Unselective, unsustainable, and unmonitored trawl fisheries?
In 2016, the term UUU (unselective, unsustainable and unmonitored) fishing was developed and a Resolution of the World Conservation Congress, adopted by Members, tasked IUCN’s Species Survival Commission with reporting on the concept. The resulting situation analysis utilises the trawl fisheries of China, Thailand and Vietnam to explore how some of the issues associated with UUU fishing can be linked back to these three elements. The report found considerable variation in each component of UUU across the case study countries but that uncontrolled fishery development resulting in excess fishing capacity is commonly a root cause, leaving long standing impacts which have proven very challenging to solve. Whilst the report does not provide recommendations for action, it does identify 14 areas where further work would help accelerate progress on sustainable use, the protection of species of conservation concern and help safeguard the marine ecosystem.
Designing and managing protected and conserved areas to support inland water ecosystems and biodiversity
Inland waters – such as rivers, lakes and other wetlands – are among the most biodiverse ecosystems on the planet. They are also the most threatened; almost one in three species is at risk of extinction and monitored populations of freshwater species have declined by 85% since 1970. The loss of these ecosystems has cascading effects on human livelihoods, cultures and our overall well-being. While protected and conserved areas can play an important role in bending the curve of inland water biodiversity and ecosystem loss, they have rarely been designed, designated, and managed for that purpose. Motivated by the Kunming-Montreal Global Biodiversity Framework’s inclusion of inland waters in the target to conserve 30% of the planet by 2030, this report provides guidance in employing protected areas and other effective area-based conservation measures to benefit these ecosystems and the biodiversity they support. Through a series of case studies and synthesized research, it highlights how integrating the unique needs of inland waters into area-based strategies can improve conservation effectiveness across all realms, build climate resilience and sustain critical ecosystem services.
Categorias e critérios da EICAT da UICN : primeira edição
Como resposta a estas questões, foi desenvolvida uma classificação padronizada dos táxones exóticos, baseada na magnitude dos seus impactos ambientais. EICAT (Classificação do Impacto Ambiental de Táxones Exóticos) o trata-se de um método simples, objetivo e transparente para classificar táxones exóticos de acordo com a magnitude dos seus impactos prejudiciais para o ambiente nas áreas recetoras. Com base na evidência dos impactos causados nos táxones nativos nas áreas em que foram introduzidos, os táxones exóticos são classificados em uma de cinco categorias de impacto. Cada uma destas cinco categorias de impacto representa uma magnitude de impacto diferente, dependendo do nível de organização biológica (indivíduo, população ou comunidade) sobre a qual o impacto é exercido e da reversibilidade do mesmo.
State of West African marine protected areas 2022
The coastal zone of West Africa extends approx. 6,000 km, from Mauritania in the north, passing through the deeply indented coasts of the islands and estuaries, then the lagoon coasts and the coastal strips of the Gulf of Guinea, up to Nigeria. The small island state of the Cabo Verde Islands, volcanic and mountainous, completes this geography. These coastal areas are characterized by globally significant biodiversity. But the marine ecosystem and coastal communities face many challenges, namely illegal, unreported and/or unregulated fishing, pollution, uncontrolled coastal development, etc., which harm habitats and species. This report takes stock of the situation, while offering in-depth analyses as well as recommendations on the opportunities and challenges in terms of marine protected areas in the region.
État des aires marines protégées d’Afrique de l’Ouest 2022
La zone côtière de l’Afrique de l’Ouest s’étend sur environ 6 000 km, depuis la Mauritanie au nord, en passant par les côtes rofondément découpées des îles et des estuaires, puis les côtes lagunaires et les cordons littoraux du Golfe de Guinée, jusqu’au Nigéria. Le petit État insulaire des îles du Cabo Verde, volcanique et montagneux, complète cette géographie. Ces zones côtières sont caractérisées par une biodiversité d’importance mondiale. Mais l’écosystème marin et les communautés côtières sont confrontés à de nombreux défis : pêche illégale, non déclarée et/ou non réglementée, pollution, développement côtier incontrôlé, etc., qui portent atteinte aux habitats et aux espèces. Cette publication fait un état des lieux, tout en proposant des analyses approfondies ainsi que des recommandations sur les opportunités et défis en matière d’aires marines protégées dans la région.
UICN Painel do Rio Doce
O desastre de Fundão em 2015 foi um dos maiores desastres ambientais da história do Brasil. O rompimento da barragem próxima à cidade de Mariana liberou cerca de 39 milhões de m3 de rejeitos, que percorreram 670 km até chegar ao Oceano Atlântico. Nesse trajeto, os rejeitos resultaram em 19 óbitos, devastaram ecossistemas e interromperam modos de vida e meios de subsistência de milhares de pessoas. Em apoio às atividades de restauração, a UICN instituiu o Painel do Rio Doce, um Painel Independente de Assessoria Técnica e Científica (Independent Scientific and Technical Advisory Panel, ISTAP) com a missão de prestar assessoramento especializado em diversas áreas. Composto por cientistas nacionais e internacionais de renome, o Painel atuou de 2017 a 2022. Este relatório descreve o trabalho do Painel e suas influências e impactos de longo prazo.
