A liquid-to-air membrane energy exchanger (LAMEE) is a novel flat-plate membrane-based energy exchanger where heat and moisture transfer between air and solution streams occurs through a semi-permeable membrane. The LAMEE consists of many air and solution flow channels, each separated by a membrane. A small-scale single-panel LAMEE consists of a single pair of neighboring air and solution channels. This PhD thesis focuses on developing, testing and modeling the small-scale single-panel LAMEE, and investigating the similarity between the small-scale LAMEE and a full-scale LAMEE. This PhD thesis presents a methodology to investigate similarity between small-scale and full-scale energy exchangers. A single-panel energy exchanger test (SPEET) facility is developed and built to measure the performance of the small-scale single-panel LAMEE under different test conditions. Also, the small-scale LAMEE is numerically modeled by solving coupled heat and mass transfer equations for the air, solution and membrane of the LAMEE. The effects of membrane vapor diffusion resistance and enhanced air side convective heat transfer coefficient are numerically investigated. The numerical model of the small-scale LAMEE is validated with the experimental data for summer test conditions, and effectiveness values agree within ±4% in most cases. Moreover, the effects of different heat and mass transfer directions, and salt solution types and concentrations are experimentally and numerically investigated. The results show that the LAMEE effectiveness is strongly affected by the heat and mass transfer directions but negligibly affected by salt solution type and concentration. The solution-side effectiveness for liquid-to-air membrane energy exchangers is introduced in this thesis for the first time. The results show that the solution-side effectiveness should be used to evaluate the sensible and total effectiveness of LAMEE regenerators. Finally, the similarity between the small-scale and full-scale LAMEEs is investigated experimentally and numerically. The results show that the small-scale LAMEE effectiveness results can be used to predict the performance of a full-scale LAMEE within ±2% to ±4% in most cases.

<p>This thesis interrogates the claim that resource-poor, rural land seekers can acquire land through the land market which constitutes the central mechanism of land redistribution in South Africa&rsquo / s market-based land reform programme. The study explores two key aspects in relation to this claim. Firstly, it provides a critique of the underlying assumptions prevalent in much of the current market-based land reform policy, as advocated by its national and international proponents, and the manner in which the market as a mechanism for land redistribution has been conceptualized and its outcomes envisaged. Secondly, it considers the extent to which this conceptualization - which it is argued, draws on idealized and abstracted notions of land market functioning - is realized and examines the extent to which the espoused outcomes of market-based land reform policy are aligned with or contradicted by the functioning of real markets and the experiences of resource-poor land seeking people in their attempts to engage in the land market with limited state support. The details of the market&rsquo / s operation are analysed, with a distinction made between the operational practice of real markets &ndash / based on direct evidence-based observation <br /> and degrees of policy abstraction and theoretical assumptions regarding how markets should or might operate. The study&rsquo / s methodological framework draws on an agrarian political economy perspective, as used by theorists such as Akram-Lodhi (2007) and Courville (2005), amongst others. This perspective enables a consideration of the various contexts and socially embedded processes involved in land transactions and the extent to which these are shaped and framed by the politics of policy-making. In line with this perspective, the study focuses on the social relations brought to bear on the acquisition of land and the way in which land markets operate. It is suggested that land is not solely viewed as an economic commodity by land-seekers. Furthermore, it was found that markets cannot be understood as neutral institutions in which participants are equal players.</p>

This thesis comprises three essays on “The Economic impact of adult mortality and morbidity on smallholder farm households in Malawi.” The first essay estimates the levels of technical efficiency of AIDS-affected and non-affected smallholder farm households, and examines the technical efficiency differentials. The study uses time-varying and timeinvariant inefficiency models of production. The results show that among both female and male headed households, for both affected and non-affected households, fertilizer and seeds are the only variables that contribute significantly towards technical efficiency. The mean efficiency levels of affected and non-affected households are statistically not different. The second essay examines the maize production differentials between AIDS-affected and nonaffected farm households using the difference in difference estimation method. The results show that, for both affected and non-affected households, the mean maize production levels are higher during 2006/07 compared to 2004/05 However, the difference between the mean maize production levels of affected and non-affected households over the 2004/05 and 2006/07 period is not statistically significant. The third essay examines the coping strategies used by households facing food security problems. The results from the multinomial logistic model show that during 2004/05 and 2006/07, the most dominant coping strategy used by both AIDS-affected and non-affected households facing food security problems, is buying food from market. This is followed by casual labour, obtaining food from relatives and friends, eating unripe maize before harvest, and irrigation farming. The results from logistic discriminant analysis function indicate that, for all households, ordinary coping strategies are dominant among food-insecure households with a total score of close to 80 percent, much higher than survival strategies at around 20 percent during 2004/05. / Thesis (Ph.D.)-University of KwaZulu-Natal, Westville, 2011.

