Research efforts, on soil carbon management in agricultural lands, over the last two decades have sought to improve our understanding in order to increase soil productivity, soil carbon sequestration and to offset greenhouse gas emissions. This systematic review aims to identify the research gaps and future direction of soil carbon management in Australia. We explored and synthesized the use of social-ecological systems (SES) both in the global and Australian context, before making the first attempt to develop a conceptual SES framework for soil carbon management. Both quantitative and qualitative assessment of articles were used to identify and synthesise research trends, challenges and opportunities for improved soil carbon management. The results provide valuable insight into the SES components examined, the research gaps and the methodological challenges for research into soil carbon management conducted over the last two decades. The review revealed that research has predominately focused on the ecological component of soil carbon management in agricultural practices and has been conducted from a scientist's perspective. The sustainability of carbon-building soil management practices will require integration of social components into future research, particularly from a farmer perspective. The proposed conceptual SES framework is designed to identify and investigate SES components in soil carbon management in order to increase the process of offsetting greenhouse gas emissions as required by Sustainable Development Goals 2, 13 and 15. |
