Die Landwirtschaft ist heute der wichtigste Treiber der globalen Degradation von Ökosystemen. Es existiert jedoch wenig konkretes Wissen, wie Ökosysteme zu schützen sind und gleichzeitig die Nahrungsproduktion für die wachsende Weltbevölkerung gesichert werden kann. In dieser Dissertation untersuche ich Optimierungsmöglichkeiten im landwirtschaftlichen Wassermanagement. Ich quantifiziere praxisorientierte Verbesserungen der Regenwassernutzung und Optimierungen von Bewässerungssystemen, unter Einhaltung der „environmental flow requirements“ (EFRs). Um diese komplexen Interaktionen zu untersuchen, entwickle ich ein agro-hydrologisches Modell auf Basis detaillierter, mechanistischer Prozessabbildung weiter. Erstens, 39% der derzeitigen Wasserentnahmen für Bewässerung sind nicht nachhaltig und somit auf Kosten der Ökosysteme. Zweitens, solche lokalen Wasserentnahmegrenzen legen nahe, dass die globale Grenze für den menschlichen Wasserverbrauch deutlich niedriger liegt, als bisher angenommen (2800 vs 4000 km3yr-1). Drittens, die Implementierung von EFRs würde die landwirtschaftliche Produktion erheblich beeinträchtigen, mit >20% in stark bewässerten Gebieten. Verbesserte Nutzung des Niederschlagswassers und die Optimierung von Bewässerungssystemen, können die weltweite Nahrungsmittelproduktion allerdings um rund 40% nachhaltig steigern - ausreichend, um die Nahrungsmittellücke der wachsenden Weltbevölkerung bis 2050 zu halbieren. Zusammenfassend stellt diese Arbeit die erste umfassende und systematische Einschätzung globaler Potentiale der nachhaltigen Intensivierung der Landwirtschaft aus der Wasserperspektive dar. Die in dieser Arbeit vorgebrachten innovativen und quantitativen Erkenntnisse legen nahe, dass das Potential der diskutierten Interventionen höhere politische Aufmerksamkeit erfahren sollte. Meine Ergebnisse können eine konkretere Diskussion zur Umsetzung der Sustainable Development Goals untermauern. / Agriculture is today''s most important driver of ecosystem degradation across scales. However, there is little evidence on how to attain the historic twin-challenge of maintaining environmental integrity while producing enough food for a growing world population. In this thesis, I assess opportunities in agricultural water management to reconcile future food needs with environmental limits to water use. I explore solution-oriented ways to improve rainfed and irrigation systems alike, while safeguarding environmental flows (EFRs). To study complex interactions quantitatively, I advanced a state-of-the-art global modeling framework based on detailed, mechanistic process representation. First, a systematic upscaling of EFRs to global coverage indicates that 39% of current freshwater withdrawals for irrigation are unsustainable and occur at the cost of ecosystems. Second, accounting for EFRs indicates that the planetary boundary for freshwater use might be notably lower (2800 vs. 4000 km3yr-1) than expected. Third, maintaining EFRs would significantly affect food production, cutting >20% of total kcal production across intensely irrigated areas. Fourth, improving irrigation systems in combination with optimizing the use of precipitation water, provides effective and accessible measures to compensate for adverse impacts from protecting EFRs and climate change. Such integrated interventions could sustainably intensify global food production (+40% kcal) to the degree sufficient to halve the global food gap by 2050. In conclusion, this thesis provides the first comprehensive and systematic assessment of hitherto largely unquantified water opportunities in sustainable intensification of agriculture. While requiring corroboration by finer-scale research, the innovative quantitative foundation provided in this thesis suggests that farm water management merits a rise in political attention, and it can inform a more comprehensive discussion of related SDG target interactions.

