Purpose: Value co-creation amongst project stakeholders is often necessary for situations where the expertises or resources required are beyond a single stakeholder. Certain project delivery models (PDMs) with strong emphasis on relationships and trust are especially suited to value co-creation approach by encouraging collaborations amongst stakeholders and innovations. However, anecdotal evidence suggests that value co-creation impacts positively on particular types of projects but not on others. The purpose of this paper is to investigate the effect of value co-creation on project performance (PP) and how the effect is moderated by requirements uncertainty (RU). Design/methodology/approach: Based on the data from a cross-sectional survey of 120 Chilean construction project managers, the study validated a conceptual framework on the moderated effects of value co-creation process. Findings: Value co-creation process underpinned through relational engagement, collaboration and innovativeness positively impacts on PP, and project’s RU moderates this relationship. Practical implications: The findings empirically show that collaborative PDMs are best suited to projects where requirements are uncertain. Identifying the most suitable delivery model for a given context can reduce the project’s risk of failure and help maximise project value. When RU is low, the co-creating value is less critical to PP; whereas, when RU is high, choosing a collaborative PDM is fundamental to superior PP. Originality/value: This study provides much-needed evidence on the effects of value co-creation process on PP. Additionally, it contributes to the literature by conceptualising and validating the moderated impact on PP by RU.

Australia’s residential sector faces mounting climate adaptation challenges. Residential buildings contribute over 10% of national carbon emissions and are increasingly exposed to intensifying extreme weather events, including bushfires, floods, and heatwaves. While previous reviews have examined specific mitigation strategies or impacts of individual hazards, no synthesis has traced how climate-resilient housing research has evolved across multiple hazard types and design approaches in the Australian context. This study addresses this gap through a longitudinal analysis of 36 peer-reviewed articles (2009–2025) identified via Scopus and analyzed thematically. The findings reveal a significant paradigm shift: early research (2009–2018) focused predominantly on energy efficiency and carbon mitigation through passive design and building performance optimization, whereas the recent literature (2019–2025) emphasizes comprehensive adaptation frameworks integrating hazard-specific resilience strategies, technological innovations, and socio-political considerations. This synthesis identifies emerging priorities, informing future research agendas and evidence-based policymaking for climate adaptation in Australia’s residential sector.

Climate change amplifies urban sustainability challenges, with intensifying sand and dust storm (SDS) hazards highlighting the important role of Ecosystem wind erosion prevention (EWEP) as an ecosystem service (ES). In northern China, a region prone to wind erosion, EWEP mitigates aeolian processes at sand sources and reduces downwind dust transport to urban centers. This study employs the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model to simulate diffusion dynamics of EWEP and to assess its hazard mitigation effects for cities in northern China. The findings are as follows: (1) EWEP capacity increased consistently from 2000 to 2024; (2) Aggregated preventive benefits rose, which aligns with the interpretation that systemic ecological restoration reduces dust dispersion; (3) Preventive benefits exhibit stratification across different urban agglomerations. These findings can inform SDS risk management and climate adaptation strategies to support urban sustainability.
