The fluviokarst Rio Bravo watershed of Belize Central America is about 400 km2. More importantly, it has global implications for the long-term human alteration of a tropical forest. We have studied this watershed’s geomorphology and archaeology since 1995. We have documented many ancient Maya modifications like terraces, wetland canals and fields, and reservoirs. We have recently been able to quantify canals and wetland field complexes. We have found four main agricultural zones that date back as early as 2000 BP but came to fruition from 1300 to 1000 BP, at the end of Maya Classic and the beginnings of the Post Classic. These canal complexes extended the known area of wetlands and altered river and karst geomorphology in this watershed.