Single Desk Seller (SDS) firm structures dominate the agribusiness sector in many developing countries, and were created to resolve export market failure and achieve performance efficiency and effectiveness. Many of these SDSs are also state owned enterprises and have been perceived to be inefficient and a drain on the public purse, as well as no longer having a raison d'être in the face of the World Trade Organization’s anti-competition open markets policies. However, unlike in developed countries, SDSs are likely to remain a significant feature in small developing countries due to their inherent problem of small scale and undeveloped equity markets. It therefore beholds researchers and practitioners to correct inefficiencies of these structures in order to achieve optimal performance. The Arrowroot Industry Association, with a record of disastrous performance makes an ideal case to explore this governance-performance relationship. A holistic case study research methodology was used to carry out this study The main finding was that the governance structure of the Arrowroot Industry Association (AIA) was unresponsive to and did not co-evolve with its environment over the last (20) twenty years. As a result it increasingly became an inefficient mechanism for solving governance according to the normative prescriptions of property rights, transactions cost, agency, resource based view, resource dependency theories, stakeholder, and stewardship theories. Consequently, and despite having a rare and valuable starch product, the AIA was unable to meet demand or secure sufficient rents from the value chain to meet the revenue objectives of itself or of its members. The most significant causes of inertia in the AIA’s strategy and structure were caused by two exogenous variables (a fixed legislation and significant politically influence in the strategic process), and two endogenous variables (poor cognitive ability of management and directors and the limiting effects of its eroded resource base). The combination of poor performance and inertia of the AIA over the years resulted in various forms of escalating commitments, debt accumulation and a shrinking supply base upstream as producers sought alternative means of income. Furthermore, the absence of markets for managerial talents, corporate control and arrowroot production, harvesting and processing technologies restricted alternatives available to the AIA of Government in resolving the perceived problems. Research implications and recommendations for the AIA are subsequently discussed. The major recommendations proposed to reverse the performance problem of the AIA were (1) tighter vertical integration of the AIA to internalise of downstream inefficiencies, (2) efficient allocation of property rights along the entire value chain, (3) clearly defined roles and boundaries for key stakeholders, (4) increasing managerial, technological and financial capacity, and (5) reducing Government control by making influence-cost significantly prohibitive.

