Human impact and ocean stewardship

Human impacts on the oceans are considerable and rising.48 Climate change is deoxygenating, acidifying and warming the oceans, pollution such as fertiliser run-off from farms threatens many ecosystems, and overfishing is destabilising many ecosystems. There are also emerging impacts, such as the nascent deep-sea mining industry49 and initiatives to remove CO2 to the ocean to mitigate climate change. These impacts intersect in numerous ways:50 51 for instance, ocean biodiversity affecting climate.52 However, with effective knowledge-gathering and policy-making, it should be possible to minimise harms and create a sustainable future for the oceans.53 Artificial intelligence may have roles to play here, for instance in modelling the impacts of interventions.54

Future Horizons:

5-yearhorizon

Citizen scientists expand their role

Low-cost, accessible monitoring devices enable citizen scientists to significantly expand their role in tracking ocean ecosystems. Research is spurred by improved understanding of cultural connections to the sea, including the cultural heritage of the deep sea.

10-yearhorizon

A sustainable blue economy emerges

Understanding is sufficient for rational design of marine conservation interventions and of regulations for the sustainable blue economy. Standardised and reliable methods for conserving shallower ecosystems are developed. In many deep-sea ecosystems, however — such as hydrothermal vents or the abyssal plains — the pace of recovery is so slow (where possible at all), that the prevention of any degradation remains essential.

25-yearhorizon

AI and systematic analysis improve conservation

Earth-system models and artificial intelligence are used to simulate global-level interactions between the oceans, their ecosystems and the wider Earth system. Systematic analyses of biodiversity-conservation interventions demonstrate the key factors determining effectiveness of initiatives such as Marine Protected Areas. Transdisciplinary research, including social, anthropological, legal and economic expertise, establishes methods for estimating the financial value of ecosystem functions and services.

Better understanding of our impacts will come from improvements in monitoring, for instance by robotic surface vehicles,55 and in expanding our observations to the remote deeps.56 There is great potential for citizen scientists to contribute,57 both to ocean observations and to conservation.58 New blue industries like marine aquaculture may have key roles both in our economies and in marine conservation.59 Capacity-building and knowledge transfer will be crucial to understand all parts of the ocean, from the south to north, and shallow to deep.

Managing the oceans is a major geopolitical challenge.60 A key challenge is to determine, by leveraging scientific expertise and co-design, which kinds of policy interventions will be the most beneficial and have the fewest unintended consequences. The BBNJ (Biodiversity Beyond National Jurisdiction) treaty,61 once ratified, will regulate the sustainable use of marine genetic resources (MGR), environmental impact assessments (EIA) and area-based management tools (AMBTs) such as Marine Protected Areas in the ocean outside national boundaries.62 Successes in ocean diplomacy, such as with the adoption of the BBNJ treaty, will need to be built upon to assist future ocean science and conservation efforts.63 Conservationists are increasingly exploring radical ideas such as granting legal rights to nature.64

Human impact and ocean stewardship - Anticipation Scores

The Anticipation Potential of a research field is determined by the capacity for impactful action in the present, considering possible future transformative breakthroughs in a field over a 25-year outlook. A field with a high Anticipation Potential, therefore, combines the potential range of future transformative possibilities engendered by a research area with a wide field of opportunities for action in the present. We asked researchers in the field to anticipate:

  1. The uncertainty related to future science breakthroughs in the field
  2. The transformative effect anticipated breakthroughs may have on research and society
  3. The scope for action in the present in relation to anticipated breakthroughs.

This chart represents a summary of their responses to each of these elements, which when combined, provide the Anticipation Potential for the topic. See methodology for more information.
