Organic Farming as a Compensatory Measure German's agricultural land is not only being gobbled up by development; whole sections are being bought up in compensation for interventions made elsewhere, thus rapidly decimating the countrie's farming land resources. For this reason, calls are being made to take land that is converted from conventional to organic farming and add it to the pool of "compensation" areas, thus killing two birds - one of them being the establishment of more organic farming - with one stone. Various German regions have adopted the approach. Although organic farming serves both agricultural and environmental objectives, it cannot cover all the requirements of nature conservation. For example, it benefits abiotic resources such as soil and water through its use of natural fertilizers and erosion-combating cultivation, but can do little to protect highly endangered species and biotopes. Moreover, organic farms do not necessarily meet the legal requirement that compensation land must fulfil a similar function to the land it is "compensating" for. In other words, land converted to organic farming cannot necessarily ameliorate or compensate for impact on biotopes and species elsewhere. Regarding this approach as a solution to the rapid disappearance of farming land simply diverts attnetion away from the real cause: Urban sprawl and road building.

Im Rieselfeldgebiet Berlin-Süd verursachte die Abwasserbeaufschlagung Veränderungen in der Struktur des Geosystems und in seinen Interaktionen mit der Umgebung. Bei der Einstellung des Abwasserinputs unterliegt das Bodensubstrat einer intensiven Nettomineralisierung, einer Zunahme der Acidität sowie Abnahme der Pufferkapazität. Sowohl der Ap- und der Al-Horizont als auch die beiden Unterbodenhorizonte Bts bzw. Cv wiesen charakteristische Veränderungen der Schwermetallgehalte, der organischen Bodensubstanz sowie der Kationenaustauschkapazität auf. Die Sickerwasserproben zeigten generell eine Zunahme der Acidität und der Konzentration biophiler Stoffspecies bzw. von Schwermetallen, wobei in allen Untersuchungsebenen eine gleichsinnige Beschaffenheitsänderung erfolgte.

Extreme Regenereignisse von kurzer Dauer im Bereich von Stunden und darunter rücken aufgrund der dadurch bedingten Schäden durch Sturzfluten und auch wegen ihrer möglichen Intensivierungen durch den anthropogenen Klimawandel immer stärker in den Fokus. Die vorliegende Studie untersucht auf Basis von teilweise sehr langen (> 50 Jahre) und zeitlich hochaufgelösten Zeitreihen (≤ 15 Minuten) mögliche Trends in Starkregenintensitäten für Stationen aus schweizerischen und österreichischen Alpenregionen sowie für das Emscher-Lippe-Gebiet in Nordrhein-Westfalen. Es wird deutlich, dass es eine Zunahme der extremen Niederschlagsintensitäten gibt, welche gut durch die Erwärmung des regionalen Klimas erklärt werden kann: Die Analysen langfristiger Trends der Überschreitungssummen und Wiederkehrniveaus zeigen zwar erhebliche Unsicherheiten, lassen jedoch eine Zunahme in einer Größenordnung von 30 % pro Jahrhundert erkennen. Zudem wird in diesem Beitrag, basierend auf einer "mittleren" Klimasimulation für das 21. Jahrhundert, für ausgewählte Stationen der Emscher-Lippe-Region eine Projektion für extreme Niederschlagsintensitäten in sehr hoher zeitlicher Auflösung beschrieben. Dabei wird ein gekoppeltes räumliches und zeitliches "Downscaling" angewendet, dessen entscheidende Neuerung die Berücksichtigung der Abhängigkeit der lokalen Regenintensität von der Lufttemperatur ist. Dieses Verfahren beinhaltet zwei Schritte: Zuerst werden großräumige Klimafelder in täglicher Auflösung durch Regression mit den Temperatur- und Niederschlagswerten der Stationen statistisch verbunden (räumliches Downscaling). Im zweiten Schritt werden dann diese Stationswerte mithilfe eines sogenannten multiplikativen stochastischen Kaskadenmodells (MC) auf eine zeitliche Auflösung von 10 Minuten disaggregiert (zeitliches Downscaling). Die neuartige, temperatursensitive Variante berücksichtigt zusätzlich die Lufttemperatur als erklärende Variable für die Niederschlagsintensitäten. Dadurch wird der mit einer Erwärmung zu erwartende höhere atmosphärische Feuchtegehalt, welcher sich aus der Clausius-Clapeyron-Beziehung (CC) ergibt, mit in das zeitliche Downscaling einbezogen.
