Objectives: Sustainable management of tropical moist forests through private forest owners will become increasingly important. Media report that in Brazil, particularly in Amazonia, approx. 80 percent of the timber harvested is from illegal sources. Private management of forests according to internationally acknowledged standards offers an opportunity to significantly lower the portion of illegally cut timber. Moreover, it contributes significantly to the conservation of the Amazon forest. Private forest owners show a clear long-term commitment towards the implementation of management standards according that is ecologically compatible, socially acceptable and economically viable. The project area, a pristine forest in legal Amazonia in the transition zone between moist tropical forests and savannas (cerrado), is extremely diverse in floristic and faunistic terms. The institute cooperates with the private forest owner. Main tasks are to document the faunistic and floristic diversity, to calculate the Annual Allowable Cut and to elaborate concepts for site-specific silviculture. Results: To date (Oct. 2006) the following activities were started: - a comprehensive inventory system for planning at the FMU-level has been successfully introduced; - the inventory system for the annual coupe area has been designed and data for the first coupe are being processed; - the annual allowable cut is currently calculated based on the results of the above described inventories; - two fauna surveys are completed; one focusing on large mammals and one on the avi-fauna. A long-term monitoring concept to assess the influence of forest management on the faunistic diversity is currently under development; - forest zoning is completed applying terrestrial surveys and interpreting high-resolution satellite images; - a study on the use of Bethollethia excelsa-fruits (Brazil nuts) is currently implemented; - a study on timber properties of lesser known species is currently implemented.
We study the effects of plants and root-associated fungi on wind erosion within the alpine environment of Tibet. China is one of the countries most affected by desertification processes and Tibet, in particular, a key region in desertification combat. The presented project focuses on the Barkha Plain surrounded by Mount Kailash and the Lake of Manasarovar (Ngari Prefecture). This Western Tibet region experienced little scientific attention but, nowadays, faces rapidly increasing touristic activities and expanding local settlements associated with socio-economic changes that are serious threats to the delicate ecological balance and potential triggers of desertification. It exists almost unanimous agreement that revegetation is the most efficient and promising strategy to combat wind erosion and desertification in the long term. However, re-colonising success is often poor, mainly under extreme environmental conditions. Compared to conventional practices, the approach of the presented project attains better accordance with natural succession processes and promises acceleration of both plant and soil development and, conclusively, more efficient desertification control. The project assesses the potential of native plants and symbiotic fungi to control wind erosion and desertification processes. It aims to identify key plants and fungi that increase soil aggregate stability and efficiently drive succession into a natural and self-maintaining cycle of the ecosystem. Furthermore, it provides crucial information for implementing environmentally compatible and cost-effective measures to protect high-elevation ecosystems against desertification. Within three successional stages (early, intermediate, late), field investigations are performed on the basis of Modified-Whittaker plots. Classic methods of vegetation analysis and myco-sociology are combined with analysis of distribution patterns at different scales (patchiness, connectivity). Comprehensive soil analysis is performed comprising grain size distribution, aggregate stability, pH as well as water and nutrient contents. Additionally, important parameters of wind erosion are measured concurrently and continuously to assess their magnitude and variability with respect to vegetation and soil at different levels of development. The parameters addressed, include sediment transport, air temperature, radiation, precipitation, relative humidity as well as speed and direction of wind. Surface moisture is recorded periodically and roughness described. Species and environmental parameters are checked for spatial correlation. Cutting edge technologies are applied in laboratory work, comprising molecular methods for fungal species identification and micro-tomography to analyse soil structure. Furthermore, successfully cultivated fungi and plants are subject of synthesis experiments and industrial propagation in view of practical implementation in restoration measures.
