A segunda vida da Praia dos Espanhóis: dançarinos, pescadores e turistas no sul de Portugal

Abstract: In this text, we deal with proccesses of appropriation of space in the Dam of Póvoa (Portugal) using a dwelling perspective (Ingold 2009) over the territory. The reconversion of innactive spaces in rural areas into leisure-related ones in a quite common practice in contemporary times.The Spaniards beach is one of the local names given by locals to the Dam of Póvoa (Castelo de Vide), in northern Alentejo (Portugal). In the collective memory of the residents, the Dam (built in the 1920’s) is remembered for the many flowers surrounding the area. This Garden-style aesthetics has outlived the initial function of the Dam (to produce electric power). From the 1960’s to the 1980’s, it was also a popular leisure space for Spanish and Portuguese people. It is not a beach, but being inland, it was the closest thing to a beach the residents had. The centrality of this leisure space in the area only decayed after the construction of swimming pools in the nearby towns. Early in the begginning of 21st century a fire destroyed part of the natural floral landscape of the dam. Abandoned for some years, the place has still been appropriated by leisured people in day-trips (for sight-seeing, pic-nics), fishing competitions, caravan soujorns, and, since 2013, in a music and dance festival named Andanças (www.andancas.net). The research that underlies this paper was carried out between 2013 and 2016 by a team of anthropologists. An ethnography of the Dam and its uses, and of the festival and its participants was carried out. In our working-paper we higlight the main research findings achieved.

Key words: cool night index, thermal amplitude, MCC System for World Viticulture, zoning, quality. RESUME Le régime thermique en période de maturation du raisin est l?une des variables déterminantes de la coloration du raisin et de la richesse en arômes, anthocyanes et polyphénols des vins. L?objectif du travail est de caractériser le régime thermique, notamment la fraîcheur des nuits et l?amplitude thermique au cours de la maturation, au niveau du climat viticole mondial, sur une base des données de 100 régions viticoles dans 30 pays, obtenue par l?intermédiaire de l?Organisation Mondiale de la Météorologie - OMM. Plusieurs indices climatiques viticoles ont été calculés: l?Indice de Fraîcheur des Nuits ?IF (ºC), l?Indice Héliothermique de Huglin ?IH (ºC) et l?Indice de Sécheresse ?IS (mm) du Système de Classification Climatique Multicritères Géoviticole, et l?amplitude thermique moyenne en août et septembre Aa-s (ºC). Egalement, sur la période véraison-récolte ?v-r(moyenne des 30 jours précédant la date de récolte, estimée sur la base d?un Indice Héliothermique de HUGLIN égal à 1.900 - approximatif pour la maturation du Cabernet-Sauvignon): la fraîcheur des nuits (FNv -r), la température moyenne de l?air (Tv-r), la température maximale de l?air (Txv-r) et l?amplitude thermique (Av-r). Les résultats montrent que IH est corrélé avec Tv-r (r=0,79**) et avec Txv-r (r=0,80**). IH représente donc bien les conditions thermiques générales de la période de maturation en ce qui concerne la température moyenne et maximale de l?air. Mais IH n?est pas corrélé ni avec Aa-s ni avec Av-r. Par contre, IF est corrélé avec Aa-s (r=-0,70**) et FNv-r est corrélé avec Av-r (r=-0,69**). Cette corrélation doit justifier, en partie, l?usage assez courant de l?amplitude thermique comme indicateur de bonnes conditions thermiques de maturation pour les régions qui présentent des valeurs élevées. Mais ce raisonnement peut amener à des caractérisations erronées. Le travail met en évidence, également, ?importance de considérer le bilan hydrique des régions (IS) dans l?analyse du régime thermique sur la qualité du raisin. On peut onclure que pour avoir une bonne caractérisation du régime thermique en période de maturation il faut considérer la fraîcheur des nuits (IF étant un bon indicateur de FNv-r moyen des régions, avec un r=0,80**), caractérisation qui peut être améliorée avec l?information des températures maximales et de sur 11l?amplitude thermique en période de maturation du raisin. Les éléments présentés peuvent servir à améliorer les indices climatiques pour estimer le potentiel qualitatif du raisin des différentes régions viticoles, notamment en complément de IF. ABSTRACT The thermal conditions during the grape ripening period are important variables related to colour of the grapes, anthocyanins, polyphenols and flavour of the wine. The main purpose of this work was to characterise the thermal conditions, especially the night coolness and the thermal amplitude during maturation, in the geoclimate of the world vine culture. A database of 100 grape-growing regions of 30 countries obtained from the World Meteorology Organisation (WMO) was used. Some climatic indexes were calculated: Cool Night Index ?IF (°C), Huglin?s Heliothermal Index ?IH (°C) and Dryness Index ?IS (mm), from the Multicriteria Climatic Classification System for World Viticulture, and the thermal amplitude in August and September Aa-s (°C). Over véraison-harvest period ?v-r(mean of the 30 days before harvesting date, estimated on the basis of HUGLIN Heliothermal Index equal to 1,900 ? approximately value to ripen Cabernet-Sauvignon) similar indexes were obtained: the cool night (FNv-r), the mean air temperature (Tv-r), the maximal air temperature (Txv-r) and the thermal amplitude (Av-r). The results showed that IH is positively correlated with Tv-r (r=0.79**), Txv-r (r=0.80)and IF (r=0.67**). Therefore, IH represents well the general thermal conditions during maturation period, specially concerning the mean and the maximal air temperature. owever, IH was correlated neither with Aa-s nor to Av-r. IF was negatively correlated with Aa-s (r= -0.70**) and FNv-r was negatively correlated with Av-r (r=-0.69**). The correlation to some extent explains the current use of the thermal amplitude to predict good ripening thermal conditions for those regions that show high values. As here we have described, this thinking may give incorrect results. This work has also showed the importance to consider the water balance of the regions (IS) in the effect of the thermal conditions in grape quality. We conclude that the characterisation of the thermal conditions during the ripening period do need the cool night index (in this case, IFis a good index to provide the mean FNv-r of the regions, r=0,80**). Factors other than cool night which influence this characterisation are both maximal air temperature and thermal amplitude data. The elements presented in this work, in addition to IF , may improve the climatic indexes to be used to predict the qualitative potential of grapes from different regions.

