Evidence centre

What we know and what is missing

Literature, data and field reports answer different questions. Provenance and review depth are shown before conclusions are compared.

01 / Evidence types

Three complementary libraries

02 / Editorial synthesis

Report, map and open questions

These syntheses link sources and make coverage limits explicit.
