This thesis focuses on the evaluation of the current state of common facilities and the following draft of comprehensive land consolidation in the cadastral territory of Dolní and Prostřední Svince. In the scope of the common facilities, the survey focused on the network of roads/paths and subsequently its elaboration in the form of a digital map. After the survey of the followed territories in the terrain the current state was processed which showed the individual advantages and disadvantages. By means of the evaluating criteria the effectiveness of the common facilities within comprehensive land consolidation for zones of interest was tested. The target of the performed evaluation and the draft of measures is the total improvement and strengthening of effectiveness of individual common facilities within comprehensive land consolidation.

This diploma thesis is divided into two main parts. The first part describes issues of the proposal of water management measures in land consolidation process. Second part deals with the conceptual proposal of water management measures in the specific cadastral area. This part also include graphic attachments.

Textil- och beklädnadsindustrin har expanderat kraftigt sedan 1990-talet och är idag en av de största industrierna i världen. Den globala försörjningskedjan inom industrin innefattar komplexa nätverk och förhållanden kring bland annat sourcingstrategier och var företag väljer att placera sin textilproduktion. För att skapa konkurrenskraftiga strategier krävs kontroll av företagens produktion- och leveranskedja, och allt fler företag har insett att offshoring inte är lönsamt. Sourcingstrategin nearshoring, vilket innebär att företag placerar produktionen närmare hemlandet och företagets huvudsakliga marknad, har istället blivit allt mer intressant. Tidigare forskning kring sourcingstrategierna offshoring och nearshoring fokuserar på hur implementering av strategierna kan ser ut, och vilka möjligheter och utmaningar det innebär. Det saknas däremot forskning kring hur textil- och modeföretag bemöter och hanterar dessa utmaningar. Denna uppsats syftar därmed till att studera drivkrafter bakom svenska textil- och modeföretags val av sourcingstrategi, samt hur företagen hanterar utmaningar för att upprätthålla en effektiv och lönsam försörjningskedja. Som hjälpmedel för att identifiera drivkrafter och strategiska hanteringsåtgärder, används Supply Chain Management och det teoretiska perspektivet Resource-based view. Studien är kvalitativ och materialinsamlingen utgörs av semistrukturerade intervjuer med kompletterande observationer av fem svenska textil- och modeföretag. Intervjuerna har transkriberats, och tillsammans med observationerna har en tematisk analys genomförts. Studiens resultat efter materialinsamlingen visar på att drivkrafter och utmaningar bakom företags val av sourcingstrategi har en koppling till hantering och effektivitet av försörjningskedjan. Studien visar även på att svenska textil- och modeföretag är intresserade av nearshoring, och vill implementera det i framtiden, men att vissa utmaningar är för stora för att hantera på ett lönsamt sätt. Svenska textil- och modeföretag har olika motiv för varför de väljer olika sourcingstrategier, och det innebär att företagen anpassar sina sourcingstrategier efter deras tillgångar och resurser. Studiens slutsats är att företag upplever drivkrafter och utmaningar med både offshoring och nearshoring, och att en kombination av dessa kan vara möjligt att tillämpa. Studien är applicerbar inom textilt management eftersom resultatet kan hjälpa svenska textil- och modeföretag att jämföra de olika sourcingstrategier för att därmed skapa strategiska beslut kring sourcing och val av leverantörer. / Since the dawn of the 1990s the textile and clothing industry has expanded rapidly, becoming one of the largest industries in the world. The global supply chain that enables the clothing industry requires complex networks and methods regarding, among other things, sourcing strategies and where companies choose to locate their textile production. In order to create more competitive strategies a company requires control of its production and supply chain so that they can change it to maximize profit, and recently actors within the industry have realized that offshoring is no longer as profitable. The sourcing strategy nearshoring, when companies choose to locate production closer to the home country and the company's main market, has instead become increasingly attractive. Previous research surrounding offshoring and nearshoring focus on what the implementation of these strategies can look like as well as what opportunities and challenges these strategies present. However, there is a lack of research on how textile and fashion companies respond to and manage these challenges. This essay therefore aims to study the driving forces behind Swedish textile and fashion companies´ choice of sourcing strategies, as well as how the companies deal with events that challenge the maintaining of an efficient and profitable supply chain. Supply Chain Management and the theoretical perspective Resource-based view are used as tools to identify the driving forces behind strategic management measures. This study is qualitative and the material collected comes from semi-structured interviews, with supplementary observations, of five Swedish textile and fashion companies. The interviews have been transcribed, and together with the observations, a thematic analysis has been carried out. The study's results show that the driving forces and reasoning deciding companies' choice of sourcing strategy has a connection to Supply Chain Management. The results also suggest that Swedish textile and fashion companies are interested in nearshoring, and want to implement it in the future, but the challenges are too great to handle in a profitable way. Swedish textile and fashion companies have different motives for why they choose different sourcing strategies, and this means that the companies adapt their sourcing strategies according to their assets and resources. The study's conclusion is that companies experience driving forces and challenges with both offshoring and nearshoring, and that a combination of the two strategies may be possible to apply. The study is relevant for textile management strategizing because the results can help Swedish clothing and textile companies to compare different sourcing strategies in order to make strategic decisions regarding sourcing and the choice of suppliers. This essay is written in Swedish.

