1. Introduction
The Internet of Things (IoT) is a transformative technology that connects networked devices capable of collecting and exchanging data, enabling real-time monitoring and control across all industries. IoT is being applied in agriculture, healthcare, energy and urban infrastructure, offering efficiency improvements and automation on a global scale [
1,
2]. There are several types of outdoor IoT devices, such as cameras, sensors, routers, actuators, Pos terminals and Sim cards, which are widely used in sectors such as agriculture, transport and infrastructure. These devices are crucial for real-time monitoring but are vulnerable to extreme weather conditions. Their importance is emphasised in this research paper on the ability of IoT devices to withstand weather threats and prevent failures in harsh conditions. By connecting devices to central systems, IoT enables data-driven decision-making and has the potential to revolutionise sectors that rely heavily on environmental monitoring and resource optimisation. In Kazakhstan, a country known for its vast territory, diverse topography and extreme weather conditions, IoT systems play a critical role in monitoring environmental parameters, managing urban infrastructure, optimising agricultural activities and energy consumption [
3].
However, the reliability and sustainability of these IoT systems face significant challenges in the context of climate change, especially in regions with extreme weather conditions. Kazakhstan’s climate is characterised by strong seasonal and regional temperature fluctuations: temperatures can drop to −44 °C in the northern regions in winter and reach +45 °C in the southern desert regions in summer [
4]. Such extreme temperature ranges can pose operational risks for IoT devices as most of them, such as sensors, cameras, actuators, routers and SIM cards, are designed for certain acceptable environmental conditions. Constant exposure to prolonged summer heat, winter frost and unpredictable temperature fluctuations can lead to device malfunctions, inaccurate sensors and shortened device lifetimes, jeopardising the reliability of these critical systems [
5]. In arid and desert climates, overheating and dust accumulation have been identified as key risks for sensor reliability [
6].
Climate projections for Kazakhstan indicate not only an increase in average temperatures, but also an increase in the frequency of extreme events, including increased heat waves in summer, severe cold in winter, and unpredictable seasonal transitions. These predictions highlight the urgent need to consider how IoT systems will be able to withstand these conditions. Without proper adaptation, IoT infrastructure can fail anywhere, disrupting critical functions such as agricultural monitoring, power grid management, and urban traffic management [
7]. This potential vulnerability emphasises the need for a robust climate risk assessment for IoT infrastructure in Kazakhstan.
This paper addresses the need to quantify climate risks for IoT devices by developing risk assessment curves and climate risk models. While IoT technologies offer promising solutions to improve efficiency and automation, their resilience to climate extremes—especially in vulnerable and unstable regions such as Kazakhstan—is still poorly understood. A deep understanding of climate impacts on IoT systems is critical to building a robust infrastructure that can withstand expected climate stresses, ensuring the efficiency and durability of IoT-enabled services in Kazakhstan.
The Representative Concentration Pathways (RCPs) are widely used climate models developed by the Intergovernmental Panel on Climate Change (IPCC) to represent different greenhouse gas concentration pathways and their potential impacts on global climate [
8]. These pathways range from RCP2.6, which involves high mitigation efforts and low greenhouse gas emissions, to RCP8.5, a scenario with high emissions and minimal mitigation. These pathways are important for understanding future climate projections and developing adaptation strategies, such as resilience of Internet of Things (IoT) devices.
This study considers RCP4.5 and RCP8.5 scenarios with medium and high emissions. These scenarios are particularly relevant for Kazakhstan and the Central Asia region, as they contain projections of changes in temperature and precipitation that may affect the functionality and resilience of IoT systems. Climate projections derived from these scenarios are the basis for assessing potential environmental risks and planning necessary adjustments to IoT infrastructure.
To model these risks, we used the historical climate data from the Climate Data Store, in particular, monthly average ERA5 data (from 1940 to present) and monthly average land ERA5 data (from 1950 to present). Using this data, we developed the risk curves based on the failure rate of IoT devices as a function of temperature deviation from the normal range. These risk assessments will help identify critical thresholds at which the performance of IoT devices may degrade or fail, enabling the development of adaptation strategies that support the resilience of IoT systems in the face of climate variability [
4]. By establishing these thresholds, the study provides recommendations for adaptation measures and resilience planning necessary to ensure the continuity and functionality of IoT systems under future climate projections.
