The Harvesting Memories Project: Historical ecology and landscape changes of the Sicani Mountains in Sicily

The Harvesting Memories project aims to investigate the historical landscape dynamics in an inner area of the Sicani Mountains district in Western Sicily (Contrada Castro, Corleone-Palermo). The interdisciplinary approach of the project allowed us to combine and integrate methods from different disciplines such as historical ecology, landscape archaeology, archaeobotany and GIS-based spatial analysis. In this paper some results have been summarized. The comparison between land mosaic change during the last 60 years, the relationship between site catchment area and land suitability and the correlation between archaeobotanical and phytosociological data. This approach underlined the relevance of the historical ecology for understanding landscape trajectories and planning strategy of suitable development of rural areas

Sources of geomaterials in the Sicani Mountains during the Early Middle Ages: A case study of Contrada Castro, central western Sicily

From 2017, an unknown rural settlement in Contrada Castro at Corleone (Palermo Province, western Sicily) was investigated as part of the ‘Harvesting Memories Project’. The stratigraphic sequence, supported by radiocarbon dating, has demonstrated a reoccupation of a pre-Roman site during the transition between the Byzantine and Islamic periods. In particular, the main occupation occurred in the late 8th–9th century when pottery kilns and a probable warehouse were constructed. During the 10th–11th century, a new structure with different orientations replaced the previous buildings that had already collapsed. Specifically focusing on a perspective of the household production and its relationship to the surrounding landscapes of this site, this paper presents the results of a geological survey and petrographic analysis of ceramic finds and lithic samples to identify the source area of the geomaterials used in the studied settlement. The ceramic finds were divided into different Paste Groups based on the characteristics of a polarizing microscope study. The use of some locally available raw materials was recorded both for ceramic and lithic samples. Such an approach enables us to better understand ceramic craft technology, clay and lithic procurement strategies and, more broadly, the consumption of household pottery in the Early Medieval site in Contrada Castro. Furthermore, this study verifies the close relationship that this rural settlement had with the surrounding resources in the area and reveals a connection with the city of Palermo during the Early Middle Ages

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Diminishing benefits of urban living for children and adolescents’ growth and development

Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified

Archeologia nel territorio dei Monti Sicani (Harvesting Memories project). L’insediamento di lunga durata di Contrada Castro (Corleone, Palermo). Prima campagna di scavo 2017.

The “Harvesting Memories” project aims to address diachronic change in landscape and settlement patterns during the long-term in the area of Sicani Mountains in Central-West Sicily (Italy). This area is a sort of palimpsest of Mediterranean inland areas characterized by a long-term occupation of low-lying lands suitable for agriculture and hills for pastoral activi-ties. The settlement dynamics of this inner area are well documented in the archaeological sequence of the hilltop site of Contrada Castro. Recent excavation (spring 2017) showed dry-stone structures related to the Islamic and Norman period (9th-12th c. AD), a Byzantine infant burial (7th-8th c. AD) and evidence (layer of morphology regularization and pottery) con-nected to an archaic indigenous settlement (6th-5th c. BC). The investigation of this new rural site provided relevant insights of longue durée patterns in hilltop settlements of Sicily between Antiquity and Middle Ages

Un nuovo insediamento rurale nel territorio dei Monti Sicani tra epoca bizantina e normanna: dati preliminari sul sito di lunga durata di Contrada Castro (Corleone, PA)

Negli ultimi anni (2015-2017) sono state avviate delle ricerche archeologiche sulle dinamiche diacroniche dei paesaggi di una porzione di territorio localizzata a sud del comune di Corleone corrispondente alle contrade Castro e Giardinello delimitate a nord dal massiccio promontorio di Pizzo Castro o Rocche di Mezzogiorno e ad est dalle pendici del Monte Barraù. Il progetto Harvesting Memories ha previsto diverse fasi di studio relative alle traiettorie ecologiche e alle trasformazioni del paesaggio (Università di Palermo) e indagini archeologiche (Soprintendenza BB. CC. AA. di Palermo). In questo contributo si presentano i risultati preliminari di una prima campagna di scavo (marzo-maggio 2017) in Contrada Castro (Corleone, Palermo), uno dei siti identificati dalle indagini di superfici

The Sicilian Countryside in the Early Middle Ages: Human–Environment Interactions at Contrada Castro

Within the project ‘Harvesting Memories: Ecology and Archaeology of Monti Sicani Landscapes’, this paper aims to reconstruct human–environment interactions in the inland areas of Western Sicily during the Early Middle Ages through a comparative analysis of environmental archaeological data. We analyse carpological and anthracological finds and faunal remains originating from different layers of the rural settlement of Contrada Castro (Corleone, Palermo), excavated in 2017–2019. The site was mainly occupied between the Byzantine and Islamic periods (late 8th to 11th c. AD). The examination of wood charcoal enabled the identification of plant species selected and exploited in the landscape of the site for each main chronological period. The archaeobotanical data indicated a precise, qualitative picture on the historical vegetation of this area, accompanied with the agricultural practices of the communities. The zooarchaeological data added further information on the reconstruction of rural economy and animal exploitation patterns. An integrated comparison of the characteristic landscape and the archaeobotanical and zooarchaeological data presented the dynamics of agricultural strategy, wood exploitation, and management of animal resources of an early medieval rural community in Western Sicily

The settlement of contrada castro (Corleone, Palermo) between the Byzantine and Islamic Periods (7th-11th c. AD)

Since 2015, a fruitful collaboration between a private bio-farm, Bona Furtuna LLC, the University of Palermo and the ‘Soprintendenza BB.CC.AA.’ has been established within the ‘Harvesting Memories’ project, which is focused on the study of long-term landscape transformations as a result of the diachronic interaction between human socio-economic patterns and environmental and ecological trends. The investigation of the site of Contrada Castro reveals new insights into the settlement dynamics before and after the first stage of the Aghlabid conquest of western Sicily, a real ‘dark age’ from the perspective of archaeological knowledge, especially in a rural area. The material culture, archaeozoological and archaeobotanical data have also indicated the high potential of the site for the reconstruction of economic and human-environment interaction trends of an early medieval community during the complex transition from the Byzantine to Islamic period
