Perceptions of Governance (Il)Legitimacy Mediate Climate Change Adaptation in the Lake Victoria Basin, Uganda

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Governance is a well‐known dimension of adaptive capacity across various frameworks, however specific links between perceptions of governance (il)legitimacy and adaptive capacity remain relatively unexplored. In this study, we investigate connections between climate change adaptation and perceptions of governance (il)legitimacy using focus ...

Seismic Fragility of Gravity and Semi‐Gravity Retaining Walls and Its Impact on the Functionality Loss of Road Infrastructures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls are key geotechnical components of road infrastructure, whose seismic performance directly affects the resilience of transportation networks. Despite their importance, seismic fragility models for retaining walls available in the literature refer only to specific case studies.
