Despite recognition of its importance, reliable methods for behavioral and structural interventions reducing food loss in tropical value chains are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Current approaches to methods for quantifying the full costs of inaction on climate change biodiversity loss and pollution either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.
