Establishment of Teak plantations for high-value timber production in Ghana

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.

Eckpunkte des Umweltressorts in einer sich wandelnden internationalen Sicherheitspolitik

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.

The ecology of the wild boar Sus scrofa near conservation areas

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.

Use of scavengers in the pretreatment of lignocellulosic biomass for improved chemicals production

Combined production of fuels and chemicals from wood This project examines an innovative approach for pre-treating wood in order to produce fuels and chemicals. In this approach, the researchers combine hot water treatment with so-called radical scavengers. Background Biofuels from wood have economic and ecological advantages as compared to fuels from corn starch and sugar cane (costs, availability, no conflict with food production). However, it is much more difficult to transform wood into biofuels. This is because the components of wood-cellulose, hemicelluloses and lignin-are strongly interwoven to protect the plant against external forces, in particular. In the production of biofuels, this impedes the enzymatic degradation of cellulose and lignocellulose into their respective sugars, which can subsequently be fermented to produce, for example, bio-ethanol. Therefore, it is necessary to pre-treat the wood in order to break up its structure and improve the enzymatic access. Aim One possible treatment of biomass would be to dissolve it in hot water, but this is hampered by cross-linking reactions of emerging lignin fragments. So-called 'radical scavengers' can stop these undesired reactions and make the wood much more soluble. This procedure is aimed at achieving, on the one hand, a cellulose fraction with improved enzymatic access and, on the other hand, a high-quality lignin fraction. The latter serves as a starting material for the production of aromatic chemicals. Significance The examined approach is aimed at producing fuels and aromatic chemicals which are today still gained from petrochemical resources. This opens up new avenues for gradually replacing fossil oil with biomass.

Institutions, Livelihoods and Conflicts (Phase 3 of NCCR-North-South)

The Thematic Node 1 is part of NCCR-North-South and delves into institutions, livelihoods and conflicts. Institutions regulate access to natural, political and symbolic resources and frame the political and social contexts within which social actors strive for their livelihoods. Latent or violent conflicts are also directly linked to the ways in which institutions regulate, or fail to regulate power imbalances within societies, and to the existence or lack of channels through which political grievances can be expressed and negotiated. The overall objective is to research the dynamic and changing roles of political, social, economic and cultural institutions in order to (1) understand how they regulate social interactions between and among individuals and groups (specifically regarding access to livelihood means, and peace and security), and (2) to enable a broader acceptance and legitimacy of institutions relevant for sustainable development. To understand these processes, we interlink our research with contemporary theoretical debates that conceptualise institutions not as given structures that influence peoples behaviour, but as socially constructed rules, regulations, norms and values. This crucial conceptualisation as 'socially constructed allows us to analyse institutions on the one hand as structures or frames established in order to achieve certain social, political or economic goals. On the other hand, it indicates that institutions are also changed, modified or even invented by certain social actors. The focus on actors highlights the potential of disagreement, and thus contestations among actors (state and non-state actors). Thus, 'institutions need to be researched as deeply embedded in social processes, influenced by social actors, their interests and unequal power relations.

Policy options to engage emerging asian economies in a post-Kyoto regime (POEM)

Objective: Developing countries are reluctant to make any binding commitment as their per capita emissions are low and climate abatement measures conflict with their main priorities on socio-economic development. The question is if there is a way to simultaneously provide sufficient energy (which is also the main source of GHG emissions), to support poverty alleviation and economic growth and achieve sufficient emission reductions. Finding an answer is the main aim of this project. It may be possible with a combination of policies and measures encompassing from international level to national level supported by committed international cooperation to achieve both the goals together. The main focus of the study is on India and China. The primary objective is to develop a portfolio of policy options including both international and national policies as well as institutional frameworks for international cooperation for these two emerging economies to engage them in climate protection measures under a post-2012 regime. By applying an integrated modeling framework, the study will explore possible multiple pathways which may exist for these countries to contribute into international climate initiatives without compromising their national development priorities. Specific objectives are: - developing country-specific integrated modeling framework to analyse policies and identify multiple pathways to achieve socio-economic and climate targets - identifying/designing international climate polices in post-Kyoto regime for future commitments and participations of emerging economies (India and China) - designing national polices (in socio-economic sectors, energy and environment) compatible with the global climate targets - designing and quantifying as much as possible the international co-operations needed to make the participation in a post-2012 regime acceptable at least in economic terms - disseminating the results to potential users for use in future negotiations.

Stellenwert und Wetehaltung der Gesellschaft gegenüber Flussbaulichen Eingriffen in der Vergangenheit und in der Gegenwart an ausgewählten Fliessgewässern unter Berücksichtigung der im Jahre 2004 umgesetzten EU-Wasserrahmenrichtlinie - Dissertation

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.

Sonderforschungsbereich (SFB) 564: Nachhaltige Landnutzung und ländliche Entwicklung in Bergregionen Südostasiens; Sustainable Land Use and Rural Development in Mountainous Regions of Southeast Asia, D 2.3: Efficiency of smallholder animal husbandry depending on intensity of management and genetic potential of livestock - Community driven breeding programmes: Optimisation of planning procedures

In the mountainous regions of North Vietnam, smallholder farmers try to sustain and improve their livelihoods under conditions of growing population density and land pressure. Livestock husbandry appears as major development opportunity for them. Yet, 'mountainous regions' are heterogeneous, comprising areas near town with favourable access to markets and infrastructure but higher land pressure and remote areas, disadvantaged concerning market and infrastructure access but disposing of larger cropping and pasture areas. Low and unsteady resource availability in marginal areas limits the possibilities for intensification of livestock production. One solution is to increase production efficiency through improved resource utilisation. In animal production this can be realised through the development of sustainable livestock breeding and management programmes, using genotypes with high productive adaptability. Such programmes will have different structures depending on short- and medium-term resource availability, production objectives and production intensity of respective smallholder production systems.Based on the results of phase 1 and 2, D2.3 focuses on planning procedures for livestock breeding and management programmes for four combinations of production systems and species/genotypes, namely production of lean pork with exotic higher-yielding breeds in demand-driven systems, production of branded pork from local Ban pigs including remote, resource-driven pig producers, production of beef in farming systems of different scale, organisational set-up and remoteness, and production of goat meat as niche product in systems in transition. The four programmes will respond to the large heterogeneity of smallholder production systems in the project area. In fulfilment of its research objectives, D2.3 relies on cooperation with sub-projects E4.1 (Product marketing) concerning the design of a pork marketing and quality control system in the frame of village breeding and pork marketing programmes, G1.2 (Innovations and sustainability strategies) and C4.1 (Land use modelling) on integrated modelling concerning the identification of most sustainable development paths for farms of different production intensity, scale, organisational set-up and remoteness, F2.3 (Livelihood risks) for characterisation of smallholder farms using key indicator regarding adoption of technologies in livestock husbandry, A1.3 (Participatory research) on adoption of optimised breeding strategies by farmers, and D5.2 (Aquaculture) on conflicts and complementarities in the use of feed resources for investigated livestock species and fish/aquaculture.