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

Background: Ever since the Brundtland Commission stressed that Social Sustainability (SS) issues are often ignored, there has been mounting research on social sustainability (Boström, Vifell, Klintman, Soneryd, Hallström & Thedvall, 2015). Companies are now addressing sustainability concerns more broadly because of the increasing demand and pressure from society demanding they deal with the negative social impacts associated with their products and activities. This study is delimited to SMEs. While individual SMEs are naturally smaller and have less impact on sustainability than larger businesses, their involvement is important in achieving national SS targets (Weingaertner & Moberg, 2011). Sustainability is often regarded as the privilege of large corporations since they have sufficient funds to improve their carbon footprint (Rodgers, 2010). The activities of SMEs are not well understood and documented, including their entrepreneurial start-ups within communities, of which some are entirely based on sustainable principles (Rodgers, 2010). Given that SMEs play an important role towards sustainable development, understanding the underlying mechanisms of why SMEs are committed to SS within communities is an important research topic. Purpose: The purpose of this study is to investigate how SMEs facilitate the ability of communities to develop socially sustainable practices that not only satisfy the requirements of current members but also support the ability of future generations to maintain sustainable communities. Method: Due to the limited literature in social sustainability in the context of SMEs embedded in diverse communities, this thesis employs an exploratory research design together with qualitative and abductive approaches. Qualitative content analysis is used in coding and analysing the empirical findings, and the abductive approach is used in developing an extended framework of social sustainability. Conclusion: The aim of this study was to gain insight into the initiatives implemented by SMEs towards socially sustainable communities and the obstacles they face. Through qualitative research in different sectors of the economy (agriculture, construction, service, retail, manufacturing) and different countries, an empirical understanding of how SMEs engage in social sustainability initiatives was derived. The empirical findings resulted in the extension of a social sustainability framework proposed by Eizenberg and Jabareen (2017). In the extended framework, community social capital was added as the fifth concept of SS and its main components include human capital, social capital, social cohesion, social inclusion, natural capital and philanthropic capital. The variety of sectors and countries enabled us to take into account contextual differences and develop an international view of social sustainability concepts relevant for communities. / Bakgrund: Ända sedan Brundtland kommissionen betonade att SS-frågor ofta ignorerades, har det förekommit forskning om social hållbarhet (Boström, Vifell, Klintman, Soneryd, Hallström & Thedvall, 2015). Företagen är nu pressade att ta itu med sociala hållbarhetsfrågor och denna studie fokuserar på små och medelstora företag. Medan enskilda små och medelstora företag är naturligt mindre och har mindre inverkan på hållbarhetsarbetet än de större företagen, är deras engagemang viktigt för att uppnå nationella SS mål (Weingaertner & Moberg, 2011). Hållbarhet betraktas ofta som ett privilegium för stora företag eftersom de har tillräckliga medel för att förbättra sitt koldioxidavtryck (Rodgers, 2010). De små och medelstora företagens verksamhet är inte väl förstådd och dokumenterad, inklusive företagsetableringar inom samhällen, av vilka vissa är helt baserade på hållbara principer (Rodgers, 2010). Med tanke på att små och medelstora företag spelar en viktig roll för en hållbar utveckling är det viktigt att förstå de bakomliggande mekanismerna bakom varför små och medelstora företag är engagerade i SS inom samhällen. Syfte: Syftet med denna studie är att undersöka hur små och medelstora företag kan främja en samhällelig förmåga att utveckla socialt hållbara metoder som inte bara tillfredsställer de nuvarande medlemmarnas behov utan också stöder framtida generationers förmåga att bibehålla en hållbar samhällen. Metod: På grund av den begränsade litteraturen om social hållbarhet inom ramen för små och medelstora företag i samhället, använder denna avhandling en explorativ forsknings design tillsammans med kvalitativa och abduktiva metoder. Den kvalitativa innehållsanalysen används vid kodning och analys av empiriska fynd, och den abduktiva metoden används för att utveckla en utvidgad ram för social hållbarhet inom samhällen. Slutsats: Syftet med denna studie var att få insikt i de initiativ som små och medelstora företag genomför för socialt hållbara samhällen och de hinder de står inför. Genom kvalitativ forskning inom olika sektorer av ekonomin (jordbruk, byggande, service, detaljhandel, tillverkning) och olika länder, har en empirisk förståelse för hur små och medelstora företag engagerar sig i sociala hållbarhets initiativ härletts. De empiriska rönen resulterade i en utvidgning av en social hållbarhetsram som föreslogs av Eizenberg och Jabareen (2017). I den utvidgade ramen infördes samhälleligt kapital som det femte konceptet för SS och dess huvudkomponenter är humankapital, socialt kapital, social sammanhållning, social integration, naturkapital och filantropiska kapital. Mångfalden av sektorer och länder gjorde det möjligt för oss att ta hänsyn till kontextuella skillnader och utveckla en internationell syn på sociala hållbarhets begrepp som är relevanta för samhällen.