3. Methodology
This study employs a mixed-methods approach, integrating climate projection data with qualitative insights from interviews to develop a climate risk model for IoT device resilience in Kazakhstan. The methodology is organised into four key steps: data collection, device selection, climate risk modelling and data processing and visualisation. These steps are designed to quantify the impact of extreme weather on IoT devices and propose adaptation strategies based on identified vulnerabilities.
3.1. Climate Data Collection
We used two main datasets:
ERA5 Reanalysis (Copernicus Climate Data Store):
Resolution: 0.25° × 0.25° (approx. 30 km), hourly to monthly.
Period: 1940–2023.
Variables: near-surface temperature, relative humidity, precipitation, solar radiation, snow depth, and wind speed at 10 m.
Format: NetCDF (float32 datatype, gridded time series).
Processing: Bias correction was applied by comparing with the national meteorological station data.
CMIP6 Climate Projections:
Scenarios: RCP4.5 (stabilisation) and RCP8.5 (high emissions), with SSP5-8.5 used for extreme scenario analysis.
Period: 1950–2100.
Resolution: 0.5° × 0.5°, monthly means, downscaled for Kazakhstan.
Variables: same as ERA5 for consistency.
Data Type: NetCDF multidimensional arrays.
These datasets provided the quantitative basis for estimating the resilience of IoT devices to projected climate extremes.
We used climate projection data from the Coupled Model Intercomparison Project Phase 6 (CMIP6) to estimate the resilience of IoT devices to future climate extremes in Kazakhstan. CMIP6, the core dataset underpinning the 6th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), is an extended collection of global climate simulations. These simulations are the result of collaboration between leading climate research institutes using state-of-the-art general circulation models (GCMs). CMIP6 data allow us to explore important scientific questions such as the predictability of the climate system, quantification of future climate change impacts, and uncertainties associated with different socioeconomic and emissions scenarios.
In particular, we used data from the SSP5-8.5 scenario, a high-emissions scenario characterised by rapid economic growth, high dependence on fossil fuels and minimal climate change mitigation. This ‘business-as-usual’ scenario is particularly useful for studying the extreme impacts of climate change because it predicts large increases in global temperature, more frequent and intense heat waves, more intense cold waves, and greater seasonal variability. These factors overlap with critical stressors for IoT devices in Kazakhstan, a region already exposed to extreme climate variability. All figures were created using Python, specifically using libraries like Matplotlib and NumPy. First, we loaded the climate data from a NetCDF file with netCDF4, then extracted key variables like temperature, latitude, and longitude. Then, we selected a specific time period from the data and used a contour plot to visualize the temperature distribution.
The CMIP6 dataset used in this study includes two-dimensional and three-dimensional climate variables with high spatial and temporal resolution. These variables can be adapted to specific regions and periods to focus on different climate zones in Kazakhstan, from dry steppes to cold mountainous regions. SSP5-8.5 data were integrated into our climate risk models to estimate the probability of IoT device failure under different environmental conditions. For example, extreme temperatures exceeding operating thresholds can cause sensors, cameras and other IoT devices to malfunction or even fail. Similarly, high humidity or extreme temperature fluctuations can lead to condensation and degradation of materials, further limiting the functionality of devices.
To evaluate the potential impact of climate change on IoT devices in Kazakhstan, climate projections from CMIP6 models based on the RCP4.5 and RCP8.5 scenarios were used [
8].
Table 1 below summarises the key climate data, including changes in temperature and precipitation, used in the modelling to predict future conditions.
Risk curves help identify critical thresholds, for example, points where the probability of failure increases dramatically if climate conditions differ from the normal range. For IoT sensors used for agricultural monitoring, for example, a temperature deviation of ±10 °C from the design range can significantly increase the probability of failure and require additional protective measures such as isolation mechanisms or cooling.
3.2. IoT Device Selection and Priorities
The selection of IoT devices was based on their relevance to Kazakhstan’s critical sectors: agriculture, energy, transport, and urban infrastructure. We prioritised devices widely deployed outdoors, where exposure to climate stress is highest.
