Resumen (Objetivo). Se evaluó el manglar de Chacarita en el Pacífico Central de Costa Rica, a través de la composición florística y las poblaciones de moluscos asociados de interés comercial, con el fin de proponer actividades de aprovechamiento sustentables en el manglar. (Metodología). Mensualmente y durante un año, se realizaron visitas al área de estudio, con el propósito de establecer una base florística de árboles de mangle y medir el almacenamiento de carbono en el lugar, además, de recolectar moluscos bivalvos para analizar el estado de las poblaciones, con base en las abundancias de organismos hallados y otras características como las longitudes y la masa de estos. En los mangles, se obtuvo el diámetro de la altura de pecho (DAP en cm), la altura (m), el índice de valor de importancia (IVI) y las reservas de carbono (Mg C·ha-1). En cuanto a los moluscos, se examinaron cuatro especies de interés comercial, evaluando la longitud (cm), la masa (g) y el índice gonadosomático. Finalmente, se realizaron valoraciones económicas de los datos obtenidos en el manglar, del turismo e información histórica de pesca para el acopio de Chacarita. (Resultados). Se hallaron cinco especies de mangles, Rhizophora mangle, Rizophora racemosa, Laguncularia racemosa, Avicennia germinans y Pelliciera rhizophorae; P. rhizophorae fue la de mayor índice de valor de importancia. Se obtuvo un almacenamiento de carbono equivalente a 78.49 Mg C·ha-1. Se contabilizaron 357 organismos, de los cuales el 18 % correspondió a Anadara similis, 37.5 % a Anadara tuberculosa, 41.46 % a Leukoma spp. y 3.08 % a Mytella guyanensis. Tomando en cuenta el valor económico de las reservas de carbono y los moluscos bivalvos presentes en los muestreos, se obtuvieron valoraciones económicas de 9812.63 USD·ha-1 y 28 USD·ha-1, respectivamente. (Conclusiones). Las bajas densidades poblacionales de moluscos, especialmente del género Anadara, hacen necesario establecer medidas de gestión que permitan recuperar las poblaciones de estos. La presente investigación propone actividades de aprovechamiento sustentables, como turismo comunitario con fines educativos y culturales.

Resumo (Objetivo). O mangue de Chacarita, no Pacífico Central da Costa Rica, foi avaliado por meio da composição florística e das populações de moluscos associados de interesse comercial, com o objetivo de propor atividades de uso sustentável no mangue. (Metodologia). Foram feitas visitas mensais à área de estudo durante um ano para estabelecer uma base florística de árvores do mangue e medir o armazenamento de carbono no local, bem como para coletar moluscos bivalves para analisar o status das populações, com base na abundância de organismos encontrados e em outras características, como comprimento e massa de tais organismos.

Abstract (Objective). The floristic composition and populations of associated molluscs of commercial interest of the Chacarita mangrove forest on the Central Pacific of Costa Rica were evaluated to guide proposals for sustainable exploitation activities in the mangrove forest. (Methodology). Monthly visits to the study area were conducted for one year to establish a floristic baseline of mangrove trees and measure carbon storage. Additionally, bivalve molluscs were collected to analyze the state of their populations based on the abundances of organisms found, as well as other characteristics such as length and mass. Data regarding the mangrove trees included their diameter at breast height (DBH, cm), height (m), importance value index (IVI), and carbon reserves (Mg C·ha-1). Four mollusc species of commercial interest were analyzed, using data on their length (cm), weight (g), and gonodosomatic index. Economic evaluations were also conducted using data obtained from the mangrove forest, as well as tourism and historical fishing data for the collection of Chacarita. (Results). Five species of mangroves were identified: Rhizophora mangle, Rizophora racemosa, Laguncularia racemosa, Avice germinans, and Pelliciera rhizophorae, while P. rhizophorae had the highest importance value index. The study revealed a carbon storage equivalent to 78.49 Mg C·ha-1. A total of 357 organisms were counted, with Anadara similis accounting for 18% of the total count, followed by Anadara tuberculosa (37.5%), Leukoma spp. (41.46%), and Mytella guyanensis (3.08%). When considering the economic value of carbon stocks and the bivalve molluscs obtained from the samples, economic valuations of 9,812.63 USD·ha-1 and 28 USD·ha-1 were determined, respectively. (Conclusions). The low population densities of molluscs, particularly those belonging to the Anadara genus, necessitate the establishment of management measures to facilitate the recovery of these mollusk populations. This research proposes sustainable use activities such as community tourism for educational and cultural purposes.