Background: India has the highest number of undernourished children worldwide. Understanding trends, predictors, and consequences of child undernutrition is important to inform strategy for addressing this public health crisis. Methods: We used data from four National Family Health Surveys (1992-93, 1998-99, 2005-6, 2015-16 NFHS) to examine trends of undernutrition before and after the 2005 implementation of the National Rural Health Mission, India’s flagship public health initiative (Aim 1). We used the 2016 NFHS to build a predictive model that identifies infants at-risk for child undernutrition (Aim 2). Lastly, we used data from the 2005 and 2012 India Human Development Surveys to investigate the consequences of early childhood undernutrition (Aim 3). Results: NRHM was more effective at addressing acute than chronic undernutrition but its prioritization on high focus states resulted in an increase of acute undernutrition among children living in normal focus states. We demonstrate that it is feasible to predict 5-year risk of child undernutrition at the time of birth. Child undernutrition is associated with adverse physical and cognitive outcomes during pre-adolescent years, with female undernourished children experiencing the worst outcomes. Higher female education in the household helps overcome gender and nutrition-based disadvantage among Indian children. Conclusion: There is an urgent need to reduce nutrition-related disparities among Indian children. Short-term strategy could include a predictive model that can be used to more effectively provide resources and intervention to the most disadvantaged population. Long term strategy should focus on elevating women’s status through improved female education in India.

O desenvolvimento municipal sustentável é um fenômeno complexo. Para que seja possível entender tal fenômeno, é necessário levar em consideração como se comportam as diversas variáveis de dimensões distintas e a interação de uma grande quantidade de atores envolvidos em um processo dinâmico, transformando constantemente o sistema social de uma determinada região. Esta dissertação tem em sua essência, ser um trabalho que está de acordo com o novo paradigma da ciência, descartando explicações simples e prontas sobre o desenvolvimento. Busca agregar toda a complexidade, instabilidade e intersubjetividade que o assunto compreende. Assim, o principal objetivo deste trabalho é desenvolver e diagnosticar o sistema de administração das prefeituras municipais para o desenvolvimento sustentável, tendo como base os objetivos de desenvolvimento sustentável (ODS), utilizando como métodos o Viable System Model (VSM) em prefeituras municipais e a criação de Indicador Sistêmico-Cibernético de Desenvolvimento Sustentável (ISCDS) por meio da análise fatorial (AF) para os municípios do estado de São Paulo. Os objetivos específicos também são desenvolvidos de maneira a contribuir ao objetivo principal. Dentre eles estão: diferenciar os diversos conceitos de desenvolvimento, identificar e delimitar o sistema onde acontece o desenvolvimento local, verificar como os ODS podem ser uma forma de promover o desenvolvimento sistêmico, identificar as principais variáveis secundárias que podem compor o desenvolvimento local e que estejam ligadas a cada um dos objetivos de desenvolvimento sustentável da ONU, desenvolver um indicador capaz de medir o desenvolvimento sistêmico utilizando os ODS e, por fim, identificar as diferenças entre os municípios do estado de São Paulo criando agrupamentos de municípios semelhantes. Para tanto, este é um trabalho sistêmico tanto em sua filosofia quanto estrutura, adotando métodos e técnicas tanto quantitativas como qualitativas para se chegar aos resultados das perguntas de pesquisa. Para que fosse possível obter conhecimento suficiente acerca dos temas tratados e propor uma base metodológica sólida de modo a mostrar os resultados esperados, optou-se por realizar um amplo referencial teórico, envolvendo três itens: desenvolvimento, abordagens sistêmico-cibernéticas e objetivos de desenvolvimento sustentável. Os resultados mostraram que é possível aplicar o VSM no sistema administrativo das prefeituras municipais, sendo uma poderosa ferramenta para administrar o a prefeitura de maneira eficiente e também útil para identificar diversas falhas sistêmicas, conforme são expostas nas considerações finais deste trabalho. Por meio da análise fatorial, tendo como base os ODS, foi possível desenvolver um modelo para se medir o desenvolvimento sustentável sistêmico municipal: o ISCDS para os 645 municípios do estado de São Paulo. A partir da obtenção do ISCDS, foram encontrados sete clusters com características