Background and Objectives: The project area is located in the Ashanti Region of Ghana / West Africa in the transition zone of the moist semideciduous forest and tropical savannah zone. Main land use in this region is subsistence agriculture with large fallow areas. As an alternative land-use, forest plantations are under development by the Ghanaian wood processing company DuPaul Wood Treatment Ltd. Labourers from the surrounding villages are employed as permanent or casual plantation workers. Within three forest plantation projects of approximately 6,000 ha, DuPaul offers an area of 164 ha (referred to as Papasi Plantation) - which is mainly planted with Teak (Tectona grandis) - for research purposes. In return, the company expects consultations to improve the management for sustainable timber and pole production with exotic and native tree species. Results: In a first research approach, the Papasi Plantation was assessed in terms of vegetation classification, timber resources (in qualitative and quantitative terms) and soil and site conditions. A permanent sampling plot system was established to enable long-term monitoring of stand dynamics including observation of stand response to silvicultural treatments. Site conditions are ideally suited for Teak and some stands show exceptionally good growth performances. However, poor weed management and a lack of fire control and silvicultural management led to high mortality and poor growth performance of some stands, resulting in relative low overall growth averages. In a second step, a social baseline study was carried out in the surrounding villages and identified landowner conflicts between some villagers and DuPaul, which could be one reason for the fire damages. However, the study also revealed a general interest for collaboration in agroforestry on DuPaul land on both sides. Thirdly, a silvicultural management concept was elaborated and an improved integration of the rural population into DuPaul's forest plantation projects is already initiated. If landowner conflicts can be solved, the development of forest plantations can contribute significantly to the economic income of rural households while environmental benefits provide long-term opportunities for sustainable development of the region.

Die aktuelle politische Lage erfordert eine Überprüfung und eventuelle (Neu-) Justierung der Politik. Im Juni 2023 hat die deutsche Bundesregierung zudem erstmals eine nationale Sicherheitsstrategie vorgestellt. Der darin integrierte breite Sicherheitsbegriff umfasst den Schutz der natürlichen Lebensgrundlagen als einen elementaren Pfeiler. Die Aktivitäten, Maßnahmen und Ziele des Umweltressorts sind, auch mit und neben anderen Akteuren, im Ressortkreis wie auch auf europäischer/internationaler Ebene somit relevant für die Sicherheit und die Umsetzung der Strategie. Hieraus ergibt sich Forschungsbedarf, um z.B. eine umweltgerechtere, nachhaltige Sicherheitspolitik bzw. eine krisenpräventivere Umwelt- und Entwicklungspolitik zu gestalten und konkrete Möglichkeiten zur Umsetzung der Ziele der nationalen Sicherheitsstrategie und des immanenten breiten Sicherheitsbegriffes durch die Umweltpolitik in Deutschland aufzuzeigen. Die Analyse von drei noch auszuwählenden Themenfeldern wird abklären, in welchen konkreten Bereichen welche nationalen politischen Maßnahmen in Hinblick vor allem auf die Zuständigkeiten des BMUV auf internationaler Ebene am effektivsten verhindern können, dass 1) Konflikte zu Umweltzerstörung beitragen, 2) Umweltzerstörung zu Konflikten beiträgt und 3) Umweltschutzmaßnahmen zu Konflikten beitragen. Die Erkenntnisse und Herausforderungen sollen mit den Akteuren reflektiert und deren Austausch ermöglicht werden, um eine kohärente Politikgestaltung im Hinblick auf die Ziele zu fördern. Dabei sollen auch gute und schlechte Praxisbeispiele erfasst werden und in die Prozesse einfließen.
