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.
In strict nature reserves and core zones of protected areas hunting and forestry operations are often restricted or banned. However, regarding the management of Wild boar, such hunt-free zones are discussed controversially and can lead to conflict. Hunters whose areas border no-hunting zones (and who have to reimburse farmers for crop damages caused by Wild boar) are concerned that the boars may evade effective population management by staying within the limits of the no-hunting zone, and farmers fear increased crop damage in the surroundings of such areas. Some conservationists are also concerned because Wild boars increasingly root protected habitats and can cause damage to rare plant assemblies. The three-year project Wild boar problem in the vicinity of protected areas by the Game Research Institute (Wildforschungsstelle) at the Centre for Agriculture Baden-Württemberg (LAZBW) aims at investigating if and how no-hunting zones might affect Wild boar activity, movement patterns, home range size, and habitat use, as well as crop damage caused by boars, by comparing these aspects between hunting-free zones and unprotected areas. Although there have already been a number of telemetry studies on Wild boar, including space use in the context of hunting activity, to date there is no study that has specifically investigated spatial and ecological aspects in and around protected areas. My dissertation Ecology of Wild boar Sus scrofa in the vicinity of protected areas is being carried out within the scope of the Game Research Institutes project and apart from the aims outlined above, further aspects of Wild boar ecology will be investigated, especially the role of Wild boar as bio-engineer and habitat creator for other species vs. unwanted damages at protected sites. Twenty-seven Vectronic GPS-GSM satellite collars with integrated activity sensors are available to tag Wild boars in three study areas: the non-protected Altdorfer Forest near Aulendorf with regular hunting activity and forestry, the nature reserve Wurzacher Ried with its ca. 700 ha core zone that is a strict reserve with no human activity, and the Biosphere Reserve Swabian Jura, especially in the surroundings of the former military training area near Münsingen and the 170 ha no-usage-area Föhrenberg.
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.
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.
Modern society is increasingly characterized by strong interactions between physical, infrastructure and human domains of the environment. Disasters are a critical collision between climatic and geophysical dynamics and are dramatic examples of people living in conflict with their environment. Disaster reduction and resilience are key priorities identified by the EC and the Hyogo Framework for Action. A sustainability framework for natural and technological hazards is of critical importance. Therefore the main goals of SCENARIO are: - To develop a European roadmap on sustainable mitigation of natural and induced technological hazards and risks which will support future European research priorities for the 7th framework programme, contribute to European policies on natural hazards, sustain the scientific community by providing a strategic picture and support potential end-users / stakeholders. A European roadmap may inspire a European Strategy for reduction and mitigation of effects by natural and induced technological Disasters and the building of greater resilience; - To integrate fragmented research approaches, concepts and results by incorporating existing experiences on natural disaster projects and initiatives at European level, including important national and international initiatives; - To assess and reorganise the Logic Value Chain of natural disasters through updating knowledge and state of the art on natural disaster prevention and mitigation in the context of modified societal and environmental features. In order to reach the objectives, SCENARIO will set up a networking process among existing projects and activities dealing with natural disasters with several workshops and meetings for knowledge sharing and dissemination. SCENARIO fits with Europe's goals regarding sustainable development in supporting environmental policies by defining a European roadmap on sustainable mitigation of natural and induced technological hazards and risks.

Plants grow in complex ecological networks, and show finely tuned adaptations to attact mutualists such as pollinators, and deter enemies such as herbivores. To do so, plants use volatile signals (BVOCs biogenic volatile organic compounds) that are emitted from vegetative (e.g. leaves) or flowers. Leaf volatiles are often thought to be involved in defense, whereas floral volatiles are traditionally interpreted as attractants for pollinators. However, recent studies have shown that floral scent may as well be involved in defending reproductive structures against antagonists. This can be achieved by emitting repellent compounds from flowers. The obvious need of plants to attract pollinators to flowers on the one hand, and to defend flowers on the other hand, puts them into a dilemma. Such signaling dilemma or trade-offs suggest optimal fitness outcomes may be a compromise between attraction (pollinators, parasitoids) and deterrence (herbivores); a key factor selecting for differential signaling may thus be the abundance and species identity of these interacting organisms in a given habitat. Signaling conflicts may also differ among pollination systems, e.g. when pollinators are also herbivores (moth pollination), attracting an herbivore is unavoidable for pollination. Under strong herbivore attack, however, plants may even switch pollination system by changing BVOC signaling to escape the herbivore pressure. This particular project will focus on ecological and evolutionary aspects of flower signaling to pollinators and the impact of novel herbivores on this mutualism. Up till now, we know surprisingly little about how herbivore induced changes in floral volatiles (HICFV) and the resulting change in flower attractiveness to pollinators. This IP will investigate HICFV after attack of established and novel herbivores (both on shoots and roots) and its molecular basis and variability. Lastly, natural selection on HICFV will be studied in populations with and without invasive herbivores, to asses their impact on the evolution of this key plant signaling trait and model future evolutionary change.

LCA approaches are part of the broader field of sustainability assessment often connected to different disciplines. To increase the efficacy of sustainability decision making, LCA is to take into account broader externalities, broader interrelations and different application/user needs with often conflicting requirements (dynamic models; integration of environmental, economic, and social aspects; accessibility and user friendliness, etc). Roughly, development should be oriented to: - 'deepening', to improve reliability and usability by more adequately incorporating empirical mechanisms - 'broadening', to improve the significance, by expanding the scope of sustainability impacts and better linking to neighbouring models - 'leaping forward' by a revision/enrichment of foundations, through the crossing with other disciplines for sustainability evaluation. CALCAS develops analysis and development along two lines: 1 science framework; 2 user needs (Industry, Research organisations, Government, Consumers, NGOs); the results, are crossed to draw up mid- long-term research lines and road maps, including measures for implementation. Advanced results will often not be in line with the current ISO14040 series definitions and requirements on LCA, creating a need for reformulation. Partnership combines LCA 'producers' and 'users' and involves, with different responsibilities, a significant and highly qualified part of European scientists. Thus, the project promotes the networking both 'cross', among the scientific sectors, and 'vertical' between them and users. Expert working groups, cross-fertilisation workshops, and an open consultation of all scientific sectors and users, based on a Blue Paper combining intermediate proposals are inputs to the final results, both as described models and tools and as research tasks to be accomplished. They also promote dissemination and joint actions for training, knowledge exchanges and common projects. Prime Contractor: Ente per le Nuove Tecnologie, l'Energia elL'Ambiente; Roma; Italy.
