In the era of the Anthropocene, cities are facing significant social, economic and environmental changes that, unlike previous historical periods, are occurring extremely rapidly. The acronym b.e.t. - included in the title - refers to the word bet, whose definition is closely linked to the concepts of unpredictability and risk. But the word bet also refers to the notion of opportunity understood positively as the possibility of success. The challenge that the cities of the 21st century have to face concerns the overcoming of the limits and rigidities of the current urban planning, which seems inadequate to manage the new dynamics in action. The term resilience has been introduced in the lexicon of urban planning and architecture to support a new approach to the management of the contemporary city, capable of implementing the attributes of diversity, variability and redundancy of the urban system. The structure of this research wants to retrace the holistic nature of the theme and is proposed as a mosaic of projects, tools and strategies that have the potential to assemble each time in a different way. The objective is to emphasize the importance of triggering in the urban system a plurality of actions, capable of acting simultaneously on multiple levels to ensure processes suitable for change and multifunctional. This research does not intend to trace a defined path, the assumptions of flexibility and adaptability related to the definition of resilience do not allow to define a new urban planning technique based on a model to be followed for the management of the territory, but proposes an open framework of possibilities to guide the cities towards the ecological transition and make them increasingly livable, comfortable, happy, vibrant and beautiful.

A transição agroecológica, enquanto um processo de estímulo à adoção de práticas agrícolas sustentáveis implica na gradual construção do conhecimento agroecológico, por meio da troca de saberes, experiências e interpretação dos (as) agricultores (as) sobre os contextos em que vivem e produzem, configurando-se em um modo alternativo de produção, em contraponto ao modelo atual convencional. Novos caminhos que tragam a conservação da biodiversidade, a autorrealização individual e comunitária, e a autogestão política e econômica são prioritários e urgentes. A presente pesquisa teve por objetivo sistematizar a experiência de transição agroecológica da CooperAPAs, localizada em Parelheiros, zona sul do município de São Paulo, por meio da identificação de representações de agroecologia, relações saúde, ambiente e políticas públicas, bem como os principais interesses e dificuldades de agricultores e técnicos envolvidos em algum momento específico da trajetória de formação, implementação e/ou desenvolvimento da CooperAPAs. Foi utilizado o método de sistematização de experiências, tendo como instrumentos de pesquisa a análise documental, entrevistas e oficina de construção da linha do tempo. De modo geral, os participantes reconheciam impactos positivos e negativos de suas ações sobre a saúde e o ambiente. Dentre as necessidades identificadas, destacou-se maior sensibilização e empoderamento de todos os cooperados, para que possam contribuir mais ativamente no fortalecimento da cooperativa, a fim de garantir maior acesso às políticas públicas vigentes, ao mercado, e à comercialização, melhorando, consequentemente, condições socioambientais e econômicas destes agricultores. Para tal, recomenda-se a adoção, pela cooperativa, de estratégias socioeducativas participativas, como a Aprendizagem Social, que favoreçam o diálogo, a negociação de conflitos e a gestão compartilhada, como um novo caminho para a CooperAPAs. / The agroecological transition, as an incentive to process the adoption of sustainable agricultural practices, implies the gradual construction of agroecological knowledge through the exchange of knowledge, experiences and interpretation of the farmers about the contexts in which they live and produce by setting up an alternate mode of production, in contrast to conventional current model. New ways to bring biodiversity conservation, self individual achievement and community, and the political and economic self-management, are priorities and urgent. This study aimed to systematise the agroecological transition experience of CooperAPAs, located in Parelheiros, south zone of São Paulo, through the identification of agroecology representations, healthy relationships, environment and public policy, and the main interests and difficulties of farmers and technicians involved in any specific time of training course, implementation and / or development of CooperAPAs. We used the method of systematization of experiences, having as research tools to document analysis, interviews and the timeline building workshop. In general, participants recognized both positive and negative impacts of their actions on health and the environment. Among the identified needs, there is increased awareness and empowerment of all members, so that they can contribute more actively in strengthening the cooperative in order to ensure greater access to existing public policies, market, and marketing, improving, consequently, social, environmental and economic conditions of these farmers. To this end, it recommends the adoption by the cooperative, participatory social and educational strategies such as social learning, to encourage dialogue, conflict negotiation and shared management, as a new way to CooperAPAs.

