In areas where waste management is inadequate, the welfare of free-roaming animals can be significantly affected by the ingestion of plastic waste, potentially impacting human livelihoods and health. However, the effect of plastic pollution on terrestrial animals is poorly understood. Using a combination of methodologies from animal behaviour, environmental and social sciences, this study assesses the effects of plastic pollution on donkeys, cattle and their owners in Kenya. Behavioural observations suggested that donkeys and cattle preferentially fed at waste sites, where 1 in every 10–20 items ingested were plastic. Faecal sampling also showed much higher concentrations of microplastics than those reported in previous studies of farmed cattle and significantly higher concentrations in the faeces of donkeys and cattle grazing at waste sites compared to rural areas. Survey data showed that the majority of livestock owners believed that plastic pollution was a problem, and nearly a third of local residents had witnessed an animal becoming ill following plastic ingestion, reporting mortality rates of 78%. Triangulating data from multiple methods highlights the risks terrestrial plastic pollution poses to domestic animals, demonstrating the need for interdisciplinary projects that tackle this important issue by addressing the interconnectedness of human behaviour, animal welfare and environmental health.

Shifts from direct implementation to advocacy-based programming have been documented across many non-governmental organisation (NGO) sectors, including animal welfare. Semi-structured interviews with 32 staff from different positions within animal welfare NGOs explored recent programming changes. Maintaining a balance between direct implementation and advocacy-based activities emerged as a strong theme. The findings suggest that risks are associated with both the direct implementation status quo and transitioning to an advocacy-based focus. Risks of the former include treating symptoms rather than root causes of welfare problems. Organisational change can be disruptive and necessitates realignment of core competences, in turn influencing NGO mission. Identified risks of transition include loss of individuals whose values fail to align with new programming directions, increased upwards accountability requirements for accessing institutional donors and difficulties when phasing out direct implementation approaches. Whilst having to be dynamic, NGOs need to evaluate the risks associated with programming decisions, considering their vision, mission and staff identity in order to ensure that welfare programming is as effective as possible.

An understanding of the factors influencing the human-animal relationship is relevant in the development of welfare interventions for working equids. However, the link between the psychological attributes of animal owners, such as empathy level and pain perception, and the welfare state of working horses is yet to be studied. Here, we assessed working horse owners’ empathy, their perception of equine pain and how these relate to the welfare state of their horses. The relationship between empathy and perception of equine pain was also explored. One hundred owners of working horses were studied, along with their working horses (n = 127). Self-reported rating scales were used for measuring animal-oriented empathy, human-oriented empathy and owners’ perception of equine pain; higher scores in the three scales indicated higher levels of empathy and higher perception of equine pain. An animal welfare index based on direct measures was applied where higher scores indicate a poorer welfare state. Most of the owners had high levels of empathy towards both animals and humans and a high perception of equine pain. According to the animal welfare index, 15.7% of horses had a poor welfare state. Higher levels of empathy and equine pain perception in owners were correlated with a better animal welfare condition, with owner's empathy level towards animals explaining over 60% of horses’ welfare. Moreover, empathy towards animals was positively correlated with human-oriented empathy and perception of equine pain. We therefore suggest that strategies oriented to improve welfare of working horses should consider education programmes aimed at promoting the development of empathy in caretakers.