Based on recent estimates, the average demand for wood at 1.39 m3/year/capita surpasses the average annual allowable cut at 0.95 m3/year/capita. The annual wood supply deficit in Tanzania is estimated to be 19.5 million m3. Underlying causes for the wood supply gap include: weak value chains that undermine market access, unsustainable wood production, and harvesting practices. Policies targeted at strengthening the institutional capacity of the forestry sector at local and national levels are suggested to increase the share contribution of the sector to the national economy. To foster small-scale wood production, government needs to expedite efforts in tenure security, and make financial services, extension services, and market information accessible to farmers. Continuous collaboration between the government and actors in the wood value chain is crucial. This policy brief is intended for forest and natural-resource policymakers, wood industrial sector, non-governmental organizations, and academia dealing with the forestry and wood sector in Tanzania.:Key Messages: Page 1 Prevailing challenges: Page 2 Project methods: Page 2 National wood scenarios: Page 3 Wood value chain: Page 4 Policy actions and recommendations to achieve a sustainably wood supply: Page 5 Contact: Page 6

Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: Small-scale farmers have the opportunity to gain access to markets through a contract farming arrangement. The key question is whether it is financially feasible for a small-scale farmer to enter into a contract. The objectives of this study were to develop a model that could be used to determine the financial feasibility of small-scale contract broiler farming in an intensive production system, compare three different genotypes namely: Cobb500 males X Hybro G females, Ross 308 males X Potchefstroom Koekoek females (crossbred) and the purebred Potchefstroom Koekoek, and evaluate current smallscale farmers’ broiler production by means of a case study. Financial performance indicators such as the net present value, cash flow and profit and loss statements were used to analyze the feasibility of all the scenarios. The model was built in Microsoft Excel. Five hundred, 1500 and 2500 birds/cycle scale of production were analyzed. Results revealed that based on the capital costs used, a 500 birds/cycle scale of production was uneconomical and that a farmer would have to receive R25.01/kg broiler meat in order to break even. The 1500 scale of production showed much better results. A farmer could break even at R17.51/kg meat. The capital investment cost of the 2500 scale of production was so high that the farmer would have had to sell his broiler meat for R18.54/kg. Performance traits of genotypes were collected through an experiment and data was statistically analyzed using ‘Statistica 9’. Results showed that there were significant differences between the cumulative feed intake, feed conversion ratios and the European production efficiency ratio of the different genotypes. No significant difference was found in the liveability of the genotypes. Data on performance traits was used as input into the model so that the economic feasibility of the genotypes could be compared. Results showed that a purebred Potchefstroom Koekoek genotype was not suitable for an intensive production system and that the crossbreed did not perform as well as the broiler breed, but that it would be worthwhile investigating the performance traits of the cross breed under less optimal conditions or in a free-range system. The lower capital costs necessary for a freerange system, together with the high premium paid for free-range broiler meat, may give admirable results in the economic feasibility of a small-scale broiler farm. / AFRIKAANSE OPSOMMING: Kleinboere het die geleentheid om deur kontrak boerdery toegang tot markte te verkry. Die vraag is egter of dit finansieël haalbaar is vir 'n kleinboer om kontraktueel verbind te word? Die doelwitte van die studie was om: ‘n model te ontwikkel wat gebruik kan word om die finansiële lewensvatbaarheid van' n klein-skaalse braaikuikenboer te bepaal onder 'n intensiewe produksiestelsel; verskillende genotipes naamlik: Cobb500 hane X Hybro G henne, Ross 308 hane X Potchefstroom Koekoek henne (kruising) en die suiwer Potchefstroom Koekoek te evalueer en die die huidige klein-skaal boer se braaikuikenproduksie deur middel van 'n gevallestudie te evalueer. Finansiële prestasie aanwysers soos die netto huidige waarde, kontantvloei, asook wins en verlies state was gebruik om die haalbaarheid van die verskeie gevalle te analiseer. Die model is op Microsoft Excel gebou. ‘n Produksie skaal van 500, 1500 en 2500 kuikens/siklus is ontleed. Resultate het getoon dat, gebaseer op die kapitale koste wat gebruik is, 'n produksie skaal van 500 kuikens/siklus onekonomies is en dat ʼn boer R25.01/kg sal moet ontvang om gelyk te breek. Die produksie skaal van 1500 kuikens/siklus het beter resultate getoon. 