Collective Creativity and Complexity in Urban Laboratories: El Campo de Cebada

Cities are complex systems requiring urban design models that balance order and disorder. Collective creativity initiatives engage citizens in these processes, empowering bottom-up approaches that prioritize people and social well-being within urban development. This paper investigates an ‘Urban Laboratory’ as a case study, examining the potential of collective creativity to address urban complexity. The successful and ongoing project ‘El Campo de Cebada’ in Madrid, Spain, demonstrates how a community transformed a vacant lot into a vibrant social hub. The phases of this study include case selection, data collection, data analysis, and presentation of the results. This study identifies key enabling factors, including agents, management, social dynamics, infrastructure, and actions. These insights offer a methodological framework for designing future collaborative, resilient, and inclusive urban spaces, addressing the complex needs of communities within our cities.

The Lost Shantytowns of Barcelona

Shantytowns still existed in many of Southern Europe’s major cities in the second half of the 20th century, although many have now been demolished. The purpose of this article is to highlight the history and evolution of some of the main shantytowns that remained in Barcelona in the mid-1970s, track their subsequent demolition, and reflect on the fate of the shanty dwellers. This form of self-build housing, usually lacking in basic services, played a vital role in providing shelter for immigrant families and the urban poor. A strong neighbourhood identity existed in many of these shantytowns, and national and local policies that aimed at their demolition and the re-housing of residents, often in low-quality housing blocks, proved problematic. The shantytowns studied here are La Perona, the Tres Turons, Campo de la Bota, and Ramon Casellas, which together comprised over 2000 shanty dwellings in the 1970s. Drawing on photographs taken at the time and existing literature, and using recent images from Google Earth, the demise of these shantytowns is examined, and the policies and plans that determined their fate are discussed. This article finds that the shanty dwellers experienced mixed fortunes, some being forcibly removed and re-housed in tower blocks with associated social-economic problems, whilst others played an active part in the design of replacement housing, implemented in situ where the shanty dwellings once existed. This article contributes to existing studies on shantytowns in Barcelona, which received scant attention from academics at the time, and which only now are being recognised as an important aspect of Barcelona’s urban history.

On the rocks: Biogeography and floristic identity of rocky ecosystems in eastern South America

AbstractThe geodiversity of rocky ecosystems includes diverse plant communities with specific names, but their continental‐scale floristic identity and the knowledge on the role of macroclimate remain patchy. Here, we assessed the identity of plant communities in eastern Brazil across multiple types of rocky landscapes and evaluated the relative importance of climatic variables in constraining floristic differentiation. We provided lists of diagnostic species and an assessment of the conservation status of the identified floristic groups. We compiled a data set of 151 sites (4498 species) from rocky ecosystems, including campos rupestres, campos de altitude, granitic‐gneiss lowland inselbergs, and limestone outcrops. We used unsupervised clustering analysis followed by ANOSIM to assess floristic groups among sites. We performed a random forest variable selection to test whether the identified floristic groups occupy distinct climatic spaces. Six groups (lithobiomes) segregated floristically according to lithology and climate. Alongside campos de altitude and limestone outcrops, inselbergs were divided according to the biome in which they occur (Atlantic Forest or Caatinga), and campos rupestres were largely segregated according to their lithological matrix (ironstone or quartzitic). Plant communities of Caatinga inselbergs were more similar to limestone outcrops, while Atlantic Forest inselbergs communities resembled campos de altitude. The composition of plant communities on outcrops seems to be largely constrained by lithology, but climatic factors are also meaningful for sites with similar lithology. The current network of protected areas does not cover these unique ecosystems and their floristic heterogeneity, with Caatinga inselbergs and limestone outcrops being the least protected.

