Special Issue Information

Dear Colleagues,

In accordance with the Paris Agreement under UNFCCC, Nationally Determined Contributions (NDC) were announced, and carbon absorption from forest resources were included in NDC in many countries, including Republic of Korea (ROK). Securing a determined amount of carbon storage and absorption in forests can play an important role in ensuring NDC’s soundness. Forest biomass and carbon should be estimated through the analysis of forest activity data and the usage of a carbon accounting system. In addition, these two factors should be integrated into forest growth models that can predict future carbon stock under a forest management regime. A National Forest Inventory (NFI) system should be well operated to maintain a confidential national forest carbon database. Land cover/use change monitoring is also essential for monitoring the national carbon budget in relation to the LULUCF (Land Use, Land-Use Change, and Forestry) mechanism and the MRV (Measurement, Reporting, and Verification) system. Remote sensing has been utilized for national forest inventories and the MRV system for many decades, using mainly spaceborne, airborne, and recently unmanned aerial vehicle remote sensing.

In this Special Issue of Remote Sensing, we welcome original and innovative research papers focusing on forest monitoring, reporting, and verification associated with climate change mitigation and adaptation using earth observation data. We expect that this Special Issue will contribute to the improvement of monitoring, reporting, and the verification of forests using remote sensing technique, and to an enhancement in climate change responses by advancing our knowledge and understanding of mitigation and adaptation in the forest sector.

Topics can include but are not limited to the following:

Earth observation-based monitoring, reporting, and verification (MRV) of the forest environment;
The estimation of greenhouse gas (including carbon and nitrogen) using earth observation data;
Forest carbon stocks for a national greenhouse gas inventory;
Land Use, Land-Use Change and Forestry (LULUCF);
Climate change impact and vulnerability assessments of forests;
Adaptation to climate change in the forestry sector using spatial data;

Leaf pigment contents, such as chlorophylls a and b content (C

Leaf pigment contents, such as chlorophylls a and b content (C

) or carotenoid content (Car), and the leaf area index (LAI) are recognized indicators of plants’ and forests’ health status that can be estimated through hyperspectral imagery. Their measurement on a seasonal and yearly basis is critical to monitor plant response and adaptation to stress, such as droughts. While extensively done over dense canopies, estimation of these variables over tree-grass ecosystems with very low overstory LAI (mean site LAI < 1 m

), such as woodland savannas, is lacking. We investigated the use of look-up table (LUT)-based inversion of a radiative transfer model to retrieve LAI and leaf C

and Car from AVIRIS images at an 18 m spatial resolution at multiple dates over a broadleaved woodland savanna during the California drought. We compared the performances of different cost functions in the inversion step. We demonstrated the spatial consistency of our LAI, C

, and Car estimations using validation data from low and high canopy cover parts of the site, and their temporal consistency by qualitatively confronting their variations over two years with those that would be expected. We concluded that LUT-based inversions of medium-resolution hyperspectral images, achieved with a simple geometric representation of the canopy within a 3D radiative transfer model (RTM), are a valid means of monitoring woodland savannas and more generally sparse forests, although for maximum applicability, the inversion cost functions should be selected using validation data from multiple dates. Validation revealed that for monitoring use: The normalized difference vegetation index (NDVI) outperformed other indices for LAI estimations (root mean square error (RMSE) = 0.22 m
