Welfare biology

Welfare biology is a proposed research field devoted to studying the wellbeing of animals in general, and focused especially on animals in their natural ecosystems. The field of welfare biology would inform measures aimed at helping animals and environmental management policies, and provide this cause with the attention and recognition it needs.

 

What is welfare biology?

Welfare biology can be defined as the study of sentient animals and their environment with respect to wellbeing.1 It represents a distinct approach to the study of the lives of animals in their ecosystems. By incorporating knowledge from animal welfare science, ecology, zoology, and other well established academic fields, this new research area has the potential to improve our understanding of the wellbeing of animals living in the wild and to increase our chances of developing effective strategies to help them.

It is important to bear in mind that welfare biology would not focus on questions for which animals are considered as units or exemplars of other objects of research, as happens with the study of ecosystemic relations and biodiversity. Rather, welfare biology would be focused on animals as sentient individuals, and on what could be good or bad for them. This is what makes this field of research novel, and also what explains its applied potential in terms of animals’ wellbeing.

Some people might not consider the creation of this new field of research important, if they share an idyllic view of the lives of animals in nature. This view is not correct. Wild animals suffer in many ways, including hunger and thirst, injuries, disease, stress, extreme weather conditions, natural disasters, and antagonistic relationships with other organisms. In addition, many animals die very young, and it’s probable that in many cases the pain of their deaths outweighs the positive experiences accumulated during their short lives (see Population dynamics and animal suffering).2 Animals living in the wild can be harmed just as domesticated animals can be, so there is no good reason to disregard animals in the wild.3

We must bear in mind that even if animal advocates concerned with the situation of animals in the wild carry out research about it, such research will never be able to be as deep or comprehensive as what scientists in research institutions and academic departments can do. Moreover, it will not be as influential or likely to trigger further research by other academics. In addition, when it comes to social recognition and to informing policymaking, independent research seldom has the impact that established academic research can.

 

Departing from previous work concerning animals and their environment

Thus far this issue has not been assessed in significant depth in the academic arena. The reasons for this are diverse. We have just seen that, at least for part of the general public, lack of concern for this issue is probably based on the (unfortunately wrong) belief that animals have very pleasant lives in their natural environments and the idea that animals in the wild do not need our help. The main reason this issue has not been considered pressing by life scientists is likely because the focus of their work has been on furthering human interests. Still, as we will see next, the work they have done thus far may provide valid starting points for welfare biology.

Several decades ago, the science of animal welfare was created out of a concern by the general public regarding the terrible ways in which many animals are harmed when they are used for human purposes. While many findings in this field have been employed only to learn how to best exploit the animals studied, much of the research has allowed us to learn about animals’ sentience and how animals can be positively and negatively affected. But little work has been carried out concerning animals in the wild. Researchers on wild animal welfare science have focused on studying the wellbeing of captive animals (such as animals in zoos, wildlife parks and rehabilitation centers),4 animals living in urban and agricultural areas,5 animals affected by hunting and the animal trade,6 and other animals who are directly affected by human activities.7 They have put their emphasis on animals living in close relationships with humans and animal welfare issues caused by human action, overlooking the great majority of wild animals and all the natural harms they suffer. Nevertheless, the methods and the knowledge animal welfare scientists have gathered to date may be applied to assessing how animals in the wild can cope, or fail to cope, with the different situations they find themselves in.

As for researchers in ecology and related disciplines, while they have developed various research fields relevant to gaining a better understanding of wild animal suffering (such as population, community, behavioral, evolutionary, landscape ecology, conservation biology, ethology, wildlife management), there’s still very little information about it. Ecologists have shown interest in animal behavior, life histories, population dynamics, and evolutionary patterns (among other ecological aspects) but have failed to establish the connection that their findings have to the wellbeing of individual animals. However, some of the knowledge already gained in those fields can tell us a great deal about the likely state of wellbeing of animals in their natural environments.

 

Prospects for welfare biology

Despite the lack of attention to this issue, different courses of action benefiting animals living in the wild have been carried out, including the rescue of trapped animals, helping orphans, and giving medical assistance to injured or sick animals (see Helping animals in the wild). Some efforts have affected large numbers of individuals. These include, for instance, programs aimed at feeding populations of mammals and birds with the purpose of favoring endangered, hunted or charismatic species, reducing human-wildlife conflicts, answering ecological questions, or helping animals.8

Also, many wild animals have been saved by vaccination programs from suffering from painful and often lethal diseases such as rabies,9 tuberculosis,10 myxomatosis,11 and swine fever.12 While these measures are typically carried out to stop wild animals from transmitting diseases to domesticated animals and humans, this shows that aiding wild animals is something feasible, and can also provide benefits for humans and other animals. These efforts have been based on studies in different disciplines, which don’t explicitly address animals’ wellbeing. This might explain why their impacts on the lives of individual animals’ wellbeing are not highlighted when these programs are researched and their results are presented.

It may be thought that this issue is not easy to deal with, as current knowledge and technology to improve the welfare of animals in the wild is still insufficient. But this is because there have been no serious attempts to make progress on this issue. As mentioned above, thus far, ecologists and other life scientists have shown little concern for the wellbeing of animals and, instead, have focused their efforts on other issues such as the conservation of biodiversity and other natural resources for human benefit. Establishing research on welfare biology and promoting it may thus increase our ability to successfully tackle it.

The creation of new scientific disciplines that earn respect in academia typically takes some time and the involvement of committed people, but we can find a number of recent examples. Several new fields of research appeared in the 20th century that were not considered as relevant areas of study before and have become respected disciplines in academia. In the case of welfare biology, there are some promising perspectives for the future as more people become concerned about the suffering of animals in the wild. This is happening both among the general public and among people working in academia, especially students and young researchers.

New research projects focused on appraising the wellbeing of animals in the wild and considering the best ways to improve their situation can be designed and accomplished by addressing several different topics. Examples include further research into vaccination programs, as we saw above, work on urban welfare biology for the sake of animals living in urban, suburban, or industrial areas, research on the impact of hostile weather conditions and shelter building for animals’ wellbeing, assessment of parasites, population dynamics and the feasibility of deparasiting efforts, and many others. The importance of these projects being successfully developed is not only that they will be useful to implementing measures and policies to help animals, but also that successful projects can help to raise more interest in carrying out further research on the topic. This can potentially increase the amount of work and publications in this area of research until it becomes established as a new discipline.

Rough estimates suggest that the global population of wild vertebrates may be up to 1014, and that of arthropods maybe up to 1018, and other invertebrates that might be sentient are even more numerous.