L’entreprise est une liberté ambigüe, elle est autant un facteur de progrès que de risque. La crise écologique actuelle conduit les entreprises à prendre conscience des effets de leurs activités sur la société dans son ensemble et l’environnement. Pressées par de nouvelles normes sociales de la société civile, les entreprises sont amenées à modifier leur comportement, notamment à travers une démarche de responsabilité sociétale et environnementale. C’est alors la société commerciale - enveloppe juridique de l’entreprise, non définie par le droit quant à elle - qui est interrogée dans sa définition et sa fonction sociale. En témoigne la récente réforme du contrat de société commerciale pour y intégrer la prise en compte d’enjeux sociaux et environnementaux. C’est surtout l’adoption d’engagements volontaires qui participe d’une modification de la société commerciale à travers l’élaboration par des personnes de droit privé, de normes de droit souple, c’est-à-dire dénuées de la contrainte. Phénomène qualifié de droit post-moderne, les engagements volontaires amènent l’entreprise à hisser son comportement standard à un degré de responsabilité supérieur au droit "de lege lata", permettant éventuellement d’aboutir à l’engagement de sa responsabilité juridique par l’introduction d’une action en justice. Aussi, le développement des formes sociétaires de l’économie sociale et solidaire et l’apparition de sociétés inspirées de modèles étrangers sont une première brèche dans l’approche classique de la société commerciale. Constatant l’insuffisance de la RSE et des formes sociétaires de sociétés commerciales responsables à prendre véritablement en considération les enjeux environnementaux, il est proposé de conceptualiser une « entreprise sobre ». Un travail de réflexion sur la sobriété, concept juridique émergent, est effectué à partir de la terminologie déjà présente dans la législation. La définition juridique de la sobriété et plus précisément, ce qui constitue un comportement sobre doit permettre de fournir une aide à l’intégration de l’environnement dans l’entreprise. Ou pour le juge, de caractériser le standard juridique du comportement sobre. Des instruments de caractérisation d’un comportement sobre sont envisagés à travers une relecture des éléments du contrat de société commerciale (associé, apport, bénéfice, objet social et intérêt social). Ces développements soulevés à l’appui d’une dynamique de changement de la société commerciale, doivent permettre de mettre en exergue la nécessité de définir l’entreprise à partir de sa fonction sociale et comme un système en vue de satisfaire des intérêts communs. / Business is an ambiguous idea of freedom, it is as much a vehicule of progress as a risk. The current ecological crisis is leading enterprises to take into account the effects of economic activity on society and environment. Pressured by new social standards, enterprises are led to change their conduct, especially through a societal and environmental responsibility approach. Then, it is the commercial company – the legal entity of the enterprise, not defined by french law – that is questioned in its definition and its social function. This is reflected in the recent reform of the french commercial company contract to consider social and environmental issues. It’s mainly the adoption of voluntary commitments that contributes to a change in the commercial company through the elaboration by private law persons of soft-law, i.e. norms devoid of coercion. As a post-modern law phenomenom, voluntary commitments lead the company to raise its standard behaviour to a higher degree of responsibility than de lege lata law, may succeed to the engagement of its legal liability. Also, the development of the social and solidarity economy’s corporate forms and the emergence of enterprises inspired by foreign models are a first breach in the classical commercial company approach. Noting the inadequacy of CSR and the corporate forms of responsible commercial companies to really take into account environmental issues, it is proposed to conceptualize a « sober enterprise ». A reflection on sobriety, an emerging legal concept, is carried out on the basis of the terminology already present in the legislation. The juridical definition of sobriety and more precisely, what constitutes sober behaviour, must make it possible to provide support for the integration of the environment into the enterprise. Or for the judge, to characterize the legal standard of sober behaviour. Instruments for characterizing sober behaviour are considered through a review of the elements of the commercial company contract (associate, contribution, profit, social purpose and social interest). These developments are raised in a dynamic of change of the the commercial company and should highlight the need to define the enterprise : both on its social function and to reach to satisfy common interests.

