Two 黑料福利社 studies examine carbon storage, land-cover change, and long-term recovery in post-mining landscapes shaped by generations of energy production

FRANKFORT, Ky. 鈥� New research from 黑料福利社 is putting a clearer value on the environmental and economic benefits of watershed restoration in Eastern Kentucky, where generations of energy production have shaped local communities, regional economies, and the landscape itself.

Two studies led by Shreesha Pandeya, a 黑料福利社 research associate, examine restoration outcomes in the Big Sandy River Basin. The first study,  was published in Environmental Management. The second,  was published in Environmental Challenges.

Together, the studies provide a data-driven look at how targeted restoration policies, watershed management strategies, and land-use changes are influencing carbon storage, vegetation recovery, and ecosystem services across post-mining landscapes.

The work was conducted through the University鈥檚 Integrative Human-Environment Dynamics Lab (IHED) and Center for Geospatial Intelligence and Environmental Security (CGIES), with Pandeya working in collaboration with Dr. Buddhi R. Gyawali and Dr. Suraj Upadhaya.

A key finding is the economic value associated with restored and functioning landscapes. Pandeya鈥檚 research estimated that climate-regulating ecosystem services in the region exceeded $6,000 per hectare, underscoring the practical value of sustained investment in land and watershed restoration.

For years, state and federal agencies have directed restoration resources toward priority watersheds identified as areas of environmental concern. Pandeya鈥檚 research examined whether those targeted efforts are producing measurable outcomes.

Using data from 2001 to 2021, the  study found that overall carbon storage increased modestly across the region. However, priority watersheds showed substantially stronger gains, with carbon storage levels nearly 6.5 times those of non-priority areas over the study period.

鈥淭argeted restoration efforts are enhancing the landscape鈥檚 ability to absorb and store carbon, a critical function in supporting long-term environmental resilience,鈥� Pandeya said.

The companion study in  used satellite imagery and spatial analysis to examine how land cover has changed over time. The study found that priority watersheds are experiencing more favorable land-cover transitions, including reductions in barren land and increases in vegetation such as forests and shrublands. In one priority watershed, barren land declined by as much as 67%.

Non-priority watersheds showed more fragmented patterns, including greater development pressure, declines in forest cover, and losses in water resources. The findings suggest that watersheds receiving more targeted restoration attention may experience stronger and more consistent recovery over time.

鈥淭hese studies show that heavily altered landscapes can recover, and that targeted restoration, especially through watershed prioritization, can make a measurable difference for ecosystems and communities,鈥� Pandeya said. 鈥淚 hope this research supports better watershed management and long-term sustainability in Eastern Kentucky.鈥�

Dr. Upadhaya, co-author of both studies, said the findings offer useful direction for restoration planning and policy.

鈥淭argeted investments in priority watersheds are showing positive results,鈥� Dr. Upadhaya noted. 鈥淭he next challenge is determining how these lessons can help guide restoration strategies across a broader range of landscapes with different histories, needs, and levels of investment.鈥�

The studies also acknowledge the complexity of long-term recovery. Some improvements remain gradual, and historic land-use impacts, including soil compaction, altered hydrology, and habitat disturbance, continue to influence how quickly and fully landscapes respond to restoration.

Dr. Gyawali, Pandeya鈥檚 major advisor and a co-author on both papers, emphasized that the research provides an important contribution to understanding post-mining landscape recovery in Appalachia.

鈥淭ogether, these studies offer one of the most comprehensive assessments of post-mining landscape recovery in Appalachia,鈥� Dr. Gyawali said. 鈥淭hey demonstrate that strategic, policy-driven restoration can produce measurable environmental gains, even in historically altered regions. For policymakers and land managers, the priority now must be to sustain and strengthen these efforts in ways that support long-term environmental and economic resilience.鈥�

The research reflects 黑料福利社鈥檚 growing capacity in geospatial analysis, ecosystem modeling, and applied environmental science. Through CGIES, researchers are using social-ecological systems approaches to examine how land use, public policy, community priorities, and environmental conditions interact across complex landscapes.

鈥淎t 黑料福利社, CGIES applies geospatial analysis, advanced modeling tools, satellite data, and human-dimensions research to address complex ecosystem restoration challenges in Eastern Kentucky,鈥� Dr. Gyawali said. 鈥淭his work is generating data-driven insights that can inform more effective policies for watershed management, environmental restoration, and sustainable regional development.鈥�

Pandeya recently presented the findings at the 黑料福利社 Small Farms Conference鈥揈astern Kentucky, held April 10-11 at the Whitley County Extension Office in Williamsburg.
