Food waste has a negative impact on people around the world, affecting the economy, environment, and society. Recognized as an international problem, much effort has been taken to identify goals and potential measures to reduce waste at every stage of the supply chain, both domestically and globally. This paper presents the results of a survey conducted among young adult residents (aged 18–25) of Poznań, a city with a population of over 500,000, with the aim of identifying the reasons for food waste by consumers, exploring methods to reduce it, and determining the level of public awareness of the issue and its consequences at household-level. The study found that consumers have difficulty purchasing adequate amounts of food and tend to prepare excessively large portions. The results provide valuable information for local governments, municipal authorities, companies, shops, schools, and other institutions that can use it to organize educational and informational campaigns targeted at consumers.
The aim of the study is to analyze environmental changes in the area between Gopło and Szarlejskie Lakes. The Noteć River flows through this area, connecting both lakes. The lakes could have been connected and functioned as Wielkie Gopło. Geological reconnaissance was based on five boreholes drilled with a soil auger. The samples were subjected to granulometric analyses and the content of organic matter and calcium carbonate was determined. Eight samples were radiocarbon-dated using the AMS method. Recognition of the valley bottom settlement was done through spatial analysis using six Archaeological Project Records sheets. The results of the research allowed separating three phases of the area development: lake, bog and lake again. The beginning of the last lake development phase and its evolution have not been precisely dated and require research. Archaeological data demonstrate the poor settlement use of the glacial trough. Throughout the prehistoric period, settlement was concentrated at an altitude of 80–85 m above sea level, in the edge zone of trough. This means that the area was marshy and inaccessible for settlement. Drainage, regulation works in the Noteć river basin and industrial activities, led to the lowering of the groundwater level and weakened the lake’s recharge. Consequently, the lake disappeared from the studied area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
