Penanganan penyakit diabetes menjadi penting karena komplikasi yang dapat terjadi jika tidak ditanggulangi dengan benar. Klasifikasi merupakan salah satu metode yang dapat digunakan untuk mengidentifikasi diabetes. Algoritma klasifikasi ini dapat menganalisis data pasien, seperti usia, jenis kelamin, riwayat kesehatan, dan hasil tes, untuk memprediksi apakah pasien tersebut menderita diabetes. Random Forest dan Naïve Bayes merupakan dua algoritma klasifikasi yang populer. Random Forest adalah metode kompleks yang didasarkan pada penggabungan beberapa pohon keputusan untuk mendapatkan prediksi yang lebih akurat, sedangkan Naïve Bayes merupakan metode pengklasifikasian berdasarkan probabilitas sederhana dan dirancang agar dapat dimanfaatkan denegan asumsi antar variabel penjelas saling bebas (independen). Hasil penelitian menggunakan data sebanyak 70% sebagai data pelatihan dan 30% sebagai data pengujian dari keseluruhan 768 data. keseluruhan yang diperoleh bahwa metode random forest dapat memprediksi penyakit diabetes dengan tingkat persentase sebesar 94% dan tingkat persentase naïve bayes sebesar 78%. Berdasarkan hasil penelitian yang diperoleh metode random forest memiliki tingkat persentase lebih tinggi dibandingkan metode naïve bayes dengan tingkat persentase 94% sedangkan naïve bayes dengan tingkat persentase 78% sehingga dapat disimpulkan bahwa metode random forest merupakan metode terbaik dalam mengindentifikasi penyakit diabetes dibandingkan metode naïve bayes.

Ogei (20): una possible marca de lÃƒÂ¨xica de capacitat ibÃƒÂ¨rica expressada en Ãƒ mfores sobre un dolium de Ruscino (PerpinyÃƒ )
Authors: FERRER I JANÃƒâ€° JOAN
Published: February 2025

The Ruscino dolium, from the 1988 excavations, presents the ogei inscription post cocturam. Even though it comes from a layer without a specific chronology, it could date from the 3rd century or early 2nd century. Its importance in deciphering the Iberian language lies in the fact that post cocturam graffiti in dolia, usually indicate the dolium capacity in amphora quadrantal (~26 litres) and sextarii. Given that the vessel it is intact allows the comparison of its dimensions with other complete dolia with Latin capacity graffiti. Such is the case of the BadalonaÃ¢â‚¬â„¢s dolium, smaller than RuscinoÃ¢â‚¬â„¢s vessel, and with the Ã¢â‚¬Å“stampÃ¢â‚¬Â M XVII (amphorae), not XXVIII as it was published, and XX sextarii (17,4 amphorae). Not only that, Santa PolaÃ¢â‚¬â„¢s dolium, which is bigger, and with the Ã¢â‚¬Å“stampÃ¢â‚¬Â M XXIII (amphorae) and XXIIX sextarii (23, 6 amphorae). Hence, considering the dimensions of the RuscinoÃ¢â‚¬â„¢s dolium, it is between the vessel of Badalona and the one from Santa Pola, is plausible to hypothesize that ogei had the value of 20 amphorae. Everything points to the use of local measurement units (M), almost always in a range between 25 and 35 liters, which coincides with the capacity range of the most common types of transport containers of the time. So, the dolium of Ruscino allows the validation, with inner arguments, the plausibility of the value as an Iberian numeral orÃ‚Â´gei / ogei, which, as up until now, it was only supported for its similarity to the Basque numeral hogei (20), and for the inner combination of complex numerals, such as orÃ‚Â´geirur (23), orÃ‚Â´geikelaur (24) o orÃ‚Â´geiabarÃ‚Â´ (30).
La cella uinaria de la vilÃ‚Â·la romana dels Pompeu (BesalÃƒÂº, la Garrotxa). Aspectes tÃƒÂ¨cnics

Published: February 2025

In 2020, a wine cellar (cella uinaria) was excavated in the Roman villa of Pompei (Besalu, la Garrotxa). It was built on top of the former villa courtyard, once it had already lost its residential functions. It was made up of a minimum of fifty-four buried dolia (dolia defossa) arranged in rows, twelve of which still preserved their bases. In this paper, we try to reconstruct the profile of the containers and determine their typology. We also analyse the graffiti made on the dolia walls, calculate their carrying capacity and identify the different types of repairs made. Finally, based on the data obtained, an interpretation is drawn up to contextualize the cella uinaria within the archaeological sequence of the site.

