This paper provides an overview of food waste in the context of food security, resources management and environment health. It compares approaches taken by various governments, community groups, civil societies and private sector organisations to reduce food waste in the developed and developing countries. What constitutes ‘food waste’ is not as simple as it may appear due to diverse food waste measurement protocols and different data documentation methods used worldwide. There is a need to improve food waste data collection methods and implementation of effective strategies, policies and actions to reduce food waste. Global initiatives are urgently needed to: enhance awareness of the value of food; encourage countries to develop policies that motivate community and businesses to reduce food waste; encourage and provide assistance to needy countries for improving markets, transport and storage infrastructure to minimise food waste across the value chain; and, develop incentives that encourage businesses to donate food. In some countries, particularly in Europe, initiatives on food waste management have started to gain momentum. Food waste is a global problem and it needs urgent attention and integrated actions of stakeholders across the food value chain to develop global solutions for the present and future generations.

This paper draws on nine years of undergraduate student course evaluation surveys to explore learning and teaching practices in an introductory public policy course in Australia. The paper situates student responses in terms of an increasingly complex teaching and learning environment. The student cohort includes a diverse group of arts, law, business and technology-based undergraduates. The paper explores both quantitative and qualitative survey data in order to draw out students’ perceptions and views on teaching, learning and their engagement with public policy. The paper considers some of the ways students grapple with increasing levels of complexity, their perceptions of interactive and participatory teaching strategies as tools for learning, and their views around enhancing university learning. The paper provides a set of reflections that may enhance student experiences in increasingly complex environments.
