Territoriality is a central issue in indigenous peoples struggles. The territorial struggles involve struggles over the control of natural resources and over political participation and representation, but also over the perception of territorial rights and the symbolic representation of the territory. These struggles are carried through both in material and symbolic ways through recurring to different discourses and representations that provide legitimation for the territorial claims of the group. The study is located in the Northern Autonomous Atlantic Region of Nicaragua. The study concerns the territorial strategies, conceptions and practices of the indigenous people and other actors. Territorial conflicts exist between the autonomous region and the central government of Nicaragua, between mestizo settlers and indigenous people, between different indigenous groups, and between these and development agents such as conservation projects. The study focuses on how territorial discourses and representations are used to legitimate territorial control. Environmental, historical and cartographical discourses are the most important discourses recurred to. The influence of discourses and representations on the territorial practices and policies of the different actors, the links between the local struggles and global processes, and the broader structural factors impacting on the territorial struggles are also analysed. Among the structural factors are the problems related to land tenure and management and the use of natural resources, the advance of the agricultural frontier, the institutional weaknesses of the central and regional governments and the legislative processes. The territorial discourses are both recurred to in a strategic way and also grounded in local ideals and practices. The discourses have produced real effects for example in legislation, land tenure systems, political representation and environmental practices. Although the use of discourses and representations are an important power tool in territorial struggles, territorial control cannot be effectively accomplished merely through representing territorial claims in a legitimate way or through reforming legislation, as the conflicts are also largely a result of structural factors affecting the region. The fieldwork was carried out during a total of twelve months between 2000 and 2002. The research methods used were semi-structured interviews, participant observation and participatory research methods. A broad range of literary sources were also used to collect data. The study is located within the field of critical political geography with a discursive political ecology approach. It can be called a critical realist approach to the discursive analysis of indigenous territoriality.

Regeneration ecology, diversity of native woody species and its potential for landscape restoration was studied in the remnant natural forest at the College of Forestry and Natural Resources at Wondo Genet, Ethiopia. The type of forest is Afromontane rainforest , with many valuable tree species like Aningeria adolfi-friederici, and it is an important provider of ecological, social and economical services for the population that lives in this area. The study contains two parts, natural regeneration studies (at the natural forest) and interviews with farmers in the nearby village of the remnant patch. The objective of the first part was to investigate the floristic composition, densitiy and regeneration profiles of native woody species in the forest, paying special attention to woody species that are considered the most relevant (socio-economic). The second part provided information on woody species preferred by the farmers and on multiple uses of the adjacent natural forest, it also provided information and analysed perceptions on forest degradation. Systematic plot sampling was used in the forest inventory. Twenty square plots of 20 x 20 m were assessed, with 38 identified woody species (the total number of species was 45), representing 26 families. Of these species 61% were trees, 13% shrubs, 11% lianas and 16% species that could have both life forms. An analysis of natural regeneration of five important tree species in the natural forest showed that Aningeria adolfi-friederici had the best regeneration results. An analysis of population structure (as determined by height classes) of two commercially important woody species in the forest, Aningeria adolfi-friederici and Podocarpus falcatus, showed a marked difference: Aningeria had a typical “reversed J” frequency distribution, while Podocarpus showed very low values in all height classes. Multi dimensional scaling (MDS) was used to map the sample plots according to their similarity in species composition, using the Sørensen quantitative index, coupled with indicator species analysis .Three groups were identified with respective indicator species: Group 1 – Adhatoda schimperiana, Group 2 – Olea hochstetteri , Group 3 – Acacia senegal and Aningeria adolfi-friederici. Thirty questionnaire interviews were conducted with farmers in the village of Gotu Onoma that use the nearby remant forest patch. Their tree preferences were exotic species such as Eucalyptus globulus for construction and fuelwood and Grevillea robusta for shade and fertility. Considering forest land degradation farmers were aware of the problem and suggested that the governmental institutions address the problem by planting more Eucalyptus globulus. The natural forest seemed to have moderate levels of disturbance and it was still floristically diverse. However, the low rate of natural regeneration of Podocarpus falcatus suggested that this species is threatened and must be a priority in conservation actions. Plantations and agroforestry seem to be possible solutions for rehabilitation of the surrounding degraded lands, thereby decreasing the existent pressure in the remnant natural forest.

