Peatland Restauration Research

Researchers in Finland are studying how peatland restoration affects water balance, greenhouse gas emissions, and vegetation. The goal is to raise water levels, restore the natural peatland environment, and enhance carbon storage.

Sensor-Based Measurements and Hydrological Modeling
The University of Oulu is investigating how restoration impacts the water cycle, particularly where water flows when drainage ditches are blocked. It is expected that surface water distribution will become more even, the groundwater level will rise, and greenhouse gas emissions will decrease.
To analyze these effects, wireless sensors are used, including the Decentlab sensor DL-PR26 and DL-ZN1, which enables precise measurements. Additionally, ground-penetrating radar is used to examine peat layer thickness and permeable soil structures. These data feed into hydrological models that predict the long-term effects of restoration on the water system for up to 50 years.

Monitoring Greenhouse Gases and Microbial Processes
The Finnish Meteorological Institute and the Natural Resources Institute Finland measure greenhouse gas fluxes before and after restoration to assess its immediate impact. While water conditions change quickly, vegetation adapts more slowly. Microbial activity is analyzed using advanced sequencing methods to better understand carbon and nitrogen cycle processes.
Simulations are used to create long-term projections, including peat accumulation rates and peatlands' responses to climate change. The research is part of the LIFE PeatCarbon project, funded by the EU and conducted in collaboration with international partners.

Research: Trees under heat stress

Our forests are increasingly vulnerable to climate change. Rising temperatures and drought are affecting many tree species. Which ones are resilient enough to survive?

Our customer and partner, WSL, is exploring this in a model ecosystem MODOEK, where young European beech and downy oak trees are grown under controlled conditions – some with less water, others with temperatures 5°C higher, and some with both. After eight years, clear differences have emerged:

Key findings from the study:
• European beeches struggle with heat and drought, showing signs of stress and stunted growth.
• Downy oaks cope better with extreme conditions, using water more efficiently and adjusting leaf numbers.
• Water scarcity is a greater threat than heat. Beech trees suffer more from drought, while oaks manage better.
• Resource competition is crucial. Oaks outperform beeches in mixed stands.
• Trees can adapt – but only with time. Some species can adjust their photosynthesis temperature, but rapid climate shifts may put them at risk.

Sensors and long-term measurements are key to understanding how trees adapt to climate change.

Decentlab sensors can help collect detailed environmental data to track the trees responses. These findings guide scientists and foresters in preparing forest ecosystems for the future.

Which species will shape our forests future? Early results suggest that drought-resistant species like downy oak may play a major role. But research continues as our forests evolve.

Monitoring Technologies for Rockslide Detection

The newspaper NZZ recently reported on monitoring rockslides in Switzerland, highlighting how modern technologies can detect and mitigate dangerous rock movements. The companies Geopraevent, Terradata, and InNet mentioned in the article, utilize innovative radar, laser, and seismic technologies. Among many systems they make as well use of sensor devices for LoRaWAN  from Decentlab in some of their monitoring solutions.

A project by InNet vividly shows how quickly long-term monitoring can turn into an emergency. In Muotatal, Switzerland, InNet used laser distance sensors to monitor an unstable rock formation. The laser devices used were no larger than a coffee cup and were powered by batteries. Initially planned as a one-year test, the project revealed alarming acceleration of movements within days. In early summer of 2023, a helicopter transported the equipment to the site, where a mast was installed and sensors attached. These sensors, which provide accurate data every ten minutes, offered a compact and cost-effective solution that suited the project’s limited budget.

Wihtin a week of starting measurements, InNet issued a warning of an imminent rockfall. A few weeks later, the rock mass collapsed, covering an alpine pasture and a hiking trail—fortunately without causing any injuries.

This example highlights the critical importance of environmental monitoring sensors. Climate change is exacerbating the situation by increasing the frequency of extreme weather events and accelerating the melting of permafrost, which destabilizes slopes. Technologies like these not only help protect lives but also transportation routes and critical infrastructure.

