Article
Full-text available
The land use of the ancient Maya strongly affected the environment of the previously forested Maya Lowlands. A forest grew back after the Maya “collapse”, some 1100 years ago. Two activities of the ancient Maya could have had widespread effects on the tree species composition of the regrown, modern forest. First, in areas with topographic relief Ma...
Article
Population pressure and migration are often central features of many hypotheses related to ancient Maya population declines, abandonment episodes, settlement, and sociopolitical organization. The Rio Bravo Conservation and Management Area (RBCMA) in northwest Belize shows archaeological evidence for several depopulation and resettlement events. Wor...

The northwest region of Belize, known as the Rio Bravo Conservation and Management Area (RBCMA), is a research set-aside of interest for investigating hinterland communities of the prehistoric Maya. The hinterland or rural communities of the RBCMA are as diverse and complex as any across the Maya lowlands. The Programme for Belize Archaeological Pr...
Article
Investigations concerning the earliest Maya have been of archaeological interest for many decades. Northern Belize serves as a valuable region for researching and understanding early Maya developments. In particular, the ancient Maya site of Colha in northern Belize is a focal point of some early developments beginning in the Archaic period. Select...
Article
Wetlands epitomize all forms of the proposed Anthropocene era because they record both past and recent human environmental interaction and because of their abundant resources. This is especially true for tropical wetlands, and a growing body of research demonstrates their important connections with past and Indigenous societies. Maya culture, for e...
Article
Full-text available
Understanding civilizations of the past and how they emerge and eventually falter is a primary research focus of archaeological investigations because these provocative data sets offer critical insights into long-term human behavior patterns, especially in regard to land use practices and sustainable environmental interactions. The ancient Maya ser...
Article
Full-text available
Significance Understanding agricultural subsistence is vital for understanding past complex societies. Lidar data are indicating widespread ancient Maya infrastructure. Wetland agriculture was crucial to ancient cultures, but no previous study coupled lidar with multiproxy evidence to demonstrate the extent and uses of Maya wetland fields. We condu...
Article
We compare the geomorphology and soil of two ancient Maya wetland agricultural complexes in modern day Belize. This paper focuses on 3,000 years of soil geomorphology and paleoecological change to determine the chronology of wetland formation and human use in this region. We also characterize Maya manipulation of the environment over time, especial...
Chapter
The prehistoric Maya site of Colha and a Terminal Classic event at the site (human decapitation) serve as a case study for significant social-political changes. The nature of the violent and dramatic event suggests changes that were quite intentional for removing the form of political organization that previously failed the society of Colha. Variou...

Significance The rise of complex societies and sustainable land use associated with urban centers has been a major focus for anthropologists, geographers, and ecologists. Here we present a quantitative assessment of the agricultural, agroforestry, and water management strategies of the inhabitants of the prominent ancient Maya city of Tikal, and ho...
Article
Archaeologists have begun to understand that many of the challenges facing our technologically sophisticated, resource dependent, urban systems were also destabilizing factors in ancient complex societies. The focus of IHOPE-Maya is to identify how humans living in the tropical Maya Lowlands in present-day Central America responded to and impacted...
Article
The ancient eastern Maya Lowlands are characterized by both small, highly resilient communities and the growth of large regional centers. The smaller communities, separated by 2–5 kilometers and dispersed across the landscape, established a circle of interdependency between one another and a spatial separation from the largest centers. Degrees of s...
Article
Full-text available
The access to water and the engineered landscapes accommodating its collection and allocation are pivotal issues for assessing sustainability. Recent mapping, sediment coring, and formal excavation at Tikal, Guatemala, have markedly expanded our understanding of ancient Maya water and land use. Among the landscape and engineering feats identified a...

In 1997, the Chan Chich Archaeological Project excavated a Terminal Preclassic/Early Classic period Maya tomb at Chan Chich, Belize. Tomb 2 represents the earliest royal tomb in the Three Rivers Region of the east-central Yucatan Peninsula and has striking similarities to Burial 85 at Tikal, the tomb of the dynastic founder Yax Ehb' Xook. This pape...
Article
Full-text available
Harkening back to the debates associated with "dualistic economies" in addressing emerging nation states, we examine aspects of the ancient economy of the lowland Maya. Resource-specialized communities were knit together in a network of interdependencies that allowed high degrees of self-sustaining separation from the large monumental centers about...
Article
Prehistoric potbelly (boulder) sculpture has been of great interest for many decades. Most such sculptures occur in the highlands and piedmont of the Pacific Coast in Guatemala and El Salvador. The specific function and dating of the monuments has been of particular concern to researchers. This paper presents a summary of data in an attempt to plac...

Studies of landscape (e.g., Brady and Ashmore 1999; Stanton and Freidel 2005) and social organization (e.g., Fowler and Hageman 2004; Gillespie 2000b; Joyce 2000; McAnany 1995) have recently become prominent in Maya archaeology. Thomas (2001) has suggested that the former is an embodiment of the latter, in that landscape can be considered the resul...

Evidence from preceramic Paleoindian and Archaic time periods in Belize has been recorded over the past quarter of a century by a number of projects. This paper summarizes previously published information and presents new archaeological data in bringing the hunting-and-gathering and itinerant horticultural millennia of this region into a more accur...
Article
The concepts of disaster, vulnerability and societal vulnerability as well as natural threats that are relevant to the Maya area are discussed. Ancient Maya societies were vulnerable to natural threats, such as droughts, diseases and volcanic eruptions. Some of the factors that may be considered as having influenced Maya vulnerability are discussed...
Article
Full-text available
A simple demographic model is developed here that fits the observed data of population loss and recovery following a disaster. The model includes a constant annual growth factor and an immigration wave that is superimposed on it. The constant annual growth factor (∼0.3%) is modified by introducing the concept of Relative Attractiveness of the place...
Article
Because the values of most of the parameters controlling the occurrence and severity of a drought in a given location are unknown, and no periodicity has been observed, droughts can be considered random events. Running a random number generator within the limits of the annual rainfall variability relevant to the Maya lowlands, and defining a “Lean...

The Maya archaeological site at Colha in northern Belize, Central America, has yielded several spouted ceramic vessels that contain residues from the preparation of food and beverages. Here we analyse dry residue samples by using high-performance liquid chromatography coupled to atmospheric-pressure chemical-ionization mass spectrometry, and show t...
Article
Spouted vessels are diagnostic forms of Middle Preclassic (1000-400 B.C.) and Late Preclassic (400 B.C.-A.D. 250) Maya ceramic assemblages. Mayanists have traditionally called these vessels "chocolate pots," but until recently there has been little direct evidence to support this interpretation. In fact, few studies have focused on the role these s...