Nature, science and technology. The image of Finland through popular enlightenment texts 1870-1920 This doctoral thesis looks at how Finnish popular enlightenment texts published between 1870 and 1920 took part in the process of forming a genuine Finnish national identity. The same process was occurring in other Nordic countries at the time and the process in Finland was in many ways influenced by them, particularly Sweden. In Finland the political realities under Russian rule especially during the Russification years, and the fact that its history was considered to be short compared to other European countries, made this nation-building process unique. The undertaking was led by members of the national elite, influential in the cultural, academic as well as political arenas, who were keen to support the foundation of a modern Finnish identity. The political realities and national philosophy of history necessitated a search for elements of identity in nature and the Finnish landscape, which were considered to have special national importance: Finland was very much determined as a political entity on the basis of its geography and nature. Nature was also used as means of taking a cultural or political view in terms of, for example, geographical facts such as the nation s borders or the country s geographical connections to Western Europe. In the building of a proper national identity the concept of nature was not, however, static, but was more or less affected by political and economic progress in society. This meant that nature, or the image of the national landscape, was no longer seen only as a visual image of the national identity, but also as a source of science, technology and a prosperous future. The role of technology in this process was very much connected to the ability to harness natural resources to serve national interests. The major change in this respect had occurred by the early 20th century, when indisputable scientific progress altered the relationship between nature and technology. Concerning technology, the thesis is mainly interested in the large and at the time modern technological manifestations, such as railways, factories and industrial areas in Finland. Despite the fact that the symbiosis between national nature and international but successfully localized technology was in Finnish popular enlightenment literature depicted mostly as a national success story, concerns began to arise already in last years of the 19th century. It was argued that the emerging technology would eventually destroy Finland s natural environment, and therefore the basis of its national identity. The question was not how to preserve nature through natural science, but more how to conserve such natural resources and images that were considered to be the basis of national identity and thus of the national history. National parks, isolated from technology, and distant enough so as to have no economic value, were considered the solution to the problem. Methodologically the thesis belongs to the genre of science and technology studies, and offers new viewpoints with regard to both the study of Finnish popular enlightenment literature and the national development process as a whole.

Forest destruction for agriculture continues to be a major threat to the rich biological diversity in the East Usambara Mountains in the north-eastern corner of Tanzania. The highest ratio of endemic plant and animal species found on 100 km2 anywhere in the world is depending on the remaining natural forests. Forests are vitally important for the local population in many different ways, and nationally they are an important source of water and hydroelectricity. The soils, of low fertility and mostly acidic Ferrasols, mainly have the nutrients in the topsoil. After clear-cutting, the soils soon become poor when the topsoil is eroded. High-value cardamom is nowadays unsustainably cultivated in the natural forests of the East Usambaras. The general aim was to study the possibilities to develop new profitable and sustainable agroforestry systems for the benefit of the local people that could contribute to relieving the pressure on the remaining natural forests in the East Usambara Mountains. Results from a spice crop agroforestry trial, established in cooperation with a local farmer, showed a clear advantage of intercropping cardamom (Elettaria cardamomum) and black pepper (Piper nigrum) with trees, especially with Grevillea robusta. The nitrogen fixing tree species Gliricidia sepium also improved the nitrogen and organic matter content of the soil over levels found in the natural forest. With improved agroforestry methods for spice production the households generated as much as13 times the net income obtained with traditional forest cultivation practices. There are thus sustainable and profitable ways to cultivate spices as cash crops in well-managed homegardens. However, the farmers need stable markets, access to credit and comprehensive extension services. The soil fertility depletion should be reversed with organic manure application and an enabling policy environment for the smallholder-farming sector. Strong farmers organisations and equal rights to resources and decision-making are needed. Organic spices have an increasing demand, and their export would be profitable for these farmers. What is, however, most needed for a change is a political will of a government that understands the importance of agricultural and forestry development for poverty reduction.

