Ignoring flood risks leads to increasing losses: assessment should include climate change, land use and economic development

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.

Citizens recycle even in the absence of economic incentives, shows study from Malta

Recycling has significant environmental benefits and is key to a circular economy. The EU has set a goal for Member States to recycle 50% of their municipal waste by 2020 and plans to set a 65% target for 2030, although progress towards this goal is variable. This study assessed a waste separation scheme in Malta, a Member State with traditionally low levels of recycling. Even though mixed waste was collected more frequently and for free, residents contributed to the voluntary recycling scheme, with participation increasing over time. This study provides useful insights for developing voluntary policy approaches.

Biodegradable plastics: testing can help inform most appropriate end-of-life options, but also reveals environmental concerns

Scientists have tested the behaviour of biodegradable plastics in managed composting and anaerobic conditions, as well as under simulated environmental conditions, such as in seawater or soil. This study found that blending different types of biodegradable plastics may open up new opportunities in relation to their end-of-life treatment — notably the potential to make one of the world’s best-selling biodegradable plastics, polyactic acid (PLA), home-compostable by blending it with another polymer (polycaprolactone — PCL). However, the researchers were also concerned that most materials tested could still cause plastic pollution as they failed to biodegrade sufficiently — and, in some cases, not at all, in particular, in soil and the marine environment.
