Background: Agriculture is among the relevant factors for the formation of cities and it has been an integral part of city life throughout history. Despite the increase in population growth, urban agriculture can offer a unique opportunity for improving the livelihood of individuals through the practice of growing food in urban green spaces. Nevertheless, maintaining urban green spaces as part of the urban fabric presents a unique challenge in an environment where there is a shortage of housing and urban space is limited for development. Allotment gardens might be seen as compensation for the lack of green space and private gardens in cities, especially in dense urban areas. However, due to the long waiting list for renting out, not everyone can get access to growing locally cultivated food and other benefits, especially people who are less privileged and cannot afford private gardens. Objective: The aim of this thesis, therefore, was to design a proposal for urban green space, Ekebydalen, to show how to integrate allotment gardening with other social activities. Also, as an input to the proposal, the history of allotment gardens and the theory of sustainable wellbeing was reviewed, and local public participation was investigated. Method: Literature was extensively reviewed in an attempt to identify relevant studies and better understand the context and characteristics of allotment gardens from a social and environmental context, the change in its land use, and accessibility; all in the perspective of the general development of urban agriculture and specifically in allotment movement through history in Sweden. Moreover, Site observation was conducted in a purposely selected allotment garden, Ekebydalen, Uppsala city. Also, an online and paper-based self-administered cross-sectional survey was done among 40 participants. Result: 6 different allotment gardens were observed and characterized. Based on the case study (observation), the Ekebydalen allotment garden was chosen as the main site for further pro-posal development. (60%) of the respondents in the survey were middle-aged (30 -50 years old) women (77.5%), most of them with university education (88%) and Swedish background (90%). Despite the participants has reported living in close proximity to the gardens, around a fourth of them reported having waited for more than six months. Gardening and nature interest (100%), socializing (15%), food complement (62%), and maintaining wellbeing (65%) are the motivation for renting allotment gardens. Conclusion: This thesis argues that the economic and wellbeing values of allotment gardens are perceived as highly significant compared to the social benefit that is allegedly seen less. Nevertheless, the social value can be seen as equally important if integrated as an activity with other social activities in a city, especially in urban communities that don't have enough space for gardening and are caught in their busy lives. Moreover, a design strategy was proposed to show how the allotment garden can be integrated as an activity for cultivation and recreation use (Cultivation park). This thesis has also implied that policy support, institutional recognition, and strong political will from policymakers and planners are required to bring urban agriculture into city planning for improving the quality of life for the people living and working in cities.

With continued pressure on biodiversity and ever-growing conflicts with human development, qualified systems for scenario modelling, impact assessment and decision support are urgently needed. Such systems must be able to integrate complex models and information from many sources and do so in a flexible and transparent way. To that end, as well as for other complicated and data-intensive biodiversity research purposes, the concept of LifeWatch has emerged. The idea of LifeWatch is to construct e-infrastructure and virtual laboratories by integrating large data sources, computational capacities, and tools for analysis and modelling in an open, serviceoriented architecture. To be efficient and accurate, a continuous inflow of large quantities of data is essential. However, even with new techniques, government-funded monitoring data and research data will not feed the system with up-to-date species information of sufficient scale and resolution. To fill this void, skilled amateur observers (citizen scientists) can contribute to a very valuable extent. After a preparatory phase, a Swedish LifeWatch (SLW) consortium was initiated in 2011. Swedish LifeWatch developed an infrastructure where all components are accessible through open web services. At the SLW Analysis portal, different formats of species and environmental data can be accessed instantly, and integrated, analysed, visualized and downloaded at selected temporal, spatial or taxonomic scales. Swedish LifeWatch currently provides 46 million species observations from eight different databases, all harmonized according to standardized formats and the Dyntaxa taxonomic backbone database. Almost 40 million of these observations were provided by citizens through the online reporting system named the Species Observation System (SOS) or Artportalen. This paper describes this system, as well as the incentives that make it so successful. The citizen science data in the SOS are accessible, together with data from research and monitoring, in the SLW infrastructure, making the latter a powerful instrument for large-scale data extraction, visualization and analysis.

