Using studies on contemporary Maya farming techniques and important new archaeological research, the authors show that the ancient Maya were able to support, sustainably, a vast population by farming the forest—thus refuting the common notion that Maya civilization devolved due to overpopulation and famine.
Human land use legacies have significant and long lasting impacts across landscapes. However, investigating the impacts of ancient land use legacies ([greater than]400 years) remains problematic due to the difficulty in detecting ancient land uses, especially those beneath dense canopies. The city of Caracol, one of the most important Maya archaeological sites in Belize, was abandoned after the collapse of the Maya civilization (ca. A.D. 900), leaving behind numerous structures, causeways, and agricultural terraces that persist beneath the dense tropical forest of western Belize. LiDAR (Light Detection and Ranging) technology enables detection of below canopy Maya archaeological features, providing an ideal opportunity to study the effects of ancient land use legacies on contemporary tropical forest composition. LiDAR also provided us with a detailed record of the 3-dimensional forest structure over the 200 km2 study area. This allowed the investigation how ancient land uses continue to impact both forest composition, in terms of tree species, and forest structure. I recorded tree species over four land use categories: 1) structures, 2) causeways, 3) terraced, and 4) non-terraced land. Using non-metric multidimensional scaling (NMS) and multi-response permutation procedures (MRPP) to test for differences between the classes, I found significantly distinct tree communities associated with the presence of terraces and the underlying topography. Terraced slopes appear to function as micro-valleys on the side of a hill, creating an environmental "bridge" between slope and valley tree communities. Tree species composition over causeways and structures was also found to be significantly different from terraced and non-terraced plots. Forest structure was assessed by extracting LiDAR points for terraced (n=150) and non-terraced (n=150) 0.25 ha plots. I calculated average canopy height, canopy closure, and vertical diversity from the height bins of the LiDAR points, using slope, elevation, and aspect as covariates. Using PerMANOVA I determined that forest structure over terraces was significantly different from non-terraced land. Terraces appear to mediate the effect of slope, resulting in less structural variation between slope and non-sloped land. These results led to the conclusion that human land uses abandoned [greater than]1000 years ago continue to impact the contemporary forests.
In The Great Maya Droughts in Cultural Context, contributors reject the popularized link between societal collapse and drought in Maya civilization, arguing that a series of periodic “collapses,” including the infamous Terminal Classic collapse (AD 750–1050), were not caused solely by climate change–related droughts but by a combination of other social, political, and environmental factors. New and senior scholars of archaeology and environmental science explore the timing and intensity of droughts and provide a nuanced understanding of socio-ecological dynamics, with specific reference to what makes communities resilient or vulnerable when faced with environmental change.Contributors recognize the existence of four droughts that correlate with periods of demographic and political decline and identify a variety of concurrent political and social issues. They argue that these primary underlying factors were exacerbated by drought conditions and ultimately led to societal transitions that were by no means uniform across various sites and subregions. They also deconstruct the concept of “collapse” itself—although the line of Maya kings ended with the Terminal Classic collapse, the Maya people and their civilization survived. The Great Maya Droughts in Cultural Context offers new insights into the complicated series of events that impacted the decline of Maya civilization. This significant contribution to our increasingly comprehensive understanding of ancient Maya culture will be of interest to students and scholars of archaeology, anthropology, geography, and environmental studies.
The Neotropical area is a main setting of the earliest experiences of domestication ofplants, and evolutionary processes guided by humans, which continue being active inthe area. Studies comprised in this Research Topic show a general panorama aboutsimilarities and particularities of processes of domestication for different plant groupsand regions, some of them illustrate how the domestication processes originated anddiffused, how landscape domestication has operated and continues being practicedand others discuss some of the main challenges for designing policies for biosafetyand conservation of plant genetic resources. It is an attempt to identify main topicsfor research on evolution under domestication, and opportunities that researcherscan find in the Neotropics to understand how and why these processes occurredin the past and present.
An environmental historian delves into the history, science, and philosophy of a paradoxical pursuit: the century-old quest to design natural places and create wild species. Environmental restoration is a global pursuit and a major political concern. Governments, nonprofits, private corporations, and other institutions spend billions of dollars each year to remove invasive species, build wetlands, and reintroduce species driven from their habitats. But restoration has not always been so intensively practiced. It began as the pastime of a few wildflower enthusiasts and the first practitioners of the new scientific discipline of ecology. Restoration has been a touchstone of US environmentalism since the beginning of the twentieth century. Diverging from popular ideas about preservation, which romanticized nature as an Eden to be left untouched by human hands, and conservation, the managed use of natural resources, restoration emerged as a “third way.” Restorationists grappled with the deepest puzzles of human care for life on earth: How to intervene in nature for nature’s own sake? What are the natural baselines that humans should aim to restore? Is it possible to design nature without destroying wildness? Laura J. Martin shows how, over time, amateur and professional ecologists, interest groups, and government agencies coalesced around a mode of environmental management that sought to respect the world-making, and even the decision-making, of other species. At the same time, restoration science reshaped material environments in ways that powerfully influenced what we understand the wild to be. In Wild by Design, restoration’s past provides vital knowledge for climate change policy. But Martin also offers something more—a meditation on what it means to be wild and a call for ecological restoration that is socially just.
For the ancient Maya, food was both sustenance and a tool for building a complex society. This collection, the first to focus exclusively on the social uses of food in Classic Maya culture, deploys a variety of theoretical approaches to examine the meaning of food beyond diet—ritual offerings and restrictions, medicinal preparations, and the role of nostalgia around food, among other topics. For instance, how did Maya feasts build community while also reinforcing social hierarchy? What psychoactive substances were the elite Maya drinking in their caves, and why? Which dogs were good for eating, and which breeds became companions? Why did even some non-elite Maya enjoy cacao, but rarely meat? Why was meat more available for urban Maya than for those closer to hunting grounds on the fringes of cities? How did the molcajete become a vital tool and symbol in Maya gastronomy? These chapters, written by some of the leading scholars in the field, showcase a variety of approaches and present new evidence from faunal remains, hieroglyphic texts, chemical analyses, and art. Thoughtful and revealing, Her Cup for Sweet Cacao unlocks a more comprehensive understanding of how food was instrumental to the development of ancient Maya culture.
Using case studies from around the globe—including Mesoamerica, North and South America, Africa, China, and the Greco-Roman world—and across multiple time periods, the authors in this volume make the case that abundance provides an essential explanatory perspective on ancient peoples’ choices and activities. Economists frequently focus on scarcity as a driving principle in the development of social and economic hierarchies, yet focusing on plenitude enables the understanding of a range of cohesive behaviors that were equally important for the development of social complexity. Our earliest human ancestors were highly mobile hunter-gatherers who sought out places that provided ample food, water, and raw materials. Over time, humans accumulated and displayed an increasing quantity and variety of goods. In households, shrines, tombs, caches, and dumps, archaeologists have discovered large masses of materials that were deliberately gathered, curated, distributed, and discarded by ancient peoples. The volume’s authors draw upon new economic theories to consider the social, ideological, and political implications of human engagement with abundant quantities of resources and physical objects and consider how individual and household engagements with material culture were conditioned by the quest for abundance. Abundance shows that the human propensity for mass consumption is not just the result of modern production capacities but fulfills a longstanding focus on plenitude as both the assurance of well-being and a buffer against uncertainty. This book will be of great interest to scholars and students in economics, anthropology, and cultural studies.
