European policy-makers are increasingly aware of the ecological and socioeconomic relevance of marine recreational fisheries (MRF), but there are still gaps in the information needed to achieve sustainable management. How is the current management of European MRF performed? Is it promoting the Ecosystem Approach to Fisheries (EAF)? The management of MRF in Europe was reviewed by analyzing how different European regulations align with the EAF in different geographic and administrative scales. Text mining tools were used to identify key concepts and analyze the text of legal regulations on MRF in the European Union (EU), Portugal, Spain and the United Kingdom (UK). Also, the Ecosystem Fisheries Legal Assessment (EFLA) framework was used to assess the alignment of the regulations with the EAF. The number of regulations about MRF in Spain and Portugal is higher than in the UK and the EU, probably because the relative higher importance of regional regulations in Spain and Portugal, and the limitations imposed to recreational fishers in marine protected areas (MPAs). The lack of specific regulations on MRF in the EU, and open-access in the UK for recreational fishers, except for Atlantic salmon Salmo salar, explain their lower number of regulations. The EFLA framework showed that the European public policies on MRF follow the EAF principles. Enough attention is payed to ecological components, but socio-economic sustainability could be improved. However, policy efficiency could be lower than expected because potential institutional misfits derived from the eventual confluence of different spatial scales.

The commitment by over 100 governments covering over 90% of the world's forests at the COP26 in Glasgow to end deforestation by 2030 requires more effective forest monitoring systems. The near real-time (NRT) change detection of forest cover loss enables forest landowners, government agencies and local communities to monitor natural and anthropogenic disturbances in a much timelier fashion than the thematic maps that are released every year. NRT deforestation alerts enable the establishment of more up-to-date forest inventories and rapid responses to unlicensed logging. The Copernicus Sentinel-2 satellites provide operational Earth observation (EO) data from multi-spectral optical/near-infrared wavelengths every five days at a global scale and at 10 m resolution. The amount of acquired data requires cloud computing or high-performance computing for ongoing monitoring systems and an automated system for processing, analyzing and delivering the information promptly. Here, we present a Sentinel-2-based NRT change detection system, assess its performance over two study sites, Manantlán in Mexico and Cartagena del Chairá in Colombia, and evaluate the forest changes that occurred in 2018. An independent validation with very high-resolution PlanetScope (~3 m) and RapidEye (~5 m) data suggests that the proposed NRT change detection system can accurately detect forest cover loss (> 87%), other vegetation loss (> 76%) and other vegetation gain (> 71%). Furthermore, the proposed NRT change detection system is designed to be attuned using in situ data. Therefore, it is scalable to larger regions, entire countries and even continents.

International audience ; Marine recreational fishing (MRF) is a high‐participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative requirement, estimates are only available for some countries. Here, data on numbers of fishers, participation rates, days fished, expenditures, and catches of two widely targeted species were synthesized to provide European estimates of MRF and placed in the global context. Uncertainty assessment was not possible due to incomplete knowledge of error distributions; instead, a semi‐quantitative bias assessment was made. There were an estimated 8.7 million European recreational sea fishers corresponding to a participation rate of 1.6%. An estimated 77.6 million days were fished, and expenditure was €5.9 billion annually. There were higher participation, numbers of fishers, days fished and expenditure in the Atlantic than the Mediterranean, but the Mediterranean estimates were generally less robust. Comparisons with other regions showed that European MRF participation rates and expenditure were in the mid‐range, with higher participation in Oceania and the United States, higher expenditure in the United States, and lower participation and expenditure in South America and Africa. For both northern European sea bass (Dicentrarchus labrax, Moronidae) and western Baltic cod (Gadus morhua, Gadidae) stocks, MRF represented 27% of the total removals. This study highlights the importance of MRF and the need for bespoke, regular and statistically sound data collection to underpin European fisheries management. Solutions are proposed for future MRF data collection in Europe and other regions to support sustainable fisheries management.
