Impact refers to the significant or lasting effect or influence that an event, action, or phenomenon has on people, communities, environments, systems, or situations. It encompasses both positive and negative outcomes and can be immediate or develop over time. In various contexts such as social, economic, environmental, or technological spheres, impact is assessed to understand the extent of change brought about by specific interventions or occurrences. Measuring impact often involves evaluating changes in behavior, conditions, knowledge, attitudes, or well-being among affected entities. Understanding impact is crucial for decision-making processes as it helps stakeholders identify successful strategies and areas needing improvement to achieve desired goals and sustainable development.