Marine resource exploitation and human settlement patterns during the Neolithic in SW Europe: stable oxygen isotope analyses (δ18O) on Phorcus lineatus (da Costa, 1778) from Campo de Hockey (San Fernando, Cádiz, Spain)

In recent decades, investigations in the southern Iberian Peninsula have increased our understanding of the socio-economic impact of the spread of the Neolithic in southwestern Europe, including changes in marine resources exploitation. Nevertheless, considerable uncertainty still exists around the seasonality of such subsistence systems and the putative role of marine fish and shellfish to the evolving agro-pastoral economies. Earlier studies on the European Atlantic coast (including Iberia) have shown that the stable oxygen isotope (δ18O) values from the topshell Phorcus lineatus (da Costa, 1778) can be reliably used to derive seasonal sea surface temperatures (SST) during its lifespan. This information can be used by archaeologists to estimate the seasonality of mollusc collection in the past, and to shed light into settlement and subsistence patterns. This paper presents the results of a stable isotope study on archaeological shells of P. lineatus recovered from the Neolithic settlement of Campo de Hockey (Cádiz, Spain). We analysed shells from both funerary and residential contexts and found that P. lineatus was consumed year-round, but with a stronger preference during winter. Our results therefore contribute to advance our understanding of the role of coastal environments in early farming societies of southwestern Europe.

Why didn’t we know this before? Challenging the Culture of the Transition through the concentration camp at Castuera

ABSTRACT In post-conflict democracies with a recent past of intrastate violence and social fracture, depictions of the nation’s history play a role in efforts toward reconciliation. Public institutions act as agents in constructing the narrative of the country’s traumatic past, thus controlling public display of trauma and determining what is deemed essential to remember and what is not. In the case of contemporary Spain, the politics of oblivion normalized during the Transition produced an absence of democratic memory in Spanish education. This contribution examines the pedagogical possibilities of Spanish concentration camps, namely the concentration camp at Castuera (Badajoz), where the Asociación Memorial Campo de Concentración de Castuera (AMECADEC) has been working on the implementation of educational visits and the development of didactic guides. As with many other Spanish concentration camps, Castuera displays a lack of architectural remains, which poses a challenge to the concept of “ruins”. The activities developed by AMECADEC propose an alternative articulation of pedagogy and trauma, based on the educational possibilities of ruins and their political and material absences. As such, these activities offer an example of how to engage the processes of symbolization and memory intervention needed to create new historical narratives about Spain’s current democracy, challenging the Culture of the Transition.

Overrepresentation of Students from a Migrant Background in Special Education: Promoting Inclusive and Equitable Education

This study analyses the overrepresentation of students from a migrant background in special education in the stage of primary education, in the region of El Campo de Gibraltar (Southern Spain). This phenomenon poses significant concerns in terms of educational equity and discrimination, as well as questions about the possible underlying causes. It was decided to address this issue from a qualitative methodology through semi-structured interviews with 16 educators of educational centres that have a significant number of students from a migrant background. The results show the need of educators for specific training in attention to diversity. Likewise, many migrant families come to Spain due to the lack of adequate attention that their children receive in their home countries. Lastly, language and cultural barriers were identified, which allow for biased assessments and subjective decisions that result in the referral of students from a migrant background to special education from a multidimensional perspective. Therefore, it is fundamental to provide training to professionals, overcome the language and cultural barriers and ensure that the necessary resources are available, thus guaranteeing an inclusive and equitable education for all students, regardless of their origin.

Sampling methods may drive short-term groundwater nitrate variability in an irrigated watershed connected to a coastal lagoon (Campo de Cartagena-Mar Menor, SE Spain)

This study highlights concerns regarding the reliability of groundwater nitrate data used in official surveys, such as within the EU-mandated Water Framework Directive (WFD). The focus is on the Campo de Cartagena - Mar Menor hydrosystem in Spain, a region known for its intensively irrigated watershed and eutrophicated lagoon, where monitoring the evolution of nitrate contamination in surface and groundwater is crucial but challenging due to the risk of inconsistent characterization leading to erratic remediation measures. The study employed an experimental approach in private wells that belong to a longstanding official nitrate survey network marked by irregular sampling practices. Importantly, these wells lacked comprehensive design documentation and were frequently used by farmers. The study aimed to evaluate the representativity of dissolved nitrate measurements in such an emblematic case, while investigating the source of the water using geochemical and isotope tracers. This assessment considered the effects of different sampling techniques (bailer or pumping) and sampling parameters (depth and time), acknowledging actual practices. The research highlights several key findings. Firstly, the bailer sampling method proved to account for a substantial portion of the observed variation in nitrate content. Secondly, in some cases, pumping introduced contributions from different water horizons, complicating the interpretation of nitrate data. Thirdly, alterations in the sampling protocol had a notable impact on the resulting nitrate measurements. Furthermore, the study emphasized a critical issue: the lack of analytical uncertainty estimation in official surveys introduces significant bias in result interpretation, with discrepancies exceeding 100 mg/L in four of the six wells analyzed. This underscores the pressing need for improved sampling protocols, dedicated borehole infrastructure and precise data interpretation. Given the potential unreliability of some official groundwater nitrate data shared under EU or other regulations, with corresponding economic and environmental impacts, the study recommends meticulous verification before transmitting data.

