Spatial relationship between the atmospheric circulation and the precipitation measured in the western Swiss Alps by means of the analogue method

An adaptation technique based on the synoptic atmospheric circulation to forecast local precipitation, namely the analogue method, has been implemented for the western Swiss Alps. During the calibration procedure, relevance maps were established for the geopotential height data. These maps highlight the locations were the synoptic circulation was found of interest for the precipitation forecasting at two rain gauge stations (Binn and Les Marécottes) that are located both in the alpine Rhône catchment, at a distance of about 100 km from each other. These two stations are sensitive to different atmospheric circulations. We have observed that the most relevant data for the analogue method can be found where specific atmospheric circulation patterns appear concomitantly with heavy precipitation events. Those skilled regions are coherent with the atmospheric flows illustrated, for example, by means of the back trajectories of air masses. Indeed, the circulation recurrently diverges from the climatology during days with strong precipitation on the southern part of the alpine Rhône catchment. We have found that for over 152 days with precipitation amount above 50 mm at the Binn station, only 3 did not show a trajectory of a southerly flow, meaning that such a circulation was present for 98% of the events. Time evolution of the relevance maps confirms that the atmospheric circulation variables have significantly better forecasting skills close to the precipitation period, and that it seems pointless for the analogue method to consider circulation information days before a precipitation event as a primary predictor. Even though the occurrence of some critical circulation patterns leading to heavy precipitation events can be detected by precursors at remote locations and 1 week ahead (Grazzini, 2007; Martius et al., 2008), time extrapolation by the analogue method seems to be rather poor. This would suggest, in accordance with previous studies (Obled et al., 2002; Bontron and Obled, 2005), that time extrapolation should be done by the Global Circulation Model, which can process atmospheric variables that can be used by the adaptation method.

Introduction of snow and geomorphic disturbance variables into predictive models of alpine plant distribution in the Western Swiss Alps

Indirect topographic variables have been used successfully as surrogates for disturbance processes in plant species distribution models (SDM) in mountain environments. However, no SDM studies have directly tested the performance of disturbance variables. In this study, we developed two disturbance variables: a geomorphic index (GEO) and an index of snow redistribution by wind (SNOW). These were developed in order to assess how they improved both the fit and predictive power of presenceabsence SDM based on commonly used topoclimatic (TC) variables for 91 plants in the Western Swiss Alps. The individual contribution of the disturbance variables was compared to TC variables. Maps of models were prepared to spatially test the effect of disturbance variables. On average, disturbance variables significantly improved the fit but not the predictive power of the TC models and their individual contribution was weak (5.6% for GEO and 3.3% for SNOW). However their maximum individual contribution was important (24.7% and 20.7%). Finally, maps including disturbance variables (i) were significantly divergent from TC models in terms of predicted suitable surfaces and connectivity between potential habitats, and (ii) were interpreted as more ecologically relevant. Disturbance variables did not improve the transferability of models at the local scale in a complex mountain system, and the performance and contribution of these variables were highly species-specific. However, improved spatial projections and change in connectivity are important issues when preparing projections under climate change because the future range size of the species will determine the sensitivity to changing conditions.

Palaeotectonic and palaeogeographic evolution of the western Tethys and PeriTethyan domain (IGCP Project 369)

Project No. 369 (''Comparative Evolution of PeriTethyan Rift Basins'') of the International Geological Correlation Program produced a new palaeotectonic-palaeo-geographic atlas of the western PeriTethyan domain. The atlas contains more than two hundred new maps and documents grouped in nine regional sets (Iberia, Polish Trough, Eastern European and Scythian Platforms, Moesian Platform, Levant, Arabian Platform,, Northern Africa, NE Africa-NW Arabia, Libya-Pelagian Shelf plus a set of reconstructions for the whole western Tethys. The area, considered in the atlas stretches. from west to east, from the eastern Atlantic shores to the Urals and, from north to south, from the Baltic shield to equatorial Africa; the time span covered extends from the Late. Carboniferous to the Present. The dataset, resulting from an extensive cooperation between industrial and academic sources, is accessible interactively on a CD-ROM (Stampfli et al., 2001a) and includes legend, timetable, short explanatory notes, full references and additional supporting data. This dataset provides information on the development of the Tethyan realm in space and time. In particular, the relation between the Variscan and Cimmerian cycles in the Mediterranean realm is illustrated by numerous palaeogeographic and palaeotectonic maps.

