Identifying opportunities for nature-based solutions with geospatialized life cycle assessments and fine-scale socioecological data

Environmental Research Letters
As we increasingly understand the impact that land management intensification has on local and global climate, the call for nature-based solutions (NbS) in agroecosystems has expanded. Moreover, the pressing need to determine when and where NbS should be

Carbon‐Intensive Agriculture: Agricultural Trade Openness, Energy Use, and Environmental Challenges in High‐Emission Countries

Sustainable Development, EarlyView.
ABSTRACT This study examines the socioeconomic determinants of agricultural CO2 emissions in the 10 highest‐emitting agricultural economies from 1992 to 2022. Using the LM bootstrap cointegration method and the method of moments quantile regression (MMQR), the analysis identifies long‐run relationships and heterogeneous effects across the emissions ...