A new Malaxis (Orchidaceae: Malaxidinae) from the Campos de Altitude of the Atlantic rainforest in southern Brazil

Malaxis ybytus is proposed as a new species from the wetlands of the Campos de Altitude of the Atlantic rainforest of south Brazil, Serra do Araçatuba\Papanduva mountain chain. It is described, illustrated, and compared with other similar species. The new species is similar to Malaxis cipoensis and Malaxis sertulifera, but it is recognised by its flat to slightly conduplicate leaves, densely congested inflorescence with small flowers bearing free lateral sepals and four foveas in the lip. Due to the high degree of endemism in this environment, the few collection records and the anthropic pressure in the region, we infer that the species is critically endangered (CR) based in criterium D of the IUCN.

Short-Term Forecasting of Ozone Concentration in Metropolitan Lima Using Hybrid Combinations of Time Series Models

In the modern era, air pollution is one of the most harmful environmental issues on the local, regional, and global stages. Its negative impacts go far beyond ecosystems and the economy, harming human health and environmental sustainability. Given these facts, efficient and accurate modeling and forecasting for the concentration of ozone are vital. Thus, this study explores an in-depth analysis of forecasting the concentration of ozone by comparing many hybrid combinations of time series models. To this end, in the first phase, the hourly ozone time series is decomposed into three new sub-series, including the long-term trend, the seasonal trend, and the stochastic series, by applying the seasonal trend decomposition method. In the second phase, we forecast every sub-series with three popular time series models and all their combinations In the final phase, the results of each sub-series forecast are combined to achieve the results of the final forecast. The proposed hybrid time series forecasting models were applied to four Metropolitan Lima monitoring stations—ATE, Campo de Marte, San Borja, and Santa Anita—for the years 2017, 2018, and 2019 in the winter season. Thus, the combinations of the considered time series models generated 27 combinations for each sampling station. They demonstrated significant forecasts of the sample based on highly accurate and efficient descriptive, statistical, and graphic analysis tests, as a lower mean error occurred in the optimized forecast models compared to baseline models. The most effective hybrid models for the ATE, Campo de Marte, San Borja, and Santa Anita stations were identified based on their superior out-of-sample forecast results, as measured by RMSE (4.611, 3.637, 1.495, and 1.969), RMSPE (4.464, 11.846, 1.864, and 15.924), MAE (1.711, 2.356, 1.078, and 1.462), and MAPE (14.862, 20.441, 7.668, and 76.261) errors. These models significantly outperformed other models due to their lower error values. In addition, the best models are statistically significant (p < 0.05) and superior to the rest of the combination models. Furthermore, the final proposed models show significant performance with the least mean error, which is comparatively better than the considered baseline models. Finally, the authors also recommend using the proposed hybrid time series combination forecasting models to predict ozone concentrations in other districts of Lima and other parts of Peru.

Morphological, geographic and ecological evidence support a new species of Chusquea subg. Swallenochloa (Poaceae, Bambusoideae, Bambuseae) from Parque Nacional do Caparaó, Brazil

Specimens from the Serra do Caparaó (border of Minas Gerais and Espírito Santo states in Brazil) previously treated as Chusquea aff. heterophylla were compared with C. heterophylla. We found differences in macromorphology (including habit, culm leaf persistence and indument, subsidiary branch number, foliage leaf indument on sheath and blades, and spikelet size and bract proportions), abaxial micromorphology of the foliage leaf blades (including silica cell shape, prickle hair shape, bicellular microhair relative size and proportion of its cells, macrohair presence, long cell papillar shape, and subsidiary cell papillar shape and orientation) and in geographic distribution and habitat. These differences were considered enough to describe Chusquea riparia as a new species herein considered as microendemic to the Parque Nacional do Caparaó, growing only in riparian areas of montane Atlantic forest and campos de altitude. We provide illustrations, maps, taxonomic and phenological comments on the new species, and a key to the species of C. subg. Swallenochloa from the Parque Nacional do Caparaó.