This milestone presents a pool of available indicators and indicator systems which go beyond the narrow concepts of national economic accounts as well as a structuring of the indicators and indices according to central areas of well-being. The milestone builds the basis for Task 202.2, where a subset of indicators will be selected based on different theoretical frameworks, e.g. services / functionings, needs. Some of the indicators will be included in the macro-economic models in order to account for key dimensions of sustainability. / Series: WWWforEurope

Questioning GDP as dominant indicator for economic performance has become commonplace. For economists economic policy always aims for a broader array of goals (like income, employment, price stability, trade balance) alongside income, with income being the priority objective. The Stiglitz-Sen-Fitoussi Commission argued for extending and adapting key variables of macroeconomic analysis. International organisations such as the EC, OECD, Eurostat and UN have proposed extended arrays of macroeconomic indicators (see 'Beyond GDP', 'Compendium of wellbeing indicators', 'GDP and Beyond', 'Green Economy', 'Green Growth', 'Measuring Progress of Societies'). Despite these high profile efforts, few wellbeing and environmental variables are in use in macroeconomic models. The reasons for the low uptake of socio-ecological indicators in macroeconomic models range from path dependencies in modelling, technical limitations, indicator lists being long and unworkable, choices of indicators appearing ad hoc and poor data availability. In this paper we review key approaches and identify a limited list of candidate variables and - as much as possible - offer data sources. / Series: WWWforEurope

Na ótica ambiental, a adoção dessas práticas sustentáveis possibilitaria a manutenção dos recursos naturais e da produtividade agrícola por um grande período, gerando menos impactos adversos ao ambiente e aperfeiçoando a produção com um mínimo de insumos externos possíveis. No entanto, o desenvolvimento rural sustentável não se alcança apenas com a adoção de práticas alternativas de cultivo no campo. Trata-se mais, por uma parte, de um ideal, como a justiça social, e por outra parte, de um projeto de sociedade que deve ser construído tecnicamente, socialmente e politicamente. Muitos agricultores familiares do brejo paraibano têm adotado práticas alternativas de manejo agrícola, em especial no município de Lagoa Seca. Apesar de recentes na adoção de um modelo alternativo de agricultura, estes pequenos produtores declaram seguir os princípios agroecológicos, conquistando novos adeptos ao processo de transição agrícola nesta região. Essa pesquisa teve como objetivo principal identificar as práticas adotadas pelos agricultores familiares do município de Lagoa Seca, destacando as experiências locais vivenciadas e sua viabilidade socioeconômica e ambiental para a região, considerando os princípios da Agroecologia como mecanismo orientador e determinante para tal análise. Para obtenção dos dados requeridos pela pesquisa, foram avaliadas 20 propriedades agroecológicas localizadas no município de Lagoa Seca, na Paraíba, distribuídas nas seguintes regiões: Oiti, Cumbe, Floriano e Alvinho. Esta pesquisa é de natureza qualitativa e teve o estudo de caso como estratégia de pesquisa realizada através de questionário base, observação in loco (caminhada no entorno do estabelecimento) e da aplicação de entrevista semi-estruturada. As práticas adotadas pelos agricultores agroecológicos de Lagoa Seca proporcionam a conservação do solo, da água e da biota local garantindo a manutenção em longo prazo desses recursos naturais às atuais e futuras gerações. As mudanças no quadro político institucional da região trouxeram inúmeros benefícios sociais e econômicos para as comunidades agroecológicas, além de ter fortalecido o processo de transição agroecológica através da cooperação e dedicação entre os atores envolvidos. Também verificou-se alguns pontos negativos como a deficiência no sistema de esgotamento sanitário e tratamento da água de consumo humano e animal que podem vir a comprometer a imagem do produto agroecológico nos diversos canais de comercialização, como também a saúde do agricultor e de sua família. As práticas agroecológicas de natureza socioeconômica e ambiental proporcionaram consideravelmente a melhoria da qualidade de vida dos agricultores familiares do município de Lagoa Seca na Paraíba, demonstrando a importância da Agroecologia como ferramenta indispensável para o alcance do desenvolvimento rural sustentável. / Facing the necessity for changes in the environmental and social crisis scenario that we live today, arises the agro ecology as a field of knowledge able to indicate sustainable alternatives replacing the predatory practices of the capitalist agriculture. At the environmental view, the adoption of these sustainable practices