Abstract (Introduction): Coastal areas constitute the interface between land and marine environments, connected through multiple natural and socioecological processes that contribute to human well-being. (Objective): Identify land and marine uses and activities with mutual implications and biophysical processes in the northern region of the Bonaerense Coastal Ecosystem (Argentina), in order to evaluate the degree of compatibility or conflict between these activities, with emphasis on the fishing activity. (Methodology): The land-sea-land (T-M-T) methodological analysis was applied. Uses and activities (U&A) and biophysical processes of marine and land origin were determined. Interactions between marine-land and biophysical processes T-M-T were identified for further categorization and analysis. (Results): A total of 121 U&A sea-land-sea (L-S-L) interactions related to fishing were detected. Medium conflicts were mainly caused by competition for space or resources and were associated with the coexistence of U&A (tourism, fishing, and communication activities), both spatially and temporally. Of the total, 68 negative interactions were observed between biophysical processes and U&A L-S-L, which were linked to climatic events and the effects of climate change (variation in sea surface temperature, atmospheric and oceanic circulation, as well as variations in sediment transport and coastal erosion). (Conclusions): The analysis carried out constitutes an advancement in the study of U&A T-M-T in coastal-marine areas of the Atlantic coast and their interactions, with emphasis on fishing activities, as a contribution to their management with an ecosystemic approach.

Resumen (Introducción): Los espacios litorales constituyen la interfaz entre los ambientes terrestres y marinos, conectados por múltiples procesos naturales y socioecológicos, proporcionando bienes y servicios ecosistémicos para el bienestar humano. (Objetivo): Identificar los usos y actividades tanto terrestres como marinos con implicancias mutuas y los procesos biofísicos en la región norte del Ecosistema Costero Bonaerense (Argentina), con el fin de evaluar el grado de compatibilidad o conflicto entre estas actividades, con énfasis en el sector pesquero. (Metodología): Se aplicó el análisis metodológico tierra-mar-tierra (T-M-T). Se determinaron los usos y actividades (UyA), así como procesos biofísicos de origen marino y terrestre. Se identificaron las interacciones entre UyA marinos y terrestres, y procesos físicos T-M-T, para su posterior categorización y análisis de las interacciones previamente identificadas. (Resultados): Se notaron 121 interacciones de UyA T-M-T vinculadas con la pesca. Predominaron los conflictos medios por competencia de espacio o recursos y se relacionaron con la coexistencia espacial y temporal de UyA (turísticas, pesquera y comunicaciones). Se detectaron 68 interacciones negativas entre los procesos biofísicos y UyA asociados a eventos climáticos e impactos derivados del cambio climático (modificaciones en la temperatura superficial del mar, circulación atmosférica y oceánica, así como variaciones en el transporte de sedimentos y erosión costera). (Conclusiones): El análisis efectuado constituye un avance en el estudio entre UyA T-M-T en zonas litorales costero-marinas de la costa atlántica y de sus interacciones, con énfasis en la actividad pesquera, como aporte a la gestión de aquellos, con un enfoque ecosistémico.

The number of people on Earth and human activities are currently taking on frightening proportions with far-reaching consequences for our planet, its biodiversity and ultimately the human race itself. Ten thousand years ago, humans represented 1% of the total biomass of all land vertebrates. The rest was made up by wild animals. Currently, humans, livestock and pets make up 99% of terrestrial vertebrate biomass, while wild animals represent only 1%. It took millennia for the human population to reach the 1 billion mark and that only by 1890. By 1960, however, the world population had grown to 3 billion. Today there are 8 billion people living on our planet. According to Population Matters, the world population will be approximately 10,4 billion by the end of this century, despite the gradual decline in the growth rate in some countries. There is only a 23% chance that the total population growth rate will tail off before 2100. The population of the 47 least developed countries is likely to triple between 2017 and 2100 to around 3 billion. There are currently 62 million people in South Africa. About 67,9% of our population (in 2021) live in urban areas. The South African population grew by 0,87% in 2023. The fertility rate is 2,30 (2023). It is estimated that by 2050 75,5 million people will be living in South Africa, with 8 out of every 10 people living in urban areas, which would significantly increase the pressure on infrastructure. The Global Footprint Network states that humans currently use the resources of 1,75 Earths. If the situation does not improve, by 2050 we would need the equivalent of three Earths to survive. More than 4 billion people will have little or no water by 2050, and South Africa even now has been classified as a "water-stressed" country. Medical science is continually contributing to more babies surviving their entry into the world and to our living increasingly longer. Life expectancy has risen from 46 years in 1950 to 73,2 years in 2023. By 2050 it will be 77 years. What can be done? Empowerment of women is important. Population growth can be curbed to a reasonable extent by giving more girls access to education. This certainly does not mean that girls or women alone should be held responsible for the current population growth, but much more will have to be done about sex education, women's rights will have to be actively promoted and there will have to be better provision and use of contraceptives. Obviously, these issues should be approached and handled with due caution. In this regard, countries such as Thailand and South Korea have, in the recent past, proved that good education may result in lower birth rates. In Africa, women with no education have an average of 5,4 children; women who completed high school an average of 2,7 children and women with tertiary education an average of 2.2. In Nigeria, every year of school attendance by girls cuts the birth rate by a tenth. In addition, intensified efforts to reform economies and societies should be considered. For the sake of the survival of the human species and the sustainability of the Earth, ecological and economic justice and the empowerment ofwomen have to be encouraged. The Millennium Project - a global participatory think tank that was founded in 1996 under the auspices of the American Council for the United Nations University, but which became independent in 2009 and has since grown into a global network of institutions and individuals - aims to improve humankind's prospects for a better future. It recommends, among other things, the following: • Support a policy aimed at improving the survival of children, responsible family planning and educational opportunities for (especially) girls. • Improve methods that will ensure skills and employment opportunities for young people, as well as care and services for the elderly. • Implement the UN's urban agenda. • Create enough smart cities where citizens with urban intelligence can help in eco-smart ways with the necessary improvements in the city. • Increase training in resilience, and improve disaster prediction and management. • Provide guidance for people about urban ecology. • Intensify research and development in saltwater agriculture (halophytes or salt plants) on coastlines to produce food for humans and animals, biofuel and pulp for the paper industry, and to absorb carbon dioxide (CO2). This will ease the pressure on freshwater agriculture. • Improve agricultural and irrigation management. • Invest in precision agriculture and aquaculture. • Reduce food losses from the "farm to the mouth" (one third or 1,3 billion tons of agricultural production is wasted in this way every year). • Establish seaweed to restore wild fish populations along coastlines. The World Bank estimates that 90% of marine life is completely depleted. • Expand the production of insects for animal feed and human diets (insects have a low environmental impact, and 2 billion people already supplement their diet with insects today). • Encourage vegetarianism. Although there are more ways to address these important global challenges, responsible family planning remains one of the most important. This is an extremely sensitive issue for many people (especially in Africa), but if it is not promoted in a humane, informed and responsible way, the sustainability of life on our planet will increasingly come under tremendous pressure in various respects.