diferentes, indicando a necessidade de tratativas administrativas diferentes que visem o desenvolvimento sustentável para cada agrupamento encontrado. / Sustainable municipal development is a complex phenomenon. To understand this phenomenon, it is necessary to take into account not only the way of huge number variables of different dimensions behave, but also how the large number of actors are involved in a dynamic process, constantly transforming the social system of a given region. This dissertation has in its essence, to be a work that is in accordance with the new paradigm of science, discarding simple and ready explanations about development. It seeks to add all the complexity, instability and intersubjectivity that the subject comprehends. Thus, the main objective of this work is to develop and diagnose the municipal town hall administration system for the sustainable development, based on the sustainable development goals (SDG). The methods used are the Viable System Model (VSM) for the municipal town hall management, and the factor analysis to model the Systemic-Cybernetic Indicator of Sustainable Development (SCISD) for the municipalities of the state of São Paulo. Specific objectives are also developed in order to contribute to the main objective. These include: a) to differentiate the various development concepts, b) to identify the system where local development takes place, b) to check how the SDGs can promote systemic development, c) to identify the main variables that could be used to measure sustainable development, and which of them are connected to each of the UN\'s SDGs and, finally, d) to identify the differences between the municipalities of the state of São Paulo, creating clusters of similar municipalities according to the SCISD developed. To do so, this is a systemic work both in its philosophy and structure. It was adopted methods and techniques both quantitative and qualitative to explore to the results of the research questions. In order to obtain sufficient knowledge about the topics addressed and to propose a solid methodological basis to show the expected results, it was decided to make a broad theoretical reference, involving three items: development, systems thinking and cybernetics approaches and sustainable development goals. The results showed that it is possible to apply the VSM in the administrative system of the city halls, being a powerful tool not only to manage the city in an efficient way, but also useful to identify several systemic failures, as they are exposed in the final considerations of this work. Through the factorial analysis, based on the SDGs, it was also possible to develop a model to measure the level of municipal sustainable development: the SCISD for the 645 municipalities of the state of São Paulo. Also, from the SCISD, seven clusters with different characteristics were found, indicating the need for different administrative approaches according to the different at sustainable development characteristics found in each cluster.

The purpose of this thesis is to analyze the understanding of human rights in Agenda 2030 and the role of companies by adopting a human rights-based approach to sustainable development. It applies a qualitative idea analysis of the primarily material where central concepts are operationalized by constructing a model of analysis based on dimensions. The dimensions of human rights as moral, politics and law, derives from previous research by the ethical theorist Elena Namli. A potential fourth dimension, the economic dimension of human rights, is further developed, applying research of the economists Dan Seymour and Jonathan Pincus. Furthermore, this research considers what Agenda 2030 indicates in terms of human rights obligations for companies and the impacts the perceived role of companies may have for human rights. Therefore, the theoretical framework is complemented by research of the political theorist Thomas Pogge's, and international lawyer Andrew Clapham’s ideas of human rights obligations for companies. The results show that Agenda 2030 encourages a multi-stakeholder approach and addresses companies as partners in order to achieve a sustainable development based on human rights. This can be regarded as an opportunity to enhance the respect, protection and fulfillment of human rights, inviting more actors to contribute in a complementary way to states. At the same time challenges remains in creating policies, accountability and monitoring mechanisms towards companies bothin terms of human rights and companies’ performance on the SDGs. Until there is more legal clarity, the moral question of what is good and fair business practice becomes central.