would enable the maintenance of natural resources and the agricultural productivity during a big period, generating less adverse impacts to the environment and improving the production with minimal possible external inputs. However, the sustainable rural development is not reached only with the adoption of alternative practices of cultivation in the field. It is more an ideal, as the social justice, and in the other hand, a project from the society which must be built technically, socially and politically. Many family farmers from Brejo area in the Paraíba state have adopted alternative practices of agriculture management, especially in Lagoa Seca city. Despite recent in the adoption of an alternative model of agriculture, these small producers declare to follow the agro ecological principles, gaining new fans to the process of agriculture transition in this region. This study aims to identify the adopted practices by family farmers in Lagoa Seca city, highlighting the local experiences, experienced, and their social economic and environmental viability to the region, considering the agro ecology principles as a guide mechanism and determinant for such analysis. To achieve the required data by this research, it has been evaluated 20 agro ecological properties located at Lagoa Seca city, Paraíba state, distributed in the following regions: Oiti, Cumbe, Floriano and Alvinho. This research is qualitative and had the case study performed through a base questionnaire, observation in loco (walk around the establishment) and application of semi-structured interview. The adopted practices by agro ecological farmers from Lagoa Seca have provided the conservation of soil, water and the local biota ensuring long-term maintenance of these natural resources to current and future generations. The changes in the institutional political scenario have brought uncountable social and economic benefits to the agro ecological communities; besides strengthen the process of agro ecological transition through the cooperation and dedication among the involved characters. It has been verified also some negative points like the deficiency in the sewage system and water treatment for animal and human consumption which may pledge the agro ecological product image in the various marketing channels, as well as the farmers’ health and their family. The agro ecological practices of social economic and environmental features have provided considerably the improvement of the life quality of the family farmers from Lagoa Seca city, Paraíba state, showing the importance of agro ecology as an indispensable tool to reach the sustainable rural development.

Linking this issue to the future prospects of these adolescents, it was proposed to listen to the speech of this youth who experienced this process as well as to the professionals who worked with them. We chose to carry out a qualitative research in a host institution of the city of Manaus. With reference to the theory of Urie Bronfenbrenner method of anchoring the Ecological Integration, semi-structured interviews were conducted with five subjects, including adolescents and members of staff of that institution, as well as participant observation. Through the method of organizing data for Meaning Core, we obtained the following results: the process of leaving the shelter contradictory meanings being viewed both positively and negatively. However there is a predominance of negative meanings, suggesting the lack of effectiveness of the actions that should be favored by the institution in the promotion of life projects for young people. The reports revealed that the institution does not promote the ecological transition by providing resources for adolescents coping with adverse situations, although some positive experiences can be reported. We conclude that institutional practices need to be reformulated achieving greater interconnection between the ecological systems that must integrate the development of these young people / Partindo de diálogos estabelecidos entre a perspectiva Bioecológica do desenvolvimento e a psicologia Sócio-Histórica, o presente estudo objetivou compreender os múltiplos sentidos atribuídos ao processo de transição ecológica que corresponde ao desligamento de adolescentes que vivenciaram situação de abrigamento. Articulando esta questão às perspectivas de futuro destes adolescentes, propôs-se dar visibilidade às falas de jovens no momento em que vivenciavam esse processo, bem como dos profissionais que com eles atuam. Optou-se pela realização de uma pesquisa qualitativa em uma instituição de acolhimento da cidade de Manaus. Tendo como referência a teoria de Urie Bronfenbrenner ancorando o método de Inserção Ecológica, foram realizadas entrevistas semi estruturadas com cinco sujeitos, dentre eles adolescentes e membros do corpo técnico da referida instituição, além da observação participante. Através do método de