Zonage climatique viticole et cartographie numérique du Rio Grande do Sul - Brésil, par les indices du Système CCM Géoviticole.

Abstract: The State Rio Grande do Sul is the main producer of Brazilian fine wines, with four viticultural regions. The objective is the characterization of the viticultural climatic potential of the State (total surface of 281.749 km2). The methodology use the Géoviticulture Multicriteria Climatic Classification System (Géoviticulture MCC System), based on three climatic indices ? Dryness Index (DI), Heliotermal Index (HI) and Cool Night Index (CI). Based on latitude, longitude, altitude and distance from Atlantic Ocean, the 3 viticultural climatic indices were modeled and the algorithms applied to a DTM using GIS. The results show that Rio Grande do Sul has the following classes of viticultural climate: according to DI ? Moderately Dry, Sub-humid, Humid; according to HI ? Cool, Temperate, Temperate warm, Warm and Very Warm; according to CI ? Cool nights, Temperate nights, Warm nights. Based on the total surface, the most representatives viticultural climates are: « Humid x Temperate » (3,1%), « Humid x Temperate warm » (14,4%), « Humid x Warm » (52,6%), « Sub-humid x Warm » (20,0%) and « Sub-humid x Very warm » (5,8%). According to CI, the viticultural climates have a range of variation as a function of the interaction between « earlyness of the varieties x heliothermal availability ».

Azadirachtin on Oligonychus yothersi in yerba mate Ilex paraguariensis.

