Can multi-scale thermal infrared imaging help validate and monitor water stress in alluvial forests?
Published: 2024-04-13
Subjects: Geomorphology, Physical and Environmental Geography, Remote Sensing, Terrestrial and Aquatic Ecology
Alluvial forests are fragile and sensitive to drought induced by climate change and exacerbated by altered flow regimes. Our ability to detect and map their sensitivity to drought is therefore crucial to evaluate the effects of climate change and adjust management practices. In such a context, we explore the potential of multi-scale thermal infrared imagery (TIR) to diagnose the sensitivity of [...]

Global trade and the resilience of food supply to extreme weather exposure
Published: 2023-08-31
Subjects: Agriculture, Physical and Environmental Geography, Sustainability
Climate change is increasing the risk of extreme weather events, potentially threatening crop yields and global food security. A key benefit of international free trade is risk sharing, because global aggregate production is more stable than that of individual countries which may be adversely affected by extremes. Here we test the hypothesis that diverse sourcing of crops from multiple trading [...]

The modern world uses predictive computer models for many important purposes, including weather predictions, epidemic management, flood forecasting and warnings, and economic policymaking. We need to know how much we can trust the projections of these models, not only to achieve more accurate projections for systems, but also to undertake scientific learning about systems by incrementally testing [...]
A high-resolution temporal framework to understand the reach-scale controls on wood budgeting
Published: 2023-04-07
Subjects: Environmental Monitoring, Geomorphology, Hydrology, Physical and Environmental Geography, Remote Sensing
Large active channels usually store more wood than channels with a narrow flow because of the availability of large unvegetated bars for wood deposition and inner functioning that usually supplies more wood through channel shifting. However, the dynamics of the wood supply (wood input, output, or stability) can vary substantially over time and the drivers are largely unknown. To explore them, we [...]
Rapid seaward expansion of seaport footprints worldwide
Published: 2023-02-25
Subjects: Civil Engineering, Geographic Information Sciences, Geomorphology, Other Environmental Sciences, Physical and Environmental Geography, Remote Sensing, Sustainability
As global maritime traffic increases, seaports grow to accommodate and compete for higher volumes of trade throughput. However, growth trajectories of seaport footprints around the world have gone unmeasured, likely because of a lack of readily available spatio-temporal data. Here, we use geospatial analysis of global satellite imagery from 1990–2020 to show that 65 seaports among the world's top [...]
