[pt] A Agenda Ambiental Global tem como uma das principais diretrizes a redução da pegada ecológica para a produção de alimentos. Parte desse desafio está associada a vastas áreas de pastagem degradadas. No Brasil, 70 porcento da área total de pastagem utilizada pela pecuária é diagnosticada como degradada, representando 118,3 milhões de hectares. Nesse contexto, algumas estratégias podem ser usadas para reverter esse cenário, sendo uma delas a transição para um sistema de produção agroecológico sustentável, como o Sistema Silvipastoril (SSP). Como Estudo de Caso para esta pesquisa, foi escolhida uma paisagem tropical e montanhosa na região Sudeste do Brasil, com baixo potencial de mecanização, fato que diminui sua competitividade no agronegócio, contribuindo para um longo período de declínio social, ambiental e econômico, principalmente a partir da década de 1950. O objetivo da pesquisa consistiu em avaliar o SSP como uma ferramenta estratégica para a recuperação de terras degradadas da Bacia Hidrográfica do Rio Paraibuna (BHRP), considerando as três dimensões da sustentabilidade: social, ambiental e econômica. Para isso, foram levantados dados de 6 fazendas de gado alimentado, exclusivamente, a pasto: 2 (duas) de pecuária degradada em monocultura (PDM); 2 (duas) de pecuária produtiva em monocultura (PPM); e 2 (duas) de pecuária produtiva em Sistema Silvipastoril (PPSP). Um conjunto de indicadores foi desenvolvido e utilizado para avaliar princípios e metas que orientam a transição de sistemas de produção convencionais para sistemas sustentáveis. Os resultados apresentaram uma escala progressiva de evolução na sustentabilidade entre todos os sistemas de produção pesquisados como: PPSP (0,75) maior PPM (0,61) menor PDM (0,42), nos aspectos social, ambiental e econômico, sendo 0,7 o ponto de equilíbrio para a sustentabilidade e 1,0 o máximo. Dessa forma, esta pesquisa apresenta o alto potencial do SSP como ferramenta estratégica para recuperar as 3 dimensões da sustentabilidade em terras degradadas. Os principais benefícios são: a adoção de boas práticas de produção; a capacidade produtiva do solo; a diversificação da paisagem; a vegetação nativa; a saúde e segurança no trabalho; a rentabilidade e segurança do investimento; e a lucratividade. / [en] One of the main guidelines of the global environmental agenda is lowering the ecological footprint for food production. Part of this challenge is associated with vast areas of degraded pasture. In Brazil, 70 percent of the total pasture area used by livestock is diagnosed as degraded, representing 118.3 million hectares. Some strategies can be used to reverse this scenario. One of these is a transition process for a sustainable agro-ecological productions system, such as Silvopastoral Systems (SPS). As a case study it was chosen a tropical landscape in a mountainous region in the southeast of Brazil. It has low potential for mechanization, which decreases its competitiveness in agribusiness, contributing for a long period of social, environmental and economic decline, especially after the 1950 s. This paper aims to evaluate SPS as a strategic tool for the recovery of degraded lands in the Paraibuna River Basin (BHRP), considering the three dimensions of sustainability: social, environmental and economic. We surveyed data from six grass-fed cattle farms: two of degraded monoculture pasture (DMP); two of productive monoculture pasture (PMP); and two of productive Silvopastoral System (PSPS). A set of indicators was developed and used to evaluate principles and goals that guide the transition from conventional production systems to sustainable systems. The results presented a gradual scale of sustainability evolution among all production system surveyed such as PPSP (0.75) PMP (0.61) DMP (0.42), in social, environmental and economic aspects, with 0.7 being the breakeven score for sustainability and 1.0 the maximum. In this way, this research presents the high potential of SPS as a strategic tool to recover the three dimensions of sustainability in degraded lands, being the main benefits, a better: production practices adoption; soil productive capacity; landscape diversification; native vegetation; health and safety at work; profitability and security of investment; and diversification income.

