Satellite mapping reveals extensive industrial activity at sea

Abstract The world’s population increasingly relies on the ocean for food, energy production and global trade 1–3 , yet human activities at sea are not well quantified 4,5 . We combine satellite imagery, vessel GPS data deep-learning models to map industrial offshore infrastructure across coastal waters from 2017 2021. find that 72–76% of fishing vessels publicly tracked, with much taking place around South Asia, Southeast Asia Africa. also 21–30% transport activity is missing public tracking systems. Globally, decreased by 12 ± 1% onset COVID-19 pandemic in 2020 had recovered pre-pandemic levels By contrast, were relatively unaffected during same period. Offshore wind growing rapidly, most turbines confined small areas but surpassing number oil structures Our industrialization reveals changes some extensive economically important sea.

Illuminating the multidimensional contributions of small-scale fisheries

Nature, Год журнала: 2025, Номер unknown

Sustainable development aspires to "leave no one behind"1. Even so, limited attention has been paid small-scale fisheries (SSF) and their importance in eradicating poverty, hunger malnutrition. Through a collaborative multidimensional data-driven approach, we have estimated that SSF provide at least 40% (37.3 million tonnes) of global catches 2.3 billion people with, on average, 20% dietary intake across six key micronutrients essential for human health. Globally, the livelihood 1 every 12 people, nearly half them women, depends partly fishing, total generating 44% (US$77.2 billion) economic value all landed. Regionally, Asian fish, support livelihoods supply nutrition largest number people. Relative capture sector (comprising large-scale fisheries), regions, African most catch nutrition, Oceania improve livelihoods. Maintaining increasing these contributions sustainable requires targeted effective actions, especially engagement fisherfolk shared management governance. Without governance focused SSF, marginalization millions fishers fishworkers will worsen. A study aimed revealing role shows they fishing affect world, among other important contributions.

Safeguarding marine life: conservation of biodiversity and ecosystems

Reviews in Fish Biology and Fisheries, Год журнала: 2022, Номер 32(1), С. 65 - 100

Опубликована: Март 1, 2022

Marine ecosystems and their associated biodiversity sustain life on Earth hold intrinsic value. Critical marine ecosystem services include maintenance of global oxygen carbon cycles, production food energy, sustenance human wellbeing. However are swiftly being degraded due to the unsustainable use environments a rapidly changing climate. The fundamental challenge for future is therefore safeguard biodiversity, function, adaptive capacity whilst continuing provide vital resources population. Here, we foresighting/hindcasting consider two plausible futures towards 2030: business-as-usual trajectory (i.e. continuation current trends), more sustainable but technically achievable in line with UN Sustainable Development Goals. We identify key drivers that differentiate these alternative develop an action pathway desirable, future. Key achieving will be establishing integrative across jurisdictions sectors), management supports equitable stewardship environments. Conserving require recalibrating our social, financial, industrial relationships environment. While requires long-term planning commitment beyond 2030, immediate needed avoid tipping points avert trajectories decline. By acting now optimise protection ecosystems, building upon existing technologies, conserving remaining can create best opportunity 2030 beyond.

Transnational Corporations, Biosphere Stewardship, and Sustainable Futures

Annual Review of Environment and Resources, Год журнала: 2022, Номер 47(1), С. 609 - 635

Опубликована: Март 9, 2022

Corporations are perceived as increasingly powerful and critically important to ensuring that irreversible climatological or ecological tipping points on Earth not crossed. Environmental impacts of corporate activities include pollution soils, freshwater the ocean, depletion ecosystems species, unsustainable use resources, changes air quality, alteration global climate. Negative social unacceptable working conditions, erosion traditional practices, increased inequalities. Multiple formal informal mechanisms have been developed, innovative examples biosphere stewardship resulted in progress. However, crisis underscores such efforts insufficient transformative change is urgently needed. We provide suggestions for aligning with argue requires more ambitious approaches taken by corporations, combined new formalized public governance governments.

A geopolitical-economy of distant water fisheries access arrangements

Abstract In recent decades, fishing fleets and effort have grown in aggregate throughout the waters of lower-income coastal countries, much which is carried out by vessels registered higher-income countries. Fisheries access arrangements (FAAs) underpin this key trend ocean fisheries their origins UNCLOS’s promise to establish resource ownership as a mechanism increase benefits newly independent island states. Coastal states use FAAs permit foreign state, firm, or industry association fish within its waters. This paper provides conceptual approach for understanding across global exploring potential deliver on UNCLOS. Illustrated with findings from multiple case studies, we advance developing geopolitical-economy that attends combination contingent context-specific economic, ecologic, geopolitical forces shape terms, conditions practices shaping persistent phenomenon industrial countries’

The Politics of Ocean Governance Transformations

Frontiers in Marine Science, Год журнала: 2021, Номер 8

Опубликована: Июль 2, 2021

Recently, oceans have become the focus of substantial global attention and diverse appeals for “transformation.” Calls to transform ocean governance are motivated by various objectives, including need secure rights marginalized coastal communities, boost ocean-based economic development, reverse biodiversity loss. This paper examines politics transformations through an analysis three ongoing cases: FAO’s voluntary guidelines small-scale fisheries; debt-for-“blue”-nature swaps in Seychelles; United Nations’ negotiations a high seas’ treaty. We find that not inevitable or apolitical. Rather, changes driven array actors with different objectives varying degrees power. Objectives articulated negotiated interactions may reassemble rights, access, control; however, there is also potential existing conditions further entrenched rather than transformed at all. In particular, our suggests that: (1) efforts situated contested, historical landscapes bias trajectory transformation, (2) power dynamics shape whose agendas narratives drive transformational change, (3) create uneven distributions costs benefits can facilitate stall progress toward intended goals. As competing interests over spaces continue grow coming decades, understanding processes which occur—and making transformative change more explicit—will be critical realizing equitable governance.
