads to increases in lameness and ascites as the legs and hearts of the heavier birds find it difficult to cope with the extra demands placed on them. Visible lameness indicative of pain is more common in New Zealand than in Europe. The government, however, insists that New Zealand welfare standards are higher than Europe. The government also appears to have a strong antipathy to those demanding better welfare for broilers. Reasons for this antipathy and disparities between government statements and research results are discussed. Government publications reveal that animal welfare is seen as a question of image for market access and that there is little concern with animal welfare as an ethical imperative for its own sake. The Animal Welfare Act in theory makes it an offence to ill treat an animal, but in practice allows exemptions for industrial agriculture. The interests of animals may be better protected by an independent animal welfare advisory service.     

Minimizing Harm in Possum Control Operations and Experiments in New Zealand

Pest control operations andexperimentation on sentient animals such as thebrushtail possum can cause unnecessary andavoidable suffering in the animal subjects.Minimizing animal suffering is an animalwelfare goal and can be used as a guide in thedesign and execution of animal experimentationand pest control operations.The public has little sympathy for the possum,which can cause widespread environmentaldamage, but does believe that control should beas painless as possible. Trapping and poisoningprovide only short-term solutions to the possumproblem and often involve methods that causesuffering. Intrusive experiments connected withthese methods of control and published in thelast 6 years are reviewed. Many of theexperiments do not attain the welfare standardsrequired by members of the public.Possums also act as vectors for bovinetuberculosis. While this is not as important inthe minds of the public as environmentaldegradation, as long as people wish to continueraising cattle, this disease needs to becontrolled.Immunocontraception is a humane means ofcontrolling possums with wide publicacceptance. The use of vaccines for cows and/orpossums would also cause far less sufferingthan present eradication operations. Researchinto these methods does require some intrusiveexperimentation. This can be reduced if liveanimals are not used for secondary antibodyharvesting, if adequate analgesia is provided,and if potential vaccines or contraceptives aretested under conditions that would beexperienced in the field.     

Access rights for outdoor recreation in New Zealand: some lessons for open country in England and Wales

Access opportunities for outdoor recreation in New Zealand and England and Wales are classified according to their conformity with collective, citizenship or exclusion rights and their degrees of permanence. Alternative criteria for the apportionment of access rights are considered in the context of this classification. Different criteria for rights apportionment are found to be appropriate according to different circumstances in the context of pluralist provision. Policy developments in New Zealand are compared with those in England. After 150 years of a dominance of collective rights in New Zealand current policy is shifting provision towards exclusionary rights. In England, there is a policy shift in the other direction, towards collective rights. Lessons for the development of collective rights in England are drawn from the New Zealand experience in relation to styles of governance, public preferences, public cost, insurance liability and the potential of markets.     

Spatial Modeling and Habitat Quantification for Two Diadromous Fish in New Zealand Streams: A GIS-Based Approach with Application for Conservation Management

We developed logistic regression models from data on biotic and abiotic variables for 172 sites on Banks Peninsula, New Zealand, to predict the probability of occurrence of two diadromous fish, banded kokopu (Galaxias fasciatus) and koaro (G. brevipinnis). Banded kokopu occurrence was positively associated with small streams and low-intensity land uses (e.g., sheep grazing or forested), whereas intensive land uses (e.g., mixed sheep and cattle farming) and lack of riparian forest cover impacted negatively on occurrence at sampled sites. Also, if forests were positioned predominantly in lowland areas, banded kokopu occurrence declined with increasing distance to stream mouth. Koaro occurrence was positively influenced by catchment forest cover, high stream altitudes, and areas of no farming activity or mixed land uses. Intensive land uses, distance to stream mouth, and presence of banded kokopu negatively influenced koaro occupancy of stream reaches. Banded kokopu and koaro presence was predicted in 86.0% and 83.7% agreement, respectively, with field observations. We used the models to quantify the amount of stream reaches that would be of good, moderate, and poor quality, based on the probability of occurrences of the fish being greater than 0.75, between 0.75 and 0.5, or less than 0.5, respectively. Hindcasting using historical data on vegetation cover undertaken for one catchment, Pigeon Bay, showed they would have occupied most of the waterway before anthropogenic modification. We also modeled potential future scenarios to project potential fish distribution.