Tesis por compendio / [ES] The pursuit of sustainable development in urban areas is crucial due to their significance as the primary human habitat and resource consumer. Rapid urbanization poses significant challenges for city management, necessitating actions to ensure sustainability and mitigate resource depletion. The conservation of water resources turns out to be an important focus, particularly in society's development due to the number of factors that depend on this resource. Water resources are essential for, serving critical roles in human health, agriculture, and industry, while also facilitating economic activities, cultural values, and climate regulation. In this context, the sustainability of water systems encompasses social, environmental, economic, and asset dimensions. Nevertheless, the accelerated social growth, exacerbates the strain on water supplies, necessitating measures to ensure sustainability. Key considerations include ensuring equitable access to water services, minimizing environmental impact, implementing cost-effective policies, and enhancing infrastructure resilience. Adopting sustainable practices encounters obstacles, particularly in data measurement and analysis, hindered by the complexities of emerging technologies. Addressing these challenges requires leveraging indicators to assess progress towards Sustainable Development Goals (SDGs) quantitatively. Despite significant strides, evaluating progress toward SDGs remains a complex task, particularly in urban water systems. Consequently, ongoing efforts are essential to advance sustainable development initiatives and ensure the long-term viability of urban water resources. Even though the SDGs have motivated several projects to advance sustainable development. However, it is complex to determine the progress made in fulfilling these goals, especially in particular cases like urban water systems. The development of a framework to measure sustainability in urban water systems contributes to the decision- making process to optimize system performance across the entire water cycle. These decision-making processes are crucial for various stakeholders, including governmental entities, the general population, and, of course, water resource managers. Considering the above, the main objective of this doctoral thesis consists of the development of a methodology to measure and categorize hydraulic systems according to their contribution to sustainability from their three dimensions. The methodology is based on the implementation of a series of indicators linked to each of the goals of the Sustainable Development Goals established by the UN. In this way and as a result of this work, it will be possible to categorize any type of urban water system with labels that indicate the level of contribution to achieving the SDGs and highlight the importance of water resources in meeting the SDGs. Also, another objective of the methodology's implementation is to validate by assessing the progress of the indicators if it is sufficient, or if acceleration and additional measures are required. This will serve as a benchmarking tool, as a support point for decision-making by the different actors involved in hydraulic management, thus achieving more sustainable water management. To achieve this objective, the doctoral thesis has been developed in three phases, the results of which have been published in 3 articles in indexed journals (JCR). The phases of work development are as follows: (i) Contextualization and development of the methodology (Publication I): an investigation was carried out on the concept of sustainability and what it encompassed, as well as the definition of the goals, their progress, and indicators currently used by both the UN and other entities for the evaluation of these. To complement this, case studies of urban hydraulic systems in which sustainability was evaluated were reviewed. Based on the information collected and as a result of the research, the evaluation methodolo / [CA] La cerca del desenvolupament sostenible en les zones urbanes és crucial a causa de la seua importància com a principal hàbitat humà i consumidor de recursos. La ràpida urbanització planteja desafiaments importants per a la gestió de la ciutat, la qual cosa requerix accions per a garantir la sostenibilitat i mitigar l'esgotament dels recursos. La conservació del recurs hídric resulta ser un focus important, particularment en el desenvolupament de la societat a causa de la quantitat de factors que depenen d'este recurs. Els recursos hídrics són essencials per a exercir funcions crítiques en la salut humana, l'agricultura i la indústria, al mateix temps que faciliten les activitats econòmiques, els valors culturals i la regulació del clima. En este context, la sostenibilitat dels sistemes hídrics abasta dimensions socials, ambientals, econòmiques i d'actius. No obstant això, el creixement social accelerat exacerba la pressió sobre el subministrament d'aigua, la qual cosa requerix mesures per a garantir la sostenibilitat. Les consideracions clau en este assumpte inclouen garantir l'accés equitatiu als servicis d'aigua, minimitzar l'impacte ambiental, implementar polítiques rendibles i millorar la resiliència de la infraestructura. L'adopció de pràctiques sostenibles troba obstacles, particularment en el mesurament i anàlisi de dades, obstaculitzats per les complexitats de les tecnologies emergents. Per a abordar estos desafiaments és necessari aprofitar els indicadors per a avaluar quantitativament el progrés cap als Objectius de Desenvolupament Sostenible (*ODS). Malgrat els importants avanços, avaluar el progrés cap als *ODS continua sent una tasca complexa, particularment en els sistemes d'aigua urbans. En conseqüència, els esforços continus són essencials per a promoure iniciatives de desenvolupament sostenible i garantir la viabilitat a llarg termini dels recursos hídrics urbans. Encara que els *ODS han motivat diversos projectes per a avançar en el desenvolupament sostenible. No obstant això, és complex determinar els avanços en el compliment d'estes metes, especialment en casos particulars com els sistemes d'aigua urbans. El desenvolupament d'un marc per a mesurar la sostenibilitat en els sistemes d'aigua urbans contribuïx al procés de presa de decisions per a optimitzar el rendiment del sistema al llarg de tot el cicle de l'aigua. Estos processos de presa de decisions són crucials per a diverses parts interessades, incloses entitats governamentals, la població en general i, per descomptat, els administradors de recursos hídrics. Considerant l'anterior, l'objectiu principal d'esta tesi doctoral consistix en el desenvolupament d'una metodologia per a mesurar i categoritzar els sistemes hidràulics segons la seua contribució a la sostenibilitat des de les seues tres dimensions. La metodologia es basa en la implementació d'una sèrie d'indicadors vinculats a cadascuna de les metes dels Objectius de Desenvolupament Sostenible establits per l'ONU. D'esta manera i com a resultat d'este treball, serà possible categoritzar qualsevol tipus de sistema d'aigua urbà amb etiquetes que indiquen el nivell de contribució a l'assoliment dels *ODS i ressalten la importància dels recursos hídrics en el compliment dels *ODS. Així mateix, un altre objectiu de la implementació de la metodologia és validar avaluant l'avanç dels indicadors si és suficient, o si es requerix acceleració i mesures addicionals. Això servirà com a ferramenta de benchmarking, com a punt de suport per a la presa de decisions dels diferents actors implicats en la gestió hidràulica, aconseguint així una gestió més sostenible de l'aigua. Per a aconseguir este objectiu, la tesi doctoral s'ha desenvolupat en tres fases, els resultats de les quals s'han publicat en 3 articles en revistes indexades (*JCR). Les fases del desenvolupament del treball són les següents: (i) Contextualització i desenvolupament de la metodologia (Publicació I): es va realitzar una investigació sobre e / [EN] The pursuit of sustainable development in urban areas is crucial due to their significance as the primary human habitat and resource consumer.