Published: February 2025

The dolia are present in the villa of Pla de lÃ¢â‚¬â„¢Horta (Sarria de Ter, Girona), from the founding period in the middle of the 1st century BC, a period from which the traces of a cella uinaria are preserved, although very affected by the later reforms. But the reforms that took place from the middle of the 3rd century onwards in the known part of the town are the ones that are best preserved and can be analysed. At this time and, above all, throughout the fourth century, a significant increase in productive structures can be observed, which end up occupying spaces previously used for housing. Thus, the entire area located to the west of the town, where an important torcularium already existed centuries ago, is terraced, configuring an extensive work area directly connected to some of the old residential rooms subsequently, converted into industrial spaces, specifically in warehouses, with dolia. Residue analyses of some of the dolia have confirmed the presence of fats of vegetable origin Ã¢â‚¬â€œ olive oil-.

Published: February 2025

The Roman villa of Pont del Treball Digne is located northeast of the ager of Barcino, very close to the mouth of the River Besos and the Via Augusta. It is a large wine producing centre, of which two torcularia have been documented. The first, with two presses, was built around 40 BC and was replaced at the end of the first century AD by another with six presses, which was in operation until the first half of the fifth century AD. Towards the second half of the fifth century AD, when the residential areas of the villa were converted into productive spaces, a third smaller pressing facility was built. In relation to the first torcularium, several pits of dolia defossa have been documented, some of which would probably correspond to his cella vinaria. Of the second torcularium, his cella vinaria has not been located, although a hypothesis is raised about its location. The set of dolia recovered in its original location corresponds to reused containers, in some cases with a possible change of use. A collection of 27 inscriptions on dolia has been documented in the villa, one of which is complete, referring to its capacity.

Published: February 2025

The archaeological site of Can Cabassa is located to the west of the municipality of Sant Cugat del Valles (Valles Occidental, Barcelona), close to the municipality of Rubi. The excavation uncovered 24.000 m2 of a Roman settlement, founded in the 1st century BC, being developed in extension throughout the high empire, with a progressive growth, being the 4th and 5th century the time of maximum activity of the villa, which was definitively abandoned in the 7th century. Despite the state of destruction in which it was due to agricultural activity, the documented remains are mainly belonging to the fruitful and rustic part of the villa. Of this set it is necessary to highlight a large work yard around which there are different warehouses and spaces, with a pressing room, torcularium, and the cella uinaria with capacity for 120 dolia. During the first half of the 5th century, a certain deterioration of the villa can be observed, further diversifying economic activity by keeping on the exploitation of wine and focusing more on livestock and agriculture. The torcularium and cella uinaria will be abandoned, but one new warehouse will be built in the northwest, of smaller dimensions, of which 16 impressions of dolia have been documented in an area that could fit a maximum of 60. Several seals and capacity marks have been recovered as well as fragments of dolia in which you can see a reuse of them with reparations based on lead.