This thesis studies the use of natural resources for leisure time activities. The method used is Material Input per Service Unit (MIPS method). Leisure time has an increasing effect on the material flows of households, and that way has a bigger pressure on the environment. The most popular way of spending spare time in Finland is to watch TV and to listen to music or radio. Regardless of these, this thesis takes a closer look at boating, playing a musical instrument and visiting a theatre and tries to quantify their material flows. MIPS calculations of this thesis are case-studies and do not tell the whole truth about the hobbies. The aim was to have an overview about the magnitude of the activities. In the boating calculations, inside the system boundaries there are the boat itself, transport of the boat, outboard motor, gasoline consumption of the outboard motor, travelling to and from the harbour, and the harbour infrastructure. Calculations of playing a music instrument consider the instrument itself, music school and its maintenance, and travelling to the school. In the case of theatre the included things are theatre house and its maintenance, decor and costumes of the plays, transport of the decor, and travelling of the audience. The results of this thesis suggest that the biggest material flow of boating comes from travelling to and from the harbour and from the harbour infrastructure. The gasoline consumption of the outboard motor also makes a difference. One hour of boating with a rowing boat consumes 1 kg of abiotic materials. Boating with an outboard motorboat consumes astonishing 113 kg of abiotic resources. Visiting a music lesson for one hour consumes 9 kg of abiotic resources when travelling there by bus. One hour in a theatre play consumes 17 kg of abiotic materials when travelling by bus. Transport has a significant role on the resource consumption of leisure time activities.

Tutkielmassa tarkastellaan liikuntaharrastusten luonnonvarojen kulutusta MIPS (material input per service unit, suom. materiaalipanos palvelusuoritetta kohden) -menetelmällä. MIPS-menetelmä perustuu ekotehokkuusajatteluun ja sen tavoitteena on suhteuttaa tuotteen tai palvelun elinkaaren aikainen luonnonvarojen kulutus siitä saatavaan palveluun. Tässä tutkimuksessa tarkastellaan liikuntaharrastusten materiaalivirtoja erilaisissa liikuntapaikoissa yhden henkilön harrastetuntia kohden. Tarkasteltavia liikuntapaikkoja ovat kevyen liikenteen väylä, kuntorata, liikuntasali ja -halli, jäähalli, uimahalli, kuntokeskus sekä lämmitetty ja lämmittämätön tekonurmikenttä. Tutkielman laskelmat perustuvat pääosin tapaustutkimuksiin suomalaisista liikuntapaikoista. Laskelmissa on huomioitu liikuntapaikalle matkustaminen, liikuntapaikan rakentaminen sekä sen ylläpito ja käyttö. Tarkasteltujen liikuntaharrastusten abioottisten luonnonvarojen kulutus vaihteli 1,7 28 kg:n välillä yhden henkilön harrastetuntia kohden. Abioottisten luonnonvarojen kulutukseen vaikutti eniten liikuntapaikalle matkustaminen. Tarkastelluista liikuntaharrastuksista eniten abioottisia luonnonvaroja ja ilmaa kulutti uimahallissa uiminen. Kuntoradoilla ja kevyen liikenteen väylillä harrastettavien ulkoilulajien MIPS-luvut olivat alhaisimmat. Liikuntaharrastukset erosivat toisistaan eniten veden kulutuksessa, jonka MIPS-luvut vaihtelivat 40 ja 1400 kg:n välillä. Korkein veden MIPS-luku oli jäähallissa tapahtuvalla liikunnalla. Ilman kulutus liikuntaharrastuksissa oli 0,1 6,2 kg harrastetuntia kohden. Tulosten perusteella liikuntaharrastusten luonnonvarojen kulutusta voitaisiin tehokkaimmin vähentää kulkemalla liikuntapaikalle henkilöauton sijaan julkisilla kulkuneuvoilla ja hyödyntämällä lähiympäristön tarjoamia liikuntapaikkoja. Myös liikuntapaikkojen kävijämäärien maksimoiminen on tärkeää harrastetunnille kohdistuvien materiaalivirtojen pienentämiseksi. Tutkielma on toteutettu osana FIN-MIPS Kotitalous tutkimushanketta.

