Current approaches to interventions that reduce the transmission of vector-borne diseases under changing climate 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.

Achieving transparent and equitable allocation mechanisms for scarce climate finance at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Despite recognition of its importance, reliable methods for solutions for managing the growing volumes of construction and demolition waste 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.