'n Boer kan gelyk breek teen R17.51/kg vleis. Die kapitale beleggingskoste van die produksie skaal van 2500 kuikens/siklus was so hoog dat die boer R18.54/kg sou moes ontvang het om gelyk te breek. Prestasie van genotipes is ingesamel deur middel van 'n eksperiment en data is statisties ontleed met behulp van Statistica 9. Resultate het getoon dat daar hoogs beduidende verskille tussen die kumulatiewe voerinname, voeromsetsverhoudings en Europese produksie effektiwiteits verhouding van die verskillende genotipes is. Geen beduidende verskil is gevind in die leefbaarheid van die genotipes nie. Inligting oor die prestasie eienskappe is gebruik as insette tot die model sodat die ekonomiese haalbaarheid van die genotipes vergelyk kon word. Resultate het getoon dat 'n suiwer Potchefstroom Koekoek genotipe nie geskik is vir 'n intensiewe produksie stelsel nie en dat die kruising nie so goed soos die braaikuiken gevaar het nie, maar dat dit die moeite werd sal wees om ondersoek in te stel na die produksie potensiaal van die kruis kuiken in minder optimale toestande, soos ‘n vryloop stelsel. Die laer kapitale koste en die hoë premie wat betaal word vir vryloop braaikuikenvleis mag geloofwaardige resultate op die ekonomiese haalbaarheid van 'n kleinskaalse braaikuikenboer toon.

In today’s working life both the physical and the psychosocial aspects has to be considered when examining the work environment. The psychosocial working environment is of great relevance because it illuminates the individual's perception and experience of relationships and phenomena at work. This essay aims to investigate, describe and analyze the obligation an employer has to pursue in order to tackle high short- term sickness absence and at the same time manage the psychosocial work environment at the workplace. Furthermore, the purpose of this study is to acknowledge the European legislation on this subject matter in order to broaden the understanding of the comprehensiveness of the term psychosocial work environment and how applicable laws and guidelines apply in working life. The legal methodology has been used in order to answer the questions of this essay. The social perspective worked as a complement to the legal method in order to observe new problems and conduct more information in how to confront this issue at small scale enterprises. In conclusion this study deals with a complex situation where every case is unique. It is not possible to prevent all short-term sickness absence, but with the right preconditions and external assistance, employers can handle it without neglecting the psychosocial work environment. By securing a good psychosocial work environment even the smallest enterprises might be able to handle short- term sickness absence.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta pesquisa tem por objetivo analisar os conflitos socioambientais envolvendo os pescadores artesanais na Baía de Ilha Grande e as iniciativas institucionais que buscam dar tratamento a esses conflitos de forma compartilhada. Neste sentido, foram consideradas duas iniciativas institucionais: i) o Projeto Desenvolvimento e Gerenciamento dos Sistemas de Gestão da Pesca e Aquicultura na baía de Ilha Grande GPESCA-BIG; e ii) o Termo de Compromisso entre a Estação Ecológica de Tamoios e as comunidades pesqueiras de Angra dos Reis e Paraty. A metodologia envolveu a observação direta da autora em reuniões de conselhos consultivos e grupos de trabalho em unidades de conservação, em especial, os espaços envolvendo a Estação Ecológica de Tamoios, além de apresentações e audiências públicas sobre a proposta de Acordos de Pesca. Utilizou-se também a observação participante em reuniões e oficinas no âmbito do projeto GPESCA-BIG. De forma complementar, a pesquisa se baseou em entrevistas (formais e informais) e análise de documentos diversos elaborados por entidades representativas dos pescadores e demais atores direta e indiretamente envolvidos no conflito. Foram identificadas três grandes grupos de conflitos relacionados aos pescadores artesanais: (1) sobreposição de territórios de pesca/pesqueiros e as áreas protegidas, principalmente aqueles relacionados à ESEC Tamoios; (2) conflitos