This paper presents a typology of ecological injustice hotspots for targeted design of nature-based solutions to guide planning and designing of just cities. The typology demonstrates how the needs and capabilities of nonhuman nature can be embedded within transitions to multi- and interspecies relational futures that regenerate and protect urban social-ecological systems. We synthesise the findings of previous quantitative and qualitative analyses to develop the Ecologically Just Cities Framework that (1) works as a diagnostic tool to characterise four types of urban ecological injustices and (2) identifies nature-based planning actions that can best respond to different types of place-based ecological injustices. 摘要 本文提出了一个生态不公正热点的类型学,用于有针对性地设计基于自然的解决方案,以指导公正城市的规划和设计。该类型学展示了非人类自然的需求和能力如何能够被嵌入到向多物种和跨物种关系的未来过渡中,从而再生和保护城市社会生态系统。我们综合了之前的定量和定性分析结果,制定了生态公正的城市框架,(1) 作为诊断工具来描述四种类型的城市生态不公正;(2) 确定了基于自然的规划行动,可以最好地应对不同类型的地方生态不公正问题。more » « less

null (Ed.)Abstract The scale, pace, and intensity of human activity on the planet demands radical departures from the status quo to remain within planetary boundaries and achieve sustainability. The steering arms of society including embedded financial, legal, political, and governance systems must be radically realigned and recognize the connectivity among social, ecological, and technological domains of urban systems to deliver more just, equitable, sustainable, and resilient futures. We present five key principles requiring fundamental cognitive, behavioral, and cultural shifts including rethinking growth, rethinking efficiency, rethinking the state, rethinking the commons, and rethinking justice needed together to radically transform neighborhoods, cities, and regions.more » « less

Abstract Recent years have seen a massive development of geospatial sensing systems informing the use of space. However, rarely do these sensing systems inform transformation towards urban sustainability. Drawing on four global urban case examples, we conceptualize how passive and active sensing systems should be harnessed to secure an inclusive, sustainable and resilient urban transformation. We derive principles for stakeholders highlighting the need for an iterative dialogue along a sensing loop, new modes of governance enabling direct feeding of sensed information, an account for data biases in the sensing processes and a commitment to high ethical standards, including open access data sharing.more » « less

The standard of care treatment for neovascular age-related macular degeneration, delivered as ocular injection, is based on anti-vascular endothelial growth factor (anti-VEGF). The course of treatment may need to be modified quickly for certain patients based on their response. Models that track both the concentration and the response to an anti-VEGF treatment are presented. The specific focus is to assess the existence of analytical solutions for the different types of models. Both an ODE-based model and a map-based model illustrate the dependence of the solution on various biological parameters and allow the measurement of patient-specific parameters from experimental data. A PDE-based model incorporates diffusive effects. The results are consistent with observed values, and could provide a framework for practitioners to understand the effect of the therapy on the progression of the disease in both responsive and non-responsive patients.more » « less
