SDG 14—Life Below Water—focuses on conserving and sustainably using the oceans, seas and marine resources, including coastal zones at the land-sea interface, for sustainable development. This goal draws attention to human interactions with these resources, especially in coastal cities and territories. Local and regional governments have a key role to play in approaching marine life, particularly with regard to the impact of urban growth and of solid and liquid waste discharges into coastal areas and the oceans. They have adopted policies, plans, incentives and strategies to protect the global common which is the ocean. More specifically, they are responsible for a series of actions that address at least five of the SDG 14 targets, which are: 14.1 (Marine pollution), 14.2 (Management, protection and restoration), 14.5 (Conservation), 14.7 (Small Island States and Low Developed Countries), and 14.b (Small-scale fishing). As the effects of human activities and urbanization transcend city boundaries, special attention is also paid to the policies implemented by regional governments, intermediary cities and small towns to apply territorial approaches to ecosystem conservation.