organização de dados por Núcleos de Significação, foram obtidos os seguintes resultados: o processo de saída abriga sentidos contraditórios sendo visto tanto positiva como negativamente. Contudo há predomínio dos sentidos negativos, sugerindo a ausência de efetividade das ações que deveriam ser favorecidas pela instituição na promoção de projetos de vida aos jovens. As falas revelam que a instituição não favorece a transição ecológica provendo os adolescentes de recursos para o enfrentamento de situações adversas, ainda que algumas experiências positivas possam ser relatados. Conclui-se que as práticas institucionais necessitam ser reformuladas favorecendo uma maior interligação entre os sistemas ecológicos que devem integrar o desenvolvimento destes jovens

L’écologie territoriale est un champ de recherche qui propose d’analyser le fonctionnement d’un territoire sous l’angle des flux de matières et d’énergie qui le traversent et le caractérisent. Cette analyse est notamment menée à travers le concept du métabolisme territorial. Sous cet angle, les flux sont envisagés à la fois dans leur dimension matérielle et à la lumière des systèmes d’acteurs et des enjeux socio-économiques et politiques qui les influencent. L’écologie territoriale tend en cela à mettre en exergue des leviers de transition socio-écologique à l’échelle des territoires.Cette thèse propose la mise à l’épreuve de ces concepts à travers un terrain d’étude situé dans la moyenne vallée du Rhône. En remontant à la fin du XVIIIe siècle, la recherche souligne tout d’abord comment se met en place, à l’échelle de celui-ci, un régime socio-écologique fondé sur l’industrie et les infrastructures lourdes. Ensuite, à partir de l’analyse de quatre types de flux (énergétiques, hydriques, toxiques, alimentaires), la thèse propose de caractériser la manière dont ce régime se matérialise aujourd’hui dans le métabolisme. Ce métabolisme est alors qualifié d’intensif et de toxique – par l’intensité et la toxicité des flux mis en jeu – ainsi que d’absorbant – en ce qu’il assure des fonctions métaboliques répondant aux besoins d’autres territoires (traitement de déchets, production alimentaire). Les caractéristiques de ce métabolisme impliquent alors une faible capacité des acteurs locaux (habitants, acteurs publics, agriculteurs) à agir sur les flux pour leur réduction ou leur transformation. Pourtant, dans un contexte de mutations des systèmes productifs et de résidentialisation, plusieurs initiatives émergent de ces mêmes acteurs locaux pour comprendre et agir sur les flux de matière et d’énergie, dans une perspective de développement territorial durable. Celles-ci conduisent à des formes de remise en question des équilibres de pouvoir existants mais le régime socio-écologique industriel persiste, en partie en ce que les verrous qui le structurent et l’auto-entretiennent ne sont pas questionnés. / Territorial ecology is a research field which proposes to analyse the functioning of a territory under the perspective of the flows of matter and energy which passes by and characterize it. This analysis is particularly led through the concept of territorial metabolism. Through this lens, flows are considered in their material dimension but also under the light of the actor systems and of the political and socio-economic issues which influence them. Thus, territorial ecology tends to underline socio-ecological transition levers on the scale of territories.This thesis proposes to test these concepts through a field study in the mid Rhône valley. Looking back to the end of the 18th century, the research firstly underlines how a socio-ecological regime is progressively set around the industry sector and the heavy infrastructures at the scale of the territory. Then, the thesis describes how this regime gets materialized into today’s metabolism through the analysis of four different kinds of flows (energy, water, toxic elements, food). This metabolism is described as intensive and toxic – according to the level of intensity and toxicity of the flows at stake – as well as absorbing – in the way it deals with other territories’ metabolic functions (waste management, food production). These properties of the Rhône-Médian’s metabolism implicate limited capacity for local actors (inhabitants, public actors, farmers) to act towards the reduction or the transformation of these flows. However, within a context of change in production systems and of residentialisation, several local initiatives emerge. Through this process, local actors gain a better understanding and better capabilities to act on the flows of energy and matter in order to engage with sustainable territorial development. These local initiatives lead to several forms of reassessment of existing power relationships but the industrial socio-ecological regime remains, partly because some lock-ins which structure and self-sustain this regime are not questioned.