Temporary closures of octopus fishing areas constitute a promising co-management measure that aims to improve local governance, food security and incomes in coastal small-scale fishing communities. Although positive social and economic outcomes of temporary closures are increasingly reported, the underlying social-ecological and ecological interactions, and their impact on closure benefits are rarely studied. This lack of systemic understanding may lead to undesired outcomes. Here, I extend an existing agent-based model of temporary closures to explore the influence of individual octopus movements on ecological outcomes and fishers’ benefits in Zanzibar. First, I conceptualized the octopus closure system by analyzing empirical qualitative data and literature. Next, I iteratively developed and tested an individual-based model extension. This extension simulates between-den movements across a hypothetical seascape and formalizes intrinsic attributes of Octopus cyanea such as movement patterns and maturity stages. I analyzed the effects of varying closure size of fishing grounds temporarily closed to illustrate potential implications for outcomes of octopus closures. Simulation results show that individual octopus movements triggered by fishing activities have noticeable impacts on octopus sizes, their spatial and temporal distribution, and fishers’ catches, particularly when considering different social groups that depend on the fishery. Scenarios with closures in place show higher mean octopus weight in closed areas in contrast to open-access areas. Mean catches for women foot-fishers are lower compared to freedivers’ catches and even slightly lower when allowing octopuses to move in response to disturbance in all scenarios. Catch rates and distribution of mature octopuses are highly sensitive to closure size revealing a social-ecological trade-off when implementing larger closures. This study demonstrates an approach to integrating individual octopus movements and interactions between fishers and octopuses in a fishery management context, and suggests that reactive movement of octopus contributes to unequal distribution of the closure benefits between different social groups. / Octopus and People In Novel Transdisciplinary Simulations (OctoPINTS project)

Natürliche Niederungsgebiete wirken als effektive Phosphor Senke. Landwirtschaftliche Nutzung und Drainage führt zur Transformation zu Phosphor Quellen. Dem Spreewald, ein Feuchtgebiet und seiner Funktionsweise als Phosphor Quelle oder –Senke, kommt im Einzugsgebiet der Spree eine wichtige Rolle zu. Die vorhandenen Kenntnisse der Phosphor Umsatzprozesse und des Phosphor Austausches zwischen den Flächen und dem Fließgewässernetz sind jedoch gering. Praktikable Ansätze zur Beschreibung des Phosphor Austauschverhaltens von Nährstoffen in den ausgedehnten Polderregionen liegen nicht vor. Anhand hydrologischer, geohydraulischer und biogeochemischer Prozessuntersuchungen in einer Polderlandschaft mit typischer Stauhaltung konnten die Phosphor Freisetzungs- und Retentionsprozesse ausgewiesen werden. Unter Nutzung verschiedener Modellansätze (geohydraulische Modellierung, Stofftransportmodellierung und Statistische Modelle) und der Berechnung von Phosphor Prozessraten werden horizontale und vertikale Phosphor Fluxe in den Flächen-Wasser Übergangszonen quantifiziert. Die Ergebnisse gehen in ein Phosphor Bilanzmodell ein, das die P-Quellen und Senkenfunktion von Polder Teilflächen (überstaut, genutzt) und des gesamten Polders in Monatsschritten abbildet. Die biogeochemischen Phosphor Umsatzprozesse sowie der horizontale und vertikale Transport werden wesentlich von den hydrologischen und den klimatischen Bedingungen gesteuert. Sie stellen die primären Einflussgrößen der P Senken oder -Quellenfunktion dar. Im Polder wird die Phosphor Netto Freisetzung der genutzten Bereiche durch eine hohe Phosphor Netto Retention in den überstauten Flächen abgemindert. Szenario Untersuchungen zeigen, dass sinkende Grabenwasserstände zu einer erheblichen Erhöhung der Phosphor Emissionen aus dem Grundwasserpfad führen. Ansteigende Phosphor Fluxe bei sinkenden Wasserständen legen ein zunehmendes Eutrophierungsrisiko in den Gräben sowie für unterhalb gelegene aquatische Systeme nahe. / Natural wetlands effectively retain phosphorus. Agricultural cultivation and drainage by ditches transform them to phosphorus sources. In the Spree catchment, the Spreewald, a large scaled lowland has a strategic importance operating as a phosphorus sink or phosphorus source. Anyhow, knowledge of its phosphorus turnover processes and the phosphorus exchange behavior between the plain and the river and ditch network are marginal. Practicable approaches to reproduce the phosphorus exchange behavior in its typical polder areas are missing. Based on process investigations in a polder area with typical weir regulation, phosphorus retention and remobilization processes are characterized. Combining different model approaches (groundwater modeling, matter transport modeling and statistical models) and calculating process rates, the horizontal and vertical phosphor fluxes in the water soil/sediment transition zones are quantified. The outcomes are used as input data for a phosphorus balance model reproducing the phosphorus source and sink character of used and rewetted polder areas and for the whole polder in monthly time steps. Results from process and transport investigations point out that biogeochemical turnover processes and horizontal or vertical phosphorus transport are driven by hydrological and climatological conditions. Net phosphorus release found in the extensive used polder areas is counteracted by significant net phosphorus retention in the rewetted parts. Scenario analyses identify decreasing ditch water levels to cause a considerable increase of phosphorus emissions from the groundwater pathway. Consequently, the increasing phosphorus fluxes at decreasing water levels provoke a growing risk for eutrophication in the ditches but also in the downstream aquatic systems.

There is solved the cooperation of the land plan and complex land consolidation fot three different cadastral areas - Krtely, Malovičky and Podeřiště. These cadastral areas come under the administration of the community Malovice. The complex land consolidation and land plan were initiated in different order nad in defferent years. The land consolidatin for the cadastral area Krtely was initiated in 1992, for Malovičky in 2005 and for Podeřiště in 2007. Moreover, each project has been prepared by the different design office. The result of the diploma thesis is the assessment of the cooperation during different conditions and also the assessment of the processing quality of single projects.
