One of the problems urban areas are facing is the coupled effect of climate change and the Urban Heat Island (UHI) effect. This article attempts to demonstrate the potential of spatial planning to reduce the UHI effect and, hence, to contribute to climate change adaptation in compact urban areas. After a brief review of the relevant literature, the article focuses on one case study within the compact urban area of the city of Thessaloniki. The geographical, socio-economic and urban form data of the study area and its subsequent vulnerability to UHI were initially assessed. Based on these features, a local spatial planning strategy is proposed, and the study proceeds to a detailed amendment of the land use plan, within part of the vulnerable zone. This takes into account the existing urban form, the lack of resources and the availability of the spatial planning tools within the Greek spatial planning system. Τhe main purpose of this article is to highlight the fact that, even in urban areas where the potential for intervention seems to be marginal, because of their existing form, the complexities of the local planning system and resource limitations, improvements to the UHI effect and adaptation to climate change can be achieved by better land use planning and urban design.

Cities are nowadays faced with an unprecedented crisis, due above all to the impacts of climate change and the increasing social inequalities, which require innovative approaches and more effective tools. Resilience is widely interpreted as a key principle to re-frame urban policies, paving the way to cross-sectoral urban strategies capable of better coping with contemporary challenges. This contribution focuses in particular on the 100 Resilient Cities (100RC) Initiative, launched by the Rockefeller Foundation and addressed to support cities all over the world in developing and implementing strategies capable of increasing urban resilience in the face of multiple shocks and stresses, including climate change. In detail, based on the comparative analysis of two case studies, Rome and Athens, this paper aims at providing insights on the main strengths and weaknesses of cities’ resilience-building processes developed under the 100RC Initiative and at deeply analyzing the contribution of the delivered Resilience Strategies to the improvement of cities’ capacities to cope with contemporary challenges and above all with the increasing impacts of climate change.

As climate change and other interdependent challenges are expected to become increasingly acute and unpredictable, so the need for policies and measures to reduce risks and uncertainties in order to adapt to these changes becomes more imperative. Cities can influence their adaptation, resilience, and eventually their sustainability through spatial planning with the use of more ecosystem-based planning tools, such as Green Infrastructure (GI). The present paper is an attempt to assess whether and how city strategies address the objective of an adaptation which interconnects the criteria of vulnerability, adaptability, and resilience through spatial planning. For this purpose, the paper examines the Resilience Strategies of seven European cities of the 100 Resilient Cities initiative (100RC). Based on a thematic analysis, the paper investigates whether these strategies incorporate a spatial planning approach which contributes to adaptation to climate change, focusing on GI as a spatial planning tool. The paper argues that there is room for improvement in all the examined strategies, as none of them fully incorporate the concept of GI, and, furthermore, that some critical planning principles which contribute to adaptation are missing.

Climate change adaptation has become an important policy domain, as it has the potential to substantially reduce many of the adverse impacts of climate change. Several scientific terms and general concepts have been used to comprehend adaptation, including vulnerability, exposure, sensitivity, adaptability, and resilience. However, most of these concepts are often used in inconsistent ways and their relationship is to a large extent unclear. As a result, there is a lack of clear understanding of adaptation and its practical implementation in fields such as spatial planning, whose role in tackling climate change, especially through ecosystem approaches, is critical. This paper attempts to investigate the practical integration of adaptation in the context of spatial planning, specifically through Green Infrastructure (GI) planning. Applying a thematic analysis to 91 scientific and major policy documents, the main determinants of the critical concepts that relate to adaptation were identified, classified, and intertwined with key determinants of GI planning and design. The analysis led to the development of a methodological tool, named REAd GrIn. This model can be used to prepare and evaluate spatial plans and policies, which integrate the concepts of resilience, vulnerability, and adaptability to achieve adaptation through spatial planning.