Recent legislation (Cross Compliance, Soil Protection Act of Germany) has forced farmers to keep the level of soil organic carbon (SOC) in their arable soils within certain limits. In the region Cologne/Bonn, an unfavourable constellation of factors (low cattle density, intensive soil tillage etc.) resulted in low contents and stocks of soil organic carbon (SOC). Thus, the farmers are challenged to increase the humus content of their soils. However, the rapid achievement of this objective may conflict (i) specifically with the interests of the local waterworks, and (ii) generally with the environmental targets of the European Community Nitrate Directive: Within Nitrate Vulnerable Zones, application rates of organic manures are restricted to avoid diffuse water pollution from nitrate. Against this background, our project aims at optimizing a system of soil use and management, that (i) assures an adequate humus support and sustainable soil fertility, and that (ii) minimizes the pollution of groundwater. The experiments include (i) quantifying the spatial heterogeneity of various soil parameters (Corg, Ntotal, Nmin, texture, nutrients) within arable fields in order to assess the possibility of a site-specific management; (ii) repeated sampling at selected sites in order to quantify C and N dynamics (incl. nitrate leaching) under different management options; (iii) spiking of soils with 15N in order to detect the fate of fertilizer N; (iv) modelling C and N dynamics for selected fields on the basis of long-term management data.
Background: It has been hypothesized, that children could be more vulnerable to radio frequency electromagnetic field exposures from mobile telephones than adults, but no epidemiological studies of the relationship have been performed so far. The lack of knowledge causes conflicting recommendations from decision-makers, leading to anxiety and insecurity in the population. WHO has put a case-control study on childhood brain tumours as high priority on their 2006 research agenda on radio frequency electromagnetic fields. Objectives: The main goal of the study is to investigate whether use of mobile telephones increases the risk of developing brain tumours for children or adolescents. In addition, our study will provide a comprehensive dataset to investigate other potential risk factors for childhood brain tumour. Study design: The questions under study will be investigated by means of a case-control study in Denmark, Norway, Sweden and Switzerland. Cases will be identified through a combination of registry data and information from the wards treating the patients (e.g. Swiss Paediatric Oncology Group: SPOG). All incident cases of brain tumour in the age group 7-19 years between May 2004 and April 2008 will be invited to participate. In total, the study is expected to include 550 cases of brain tumours in the participating countries, thereof 100 originating from Switzerland. For each case, two control persons will be randomly selected from the general population, matched on age, sex and geographic regions. Exposure assessment: Information on the extent of exposure to radio frequency fields from mobile phones and on other known and suspected risk factors for childhood brain tumours will be obtained by means of computer assisted personal interviews conducted by an interviewer trained for this purpose. The interviews will take place either at the hospital or at the study participant's home. Objective information on the frequency and duration of mobile phone use will be obtained from mobile phone operators and from the information stored in the telephone that is in current use. Data analyses: The data will be analyzed using established statistical methods for case-control studies, primarily via logistic regression models adjusted for potential confounding factors. In order to investigate potential gene-environment interactions, DNA from saliva samples will be extracted and analysed. Polymorphisms in genes that affect oxidative metabolism, detoxification of carcinogens, DNA stability and repair, or immune response, are candidates that might confer genetic susceptibility to brain tumors.
Fliessgewässer unterstehen dauernden Veränderungen. Diese können natürlich oder anthropogen bedingt sein. Der Mensch 'korrigiert seine Flüsse und Bäche schon seit Jahrhunderten. Seit der Industrialisierung wurden die Eingriffe jedoch zunehmend stärker und umfangreicher. Ganze Flusssysteme wurden begradigt, Wasserkraftwerke stauen Flüsse über hunderte Kilometer an und Schleusen machen Fliessgewässer wiederum schiffbar. Heutzutage hat sich die Denkweise umgekehrt. Weniger Eingriffe, Rückbau von flussbaulichen Einrichtungen und die Forderung nach mehr Naturnähe bestimmen mittlerweile die Gedanken der Wasserwirtschaft. Erst recht durch die Umsetzung der EU-Wasserrahmenrichtlinie, die im Allgemeinen eine Verbesserung der Gewässer fordert. Laut dieser Forderung müssten einige stark veränderten Fliessgewässer von den Verbauungen 'befreit werden. Die Arbeit soll versuchen aufzuzeigen, wieso es auch wünschenswert wäre alte Eingriffe in die Flüsse zu schützen, weil sie besonders und einmalig sind und sie nach eingehender Überprüfung als kulturhistorische Denkmäler auszuweisen. Deshalb soll geklärt werden wie sich solche flussbauliche Konstruktionen zu kulturhistorischen Bauwerken entwickeln konnten . Infolgedessen soll besonders Wert auf die Identifikation der Bevölkerung und der Erbauer mit den jeweiligen Objekten gelegt werden. Welche Wünsche und Erwartungen hegten die Menschen bei der Erstellung der flussbaulichen Bauwerke? Welche Konflikte traten zutage? Wie hat sich der Stellenwert der Bauwerke über die Zeit bis heute verändert? Um die heutige kulturhistorische Bedeutung von Fließgewässern zu verstehen, ist die Kenntnis über die frühere Beziehung des Menschen, besonders der Flussanwohner, zu ihren Flüssen von besonderer Relevanz. Nur so kann geklärt werden wieso man heute das Interesse besitzt verbaute Flüsse zu erhalten, obwohl Möglichkeiten bestünden sie aus ihrem 'Korsett zu befreien. Diese Fragestellungen sollen am Beispiel des Hochrheins und dem schweizerischen Linthwerk untersucht werden. Als Untersuchungsmethode dienen das Studium und die Analyse diverser schriftlicher Quellen.