Nachhaltige Energie für ländliche Entwicklung in dem Sub-Sahara Afrika: interdisziplinäre Herangehensweise und organisatorische Herausforderung

Angesichts der Geschichte der Entwicklungspolitik, ist diese Arbeit darauf ausgerichtet, einige Beobachtungen in Bezug auf die so genannte Entwicklung hervorzuheben; insbesondere auf die andauernde prekäre Situation und Armut in ländlichen afrikanischen Gebieten. Armut ist nach Amartya SEN – weiter präzisiert von J.L. Dubois – die Deprivation von „Fähigkeiten“, die Individuen und lokale Gemeinschaften zu ausgeschlossenen und vergessenen Akteuren des Systems machen. Das nennt Paulo Freire, das Menschen zu „Objekten“ gemacht werden. Es rechtfertigt die starke Annahme, die in dieser Studie getroffen wird, dass vielmehr die Menschen als „Subjekte“ ihrer Veränderung und Entwicklung im Mittelpunkt stehen. Die Arbeit zeigt und erklärt in historischer Chronologie, wie die Entwicklungspolitiken und unterschiedliche Beteiligte auf allen Ebenen diese Situation verursachen. Trotz alledem bleiben die Individuen und lokalen Gemeinschaften, die in Symbiose mit ihrer natürlichen Umwelt leben, die reich an verschiedenen Ressourcen und Potentialen ist, als Reaktion darauf und gleichzeitig als Überlebensstrategie zutiefst verbunden mit dem, was sie vor Ort haben, womit sie eine tiefere und intensive Beziehung besitzen, wenn man von ihrer Geschichte, ihrer Kultur und der Handlungslogik ausgeht. Für externe Akteure, die sie über das vorhandene System dominieren und beeinflussen bleiben sie „Objekte“, aber in der Vielzahl ihrer endogenen Initiativen, zeigen sie die Fähigkeit und Substanz, die beweisen, dass sie auf ihrer Ebene das eigentliche Subjekt sind, die dynamischen Akteure. Aber isolierte Initiativen auf spezifische reale Bedürfnisse bei gleichzeitiger Dominierung durch das System mit seiner Marktlogik, führt dies langfristig nur zu dem Zirkulus Vitiosus der Armut. Daher ist eine ganzheitliche Sicht entscheidend für nachhaltige Entwicklung und für die notwendige Veränderung. Es geht nicht nur um die Veränderung des Systems und die Wahl politischer Maßnahmen, sondern genau genommen um das Verhalten der Akteure auf allen Ebenen und die Art der Beziehungen zwischen ihnen allen. Es ist eine Frage des erneuten Überdenkens des Entwicklungspfades, der andere Logik, Visionen, Interessen und Strategien aller Beteiligten, unserer so genannten Akteure einschließt. Ob dies von endogenen Initiativen oder neuen gemeinsamen Projekten ausgeht: man wird in einen Prozess kollektiven Lernens eintreten, den Paul Singer und Clarita Müller-Plantenberg erläutern und entwickeln in dem Konzept der Inkubation und Solidarischen Ökonomie, die Eigeninitiative, Selbstbestimmung und Selbstverwaltung von lokalen Gemeinschaften und die Öffnung für eine Neu-Konzeptualisierung und Institutionalisierung einschließt. So ein Prozess ist nur mit einem interdisziplinären Rahmen möglich. Dieser Rahmen soll auf einer zusätzlicher Kommunikation zwischen den Akteuren und Sozialwissenschaften beruhen und mit jenen, die auf dem Feld der Technologie arbeiten. So können dann technische „Experten“ angesichts eines technischen Projektfehlers, der aufgrund von bestimmten sozialen und kulturellen Realitäten zustande kam sagen, „es ist kein Scheitern ; es war ein Schritt innerhalb eines Lernprozesse der in die technischen Projekte und Studien einbezogen werden muss“. Wir haben das Energiethema gewählt; und insbesondere, Energie für eine nachhaltige ländliche Entwicklung in Subsahara-Afrika, um den Weg von der Theorie in die Praxis zu illustrieren und experimentell auszuprobieren, den Weg von den Beobachtungen zu der Veränderung, wobei Fragen, Annahmen, Strategien und konkrete Aktionen für den Wandel behandelt werden. Wir nennen unseren experimentellen Weg: DRIEE, das heißt auf Deutsch Ländliche Entwicklung und Inkubation von Energieunternehmen. Dabei gehen wir davon aus, dass: - Energie im Allgemeinen auf der internationalen Ebene fast gleichbedeutend mit Elektrizität ist. Heute bestehen die wichtigsten Bedürfnisse nach Energie dort wo die agro-pastorale Produktion, das Kochen, die Nahrungsmittelkonservierung und Verarbeitung …etc. stattfindet. - Diese ländliche Bevölkerung zu etwa 80% der nationalen Wirtschaft ausmacht. Dass sie gleichzeitig aber nur zu weniger als 5% der Energieproduktion Zugang hat, was oft auf Licht reduziert ist und nicht einmal ihrer Produktion zugute kommen kann. - Die Projekte für Energie und Elektrizität vor allem auf die Technologischen Fragen konzentriert sind und weniger auf die Bedürfnisse. Fast die Gesamtheit der Fonds für Energie wird in Bezug auf die Investitionen Infrastruktur der Produktion und Verteilung durch die konventionellen zentralisierten Netze geplant. Angesichts dieser Analysen gehen die in dieser Arbeit vorgenommenen Studien in Gambia und Kamerun von Bestandsaufnahmen und / oder beschreibenden regionalen Analysen aus: - von Bedürfnissen, von Praktiken und lokalen Initiativen von Fragen der Energie, für einzelne Professionen, Haushalte, Gruppen, spezifische Gruppen, wie Frauen, ländliche Gemeinden mit ihren spezifischen Charakteristika. - Von Potentialen: natürliche lokale Energieressourcen, soziokulturelle Ressourcen – so z.B. die empirisch feststellbaren menschliche Ressourcen wie endogenes Wissen und praktische organisatorische Fähigkeiten gegenüber den Problemen der Energie. Dieser experimentelle Schritt von Handlungsforschung (DRIEE) in Kamerun führte zu der Gründung einer Organisation, über die und mit der wir die Logik der Inkubation und Solidarischen Ökonomie einführen. Das ist FERDEDSI, das heißt auf Deutsch „Forum für Erneuerbare Energie – Nachhaltige Entwicklung und Internationale Solidarität“. Zunächst war dies eine Energiegenossenschaft und dann (im Prozess) wurde es zu einer institutionellen Nische von mehreren Mikro Initiativen in ländlichen Gebieten. FERDEDSI ist ein Prozess der Inkubation und ein Inkubator ist also gleichzeitig ein inkubiertes Energieunternehmen aber auch ein Inkubator für lokale Organisationen. Die ersten Aktionen finden in den Departments von Noun und Ménoua in der westlichen Provinz von Kamerun statt. Während der Forschungsperiode findet akademische Austausch statt (Nord-Süd und Süd-Süd), diese ist dabei zu formalen Partnerschaften zu werden, nicht nur zwischen Universitäten sondern genauer lokale Organisationen und Universitäten. Dieser letzte Typ von Partnerschaften, die die solidarische Ökonomie ausmachen ist auch eine Innovation des Prozesses für die afrikanischen Fälle, die dem Beispiel dessen, was in Lateinamerika geschieht, folgen. So kommt es zu gegenseitiger sinnvoller Ausbildung in den internationalen Arbeitsgruppen und Seminaren der Universität.