The dissertation focuses on the recognition of the problems of uneven regional development in Finland in the 1950s, and the way the idea of controlling this development was introduced to Finnish politics. Since it is often stated that Finnish regional policy only began in the mid-1960s, the period at hand is considered to fall in the time before regional policy. However, various ideas, plans and projects of regional development as well as different aims of development were brought forward and discussed already in the 1950s. These give an interesting perspective to the ideas of later regional development. In the 1950s, many Finnish politicians became more conscious of the unavoidable societal change. The need for overall modernisation of the society made it reasonable to expect a growing level of unemployment and eagerness to migration. The uneven distribution of well-being was also feared to cause discontent and political changes. International experience proved interfering in the regional development possible when using the argument of public interest ; the measures taken increased the level of well-being, helped sustain societal balance, and supported national economy. Many of the development projects of the 1950s focused on Northern Finland, the natural resources of which were considered an important reserve and the political climate of which was regarded unstable. After the late 1940s, regional development was discussed frequently both on the national and the regional level. Direct and indirect support was given to less developed areas and the government outlined thorough investigations in order to relieve the regional problem. Towards the end of the decade, the measures taken were already often connected to the idea of equality. In the 1950s the conflicts within and between the largest Finnish political parties significantly affected the decisions of regional development. There are three case studies in this qualitative research based on the narrative method. The case studies clarify the characteristics of the 1950s regional development. In the first one, the representatives of the northern region and the state first discuss the location of a state-run nitrogen fertilizer factory and later the location of a new university. In the second, the aims and perspectives of private entrepreneurs and the state collide due to ideas of statist industrialisation projects and later due to an idea of a tax relief targeting northern industry. In the third case, the main role is given to the changing rural areas, in relation to which societal development and urbanisation were often measured. The regional development of the 1950s laid groundwork for the new, more established regional policy. The early problem solving actions were aimed both at the prevailing situation and the future and thus showed the way for the upcoming actions. Regional development policy existed already before regional policy.

The Baltic Sea is a geologically young, large brackish water basin, and few of the species living there have fully adapted to its special conditions. Many of the species live on the edge of their distribution range in terms of one or more environmental variables such as salinity or temperature. Environmental fluctuations are know to cause fluctuations in populations abundance, and this effect is especially strong near the edges of the distribution range, where even small changes in an environmental variable can be critical to the success of a species. This thesis examines which environmental factors are the most important in relation to the success of various commercially exploited fish species in the northern Baltic Sea. It also examines the uncertainties related to fish stocks current and potential status as well as to their relationship with their environment. The aim is to quantify the uncertainties related to fisheries and environmental management, to find potential management strategies that can be used to reduce uncertainty in management results and to develop methodology related to uncertainty estimation in natural resources management. Bayesian statistical methods are utilized due to their ability to treat uncertainty explicitly in all parts of the statistical model. The results show that uncertainty about important parameters of even the most intensively studied fish species such as salmon (Salmo salar L.) and Baltic herring (Clupea harengus membras L.) is large. On the other hand, management approaches that reduce uncertainty can be found. These include utilising information about ecological similarity of fish stocks and species, and using management variables that are directly related to stock parameters that can be measured easily and without extrapolations or assumptions.