Selection priorities included: relevance to national infrastructure (agricultural sensors, energy monitoring devices, POS terminals); exposure to harsh outdoor conditions (routers, cameras, actuators); sectoral representativity (covering at least one device type from each critical sector); comparability with international studies to allow benchmarking of resilience strategies.
Regarding connectivity devices, we initially included SIM cards because they remain widely used in Kazakhstan. However, we acknowledge the transition toward e-SIM technology, which may provide improved durability and flexibility. This aspect is now discussed in the revised manuscript to reflect technological trends and alternatives.
The representative IoT devices evaluated in this study included Hikvision DS-2CD Series cameras (Hangzhou Hikvision Digital Technology Co., Ltd., Hangzhou, China), Siemens IoT2040 gateways (Siemens AG, Munich, Germany), and Bosch BME280 environmental sensors (Robert Bosch GmbH, Gerlingen, Germany). These devices were chosen as reference models due to their similar environmental specifications and widespread industrial use across agriculture, transport, and energy sectors in Kazakhstan. Their inclusion ensures that the resilience assessments reflect practical, real-world operating conditions for commonly deployed IoT hardware.
3.3. IoT Device Operating Conditions
Based on the climate risk projections described above, it is important to determine the operating conditions and performance thresholds of the IoT devices used in this study.
Table 2 below summarises the typical operating ranges of these devices, including cameras, sensors, actuators and others, to determine risk assessment thresholds and identify environmental factors that may affect device functionality in future climate conditions. The operating temperature ranges are based on manufacturer specifications for each IoT device type. Differences between ranges reflect design considerations: devices intended for outdoor use (e.g., sensors, cameras) are manufactured with wider tolerances to withstand environmental stress, while devices primarily used in sheltered settings (e.g., POS terminals) have narrower ranges.
By combining high-resolution CMIP6 climate projections, we extended these risk models to estimate the future probability of failure based on predicted conditions, such as the increase in intensity of heat waves by mid-century. The integration of CMIP6 data also allowed us to create a spatial map of these risks across Kazakhstan, highlighting the region most prone to IoT device failures. Such maps are essential for policymakers and stakeholders to prioritise resilience building in critical sectors such as agriculture, energy and transport.
Overall, the use of CMIP6 data, particularly the SSP5-8.5 scenario, provided a solid basis for understanding the potential impacts of extreme climate scenarios on IoT devices in Kazakhstan. The combination of climate projections, modelling of device failure probability and regional mapping provides practical insights to help industry adapt IoT systems to the challenges of climate change.
Another data collection method used in this research is the qualitative data from interviews. To contextualise the quantitative data, we conducted interviews with related organisations, including IoT developers, climate scientists, and professionals in sectors reliant on IoT devices, such as transportation, logistics, and agriculture. These interviews provide insights into the specific operational challenges faced by IoT devices in Kazakhstan’s climate, as well as current adaptation strategies and potential areas for improvement. Interview responses were conducted thematically, with a focus on identifying common concerns related to temperature fluctuations, device maintenance, and reliability in extreme weather conditions.
The second step involves data analysis. We will first discuss statistical methods for analysing climate trends, followed by a thematic analysis of interview data.
The historical and projected climate data from ERA5 are subjected to statistical analysis to identify trends in temperature extremes, seasonal shifts, and precipitation patterns. This analysis includes calculating mean, minimum, and maximum values, as well as examining variability across different regions [
25]. Given Kazakhstan’s distinct climate zones, regional analysis is essential for capturing localized impacts. Statistical tests, such as
t-tests or Mann–Kendall trend tests, are used to verify the significance of observed changes in climate variables over time.
The thematic analysis method was used to analyse the interview data.
Interview data is analysed using thematic coding to extract recurrent themes regarding IoT resilience issues. Key themes include temperature thresholds for device failure, challenges related to power supply in remote areas, and maintenance difficulties during extreme weather events. This qualitative analysis supports the quantitative findings by offering a grounded perspective on how climate conditions impact IoT functionality in the organisations in Kazakhstan.