Since 2005, a Belgian-Italian mission of the UniversitÃƒÂ© catholique de Louvain (UCLouvain) has been working on the excavation of an impressive late antique villa at the site of Aiano, within the municipality of San Gimignano (Siena, Italy). The complex, founded between the end of the 3rd and the beginning of the 4th century AD, was enriched between the end of the 4th and the beginning of the 5th century AD by a polylobate ambulatio surrounding a hexalobate hall. This room underwent various building phases that led it to its current triapsidal appearance. The villa was abandoned at the end of the 5th century AD and after a short time, some productive workshops were established in its disused rooms, which recycled all the decorations of the previous residential complex with a great organisation. The site was then definitively abandoned in the mid-7th century AD. Since 2019 excavation campaign, a new sector of the complex has been partially explored. Three in situ dolia were uncovered in this area. These were emptied and filled with earth, in which some pottery was found, providing a terminus post quem date for the defunctionalisation to the 6th century AD. This contribution will present unpublished data on the presence of dolia in the late roman villa of Aiano, between Late Antiquity and the Early Middle Ages, both in fragments and in situ. It will also be an opportunity to examine the large central pillared room where the dolia were discovered and to examine its functions.
Achmea Kararı Sonrasında Avrupa Birliği Hukukunda İkili Yatırım Anlaşmalarının Değerlendirilmesi
Authors: Şahin Duru Hilal
Published: February 2025

İkili yatırım anlaşmaları (Bilateral Investment Treaties, BITs), uluslararası yatırım hukukunda oldukça önemli bir yere sahiptir. İkili yatırım anlaşmaları; iki devlet arasında, bir akit devletin yatırımcıları tarafından diğer akit devletin topraklarında yapılan yatırımların hükümlerini ve şartlarını belirlemektedir. İkili yatırım anlaşmaları, yatırımdan kaynaklanan risklerin minimize edilmesi veya giderilmesi adına yabancı yatırımcı lehine güvenceler sağlamaktadır. Avrupa Birliği (AB) içi ikili yatırım anlaşmaları (intra-EU BITs), AB üyesi devlet ile sözleşmenin akdedilmesinden sonraki bir tarihte AB’ye katılan üye devlet arasındaki anlaşmalardır. AB hukuku, ulus devletler gibi kapsamlı bir anayasaya sahip değildir. Bunun yerine bir dizi anlaşma ve antlaşmaya dayanmaktadır. AB hukukuna ilişkin anlaşmazlıkların çözümünde de Avrupa Komisyonu ve Avrupa Adalet Divanı da dahil olmak üzere “ulus-üstü” kurumlara sahiptir1. AB Antlaşması’nda belirtildiği üzere, üye devletler; AB hukukun üstünlüğü ilkesini benimsemişlerdir. Bu makalede, AB içi ikili yatırım anlaşmalarının AB hukuku ile uyumlu olup olmadığı incelenecektir. Zira, AB içi ikili yatırım anlaşmaları, akit devletler arasında geçerli (inter-se) yatırımcı-devlet tahkim hükümleri barındırmaktadır. Yatırımcı-Devlet tahkimine ilişkin hüküm, Avrupa Birliği’nin İşleyişine Dair Anlaşma (ABİDA)’nın 344. Maddesi2 ile çatışmaktadır. Bu nedenle yatırımcı-tahkim uyuşmazlık çözüm yöntemini içeren AB içi ikili yatırım anlaşmalarının, AB hukukunun üstünlüğü ve özerk yapısıyla uyumu sorgulanır hale gelmiştir. ABAD (Avrupa Birliği Adalet Divanı)’ın Achmea kararı, AB içi ikili anlaşmaların sorgulandığı ilk davadır. Achmea’ dan sonra diğer AB üye devlet mahkemeleri de bu hususu sorgulamaya başlamışlardır. Achmea’ nın önemli bir diğer sonucu ise, bazı AB üye devletleri arasında imzalanan Fesih Anlaşması’dır. Bu Anlaşma, AB içi ikili yatırım anlaşmalarda yer alan yatırımcı-devlet tahkimine yönelik hükümlerin ve sona erme hükümlerinin (sunset clause) kaldırılmasını içermektedir. Bu makalede Achmea’dan başlayarak AB hukukunda yaşanan önemli gelişmeler ortaya konulacaktır. AB hukuku ile AB içi yatırımcı-devlet tahkim hükümleri arasındaki çatışma, uluslararası hukukun çatışma kuralları başta olmak üzere, uygulanabilir kurallar ortaya konularak aydınlatılmaya çalışılacaktır.