Growing human populations and increasing exploitation of natural resources threaten nature all over the world. Tropical countries are especially vulnerable to human impact because of the high number of species, most of these endemic and still unknown. Madagascar is one of the centers of high biodiversity and renowned for its unique species. However, during the last centuries many endemic species have gone extinct and more are endangered. Because of high natural values, Madagascar is one of the global conservation priorities. The establishment of Ranomafana National Park (RNP) was intended to preserve the unique nature of Madagascar. Containing several endemic and threatened species, Ranomafana has been selected as one of UNESCO’s World Natural Heritage sites. However, due to strong human pressures the region immediately surroundings the protected area has severely degraded. Aims of this thesis were to inventory carabid fauna in RNP and evaluate their use as indicators of the environmental change. Carabid beetles were collected from protected area (secondary and primary forests) and from its degraded surrounding area. Collecting was mostly conducted by hand during years 2000-2005. Species compositions between the protected area and its surroundings were compared, and species habitat preferences and seasonal variations were studied. In total, 4498 individuals representing 127 carabid species (of which 38 are new species) were collected. Species compositions within and outside of the protected area were markedly different. Most of the species preferred forest as their primary habitat and were mainly collected from trees and bushes. Their value as indicators is based on their different habitat requirements and sensitivity to environmental variables. Some of the species were found only in the protected forest, some occupied also the degraded forests and some preferred open areas. Carabid fauna is very species rich in Ranomafana and there are still many species to be found. Most of the species are arboreal and probably cannot survive in the deforested areas outside the park. This is very likely also the case for other species. Establishment and continued protection of RNP is probably the only way to conserve this globally important area. However, new occupations and land use methods are urgently needed by the local people for improving their own lives while maintaining the forest intact.

"Contesting Forests and Power; Dispute, Violence and Negotiations in Central Java" is an ethnographic analysis of an ongoing forest land dispute and its negotiations in an upland forest village in the district of Wonosobo, Central Java. Rather than focusing only on the village site, this ethnography of global connections explores the inequalities of power in different negotiation arenas and how these power relations have had an effect on the dispute and efforts made to settle it. Today, national and transnational connections have an effect on how land disputes develop. This study argues that different cosmological and cultural orientations influence how the dispute and its negotiations have evolved. It draws its theoretical framework from legal and political anthropology by looking at the position of law in society, exploring state formation processes and issues of power. The dispute over state forest land is about a struggle over sovereignty which involves violence on the parts of different parties who maintain that they have a legitimate right to the state forest land. This anthropological study argues that this dispute and its negotiations reflect the plurality of laws in Java and Indonesia in a complex way. It shows that this dispute over forests and land in Java has deep historical roots that were revealed as the conflict emerged. Understanding land disputes in Java is important because of the enormous potential for conflicts over land and other natural resources throughout Indonesia. After the fall of President Suharto in 1998, disputes over access to state forest land emerged as a problem all over upland Java. As the New Order came to an end, forest cover on state forest lands in the Wonosobo district was largely destroyed. Disputes over access to land and forests took another turn after the decentralization effort in 1999, suggesting that decentralization does not necessarily contribute to the protection of forests. The dispute examined here is not unique, but, rather, this study attempts to shed light on forest-related conflicts all around upland Indonesia and on the ways in which differential power relations are reflected in these conflicts and the negotiation processes meant to resolve them.

