Agenda About the training Within the framework of SERVIR-HKH, Bangladesh Forest Department (BFD) and ICIMOD are jointly organising a training workshop on improving above-ground forest carbon estimation and degradation monitoring in Bangladesh. The training workshop is supported by SilvaCarbon, United States Agency for International Development (USAID) and National Aeronautics and Space Administration (NASA). The training will cover four components that support forest carbon emission monitoring efforts: terrestrial laser scanning (TLS), global ecosystem dynamics investigation (GEDI), SAR (Synthetic Aperture Radar), and continuous degradation detection (CODED) algorithm. Participants will learn necessary skills and knowledge on different methods leveraging open-source remote sensing data for improving above-ground forest carbon estimation of Bangladesh. They will be familiar with Online Biomass Inference using Waveforms And iNventory (OBIWAN), GEDI-incorporated model-based above-ground biomass (AGB) estimation, and tools to understand time series wall-to-wall biomass estimation. They will also learn TLS data for biomass estimation at the individual tree scale, which will help improve the capacity to scale biomass estimation from the plot to the regional level. Another method participants will be using is SAR, to improve carbon estimation and wall-to-wall mapping. Participants will also be introduced to CODED algorithms for tracing forest degradation. We developed this training content and delivery in collaboration with NASA SERVIR Applied Sciences Team (AST), and the Government of Nepal’s Forest Research and Training Centre (FRTC). Objectives Familiarise participants with different methods and data Share background and updates on the CODED algorithm, used by FRTC for forest degradation monitoring, and discuss further improvements for the application of CODED Seek feedback from participants regarding the different methods and their needs. This feedback will help refine the methods and models to meet the specific needs of stakeholders Bring together relevant stakeholders who are actively involved in forest carbon-related works and management. The training workshop will provide a platform for them to share their experiences, challenges, and emerging forest monitoring requirements. Expected outcomes Upon completion of the training, the participants will have a better understanding of the applications of annual forest cover status in Bangladesh and tools including RLCMS, TLS, GEDI, SAR, and CODED in monitoring forest condition and carbon stocks, enabling them to apply the knowledge in their working areas. At the end of the training, participants will outline a feasible method and data appropriate for the country. Expected participants We will organise the in-person training for 20 participants from national agencies in Bangladesh, including Bangladesh Forest Department (BFD), Bangladesh Space Research and Remote Sensing Organization (SPARSO), United States Forest Service, Community Partnerships to Strengthen Sustainable Development Program (USFS COMPASS), universities and other relevant organisations.

The first component, regional land cover monitoring system (RLCMS) generated an annual land cover maps of the HKH region, each year from 2000–2022. It is an operational system that updates land cover maps annually leveraging open Earth observation data using state-of-the-art methods. This provides an opportunity to prepare activity data. Secondly, SAR microwave imaging system with cloud penetrating and all-day data acquisition capabilities, provide viable alternatives to effectively measure and monitor forest biomass and forest carbon at national scales. Further, there are opportunities to integrate optical and SAR data, which help in improving forest biomass estimation. Next is TLS, which provides comprehensive data on forest structure, enabling more precise biomass estimation compared to traditional methods. Fourth is GEDI, a spaceborne LiDAR sampling instrument, collecting waveform return data for 25m footprints spaced at 60m intervals along parallel ground tracks that are approximately 600m apart. Transparent methods have been developed to use GEDI to infer mean biomass with clear estimates of uncertainty. These methods have been built into OBIWAN, an interactive public tool developed to address carbon estimation in individual jurisdictions. Lastly, the CODED algorithm relies upon time series analysis of the forest component of a spectral unmixing process applied to all available Landsat imagery. It is a leading algorithm for mapping forest degradation, which is canopy disturbance that does not result in deforestation. The amount of area affected by degradation, and its carbon consequences, are often greater than those of forest conversion.