Für die statistische Auswertung der extremen kurzfristigen Niederschläge wurden die oberen Quantile (99,9 %), Überschreitungssummen (ÜS, P > 5 mm) und 3-jährliche Wiederkehrniveaus (WN) einer Dauerstufe von ≤ 15-Minuten betrachtet. Diese Auswahl erlaubt die gleichzeitige Analyse sowohl von Extremwertstatistiken als auch von deren langfristigen Trends; leichte Abweichungen von dieser Wahl beeinflussen die Hauptergebnisse nur unwesentlich. Nur durch die Hinzunahme der Temperatur wird die beobachtete Temperaturabhängigkeit der extremen Quantile (CC-Scaling) gut wiedergegeben. Bei Vergleich von Beobachtungsdaten und Gegenwartssimulationen der Modellkaskade zeigt das temperatursensitive Verfahren konsistente Ergebnisse. Im Vergleich zu den Entwicklungen der letzten Jahrzehnte werden für die Zukunft ähnliche oder sogar noch stärkere Anstiege der extremen Niederschlagsintensitäten projiziert. Dies ist insofern bemerkenswert, als diese anscheinend hauptsächlich durch die örtliche Temperatur bestimmt werden, denn die projizierten Trends der Niederschlags-Tageswerte sind für diese Region vernachlässigbar.
Die Stellung der Landwirtschaft im Naturschutzrecht besitzt für das Verhältnis von Naturschutz und Landwirtschaft eine zentrale Bedeutung. Obwohl von der Landwirtschaft als dem größten Flächennutzer erhebliche Umweltbelastungen ausgehen, ist sie durch eine Vielzahl von Ausnahmeregelungen von zentralen Instrumenten des Naturschutzes wie der Eingriffsregelung ausgenommen und gegenüber anderen Nutzungen privilegiert. Hinzu kommen unterschiedliche Anforderungen in den Ländern. Bei der Weiterentwicklung des Naturschutzrechts stehen die Anforderungen des Naturschutzes an die Landwirtschaft regelmäßig im Mittelpunkt der politischen Auseinandersetzung. Vor dem Hintergrund der aktuellen Krise in der Landwirtschaft wird das rechtliche Verhältnis von Landwirtschaft und Naturschutz analysiert und Möglichkeiten für eine Weiterentwicklung aufgezeigt.

Phytoplankton biomass and production regulates key aspects of freshwater ecosystems yet its variability and subsequent predictability is poorly understood. We estimated within-lake variation in biomass using high-frequency chlorophyll fluorescence data from 18 globally distributed lakes. We tested how variation in fluorescence at monthly, daily, and hourly scales was related to high-frequency variability of wind, water temperature, and radiation within lakes as well as productivity and physical attributes among lakes. Within lakes, monthly variation dominated, but combined daily and hourly variation were equivalent to that expressed monthly. Among lakes, biomass variability increased with trophic status while, within-lake biomass variation increased with increasing variability in wind speed. Our results highlight the benefits of high-frequency chlorophyll monitoring and suggest that predicted changes associated with climate, as well as ongoing cultural eutrophication, are likely to substantially increase the temporal variability of algal biomass and thus the predictability of the services it provides.