ABSTRACT The red mite Oligonychus yothersi is one of the main pests of yerba mate in Brazil The damage this mite causes leads to leaf drop and decreased production. There are no registered acaricides for use in yerba mate; thus, laboratory and field experiments were performed to evaluate the effect of azadirachtin (Azamax ® , 250mL 100L -1 ) for the control of the red mite in yerba mate. In the laboratory, azadirachtin was applied to yerba mate leaf disks before (residual contact) and after (direct contact) infestation with 15 newly emerged red mite adult females. The effect of azadirachtin on mite behavior was evaluated in arenas with treated and untreated yerba mate leaves, and the number of mites in both areas was recorded. Ovicidal action was evaluated by applying azadirachtin to eggs and recording egg hatching. In the field, two applications of the product were performed (1L spray liquid plant-1) with a 7-day interval. The numbers of living mites were evaluated at 7, 14 and 21 days following the first application on randomly collected leaves. It was observed 86.6 and 91.4% of mortality following 24h of residual and direct contact, respectively. Repellent (62% of individuals leaving the treated area) and ovicidal (98.9% decrease in egg hatching) effects were also observed. The mite population in the yerba mate crop field had decreased by 59.6% at 14 days after the first application of azadirachtin. The results show the potential of azadirachtin for the control of O. yothersi in yerba mate in Brazil.Key words: neem, alternative control, yerba mate pest. RESUMO O ácaro Oligonychus yothersi é uma das principais pragas da cultura da erva-mate. Seus danos levam à queda das folhas e redução da produção. Não há acaricidas registrados para uso na erva-mate e por isso foram realizados experimentos em laboratório e a campo para avaliar o efeito da azadiractina (Azamax®, 250mL 100L-1), visando ao controle da espécie na cultura da erva mate. Em laboratório, o produto foi aplicado em discos de folha de erva-mate antes (contato residual) e depois (contato direto) da infestação com 15 fêmeas adultas recém-emergidas do ácaro vermelho. A ação do produto no comportamento do ácaro foi avaliada em arenas com folhas de erva-mate tratadas e não tratadas, registrando-se o número de ácaros em ambas as áreas. Além disso, a ação ovicida foi avaliada, aplicando-se o produto sobre ovos e registrando a sua eclosão. No campo, foram realizadas duas aplicações do produto (1L de calda planta-1), espaçadas sete dias. Avaliou-se o número de ácaros vivos, aos 7, 14 e 21 dias após a primeira aplicação, em folhas coletadas aleatoriamente. Observou-se ação acaricida (86,6 e 91,4% de mortalidade após 24h, respectivamente, por contato residual e direto; repelência (62% dos indivíduos abandonando a área tratada) e ação ovicida (redução de 98,9% na eclosão). Na lavoura de erva-mate, a redução populacional do ácaro foi de 59.6% aos 14 dias após a primeira aplicação do produto. Os resultados demonstram o potencial de emprego da azadiractina para o controle de O. yothersi na cultura da erva-mate.Palavra-chave: nim, controle alternativo, praga da erva-mate.

Starch, growth, and development in cuttings of rootstock "Paulsen 1103" from plants infested with ground pearl.

