Humaninduced

Humaninduced is a term used to describe processes, events, or conditions that are caused or substantially influenced by human activity. It is most often written as human-induced or, in formal scientific writing, as anthropogenic. The closed form humaninduced is uncommon but may appear in some texts, particularly when compound terms are concatenated.

In climate science, human-induced climate change refers to warming and related impacts driven by greenhouse gas emissions, deforestation, and other anthropogenic factors. In geology, human-induced or induced seismicity denotes earthquakes triggered by activities such as wastewater injection, mining, or reservoir filling. In ecology and land-use planning, human-induced habitat loss, degradation, and fragmentation arise from urban expansion, agriculture, and infrastructure development, often altering species distributions and ecosystem services. In public health, human-induced environmental and social changes can influence disease emergence and spread. In biotechnology, human-induced pluripotent stem cells describe cells reprogrammed from adult tissues to a pluripotent state for research and therapeutic purposes (commonly referred to as hiPSCs).

Usage notes: while the concept is widely recognized, the hyphenated form human-induced and the single word anthropogenic are more common in formal writing. The closed form humaninduced tends to appear in older texts or in certain style guides. The term emphasizes causation by humans rather than natural processes and is used across disciplines to distinguish anthropogenic effects from natural phenomena.
