Forest Carbon Stock Estimation Using Airborne LiDAR

Climate change indeed poses a significant and widespread threat to Earth and its ecosystems. It is driven primarily by the increase in greenhouse gas concentrations in the atmosphere, primarily carbon dioxide (CO2) from human activities such as burning fossil fuels, deforestation, and industrial processes. Climate change also poses a significant threat to forests. Protecting and sustainably managing forests is critical for their ability to continue providing these climate-related benefits. Forests are vital for addressing climate change and its impacts.

Climate change and the need for forests are closely intertwined. Forests act as carbon sinks, absorbing and storing carbon dioxide (CO2) from the atmosphere through the process of photosynthesis. Trees and plants take in CO2 and release oxygen (O2), helping to reduce the concentration of greenhouse gases in the atmosphere. This is vital for mitigating global warming and reducing the impacts of climate change. Biomass estimation and mapping is a key elements of global climate change impact assessment, carbon stock quantification, site suitability for bioprocessing plants, investigating the terrestrial ecosystem’s carbon cycle, and assessing fuel energy for forest fires.

India in the 26th session of the United Nations Framework Convention on Climate Change (COP 26) in November 2021, announced its target to achieve net zero by 2070. India’s low-carbon development strategy document has elaborated the international and national context as relevant; the current policies and programs already being implemented as well as the key elements for each transition, potential benefits, and challenges.

GarudaUAV is a Trentar company under its visionary leadership has an efficient team with an innovative vision that has successfully carried out Forest Carbon Asset Mapping with “Make in India” in-house technologies. LiDAR and Hyperspectral equipped MAV along with a rapidly developing AI/ML can monitor and inspect large areas with focused coverage that yields faster and more precise data resulting in outputs required by the forest managers for rapid planning.

The forest carbon asset mapping survey is done using UAV/MAV-based LiDAR. In addition to the airborne survey, the team conducts a ground survey to calculate the DBH (Diameter Breast Height) of individual trees. By the application of in-house and other acknowledged multiple software along with the proper application of carbon stock estimation formula (which differ from region to region, size to size of tree’s trunk and features). The data processed are briefly provided below. All outputs are then uploaded and integrated into GarudaUAV’s in-house enterprise cloud platform BlueHawk.

The output will be generated from the Flora Carbon stock estimation process.
