Bridges Across Borders (BAB), a non-governmental organization (NGO) in Cambodia, directs diverse and complementary projects to improve the lives of Cambodians living in poverty. The Hand In Hand project (HIH) is one of these projects, implemented in the rural community of Chamcar Bei. This project started in 2006 and is designed to be completely sustained by the villagers after 5 years. One of the four components of HIH is a health component, whose goal is to improve the health of the community. In 2007 and 2008, through these health initiatives, BAB provided the community with 280 ceramic water filters, 20 wells and 10 latrines. BAB agreed to host an internship that would allow me to monitor and evaluate these water and sanitation initiatives. My internship responsibilities included providing advice on future Monitoring and Evaluation (ME) protocols as well as community and organizational identified indicators to gauge the progress of the initiatives. In addition, these protocols were to be gender sensitive and able to be sustained by the community. For the internship I conducted ethnographic interviews with members of BAB and with members of the community regarding the water initiatives objectives, potential impacts as well as guidance on future initiatives and ME protocols, including indicators to gauge programmatic progress. Cultural explanatory models of disease, traditional therapies and gendered nuances related to water procurement and management were also explored to inform program development. Focus groups and 90 household surveys were used to triangulate data. Findings revealed that organization and community perceived benefits of the technologies, while not in complete congruence, did overlap, allowing for the recommendation of mutually informed ME indicators. In addition, both the community and organization identified salient program and ME issues and proffered solutions. Community ownership and education were not integral components of past initiatives. This compromised sustainability and the community's commitment as well as belief in their ability to care for the technologies. However, the motivation of some community members to acquire ME skills and recognition by the organization of past programmatic errors have paved the way for future community driven, informed and sustained ME protocols.

Les Objectifs de Développement Durable visent d'ici 2030 un « accès pour tous à des services d'assainissement et d'hygiène adéquats, en mettant fin à la défécation à l'air libre ». Un service d'assainissement peut-être défini par ses composantes techniques et sociales, et leurs interactions. Dans l'optique de proposer des pistes d'améliorations des services d'assainissement en zone tropicale, les travaux de cette thèse ont porté à la fois sur des infrastructures de traitement et sur l'implication de l'ensemble des acteurs dans la définition du service. L'analyse croisée des contextes des départements d'outre-mer (DOM) français et du Sénégal a permis d'identifier des contraintes qui pèsent sur le secteur de l'assainissement en zone tropicale. Du point de vue des infrastructures de traitement, ces contraintes nous ont amenées à proposer des procédés issus de la famille des Filtres Plantés de Végétaux (FPV) comme solutions à priori pertinentes. Cette thèse présente leurs adaptations à la zone tropicale, en détaillant les choix retenus pour le dimensionnement, la conception des filtres et le choix des végétaux. Une centaine de campagnes de suivi ont été réalisées sur 7 stations pilotes en tailles réelles, à travers les 5 DOM. Les résultats montrent que malgré une plus grande compacité, le dimensionnement proposé permet de conserver des niveaux de traitement au moins comparables à ceux observés en climat tempéré. Compte tenu des contraintes climatiques et organisationnelles en milieu tropical, une analyse de leur résilience à des perturbations et de leur fiabilité de traitement a été réalisée par une étude statistique sur les données produites par l'autosurveillance réglementaire. Elle montre que les FPV sont également plus fiables que les procédés de traitement conventionnel les plus répandus pour les petites collectivités. Ce qui s'explique à la fois par la barrière physique que représente ces procédés de cultures fixées sur support fin ainsi que par des besoins en entretien plus réduits. Le deuxième axe de recherche part du constat d'un manque de concertation entre acteurs au moment de la planification de l'assainissement, étape qui préside à la construction du système d'assainissement. En particulier, les utilisateurs, leurs besoins et leurs contraintes