Some prominent Mesoamericanists long considered lowland central Veracruz to have been agriculturally unproductive prior to the Totonacs' construction of a canal-irrigation system at Zempoala during the Middle Postclassic period (A. D. 1200-1400). This evaluation reflects a long-standing negative predisposition toward tropical lowlands and a preoccupation with the significance of canal irrigation in the emergence of urban societies. However, an appreciation of mesoenvironments and their ecological interrelations has led to a reevaluation of agriculture in central Veracruz. In wetlands to the south of Zempoala, evidence of canals and planting platforms supporting maize cultivation by A. D. 500 demonstrates that people were intensively cultivating that mesoenvironment by the Classic period (A. D. 1-850). Moreover, vestiges of sloping-field terraces occur throughout some 1,000 km2 of piedmont west of those wetlands. Direct evidence for crops and a chronology are still lacking for these latter fields, but ethnohistorical data and plant ecology suggest cotton, maize, agave, and a Prehispanic origin.

Recent adjustments to the chronology of the northern Maya Lowlands have brought about a closer alignment of the decline of Terminal Classic/Early Postclassic Yucatecan polities with the collapse of the southern Maya states. The collapse of the entire Classic-period societal structure throughout the lowlands can now be compressed into a 200- or 250-year period and seen as a progressive chain of events that began in the south and culminated with the fall of Chichen Itza in the eleventh century. This new reconstruction has led us to propose eliminating the Early Postclassic period, the existence of which was based largely on a purportedly late occupation of Chichen Itza. We assign this final occupation of the Itza capital to the Terminal Classic period, which ended sometime in the eleventh century in the northern Maya Lowlands.

Early Classic Period

Based on published lexicostatistical dates, two intervals in the prehistory of southern Mesoamerica stand out as fertile periods in terms of the generation of new languages: the Terminal Preclassic/early Early Classic Periods, and the Early Postclassic Period. After comparing archaeological evidence with language distributions within the subregions of southern Mesoamerica during the first of these periods, we conclude that the cultural processes during both periods had the same potential for producing rapid rates of linguistic divergences. Just as rapid proliferation of linguistic divisions was symptomatic of the well-known collapse of Late Classic Maya civilization, so it can be taken as a sign of a collapse of Terminal Preclassic civilization. Both collapses were characterized by severe population reductions, site abandonments, an increasing balkanization in material culture, and disruption of interregional communication networks, conditions that were contributory to the kind of linguistic isolation that allows language divergences. Unlike in the Terminal Classic collapse episode, small refuge zones persisted in the Early Classic Period that served as sources of an evolving classicism; these refuge zones were exceptions, however, not the rule. Although the collapse of each site had its own proximate cause, we suggest that the enormous geographical range covered by these Early Classic Period site failures points to a single ultimate cause affecting the area as a whole, such as the onset of a prolonged and devastating climatic change.

Small Scale Irrigation

Sectoral economic growth data in Ethiopia show that the agriculture sector has the lowest growth, which is caused by frequent drought and inefficient technologies, among other factors. As a result, the productivities of land and labor, as well as the income of small-scale farm households, are very low, and rural areas have a relatively high poverty rate. A quasi-experiment was applied to understand the impact of using small-scale irrigation motor pumps on farmers’ livelihood improvement. Specifically, a survey was conducted in 2019 on a sample of 92 small-scale irrigation motor pump and canal irrigation users as the treatment and control groups. The weighted propensity score matching method was applied to eliminate initial differences and adjust sampling proportions across the groups. Based on the average treatment effect on the treated estimation results, we cannot state that the mean income difference in small-scale irrigation motor pump users and canal irrigation system users is different from zero. This indicates that countries with little capital to invest in large-scale irrigation projects can introduce household-level small-scale irrigation motor pumps to improve farmers’ incomes.

Early Postclassic

In 1931 and 1932, George Vaillant and Sigvald Linné excavated 34 burials and 17 offerings dating to the Early Postclassic period (a.d.900–1150). The features were located on the ruins of the Classic-period site of Teotihuacan and within the boundaries of a roughly 25–50 ha zone identified by the Teotihuacan Mapping Project as having a dense Early Postclassic-period occupation. The results of Vaillant's excavations have not been published. An examination of the Vaillant–Linné data sheds new light on Early Postclassic-period mortuary ritual and social organization. The identification of several types of burials shows that local people conducted primary and secondary mortuary rituals and indicates the presence of at least two social strata at the site. The content of the burials and offerings supports a division of the Early Postclassic period into two local phases, Mazapan (ca.a.d.900–1000) and Atlatongo (ca.a.d.1000–1100/1150), with these features dating to the earlier phase.

AbstractMaya codices were important repositories of cultural knowledge and traditions passed down through the centuries. Rather than being focused on human actors, however, the Late Postclassic period Maya screenfolds contain almanacs that predict the movements of celestial bodies during earlier time periods. The purpose of these seemingly “out-of-date” tools was to predict the future based on notions of cyclical time. Recent research suggests that centuries-old astronomical almanacs do more than model the past or formulate rituals. Instead, they are formulated to integrate celestial events with other cycles of time and to contextualize them with events from the mythic past, such as the destruction of a former world by flood. The memory of this calamitous primordial event, framed in terms of astronomical and seasonal cycles, is preserved in pre-Hispanic and historic documents as a means of conveying the ill-fortune associated with like-in-kind events that are certain to repeat, and of scheduling the performance of appropriate ritual actions to mitigate their destructive potential.
