MIT researchers examined the role geography has played in the opioid crisis. They find state-level policies inadvertently contributed to the rise of opioid addiction, and that addiction itself is a central driver of the long-term problem.

The Agricultural non-CO₂ Greenhouse gAs InveNtory (AGAIN) is a bottom-up model following the Tier 2 methodology of the IPCC to estimate emission trajectories and evaluate the mitigation potential of China’s agricultural non-CO₂ greenhouse gas (GHG) emissions at the provincial level through 2060 under four scenarios: business-as-usual (BAU), current policy (CP), conventional technical potential (CTP), and maximum technical potential (MTP). The model covers six agricultural subsectors, including freshwater aquaculture, and incorporates eight policy objectives and seventeen agricultural mitigation technologies within its scenario module. It can identify priority mitigation regions and sectors under different scenarios.