Inledning- Det har satts upp mål på både global och nationell nivå för att bekämpa klimatförändringarna som sker på vår planet. Mat och måltider berörs direkt och indirekt av flera av dessa mål. På avdelningen Måltidsservice i Härryda kommun har arbete med att miljöutveckla skolmaten skett i mer än ett decennium, något som de ansvariga önskade en uppföljning på.  Syfte- Att undersöka om och i så fall hur klimatavtrycket från skolmaten i Härryda kommuns gymnasieskola har förändrats från år 1993 till 2020. Ett andra syfte är att undersöka eventuella förändringar i skollunchernas innehåll med avseende på livsmedel under samma tidsperiod. Material och metod- För att undersöka eventuella förändringar i klimatavtryck över tid har skolluncher från stickprov i tidsperioden 1993-2020 klimatberäknats. För att se eventuella förändringar i skollunchernas innehåll har frekvenser på fem utvalda livsmedel studerats.  Resultat- Det finns ingen signifikant skillnad i CO₂emellan period 1 (1993+1998+2003) och period 2 (2013+2018+2020). Där finns svaga tendenser som tyder på minskning i skolmatens klimatavtryck under det senaste decenniet. Förekomsten av rent nötkött, produkter av gris och ris har minskat i skolluncherna medan vegetabiliskt protein och kött från fågel har ökat.  Slutsats-Någon signifikant skillnad i klimatavtryck mellan 1993 och 2020 kunde inte fastställas. Det fanns tydliga förändringar i skollunchernas innehåll med avseende på livsmedel under samma tidsperiod. / Introduction-Targets have been set at both global and national levels to fight the climate changes that are happening on our planet. Food and meals directly and indirectly affect several of these goals. For more than a decade the Meal service-department in Härryda kommun have been working on making their school meals more sustainable and now they want a follow-up on that.  Aims- To investigate if and in that case how the carbon footprint from the high school of Härryda kommun’s school meals has changed from 1993 to 2020. A second purpose is to investigate any changes in the content of the school lunches referred to foods. Materials and methods-In order to investigate possible changes in carbon footprints over time, samples of school lunches in the time period 1993-2020 have been calculated. In order to see any changes in the content of the school lunches, frequencies of five selected foods have been studied. Results-There is no significant difference in CO₂e between period 1 (1993 + 1998 + 2003) and period 2 (2013 + 2018 + 2020). There are small tendencies that indicate a decrease in carbon footprint from the school meals in the last decade. The presence of pure beef, products of pig and rice have decreased in the school meals, while plant-based protein and meat from birds have increased. Conclusion-No significant difference in climate imprint between 1993 and 2020 could be determined. There were obvious changes in the content of the school lunches with regard to food during the same time period.

OBJETIVOS: Determinar la desigualdad de la prevalencia de desnutrición crónica infantil en función a algunos determinantes sociales en países de América Latina y el Caribe (ALC)  MÉTODOS: Se realizó un estudio ecológico con los indicadores de desarrollo de la base de datos del Banco Mundial. Se analizaron los indicadores de 19 países (acceso a electricidad y servicios básicos de agua en población rural, PBI per cápita, gasto en salud per cápita). La desigualdad absoluta y relativa se determinó mediante el Índice de Kuznets absoluto, y relativo, la gradiente de la desigualdad a través de índice de las gradientes de la desigualdad, y para la desigualdad proporcional se usó el (índice de concentración de salud) ICS y la curva de concentración. RESULTADOS: la brecha de las desigualdades en la prevalencia de desnutrición crónica infantil entre los países de ALC se mantuvo prácticamente sin cambios significativos a lo largo del periodo estudiado. El 20% de los países con mayor desventaja concentran el 40% de la prevalencia de desnutrición crónica mientras que el 20% de los países con mayor ventaja solo el 7-8%, medido a través del ICS. CONCLUSIONES: A pesar de que en los Objetivos de Desarrollo del Milenio se encontraban eliminar la desnutrición, ésta permanece. La brecha de desigualdad ha disminuido respecto a la gradiente de desigualdad (desigualdad absoluta), sin embargo, la desigualdad proporcional se ha mantenido igual. Para eliminar esta brecha en ALC se deben generar políticas para distribuir de forma más eficiente y equitativa los recursos