Abstract
Forests are the primary contributors to carbon sequestration within the land use sector; however, several studies have demonstrated that also woody agroecosystems can play a non-negligible role in carbon sequestration, especially when sustainable management practices are adopted. Nonetheless, research in this sector is still limited and mainly focused on soil C sequestration only. In this context, it is necessary to implement methodologies that allow for the correct estimation of C sequestration across all the C pools, preferably using technologies ensuring the accuracy and traceability of C removals. To address this, the project “Dig-GHG, New Digital Technologies for full carbon accounting of forests and woody crops” aims to identify, and eventually to develop, the most suitable technologies for monitoring C sequestration in all carbon pools with high temporal resolution. The goal is to to provide an accounting tool for net C and GHG balance to support an MRV process for the generation of high-quality and verifiable carbon credits in forestry and agroforestry sectors. The project involves the assessment of carbon stored in the different C pools in two experimental sites: a mixed forest in northern Italy and an olive grove in central Italy. The two sites are equipped with a flux tower and a network of IoT sensors (TreeTalker-Cyber) measuring sap flow and radial growth in near-real time. In addition, for each of these sites, TLS has been used to estimate volume and AGB of trees and therefore to derive the carbon stored in their woody biomass, which will be used to calibrate site specific allometric equation and to derive AGB change using the radial growth measured with the TreeTalker as an input. To integrate below-ground biomass into the carbon budget, the project aims to develop a low-cost rhizotron for monitoring root growth. Furthermore, an innovative IoT technology called SoilTalker will be developed and tested to continuously measure CO2, CH4, and O2 concentrations in the soil, along with soil moisture and temperature, providing comprehensive data for the soil carbon pool.