IUCN Rio Doce Panel
The Fundão disaster in 2015 was one of the biggest environmental disasters in Brazil’s history. The collapse of the dam near the city of Mariana released around 39 million m3 of tailings, which travelled 670 km to reach the Atlantic Ocean. Along the way, the tailings resulted in 19 deaths, devastated ecosystems and disrupted the livelihoods of thousands of people. In support of restoration activities, IUCN established the Rio Doce Panel, an Independent Scientific and Technical Advisory Panel (ISTAP) with the mission to provide expert advice in a range of areas. Composed of renowned national and international scientists, the Panel served from 2017 to 2022. This report describes the work of the Panel and its long-term influences and impacts.
Diretrizes para o manejo de organismos vivos confiscados
O comércio ilegal de animais silvestres aumentou dramaticamente na última década; no entanto, os esforços de fiscalização destinados a mitigar essa ameaça também o fizeram. O sucesso na aplicação da lei frequentemente envolve a apreensão e o confisco de espécies selvagens de diversos taxa de plantas, animais e fungos. Essas apreensões podem incluir partes de espécimes não vivos na forma de artefatos, alimentos ou produtos medicinais, mas, em muitos casos, envolvem indivíduos vivos. Com confiscos cada vez mais frequentes e muitas vezes um grande número de indivíduos envolvidos, é importante seguir as melhores práticas na abordagem de manejo para maximizar o papel na conservação e o bem-estar individual dessas plantas e animais. Este documento tem como objetivo fornecer orientação sobre essas melhores práticas.
Improving the sustainability of freshwater services
The IUCN Global Standard for Nature-based Solutions™ self-assessment tool is a recent framework for assessing the effectiveness of a potential NbS intervention against eight good practice principles, associated with 28 criteria. This report brings an overview of the NbS Global Standard assessment outcomes and process at the Minas-Rio operation, an iron ore mining facility site operated by Anglo American in Brazil. The objective of the assessment was to analyse the measures taken by Anglo American pertaining to the enhancement of water security, with specific emphasis on water quality and supply. This assessment aimed to gauge the alignment of those measures with the established criteria in the NbS Standard.
Planning for human-wildlife coexistence
The Iguaçu National Park (INP), in Brazil, and its sister park Iguazú National Park in Argentina constitute one of the most significant remaining remnants of the Interior Atlantic Forest on the Argentina-Brazil border. The Iguaçu National Park is a UNESCO World Heritage site of roughly 185 000 ha, located in the State of Paraná, in southern Brazil. The national park contains semi-deciduous, sub-tropical rainforests and many charismatic species, including jaguar Panthera onca, puma Puma concolor and the tapir Tapirus terrestris. The area around the national park has mainly been altered due to heavy logging and the intensification and expansion of agriculture (mostly corn and soy), and rural settlements. On the national park’s boundaries, wildlife comes into contact with people with negative interactions arising. In 2018, Projeto Onças do Iguaçu (the Jaguars of Iguaçu Project, and hereafter “the project”) was initiated, to continue the jaguar population surveys carried out by previous projects, such as “Carnívoros do Iguaçu,” and expand outreach activities, including providing technical assistance to ranchers, engaging with local communities and providing education regarding jaguars in the region.
This case study will cover the process of planning for coexistence undertaken by this project.
Using a conflict framework to identify the correct problem to manage
In the Cerrado biome of the Mato Grosso do Sul state in Brazil, honey production is an important activity. The state has the country’s highest production amount per hive/year. Beekeepers place hives along the edge of native vegetation to ensure bees visit the wildflowers. However, large areas of the Cerrado biome have been converted to pasture or agriculture, resulting in the biome being highly fragmented and native vegetation is increasingly found in small patches. The iconic giant armadillo Priodontes maximus still survives in some of these fragments, often unnoticed due to their solitary, nocturnal, and fossorial (burrowing) habits. Where apiaries have been established along the edge of patches of native vegetation, giant armadillos have learnt to knock over the beehives, giving them access to the bee larvae, resulting in substantial economic losses to the beekeepers through damage to hives. This unfortunately can lead to retaliatory killings as a giant armadillo can completely destroy a beekeeper’s livelihood in a matter of weeks.
These negative interactions became apparent to the Giant Armadillo Conservation Program’s (hereafter “the project”) staff, following initial research in the Cerrado. The project, therefore, sought to investigate the situation further, before seeking to manage the situation.
The Bangladesh Sundarbans : a photoreal sojourn
The Sundarbans, the immense tidal mangrove forests of Bangladesh, are a mosaic of islands of different shapes and sizes, perennially washed by brackish water swirling in and around the endless and mind-boggling labyrinths of twisting water channels. This is the place where mainland Bangladesh meets the Bay of Bengal, making the area a globally unique ecological niche. This full colour publication has captured the Sundarbans in all their glory, and gives us a glimpse of its animals and plants, as well as its social and spiritual life.