Looking similar but all different: Phylogenetic signature of Brazilian rocky outcrops and the influence of temperature variability on their phylogenetic structure

Abstract Old, climatically buffered, infertile landscapes (OCBILs) have a disjunct yet wide distribution worldwide. Old lineages, rare and geographically restricted species, generally characterise these landscapes. Although the last decade provided evidence supporting the OCBIL theory, many studies are biased towards local scales, woody plants and specific OCBILs. Therefore, broad‐scale investigations across different types of OCBILs are needed. We used 5186 flowering plant species (woody and herbaceous) distributed across 129 rocky outcrop sites in Brazil to investigate (1) the relative influence of climate on the phylogenetic diversity and structure of OCBILs; (2) their phylogenetic signature; (3) whether vegetation type influences phylogenetic diversity and structure of OCBILs after controlling for climate; and (4) the OCBILs' evolutionary median community age. We found that rocky outcrops exhibit lower than expected phylogenetic diversity and are home to plant communities composed of closely related species (i.e. phylogenetic clustering) relative to the reference species pool, primarily due to temperature seasonality. Each rocky outcrop shows a distinct phylogenetic signature, indicated by plant families with more descendant species than expected by chance. Even after controlling for climate, phylogenetic diversity and structure remain low and clustered in most rocky outcrops. The median community age estimated at the species level is lower in campos de altitude than in other rocky outcrops. Synthesis. We show that the influence of climate seasonality is pervasive in the phylogenetic diversity and structure of Brazilian rocky outcrops at different taxonomic levels. We also show that the phylogenetic signature of rocky outcrops comprises a mix of relatively old and young overrepresented plant families whose descendants contribute to their low phylogenetic diversity and phylogenetic clustering. Overall, the combination of low phylogenetic diversity, phylogenetic clustering and comparably low median community age across Brazilian rocky outcrops indicates that, on average, these OCBILs are subjected to strong environmental constraints and serve as arenas of recent diversification rather than a steady accumulation of taxa. Therefore, these findings indicate different OCBILs as hotspots for various plant lineages and species.

Soil toxicity in a protected area in Brazil: Cytotoxic, genotoxic, and toxic effects

The Campos de Palmas Wildlife Refuge (CPWR) (Brazil) is a full protection Conservation Unit (CU) formed by private properties, where the use of land and natural resources are allowed sustainably according to the rules of the CU Management Plan. Inadequate practices of land use and occupation within this CU can affect its quality and the organisms that depend on them. Considering the above, the objective of the present study was to biomonitor different land uses and occupations within the CPWR and its surroundings, during the four seasons of a year, using the bioindicators Allium cepa (cytotoxicity and genotoxicity tests) and Eisenia fetida (leakage test). The soil samples were collected in areas of silviculture, agriculture, and native grasslands within the CU and agriculture outside the limits of the CPWR. The use by silviculture (spring) and native grassland (summer) showed cytotoxic effects for A. cepa. The use by agriculture outside the CPWR (spring) showed genotoxic effect and stimulation of mitotic cell division. For the animal bioindicator, the use by agriculture within the CPWR (winter), native grassland (autumn and spring), silviculture (autumn and spring), and agriculture outside the CU (spring) showed a toxic effect. A PCA analysis showed a correlation between the results of toxicity, cytotoxicity, and genotoxicity with the presence of macronutrients and metals in the evaluated soil samples. Possibly influenced by their soil composition characteristics (silviculture and native grassland) or the management of agricultural areas. In addition, samples from the rainy season (spring) showed higher ecotoxicity. These results show that biomonitoring through different organisms is important for evaluating environmental quality and indicate the need for the implementation of preventive measures in the CPWR to avoid the toxic, cytotoxic, and genotoxic effects found. They also ensure the integrity of this CU and the active protection of the environment and biodiversity.

