Land use and land cover changes in São Paulo Macro Metropolis and implications for water resilience under climate change

The São Paulo Macro Metropolis (MMP) is a geographical arrangement that brings together the most significant Brazilian socioeconomic figures and faces numerous challenges, such as heavy pressure on natural resources. Through compilation, spatialization and cross-referencing of data, this work assessed time series of land use and land cover of the last decades, the water supply status in an urban environment and climate data projection for MMP. Municipalities with different profiles were identified: those with positive final balances and those with negative final balances about the maintenance of their natural areas. Furthermore, more than half of the municipalities of the MMP have low water supply assurance, which can be aggravated due to climate change, as predicted in several climate models. The characterization of municipalities based on this information allowed identifying which of them are the most vulnerable, and these results indicate paths for coordinated actions at local and regional levels to increase water resilience in the macro-region.The São Paulo Macro Metropolis (MMP) is a geographical arrangement that brings together the most significant Brazilian socioeconomic figures and faces numerous challenges, such as heavy pressure on natural resources.

Strategies for the planning of sustainable mobility: An exploratory study in Brazil

O crescimento acelerado da população nas cidades brasileiras, aliado à falta de um planejamento urbano adequado, tem o problema da mobilidade urbana como uma de suas consequências mais aparentes. O artigo aborda os impactos da expansão urbana na mobilidade para o município de São José dos Campos/SP. A falta de integração entre os diferentes modais e os impactos causados no transporte urbano no cenário municipal são os principais pontos que motivam este estudo. Assim, o objetivo do trabalho foi compreender e estruturar esta situação problemática e propor ações estratégicas, com vistas à promoção da mobilidade urbana sustentável naquele município. Para isto, será adotada uma abordagem multimetodológica que consistirá na combinação dos Mapas Cognitivos com o SCA (Strategic Choice Approach), apoiado pela utilização da matriz GUT (Gravidade/Urgência/Tendência). Como resultado foi possível definir um pacote de compromissos de decisões e ações estratégicas, que visem melhorar a infraestrutura de transporte atual e preparar o município para futuras atualizações, já considerando a multimodalidade como alternativa.The accelerated population growth in Brazilian cities, together with the lack of adequate urban planning, has the problem of urban mobility as one of its most apparent consequences. The article discusses the impacts of urban expansion on mobility for the city of São José dos Campos / SP. The lack of integration between the different modalities and the impacts caused in urban transport in the municipal scenario are the main points that motivate this study. Thus, the objective of the work is to understand and to structure this problematic situation and to propose strategic actions, in order to promote sustainable urban mobility in that city. For this, a multi-method approach is adopted, which consists of a combination of Cognitive Maps with the Strategic Choice Approach (SCA), supported by the use of the GUT (Severity / Urgency / Trend) matrix. As a result, it was possible to define a package of commitments for strategic decisions and actions, which has for its purpose to improve the current transportation infrastructure and to prepare the city for future upgrades, considering multimodality as an alternative
