WEST LAFAYETTE, Ind. — Purdue College’s Jingjing Liang has obtained a two-year, $870,000 grant from the World Assets Institute to map world forest carbon accumulation charges.
“To precisely seize the carbon accumulation charges of forested ecosystems the world over has all the time been a difficult job, principally as a result of doing so requires plenty of ground-sourced knowledge, and presently such knowledge are very restricted to the scientific group,” mentioned Liang, an affiliate professor of quantitative forest ecology and co-director of the Forest Advanced Computing and Artificial Intelligence Lab.
“This job is significantly more difficult than mapping carbon emissions from forest loss,” mentioned Nancy Harris, analysis director of the Land & Carbon Lab on the World Assets Institute, a nonprofit analysis group based mostly in Washington, D.C. “With emissions, there’s a transparent sign in satellite tv for pc imagery when bushes are minimize, resulting in a giant drop in forest carbon shares and a comparatively abrupt pulse of emissions to the ambiance. With sequestration, forests accumulate carbon progressively and nonlinearly.
“Even essentially the most superior satellite tv for pc sensor can’t seize this reliably by itself, particularly in older forests the place the sign saturates. A forest stops getting taller lengthy earlier than it stops accumulating carbon.”
Forest carbon accumulation charges are delicate to the delicate modifications in three forest progress parts: ingrowth, upgrowth and mortality. Ingrowth represents the variety of small seedlings which have attained a particular threshold measurement to be referred to as bushes. Upgrowth is the gradual improve in diameter of bushes by means of the method of photosynthesis. Floor-sourced forest stock knowledge measured at a number of deadlines is presently the one dependable supply of data for correct quantification of those three forest progress parts.
“To this point, folks have by no means been capable of estimate the ingrowth, upgrowth and mortality charges of particular person forest stands at a worldwide scale. This info hole leaves large uncertainty within the measurement, location and development of world forest carbon sink,” Liang mentioned.

Liang is growing a man-made intelligence mannequin that can mix info collected about billions of bushes measured on-site with satellite tv for pc and different geospatial knowledge to map native forest progress charges all through the worldwide forest vary.
“This would be the first AI-based forest progress mannequin deployed at a worldwide scale,” he mentioned. Past precisely quantifying carbon dynamics, Liang’s AI-based forest progress mannequin can even seize the dynamics of forest biodiversity and timber high quality.
“We’re excited to help the expansion of this analysis collaboration,” Harris mentioned. “The spatially granular knowledge this new venture will present will assist us higher perceive the position our planet’s forests play in native, nature-based options to mitigate world local weather change. The inclusive and globally networked strategy of this initiative is on the coronary heart of the mission of WRI’s Land & Carbon Lab.”
Creating such a mannequin requires large computing energy and complete world knowledge protection. The state-of-the-art high-performance computing clusters at Purdue will present adequate computing help. Nonetheless, reaching complete world protection of ground-sourced plot knowledge stays a problem, significantly in tropical international locations.
“The info from these international locations have been restricted traditionally,” Liang mentioned. “By means of the newly established community of Science-i and its sister consortium, the Global Forest Biodiversity Initiative, we have already got working relationships with a lot of scientists the world over who’re accumulating and sharing these knowledge.”
Liang based Science-i, a web-based collaboration platform involving greater than 300 scientists around the globe. He additionally co-founded the International Forest Biodiversity Initiative, which has constructed a database of 1.3 million pattern plots and 55 million bushes. That database will function the venture’s foundation.
“We’re going to acquire way more knowledge, particularly from the worldwide south, to fill these knowledge gaps,” Liang mentioned. “We’ll get extra folks concerned, particularly these from underrepresented teams.”
Collaborators of this venture already embody representatives of Indigenous teams throughout North America, Amazonia, Africa and elsewhere. Rural communities, forestry practitioners and citizen scientists can even turn into venture collaborators.
“We co-produce the data based mostly on the FAIR precept of world collaboration: findable, accessible, interoperable and reusable,” Liang mentioned.
“In Science-i, everybody collaborates with one another as equal companions on all tasks. We brazenly share our findings with clear real-time discussions throughout the entire staff. Then we cross-evaluate and consolidate our analysis findings on the finish. This can be a brand-new method to do worldwide collaborative forest analysis.”
The in depth world partnership and complete forest tree database created from this venture will complement Purdue’s Digital Forestry Initiative, which seeks to leverage expertise and multidisciplinary experience to measure, monitor and handle city and rural forests.
Liang is co-lead, with Ximena Bernal, affiliate professor of biological sciences, for the Biodiversity Research Community, a part of Purdue’s not too long ago launched multidisciplinary Institute for a Sustainable Future.
