In the context of accelerating climate change and increasing pressure on natural resources, agriculture needs to rethink its operating models to ensure both sustainability and long-term stability. The circular economy (CE) is increasingly invoked as a possible solution, but its concrete contribution to the climate resilience of agricultural systems remains insufficiently integrated and often assessed in a fragmented manner. This study aims to analyze the role of circular strategies in strengthening the climate resilience of agriculture, through a systemic approach based on multiple indicators. The methodology is based on a structured and comparative analysis of recent scientific literature, complemented by a bibliometric and co-occurrence analysis of keywords, in order to identify the main research directions and evaluation methods used. The analyzed indicators cover dimensions related to soil, water, crop performance, energy and socio-economic resilience of farms. The results suggest that circular economy strategies may contribute to climate resilience through cumulative, and context-dependent effects, including improvements in soil quality, resource-use efficiency, and reduced dependence on external inputs. However, evidence regarding direct impacts on production stability and adaptive capacity remains heterogeneous and often indirect. The study contributes by proposing an integrated conceptual framework that highlights the systemic nature of climate resilience and its links to decarbonization pathways, providing a basis for future empirical research and policy development.

Growing wastewater volumes and intensifying water scarcity are driving the need for affordable, sustainable solutions that enable safe urban water reuse and strengthen climate resilience. Policy frameworks such as SDG6 and EU water reuse requirements highlight that reclaimed water must meet strict environmental and public health standards. In contrast, conventional biological treatment cannot fully remove many emerging contaminants, underscoring the need for advanced treatment approaches that consistently deliver high-quality reclaimed water. In this context, this review examines the role of membrane technologies (MF, UF, NF, RO, FO) and membrane bioreactors (MBRs) in providing safe water in urban environments and in enhancing urban climate resilience, including decentralized systems and advanced reclamation needs. It also discusses the contribution of membrane-based solutions to sustainable cooling systems and heat-stress mitigation, as well as the integration of membrane technologies into green infrastructure and nature-based solutions for climate adaptation. Technical and economic performance is shaped by fouling, cleaning requirements, and energy use, making life-cycle and operational optimization critical for long-term sustainability. Case studies and EU-funded initiatives demonstrate that, with appropriate governance and design, membrane-based approaches can enable reliable reclaimed water supply, enhance water security, and contribute to circular urban water management. The analysis was based on peer-reviewed open-access publications, which may introduce a degree of selection bias.
