• Assessing the impacts of agricultural managements on soil carbon stocks, nitrogen loss, and crop production - a modelling study in eastern Africa.

  Authors:Jianyong Ma, Sam S. Rabin, Peter Anthoni, Anita D. Bayer, Sylvia S. Nyawira, Stefan Olin, et al.From:Biogeosciences (Vol. 19, Issue 8) Peer-Reviewed

  Apr. 22, 2022322 words Brief article Improved agricultural management plays a vital role in protecting soils from degradation in eastern Africa. Changing practices such as reducing tillage, fertilizer use, or cover crops are expected to enhance soil organic...

• Modeling symbiotic biological nitrogen fixation in grain legumes globally with LPJ-GUESS (v4.0, r10285).

  Authors:Jianyong Ma, Stefan Olin, Peter Anthoni, Sam S. Rabin, Anita D. Bayer, Sylvia S. Nyawira, et al.From:Geoscientific Model Development (Vol. 15, Issue 2) Peer-Reviewed

  Jan. 28, 2022291 words Brief article Biological nitrogen fixation (BNF) from grain legumes is of significant importance in global agricultural ecosystems. Crops with BNF capability are expected to support the need to increase food production while reducing...

• Soil carbon response to land-use change: evaluation of a global vegetation model using observational meta-analyses

  Authors:Sylvia S. Nyawira, Julia E. M. S. Nabel, Axel Don, Victor Brovkin, and Julia PongratzFrom:Biogeosciences (Vol. 13, Issue 19) Peer-Reviewed

  Oct. 13, 2016286 words Brief article Global model estimates of soil carbon changes from past land-use changes remain uncertain. We develop an approach for evaluating dynamic global vegetation models (DGVMs) against existing observational meta-analyses of...
