Inter-observer reliability in transect-based observations of environmental waste in greater accra and kisumu: implications for waste management.

Unlabelled: Transect surveys are widely used to quantify mismanaged plastic waste discarded to the environment. However, very few studies have quantified inter-observer reliability in environmental waste surveys. The aim of this study was to assess inter-observer reliability for a set of environmental waste indicators derived from transect surveys in slum areas of two sub-Saharan African cities.
