We work on a variety of questions related to the role of vegetation in the terrestrial carbon cycle. Our primary tool for this work is the LPJ-GUESS dynamic global vegetation model. LPJ-GUESS has a particularly advanced representation of forest demography, facilitating our work on the following topics:
- The role of tree mortality in forest carbon turnover rates and implications for the future carbon cycle (see, e.g. Kautz et al., 2018, Schelhaas et al., 2018, Pugh et al., 2019).
- How natural and anthropogenic processes have shaped forest structure, and the role that this structure plays in the current carbon sink (see, e.g. Pugh et al., 2019, Pugh et al., 2020). This is the focus of a new Marie-Sklodowska Curie project on forest management (ForMMI) led by Susanne Suvanto.
- The effect of lags in ecosystem processes on carbon budgets consistent with limiting climate change (see, e.g. Pugh et al., 2018).
LPJ-GUESS also has an advanced representation of anthropogenic land-uses such as croplands, pastures and managed forests, which supports work on:
- The coupled interactions between the terrestrial biosphere, climate and human land-use change (see e.g. Alexander et al., 2018, Rabin et al., 2020).
- How changing a environment and anthropogenic pressures affect ecosystem service provision by the biosphere (see e.g. Krause et al., 2017).
- Crop modelling.
We also take an active role in model inter-comparison exercises and work closely with colleagues at the large Free Air CO2 Enrichment (FACE) experiment at the Birmingham Institute of Forest Research (BIFoR), for which we are able to offer modelling support.