sont très peu et mal pris en compte. La modélisation d'accompagnement pourrait permettre de créer à la fois un support (le modèle) permettant de discuter des choix techniques et de leurs conséquences, ainsi que le cadre dans lequel les différents acteurs pourraient échanger leurs points de vue et trouver un consensus soutenable. Un processus de modélisation d'accompagnement a été conçu et mis en place sur la planification de l'assainissement dans 2 zones (urbaine et rurale) du Sénégal. Il nécessitait, pour proposer des scénarios viables, d'intégrer une part non négligeable de connaissances expertes. Centré sur les populations, ce processus a permis la création d'un premier modèle générique sur l'accès à l'assainissement qui prend la forme d'un jeu de rôle. La pertinence de tels outils dans la caractérisation des besoins des usagers a été évaluée. Par ailleurs, l'attention a été portée sur l'acceptation par les usagers du service proposé et sa traduction en volonté de contribution / Sustainable Develoment Goals aim by 2030, to « achieve access to adequate and equitable sanitation and hygiene for all and end open defecation », by « using safely managed sanitation services ». Sanitation service can be defined by its technical and social components, and their interactions. This thesis focuses on both treatment infrastructures and involvement of all the stakeholders into service definition. Cross analysis of French Overseas Territories (FOT) and Senegal contexts, has identified common constraints that weigh on sanitation sector in tropical areas. From treatment infrastructure point of view, these constraints lead to suggest treatment wetlands systems and particularly French vertical-flow treatment wetland (FS-VFTW) to easier sludge managment, as a relevant solution. Their adaptation for tropical climate is the subjet of the first axis of our work. It aimed at defining their adaptation in terms of design, plant choices and defining the treatment wetlands type to implement according to outlet requirements. A hundred of 24h sampling campains were performed on 7 full scale demonstration plants, accross the 5 FOTs. Results show that despite more compacity, the proposed design allows maintaining performances at least similar to those observed in temperate climate. Due to climatic and organizational constraints inn tropical climate, a statistical analysis has been done to point out the resilience and reliability of the systems based on regulatory selfmonitoring data. It highlights the fact that FS-VFTWs are more reliable than most of the conventional treatment processes when applied for small size communities. Their physical barrier (filter) and their lower maintenance requirement explain this observation. The second axis of our research is based on an observed lack of consultation between stakeholders during the sanitation planning phase, which is responsible for the construction of the sanitation system. In particular, the users, their needs and their constraints are poorly and badly taken into account. Companion modeling approach could create both a support (the model) for discussing technical choices, as well as the framework within which the stakeholders could exchange points of view and find a sustainable consensus. Such a process has been developed and implemented for sanitation planning in 2 areas (urban and rural) of Senegal. Focused on household population, this process has led to create a generic model for sanitation access, embodied as a role playing game, which include a significant part of expert knowledge. The relevance of such tools in the characterization of user needs has been evaluated. In addition, attention was paid to users' acceptance of the proposed service and its translation into a willingness to contribute

Philosophiae Doctor - PhD (School of Public Health) / Poor water, sanitation and hygiene (WASH) services and practices in communities are known to be responsible for most of the infections occurring among infants and young children in developing countries. A combined effect of disease, poor diet, care practices and other factors among infants/children are known to lead to undernutrition reported in most developing countries. Apart from the reduced growth and productivity potential that malnutrition exhibits on the affected population, it is also an underlying cause to 50% of child mortality in poor communities. In light of this, the primary objective of the study was to evaluate the effect of poor WASH practices on growth and infectious disease incidence in infants and young children aged 6-23 months in the rural district of Monze in Zambia.

