The number of peer-reviewed research publications on forest carbon has exploded in recent decades. From the signings of the Kyoto Protocol in 1997 to the Paris Agreement in 2015, much of the science and research conducted has been in response to the global challenges and opportunities that forests provide by sequestering and storing carbon.

Forest carbon has also been increasingly studied in forest management and silvicultural practices. New technologies and remote sensing have also brought about new ways to inventory forests for the biomass and carbon they store.

The number of peer-reviewed studies dealing with forest carbon is overwhelming, to the point that no one in their right mind would have the capacity to read every paper. This post describes how text mining can be used to investigate trends in forest carbon research over the last 20 years.

Peer-reviewed publications in forest carbon

To compile a data set, Web of Science was queried for all peer-reviewed papers containing the term “forest carbon”. Specifically, a paper was included in the data set if the term “forest carbon” was included in its abstract, title, or keyword field.

In total there were 2,668 papers obtained between 1985 and 2020. The number of forest carbon papers published since 2001 represent 97% of the data, or 2,582 papers:

The journals Forest Ecology and Management, Forests, and Global Change Biology are the three that have published the most forest carbon paper since 2001:

Conclusion

Research on forest carbon has leaped forward in recent decades. There are 2,582 peer-reviewed papers that have been published on forest carbon topics in the last 20 years. In recent years, more terms relating to technology and remote sensing have been incorporated into titles of forest carbon papers.

Thanks to Samuel Neal and Cindy Zheng for the inspiration for this post based on their excellent article looking at keywords in COVID-19 papers published in last month’s issue of Significance.
