Promoting innovations in climate change requires innovation partnerships and linkages and also creating an enabling environment for actors. The paper reviewed available information on the identification and mapping of linkages between actors in the climate change innovation system. The findings showed different linkage types and mechanisms that could exist
in the climate change innovation system. Actor linkage map, actor linkage matrix, actor determinant diagram and actor time lines were identified as ways of mapping linkages between actors in the climate change innovation system. For effective innovations in the system, it is recommended that linkages between actors be identified and mapped and enabling environment for innovations provided.