Along with the technics that allows archaeology to adopt a precise knowledge about the composition of the materiality, also exists a critical thought that claims for take into account experience, perception and creativity. In the latter, we find Art-Archaeology approach. With this at background emerged the idea of the presence and the ontology of the 'dot' in archaeology, identified in the ongoing process of the attendance of a meeting at Kyoto, in the excavation of a simulated site, in the survey of an unidentified site and in a short research about Prehistoric tattoo. This idea, in its explicit simplicity, is part of a creative thought situated in the roots of the archaeological practice. In this paper I reflect about this through an artistic photo-essay that is at the same time an artistic and theoretical exercise, with the intention to identify the existence of the 'dot' in different dimensions of archaeology, and to make theory making art.

Payments for Ecosystem Services (PES) are widespread in conservation policy. In PES, environmental effectiveness and social equity are often perceived as conflicting goals. Empirical studies on the relationship between popular design features, such as payment differentiation and payment conditionality, and effectiveness and equity are scarce. Further, they struggle with measuring and separating ecological and equity outcomes. In this study, we combine two incentivized lab-in-the-field experiments with 259 land users from eight villages in North-Western Vietnam to assess both individual conservation effort and community-level equity perceptions under four different PES designs. Effort is measured in a real-effort task with real-world environmental benefits; equity perceptions about payment designs in the real-effort task are measured in a coordination game. We demonstrate that payment design affects both effort and equity perceptions. Payments which are differentiated and are solely conditional on individuals' contributions of effort are perceived as most equitable. They are also more effective in motivating conservation effort than other designs, although the differences are small and not significant for all comparisons. By working out the positive correlation of effectiveness and equity across the four payment schemes, we show that these objectives are not necessarily conflicting goals in incentive-based conservation policy. Further, we can show that women exert greater conservation efforts. We discuss how greater equity and effectiveness could be achieved with reforms towards more input-based distribution criteria in Vietnam's PES legislation and the limitations and opportunities of the experimental paradigm for research on PES.

This thesis examines the question of organization, governance and choice of seeds in Swedish agriculture. It consists of four papers: Paper I investigates the evolution of plant breeding industry in Sweden. The results suggest that the establishment of intellectual property rights (IPRs) schemes creates power in the seed value chain in Sweden and has therefore been a major driver of mergers and acquisitions, together with changes in domestic agricultural policy as well the country´s entrance to EU. Based on nationwide survey among farmers, papers II and III examine the impact of IPRs and specifically the implications of the enforcement of Plant Breeders Rights on farmers´ choice between certified versus farm saved seed (FSS). Paper II uses transaction cost theory and logistics regression to examine empirically the governance structure of farmers choosing certified or FSS. Farmers´ assessment of the quality seed in terms of the genetic purity of each channel has no impact on their choice while personal relations with their upstream partners, investments in the farm as well as delivery contracts affect their procurement strategy. In paper III, spatial autoregressive models are used in order to analyze the transfer of "know-how" between farmers, and the spillover effects of social learning in farmers´ choice of seed channel. Farmers are distinguished between neighbors, based on their relative distance; and peers, based on membership in farmers' cooperatives. The results indicate the existence of spatial dependence on Swedish farmers' choice of seed channel. Paper IV evaluates the impact of farmers' social networks on their decision to be involved in the governance of the agricultural cooperative. The findings suggest a relationship between network characteristics and farmers' involvement in the governance that persists over a long period.

In a world of permanent change, traditional language teaching methods do not solve the communicative needs in foreign languages ​​that favor knowledge and adaptation to changing educational contexts. The CLIL method is widely used to develop skills both in the learning language and in other areas of knowledge, it allows for the strengthening of teaching capacities to assume the teaching of contents of the different subjects in a foreign language. The objective of this bibliographic review is to collect significant and existing information on the CLIL method and contribution of this method in the educational field. The documentary descriptive approach of recent research related to the subject of study is used, based on the theoretical foundations of bilingual education. The literature review shows that by teaching the foreign language as a vehicle to instruct content from other subjects, students understand the need to learn the language to seize the knowledge of the subject and allows teachers to explore their own teaching context, reflect and identify factors that can improve their teaching practice, especially in the inclusion of writing activities in English.

Considers the possibility of using the Internet as an arena for political deliberation. The Internet provides user anonymity, a feature that can be used & refined to force the participants in a discussion to focus on content & ideas rather than the sender. The systematic use of democratic avatars -- a user-identity that protects the physical identity of the sender but at the same time reveals all messages that the user has sent -- would purify the deliberation & allow dissentient opinions to be expressed without fear, while at the same time forcing the participants to be open & consistent in their argumentation.
