“…First, a fire that occurs near a farm in the hinterlands could cause excessive smoke that shuts down roadways and disrupts the transport of food to the city (OECD 2020, Wetterberg et al 2021). Later, the land scarred by the initial fire might experience heavy precipitation, causing PFDF that runs into the farm itself and destroys crops, thus reducing the amount of food available to a nearby city (Bera et al 2021, Petrova 2022. While the final impact is the same-food supply to a city is disrupted-the pathways and timelines of impact stemming from the initial fire play out very differently.…”

“…Fires can also cause smoke that reduces generation capacity of solar photovoltaic systems (Donaldson et al 2021). PFDFs can cause physical damage to transmission lines (Petrova 2022). Electricity supplied by hydroelectric plants can diminish if precipitation is too low (Kreimer et al 2003).…”

“…Physical communication infrastructure (e.g. cellular towers, data centers, long-haul fiber cables, electrical support facilities) can be directly damaged by fire (Hirsch and Fuglem 2006, Chang 2016, Anderson et al 2020, flooding (Zimmerman and Faris 2010, Chang 2016, Padmanabhan et al 2019, and PFDF (Chang 2016, Petrova 2022. While communication infrastructure tends to be clustered in urban areas, large data centers can be found in hinterlands, such as the world's largest data center market in northern Virginia near Washington D.C. (Chowdhury et al 2013, Federal Communications Commission 2021, Barkham and Whelan 2022.…”

“…Smoke, soot, and ash from fires can travel through the water system from the hinterlands to urban areas and require flushing and boiling of residential water to ensure its potability (Sham et al 2013, Kolden andHenson 2019). PFDFs can damage or clog components of water distribution networks, including pipelines, well heads, reservoirs, and storage tanks (Sham et al 2013, Petrova 2022. Sediment buildup in reservoirs can greatly reduce the planned life of the reservoir (Sham et al 2013).…”

“…Flooding can cause oversaturated soils, drowning and destroying crops (Derbile andKasei 2012, Calzadilla et al 2013). PFDF has been shown to damage farmland or farm facilities by depositing rocks or sediment which can bury crops and damage buildings or equipment (Bera et al 2021, Petrova 2022. Any decrease in or destruction of hinterland crop yields can reduce the quality or quantity of food sent to urban centers, which is especially problematic since cities today are heavily reliant on outsourcing food.…”

Extreme weather-related events are showing how infrastructure disruptions in hinterlands can affect cities. This paper explores the risks to city infrastructure services including transportation, electricity, communication, fuel supply, water distribution, stormwater drainage, and food supply from hinterland hazards of fire, precipitation, post-fire debris flow (PFDF), smoke, and flooding. There is a large and growing body of research that describes the vulnerabilities of infrastructures to climate hazards, yet this work has not systematically acknowledged the relationships and cross-governance challenges of protecting cities from remote disruptions. An evidence base is developed through a structured literature review that identifies city infrastructure vulnerabilities to hinterland hazards. Findings highlight diverse pathways from the initial hazard to the final impact on an infrastructure, demonstrating that impacts to hinterland infrastructure assets from hazards can cascade to city infrastructure. Beyond the value of describing the impact of hinterland hazards on urban infrastructure, the identified pathways can assist in informing cross-governance mitigation strategies. It may be the case that to protect cities, local governments invest in mitigating hazards in their hinterlands and supply chains.

The utilization of baffle structures as a highly effective strategy for mitigating debris flow has attracted significant scholarly attention in recent years. Although the predominant focus of existing research has been on augmenting the energy dissipation capabilities of baffle structures, their deformation behavior under impact load has not been extensively investigated. Addressing this research gap, the current study systematically designs a series of physical model experiments, incorporating variables such as baffle height, shape, and various combinations of baffle types to comprehensively analyze the deformation characteristics of baffles subjected to debris flow impact. The experimental results reveal that the deformation of baffle group structures demonstrates a marked non-uniform spatial distribution and exhibits a latency effect. Additionally, distinct baffle configurations show considerable variations in peak strain, suggesting that combining different baffle shapes can not only optimize energy dissipation but also enhance resistance to deformation. Moreover, the relationship between baffle height and the development of deformation in relation to energy dissipation capacity is inconsistent, indicating that deformation must be a key consideration in the design of baffle structures. Consequently, this paper advocates for the formulation of a deformation-based design strategy for baffle structures, with the findings presented herein providing a foundational reference for future studies.
