. Flexible and rapid policy reform and management adaptation will help to meet sustainability targets , and may only be available for countries with the scientific, technical and institutional capacity to implement these  . Other adaptation options include 'follow the food' thereby migrating further , provision of alternative livelihoods , increasing ecosystem resilience by rebuilding coastal mangroves  and riparian areas of freshwater ecosystems  and autonomous adaptations, such as harvesting gear modifications to access new target species , practice change, and early-warning systems . Adaptive capacity will change with country, region, scale  of fishery, jurisdiction, and resource dependence . While shifting fishing fleets or herding may be an adaptation option to follow resources, limits to feasibility include institutional, legal, financial and logistical barriers such as costs of sourcing food and operational economic viability ; this could potentially lead to maladaptation through increased GHG emissions from fuel usage and cultural displacement from traditional fishing and herding lands. Overall, decreases in GHG emissions under future scenarios would reduce increases in global temperatures and limit species shifts, thereby lowering the likelihood of conflicts and food insecurity .