3.4. Climate Risk Modelling
The next important step is to conduct climate risk modelling. How was the development of risk estimate curves carried out? The core of this study’s analysis involves developing risk estimate curves, which quantify the probability of IoT device failure under varying climate conditions. Using historical climate data, we define threshold values for environmental variables, such as temperature and humidity, beyond which device performance is likely to degrade. These thresholds are determined based on both literature [
25] and the operational parameters of IoT devices obtained from industry reports [
9].
We developed risk curves based on device operating ranges and climate variables. Probability of failure was calculated as:
where f(x) is the kernel density estimation (KDE)-based probability density function of temperature or humidity, and R is the device’s operating range. Sensitivity tests were conducted with threshold shifts of ±5 °C and ±10% humidity.
The risk estimate curves are constructed by mapping device performance data against temperature and humidity thresholds. For example, sensors may operate optimally within a specified temperature range, but performance may decline or fail entirely as temperatures exceed these limits. By using failure probability distributions, we create curves that illustrate the likelihood of device failure as climate variables deviate from baseline operational ranges.
How did we conduct the validation and sensitivity testing? To ensure the accuracy of the risk estimate curves, we conduct sensitivity testing by adjusting input variables and assessing the resulting changes in failure probability. This step allows us to understand the robustness of our model and identify the environmental conditions that most significantly affect device reliability. Validation of the model is performed using cross-validation techniques, where data subsets are analysed separately to compare the consistency of risk estimates.
Next is the time for the Integration with Climate Projections; let us discuss this. Finally, to forecast the future impact of climate change on IoT devices, we integrate ERA5 climate projections into the model. By applying projected climate scenarios to the risk estimate curves, we assess how the likelihood of device failure may change under predicted climate conditions. This integration enables a forward-looking analysis, providing estimates of IoT reliability under potential future scenarios, such as increased frequency of heatwaves or colder winter extremes.
3.5. Data Processing and Visualization
The final important step is mapping and visualization. To effectively display the spatial distribution of climate risks, data analysis and visualization, Python (version 3.11) was used. Beyond Matplotlib (3.8.0) and NumPy (1.26.0), the following libraries were employed:
Pandas (1.26.0) (data handling, time series analysis).
netCDF4 (1.6.4) (extraction of ERA5 and CMIP6 NetCDF files).
Seaborn (0.13.0) (statistical plotting, KDE).
SciPy (1.11.3) (statistical tests: t-test, Mann–Kendall trend analysis).
Cartopy (0.22.0) (geospatial mapping with correct projections and scale bars).
All figures were revised to include error bars, improved legends, probability density function (PDF) definitions, and professional cartographic standards for maps. By leveraging Python’s data visualization libraries, we overlaid risk data onto regional maps, illustrating which areas are most likely to experience operational challenges with IoT devices. These visualizations emphasize regions vulnerable to climate impacts, helping policymakers and industry stakeholders prioritize areas for resilience planning and adaptation investments.
4. Analysis and Results
As this research paper employed both quantitative and qualitative data collection methods to analyse the climate risks affecting IoT devices in Kazakhstan, the integration of statistical climate data and insights from interviews provided an understanding of the operational challenges, adaptation strategies, and potential risks IoT devices face in the context of Kazakhstan’s varied climate conditions.
To complement the quantitative climate projections, we collected qualitative data through semi-structured interviews designed to capture sector-specific insights into IoT resilience under extreme weather conditions.
Timing: Interviews were conducted between May 2023 and February 2024.
Participants: A total of 20 respondents participated, representing a balance of IoT developers, sector specialists, and managers in the fields of agriculture, transport, energy, and logistics.
Rationale for sector selection: These sectors were prioritized because they rely heavily on outdoor IoT devices that are directly exposed to Kazakhstan’s harsh climate, making them highly vulnerable to weather-related disruptions.
Representativity: Participants were chosen to provide diverse perspectives, ensuring coverage of both technical experts (who understand device performance and limitations) and operational managers (who face real-world deployment and maintenance challenges).
Extreme weather experience: The majority of respondents had direct experience with device failures or operational disruptions during heatwaves, severe frosts, snow accumulation, or dust storms.
IoT adoption stage: Respondents included both current users of IoT devices (e.g., agricultural sensors, smart irrigation systems, power grid monitors) and organizations planning future IoT integration, enabling the study to capture both present challenges and anticipated risks.