ABSTRACT The ground pearl, Eurhizococcus brasiliensis, is considered an important pest of vineyards in southern Brazil, with affected plants exhibiting leaf chlorosis, reduction in vigor, fading, and death. This study evaluated the quality of hardwood cuttings produced from plants infected (I) and not infected (NI) by ground pearl. ?Paulsen 1103? (Vitis berlandieri × Vitis rupestris) plants were grown for 29 months in brick-built raised beds either infested or not infested by ground pearl; then, 12 one-year-old branches with a maximum of 12 buds each were cut from each plant, subdivided into three portions (4 buds cutting-1), and subjected to destructive and nondestructive testing. Destructive testing comprised determining fresh and dry weight, length, internode diameters, and percentage of starch. Nondestructive testing comprised assessing the potential for bud sprouting and shoot development. Each mother plant in the I and NI beds was considered a replicate, with a total of 360 cuttings per treatment. It was observed that cuttings from infected plants had significantly lower (P<0.05) internode diameter, length, and fresh and dry weight than those of the uninfected plants. The percentage of starch content of the cuttings did not differ significantly. All cuttings showed the same percentage (100%) of bud breaking and no changes in growth and development of seedlings regardless of source. Given these results, it was concluded that vines of ?Paulsen 1103? infested with ground pearl produce smaller cuttings than those of uninfected plants but with no reduction in bud break percentage or seedling development. Key words: Margarodidae, Vitaceae, insect?plant interaction, carbohydrates. RESUMO A pérola-da-terra, Eurhizococcus brasiliensis, tem sido considerada uma importante praga dos vinhedos no sul do Brasil, sendo que as plantas atacadas manifestam clorose foliar, redução no vigor, definhamento e morte. Este trabalho teve por objetivo avaliar a qualidade de estacas lenhosas produzidas a partir do contraste de videiras infestadas (I) e não infestadas (NI) por pérola-da-terra. Após 29 meses de cultivo em canteiros de alvenaria, em presença ou ausência de pérola-da-terra, cada planta da variedade ?Paulsen 1103? (Vitis berlandieri × Vitis rupestris) foi submetida à retirada de 12 ramos de ano, com no máximo 12 gemas cada, sendo subdivididos em três porções 4 gemas estaca-1) e submetidos a avaliações destrutivas e não destrutivas. As destrutivas consistiram em determinar massas fresca e seca, comprimento, diâmetro de entrenós e percentual de amido. As avaliações não estrutivas consistiram em testar o potencial de brotação e desenvolvimento das estacas. Cada planta matriz dos canteiros I e NI foi considerada uma repetição, totalizando 360 estacas por tratamento. As estacas das plantas infestadas tiveram uma redução (P<0,05), em relação às não infestadas, em diâmetro, comprimento e massas fresca e seca. Não houve contraste significativo do percentual de amido avaliado das estacas. Quanto à brotação, destaca-se que todas as estacas apresentaram o mesmo percentual (100%), independente da origem, sem alterações no desenvolvimento e crescimento das mudas. Diante desses resultados, salienta-se que videiras ?Paulsen 1103? infestadas por pérola-da-terra produzem estacas menores, porém não há comprometimento no percentual de brotação e desenvolvimento das mudas, quando comparadas com plantas não infestadas.

LA PRODUCCIÓN DE SIGNIFICADOS Y REPRESENTACIONES DEL ESPACIO POR LA GEOGRAFÍA ESCOLAR: POSIBILIDADES Y LIMITACIONES EN LOS MAPAS

ResumenPresentamos en este artículo una reflexión sobre la producción de los significados y representaciones del espacio geográfico, a partir de una discusión sobre educación escolar en el componente curricular, Geografía en la Educación Básica. Proponemos una interrogación acerca de su aporte en la construcción de las percepciones espaciales, desencadenando este pensar especialmente sobre el uso, las limitaciones y las posibilidades reveladas en los mapas. De ese modo, invitamos a un cuestionamiento sobre las formas de utilización de ese recurso, que exige elecciones codificadas, simplificadas y representadas según criterios de escalas, símbolos y proyecciones cartográficas.Discutimos cómo la Geografía escolar utiliza los mapas y cómo propone los significados y representaciones de ese lenguaje en imagen, en la medida que son configuraciones producidas y cuyos contenidos son escogidos. Argumentamos que la educación escolar responde en gran parte a las representaciones construidas por las personas. Por eso, el presente texto es un ejercicio relevante para los educadores en general, una invitación al análisis de la utilización de los lenguajes específicos de cada área del conocimiento. Fortalecemos, de esa manera, el debate sobre las producciones de las representaciones, esenciales en los movimientos de la vida cotidiana de las personas que pasan por la escuela proyectando un currículo más abierto.Palabras clave: Aprendizaje escolar, significados, representaciones, Geografía escolar, mapa.AbstractWe present in this article a reflection on the production of meanings and representations in the geographical space, from a discussion on school education in the curriculum component, Geography in Basic Education. We propose a question about its contribution to the construction of spatial perceptions, triggering an analysis particularly about the use, limitations and opportunities revealed in the maps.Thus, we invite for discussion ways of utilizing that resource which requires encoded choices, simplified and represented according to criteria of scale, symbols and map projections. We discuss how the Geography student uses the maps and how the student applies the meanings and representations of that picture language in the settings as they are produced and whose contents are chosen.We argue that education is greatly due to the representations constructed by people. Therefore, this text is an important exercise for educators in general, an invitation to the analysis of the use of specific languages for each area of knowledge. In this way, we strengthen the debate over the production of essential representations in the movements of the daily life of the people passing through the school by projecting a more open curriculum.Key words: Elementary education, meanings, representations, school geography, maps.