Der Beitrag zeigt auf, dass sich mit "Wildnis" und Planung Paradoxien in mehrfacher Hinsicht verbinden: So ist in Mitteleuropa die Grenzziehung zwischen anthropogener Nutzung und ungelenkter Entwicklung immer eine bewusst zu treffende Entscheidung - alle unsere Nationalparke und Kernzonen anderer Schutzgebiete beruhen auf diesem Prinzip. Vor dem Hintergrund des umfassenden Gestaltungsanspruchs einer "Landschafts-"Planung gilt es zudem zu beachten, dass umfassende Eingriffe in komplexe Systeme gerade keine Rückkoppelung mehr zulassen, welche Folgen genau auf welche Einzelmaßnahmen zurückzuführen sind und damit in eine "geplante PLanlosigkeit" münden. In Mitteleuropa wird Wildnis großflächig in der Regel nur als Folge einer bewussten Entscheidung möglich sein, jedoch wird daneben immer auch das Prinzip Zufall als wesentlicher Gestalter stehen. Anlass, sich mit dem Thema Wildnis und Planung zu befassen, geben auch Flächenansprüche nach Räumen ungelenkter Entwicklung, die den vorläufigen Stand einer Entwicklung des Naturschutzgedankens markieren, dabei aber in der flächendeckend von menschlicher Einflussnahme geprägten mitteleuropäischen Kulturlandschaft oft im Konflikt zu Nutzungsinteressen stehen. Daneben zeichnet sich unter den Bedingungen des Weltmarktes und der EU-Osterweiterung ein Rückzug der Landwirtschft aus der Fläche ab, der neue Spielräume eröffnet, zugleich aber die Frage nach Lenkungsmöglichkeiten aufwirft. Der bewusste Umgang mit Wildnis im Siedlungsraum beinhaltet dabei mehrere Dimensionen: Eine räumliche (z.B. Zonierungen oder die Lage von Schutzgebieten betreffend), eine zeitliche (z.B. das Zulassen temporären Verwilderns), die Rolle des Menschen (z.B. die Art eines reglementierten/unregelmentierten Zugangs zu den betreffenden Gebieten) und die Art der Vermittlung des Wildnisgedankens (kommen unterstützend pädagogische Hilfsmittel zum Einsatz oder wird ganz bewusst davon abgesehen?). "Planung und Wildnis" bedeutet dabei, sich gerade auch über letzteres, nämlich die Kommunikation und Vermittlung von Naturschutzzielen im klaren zu sein.
Wildfires, as a key disturbance in forest ecosystems, are shaping the world's boreal landscapes. Changes in fire regimes are closely linked to a wide array of environmental factors, such as vegetation composition, climate change, and human activity. Arctic and boreal regions and, in particular, Siberian boreal forests are experiencing rising air and ground temperatures with the subsequent degradation of permafrost soils leading to shifts in tree cover and species composition. Compared to the boreal zones of North America or Europe, little is known about how such environmental changes might influence long-term fire regimes in Russia. The larch-dominated eastern Siberian deciduous boreal forests differ markedly from the composition of other boreal forests, yet data about past fire regimes remain sparse. Here, we present a high-resolution macroscopic charcoal record from lacustrine sediments of Lake Khamra (southwest Yakutia, Siberia) spanning the last ca. 2200 years, including information about charcoal particle sizes and morphotypes. Our results reveal a phase of increased charcoal accumulation between 600 and 900 CE, indicative of relatively high amounts of burnt biomass and high fire frequencies. This is followed by an almost 900-year-long period of low charcoal accumulation without significant peaks likely corresponding to cooler climate conditions. After 1750 CE fire frequencies and the relative amount of biomass burnt start to increase again, coinciding with a warming climate and increased anthropogenic land development after Russian colonization. In the 20th century, total charcoal accumulation decreases again to very low levels despite higher fire frequency, potentially reflecting a change in fire management strategies and/or a shift of the fire regime towards more frequent but smaller fires. A similar pattern for different charcoal morphotypes and comparison to a pollen and non-pollen palynomorph (NPP) record from the same sediment core indicate that broad-scale changes in vegetation composition were probably not a major driver of recorded fire regime changes. Instead, the fire regime of the last two millennia at Lake Khamra seems to be controlled mainly by a combination of short-term climate variability and anthropogenic fire ignition and suppression.
The efficiency of sediment routing from land to the ocean depends on the position of submarine canyon heads with regard to terrestrial sediment sources. We aim to identify the main controls on whether a submarine canyon head remains connected to terrestrial sediment input during Holocene sea-level rise. Globally, we identified 798 canyon heads that are currently located at the 120m-depth contour (the Last Glacial Maximum shoreline) and 183 canyon heads that are connected to the shore (within a distance of 6 km) during the present-day highstand. Regional hotspots of shore-connected canyons are the Mediterranean active margin and the Pacific coast of Central and South America. We used 34 terrestrial and marine predictor variables to predict shore-connected canyon occurrence using Bayesian regression. Our analysis shows that steep and narrow shelves facilitate canyon-head connectivity to the shore. Moreover, shore-connected canyons occur preferentially along active margins characterized by resistant bedrock and high river-water discharge.