Recent and predicted increases in extremely dry and hot summers emphasise the need for silvicultural approaches to increase the drought tolerance of existing forests in the short-term, before adaptation through species changes may be possible. We aim to investigate whether resistance during droughts, as well as the recovery following drought events (resilience), can be increased by allocating more growing space to individual trees through thinning. Thinning increases access of promoted trees to soil stored water, as long as this is available. However, these trees may also be disadvantaged through a higher transpirational surface, or the increased neighbourhood competition by ground vegetation. To assess whether trees with different growing space differ in drought tolerance, tree discs and cores from thinning experiments of Pinus sylvestris and Pseudotsuga menziesii stands will be used to examine transpirational stress and growth reduction during previous droughts as well as their subsequent recovery. Dendroecology and stable isotopes of carbon and oxygen in tree-rings will be used to quantify how assimilation rate and stomatal conductance were altered through thinning. The results will provide crucial information for the development of short-term silvicultural adaptation strategies to adapt forest ecosystems to climate change. In addition, this study will improve our understanding of the relationship between resistance and resilience of trees in relation to extreme stress events.
bifa wurde vom Bayerischen Staatsministerium für Umwelt und Gesundheit mit der Durchführung des Projekts IPP als Instrument des betrieblichen Klimaschutzes - eine Anleitung insbesondere für kleine und mittlere Unternehmen (KMU) beauftragt. Im Rahmen dieses Projekts werden u. a. acht Workshops mit Vertretern der Wirtschaft durchgeführt. Der erste Workshop fand bereits im Februar 2010 unter dem Motto Grüne Logistik: Visionen - Chancen - Risiken statt. Es nahmen 13 Unternehmer aus verschiedenen Bereichen der Logistik teil. Nach kurzen Impulsvorträgen zur Integrierten Produktpolitik und Grünen Logistik wurden in drei Arbeitsgruppen Möglichkeiten der Umsetzung von grüner Logistik im eigenen Unternehmen diskutiert und Ansatzpunkte gesucht, wie durch verstärkte Kooperation und Kommunikation die umweltbezogenen Vorteile der grünen gegenüber der normalen Logistik noch weiter ausgeschöpft werden können. Das äußerst heterogene Teilnehmerfeld wurde sehr positiv bewertet. So beschreibt ein Teilnehmer: Da waren ein Unternehmer mit eigenem Fuhrpark, ein kleiner mittelständischer Spediteur, ein großer mittelständischer Spediteur und ich aus der verladenden Wirtschaft. In der abschließenden Diskussion tauchte neben zahlreichen Ansatzpunkten zur Umsetzung immer wieder eine Frage auf: Was ist Green Logistics ? Wie können wir sie messen, was umfasst sie, wer nimmt daran teil und wer bezahlt sie? . Zur Abgrenzung der grünen gegenüber der normalen Logistik müssen Standards geschaffen werden, die den Unternehmen helfen, sich noch intensiver mit Möglichkeiten der Umweltentlastung im Bereich der Logistik auseinanderzusetzen. In einem weiterführenden Workshop im April 2010 setzten sich die Teilnehmer mit diesen Fragestellungen auseinander und erarbeiteten unter dem Titel Grüne Logistik: Standards generieren und umsetzen - aber wie? Vorschläge und Handlungsempfehlungen für die Praxis. Das IPP-Projekt ist für unterschiedliche Wirtschaftszweige von großem Interesse: So wurden weitere Workshops zu Themen wie Reach , Emissionen/ CDM , Bauwirtschaft und Recycling erfolgreich durchgeführt. Methoden: Analyse und Moderation sozialer Prozesse.

Da bisher keine Methode existiert, elektrische Energie in groesseren Mengen wirtschaftlich zu speichern, gewinnt die Speicherung von Waermeenergie zunehmend an Bedeutung. Es ist bekannt, dass eutektische Mischungen aus Fluoriden der Alkali- und Erdalkalimetalle (LIF, NaC18 NaF, MgCl2), aber z.B. auch reines Lithiumfluorid extrem hohe Schmelzwaermen besitzen. Fluoridmischungen koennen 2- bis 3-mal soviel Waerme speichern wie bisher benutzte Waermespeichermaterialien. Im Vergleich zum Bleiakkumulator weisen sie eine etwa dreissigmal hoehere Energiespeicherkapazitaet auf. Es besteht das Problem der Erreichung hoher Waermestromdichten zum Zweck einer moeglichst intensiven Waermezufuhr bzw. Waermeabgabe an der Oberflaeche.