Avispas sociales (Hymenoptera: Vespidae) asociadas a plantaciones de Eucalyptus sp. en un Campo de Altitud situado en el sur del Estado de Minas Gerais, Brasil

In Brazil, there is little information about social wasp communities in Altitude Fields (Campos de Altitude), a phytophysiognomy of the Atlantic Forest with a high rate of endemism, which is being altered and reduced in area by human activities, such as the cultivation of Eucalyptus spp. Therefore, the present study aimed to inventory the species of Polistinae (Vespidae) presente in an Altitude Field associated with Eucalyptus sp. plantations in the municipality of Poços de Caldas, Southern Minas Gerais, Brazil. The study was conducted in Morro do Ferro, central region of the Poços de Caldas Plateau, from 2020 to 2021, using active search and Malaise traps. Thirteen species of social wasps were recorded, which have a wide geographic distribution, and explore anthropic environments, such as agricultural areas, pasture and Eucalyptus sp. plantations. Many of them behave as synanthropic, suggesting this altitude field to be a degraded area in Poços Caldas, MG. However, further studies must be carried out in the region, in order to know and preserve these remaining ecosystems.

Classification of 2007 Winter Mist and Fog in São Paulo City, Brazil

Mist and fog observed at the Meteorological Station of the Institute of Astronomy, Geophysics and Atmospheric Sciences of the University of São Paulo (EM/IAG) in the southeastern part of São Paulo city in the winter of 2007 were classified according to its formation processes: advection or radiation. Meteorological data from EM/IAG, Congonhas Airport and reanalysis from the European Center for Medium-Range Weather Forecast, as well as radiosondes from Campo de Marte Airport were used. In the 1981-2015 climatology, it was observed that these phenomena are more frequent in the winter, with an average of 11 events per month. For the winter of 2007, 21 advection and 28 radiation events were detected, with radiation fog occurring more frequently in June (13) and advection fog, in August (12). The South Atlantic Subtropical High favored the formation of radiation events in 24 cases; 15 of which had the contribution of humidity advected by the sea breeze. Post-frontal anticyclone was associated with the remaining 25 cases, of which 15 were classified as advection. Four cases were chosen for a more detailed analysis. On July 2, 2007, radiation mist occurred, with the injection of moisture by the sea breeze; the next day, there was also radiation mist, however, with no sea breeze. On the 20th of July, fog was caused by advection of humidity with north/northeast winds coming from the Serra da Cantareira and on the 27th, advection mist developed due to the intensification of winds associated with the movement of a post-frontal anticyclone.

A parsimonious methodological framework for short-term forecasting of groundwater levels

Groundwater plays a significant role as a strategic resource in reducing the impact of droughts. In spite of its importance, there are still many groundwater bodies in which there is not enough monitoring data to define classic distributed mathematical models to forecast future potential levels. The main aim of this study is to propose and evaluate a novel parsimonious integrated method for the short-term forecasting of groundwater levels. It has low requirements in term of data, and it is operational and relatively easy to apply. It uses geostatistics, optimal meteorological exogenous variables and artificial neural networks. We have illustrated our method in the aquifer “Campo de Montiel” (Spain). The analysis of optimal exogenous variables revealed that, in general, the wells with stronger correlations with precipitation are located closer to the central part of the aquifer. NAR, which does not consider secondary information, is the best approach for 25.5 % of the cases and is associated with well locations with lower R2 between groundwater levels and precipitation. Amongst the approaches with exogenous variables, the ones that use effective precipitation have been selected more times as the best experiments. NARX and Elman using effective precipitation had the best approaches with 21.6 % and 29.4 % of the cases respectively. For the selected approaches, we obtained a mean RMSE of 1.14 m in the test and 0.76, 0.92, 0.92, 0.87, 0.90, and 1.05 m for the forecasting test for months 1 to 6 respectively for the 51 wells, but the accuracy of the results can vary depending on the well. The interquartile range of the RMSE is around 2 m for the test and forecasting test. The uncertainty of the forecasting is also considered by generating multiple groundwater level series.