Air Quality: Monitoring Gaps Threaten Millions

According to an article from Meteorological Technology International – new research reveals that monitoring gaps could leave millions of Americans, particularly in disadvantaged communities, exposed to dangerous levels of pollution without their knowledge.

The recent tightening of air quality standards by the US Environmental Protection Agency (EPA), reducing the fine particulate matter (PM2.5) annual health-based standard from 12 µg/m³ to 9 µg/m³, aims to prevent thousands of deaths and workdays lost by 2032. These microscopic particles, smaller than 2.5 µm, can penetrate deep into the lungs, causing serious health issues such as heart and respiratory diseases. The new standards could bring health benefits worth up to $46 billion.

Monitoring Gaps and Social Inequality:

A study by the University of California, Berkeley, however, reveals that the current monitoring network of about 1,000 stations has significant gaps. Around 44% of highly populated metropolitan areas—affecting about 20 million people—lack adequate monitoring. Particularly in disadvantaged communities, often located in heavily polluted regions, there are few monitoring stations.

Solutions:

The study suggests strategically adding more monitoring stations. Just 10 new stations in key locations could reduce the impacted population by 67%. In addition to traditional methods, mobile monitoring, satellite data, and low-cost sensors could help fill these gaps.

Future Challenges:

With the upcoming implementation of stricter standards (e.g., WHO guidelines at 5 µg/m³), these gaps could widen further. Expanding and modernizing the monitoring network is therefore urgently needed to effectively enforce these new policies and better protect vulnerable communities.

What will Climate feel like in 60 Years?

Imagine a future where Berlin's climate mirrors that of present-day Italy – this is what an interactive map created by scientists at the University of Maryland predicts. The map visualizes how temperatures and humidity levels across more than 40,500 cities worldwide could shift by 2080.

The simulation reveals a striking shift: cities in northern Europe will increasingly resemble the warm, Mediterranean climate. In a high-emission scenario, where global temperatures rise by up to 9°C, cities like Berlin would experience conditions similar to Italy's Emilia Romagna, while Milan could face an environment akin to present-day Saudi Arabia. By 2080, cities in the northern hemisphere will bear more resemblance to southern regions, while tropical areas such as Central America and North Africa will face unprecedented climate conditions without direct parallels in today’s world.

This interactive tool could be invaluable for scientists and urban planners, offering a powerful visualization that helps prepare for the infrastructure and health challenges that lie ahead in a changing world.

2024: Increased Moisture – Insights from Decentlab Sensors

As we reflect on the year, we'd like to share an interesting fact revealed by our DL-SMTP sensors in Switzerland: this year, the measurements showed a significant increase in moisture compared to the dry four years of the past. Particularly at locations like the one shown in our demo, where sensors were deployed across Switzerland, there were no prolonged dry spells during the summer, which was a welcome change compared to previous years.

Unlike the extremely dry summers of recent years, 2024 was notably wetter and thus more beneficial for nature. This is confirmed by preliminary soil water status data from TreeNet. This year marked a period with significantly fewer drought phases in Switzerland, providing a solid foundation for ecological balance.

Stay tuned for further updates and take advantage of our public demo dashboardsto track moisture levels in real-time at various locations across Switzerland.

Devastating Floods in Spain: Climate Change and the Need for Early Warnings Systems

The recent heavy rainfall and flash floods in Spain caused severe damage, resulting in numerous fatalities and significant economic losses. 

These catastrophic floods were caused by a combination of weather events and climate change. A key factor was the Isolated Depression at High Levels (DANA), which occurs when cold air from the polar regions collides with warm Mediterranean air, triggering intense rainfall and flash floods. Rising sea temperatures and increased atmospheric moisture mean the atmosphere can hold more water, significantly raising the likelihood of extreme precipitation. In some areas, 491 liters of rain per square meter fell within just eight hours, which is equivalent to an entire year's rainfall.

