In Madagascar, you could follow and work on environmental arcaeology!

In UK, University College of London

There are lots of countries and universities working on it.There are also Master's just based on this research subject:

Umea University

UCL

Sheffield...

Indeed, just in Spain there are lots of research groups working on enviromental archaeology in some extent. For example, the team I'm working with, the Research Group in Mediterranean Social Archaeoecology ASOME (Autonomous University of Barcelona), has some specialists in geoarchaeology, archaeobotany, zooarchaeology, etc.

Florida Museum of Natural History, University of Florida, Environmental Archaeology Program.

Depends on how tied you are to a program called "Environmental Archaeology." Traditionally the subject matter included in EA was included in geoarchaeology, a discipline that includes archaeology, geology, paleoecology and other forms of archaeological sciences. Many of the more established programs will be under this name. If you are looking for a school though, you should first look for journal articles that interest you and see where the authors either teach or received a degree. It is possible that the program may be in "paleoecology" but an advisor you respect specializes in environmental archaeology. Plus this will give you more information about a potential advisor that you can use when you contact them for the first time (obviously you should do this before applying).

Outside of this approach, the answers you get will be biased by someone else's research interests and some confusion about what environmental archaeology includes. In my opinion, many of the schools in the southwestern United States (Texas, New Mexico and Arizona) have great geoarchaeology programs, but I am more interested in surficial geology and soils geomorphology in site formation processes...and I also work in desert landscapes (my bias).

In Brazil, Museu Nacional was a pioneer in Archaeobotany!

In England, the country has excellent rules supporting cultural resource management. York University is one place to study

I also endorse The University of Sheffield.

There is Université Laval, in Québec city, Canada. Pr Allison Bain is specialized in environmental archaeology and archaeoentomology.

Best regards.

Currently one of the best Environmental Archaeology Program is at The University of Texas at San Antonio. http://anthropology.utsa.edu/

Boston University.

University of Sheffield was a great answer. Unfortunately, the archaeology department at Sheffield is being closed, as reported by Umberto Albarella on 13 July 2021.

Unfortunately, the archaeology in Sheffield will be closed.
