Abstract
Cities depend on their surrounding bio-physical landscape, utilising goods and services provided to urban populations from ecosystems. These include provisioning services such as food and water; regulating services such as climate and flood control; supporting services such as nutrient cycling and crop pollination; and cultural services such as connecting urban inhabitants to natural values. The health of the ecological system within and surrounding the city influences the health of the city itself. UN Environment recognises that building the resilience of urban populations depends on how climate and non-climate drivers are tackled together. The management of urban and surrounding peri-urban ecosystems has the potential to contribute significantly to the overall resilience of the city to climate change and other pressures.
