How EUSPA Space Technology Helps Sustainable Forest Management

From promoting reforestation to preventing deforestation, degradation and fires, the EU Space Programme is an essential tool for sustainable forest management. Here's six ways that Copernicus, EGNOS and Galileo are all working to ensure that everyone can benefit from healthy forests.

1. Keeping an eye on carbon sinks

Trees are important carbon sinks, meaning they absorb more carbon from the atmosphere than they release. According to the Forest Information System for Europe (FISE), as of 2020, 's forests were storing 92.1 gigatonnes of carbon. Unfortunately, when forests disappear or become degraded, all this stored carbon gets emitted back into the atmosphere. 

This highlights the critical need to monitor the carbon stocks of forested regions – monitoring that can be done via Earth Observation. For example, using the Copernicus Land Monitoring Service, climate scientists can map and monitor forest biomass and estimate its potential to serve as a carbon sink. 

2. Planting 3 billion trees

A key component of the EU Forest Strategy, which aims to improve the quantity and quality of Europe's forests while also strengthening their protection, restoration and resilience, is to plant 3 billion new trees by 2030. According to the 2022 EUSPA EO and GNSS Market Report, will play a big part in achieving this goal. 

With the climate and weather data provided by Copernicus, authorities can better understand how different tree species will adapt to droughts, heatwaves and other climate-induced extreme weather events. EO can also provide decision makers with the data on soil composition they need to ensure these new trees are planted in the right conditions. 

3. Stopping deforestation 

When it comes to detecting, mapping and monitoring this deforestation, nothing beats Earth Observation. For example, EO-based tools for forest monitoring are using Copernicus data, along with the optical and instruments onboard Sentinel , to provide global information with a high acquisition frequency to forestry stakeholders completely free of charge.

The UN estimates that every year the world loses nearly 4.7 million hectares of forested area. Much of this loss is due to deforestation, the process of converting forested land into other uses. 

4. Preventing illegal logging

Copernicus can even help prevent illegal logging – a major cause of deforestation. By flagging potential development and road construction happening within forests, EO data helps authorities look for illegal activity and predict where such activity is most likely to occur. 

Authorities also use GNSS to track timbre movements, which can help increase the transparency and traceability of the timber , reducing the likelihood that illegal exportation goes unnoticed. 

5. Sustainable forests management 

Much of Europe's forests are under the management of the forest industry and are used to source raw material to produce paper and wood products. If these forests aren't sustainably managed, we could run out of raw material – which is why the forestry industry is keen on using Space. 

Forest managers and owners use technologies to gather data over the large, often remote swaths of land that managed forests cover. They then use this data to track relevant inventory and, based on this, optimise harvesting and planting plans. 

The forestry industry also relies on for such precision operations as the guidance of machinery and the variable rate application of fertilisers and irrigation – all of which allow the timber industry to implement best practices in sustainable forest management. 

Thanks to its more robust signals, Galileo performs better under dense tree canopies, enabling machine guidance in forest environments. Moreover, Galileo is used to guide drones, which are increasingly being utilised in forest management operations.

6. Fighting forests fires

With causing extreme draughts, heatwaves and winds, forest fires are becoming an all-too frequent occurrence. Luckily, fire departments and decision makers can rely on Earth Observation to help mitigate the risk of fires before they happen and to battle them when they do. That's because EO has the advantage of being able to provide wide geographic coverage and the ability to ‘see' through clouds and smoke and rapidly capture images. 

Firefighting teams are also replacing their ground-based systems and use of rotorcraft with drones equipped with a range of for capturing data. Such systems are particularly beneficial in rural and remote areas, where EO-equipped drones guided by the precise positioning offered by GNSS can provide wildfire fighters with another layer of information – and protection.
