Blue-Green Frontiers, The Ridge-to-Reef Continuum

About this session

The ocean does not begin at the shoreline, and the land does not end there. Between ridge and reef, ecological processes are continuous. Sediment from degraded watersheds smothers coral; agricultural runoff drives algal blooms; mangrove loss strips fisheries and storm protection. Freshwater discharge shapes coastal salinity, temperature, and chemistry. Carbon stored in peatland, mangrove, seagrass, and salt marsh is one system that accounting treats as four. Fisheries depend on watershed health far upstream; agriculture depends on an ocean-regulated climate.

Yet conservation, agricultural, and ocean finance remain separate, with different standards, frameworks, investors, policies, and metrics. At the land-sea interface—where ecological leverage is greatest—governance is most fragmented. This is inefficient and ecologically costly: siloed investment allows the most biodiverse zones to degrade faster than either domain can address.

ASEAN holds a vast land-sea continuum. The Restore Nature Initiative and Indonesian Island Restoration sit at this interface. The question is whether they can be financed and governed as continuous systems.

This session asks whether investors, policymakers, scientists, and communities will redesign their architectures to match ecology—and who pays the cost if they do not.