Analysis approach: Interview transcripts were thematically coded, focusing on:
Climate-related device failures (battery issues, sensor inaccuracies, casing damage).
Maintenance and calibration challenges in remote or extreme environments.
Sector-specific resilience strategies, including redundancy, weatherproofing, and predictive maintenance.
This qualitative dataset complements the climate modelling by grounding statistical risk curves in the lived experiences of practitioners and ensuring that the resilience framework reflects both scientific projections and operational realities.
The analysis of historical and projected climate data from ERA5 revealed significant trends in temperature extremes, seasonal shifts, and precipitation patterns across different regions of Kazakhstan. To visualize the temperature distributions across different regions of Kazakhstan, we created a graph for temperature distribution and risk zones. This was also done to assess the potential risk zones for IoT device operation under both historical and future climate scenarios. By plotting the probability density of temperatures and highlighting areas that fall outside the operational limits of IoT devices (e.g., −30 °C to +30 °C), the graph provides a clear representation of where and when devices are most vulnerable to extreme weather conditions. This method allows for a detailed analysis of the climatic stresses on IoT devices, helping to identify high-risk areas and facilitating the development of targeted resilience techniques to avoid device failure in extreme climates (
Figure 1). This graph illustrates regions of Kazakhstan where temperatures are likely to exceed the operational limits of IoT devices, increasing the risk of failure. The probability density highlights the frequency of extreme temperatures and regional climatic variations. This information helps identify high-risk areas and prioritize resilience strategies, such as protective measures and alternative deployment options to ensure device functionality in extreme weather. This localized analysis provided insights into how different IoT devices might perform in response to specific regional climate conditions.
Next, we compare temperature probability density functions for four regions of Kazakhstan-north, south, east and west—using the Kernel Density Estimation (KDE) method to smooth temperature distributions. By plotting these curves, the graph visualises regional climate changes and highlights temperatures that are outside the operating limits of IoT devices (−30 °C to +30 °C). This allows us to visualize a comparison of how a region’s climate can affect the functionality of IoT devices and identify high-risk areas that require targeted resilience strategies to mitigate the impact of extreme temperatures (
Figure 2).
Figure 3 represents temperature distributions for historical and projected climate scenarios in different regions of Kazakhstan. The Kernel Density Estimation (KDE) method has been applied to smooth the data. Identifying temperatures outside the operating range of IoT devices (−30 °C to +30 °C) highlights areas where the risk of device failure due to extreme weather is highest. This analysis highlights regional climate change and offers strategies to enhance the resilience of IoT devices in vulnerable areas, ensuring their reliable operation in future climate conditions.
To identify and visualize the regions in Kazakhstan where IoT devices are most at risk of failure due to extreme temperatures risk analysis has been implemented. The probability density approach provided an effective way to capture the likelihood of temperature extremes beyond device operating thresholds. To complement density plots, we added an alternative visualization in the form of a heatmap, which illustrates the spatial distribution of IoT device failure probabilities across Kazakhstan. This heatmap allows clustering of regions with similar risk levels, highlighting hotspots where resilience strategies should be prioritized (
Figure 4). To create the graph, we calculated the percentage at risk for IoT devices in different regions by analysing the temperature distributions using kernel density estimation (KDE). This involves integrating the probability density to determine the area outside the operating temperature range (−30 °C to +30 °C) and dividing by the total area to determine the percentage at risk. A graph is created for historical and future climate scenarios, providing a comparative overview of how the risks of IoT device failure change with climate change. This visualisation highlights high-risk regions and helps prioritise strategies to improve device resilience to extreme climate conditions.
To assess the vulnerability of IoT devices to extreme weather conditions, we have developed risk curves that visualise the probability of device failure based on temperature distribution.
Figure 5 displays four regions to provide a more detailed analysis of temperature distribution and IoT device risk, allowing for a deeper examination of each region’s different specific conditions. The process begins with the collection of temperature data for specific regions (e.g., North, South, East and West Kazakhstan) from reliable sources such as ERA5 or CMIP6 climate projections. These data include historical and future scenarios, allowing us to analyse both current and projected risks.