The World Meteorological Organization (WMO) highlights how climate change accelerates the hydrological cycle, making weather events more unpredictable and extreme. Studies show that rainfall in affected regions was approximately 12% more intense and twice as likely compared to the pre-industrial period. Given these changes, the WMO stresses the need for enhanced global early warning systems to better prepare for and mitigate such disasters.

The Early Warnings for All initiative, which seeks to ensure universal access to early warning systems, plays a crucial role in minimizing losses and damage. Accurate measurements of key environmental factors are essential. Sensors like Decentlab's DL-MBX, which provide real-time data for flood monitoring, form the foundation for the development and implementation of robust early warning systems.

What Is Particulate Matter?

The American Lung Association has published an insightful article about particulate matter (PM) that explains the topic well. Particulate matter consists of tiny particles such as dust, dirt, soot, smoke, and liquid droplets. While some particles are visible, many require a microscope to be seen. PM is categorized by size: larger particles are called PM10, while finer particles are known as PM2.5, which pose the greatest health risks.

Sources of Particulate Matter
Particulate matter comes from various sources, including:

• Cooking: Frying, grilling, or using gas stoves.

• Combustion Activities: Smoking, burning candles, and using fireplaces.

• Household Products: Cleaning agents, air fresheners, and aerosol sprays.

• Hobbies: Woodworking, metalworking, and crafting.

• Biological Sources: Mold spores, dust mites, and cockroaches.

• Outdoor Air: Vehicle emissions, wildfires, and industrial activities. Particle pollution can enter buildings through windows and ventilation systems.

Health Impacts of Particulate Matter
Inhalation of PM2.5 can penetrate deep into the lungs, causing irritation and exacerbating conditions like asthma and COPD, as well as leading to pneumonia, heart disease, stroke, and lung cancer.

Sensors like Decentlab's DL-PM | Particulate Matter, Temperature, Humidity and Barometric Pressure Sensor for LoRaWAN® and DL-IAM | Indoor Ambiance Monitor including CO₂, TVOC and Motion Sensor for LoRaWAN® help keep air quality in check, ensuring safer air for all.

Groundwater: Alarming Trends and the Need for Monitoring

In many parts of the world, alarming trends in groundwater are being observed as water levels dramatically decline in numerous regions. An analysis by CORRECTIV highlights concerning data for Germany: over a span of 32 years, groundwater levels have generally decreased more than they have increased.

The primary causes of this decline are human activities, particularly water extraction by industries, agriculture, and mining, which lead to water scarcity and conflicts over water resources. The lack of transparency regarding groundwater levels is exacerbated by the absence of standardized data collection. Additionally, the climate crisis intensifies the situation by hindering groundwater replenishment and increasing water demand.

To better understand this critical situation, CORRECTIV has developed an interactive map that provides an overview of groundwater level trends in Germany, based on data from approximately 6,700 measuring points. This map illustrates the alarming trends of recent decades.

Moreover, it is once again evident how essential data collection and long-term measurements are. Environmental sensors like the DL-PR26 and DL-PR36 facilitate continuous monitoring, providing valuable real-time data to swiftly respond to changes in groundwater levels.

Experiment investigates Air and Soil Dryness in Forests

The remarkable installation in the Pfynwald forest in Valais, Switzerland, is part of the globally unique “VPDrought” experiment, designed to unravel the effects of soil and air droughts in a natural forest ecosystem. This study explores how both air and soil dryness impact mature forest pines. The 130-year-old trees receive varying amounts of soil water, and high-pressure nozzles in some of the canopies spray water vapor during the day to reduce the vapor pressure deficit (VPD) by about 20 to 30 percent.

Our client and partner, WSL (Swiss Federal Research Institute for Forest, Snow and Landscape) and EPFL, are examining how these conditions affect tree resilience and dieback processes. The experiment will evaluate the effects of soil and air drought on plant physiology and ecosystem health. It will offer valuable information for developing future climate models and forest management strategies.