Der Abwassersektor in Deutschland sieht sich mit zunehmend turbulentem Umfeld konfrontiert. Auf Grund der langen Nutzungsdauer ihrer Infrastruktur und ihrer Kapitalintensität ist die Abwasserwirtschaft durch hohe Fixkosten und durch ihre Anfälligkeit gegenüber Pfadabhängigkeiten charakterisiert. Dies zeigt sich besonders im Zusammenhang mit den Auswirkungen des demografischen Wandels in den letzten Jahren, in Folge dessen abnehmende Bevölkerungszahlen zu einem Verlust von Gebührenzahlern geführt haben. Zusätzlich wurde dieser Effekt durch einen beträchtlichen Rückgang der Wassernachfrage pro Kopf verstärkt. Die herkömmlichen Planungsansätze in der Siedlungsentwässerung basieren hauptsächlich auf Prognosen und Trendfortschreibungen und berücksichtigen somit nur unzureichend sich ändernde Rahmenbedingungen. Aus diesem Grund untersucht diese Dissertation inwiefern die geringe Anpassungsfähigkeit, die im Zusammenhang mit dem demografischen Wandel offensichtlich wurde, durch eine Stärkung der strategischen Planungskompetenzen, und speziell durch die Anwendung der Szenarioplanung, erhöht werden kann. Hierfür werden sowohl die prediktiven als auch die explorative Möglichkeiten der Szenarioplanung bewertet. Im ersten prediktiven Ansatz liegt der Fokus auf den spezifischen Auswirkungen des demografischen Wandels auf die Abwassergebühren. Der zweite explorative Ansatz basiert auf einer Kombination der Delphi-Technik mit der Szenarioplanung, in der die bedeutendsten zukünftigen Herausforderungen identifiziert und in vier Szenarien zusammengefasst werden.:1 FRAMEWORK OF THE CUMULATIVE DISSERTATION 7 2 JOURNAL ARTICLE I1: SZENARIOPLANUNG 23 3 JOURNAL ARTICLE I2: SZENARIOPLANUNG IM INTEGRIERTEN WASSERRESSOURCENMANAGMENT 27 4 JOURNAL ARTICLE P1: DER DEMOGRAFISCHE WANDEL ALS GEBÜHRENTREIBER IN DER SIEDLUNGSENTWÄSSERUNG 35 5 JOURNAL ARTICLE E1: NACHHALTIGE UNTERNEHMENSFÜHRUNG MIT DER DELPHI-METHODE 47 6 JOURNAL ARTICLE E2: REVIEW OF DELPHI-BASED SCENARIO STUDIES 51 7 JOURNAL ARTICLE E3: SCENARIOS FOR THE SANITATION SECTOR: A DELPHI-BASED APPROACH 67 8 CONCLUDING REMARKS 107 / The sanitation sector in Germany is challenged by an increasingly turbulent environment. Due to the long use-life of the infrastructure and its capital intensity, the sector is characterized by low rates of return, high fixed-costs and vulnerability to path dependency. This became particularly obvious in the last years within the context of demographic change, when a decreasing population led to the loss of fee payers, and was intensified by a considerable decline in the water demand per capita, which caused increasing wastewater fees. The traditional planning instruments in the sanitation sector rely mainly on forecasts and forward projections, while disregarding key dynamics of the surrounding political-legal, economic, societal, technological and environmental framework conditions. Therefore, this dissertation assesses if the low adaptive capacity of the sanitation sector, which became obvious with demographic change, can be enhanced by strengthening the long range planning competencies by means of scenario planning. The dissertation evaluates the possibilities of scenario planning as alternative planning instrument and explores the predictive as well as the explorative possibilities in two separate research streams. The predictive research stream analyzes the specific impacts of demographic change on wastewater fees. The focus lies on a short time horizon and one specific trend. The latter explorative research stream is addressed by a Delphi-based scenario study, in which the most relevant future challenges of the sanitation sector are identified and summarized in four scenarios.:1 FRAMEWORK OF THE CUMULATIVE DISSERTATION 7 2 JOURNAL ARTICLE I1: SZENARIOPLANUNG 23 3 JOURNAL ARTICLE I2: SZENARIOPLANUNG IM INTEGRIERTEN WASSERRESSOURCENMANAGMENT 27 4 JOURNAL ARTICLE P1: DER DEMOGRAFISCHE WANDEL ALS GEBÜHRENTREIBER IN DER SIEDLUNGSENTWÄSSERUNG 35 5 JOURNAL ARTICLE E1: NACHHALTIGE UNTERNEHMENSFÜHRUNG MIT DER DELPHI-METHODE 47 6 JOURNAL ARTICLE E2: REVIEW OF DELPHI-BASED SCENARIO STUDIES 51 7 JOURNAL ARTICLE E3: SCENARIOS FOR THE SANITATION SECTOR: A DELPHI-BASED APPROACH 67 8 CONCLUDING REMARKS 107