EVALUACIÓN DEL RIESGO ANTE INCENDIOS FORESTALES EN LA CUENCA DEL RÍO TEMPISQUE, COSTA RICA

Los incendios forestales constituyen problemas que ocasionan grandes daños ambientales sobre los ecosistemas, uno de los mayores impactos en el ambiente son los efectos sobre el cambio climático, situación que acentúa los problemas globales que atentan la vida sobre el planeta. Notoriamente, se reconoce que los incendios son un agente constante de cambios sobre los paisajes naturales y por tanto su estudio reviste importancia, ya que afectan de una manera notable la vegetación, la fauna, el suelo y aumentan el peligro de desertificación, lo que conlleva a los problemas socioeconómicos. Este artículo tiene por objetivo determinar el riesgo ante incendios forestales en la cuenca del Río Tempisque en Costa Rica, a partir de variables explicativas como la proximidad a carreteras, tipos de usos de la tierra, focos de incendios, insolación y altitud sobre el nivel de mar, modeladas con técnicas de Evaluación Multicriterio (ECM) en un Sistema de Información Geográfica (SIG).Dado que el concepto riesgo se refiere a una condición de probabilidad, en este artículo se recrea escenarios en donde podría tener lugar el fuego, los cuales se correlacionan con eventos que se han presentando en años anteriores. Se debe advertir que no se considera la variable viento como factor dispersor del fuego, ya que el objetivo es determinar lugares con condición favorable a incendio sin mediar los factores que contribuyen en su distribución.Palabras claves: incendio forestal, problema ambiental, riesgo, modelaje, sistemas de información geográfica y evaluación multicriterio.AbstractForest fires are problems that cause environmental damage to ecosystems. One of the biggest impacts is on the atmosphere and their effects on climatic change, a situation that exacerbates globalproblems perpetrated on planet life. Historically, fires are recognized as a constant agent of change Julio César Moraga Peralta Evaluación del riesgo ante incendios forestalesen la cuenca del río Tempisque, Costa Rica on the natural landscape. Therefore, fire studies are important because of the significant effect of fire on vegetation, fauna and soils and the increased danger of desertification, leading to socioeconomicproblems.This article has as its objective to determine the risk before forest fires on the Tempisque RiverBasin in Costa Rica from explanatory variables such as proximity to roads, types of land uses, fireoutbreaks, isolation and altitude above sea level, using Multicriteria Evaluation (NDE) modeling techniques in a Geographic Information System.As the term risk refers to a condition of probability, this article recreates scenarios where a fire could occur, which correlate with events that have occurred in previous years. It should be noted that the variable of wind is not considered as a fire-scattering factor since the objective of this study is to identify places with conditions already favorable to fires without a contributing factor in their distribution.Key words: forest fire, environmental problems, risk, geographical information system, multicriteria evaluation modeling, Tempisque River Basin, Costa Rica

