The Small-Holder Agriculture Mitigation Benefit Assessment (SHAMBA) tool provides a simple, robust and easy to use method for estimating greenhouse gas (GHG) emissions or removals resulting from a change in land management practices.
SHAMBA was developed for the purpose of accounting for changes in soil and woody biomass carbon stocks and GHG emissions due to changing agricultural practices and tree planting and places land use GHG analyses at the fingertips of smallholder farmers, with less need for technical specialists.
Soil carbon and woody biomass changes are modelled with simple quasi-process-based approaches, whilst emissions from other sources (e.g. biomass burning, the use of fertilisers) are accounted for using simpler (IPCC Tier 1-type) approaches. The model consists of three sub-models, for soil, crops and woody biomass, working on a per hectare basis.
Tackling key GHG accounting issues
A key issue with current GHG accounting approaches is that their complexity makes the costly and inaccessible to non-specialists, including smallholder farmers. SHAMBA addresses this issue through being pre-parametrised and through a basic user interface.
Using the SHAMBA tool
To run the tool, users only need simple easily collected activity data – the type of data that is normally collected in the course of agroforestry or conservation agriculture projects.
SHAMBA contains databases of emission factors, tree allometry, climate and soil information, which means that the user does not need access to the scientific literature to generate state of the art estimates.
SHAMBA is designed to model a baseline scenario (where land management activities continue as business as usual) and an intervention scenario consisting of activities that can be described as Climate Smart Agricultural practices, including: conservation agriculture; agroforestry; and other tree planting.
Version one of the SHAMBA model is designed to work with smallholder systems in sub-Saharan Africa.
