Drought, agricultural adaptation, and sociopolitical collapse in the Maya Lowlands
Paleoclimate records indicate a series of severe droughts was associated with societal collapse of the Classic Maya during the Terminal Classic period (∼800–950 C.E.). Evidence for drought largely derives from the drier, less populated northern Maya Lowlands but does not explain more pronounced and earlier societal disruption in the relatively humid southern Maya Lowlands. Here we apply hydrogen and carbon isotope compositions of plant wax lipids in two lake sediment cores to assess changes in water availability and land use in both the northern and southern Maya lowlands. We show that relatively more intense drying occurred in the southern lowlands than in the northern lowlands during the Terminal Classic period, consistent with earlier and more persistent societal decline in the south. Our results also indicate a period of substantial drying in the southern Maya Lowlands from ∼200 C.E. to 500 C.E., during the Terminal Preclassic and Early Classic periods. Plant wax carbon isotope records indicate a decline in C_4 plants in both lake catchments during the Early Classic period, interpreted to reflect a shift from extensive agriculture to intensive, water-conservative maize cultivation that was motivated by a drying climate. Our results imply that agricultural adaptations developed in response to earlier droughts were initially successful, but failed under the more severe droughts of the Terminal Classic period

Mesoamerican urbanism revisited: Environmental change, adaptation, resilience, persistence, and collapse
Urban adaptation to climate change is a global challenge requiring a broad response that can be informed by how urban societies in the past responded to environmental shocks. Yet, interdisciplinary efforts to leverage insights from the urban past have been stymied by disciplinary silos and entrenched misconceptions regarding the nature and diversity of premodern human settlements and institutions, especially in the case of prehispanic Mesoamerica. Long recognized as a distinct cultural region, prehispanic Mesoamerica was the setting for one of the world’s original urbanization episodes despite the impediments to communication and resource extraction due to the lack of beasts of burden and wheeled transport, and the limited and relatively late use of metal implements. Our knowledge of prehispanic urbanism in Mesoamerica has been significantly enhanced over the past two decades due to significant advances in excavating, analyzing, and contextualizing archaeological materials. We now understand that Mesoamerican urbanism was as much a story about resilience and adaptation to environmental change as it was about collapse. Here we call for a dialogue among Mesoamerican urban archaeologists, sustainability scientists, and researchers interested in urban adaptation to climate change through a synthetic perspective on the organizational diversity of urbanism. Such a dialogue, seeking insights into what facilitates and hinders urban adaptation to environmental change, can be animated by shifting the long-held emphasis on failure and collapse to a more empirically grounded account of resilience and the factors that fostered adaptation and sustainability

La Corona: un acercamiento a las polÃticas del reino Kaan desde un centro secundario del noroeste del Petén
The La Corona Regional Archaeological Project is studying the northwestern Peten region (Guatemala), where the ancient Maya city of La Corona is located. This site has been recently identified as the unknown Site Q. The research at La Corona has included excavations of monumental and settlement architecture, mapping, use of remote sensing and ecological and paleo-climate studies. Viewed from the political organization models, investigations at La Corona present an opportunity to study the nature and political relations of secondary sites. Epigraphic data show a direct affiliation between La Corona and the ruling dynasty of Calakmul, suggesting that La Corona could have been a key center for the expansionistic strategies of Calakmul during the sixth and seventh centuries A.D. In this paper we present some of the results obtained in the investigations carried out between 2005 and 2009.El Proyecto Regional Arqueológico La Corona estudia la región del noroeste de Petén, Guatemala, donde se localiza la antigua ciudad maya de La Corona, que recientemente fue identificada como el Sitio Q. La investigación ha incluido las excavaciones de arquitectura monumental, asentamientos, la elaboración de mapas, el uso de sensores remotos y la realización de estudios paleoclimatológicos y ecológicos. Desde el punto de vista de los modelos de la organización polÃtica, las investigaciones en La Corona presentan una oportunidad para estudiar la naturaleza y las relaciones polÃticas de los sitios secundarios. Los datos epigráficos relatan una afiliación directa entre La Corona y la dinastÃa gobernante en Calakmul, por lo que el primer centro seguramente fungió como punto clave para las estrategias de expansión de Calakmul por las Tierras Bajas Mayas durante los siglos VI y VII d.C. Aquà se presentan algunos resultados obtenidos en las investigaciones llevadas al cabo entre 2005 y 2009

Impacts of Climate Change on the Collapse of Lowland Maya Civilization
Paleoclimatologists have discovered abundant evidence that droughts coincided with collapse of the Lowland Classic Maya civilization, and some argue that climate change contributed to societal disintegration. Many archaeologists, however, maintain that drought cannot explain the timing or complex nature of societal changes at the end of the Classic Period, between the eighth and eleventh centuries CE. This review presents a compilation of climate proxy data indicating that droughts in the ninth to eleventh century were the most severe and frequent in Maya prehistory. Comparison with recent archaeological evidence, however, indicates an earlier beginning for complex economic and political processes that led to the disintegration of states in the southern region of the Maya lowlands that precedes major droughts. Nonetheless, drought clearly contributed to the unusual severity of the Classic Maya collapse, and helped to inhibit the type of recovery seen in earlier periods of Maya prehistory. In the drier northern Maya Lowlands, a later political collapse at ca. 1000 CE appears to be related to ongoing extreme drought. Future interdisciplinary research should use more refined climatological and archaeological data to examine the relationship between climate and social processes throughout the entirety of Maya prehistory