The objective of this research is to identify the need for stricter environmental standards and regulations in three areas of study. Organized by their level of analysis, these areas are Latin America (at the System-Level-of Analysis), Colombia (at the State-Level-of-Analysis), and the city of Cartagena (at the Sub-National-Level of Analysis). This research was accomplished in two phases. The first involved conducting an exhaustive literature search of sources, germane to the objective, published in Spanish and English. The second featured a site inspection conducted over a 10-day period during the month of May 2016 to Cartagena, Colombia. The purpose of the site inspection was to interview locals and to photographically document waste disposal practices. The results of this research determined that government at all levels (system, state, and subnational) play a significant and sometimes determinant role in managing waste and water pollution that are responsible for health problems primarily among the poor; these health problems are discussed in detail. This research discovered that the lack of government intervention is responsible for reducing the efficacy of waste management and water sanitation services. This research concludes with a discussion of how proactive waste management and water sanitation policies and practices can have a significant benefit not only to improving health but also has significant economic, social and environmental benefits that may reach beyond local levels.

Although the International Drinking Water Supply and Sanitation Decade has generated great interest from foreign aid donors, its impact. in terms of increased service levels has been poor. These disappointing results have been explained by the UN and other donors in terms of inadequate funding and lack of cost recovery, poor operations and maintenance, lack of personnel, unacceptable technology, poor logistics and non involvement of the beneficiaries. However, an alternative explanation revolves around factors contributing to poor project design. These include the lack of understanding of the development process, donor bias and self interest, and poor coordination and commitment by the recipient government. A review of the development and trends of contemporary aid philosophy and its translation in to rural development and water and sanitation projects, which led to the launch of the IDWSSD, provides a number of lessons that can be used to formulate a hybrid model for project design and the sector development process, that defines the relative roles of donors, recipient governments and people themselves. The model is based on coordinated development, community participation, and sector growth from pilot projects to large scale programmes. The developments in the rural water and sanitation sector that took place in Zimbabwe from 1974 to 1987, provide a unique opportunity to test this model using a systems analysis approach. After gaining Independence in 1980, Zimbabwe's development assistance funding grew tenfold with the influx of foreign donors, and major commitments were made by the new Government to rural development and the goals of the IDWSSD. However, the large investments in water and sanitation which included the preparation of a national master plan with external technical assistance, had both positive and negative impacts on the continuing development of the sector, the start of which can be traced back, well before Independence, to small pilot projects sponsored by non government organizations that used appropriate technology developed by the Rhodesian Government. This development process and the changing approach to project design is illustrated by a series of case studies of projects supported by multilateral and bilateral donors, and non government organizations, that were milestones during this period. Finally the project and sector development model is modified based on the practical lessons from Zimbabwe and recommendations for future practice are made together with suggestions for areas of further research.

Access to safe water and improved sanitation remains threatened by the ever increasing demand in urbanised cities of the world. Adequate management of this problem could not be achieved through technical and regulatory methods alone. A human values-based education approach, namely the Human Values Water, Sanitation and Hygiene Education (HVWSHE) programme, was considered a suitable intervention strategy to bring about the desired changes in attitude and behaviour by the water users. This research involves an empirical case study approach that explores the experiences of Laotian teachers as adult learners of the HVWSHE intervention as well as a literature study on adult education, adult learning facilitation, human values-based education and teacher beliefs. Focus group meetings, lesson observations, participant observation, field notes and a researcher journal was used to collect data. This study revealed that the HVWSHE training programme had a positive effect on the adult learners’ attitude and behaviour towards a better water-use and sanitation-friendly ethic. / Educational Studies / M.