Using the kernel density estimation (KDE) method, we smoothed the temperature distributions to create continuous probability density functions (PDFs). These PDFs illustrate the probability of occurrence of different temperature ranges in each region. The operating limits of IoT devices, which are usually defined as −30 °C to +30 °C, are used as thresholds to define risk zones, i.e., areas where temperatures exceed these limits.
The next step is to calculate the percentage of PDF that falls outside of these operating limits. This is done by integrating the density function in the risk zones and normalising with respect to the total area under the curve. The result is expressed as a risk percentage indicating the probability of equipment failure due to temperature extremes in each region.
Finally, risk curves are plotted for each region, showing the probability density of temperatures along with the operating limits markers. This visualisation highlights the frequency and severity of extreme temperature events and allows for a clear comparative analysis between regions. These risk curves are essential for identifying high-risk areas and developing strategies to improve the resilience of IoT devices to changing climate conditions.
The qualitative data from interviews with IoT specialists, climate scientists, and professionals in sectors reliant on IoT devices, such as transportation, logistics, and agriculture, provided valuable insights into the operational challenges faced by IoT devices (
Figure 6).
As the core of this research involved developing risk estimate curves to quantify the probability of IoT device failure under different climate conditions, we analysed historical climate data and defined threshold values for temperature and humidity beyond which device performance is likely to degrade. These thresholds were derived from both literature and manufacturer specifications for IoT devices [
25] as mentioned in the previous section. Risk estimate curves were constructed by mapping device performance data against environmental variables, such as temperature and humidity. For instance, sensors typically perform optimally within a specified temperature range, but their performance declines or fails when exposed to extreme temperatures. The resulting curves demonstrate the likelihood of failure as climate variables deviate from these baseline operational ranges (
Figure 7).
The findings from this research provide an assessment of the climate risks IoT devices face in Kazakhstan (
Figure 6 and
Figure 7). Through a combination of quantitative climate data analysis, qualitative interview insights, and risk modelling, we have identified key challenges and vulnerabilities in IoT systems under current and future climate conditions. These insights will help guide policymakers, organisations, and IoT developers in creating targeted adaptation strategies to enhance the resilience of IoT devices in Kazakhstan’s climate. The use of risk estimate curves, integrated with climate projections, offers a valuable tool for forecasting future challenges and planning for climate-resilient IoT infrastructure. The visualizations produced in this study will be instrumental in identifying priority areas for investment in climate adaptation measures.
5. Adaptation Strategies and Resilience Planning for IoT Devices in Extreme Climates
5.1. Hardware Adaptation and Design Improvements for IoT Devices in Extreme Climates
To ensure reliable operation of IoT devices under Kazakhstan’s extreme climatic conditions—where winter temperatures can fall below −40 °C and summer heatwaves exceed +40 °C—specific hardware improvements and design adaptations are required. For extremely cold environments, devices should integrate low-temperature lithium-thionyl chloride (Li-SOCl2) batteries with stable voltage output down to −60 °C, as well as thermal insulation layers and self-heating circuits using resistive or phase-change materials to prevent battery degradation and sensor freezing. Printed circuit boards (PCBs) and connectors must use flexible polymer substrates resistant to thermal contraction, while enclosures should employ IP66-rated weatherproof housings with hydrophobic nano-coatings to block moisture ingress and ice accumulation.
During prolonged heatwaves, devices benefit from heat-dissipating aluminum or graphene-based casings, temperature-adaptive firmware, and solar-reflective coatings that reduce surface heating. Power management circuits should include automatic thermal shutdown mechanisms and energy-harvesting modules (e.g., photovoltaic or piezoelectric) to ensure continuous operation when grid power is unstable. In both extremes, adaptive calibration algorithms can maintain sensor accuracy, while redundant connectivity (e.g., dual-SIM or e-SIM with 5G fallback) can prevent data loss when communication modules are thermally stressed.
Future IoT designs for Kazakhstan and Central Asia should therefore adopt climate-resilient hardware standards, combining robust materials, smart energy systems, and predictive control software. These design features not only extend device lifespan but also align with Electronics journal requirements for engineering innovation in extreme environmental conditions, contributing to the global advancement of sustainable IoT technologies.
