Soil carbon benefits

Course title: Soil carbon benefits
Course code: ISRIC-SOC
Subject areas (Curriculum): Soil use and management; environmental services
Duration: 3 hrs
Short description:

The human-induced increase in atmospheric greenhouse gas (GHG) concentrations poses a threat to the global environment and human well-being. Mitigating GHG emissions is a major challenge and needed to curtail climatic change. Some two thirds of all terrestrial organic carbon is contained in the soil; vegetation accounts for the rest. Soils are important long-term reservoirs of organic carbon; inorganic (carbonate) carbon can be important in semi-arid and arid regions. The amount of carbon in soil, present in soil organic matter (SOM), is strongly influenced by changes in land use and management. Sustainable land management (SLM) projects have the potential to not only reduce GHG emissions, by reducing emissions from biomass burning, biomass decomposition and the breakdown of soil organic matter (SOM), but also to sequester carbon (C) through practices that increase biomass production and promote the build-up of SOM.

This introductory lecture (~1.5 hr) provides an overview of important development and research issues for monitoring, reporting and verifying (MRV) soil carbon benefits in SLM and GHG mitigation projects followed by an overview of the online tools developed for the GEF by the Carbon Benefits Project (CBP). Subsequently, attendants may do a hands-on exercise (~1.5 hr), starting with the Simple Assessment Tool developed by the CBP

Moderators: Niels H. Batjes
Target audience: BSc and MSc level students in agriculture and other environmental sciences
Requirements: Basic knowledge of geography, soils and plant production; good understanding of English.
Programme:
  • B 1: Introductory lecture on important development and research issues for monitoring, reporting and verifying (MRV) soil carbon benefits in sustainable land management (SLM) and GHG mitigation projects; carbon offsets; aims and functionalities of CBP online system.
  • B 2: Hands-on-excercises starting with the Simple Assessment Tool of the GEF-CBP system, using activity data for a test case area and IPCC default data for climate and soils and emission factors (IPCC Tier 1 level approach).
     
Objective: After completion of this introductory course, participants should have a broad understanding of: 1) main factors regulating the global distribution of SOM, 2) options for enhancing SOM levels with improved management, 3) an insight in (new) approaches and techniques for measuring, monitoring and modelling SOC, 4) recognize the multiple benefits of soil organic carbon as held in SOM,  5) be familiar with the CBP modelling system, and 6) have some hands-on-experience with at least the Simple Assessment Tool.
Software / materials:

A room with PC's will be available for the hands-on excercise with the CBP tool.
Tutorials and datasets will be made available online to the course participants.

Case studies:

The case study considers an hypothetical project area in Kenya for which the necessary data are available. Subsequently, participants may explore project scenarios for an area of their choice (for which they must supply information about: intial land use, the baseline scenario and project scenario) using the Simple Assessment or explore the Detailed Assessment tool.

Adoption of recommended management practices can help restoring SOC stocks and reduce GHG emissions. These effects can be estimated using the online Carbon Benefit Project tools.
