Conny Waters – AncientPages.com – Between 750 and 900 CE, the Maya lowlands in Central America underwent a big demographic and political decline. Scientific research have lengthy linked this collapse to repeated episodes of intense drought throughout that interval. For a few years, the prevailing concept was that the local weather disaster performed a central function within the downfall of the Maya civilization.

Nonetheless, latest evaluation of sediment samples relationship again 3,300 years presents new insights that partially problem this established view. Benjamin Gwinneth, a geography professor at Université de Montréal and an skilled on environmental change affecting Maya civilization, has carried out in depth analysis on the Itzan website in present-day Guatemala.
What Occurred?
By analyzing core samples from sediments collected at Laguna Itzan—a lake close to the archaeological website—Gwinneth and his crew are reconstructing each human exercise and weather conditions over time. Their work helps to construct a extra nuanced understanding of how environmental components could have influenced historic occasions within the area.
No proof of drought has been discovered within the area. Nonetheless, the Maya inhabitants declined concurrently with areas in Guatemala and Mexico that did expertise drought situations.
So what occurred?
Gwinneth and his crew analyzed three key geochemical indicators within the Itzan lakebed sediment to realize insights into previous environmental and human exercise. Polycyclic fragrant hydrocarbons had been measured to evaluate the depth of slash-and-burn fires, whereas leaf waxes supplied details about vegetation sorts and precipitation patterns. Moreover, fecal stanols served as a proxy for estimating inhabitants density.
By analyzing these indicators collectively, the researchers had been capable of reconstruct adjustments in inhabitants dimension, agricultural practices, and local weather from the earliest proof of human presence round Laguna Itzan 4,000 years in the past up till its abandonment roughly 1,000 years in the past.
“The info revealed that the primary everlasting settlements appeared 3,200 years in the past,” mentioned Gwinneth in a press launch. “There have been slash-and-burn fires and a rise in inhabitants. In the course of the Preclassic interval, between 3,500 and a couple of,000 years in the past, the Maya used hearth extensively. They practiced slash-and-burn agriculture, utilizing hearth to clear the forest after which rising crops on the fertile ashes.”
New Farming Practices
A radical change occurred through the Basic interval, between 1,600 and 1,000 years in the past: though populations had been a lot denser, the usage of hearth decreased significantly. “This in all probability signifies that many of the land had been cleared, which may have led to a change in agricultural technique,” mentioned Gwinneth.
The info counsel a significant intensification of agriculture, together with ridge and furrow ploughing to scale back erosion and intensive gardening. “Fireplace was not an essential part of their farming practices,” Gwinneth mentioned. “This transformation displays gradual urbanization and means that the Maya had been altering agricultural methods to feed a rising inhabitants.”
This alteration in agricultural practices is in step with what archaeologists and anthropologists know concerning the Maya civilization at its peak: it was a fancy, urbanized society with rising specialization and superior agricultural strategies tailored to the surroundings.
The Steady Local weather Riddle
Nonetheless, evaluation of hydrogen isotopes has proven that, not like Maya websites additional north that suffered drought, Itzan appears to have had a secure local weather on account of its geography.
“Itzan is situated close to the Cordillera, the place atmospheric currents from the Caribbean generate common orographic (mountain-related) rainfall,” Gwinneth defined. “Whereas different Maya areas suffered devastating droughts, Itzan appeared to have a secure local weather.”
Gwinneth considers this discovery important as a result of some archaeologists have argued that the Maya collapse started within the southwestern area, the place Itzan is situated. If Itzan didn’t expertise drought, this will’t have been the preliminary reason for the decline, he mentioned.
“Despite the fact that there have been no drought situations domestically, the inhabitants of Itzan declined sharply through the Terminal Basic interval, between 1,140 and 1,000 years in the past,” Gwinneth continued. “Inhabitants markers present a dramatic fall, indicators of agriculture disappear, the location was deserted.”
How can we clarify {that a} group with water and beneficial situations suffered the identical destiny as its neighbours, who had been by drought?
Deadly Interdependence
“The reply lies within the interconnectedness of Maya societies,” mentioned Gwinneth. “The cities didn’t exist in isolation; they fashioned a fancy community of buying and selling relationships, political alliances, and financial dependence.
“When the central lowlands had been hit by drought, this will likely have triggered a cascading sequence of crises: wars between cities over assets, the collapse of royal dynasties, mass migrations, disruption of commerce routes, and so forth.”

Based on this concept, Itzan’s decline was not on account of a scarcity of water, however fairly to its entanglement within the upheaval that adopted the collapse of the broader system it belonged to. The interconnectedness of Maya cities meant {that a} drought in a single space may set off widespread disruption. Even when drought situations had been localized, their results rippled outward, resulting in a domino impact that contributed to the collapse of cities all through the area.
“The transformation or “collapse” of the Maya civilization was not a mechanical results of a uniform local weather disaster; it was a fancy phenomenon wherein local weather, social group, financial networks and political dynamics had been intertwined,” Gwinneth concluded.

“Regional socio-political and financial components performed a decisive function.”
Gwinneth considers these findings important for our present period, as they provide worthwhile insights into how civilizations adapt to environmental adjustments. This attitude may also help us higher perceive the challenges we face at present and inform our responses to ongoing environmental shifts.
