growth. The contribution of sustainable fisheries to the global GDP was around 0.1% per year. Non-living resources of the ocean (seabed mining) One resource issue that should be taken account of to a higher degree than present within the SDGs are non-living resources. Mining will always be a controversial though necessary activity. The balance between mining and marine environment will be one that can be assisted by a greater focus from SDG 14. Marine minerals include sea-dredged and seabed minerals. Sea-dredged minerals are normally extracted by dredging operations within coastal zones, to maximum sea depths of about 200 m. Minerals normally extracted from these depths include sand, silt and mud for construction purposes, mineral rich sands such as ilmenite and diamonds. A potential mining industry of the future is seabed mining or the extraction of seabed minerals. Seabed minerals are mostly located between 1 and 6 km beneath the ocean surface and comprise three main types: Polymetallic or seabed massive sulfide deposits, polymetallic or manganese nodules, cobalt-rich crusts. At the present time (2021) there is no commercial mining of seabed minerals. Mining of the seabed is a controversial issue, as it will inevitably have some deleterious environmental and biospheric impacts. Some argue that there should be a total ban on seabed mining. Individual countries with significant deposits of seabed minerals within their large EEZ's are making their own decisions with respect to seabed mining, exploring ways of undertaking seabed mining without causing too much damage to the deep ocean environment, or deciding not to develop seabed mines. Target 14.a: Increase scientific knowledge, research and technology for ocean health The full title of Target 14.a is: "Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing States and least developed countries". This target has one indicator: Indicator 14.a.1. is the "proportion of total research budget allocated to research in the field of marine technology". This indicators aims to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing States and least developed countries. Target 14.b: Support small scale fishers The full title of Target 14.b is: "Provide access