Published: February 2025

No tumultuado ano letivo e civil de 2020, marcado pela desafiadora pandemia da COVID-19, os educadores enfrentaram adversidades notáveis, especialmente no contexto de um país em desenvolvimento como o Brasil. A implementação do ensino remoto emergencial, sobretudo nas instáveis condições de acesso tecnológico tanto dos educandos quanto dos professores, exacerbou as fragilidades já existentes na estrutura de ensino e aprendizagem, especialmente na educação básica pública. Este cenário complexo é agravado ao analisarmos a realidade de uma Escola Itinerante em uma cidade do interior do Paraná, onde a falta de suporte governamental eficaz para acesso à educação tornou o Ensino Remoto Emergencial particularmente desafiador para essa parcela vulnerável da sociedade. Este artigo explora o processo de ensino-aprendizagem na disciplina de Língua Portuguesa, no 8º ano da Escola Itinerante Valmir Mota de Oliveira, durante o primeiro ano da pandemia. Para essa análise, além da revisão bibliográfica, são utilizados os pareceres circunstanciados, documentos anuais produzidos na escola em substituição aos boletins tradicionais, que abrangem a vivência dos educandos e as práticas pedagógicas/docentes no processo de aprendizagem. A metodologia adotada inclui a análise de conteúdo para proporcionar uma compreensão mais aprofundada desse contexto educacional desafiador. Da marca que ao longo dos anos luta para sobreviver às atuais situações econômicas do país.
Post-return stroke VHF electromagnetic activity in north-western Mediterranean cloud-to-ground lightning flashes
Authors: Kolínská Andrea , Kolmašová Ivana , Defer Eric , Santolík Ondřej , Pédeboy Stéphane
Published: February 2025

Abstract. We investigate properties of the electromagnetic activity following the first lightning return stroke (RS), using concurrent observations from the SLAVIA (Shielded Loop Antenna with a Versatile Integrated Amplifier) sensor, the SAETTA (Suivi de l'Activité Electrique Tridimensionnelle Totale de l'Atmosphère) Lightning Mapping Array (LMA) and the METEORAGE LF (low-frequency) network in the Corsica region. From the data collected between September and December 2015, we selected 66 negative cloud-to-ground (−CG) and 26 positive cloud-to-ground (+CG) lightning flashes in the north-western Mediterranean region. In the SAETTA data, we observe a decrease in the very high frequency (VHF) radiation rate and the VHF power, as recorded within a typical 80 µs time window at the LMA stations, immediately after the RS pulse in 59 −CG flashes. Contrastingly, we show that all examined +CG flashes exhibit a rapid increase in the VHF radiation rate and the VHF power immediately after the RS. We suggest a possible explanation of this phenomenon by considering the step-like propagation of a negative part of the bidirectional leader starting at the top end of the positive lightning channel inside the thundercloud, emitting electromagnetic radiation across a broad frequency spectrum.
Totten Ice Shelf history over the past century interpreted from satellite imagery
Authors: Miles Bertie W. J. , Li Tian , Bingham Robert G.
Published: February 2025

Abstract. Totten Glacier is currently the largest source of mass loss in the East Antarctic Ice Sheet and it is projected to be a large source of sea-level rise over the coming century. The glacier has been losing mass for decades and inland thinning was detected in the earliest satellite-altimetry observations in the early 1990s, but when the glacier first started losing mass remains unknown. We calculate decadal ice-speed anomalies to confirm that Totten Glacier has not undergone sustained acceleration since at least 1973. Together with observations of grounding-line retreat from 1973–1989, we confirm that the glacier was already out of balance in the 1970s. Surface undulations form on the Totten Ice Shelf adjacent to an ice rumple near the grounding line in response to time-varying melt rates and are preserved downstream for several decades. From utilizing the full suite of Landsat imagery, we produce a century-long record of surface-undulation formation that we interpret as a qualitative record of basal-melt-rate variability. An anomalous ~20-year absence of undulations associated with the mid-20th century manifests a period when ice passing over the ice rumple was pervasively thinner, and may represent an anonymously warm period that triggered the onset of modern-day mass loss at Totten Glacier. Our results highlight that the currently available ~30-year satellite altimetry records are not long enough to capture the full scale of decadal variability in basal-melt rates and mass-loss patterns.
Managed aquifer recharge and exploitation impacts on dynamics of groundwater level and quality in northern China karst area: Quantitative research by multi-methods
Authors: Cao Han , Qian Jinlong , Chen Huanliang , Liu Chunwei , Lyu Minghui , Gao Shuai , Dong Weihong , Hu Caiping
Published: February 2025

