<p> The purpose of this study was to investigate the social, economic and technological factors that influence rates of adoption of innovative stormwater management approaches in municipal organizations in the Great Bay watershed, NH. The scope of this study was to investigate how innovations spread through municipal populations in a specific region and watershed area of the US. The methodology used mixed qualitative methods, including semi-structured interviews, case studies, and surveys to examine perceptions, attitudes, and beliefs that influence the adoption of innovative stormwater management solutions, as well as the governance characteristics of municipalities at different stages of adoption. Major findings include: adopter categories can be relatively easily and quickly categorized into early and late majorities as a preliminary means to identify populations of ready and willing audiences interested in and capable of advancing innovations; early and late adopter classifications followed general diffusion theory, but differed in substantial ways that could influence overall project or program success; and finally that early majority communities have more internal and external capacity to advance innovations as well as higher levels of peer-to-peer trust to offset perceptions related to economic risk that can either advance or stall innovative stormwater management solution adoption. This research offers insights on how to allocate scarce resources to optimally improve water quality through stormwater management solutions, and makes recommendations for how to effectively and efficiently generate greater understanding of complex barriers to adoption that thwart innovation in municipal governance organizations. One significant implication is that agents of change who want to move innovations through a broad municipal population should focus their efforts on working with innovators and early adopters that have status within relevant peer networks and who have capacity to evaluate the strengths and weaknesses of innovations.</p>

In the water utility sector, traditional asset management focusses on the maintenance and provision of physical assets (infrastructure) that allow water companies to deliver their services, meet their customers’ expectations and achieve their economic objectives. Nevertheless, the serviceability of the sector heavily depends on natural elements (e.g. rain, land). The importance of Natural Capital (i.e. the natural systems and their deriving ecosystem services) has been at the core of policy recommendations which have shaped regulatory changes in the water sector of England and Wales. Water companies are now required to explicitly account for and report their inter-dependencies on the natural environment and adopt systems-oriented approaches in their Asset Management Programmes (AMPs). These reforms will enable the sector to become resilient to the environmental and societal challenges faced at urban and rural contexts. Responding to the regulatory demands, the research introduces a novel and structured approach for integrating natural capital in the asset management portfolio of the water industry. The work is built on a transdisciplinary research framework and demonstrates that a new scale needs to be considered for the implementation of Holistic Asset Management: the water basin or catchment. A Catchment Metabolism modelling schema was created, grounded on the principles of Integrated Catchment Management and ecosystems services. The schema is based on the robust synthesis of concepts, tools and methods from a spectrum of disciplines. These include Industrial Ecology, Water Accounting, Environmental Regional Input-Output Analysis, hydrology, software engineering and functional modelling. Catchment Metabolism introduces a holistic perspective in asset management and expands its scope. The schema enables the conceptualisation, modelling and management of catchments as complex asset systems. It, thus, forms the ground for structured collaboration among experts for integrated water resources planning and decision-making. The schema allows for the design and implementation of catchment-based strategies and the assessment of their environmental performance. An industrial case study for a pilot catchment system (Poole Harbour Catchment) is used to demonstrate the application of the Catchment Metabolism. Alternative strategies for nitrogen pollution mitigation are assessed. The application of winter cover crops across the catchment appears to be the optimum strategy. The case study demonstrates the practical and modular implementation of the schema, reveals its methodological strengths and limitations and evaluates its applicability in the asset management planning and decision-making of the water sector.

O Estado do Cearà foi um dos pioneiros no cenÃrio nacional a estabelecer sua legislaÃÃo estadual, a Lei n 11.996/1992, atualizada pela Lei n 14.844/2010, que teve como base legal e institucional, a SRH e a COGERH, componentes do SIGERH, que implantou a gestÃo de Ãgua por bacias hidrogrÃficas, bem como, o modelo de gestÃo compartilhada, com foco na parceria entre Estado e Sociedade. Foi com o recorte na Bacia HidrogrÃfica do Rio Jaguaribe, mais pontualmente, nos ComitÃs das Sub-Bacias HidrogrÃficas do Baixo e do MÃdio Jaguaribe, que se pretende realizar uma anÃlise de forma comparativa das semelhanÃas e diferenÃas desses dois comitÃs. ConstituÃdos no mesmo perÃodo, porÃm apresentam diferenÃas perceptÃveis na forma de funcionamento, no nÃvel de participaÃÃo dos seus membros, nos encaminhamentos das reuniÃes e nas deliberaÃÃes, dentre outros. Tendo em vista essas diferenÃas que sÃo relevantes, este trabalho tem por objetivo realizar uma anÃlise da dinÃmica social destes comitÃs, investigando os seguintes aspectos: gerenciamento dos recursos hÃdricos nas bacias hidrogrÃficas; cobranÃa pelo uso da Ãgua; conflito pelo uso da Ãgua; participaÃÃo social e redes sociais. A metodologia utilizada trata de uma abordagem quanti/qualitativa, tendo como foco os colegiados, universo da pesquisa. Na conclusÃo do trabalho foi observado com relaÃÃo aos comitÃs, que apesar das diferenÃas que sempre existiram entre os mesmos, no olhar da pesquisadora, a dimensÃo dessas diferenÃas se apresentava de forma bem maior, uma impressÃo cristalizada. ApÃs a tabulaÃÃo dos dados, essas diferenÃas passaram a serem vistas de outra forma. Cada comità faz o seu prÃprio caminho, em alguns aspectos se encontram, em outros se divergem. Portanto, os comitÃs se encontraram quando apresentaram os seguintes pontos em comum: falta de apoio financeiro para a implantaÃÃo de projetos, que implica em uma maior autonomia; dificuldade das organizaÃÃes da sociedade civil para participar das reuniÃes dos comitÃs por falta de transporte (hoje està equilibrado); e divergiram em outros pontos como a distÃncia espacial entre os municÃpios da bacia, contrapondo as realidades do vale e da âÃrea secaâ, que tem interesses diferentes e a falta da cultura de participaÃÃo. / The state of Cearà was one of the pioneers on the national scene to establishits state legislation through the Law No. 11.996/1992, updated by Law No.14.844/2010, which had the legal and institutional basis, SRH and COGERH, SIGERH components, which implemented the water management by watershed, as well as the shared management model, focusing on the partnership between State and Society. The research had focused on the Jaguaribe Watershed, punctually, on the Committees of the Sub-Watershed of the Lower and Middle Jaguaribe, which aims to conduct a comparative analysis of the similarities and differences of these two Committees. They were made in the same period, but they have noticeable differences in operation, in the level of participation of its members in referrals and the deliberations of meetings, among others. Because of these differences that are relevant, this work aims to conduct an analysis of the social dynamics of these committees, investigating the following aspects: management of water resources in the watersheds; charging for water use; conflict over water use; social participation and social networks. The methodology is a quantitative / qualitative approach , focusing on the collegiate , the research universe . At the conclusion of the study it was observed, with regard to the Committees, that despite the differences that have always existed between them , in the eyes of the researcher , the magnitude of these differences is presented in a much larger form , a crystallized impression. After tabulating the data , these differences were regarded in another way . Each committee makes its own way: in some respects they are similar, in others they diverge . Therefore the Committees met when presented the following points in common : lack of financial support for the implementation of projects , which implies greater autonomy ; difficulty of civil society organizations to participate in committee meetings for lack of transport ( today is balanced) and differed on other points as the spatial distance between the municipalities of the watershed , contrasting the realities of the valley and the ' dry area' which has different interests , and the lack of a culture of participation.