In recent decades, nation-states have become major stakeholders in nonhuman genetic resource networks as a result of several international treaties. The most important of these is the juridically binding international Convention on Biological Diversity (CBD), signed at the Rio Earth Summit in 1992 by some 150 nations. This convention was a watershed for the identification of global rights related to genetic resources in recognising the sovereign power of signatory nations over their natural resources. The contracting parties are legally obliged to identify their native genetic material and to take legislative, administrative, and/or policy measures to foster research on genetic resources. In this process of global bioprospecting in the name of biodiversity conservation, the world's nonhuman genetic material is to be indexed according to nation and nationality. This globally legitimated process of native genetic identification inscribes national identity into nature and flesh. As a consequence, this new form of potential national biowealth forms also what could be called novel nonhuman genetic nationhoods. These national corporealities are produced in tactical and strategic encounters of the political and the scientific, in new spaces crafted through technical and institutional innovation, and between the national reconfiguration of the natural and cultural as framed by international political agreements. This work follows the creation of national genetic resources in one of the biodiversity-poor countries of the North, Finland. The thesis is an ethnographic work addressing the calculation of life: practices of identifying, evaluating, and collecting nonhuman life in national genetic programmes. The core of the thesis is about observations made within the Finnish Genetic Resources Programmes in 2004 2008, gathered via multi-sited ethnography and related methods derived from the anthropology of science. The thesis explores the problematic relations of the communal forms of human and nonhuman life in an increasingly technoscientific contemporaneity the co-production and coexistence of human and nonhuman life in biopolitical formations called nations.

Nowadays any analysis of Russian economy is incomplete without taking into account the phenomenon of oligarchy. Russian oligarchs appeared after the fall of the Soviet Union and are represented by wealthy businessmen who control a huge part of natural resources enterprises and have a big political influence. Oligarchs’ shares in some natural resources industries reach even 70-80%. Their role in Russian economy is big without any doubts, however there has been very little economic analysis done. The aim of this work is to examine Russian oligarchy on micro and macro levels, its role in Russia’s transition and the possible positive and negative outcomes from this phenomenon. For this purpose the work presents two theoretical models. The first part of this thesis work examines the role of oligarchs on micro level, concentrating on the question whether the oligarchs can be more productive owners than other types of owners. To answer the question this part presents a model based on the article “Are oligarchs productive? Theory and evidence” by Y. Gorodnichenko and Y. Grygorenko. It is followed by empirical test based on the works of S. Guriev and A. Rachinsky. The model predicts oligarchs to invest more in the productivity of their enterprises and have higher returns on capital, therefore be more productive owners. According to the empirical test, oligarchs were found to outperform other types of owners, however it is not defined whether the productivity gains offset losses in tax revenue. The second part of the work concentrates on the role of oligarchy on macro level. More precisely, it examines the assumption that the depression after 1998 crises in Russia was caused by the oligarchs’ behavior. This part presents a theoretical model based on the article “A macroeconomic model of Russian transition: The role of oligarchic property rights” by S. Braguinsky and R. Myerson, where the special type of property rights is introduced. After the 1998 crises oligarchs started to invest all their resources abroad to protect themselves from political risks, which resulted in the long depression phase. The macroeconomic model shows, that better protection of property rights (smaller political risk) or/and higher outside investing could reduce the depression. Taking into account this result, the government policy can change the oligarchs’ behavior to be more beneficial for the Russian economy and make the transition faster.