Abstract. Managed aquifer recharge (MAR) is an effective way to counter groundwater level decline and spring depletion caused by excessive groundwater exploitation in karst areas. However, the unique characteristics of karst groundwater systems make the groundwater quantity and quality more susceptible to human activities, posing challenges for MAR research. This research employed multi-methods including numerical simulations, isotope analysis, infiltration tests, flow monitoring and tracer tests to quantitatively analyze the impacts of MAR and groundwater exploitation on the dynamics of groundwater level and quality in a typical northern China karst area, the Baotu Spring area in Jinan City. First, the percentage of surface water recharge in karst groundwater was calculated using isotope data with the improved two-end-member mixing model. Next, the quantitative relationship between volume of released water and actual recharge was established with data from infiltration tests and flow monitoring. Then, the actual groundwater flow velocity and effective porosity of the karst aquifers were calculated with former tracer test isochrone maps. Finally, the impacts of MAR and groundwater exploitation on dynamics of groundwater level and quality were quantitatively analyzed with a groundwater flow-solute transport model for the area. The results indicate that the MAR and groundwater exploitation in the Baotu Spring area have significantly impacted karst groundwater levels and quality. These complementary methods enhance the accuracy of decisions in MAR and groundwater exploitation.
Assessing Climate Modeling Uncertainties in the Siberian Frozen Soil Regions by Contrasting CMIP6 and LS3MIP
Authors: Luo Zhicheng , Ji Duoying , Ahrens Bodo
Published: February 2025

Abstract. Climate models and their land components still show pervasive discrepancies in frozen soil simulations. Contrasting the historical runs of seven land-only models of the Land Surface, Snow, and Soil Moisture Model Intercomparison Project (LS3MIP) with their Coupled Model Intercomparison Project Phase 6 (CMIP6) counterparts allows quantifying the contributions of the land surface parameterization scheme and the atmospheric forcing to the discrepancies. The simulation capabilities are assessed using observational data from 152 sites in Siberia and reanalysis data. On average, the 0.2-m soil temperatures in the CMIP6 simulations are 5.4 °C colder than the observations if the simulated soil temperature drops below -5 °C. The LS3MIP simulations are even colder with a bias of -6.7 °C. In the winter months (December, January, and February), the LS3MIP ensemble diversity in 2-m temperature is less than the CMIP6 diversity (0.8 °C vs 3.2 °C). In contrast, the diversity of winter 0.2-m soil temperatures is larger in the LS3MIP ensemble (5.7 °C) than in the CMIP6 ensemble (3.6 °C). For permafrost sites, the spatial correlation of the simulations of winter soil temperature against observation is not better than 0.7, and spring/autumn spatial correlations of snow depth are less than 0.75 for the CMIP6 models. The biases of 2-m temperature have a different sign and are amplified in magnitude compared to the biases of the soil temperatures, especially below 0 °C. Four of the climate models and their land components underestimate the snow insulation effect. We conclude that land surface models struggle to well simulate soil temperatures and snow depth under low-temperature conditions. The CMIP6 models tend to compensate for errors in their land component by errors through errors in the atmospheric model component. In shallow snow depth (0 to 0.2 °C) cases, all models show between 1 to 8 °C less air-soil temperature difference than in situ data. Therefore, a better representation of surface-soil insulation is essential for improvements in frozen soil land modeling.