The number of people exposed to natural hazards has grown steadily over recent decades, mainly due to increasing exposure in hazard-prone areas. In the future, climate change could further enhance this trend. Still, empirical and comprehensive insights into individual recovery from natural hazards are largely lacking, hampering efforts to increase societal resilience. Drawing from a sample of 710 residents affected by flooding across Germany in June 2013, we empirically explore a wide range of variables possibly influencing self-reported recovery, including flood-event characteristics, the circumstances of the recovery process, socio-economic characteristics, and psychological factors, using multivariate statistics. We found that the amount of damage and other flood-event characteristics such as inundation depth are less important than socio-economic characteristics (e.g., sex or health status) and psychological factors (e.g., risk aversion and emotions). Our results indicate that uniform recovery efforts focusing on areas that were the most affected in terms of physical damage are insufficient to account for the heterogeneity in individual recovery results. To increase societal resilience, aid and recovery efforts should better address the long-term psychological effects of floods.
Why Reality overtakes Planning - Landscape Planning in the Light of System Theory and Functional Control. There is not only a common reality but different perspectives of reality and any perception is provisional and revisable. This opinion is a component of different approaches in science theory and perception theory. There are effects on ecological planning in various respects. They concern for example the comprehension of methods, the prognosis of complex systems and the part the landscape planner plays in this process. Concerning this attitude, methods as well as planning methods develop to means. Not to means of identification of true or false perception but to means of establishing deductive communication. Reality - also that of landscapes - changes steadily. Due to this creatures as well as their environment find themselves in a complex network process of adaption which is called co-evolution. This process can be seen in various changes in land use history. Accidental influences, for example the sudden application of an innovation, may have an unpredictable impact on the development of landscapes. How can the planner deal with changes caused by accidental processes? The category of compensation measures (bases on the regulation of impacts) in the German planning system is a good example for this. These aspects plead against an extensive meaning of the term "landscape"-planning, because this would lead the subject ad absurdum. Planning as an unalterable component of human being can efficiently only change parts of our natural surroundings. It cannot control the complexity of landscape, but must explain the interaction of its components.

Die ländlich peripheren Räume Ostdeutschlands gelten vielfach pauschal als schwer zu behandelnder regionaler "Sanierungsfall", dem aber im Vergleich zu den gravierenden Problemen von Bevölkerungsrückgang und Wohnungsleerstand in den Städten weniger Aufmerksamkeit gewidmet werden kann. Fragen nach Umfang und Beweggründen für die Zuwanderung älterer Menschen in diese Räume werden in diesem Zusammenhang ebenso als marginal betrachtet. Trotz der generellen Debatte zum demographischen Wandel wird vielfach noch nicht anerkannt, dass der Ruhestand keine "Restzeit" mehr ist, sondern ein eigener Lebensabschnitt von erheblicher Dauer für einen größer werdenden Teil der Bevölkerung, bei dem die Älteren sehr aktive Phasen durchleben. Der Beitrag stellt Ergebnisse einer Befragung von älteren Zugewanderten in den peripheren Regionen Brandenburgs vor. Auf dieser Grundlage werden Überlegungen zum "Potenzial" dieser älteren Menschen in Bezug auf die regionale Entwicklung und zu Konsequenzen für die räumliche Planung dargestellt.
Jährlich werden in Brandenburg ca. 500 ha Wald in andere Nutzungsarten umgewandelt. Durch die forst- und naturschutzrechtliche Pflicht zur Kompensation können die vielfältigen Funktionen des Waldes für Erholung, Natur- und Ressourcenschutz erhalten und gestärkt werden. Dafür ist eine intensive Zusammenarbeit von Forst- und Naturschutzverwaltung notwendig. So das Ergebnis einer Fachtagung des Lehrstuhl für Landschaftsplanung der Universität Potsdam am 10. Juni 2002 an der Landeslehrstätte für Naturschutz und Landschaftspflege in Lebus.

