Estimating Carbon Stocks in Forest Ecosystems: From Allometric Equations to Remote Sensing-Based Methods

Dear Colleagues,

The determination of carbon stocks in forest ecosystems is a relevant input of global relevance. Many countries have signed the United Nations Framework Convention on Climate Change (UNFCCC) agreement, where initiatives related to reducing emissions from deforestation and forest degradation (REDD+) have been implemented. Considering such factors, rigorous methodologies regarding the quantification of carbon stocks are of paramount importance. Traditional approaches using allometric equations have been used for a long time in forest sciences. However, the accurate definition of allometric equations requires a destructive approach, which is also expensive, time-consuming, and in some cases inappropriate, considering that some species are protected by international organizations (e.g., CITES, IUCN).

Novel technologies that have become established and new ones that are being tested and validated can validly support, complement and in some cases substitute traditional methods. Remote sensing techniques and geomatics techniques in general i.e., measuring Earth data from satellite image analysis, photogrammetry, laser scanning etc.…, can be integrated by local and general allometric equations. However, even if the technologies are quite advanced, field data collection is always required, for training and/or validation.

The focus of this Special Issue is on documenting developing methodologies using existing site- and species-specific allometric equations to estimate carbon stocks and explore advanced and novel remote sensing technologies that allow measuring these data. Since allometric equations are specific to a species and to an environmental site’s condition, it will be relevant to include local equations as ground truth values. On the other hand, developing local and general allometric equations through photogrammetry, laser scanning and mobile applications can be a valid solution to the lack of allometric equations in the case of protected species which cannot undergo destructive analyses.

Suitable research papers for this Special Issue can be related to the following topics:

  • Active and passive earth-observation sensors;
  • Error propagation;
  • Photogrammetry;
  • Close-range sensing;
  • Airborne and terrestrial laser scanning;
  • SLAM-based hand-carried mobile laser scanning;
  • Forest inventory;
  • Forest biometry and modeling;
  • 3D modeling and augmented reality from remote sensing data;
  • Uncertainty metrics

Deadline for abstract submissions: 31 December 2021.
Deadline for manuscript submissions: 31 May 2022.