Agriculture is an economic activity that heavily relies on the availability of natural resources. Through its role in food production agriculture is a major factor affecting public welfare and health, and its indirect contribution to gross domestic product and employment is significant. Agriculture also contributes to numerous ecosystem services through management of rural areas. However, the environmental impact of agriculture is considerable and reaches far beyond the agroecosystems. The questions related to farming for food production are, thus, manifold and of great public concern. Improving environmental performance of agriculture and sustainability of food production, sustainabilizing food production, calls for application of wide range of expertise knowledge. This study falls within the field of agro-ecology, with interphases to food systems and sustainability research and exploits the methods typical of industrial ecology. The research in these fields extends from multidisciplinary to interdisciplinary and transdisciplinary, a holistic approach being the key tenet. The methods of industrial ecology have been applied extensively to explore the interaction between human economic activity and resource use. Specifically, the material flow approach (MFA) has established its position through application of systematic environmental and economic accounting statistics. However, very few studies have applied MFA specifically to agriculture. The MFA approach was used in this thesis in such a context in Finland. The focus of this study is the ecological sustainability of primary production. The aim was to explore the possibilities of assessing ecological sustainability of agriculture by using two different approaches. In the first approach the MFA-methods from industrial ecology were applied to agriculture, whereas the other is based on the food consumption scenarios. The two approaches were used in order to capture some of the impacts of dietary changes and of changes in production mode on the environment. The methods were applied at levels ranging from national to sector and local levels. Through the supply-demand approach, the viewpoint changed between that of food production to that of food consumption. The main data sources were official statistics complemented with published research results and expertise appraisals. MFA approach was used to define the system boundaries, to quantify the material flows and to construct eco-efficiency indicators for agriculture. The results were further elaborated for an input-output model that was used to analyse the food flux in Finland and to determine its relationship to the economy-wide physical and monetary flows. The methods based on food consumption scenarios were applied at regional and local level for assessing feasibility and environmental impacts of relocalising food production. The approach was also used for quantification and source allocation of greenhouse gas (GHG) emissions of primary production. GHG assessment provided, thus, a means of crosschecking the results obtained by using the two different approaches. MFA data as such or expressed as eco-efficiency indicators, are useful in describing the overall development. However, the data are not sufficiently detailed for identifying the hot spots of environmental sustainability. Eco-efficiency indicators should not be bluntly used in environmental assessment: the carrying capacity of the nature, the potential exhaustion of non-renewable natural resources and the possible rebound effect need also to be accounted for when striving towards improved eco-efficiency. The input-output model is suitable for nationwide economy analyses and it shows the distribution of monetary and material flows among the various sectors. Environmental impact can be captured only at a very general level in terms of total material requirement, gaseous emissions, energy consumption and agricultural land use. Improving environmental performance of food production requires more detailed and more local information. The approach based on food consumption scenarios can be applied at regional or local scales. Based on various diet options the method accounts for the feasibility of re-localising food production and environmental impacts of such re-localisation in terms of nutrient balances, gaseous emissions, agricultural energy consumption, agricultural land use and diversity of crop cultivation. The approach is applicable anywhere, but the calculation parameters need to be adjusted so as to comply with the specific circumstances. The food consumption scenario approach, thus, pays attention to the variability of production circumstances, and may provide some environmental information that is locally relevant. The approaches based on the input-output model and on food consumption scenarios represent small steps towards more holistic systemic thinking. However, neither one alone nor the two together provide sufficient information for sustainabilizing food production. Environmental performance of food production should be assessed together with the other criteria of sustainable food provisioning. This requires evaluation and integration of research results from many different disciplines in the context of a specified geographic area. Foodshed area that comprises both the rural hinterlands of food production and the population centres of food consumption is suggested to represent a suitable areal extent for such research. Finding a balance between the various aspects of sustainability is a matter of optimal trade-off. The balance cannot be universally determined, but the assessment methods and the actual measures depend on what the bottlenecks of sustainability are in the area concerned. These have to be agreed upon among the actors of the area

