title: Infrastructure Climate Resilience Assessment Data Starter Kit for Tonga

description: This starter data kit collects extracts from global, open datasets relating to climate hazards and infrastructure
  systems.




  These extracts are derived from global datasets which have been clipped to the national scale (or subnational, in
  cases where national boundaries have been split, generally to separate outlying islands or non-contiguous regions),
  using Natural Earth (2023) boundaries, and is not meant to express an opinion about borders, territory or sovereignty.




  Human-induced climate change is increasing the frequency and severity of climate and weather extremes. This is causing
  widespread, adverse impacts to societies, economies and infrastructures. Climate risk analysis is essential to inform
  policy decisions aimed at reducing risk. Yet, access to data is often a barrier, particularly in low and middle-income
  countries. Data are often scattered, hard to find, in formats that are difficult to use or requiring considerable
  technical expertise. Nevertheless, there are global, open datasets which provide some information about climate
  hazards, society, infrastructure and the economy. This "data starter kit" aims to kickstart the process and act as a
  starting point for further model development and scenario analysis.



Hazards:


  
coastal and river flooding (Ward et al, 2020; Baugh et al, 2024)
  
extreme heat and drought (Russell et al 2023, derived from Lange et al, 2020)
  
tropical cyclone wind speeds (Russell 2022, derived from Bloemendaal et al 2020 and Bloemendaal et al 2022)



Exposure:


  
population (Schiavina et al, 2023)
  
built-up area (Pesaresi et al, 2023)
  
roads (OpenStreetMap, 2025)
  
railways (OpenStreetMap, 2025)
  
power plants (Global Energy Observatory et al, 2018)
  
power transmission lines (Arderne et al, 2020)



Contextual information:


  
elevation (European Union and ESA, 2021)
  
land-use and land cover (Copernicus Climate Change Service and Climate Data Store, 2019)
  
administrative boundaries from geoBoundaries (Runfola et al., 2020)




  The spatial intersection of hazard and exposure datasets is a first step to analyse vulnerability and risk to
  infrastructure and people.




  To learn more about related concepts, there is a free short course available through the Open University on
  Infrastructure and Climate Resilience.
  This overview of the course has more details.




  These Python libraries may be a useful place to start analysis of the data in the packages produced by this workflow:




  

    snkit helps clean network data
  
  

    nismod-snail is designed to help implement infrastructure
    exposure, damage and risk calculations
  




  The open-gira
  repository contains a larger workflow for global-scale open-data infrastructure risk and resilience analysis.




  For a more developed example, some of these datasets were key inputs to a regional climate risk assessment of current
  and future flooding risks to transport networks in East Africa, which has a related online visualisation tool at
  https://east-africa.infrastructureresilience.org/
  and is described in detail in Hickford et al (2023).