Published: February 2025

El concepto del envejecimiento ha ido evolucionando a lo largo de la historia. Las primeras alusiones hacían referencia a enfoques biológicos, sanitarios y/o relacionadas con el empleo. Posteriormente, el concepto se ha ido ampliando hacia enfoques con carácter integral, multidimensional y transversal, como son el Envejecimiento Activo (OMS, 2002) y/o el Envejecimiento Saludable (OMS, 2020).
El propósito de este trabajo es visibilizar el papel de la universidad en la promoción del envejecimiento activo y saludable. La universidad, en el marco de su responsabilidad social, puede desarrollar un papel destacado en la optimización del envejecimiento, a través de sus funciones de investigación, docencia y extensión. El aprendizaje-servicio (ApS) se revela como una metodología idónea para posibilitar la participación activa de la universidad en su entorno al tiempo que fortalece los aprendizajes significativos.

Aim. To study the perinatal outcomes of women, living in the Khatlon region with late spontaneous preterm birth (LSPB).

Material and methods. 146 women with late spontaneous preterm birth were studied, according to the gestational age at which the birth occurred: subgroup A - gestational age 34 weeks + 6 days (27 women), subgroup B - gestational age 35 weeks + 6 days (51 women), subgroup B – gestational period 36 weeks + 6 days (68 women). Parametric and nonparametric methods of biological statistics (Student and Whitney-Munny tests).

Results. One in five newborns born to mothers with late spontaneous preterm labour was found to be small for gestational age, with fetal growth restriction diagnosed in 75.8% of these cases. A statistically significant reduction in mean Apgar scores at 1 and 5 minutes was observed in neonates born at 34+6 weeks’ gestation. Respiratory failure was the cause of early neonatal mortality in 56.3% of cases. In the structure of early neonatal morbidity, respiratory failure is a leading cause, with its frequency and severity depending on gestational age. A strong inverse correlation was found between gestational age and the incidence of respiratory failure in the early neonatal period in neonates born to mothers with late spontaneous preterm labour and fetal growth restriction.

Conclusion. It is advisable to further conduct research on the effectiveness of differentiated approaches to preventing respiratory distress syndrome in late preterm birth.

Aim. To determine the share of patients with recent HIV infection in order to plan prevention programs.

Materials and methods. Statistical data from all newly identified HIV cases in 2022 were analysed to determine the estimated time of HIV infection using the ELISA method. The study utilised a variety of reporting and medical documentation, including epidemiological records, outpatient medical records of people living with HIV, and data from the laboratory module of the electronic HIV case surveillance system. Statistical analysis of new cases of HIV infection was conducted within the framework of the electronic HIV case surveillance system of Tajikistan.

Results and discussion. In 2022, a total of 1 037 new cases of HIV infection were identified and registered in the Republic of Tajikistan, of whom 975 (94.0%) were aged 18 years or older. A total of 923 persons participated in the study of the timing of HIV infection, representing 94.5% of all newly identified HIV cases among persons aged 18 years and older. The proportion of recent HIV infections among newly identified cases in Tajikistan in 2022 was 18.3%.

Conclusion. Across the country, the proportion of new HIV infections remained at the same level as in 2018, with a slight increase observed in 2022. As in previous years, the highest proportion of recent HIV infections was observed in the Khatlon region (27.3%). A higher proportion of new HIV infections was observed in the under-25 age group (34.9%), which is more than twice as high as in the 25+ age group.

