• December 11, 2025: A paper, titled "Understanding the efficacy and efficiency of Thermal Infrared UAV for Wildlife Monitoring", has been accepted for publication at Environmental Monitoring and Assessment. According to this paper, thermal infrared imaging from uncrewed aerial vehicles (UAVs) offers a promising tool for monitoring wildlife populations and habitat use. Comparing programmed flight routines and manual UAV surveys in Nepal’s Chitwan National Park, we found that manual flights required less survey and processing time while detecting similar numbers of large mammals as programmed flights. Although both methods were subject to observer bias, only manual flights provided imagery sufficient for reliable species-level identification, highlighting trade-offs between efficiency and taxonomic detail in UAV-based wildlife monitoring. Led by Dr. Eve Bohnett (lead author) under An and his team's CNH2 project, this paper marks an important step towards applying geospatial technologies to wildlife monitoring and assessment.

• August 15, 2025: Ren Cao and Dr. Li An have published a paper titled “Effects of concurrent conservation initiatives on forest-adjacent communities in the Chitwan Valley, Nepal” in Forest Policy and Economics. The study uses household survey data from 2014 and 2017 to examine how Community Forestry (CF) and Scientific Forest Management (SFM)—which involves silvicultural management of forests—jointly affect travel distances for firewood and fodder collection among forest-adjacent households in the Chitwan Valley. Through temporal comparisons, t-tests, chi-square tests, and interaction modeling, the paper analyzes changes in and determinants of travel distances over time. Results show that the co-existence of CF and SFM can generate both positive and negative effects on the efforts to access forest resources, especially when households face trade-offs in meeting daily subsistence needs. The study also highlights how these effects vary across social groups, such as caste, pointing to the importance of recognizing pre-existing social inequalities when designing and evaluating layered conservation efforts. The findings contribute to policy dialogues on how silvicultural interventions and other conservation programs shape rural livelihoods in biodiversity-rich landscapes.

• August 25, 2024: Between August 3rd and 19th, Ph.D. student Ren went to the Chitwan Valley to investigate how community forests were involved in and benefited from a nationwide silvicultural program called the Scientific Forest Management (SciFM). Ren’s travel aimed tod understand the potential interactions between SciFM and other existing conservation initiatives. He visited eight community forest (CF) offices in the Eastern Chitwan Valley and visited the restricted areas of forest stands currently under CF management. Upon receiving a modified IRB protocol from Auburn University, he will work with the Nepali research partner, the Institute for Social and Environmental Research – Nepal (ISER-N), to conduct eight interviews with community forest officers in the Eastern Chitwan Valley about their participation in—and attitudes towards—the SciFM program. In 2023, our research team conducted a social survey in these eight community forests. The new forest management interview data will be helpful for comparing household livelihood decisions, child education, and migration choices under different forest management practices. The goal is to examine how concurrently implemented conservation programs can influence household livelihood decisions.

• January 01, 2024: A paper led by Dr. Li An, titled "Global hidden spillover effects among concurrent green initiatives", has been accepted for publication in Science of the Total Environment (impact factor 9.8).

How to assess spillover interactions, when our featured policy intervention is not the only game in town? Which usually it isn’t… Using the US and China as examples, and zooming in on particular regions and green policies, the authors convincingly show that some programmes implemented in parallel are exhibiting synergies, yet others tradeoffs: careful empirical analysis is needed to assess which policy mixes have desirable effects. This book shows how we can get started!"
