Key points in this POSTnote include:

  • Extreme rainfall events are predicted to become more frequent and severe in the future as the climate changes.
  • Existing urban defences and drainage infrastructure cannot cope with increasingly extreme events, but urban areas can be adapted to reduce vulnerabilities to flooding.
  • There is no single solution to manage urban flood risks: a portfolio of solutions will be needed that include traditional flood defences but also flood resilience measures.
  • Urban drainage systems that mimic a natural landscape can reduce surface flooding and provide other benefits.

  • Plastic packaging waste has become a key consumer concern. In the UK, over 2.2 million tonnes of plastic packaging enter the consumer market each year. Much of this is used in the food sector because plastic packaging is cheap, light to transport, hygienic, and can be used to extend the product’s shelf-life. In the UK around 46% of plastic packaging is collected for recycling, mostly through local authority collections. However several issues with the current systems of plastics recycling persist. This POSTbrief reviews proposals to Defra and HM Treasury to improve plastics recycling in the UK .