The MaPS project: mapping teacher conceptions of musical development

The chapter starts from the premise that an historically- and institutionally-formed orientation to music education at primary level in European countries privileges a nineteenth century Western European music aesthetic, with its focus on formal characteristics such as melody and rhythm. While there is a move towards a multi-faceted understanding of musical ability, a discrete intelligence and willingness to accept musical styles or 'open-earedness', there remains a paucity of documented evidence of this in research at primary school level. To date there has been no study undertaken which has the potential to provide policy makers and practitioners with insights into the degree of homogeneity or universality in conceptions of musical ability within this educational sector. Against this background, a study was set up to explore the following research questions: 1. What conceptions of musical ability do primary teachers hold a) of themselves and; b) of their pupils? 2. To what extent are these conceptions informed by Western classical practices? A mixed methods approach was used which included survey questionnaire and semi-structured interview. Questionnaires have been sent to all classroom teachers in a random sample of primary schools in the South East of England. This was followed up with a series of semi-structured interviews with a sub-sample of respondents. The main ideas are concerned with the attitudes, beliefs and working theories held by teachers in contemporary primary school settings. By mapping the extent to which a knowledge base for teaching can be resistant to change in schools, we can problematise primary schools as sites for diversity and migration of cultural ideas. Alongside this, we can use the findings from the study undertaken in an English context as a starting point for further investigation into conceptions of music, musical ability and assessment held by practitioners in a variety of primary school contexts elsewhere in Europe; our emphasis here will be on the development of shared understanding in terms of policies and practices in music education. Within this broader framework, our study can have a significant impact internationally, with potential to inform future policy making, curriculum planning and practice.

Mid-Holocene and glacial-maximum vegetation geography of the northern continents and Africa.

