What is umwelt and what does it mean for the industries that use animals?
UMWELT Definition & Meaning | Umwelt definition: the environmental factors, collectively, that are capable of affecting the behaviour of an animal or individual.

We all know that there are things that animals need to survive, food, water shelter, things like that. Wild animals will find these things for themselves, finding or catching their food, preparing it if necessary. A monkey will crack nuts open with rocks, cats remove feathers from birds before eating them. Then there are the things that animals like and don't like. Some animals thrive in company, groups, herds, broods, packs, shoals, clowders. Others prefer to be alone, but for those that want company but not get it and those that don't want company only to have it forced upon them, the result is mental anguish. We all know how humans experience the world and how the world around us affects us, but do we know how different animals experience the world? And, of their experience, do we know how that makes them feel? This is where umwelt comes in.
What Is Umwlet?
The term umwelt, originates from the German language and refers to the "self-world" or the subjective universe unique to each organism. The term was coined by the Baltic German biologist Jakob von Uexküll in the early 20th century and the concept underscores the notion that every living being experiences the world in a way that is distinct to its sensory and perceptual capacities.
The Origins of Umwelt
Jakob von Uexküll, often regarded as a pioneer in the field of biosemiotics, introduced the concept of umwelt in his 1909 book, Umwelt und Innenwelt der Tiere (Environment and Inner World of Animals). Uexküll's work laid the foundation for understanding that an animal's perception of the world is shaped by its sensory and cognitive apparatus. Unlike the human tendency to interpret the world through a predominantly visual and linguistic lens, other creatures might rely more on olfactory, auditory, or tactile stimuli. Often picking up on stimuli that humans cannot perceive.
Uexküll’s revolutionary idea was that every organism's umwelt is a subjective bubble in which it interacts with its environment in ways that are meaningful and relevant to its survival and reproduction. For instance, a tick, which is blind and deaf, relies on the smell of butyric acid emanating from the sweat of mammals to locate its host. To the tick, this smell is breakfast, lunch and dinner, a literal meal ticket. This sharply contrasts with the human umwelt, which integrates a vastly different set of sensory data to navigate the world and does not include finding the smell of butyric acid appetising.
The Meaning of Umwelt
Umwelt emphasises that no two species share the same experiential world. This subjective reality means that animals are not just simpler or less capable versions of humans; they are unique entities with their own modes of experiencing reality. Understanding an animal's umwelt requires us to step outside our anthropocentric viewpoint and appreciate the diverse ways in which life manifests on Earth.
For example, consider a dog. Its umwelt is rich with scents and sounds that humans might be entirely oblivious to. While humans primarily depend on sight to interpret their surroundings, dogs engage with a world where smell and hearing dominate. This distinction profoundly affects how dogs perceive space, identify individuals, and experience their environment.
Implications for Human Treatment of Animals
The concept of umwelt has significant ethical and practical implications for how humans treat animals, especially in controlled environments like zoos. Traditional zoos often design enclosures and exhibits from a human-centric perspective, focusing on visual appeal and convenience for visitors, because visitors mean money. However, if we consider the umwelt of the animals housed within these spaces, it becomes evident that many such environments may fail to meet their sensory and psychological needs.
Enclosure Design: Understanding umwelt suggests that zoos should prioritise environments that cater to the natural behaviours and sensory preferences of their inhabitants. For instance, nocturnal animals might benefit from enclosures that provide ample dark, quiet spaces, while animals with advanced olfactory senses, like bears, need stimuli that engage their sense of smell.
Animal Enrichment: Recognising the distinct umwelt of each species underscores the importance of enrichment activities that align with their natural behaviours. Enrichment for a primate might involve complex puzzles and social interactions, whereas for a reptile, it might include basking spots and hiding places that mimic their natural habitat.
Ethical Considerations: The ethical implications of umwelt challenge us to reconsider the very practice of keeping animals in captivity. If an animal's umwelt is drastically altered or diminished in captivity, it raises questions about the morality of such confinement. The stress and behavioural problems observed in many zoo animals can often be traced back to the inability of their captive environments to replicate the complexity and stimulation of their natural umwelt.
What About Animal Agricuture?
In animal agriculture, applying the concept of umwelt necessitates designing farming practices that align with the natural behaviours and sensory experiences of the animals. This means creating environments that cater to their specific needs, such as providing adequate space for movement, social interactions, and activities that reflect their instinctual behaviours. For example, ensuring that pigs have opportunities to root and forage, or that chickens can engage in pecking and dust-bathing, can significantly enhance their well-being. By acknowledging and accommodating the distinct umwelten of farm animals, agriculture can become more humane and ethically sound.
In reality, animal agriculture often falls short of accommodating the distinct umwelten of farm animals, primarily due to the industrial-scale focus on efficiency and productivity. Many animals are confined in restrictive environments that severely limit their natural behaviours, leading to physical and psychological distress. Practices like intensive confinement, lack of environmental enrichment, and insufficient social interactions starkly contrast with the principles of umwelt, highlighting a significant gap between ethical ideals and current agricultural practices. This discrepancy underscores the need for reforms that prioritize the well-being of animals in accordance with their natural sensory and behavioural needs.