Landscapes and the natural environment in general have become resources that are increasingly contested by different stakeholders (Hunziker, et al., 2008). This is both the case for spectacular natural and cultural landscapes (cf. Antrop, 2006; UNESCO, 2010) as well as for ordinary landscapes (cf. Kienast, et al., 2007). Landscapes offer natural resources that provide vital life-support services and that often are of immense economic value (Antrop, 2006). But they are also a reference to the sense of place (including heritage) for many people and thus they provide immaterial services as well. Inappropriate landscape development can change and obliterate locally distinctive characteristics and cultural meanings, creating a break between communities and their past. (Antrop, 2005 in Stephenson, 2008:127) The sustainable use of natural resources and the quality of landscape services (i.e. ecosystem services) not only depends on stakeholders practices but also on their perception and interests (cf. Ormaux, 2005; Backhaus, et al., 2008). For example an area that is covered by rainforests can be regarded in rather different ways. Farmers working on fields adjacent to this rainforest may regard it as a source of vermin that endanger their crops that therefore ought to be cut down and made arable. Rainforests are also resources of timber for the timber industry. Wild animals living in the forests and rare plants attract hunters and collectors as well as biologists and nature lovers and indigenous people may regard it as a sacred place. Tourists are eager to visit this spectacular ecosystem for contemplation, observation but also to indulge in group activities. And lastly a global community of people in favour of the protection of rainforests is interested in its conservation even if they never set a foot in it. It is obvious that some of these interests are conflicting and cannot be satisfied all at the same time. This not only applies for tropical rainforests but also for many protected areas and other types of landscapes including urban landscapes (or cityscapes). Interests are closely connected to perceptions of the environment influencing each other. Both are moreover embedded in social and cultural structures. Therefore, the sustainable development of landscapes needs to take into account peoples cultural and social background as well as their preferences and interests. The proposed project attempts to do this in selected case study areas in Malaysia that are compared to similar studies undertaken in Switzerland.
Traditional state-centric accounts of climate change governance fail to capture the dynamics that characterise international negotiations on climate change mitigation and adaptation. These accounts are largely based on rational choice models of conflict and cooperation in international relations, which assume that states are unitary actors, and that they act rationally in the pursuit of clearly-defined goals. Because of the nature of their assumptions, rational choice models tend to focus exclusively on the international legal process conducted under the auspices of the United Nations Framework Convention on Climate Change. This dissertation, by contrast, adopts a transnational relations approach, which argues that a wider interpretation of governance is required to understand the dynamics of climate change regulation. By defining the constitutive elements of climate change governance, the dissertation aims to highlight the complex web of relationships at national, international, and transnational levels that effect regulatory processes and outcomes, and emphasises the different but complementary roles that states and non-state actors play in climate change governance.