ANÁLISIS DE TENDENCIAS HIDROCLIMÁTICAS DE DOS CUENCAS REPRESENTATIVAS DE ISLA DE PUERTO RICO

El agua junto a las variaciones climáticas, encabezan discursos políticos y científicos globales en los que resurgen los debates sobre los conflictos acerca de este recurso, la geopolítica del agua, la gestión, la contaminación y la polución. Ante este panorama el IPCC (Panel Intergubernamental del Cambio Climático), la Organización Mundial de Meteorología (OMM),el Programa de la Naciones Unidas para el Medio Ambiente (PNUMA) y distintas organizaciones medioambientales hanenfocado sus intereses científicos en estudios en los cuales se utilicen indicadores hidroclimáticos. En este contexto, este artículo analiza la evolución hidroclimática reciente en dos cuencas principales de la isla de Puerto Rico, utilizando como indicadores las temperaturas, las precipitaciones y los caudales de distintas estaciones de NOAA y el USGS. Inicialmente analizamos cada estación individualmente y luego se hizo un análisis conjunto de la cuenca. Con los resultados obtenidos,en ninguna de las cuencas se pudo establecer tendencias claras en cuanto a la precipitación total anual. Aunque algunas estaciones mostraron tendencias positivas y otras regresivas, ninguna alcanzó valores estadísticamente significativos que permita rechazar la hipótesis nula de no tendencia. Nuestro análisis indica también que en una cuenca la temperatura media anual mostró un ligero aumento, mientras que en la otra la temperatura manifestó descendió. Por otro lado, el volumen de agua anual que discurre por las cuencas ha disminuido en ambos ríos donde se pudo rechazar la hipótesis nula de no tendencia con el análisis de Mann-Kendall. No obstante, existen otros factores que no fueron objeto de estudio en este análisis y que tienen impactos sobre los recursos hídricos, así como los distintos mosaicos paisajísticos que componen una cuenca hidrográfica.Palabras Claves: recursos hídricos, tendencias hidroclimáticas, cambio climático.ABSTRACTToday, water resources and climatic oscillations dominate all political and scientific discourses where the principal debate is focused on water management, water pollution and the geopolitics of this resource. Against this background, the IPCC (Intergovernmental Panel for Climate Change), WMO(World Meteorology Organization), the United Nations Environmental Program (UNEP) and other environmental organizations have focused their scientific research on hydro-climatic evolution. In this context, this article examines recent developments in hydro-climatic evolution on two mainrivers in Puerto Rico, using temperature, rainfall, stream-flow and discharge data from NOAA climatic stations and USGS hydrological stations. Initially, we analyze data from each individual station and then make an integrated analysis of the basins. With the obtained results, in none of the basins was it possible to establish clear trends as to total annual precipitation. Though some stations showed positive trends and others regressive, none reached statistically significant values.Our analysis also indicates that in one basin the annual average temperature showed a slight increase, whereas in the other basin a temperature decrease was confirmed. On the other hand, the volume of annual discharge from both rivers showed a decrease. However, there are other factors that were not considered in this analysis, such as land use, that impact water resources and the various landscape mosaics comprising a watershed.Key Words: water resources, hydro-climatic evolution, climate change

DISEÑO DE UN GEOPORTAL PARA ANALIZAR LAS INICIATIVAS DE DESARROLLO RURAL LEADER EN EXTREMADURA

En Europa se están gestionando Políticas de Desarrollo Rural desde el año 1991 bajo el amparo de la Iniciativa LEADER. En este proyecto se ha diseñado un Geoportal para visualizar las Iniciativas LEADER de Desarrollo Rural en Extremadura. Para su elaboración se utilizó MapServer que facilita la introducción de las variables físicas, demográficas, económicas, equipamientos y las inversiones por medidas en una base de datos  cartográfica y alfanumérica a escala municipal. El diseño de dicho Geoportal permite, por una parte, analizar el impacto de este tipo de políticas en los últimos dieciséis años, así como establecer su contribución a la mejora de las condiciones de vida de la población rural, sin duda, objetivo principal de estas iniciativas. Y, por otra parte, facilita la consulta pública de los datos sin coste alguno para el usuario, al estar disponible en software SIG Libre.Palabras clave: Europa, LEADER Iniciativa, SIG, software libre, MapServer.ABSTRACTIn Europe, Rural Development Policy since 1991 has been managed under the auspices of the LEADER Initiative. In this project a Geoportal has been designed to visualize rural development under the LEADER Initiatives. MapServer has been used for elaboration and the physical, demographic, economic, equipment and investment measures have been introduced in an alphanumeric and cartographic database to municipal scale. The design of the Geoportal allows the impact of the policies over the last 16 years to be analyzed, as well as to determine their impact on improving the living conditions of the rural population, without a doubt the main objective of these initiatives. Moreover, it allows inspection of the data at no cost to the user via free Open Source GIS software.Key Words: Europe, LEADER Initiative, GIS, Open Source, MapServer.
