Measuring and being measured are some of the fundamental aspects of our worlds. Without them, we cannot live in our environments or function as social beings.

It is creative. h is introduction to the special issue explores how these themes of measurement are played out in diverse settings, including counting i sh stocks, migration, social resilience, local measures of sustainability, oil exploitation, forest conservation, calculating ecosystem services, and measuring heat.