Planung ist untrennbar mit Annahmen über die Zukunft verbunden. Dabei lässt sich nachweisen, dass ein streng wissenschaftlich bzw. kausal eingegrenztes Prognoseverständnis für Prognosen in der Planung nicht zielführend ist. Für sie wird daher eine Auffassung entwickelt, die zum einen auf Ergebnisse der Chaosforschung, Systemtheorie und Thermodynamik, zum anderen auf in der Sozial- und Wirtschaftprognostik gebrauchte semantische (Wort-)Modelle Bezug nimmt: Aus ersteren ergibt sich, dass Prognosen komplexer Systeme keinesfalls mit Vorhersagen gleichgesetzt werden dürfen, sondern vielmehr eine rationale Analyse von Handlungsmöglichkeiten zu leisten haben. Aus letzteren wird deutlich, dass Prognosen als Mittel der Strukturierung von Informationen und damit letztlich zur Erkenntnisgewinnung eingesetzt werden können. Darauf aufbauend werden Anforderungen an doe Struktur von Prognosen und die Absicherung prognostisch relevanter Zusammenhänge aufgezeigt sowie Wirkfaktor- Beeinträchtigungsketten und Szenarien als gängige Prognosemethoden gegenübergestellt. Für die Kontrolle von Prognosen wird deutlich, dass einem Aufdekcne zugrunde gelegter wertender Annahmen und Randbedingungen u.U. größere Bedeutung als den eigentlichen Prognoseergebnissen zukommen kann.

Relationships between climate, species composition, and species richness are of particular importance for understanding how boreal ecosystems will respond to ongoing climate change. This study aims to reconstruct changes in terrestrial vegetation composition and taxa richness during the glacial Late Pleistocene and the interglacial Holocene in the sparsely studied southeastern Yakutia (Siberia) by using pollen and sedimentary ancient DNA (sedaDNA) records. Pollen and sedaDNA metabarcoding data using the trnL g and h markers were obtained from a sediment core from Lake Bolshoe Toko. Both proxies were used to reconstruct the vegetation composition, while metabarcoding data were also used to investigate changes in plant taxa richness. The combination of pollen and sedaDNA approaches allows a robust estimation of regional and local past terrestrial vegetation composition around Bolshoe Toko during the last similar to 35,000 years. Both proxies suggest that during the Late Pleistocene, southeastern Siberia was covered by open steppe-tundra dominated by graminoids and forbs with patches of shrubs, confirming that steppe-tundra extended far south in Siberia. Both proxies show disturbance at the transition between the Late Pleistocene and the Holocene suggesting a period with scarce vegetation, changes in the hydrochemical conditions in the lake, and in sedimentation rates. Both proxies document drastic changes in vegetation composition in the early Holocene with an increased number of trees and shrubs and the appearance of new tree taxa in the lake's vicinity. The sedaDNA method suggests that the Late Pleistocene steppe-tundra vegetation supported a higher number of terrestrial plant taxa than the forested Holocene. This could be explained, for example, by the "keystone herbivore" hypothesis, which suggests that Late Pleistocene megaherbivores were able to maintain a high plant diversity. This is discussed in the light of the data with the broadly accepted species-area hypothesis as steppe-tundra covered such an extensive area during the Late Pleistocene.
We present a pollen record for last 28 cal kyr BP from the eastern basin of Lake Karakul, the largest lake in Tajikistan, located in the eastern Pamir Mountains at 3915 m asl, a geographically complex region. The pollen record is dominated by Artemisia and Chenopodiaceae, while other taxa, apart from Poaceae, are present in low quantities and rarely exceed 5% in total. Arboreal pollen occur predominantly from similar to 28 to similar to 13 cal kyr BP, but as likely no trees occurred in the high mountain regions of the eastern Pamir during this time due to the high altitude and cold climate, arboreal taxa are attributed to long distance transport, probably by the Westerlies, the dominant atmospheric circulation. Tree pollen influx decreases strongly after similar to 13 cal kyr BP, allowing the pollen spectra to be interpreted as a regional vegetation signal. We infer that from 27.6 to 19.4 cal kyr BP the eastern Pamir was dominated by dry mountain steppe with low vegetation cover, while from 19.0 to 13.6 cal kyr BP Artemisia values increase and Chenopodiaceae, most herb taxa, and inferred far distant input from arboreal taxa decrease. Between 12.9 and 6.7 cal kyr BP open steppe vegetation dominated with maximum values in Ephedra, and while steppe taxa still dominated the spectra from 5.4 to 1 cal kyr BP, meadow taxa start to increase. During the last millennium, alpine steppe and alpine meadows expanded and a weak human influence can be ascertained from the increase of Asteraceae and the occurrence of Plantago pollen in the spectra.