5.2. Economic and Uncertainty Considerations in IoT Climate Adaptation
A critical component of IoT climate resilience is the economic feasibility of adaptation measures. Although the physical and technical resilience strategies discussed in this paper—such as protective casings, redundant communication systems, and predictive maintenance—are effective in mitigating risks, their cost-effectiveness determines practical adoption. For instance, climate-resilient enclosures made of thermally stable polymers or graphene composites can be 20–40% more expensive than standard materials, while predictive maintenance systems require additional software integration and data management costs. However, these investments often result in reduced long-term maintenance and replacement expenses, especially in regions with frequent temperature extremes.
Based on stakeholder interviews, organizations in Kazakhstan’s energy and agricultural sectors reported that maintenance costs due to weather-related device failures can exceed 15–25% of total IoT operational budgets annually. By comparison, upgrading to climate-resilient designs or adopting redundancy strategies could reduce these losses by up to 30% over a five-year period. Therefore, while initial costs are higher, adaptive strategies provide a favorable return on investment through reduced downtime, longer device lifespan, and fewer system disruptions. Future work should include a detailed cost–benefit model integrating failure probability curves with economic loss estimates to support data-driven investment planning.
In addition, it is important to acknowledge the heterogeneity of IoT device specifications. The analysis in this study used general operating ranges representative of commonly used outdoor devices, including models such as Hikvision DS-2CD series cameras, Siemens IoT2040 gateways, and Bosch BME280 environmental sensors, all of which have comparable thermal and humidity tolerances. However, variations between manufacturers can introduce differences in operational reliability, and future research should incorporate model-specific testing to refine the risk estimates.
Finally, while ERA5 and CMIP6 datasets provide robust foundations for climate analysis, uncertainty remains inherent in global circulation models (GCMs). Variability among CMIP6 ensemble members (typically ±0.5 °C to ±1.2 °C temperature deviation for Central Asia by mid-century) and observational bias in reanalysis datasets can influence absolute risk values. To address this, future modelling will incorporate multi-model ensemble means and uncertainty bands to provide error margins in projected failure probabilities, ensuring more reliable decision-making support.
6. Conclusions
In conclusion, this study assessed the vulnerability of Internet of Things (IoT) devices in Kazakhstan to climate extremes by integrating ERA5 and CMIP6 climate projections with device operating thresholds and stakeholder interviews. The results demonstrate that IoT systems face increasing risks from temperature extremes, humidity fluctuations, and additional stressors such as solar radiation, windstorms, heavy snowfall, and droughts. Our findings show that northern Kazakhstan is most vulnerable to severe cold events, while southern and central regions face heightened risks from prolonged heatwaves. These climatic pressures significantly increase the probability of device malfunctions, particularly in sensors, cameras, routers, and POS systems. Interviews confirmed that stakeholders are concerned about maintenance difficulties, calibration errors under extreme conditions, and unreliable power supply in remote areas. Several resilience strategies emerged from this research. Technical measures include designing hardware with extended operating ranges, protective casings, and adaptive energy management. Operational measures involve predictive maintenance, redundancy in communication networks, and climate-informed deployment planning. Together, these approaches can enhance device performance and reduce operational downtime under extreme conditions. The integration of risk modelling, probability density functions, and spatial risk mapping provides policymakers and industry stakeholders with a practical framework to anticipate IoT failures and prioritize adaptation investments. By identifying regional “hotspots” of vulnerability, decision-makers can allocate resources more effectively to safeguard critical sectors such as agriculture, energy, and urban infrastructure. This study has three important implications: Policy and planning: National IoT strategies should include climate resilience standards, informed by risk projections. Research and development: Device design must incorporate tolerance to multiple stressors, including radiation, wind, and snow, not just temperature and humidity. In future studies, expanding validation with real-world device failure data and comparing resilience strategies across Central Asia will enhance model accuracy and regional relevance. In conclusion, IoT devices in Kazakhstan are highly vulnerable to projected climate extremes, but with targeted technical and operational adaptations, resilience can be significantly improved. The methodology developed here offers a transferable framework for other Central Asian countries facing similar challenges, contributing to the broader agenda of building climate-resilient digital infrastructures.
