Human Ecosystem
Human Ecosystem
The concept of a human ecosystem refers to human-dominated ecosystems that are characteristic of the Anthropocene era. These ecosystems are complex, cybernetic systems viewed through conceptual models that integrate various factors such as economics, sociopolitical organization, psychological influences, and physical environmental conditions. They are studied by ecological anthropologists and other scholars to understand the ecological aspects of human communities.
Structure of a Human Ecosystem
Human Environed Unit
A central component of a human ecosystem is the human environed unit, which can be an individual or a group of individuals. This unit interacts with its environment, driving the dynamics within the ecosystem. These interactions and transactions are crucial to understanding the ecosystem's function and sustainability.
Environment
The environment in a human ecosystem is divided into three interrelated components:
-
Natural Environment: This includes all biotic and abiotic factors from the natural world. For example, temperature, pH levels, and other physical conditions vary across different parts of the human body, such as the skin and the gastrointestinal tract.
-
Human Constructed Environment: This refers to all man-made structures and modifications to the natural environment. Urban areas, for instance, represent human-constructed environments where human activity has significantly altered the natural landscape.
-
Human Behavioral Environment: The aspects involving human actions, cultural practices, and social interactions. This includes the psychological and sociopolitical dimensions of human life, which influence and are influenced by other environmental factors.
Interactions and Transactions
The interactions within a human ecosystem are complex and multifaceted. They involve various transactions between the human-environed unit and the environment, such as the exchange of goods, services, and information. These interactions are essential for the sustainability and resilience of the ecosystem.
Total Human Ecosystem
The concept of the Total Human Ecosystem (THE) was proposed by ecologists Zeev Naveh and Arthur S. Lieberman in 1994. It is an ecocentric model that broadens the understanding of human ecosystems by emphasizing the integration of all environmental factors. THE underscores the necessity to consider both biotic and abiotic components and their interplay with human activities.
Ecosystem Services
Human ecosystems provide various ecosystem services, which are the benefits humans derive from ecosystems. These include provisioning services like food and water, regulating services such as climate regulation, cultural services offering recreational and spiritual benefits, and supporting services necessary for other ecosystem services, like nutrient cycling and soil formation.

Understanding human ecosystems is vital for developing sustainable practices that balance human needs with ecological health and integrity. By examining these complex systems, societies can better address environmental challenges and promote a harmonious coexistence between humans and their environments.
