Urban sustainability indicators are tools that allow city planners, city managers and policymakers to gauge the socio-economic and environmental impact of, for example, current urban designs, infrastructures, policies, waste disposal systems, pollution and access to services by citizens. They...

Mercury (chemical symbol Hg) is a heavy metal occurring on earth in various forms. It can be converted from one form to another by natural processes, and, once released, actively cycles in the environment for hundreds to thousands of years before being buried in sediment. It is well known for...

The growing human population and a shift to more resource-intensive habits and behaviours are increasing the demands on global ecosystems. Natural capital is a way to describe Earth's natural assets, including soil, air, water, and living things, existing as complex ecosystems, which provide a...

One of the greatest challenges facing today's environmental policymakers is how to deal with complex risks, such as those associated with climate change. These risks are difficult to deal with because they are not precisely calculable in advance. Where there is scientific uncertainty about the...

The majority of persistent organic pollutants (POPs) identified until now are banned or restricted around the world owing to concerns about their harm to ecosystems and human health. However, this is not the end of the story; even long-banned POPs still linger in the environment; others are...

Environmental protection and human food security co-exist in a critical balance, one that is often difficult to get right. The pressures of population rise, farming intensification, and loss of habitats and species mean that protections afforded under the EU's Common Agricultural Policy are...