BIOME 6000 is an international project to map vegetation globally at mid-Holocene (6000 14C yr bp) and last glacial maximum (LGM, 18,000 14C yr bp), with a view to evaluating coupled climate-biosphere model results. Primary palaeoecological data are assigned to biomes using an explicit algorithm based on plant functional types. This paper introduces the second Special Feature on BIOME 6000. Site-based global biome maps are shown with data from North America, Eurasia (except South and Southeast Asia) and Africa at both time periods. A map based on surface samples shows the method’s skill in reconstructing present-day biomes. Cold and dry conditions at LGM favoured extensive tundra and steppe. These biomes intergraded in northern Eurasia. Northern hemisphere forest biomes were displaced southward. Boreal evergreen forests (taiga) and temperate deciduous forests were fragmented, while European and East Asian steppes were greatly extended. Tropical moist forests (i.e. tropical rain forest and tropical seasonal forest) in Africa were reduced. In south-western North America, desert and steppe were replaced by open conifer woodland, opposite to the general arid trend but consistent with modelled southward displacement of the jet stream. The Arctic forest limit was shifted slighly north at 6000 14C yr bp in some sectors, but not in all. Northern temperate forest zones were generally shifted greater distances north. Warmer winters as well as summers in several regions are required to explain these shifts. Temperate deciduous forests in Europe were greatly extended, into the Mediterranean region as well as to the north. Steppe encroached on forest biomes in interior North America, but not in central Asia. Enhanced monsoons extended forest biomes in China inland and Sahelian vegetation into the Sahara while the African tropical rain forest was also reduced, consistent with a modelled northward shift of the ITCZ and a more seasonal climate in the equatorial zone. Palaeobiome maps show the outcome of separate, independent migrations of plant taxa in response to climate change. The average composition of biomes at LGM was often markedly different from today. Refugia for the temperate deciduous and tropical rain forest biomes may have existed offshore at LGM, but their characteristic taxa also persisted as components of other biomes. Examples include temperate deciduous trees that survived in cool mixed forest in eastern Europe, and tropical evergreen trees that survived in tropical seasonal forest in Africa. The sequence of biome shifts during a glacial-interglacial cycle may help account for some disjunct distributions of plant taxa. For example, the now-arid Saharan mountains may have linked Mediterranean and African tropical montane floras during enhanced monsoon regimes. Major changes in physical land-surface conditions, shown by the palaeobiome data, have implications for the global climate. The data can be used directly to evaluate the output of coupled atmosphere-biosphere models. The data could also be objectively generalized to yield realistic gridded land-surface maps, for use in sensitivity experiments with atmospheric models. Recent analyses of vegetation-climate feedbacks have focused on the hypothesized positive feedback effects of climate-induced vegetation changes in the Sahara/Sahel region and the Arctic during the mid-Holocene. However, a far wider spectrum of interactions potentially exists and could be investigated, using these data, both for 6000 14C yr bp and for the LGM.

Geological map of the Scalaro Valley – Sesia Zone (Italian Western Alps)

In the Sesia Zone (Italian Western Alps), slivers of continental crust characterised by an Alpine high-pressure imprint are intermingled with abundant mafic rocks and Mesozoic metasediments. An extensive study of the central Sesia Zone was undertaken to identify and reconstruct the lithological setting of the mono-cyclic sediments of the Scalaro Unit. A new geological map (1:5000) and schematic cross sections across the Scalaro Unit and the adjoining Eclogitic Micaschist Complex are presented here. In order to delimit the size and shape of the mono-metamorphic unit and understand its internal geometry with respect to the poly-metamorphic basement, an integrated approach was used. Linking observations and data across a range of scales, from kilometres in the field down to petrological and chronological data obtained at micrometre scale, we define for the first time the real size and internal geometry of the Scalaro Unit, as well as its large-scale structural context.

Land cover layer, digitized from the PEF Survey of Western Palestine (1880)

Geographic information systems allow the extraction and quantitative analysis of information from historical maps. The aims of this research were to examine the completeness of information represented on the 1881 Palestine Exploration Fund (PEF) map, to quantitatively reconstruct the landscape of nineteenth century Palestine and to explore whether spatial patterns in land cover/land use can be partially explained statistically by physical and human factors. Using historical aerial photos, we concluded that most of the major past landscape features were indeed shown on the PEF map, with an average overall correspondence of 53%. Forests and Mediterranean maquis were more abundant at distances greater than 2 km from towns and villages. Specific land cover/land-use types were associated with certain soil types, topographic regions and rainfall thresholds. In conclusion, the 1881 PEF map can serve as a reliable reference for understanding the land cover/land-use patterns of nineteenth century Palestine.