associados à pesca industrial, identificados pelos pescadores como barcos de fora, e em menor escala, as embarcações de petróleo/gás e do turismo e; (3) conflitos resultantes da falta de regularização/permissionamento da atividade. Em síntese, estes conflitos envolvem políticas de desenvolvimento e de conservação, que se confrontam com o modo de vida tradicional dos pescadores artesanais e caiçaras. Além dos conflitos oriundos das diferentes formas de apropriação do espaço marinho, estes conflitos também estiveram relacionados ao papel paradoxal do Estado no estabelecimento das regras e normas de ordenamento (incluindo-se a fiscalização/monitoramento ambiental), à burocracia e às diversas instituições existentes para tratar de problemas comuns, tornado confuso o gerenciamento da atividade. No que se refere às iniciativas em análise, os resultados demonstram a existência de instituições relativamente bem constituídas na região, com a atuação de órgãos de gestão pública e ambiental nos mais variados níveis: municipal estadual e federal. Além destes, registra-se também a participação da sociedade civil, em especial, dos pescadores artesanais de Paraty e de suas representações, na busca pelo tratamento dos conflitos nos quais estão inseridos. Por outro lado, evidencia-se a falta de articulação e integração entre as políticas e atores, bem como entre as experiências institucionais em curso. Portanto, um dos maiores desafios existentes na implantação de um modo compartilhado de gestão dos recursos pesqueiros na BIG consiste justamente em superar tais limitações institucionais, de maneira que possam promover ações articuladas visando não apenas a conservação integrada do ecossistema, como também a reprodução das práticas tradicionais de pesca e a sua co-existência com os demais tipos de usos / This thesis analyses environmental conflicts involving artisanal fishermen in the Ilha Grande Bay and institutional initiatives aiming at managing such conflicts in shared manners. Two initiatives were considered: i) the project Development of Management Systems of Fisheries and Aquaculture in Ilha Grande Bay GPESCA-BIG; and ii) The Commiment Term between the Tamoios Ecological Station and fishermen communities of Angra dos Reis and Paraty. The methodology comprised the authors direct observation in meetings of the consultation councils and working groups in conservation units, in special, those involving the Tamoios Ecological Station, and also participation in presentations about the proposition of Fishing Agreements and other public hearings. The research also used participative observation in meetings and workshops within the GPESCA-BIG project. Additionally, formal and informal interviews were carried on with relevant actors, and varied documents by entities such as Fishermen Associations, City Governments and City Councils, Ministry of Fisheries and Aquaculture and the Ministry of Environment were consulted. Three major groups of fisheries-related conflicts were identified: (1) overlapping between fishing and protected areas; (2) conflicts associated with large-scale fishing and, to a smaller degree, with oil and gas ships and touristic boats; and (3) conflicts due to the lack of regularization/allowance of the activity. In sum, these conflicts involve both development and conservation policies, which at all times contradict the traditional lifestyle of artisanal fishermen and caiçaras. Besides resulting from different forms of use of the sea, these conflicts are also related to the paradoxical role of the State in setting rules (including supervision and environmental monitoring) to the bureaucracy and to several institutions dedicated to common problems. Regarding the initiatives under analysis, results show that there are relatively well established institutions in the region, comprising public environmental agencies at local, state and national levels. One can also mention the participation of civil society, in special, artisanal fishermen from Paraty and their associations. On the other hand, it is worth highlighting the lack of integration among such policies and agencies/actors, as well as among institutional experiences under way. Therefore, one of the major challenges in the implementation of a strategy of co-management of fishing resources in the Ilha Grande Bay consists in overcoming such institutional shortcomings and adopting articulated initiatives aimed not only at the conservation of the environment, but also the sustainability of traditional fisheries and their co-existence with other kinds of use of the marine resources

Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems. Understanding the different sustainability dimensions and trade-offs between assessment indicators can support the planning of sustainable on-site sanitation systems for a specific context. The overall aim of this thesis was to evaluate the sustainability and function of on-site sanitation systems by defining a set of indicators to assess on-site sanitation options and estimating them for different scenarios, and by investigating the treatment efficiency of on-site facilities for domestic wastewater treatment in a field study. Particular attention was given to the removal of phosphorus (P) and indicator bacteria due to their relevance in terms of eutrophication risk and public-health concern. In a multi-criteria approach, twelve indicators were defined to assess nine on-site sanitation systems. A reference group representing stakeholders’ views assigned weights to express the relative importance of each indicator. The reference group assigned the highest weights to the indicators robustness, risk of pathogen discharge and nutrient removal. Assessing the robustness proved to be challenging, as there is a gap between how the sanitation systems are expected to perform based on their design, and how they actually perform in practice, mainly due to incorrect construction, operation and maintenance. The discriminating power of the indicators was calculated using the entropy method, which showed that the indicators energy recovery and capital cost had little impact in the final ranking of the alternatives. A sustainability ranking was obtained by using the method ELECTRE III. A scenario analysis based on different settings of interest based on socio-economic and geographical factors was done to evaluate the changes in the ranking of alternatives. Overall, the greywater–blackwater separation system ranked the highest in the baseline scenario and when nutrient-related indicators were important (Scenario 2), together with the urine diversion system. The sand filter and drain field were the most sustainable options when nutrient removal and recycling was not important (Scenario 1), and (in combination with chemical P-removal) when the indicators related to energy and climate change had the highest weights (Scenario 3). In terms of P-removal, chemical removal outranked the alkaline P-filter. In a field study, the effluent wastewater from twelve on-site wastewater treatment facilities with sand and alkaline P-filters was evaluated in terms of removal and discharge of organic content, total and dissolved phosphorus, and indicator bacteria (E. coli, total coliforms, intestinal enterococci and C.perfringens). The results showed that the investigated sand filters generally had low P-removal capacity and sometimes exceeded the criteria for excellent water quality set by the EU bathing water directive with regard to intestinal enterococci and E. coli. Only one sand filter of eight was confirmed to remove P according to the Swedish guidelines for areas with non-sensitive receiving waters with a tot-P effluent concentration below 3 mg L−1. This indicates that a downstream treatment step is needed to meet the guidelines regarding P discharge concentrations. Alkaline P-filters generally removed P efficiently. Despite high effluent pH, the collected data did not generally confirm a further reduction of the bacterial content of the wastewater in the P-filters, as had been previously hypothesized. However, effluent concentrations of indicator bacteria showed moderate positive correlations with effluent concentrations of P and organic matter, indicating the potential of the P-filters to serve as a polishing step also for bacteria. / Små lokala avloppssystem för insamling och rening av avloppsvatten är vanligt förekommande i omvandlings- och landsbygdsområden i många länder. Dessa system fungerar ofta sämre än förväntat vilket kan leda till effekter på recipienter, ökad risk för folkhälsan och begränsa systemens hållbarhet. En djupare förståelse för hållbarhetsdimensioner och avvägningar mellan olika indikatorer kan stödja planering och implementering av hållbara lokala avloppsystem för specifika sammanhang. Det övergripande syftet med denna uppsats var att utvärdera hållbarhet och funktion av enskilda avloppssystem. Detta utfördes genom att först definiera en uppsättning indikatorer för bedömning av ett antal enskilda avloppsalternativ och sedan utvärdera dem för olika scenarier. Vidare var syftet att undersöka några systems prestanda för rening av hushållsavloppsvatten i en