Welche Rolle spielt das 'Naturerleben' im Kontext des Verhaltens in der Landschaft? Treten Konflikte auf zwischen Naherholung, Landwirtschaft und Naturschutz? Vorgehensweise: Untersuchungsdesign: Trend, Zeitreihe.
In my Phd-study, I examine the resource conflict over industrial logging in the South Moresby area on Haida Gwaii (former Queen Charlotte Islands) from 1974 to 1993. On this remote archipelago on British Columbias west-coast, a fierce dispute over logging practices, land rights, Aboriginal land claims and environmental issues had emerged in the face of devastating logging practices were not only threatening to destroy large parts of Moresby Island but also resulted in the destruction of salmon streams. The two major natural resources available on the islands were at stake during the 'war in the woods.' Together with environmentalist, the Haida First Nation successfully fought for the preservation of Gwaii Haanas (South Moresby Island) with blockades, protests, environmental campaigns, lobbying and legal action. The area is now protected as the 'Gwaii Haanas National Park Reserve.-' Using a cultural approach combining aspects of 'storytelling,' the 'cultural memory' and 'actor-network-theory' (ANT), the core question arises whether the (Western) dualisms between 'nature' and 'culture' and between 'fact' and 'fiction' should be dissolved. Latour argues that such dualisms and even the separation between the human and non-human world (i.e., the world of things) do not exist. Assmann claims that we do not necessarily remember what has really happened', but what was repeatedly told us to have happened. Along with Thomas King, J. Edward Chamberlin and William Cronon, I stress the point that stories - fictitious or based on facts - do matter. The effect of stories on the way we understand our past, might often be more important than that of 'hard' facts: Stories shape both a societys concept of the past and its present identity. Canada, with its heterogeneous population, is a particularly interesting place to conduct research about different concepts of 'nature' and culture'. Analyzing the different stories that evolved around South Moresby, and taking into account diverging messages of native and non-native stories, offers a new perspective on similar resource conflicts that continue to exist and arise all over the world.
Studying resource-scarce areas in South Asia and East Africa, this research project seeks to identify new livelihood strategies for groups vulnerable to exclusion, particularly strategies that diminish reliance on natural resources. Special attention is given to the governing institutional context in order to reveal ways of supporting equity-effective institutions. We thereby ask the following guiding questions: How the livelihoods are secured at present, and what is the situation specifically of food security? What kind of alternative livelihood options (including options to secure food) do exist in these contexts, or are being fostered by development interventions? Who has access to these opportunities (i.e. is included), and who not (i.e. is excluded)? What are the institutional processes that produce these exclusions or inclusion? And how could equity-effectiveness of the institutional context be supported? Finally - looking into the future, which scenarios of impacts of climate change on livelihood security (food production etc.) exist? Which impacts could these processes have onto the already contested field of securing livelihoods; and which policies are necessary to cope with this? Our in-depth study of the changing patterns of livelihood strategies and identification of enabling livelihood options for marginal communities in the face of resource and food scarcity and social conflicts - especially beyond the (presently dominant) focus on natural resources - contributes to a comprehensive understanding of social conflicts and processes of exclusion and inclusion of certain social groups in the marginal areas, and reveals avenues for alternative livelihood options and support structures. These insights will then be used for a 'research informed constructive dialogue' with concerned stakeholders and practitioners to find ways of improving existing practices by using transdisciplinary approach. Case studies: Transnational Land Deals and Local Livelihoods in Tanzania (Martina Locher) In recent years there has been a rapid growth in the number of investors from Western, Asian and Gulf countries acquiring large shares of agricultural land in poorer countries, in order to plant food or biofuel crops, for forestry plantations and many other purposes. The strong increase of such investments triggered a lively debate on their impacts in host countries. Supporters claim that they entail new income opportunities, improved technologies and infrastructure in rural areas. Critics draw attention to violations of (formal and informal) land rights held by local people, decreasing access to and degradation of natural resources, and ultimately increased food insecurity in the respective areas. In sub-Saharan Africa, a hotspot region for foreign investment, the rush for foreign land happens in a context of unstable farming existences. Population growth and climate change lead to increased pressure on natural resources. usw.