The purpose of this study was to produce information on and practical recommendations for informed decision-making on and capacity building for sustainable forest management (SFM) and good forest governance. This was done within the overall global framework for sustainable development with special emphasis on the EU and African frameworks and on Southern Sudan and Ethiopia in particular. The case studies on Southern Sudan and Ethiopia focused on local, national and regional issues. Moreover, this study attempted to provide both theoretical and practical new insight. The aim was to build an overall theoretical framework and to study its key contents and main implications for SFM and good forest governance at all administration levels, for providing new tools for capacity building in natural resources management. The theoretical framework and research approach were based on the original research problem and the general and specific aims of the study. The key elements of the framework encompass sustainable development, global and EU governance, sustainable forest management (SFM), good forest governance, as well as international and EU law. The selected research approach comprised matrix-based assessment of international, regional (EU and Africa) and national (Southern Sudan and Ethiopia) policy and legal documents. The specific case study on Southern Sudan also involved interviews and group discussions with local community members and government officials. As a whole, this study attempted to link the global, regional, national and local levels in forest-sector development and especially to analyse how the international policy development in environmental and forestry issues is reflected in field-level progress towards SFM and good forest governance, for the specific cases of Southern Sudan and Ethiopia. The results on Southern Sudan focused on the existing situation and perceived needs in capacity building for SFM and good forest governance at all administration levels. Specifically, the results of the case study on Southern Sudan presented the current situation in selected villages in the northern parts of Renk County in Upper Nile State, and the implications of Multilateral Environmental Agreements (MEAs) and of the new forest policy framework for capacity building actions. The results on Ethiopia focused on training, extension, research, education and new curriculum development within higher education institutions and particularly at the Wondo Genet College of Forestry and Natural Resources (WGCF-NR), which administratively lies under Hawassa University. The results suggest that, for both cases studies, informed decision-making on and capacity building for SFM and good forest governance require comprehensive, long-term, cross-sectoral, coherent and consistent approaches within the dynamic and evolving overall global framework, including its multiple inter-linked levels. The specific priority development and focus areas comprised the establishment of SFM and good forest governance in accordance with the overall sustainable development priorities and with more focus on the international trade in forest products that are derived from sustainable and legal sources with an emphasis on effective forest law enforcement and governance at all levels. In Upper Nile State in Southern Sudan there were positive development signals such as the will of the local people to plant more multipurpose trees on farmlands and range lands as well as the recognition of the importance of forests and trees for sustainable rural development where food security is a key element. In addition, it was evident that the local communities studied in Southern Sudan also wanted to establish good governance systems through partnerships with all actors and through increased local responsibilities. The results also suggest that the implementation of MEAs at the local level in Southern Sudan requires mutually supportive and coherent approaches within the agreements as well as significantly more resources and financial and technical assistance for capacity building, training and extension. Finally, the findings confirm the importance of full utilization of the existing local governance and management systems and their traditional and customary knowledge and practices, and of new development partnerships with full participation of all stakeholders. The planned new forest law for Southern Sudan, based on an already existing new forest policy, is expected to recognize the roles of local-level actors, and it would thus obviously facilitate the achieving of sustainable forest management.

The indigenous cloud forests in the Taita Hills have suffered substantial degradation for several centuries due to agricultural expansion. Currently, only 1% of the original forested area remains preserved in this region. Furthermore, climate change imposes an imminent threat for local economy and environmental sustainability. In such circumstances, elaborating tools to conciliate socioeconomic growth and natural resources conservation is an enormous challenge. This dissertation tackles essential aspects for understanding the ongoing agricultural activities in the Taita Hills and their potential environmental consequences in the future. Initially, alternative methods were designed to improve our understanding of the ongoing agricultural activities. Namely, methods for agricultural survey planning and to estimate evapotranspiration were evaluated, taking into account a number of limitations regarding data and resources availability. Next, this dissertation evaluates how upcoming agricultural expansion, together with climate change, will affect the natural resources in the Taita Hills up to the year 2030. The driving forces of agricultural expansion in the region were identified as aiming to delineate future landscape scenarios and evaluate potential impacts from the soil and water conservation point of view. In order to investigate these issues and answer the research questions, this dissertation combined state of the art modelling tools with renowned statistical methods. The results indicate that, if current trends persist, agricultural areas will occupy roughly 60% of the study area by 2030. Although the simulated land use changes will certainly increase soil erosion figures, new croplands are likely to come up predominantly in the lowlands, which comprise areas with lower soil erosion potential. By 2030, rainfall erosivity is likely to increase during April and November due to climate change. Finally, this thesis addressed the potential impacts of agricultural expansion and climate changes on Irrigation Water Requirements (IWR), which is considered another major issue in the context of the relations between land use and climate. Although the simulations indicate that climate change will likely increase annual volumes of rainfall during the following decades, IWR will continue to increase due to agricultural expansion. By 2030, new cropland areas may cause an increase of approximately 40% in the annual volume of water necessary for irrigation.