REPRÉSENTATION AUDIOVISUELLE DANS LE PROCESSUS DE PATRIMONIALISATION D'UN PAYSAGE AGRICOLE PÉRIURBAIN

Published: February 2025

L'utilisation de l'eau comme bien collectif par les communautés d'irrigants en milieu urbain est un élément fondamental de la matérialité et des représentations sociales des paysages agricoles historiques de grand intérêt. La rupture de l'équilibre et de la complémentarité entre ville et campagne, provoquée par une croissance urbaine démesurée et ignorante des valeurs en jeu, a entraîné la perte irréparable de sols à forte capacité agrologique et la subordination de l'utilisation de l'eau à la logique et aux intérêts urbains. Dans ce contexte, cet article traite d'une initiative locale pour défendre et activer les multiples fonctions, notamment la fonction alimentaire, des jardins maraîchers du sud de la région métropolitaine de Madrid. Dans cette initiative, menée par le Parc Agraire de Fuenlabrada, la patrimonialisation du paysage de l’eau par les paysans et les populations locales intègre une composante audiovisuelle liée au projet web doc transmedia Likuit Water Cultures, qui vise à approfondir les différentes relations que les communautés établissent avec l'eau, à partir d'une expérience interactive et sensorielle. Le langage audiovisuel transmédia est une forme de représentation étroitement liée à l'expérience sensible du paysage, capable de refléter les éléments identitaires du récit sur l'eau et le paysage.
LA PERIURBANISATION AU NIVEAU DE LA MITIDJA OUEST
Authors: BOUSTIL Feriel
Published: February 2025

Dans la plaine occidentale de la Mitidja au nord de l’Algérie, le développement de l’habitat a évolué à partir des villages coloniaux, accompagné récemment par des lotissements privés et des habitats verticaux. Ces transformations reflètent les impacts de la tragédie nationale, de la restructuration et des politiques agricoles algériennes. Ce processus a déclenché une micro-urbanisation progressive, questionnant l’enracinement des nouveaux habitants et leurs formes d’appropriation des espaces, en écho aux théories de Jacques Lévy.
Les nouvelles urbanisations périphériques, bien qu’améliorant la qualité de vie pour certains, génèrent des inégalités spatiales, temporelles et sociales, accentuant la ségrégation socio-spatiale. Ces transformations évoquent l’apparition d’une identité spatiale comparable aux zones périurbaines françaises des années 1970. Ce phénomène soulève des interrogations sur l’émergence d’un urbanisme endogène et sur son impact économique, social et territorial face à la domination urbaine des villes voisines.
LES PAYSAGES CONSTRUITS A TRAVERS LES GALERIES D’EAU SUR LES DEUX RIVES DE LA MEDITERRANEE ET AU MOYEN-ORIENT

Les galeries d’eau renvoient à une terminologie riche et diversifiée dont aflaj, foggaras, qanâts, termes qui désignent des techniques et des pratiques ancestrales rencontrées dans les écosystèmes arides, notamment dans le Moyen-Orient et sur les deux rives de la méditerranée. Ces techniques et pratiques millénaires d’une grande ingéniosité consistent en une gestion efficace des ressources en eau en utilisant les systèmes de drainage souterrains des aquifères. Une valorisation et des échelles de distribution sont organisées en faveur des utilisateurs et des usagers communautaires.
On tentera tout au long de ce travail d’identifier des vestiges de galeries d’eau et l’implication de ces dernières dans la genèse de paysages typiques. Il s’avère que ces systèmes génèrent et animent des vies humaines et non humaines dans des pays aussi différents que l’Iran, Oman, la Tunisie et l’Espagne. La construction des paysages à travers ces infrastructures se matérialise notamment par les oasis, les forts, les moulins à eau, les réservoirs d’eau et les tours à vent. Cette recherche propose une approche spatiale des galeries d’eau issues de contextes différents et étudie les méthodes et les matériaux de construction des tunnels souterrains et de leurs édifices annexes. Ces pratiques traditionnelles et de savoir-faire anciens émanent de peuples marqués par leur diversité géographique, sociale et culturelle, édifiant ainsi un patrimoine paysager qui défie les limites territoriales et retrace les conquêtes de l’Homme sur l’aridité de la nature dans sa quête de stabilité et d’expansion, depuis le Moyen-Orient jusqu’aux deux rives de la Méditerranée. Ce patrimoine, à la fois commun et varié, fait face à plusieurs enjeux qui parfois en menacent l’existence ; pour cela, il est nécessaire de le revaloriser et de l’intégrer dans des contextes spatiaux profitables (culturellement et économiquement), vivables et surtout durables.