O presente projeto de pesquisa levantou e analisou os dados de demandas para diversos usos em sub-bacias das quais Jacaré-Guaçu, Jacaré-Pepira e Rio Claro que fazem parte da UGRHI 13 (Bacia Hidrográfica Tietê-Jacaré) e que deságua no trecho médio do rio Tietê, no reservatório da Usina Hidrelétrica de Ibitinga. O objetivo desta pesquisa foi fornecer resultados baseados em critérios técnicos científicos para auxiliar no processo de direito de uso da água subsidiando assim o respectivo Comitê de Bacias Hidrográficas que compõem a região de estudo na determinação das vazões de outorgas requeridas. Os dados das demandas de abastecimento público, dessedentação (pecuária), irrigação, industrial, diluição de esgoto doméstico e diluição de esgoto industrial, bem como a demanda para geração de energia da UHE Ibitinga, subsidiaram a entrada de dados no programa de simulação computacional MIKE BASIN. O programa MIKE BASIN encontra-se disponível no Núcleo de Hidrometria do Centro de Recursos Hídricos e Ecologia Aplicada da Escola de Engenharia de São Carlos da Universidade de São Paulo, e é composto de um sistema de informações geográficas, um modelo de simulação quantitativo capaz de integrar técnicas de otimização, e um banco de dados georreferenciado. Com o software MIKE BASIN foi possível identificar as disponibilidades hídricas para atender diversos usos dos recursos hídricos diante das crescentes demandas e das diferentes condições hidrológicas, definindo assim um planejamento para os diferentes usuários da água, minimizando os conflitos entre os usos múltiplos desta e quantificando o grau de compromisso existente entre eles. Por fim, os resultados foram apresentados através de gráficos, tabelas que podem subsidiar o comitê de bacia, auxiliando no processo de planejamento e gestão dos usos dos recursos hídricos para diversos cenários futuros. / This research project examined the data and raised the demands for various uses in sub-basins of which Jacaré-Guaçu, Jacaré-Pepira and Claro river that are part of UGRHI 13 (watershed Tietê-Jacaré) and reaching the average sentence Tietê river, the reservoir of the hydroelectric plant Ibitinga. The objective of this research was to provide results based on scientific technical criteria to help in the right to use water as subsidizing the watershed committee of the component to the study region in determining the flow of grant requested. The data demands of the public supply, livestock, irrigation, industrial, dilution of domestic sewage and industrial sewage dilution, and the demand for energy generation of HPP Ibitinga, subsidized the entry of data in the computer simulation program, MIKE BASIN. MIKE BASIN program is available at the Center for Hydrometers the Center for Water Resources and Applied Ecology, School of Engineering of São Carlos, University of São Paulo, and is composed of a geographic information system, a simulation model capable of quantitatively integrate optimization techniques, and a georeferenced database. With the software MIKE BASIN was possible to identify the available water to meet various uses of water resources in the face of growing demands and the different hydrological conditions, thus defining a plan for the different users of water, minimizing conflicts between the multiple uses of and quantifying the degree of compromise between them. Finally, the results were presented through graphs, tables that can support the committee of basin, assisting in the planning process and management of the uses of water resources for various future scenarios.

¡§Zhou-Zai Wetland Park¡¨ is a specific prototype of created wetland ecosystems constructed in urban areas, This park represents integration between development and preservation of a wetland habitat through ecotechnology. It is a created wetland designed to conserve the endangered species of Jacanas in Taiwan, which were suffered from the destruction of habitat in the past. The wetland comprises pool and marsh types of wetland systems, and the inflow of the systems is pumped from the Lian-Chih Lake. Several problems were found when we operated and managed the park including eutrophication, low water exchange rate, and hypoxia in some water areas, emergence, and invasive alien species. The current management strategies are difficult to improve the status. Therefore some suggestions are given to solve such problems including constructing a treatment wetland in injection area in order to improve the water quality of influent and then provide a better water environment of habitat for water fowls as well as to prevent the intrusion of invasive alien species.