A diversidade beta pode ser definida como a mudança na composição de espécies entre locais em uma determinada área geográfica. Quantificar a contribuição relativa dos diferentes fatores que a afetam é essencial para entender como é mantida a diversidade das comunidades. Nosso estudo tem foco na vegetação lenhosa da região do Alto Camaquã, sul do Brasil (ca.30-31° S, 52-54° W), que está inserida no bioma Pampa e é caracterizada por ampla heterogeneidade ambiental com mosaicos de floresta e campo naturais. Com o objetivo de responder quais fatores tem mais influência na estruturação da comunidade de plantas lenhosas dessa região, distribuímos sistematicamente 60 unidades amostrais onde foram levantadas todas as espécies de plantas lenhosas. Primeiramente particionamos a diversidade beta através de RDA parcial e verificamos que as variáveis ambientais – que incluem variáveis climáticas, topográficas e edáficas – explicaram 28,4% da variação na composição de espécies, a distância geográfica explicou 16,6%, 14,7% foi compartilhado entre os dois componentes e 40,3% permaneceu não explicado. Com isso ficou claro que fatores determinísticos são mais importantes na estruturação das comunidades lenhosas. Em uma posterior análise de árvore de regressão multivariada, as variáveis climáticas foram selecionadas como as mais influentes. Além disso, a região de estudo é uma das mais bem conservadas do Estado. Portanto, em um segundo momento, investigamos a influência de fatores adicionais na diversidade beta das comunidades lenhosas, considerando o histórico de 300 anos de presença de manejo com pecuária familiar do Alto Camaquã. A partir de dados de um zoneamento agroecológico, exploramos a influência das diferentes tipologias de pecuária sobre dois estratos das comunidades de plantas lenhosas, plântulas e adultos, controlando o efeito da variação climática através de correlações matriciais. Encontramos que o manejo não está relacionado com o turnover de espécies de plântulas, contudo explica 12% da variação da diversidade beta de arbóreas. Concluímos, portanto, que a heterogeneidade climática da região gera heterogeneidade ambiental, sendo esta a principal determinante da diversidade das comunidades, apesar de processos neutros também influenciarem, em menor proporção. A presença do manejo não afeta de forma equitativa a comunidade de plantas lenhosas, contribuindo para a heterogeneidade florística da região. / Beta diversity can be defined as the shift in species composition among sites in a geographical area of interest. Quantifying the relative contributions of different processes that affect beta diversity is essential for understanding how diversity is maintained in communities. Our study focuses on the woody vegetation of the Alto Camaquã region, southernmost Brazil (c. 30-31° S, 52-54° W), which is within the domain of the Pampa biome and presents wide environmental heterogeneity showing natural forest-grassland patches. Aiming to answer which factors are most influential in the structuring of the woody plant communities, we systematically placed 60 sampling plots throughout the study area for vegetation survey. We partitioned beta diversity through partial RDA and verified that the environmental variables - which include climatic, topographic and edaphic variables - explained 28.4% of the variation in species composition, geographic distance accounted for 16.6%, 14.7% was shared between the two components and 40.3% of the variation remained unexplained. The deterministic processes are clearly the most important in structuring the woody communities. Further analysis using multivariate regression tree selected the climatic variables as the most influential. The study region shows a well conserved physiognomy, regardless of its 300-years history of land use for family cattleraising; hence in a second moment we investigated additional factors affecting diversity patterns of the plant communities surveyed, starting from available agroecological zoning data for land management. We explored the effect of the different typologies of family cattle-raising over two strata of the woody vegetation community, seedling and adult plants, controlling the effect of climate heterogeneity using matrix correlations (partial Mantel tests). We found that land management is not correlated with the species turnover of seedlings, yet explains 12% of the variation in the adult plants beta diversity. We concluded, hence, that climatic heterogeneity creates habitat heterogeneity, being the main determinant of community diversity, although neutral processes are also influent. Land management does not affect the woody plant community evenly, thus contributing to the floristic heterogeneity of the region.
