A growing number of cities are preparing for climate change impacts by developing adaptation plans. However, little is known about how these plans and their implementation affect the vulnerability of the urban poor. We critically assess initiatives in eight cities worldwide and find that land use planning for climate adaptation can exacerbate socio-spatial inequalities across diverse developmental and environmental conditions. We argue that urban adaptation injustices fall into two categories: acts of commission, when interventions negatively affect or displace poor communities, and acts of omission, when they protect and prioritize elite groups at the expense of the urban poor.

The threat of flooding in cities is often compounded by political and economic decisions made on watershed management, land development and water infrastructure and provisioning. It has also become a point of conflict between cities’ objectives for development and modernization, and the struggles of marginalized residents living in low‐lying coastal and riverine areas to remain in place. Flooding takes on different forms depending on one's point of view. It is a biophysical issue, involving geology, geography, meteorology and ecology. It is one of urban governance, involving planning and maintenance of infrastructure and land use. And it is sociopolitical, involving historical social and spatial marginalization and contestation. This article, based on mixed‐methods research in Jakarta, Indonesia, traces the conceptual and physical contours of urban waterscapes across these conflicting ideas and narratives. It brings into dialogue theories of urban political ecology, landscape ecology and environmental ethnography to explore the interrelationships between biophysical and sociopolitical factors behind urban flooding. In the article the focus is on the varying materialities and scales involved, including the ecological scales of the watershed, the infrastructural scales associated with flood protection, and the urban scales of planning, governance and social activism. The article concludes with a proposition for a multidimensional approach to thinking and acting on problems of urban ecological change.

As climate change threats to urban centres become more alarming, cities are proposing ambitious plans to adapt to climate impacts. These plans are increasingly subsumed within urban development projects, and embedded in global flows of capital and networks of environmental governance and planning. And yet, scholarship on urban adaptation has tended to approach the city as an analytically bounded territory, neglecting interconnections across space and processes of globalisation, urbanisation, and geopolitics. This paper extends theories of relational geographies to explore the emerging conditions of urban adaptation in the context of climate change and globalised urban development. Focusing on the global links of Dutch water expertise, and tracing relationships within and between Rotterdam, New York, and Jakarta, it illustrates the formation of global-urban networks – the multiscalar, multilevel connections through which capital, knowledge, and influence flow. It probes the ways in which these networks emerge to mobilise ideas and influence across geographical scales and political boundaries, driven and defined by interrelated factors including economic relationships, historically defined situational relationships, and interface conditions including narratives of culture and environmental urgency. The paper introduces the concept of ‘network formation’ to see and understand such interconnected, relational processes. It explains the spatial and temporal interconnections within and across sites, and the relationships between urban spatial projects and broader political economies and ecologies. The paper asserts the importance of conceptualising the relationships and interfaces of increasingly mobile and interconnected urban environmental futures.