destinados al gasto en salud y los sectores relacionados, para de esa forma enfocarse en los determinantes sociales debidos. / OBJECTIVES: determinate the inequality of the prevalence of chronic childhood malnutrition according to some social stratifiers in the countries of Latin America and the Caribbean (LAC) METHODS: An ecological study was carried out at the country level with the development indicators of the World Bank database. The indicators of 19 countries will be analyzed (access to electricity and basic water services in rural areas, GDP per capita, health expenditure per capita). The absolute and relative inequality was determined by the absolute and relative Kuznets index, gradient of the inequality through the graduation index of the inequality, in addition, the proportional inequality was calculated through the index of concentration in health and the curve of concentration. RESULTS: the gap of inequalities in the prevalence of chronic child malnutrition in the LAC countries, remained practically without significant changes throughout the period studied. In addition, 20% of the countries with the greatest disadvantage accounted for 40% of the prevalence of chronic malnutrition compared to 20% of the countries with the greatest advantage, which presented 7-8% of the prevalence through the index of concentration on health. CONCLUSIONS: Although the Millennium Development Goals were to eliminate malnutrition, it was not possible to do so. However, the inequality gap has partially decreased. To eliminate it In LAC, wealth should be distributed more efficiently, and equitable resources allocated to health spending and related sectors. As well as generating Policies to address inequalities in and between countries. / Tesis

Orientador: José Antônio Perrella Balestieri / Resumo: A abordagem do nexo água-alimento-energia (AAE) leva em consideração a interdependência do uso desses recursos, essenciais para o bem-estar humano, e possibilita analisar os indicadores dos Objetivos de Desenvolvimento Sustentável (ODS). Nesta inter-relação é necessária uma abordagem sistêmica para compreender como a interação de cada componente funciona e se estrutura. Na presente tese foi analisado o nexo AAE e a rede de influências entre as cidades, no atendimento aos Objetivos do Desenvolvimento Sustentável, tendo o município de Cunha, no Estado de São Paulo, em posição central entre os demais municípios estudados. A vertente analisada encontra-se na transição entre o extenso Vale do Paraíba, situado entre duas metrópoles (São Paulo e Rio de Janeiro) e a baixada litorânea (Paraty e Ubatuba), tendo o município de Cunha em posição intermediária. A região estudada é drenada pelos rios Paraibuna, Paraitinga e seus afluentes que constituem fonte significativa de abastecimento de grandes cidades do sudeste brasileiro e oferece suas águas para irrigação, abastecimento, indústria e produção de energia hidroelétrica. Para análise do nexo AAE, os parâmetros da produção de alimento e o consumo de água e energia foram avaliados estatisticamente, com uso do coeficiente de correlação de Pearson (cP). A análise considerou a produção agrícola e a relação com o consumo de água e energia, assim como a produção pesqueira frente aos referidos parâmetros, em escala de municípios. Dentre as an...

In this interrelation, a systemic approach is required to understand how the interaction of each component works and is structured. In this thesis, the AAE nexus and the network of influences between cities were analyzed, in compliance with the Sustainable Development Goals, with the municipality of Cunha, in the State of São Paulo, in a central position among the other municipalities studied. The analyzed slope is found in the transition between the extensive Vale do Paraíba, located between two metropolises (São Paulo and Rio de Janeiro) and the coastal lowland (Paraty and Ubatuba), with the municipality of Cunha in an intermediate position. The studied region is drained by the Paraibuna, Paraitinga Rivers and their tributaries, which constitute a significant source of supply for large cities in southeastern Brazil and offers their waters for irrigation, supply, industry, and hydroelectric power. For analysis of the WFE nexus, the parameters of food production and the consumption of water and energy were evaluated, statistically with use of Pearson's correlation coefficient (cP). The analysis considered agricultural production and the relationship with water and energy consumption, as well as fishery production against these parameters, ...