The nature of the interaction between prehistoric humans and their environment, especially the vegetation, has long been of interest. The Qinghai Lake Basin in North China is well-suited to exploring the interactions between prehistoric humans and vegetation in the Tibetan Plateau, because of the comparatively dense distribution of archaeological sites and the ecologically fragile environment. Previous pollen studies of Qinghai Lake have enabled a detailed reconstruction of the regional vegetation, but they have provided relatively little information on vegetation change within the Qinghai Lake watershed. To address the issue we conducted a pollen-based vegetation reconstruction for an archaeological site (YWY), located on the southern shore of Qinghai Lake. We used high temporal-resolution pollen records from the YWY site and from Qinghai Lake, spanning the interval since the last deglaciation (15.3 kyr BP to the present) to quantitatively reconstruct changes in the local and regional vegetation using Landscape Reconstruction Algorithm models. The results show that, since the late glacial, spruce forest grew at high altitudes in the surrounding mountains, while the lakeshore environment was occupied mainly by shrub-steppe. From the lateglacial to the middle Holocene, coniferous woodland began to expand downslope and reached the YWY site at 7.1 kyr BP. The living environment of the local small groups of Paleolithic-Epipaleolithic humans (during 15.3-13.1 kyr BP and 9-6.4 kyr BP) changed from shrub-steppe to coniferous forest-steppe. The pollen record shows no evidence of pronounced changes in the vegetation community corresponding to human activity. However, based on a comparison of the local and regional vegetation reconstructions, low values of biodiversity and a significant increase in two indicators of vegetation degradation, Chenopodiaceae and Rosaceae, suggest that prehistoric hunters-gatherers likely disturbed the local vegetation during 9.0-6.4 kyr BP. Our findings are a preliminary attempt to study human-environment interactions at Paleolithic-Epipaleolithic sites in the region, and they contribute to ongoing environmental archaeology research in the Tibetan Plateau.
The climate conditions during Marine Isotope Stage (MIS) 3 were similar to present-day conditions, but whether humidity then exceeded present levels is debated, and the driving mechanisms of palaeoclimate evolution since MIS 3 remain unclear. Here, we use pollen data from Wulagai Lake, Inner Mongolia, to reconstruct vegetation and climate changes since the middle MIS 3. The steppe biome is reconstructed as the first dominant biome and the desert biome as the second, and the results show that the vegetation was steppe over the last 43,800 years. Poaceae, Artemisia, Caryophyllaceae and Humulus were abundant from middle to late MIS 3, indicating humid climate conditions. As drought-tolerant species such as Hippophae, Nitraria and Chenopodiaceae spread during MIS 2, the climate became arid. The Holocene is characterized by the dominance of steppe with mixed coniferous-broadleaved forests in the Greater Hinggan Range, and the desert biome retains high affinity scores, indicating that the climate was semi-arid. The climate from middle to late MIS 3 was wetter than in the Holocene; this shift was related to changes in the Northern Hemisphere's solar insolation and ice volume. The humid conditions during MIS 3 were attributed to strong ice–albedo feedback, which led to evaporation that was less than the precipitation. The enhanced evaporation caused by increased solar insolation and decreased ice volume might have exceeded the precipitation during the Holocene and resulted in low effective humidity in the Wulagai Lake basin.