fältstudie. Särskilt fokus lades på reduktion av fosfor (P) och indikatorbakterier på grund av deras relevans i relation till övergödningsrisk och folkhälsoperspektiv. I en multikriteriestudie definierades tolv indikatorer för att bedöma nio typer av enskilda avloppssystem. En referensgrupp som representerade olika intressenter viktade indikatorerna för att uttrycka den relativa betydelsen av varje indikator. Referensgruppen gav systemens robusthet, risk för utsläpp av patogener, och näringsreduktion störst vikt. Att bedöma robusthet var en utmaning i studien, eftersom det finns ett gap mellan hur systemen förväntas fungera, och hur de faktiskt fungerar i praktiken, mestadels på grund av felaktig konstruktion, drift och underhåll. Indikatorernas diskriminerande effekt räknades ut med entropimetoden, som visade att indikatorerna energiåtervinning och kapitalkostnad hade liten inverkan på alternativens slutgiltiga rangordning. En scenarioanalys genomfördes baserad på socioekonomiska och geografiska faktorer. En hållbarhetsrankning erhölls genom att använda ELECTRE III-metoden. Överlag rankades system som separerar gråvatten – svartvatten samt urinseparerande system högst i basfallsscenariot och när näringsrelaterade indikatorer var viktiga (scenario 2). Markbäddar och infiltrationsanläggningar var de mest hållbara alternativen när rening och återvinning av näringsämnen inte var viktigt (scenario 1) och (i kombination med kemisk P-rening) när indikatorer relaterade till energi och klimatförändringar viktades högst (scenario 3). När det gäller P-rening, gav system med kemisk rening ett bättre utfall än de med alkaliska P-filter. I en fältstudie utvärderades tolv enskilda avloppsanläggningar med markbaserade system och alkaliska P-filter med avseende på rening och utsläpp av organiskt innehåll, totalt och löst P och indikatorbakterier (E.coli, totala koliformer, intestinala enterokocker och C.perfringens). Resultaten visade att de markbaserade systemen generellt hade låg P-reningskapacitet och ofta överskreds kriterierna för utmärkt vattenkvalitet enligt EUs badvattendirektiv avseende intestinala enterokocker och C. perfringens. Endast ett markbaserat system av åtta uppvisade en P-rening som låg under de svenska riktlinjerna för områden med normal skyddsnivå, med en utsläppskoncentration på under 3 mg L-1 tot-P. Detta indikerade att markbäddar behöver nedströms placerade reningssteg för att uppfylla nuvarande riktlinjer för utsläpp av P. Alkaliska P-filter avskilde generellt P effektivt. Trots högt pH-värde kunde ingen ytterligare minskning av bakterieinnehåll i avloppsvattnet från P-filtren påvisas statistiskt. Utsläppen av indikatorbakterier uppvisade emellertid måttliga positiva korrelationer med utsläpp av P och organiskt material, vilket visar på en viss potential att P-filtren kan fungera som ett ytterligare poleringssteg även för bakterier.

Cairu, único município arquipélago do Brasil, está situado no litoral leste da Bahia, formado por 26 ilhas, três das quais (Tinharé, Boipeba e Cairu) abrigam as 13 localidades, dentre elas Gamboa, Garapuá, Moreré e São Sebastião, onde foi realizado o trabalho de campo. Os resultados da pesquisa confirmaram a perspectiva teórica de que relação entre o rural e o urbano configuram a dinâmica contemporânea do município, demostrando a importância que tem as populações destas localidades e seus modos de vida no contexto municipal, compondo um espaço complexo. A pesquisa amplia as discussões sobre a atividade pesqueira contribuindo para a compreensão da tessitura das sociedades que possuem uma relação direta com a natureza em suas práticas sociais e econômicas / This research demonstrates the interaction between the lifestyles of fishermen and the contemporary dynamics of the city Cairu in Bahia and its outlook in the existing development project. The city of Cairu, the only archipelago municipality of Brazil, is located on the east coast of Bahia. It has 26 islands, three of which (Tinharé, Boipeba and Cairu) contain 13 localities, among them Gamboa, Garapuá, Moreré and São Sebastião, where the field work was preformed. The survey results confirm the theoretical perspective that the relationship between rural and urban areas shapes the contemporary dynamics of the city, showing the importance of the populations of these places and their ways of living in the municipal context, forming a complex space. The research extends the discussions about the contribution of fishing to the understanding of the fabric of societies that have a direct relationship with nature in their social and economic practices
