keskkonnaohu

Keskkonnaohu is a term used to describe a potential threat to the environment that can arise from human activities, natural processes, or their combination. It denotes situations in which ecological systems, biodiversity, or ecosystem services may be harmed, degraded, or disrupted if the hazard materializes. The word combines keskkond (environment) and ohu (danger or threat), reflecting a focus on environmental risk rather than actual damage.

Keskkonnaohu covers a broad range of phenomena. It includes chemical pollutants and nutrient run-off that affect air, water, and soil; biological threats such as invasive species or pathogens; physical disturbances like noise, radiation, or excavation impacts; and changes driven by climate events or land-use alterations. Natural hazards, such as floods or landslides, can become keskkonnaohu when they threaten ecosystems or threaten service provision, even though they occur without human intent.

Assessment and management of keskkonnaohu typically involve hazard identification, exposure assessment, vulnerability analysis, and risk characterization. Monitoring, precautionary planning, and risk reduction measures are used to prevent or mitigate effects. Environmental impact assessments, ongoing surveillance, and emergency preparedness are common tools in handling keskkonnaohu, often guided by national and EU environmental frameworks. Agencies such as a country's environment ministry or environment agency may coordinate studies, reporting, and response efforts to protect ecosystems and maintain ecological integrity.

Examples of keskkonnaohu include polluted water bodies, habitat fragmentation, soil contamination, invasive species, and climate-related risks that threaten biodiversity and ecosystem services. Understanding and addressing keskkonnaohu supports informed decision-making in land use, industry, and conservation.