To fulfill the 2030 Agenda, the complexity of sustainable development goal (SDG) interactions needs to be disentangled. However, this understanding is currently limited. We conduct a cross-sectional correlational analysis for 2016 to understand SDG interactions under the entire development spectrum. We apply several correlation methods to classify the interaction as synergy or trade-off and characterize them according to their monotony and linearity. Simultaneously, we analyze SDG interactions considering population, location, income, and regional groups. Our findings highlight that synergies always outweigh trade-offs and linear outweigh non-linear interactions. SDG 1, 5, and 6 are associated with linear synergies, SDG 3, and 7 with non-linear synergies. SDG interactions vary according to a country's income and region along with the gender, age, and location of its population. In summary, to achieve the 2030 Agenda the detected interactions and inequalities across countries need be tracked and leveraged to "leave no one behind."
Value creation in scene-based music production - the case of electronic club music in Germany
(2013)
The focus of this article is on the variability of value creation in the popular music industry. Recent trends in electronic music have been based on both the valorization of global tastes and of local specialities in performance and production. Depending on musical styles and market niches, local scenes have become important forces behind heterogeneous globalocal markets. At the same time, technological change and the virtualization of music production and distribution contribute to increasingly differentiated configurations of value creation. It is therefore necessary to reconstruct theoretically and empirically the new interplay among the local music production, digital media markets, and virtual communities that are involved. On the basis of empirical explorations in a German hot spot of electronic club-music production (the city of Berlin), the article indentifies local interaction practice and constellations of stakeholders. The findings show that value creation in these rapidly changing production scenes has moved away from the large-scale distribution of producer-induced media to audience-induced live performance and interactive soundtrack production. This change involves the rising importance of cultural embeddings such as taste building, reputation building among artists and producers, and local community building. Starting from an open theoretical problematization of value creation with regard to fluid scenes and shifting modes of production, the results of first empirical reconstructions are taken as inputs to an evolving discussion on the configurations of value creation in consumer-based strands of music production.
In Poland, EIA and SEA have been integrated into the planning system in a different way compared to Germany. There, EIA is performed within an independent procedure. For projects mandatorily requiring EIA, the respective county decides on the outcome of an EIA, whereas for projects with case-by-case screening the regional authority's council is responsible for this task. There are still significant uncertainties in the application of SEA which sometimes leads to conflicts with the EU provisions. In Poland, provisions for SEA were already made in the year 2000. Different SEA procedures are established for regional plans and for other environmental plans. Furthermore, in April 2004, provisions for the EA according to the Habitats Directive were made in the Polish nature protection act. EA according to the Habitats Directive is strongly linked to EIA and SEA. Poland is already experienced in the practice of EIA and SEA. However, there still is a lack of methodological guidelines. Furthermore, the different legal provisions and procedures need to be further adjusted to each other.
From 6 to 9 August 2012, intense rainfall hit the northern Philippines, causing massive floods in Metropolitan Manila and nearby regions. Local rain gauges recorded almost 1000mm within this period. However, the recently installed Philippine network of weather radars suggests that Metropolitan Manila might have escaped a potentially bigger flood just by a whisker, since the centre of mass of accumulated rainfall was located over Manila Bay. A shift of this centre by no more than 20 km could have resulted in a flood disaster far worse than what occurred during Typhoon Ketsana in September 2009.
Insights into the dynamics of human behavior in response to flooding are urgently needed for the development of effective integrated flood risk management strategies, and for integrating human behavior in flood risk modeling. However, our understanding of the dynamics of risk perceptions, attitudes, individual recovery processes, as well as adaptive (i.e., risk reducing) intention and behavior are currently limited because of the predominant use of cross-sectional surveys in the flood risk domain. Here, we present the results from one of the first panel surveys in the flood risk domain covering a relatively long period of time (i.e., four years after a damaging event), three survey waves, and a wide range of topics relevant to the role of citizens in integrated flood risk management. The panel data, consisting of 227 individuals affected by the 2013 flood in Germany, were analyzed using repeated-measures ANOVA and latent class growth analysis (LCGA) to utilize the unique temporal dimension of the data set. Results show that attitudes, such as the respondents' perceived responsibility within flood risk management, remain fairly stable over time. Changes are observed partly for risk perceptions and mainly for individual recovery and intentions to undertake risk-reducing measures. LCGA reveal heterogeneous recovery and adaptation trajectories that need to be taken into account in policies supporting individual recovery and stimulating societal preparedness. More panel studies in the flood risk domain are needed to gain better insights into the dynamics of individual recovery, risk-reducing behavior, and associated risk and protective factors.
