Abstract Surface displacement caused by natural and anthropogenic activities poses a significant risk to subsurface pipelines, particularly in areas experiencing subsidence. Stress and strain induced by deformation can lead to pipeline buckling and potential vulnerability. This study applies a multidisciplinary approach integrating interferometric synthetic aperture radar (InSAR) deformation analysis, well data, and geological context to assess the risk to oil and gas pipelines in Iran’s Qazvin plain. The focus is on evaluating the impact of an unconfined aquifer, which has a lower risk of subsidence compared to a confined aquifer, on pipeline infrastructure. We analyzed multitemporal Sentinel-1 data collected between 2014 and 2021. Our findings reveal that 2,400 km 2 of the study area is experiencing subsidence with vertical rates reaching up to 14 cm/year with an average S k {S}_{{\rm{k}}} , or skeletal storage value of 0.04. We explore the reasons for this unexpectedly high subsidence, finding that compressible unconfined aquifers with historically low water levels are also at risk for significant inelastic, or permanent, subsidence. We also evaluate pipeline profiles, which show spatial subsidence, much higher than typically seen in unconfined aquifers, with variations of up to 1 m, indicating long-term risks to the infrastructure. This study demonstrates the potential of InSAR techniques in assessing the risk to critical infrastructure, such as oil and gas pipelines, in regions with land deformation due to groundwater withdrawal. Our approach underscores the importance of continuous monitoring and offers valuable insights for addressing the challenges posed by subsidence on pipeline infrastructure.

Biodiversity in human-dominated landscapes is declining, but evidence-based conservation targets to guide international policies for such landscapes are lacking. We present a framework for informing habitat conservation policies based on the enhancement of habitat quantity and quality and define thresholds of habitat quantity at which it becomes effective to also prioritize habitat quality. We applied this framework to insect pollinators, an important part of agroecosystem biodiversity, by synthesizing 59 studies from 19 countries. Given low habitat quality, hoverflies had the lowest threshold at 6% semi-natural habitat cover, followed by solitary bees (16%), bumble bees (18%), and butterflies (37%). These figures represent minimum habitat thresholds in agricultural landscapes, but when habitat quantity is restricted, marked increases in quality are required to reach similar outcomes.