Die aantal mense op aarde en hulle/ons aktiwiteite neem tans skrikwekkende afmetings aan met wydlopende gevolge vir ons planeet, biodiversiteit en uiteindelik onsself. Die moderne mens het sy teenwoordigheid op die aarde en die benutting van hulpbronne baie lank as sy onaantasbare reg gesien. Die huidige uitwerking van byvoorbeeld bevolkingsgroei en besoedeling versteur die aarde se natuurlike ritme in so 'n mate dat ons nou nie meer op 'n kitsoplossing kan hoop nie. Die mens se getalle neem teen so 'n tempo toe dat dit nie net nadelig vir die planeet is nie, maar ook vir die mensdom self. Wat kan gedoen word? Bemagtiging van vroue speel 'n belangrike rol. Dit beteken beslis nie dat meisies en vroue alleen vir die huidige bevolkingsgroei verantwoordelik gehou moet word nie. Die bevolkingsgroei kan egter in 'n redelike mate vertraag word deur veral meer meisies toegang tot onderwys en opleiding te gee - asook hul lewensomstandighede te verbeter. Ook sal daar heelwat meer aan seksopvoeding gedoen moet word, vroueregte sal daadwerklik bevorder moet word en daar sal beter voorsiening en gebruik van voorbehoedmiddels moet wees. Uiteraard moet hierdie kwessies met die nodige omsigtigheid benader en hanteer word. In hierdie verband kan onder andere Thailand en Suid-Korea genoem word wat in die onlangse verlede bewys het dat goeie onderwys geboortesyfers laat daal. In Afrika het vroue wat geen onderwys ontvang nie, gemiddeld 5,4 kinders; vroue wat hoërskool voltooi het gemiddeld 2,7 kinders en vroue wat tersiêre studie deurloop het, gemiddeld 2,2 kinders. In Nigerië sny elke jaar wat meisies skool bywoon, die geboortesyfer met 'n tiende. Hiermee saam sal daar ook verskerpte pogings moet wees om ekonomieë en samelewings te hervorm. Ter wille van die mens se voortbestaan en die volhoubaarheid van lewe op aarde moet ekologiese en ekonomiese geregtigheid, en die bemagtiging van vroue aangemoedig word.

ABSTRACT Overfishing, industrial fishing and climate change generate impacts that affect the marine fishery resource, the main source of income and food for coastal populations of artisanal fishers. The creation of conditions that increase the adaptive capacity of fishers will decrease their vulnerability to impacts. This research proposes to determine an Exclusive Zone for Artisanal Fishing-ZEPA as a strategy for sustainable management of fishery resources and climate adaptation for artisanal fishers in the study area. Marxan was used to identify three scenarios for the location of the ZEPA and participatory mapping was carried out with fishers to obtain the fourth scenario. High similarity was found between scenarios 2 and 4, which shows that the scientific (Marxan) and participatory (population) approaches coincide in the location of the ZEPA. The final ZEPA was located in the coastal marine zone of the municipalities of Tumaco and Francisco Pizarro, with a total area of 2,008 km2. Included important conservation targets for artisanal fisheries such as artisanal fishing grounds, ecosystems (mangroves, beaches and estuaries), areas of occurrence of species (seerfish, snappers, sea bass, piangua, marmoset shrimp) among others. More than 80 % of the fishers agreed that the strategy would help reduce their vulnerability to threats such as climatic phenomena, overfishing, pollution, among others. The contribution to climate change adaptation of the study area’s population is highlighted.

RESUMEN La sobrepesca, la pesca industrial y el cambio climático generan impactos que afectan al recurso pesquero marino, la principal fuente de ingreso y alimento de las poblaciones costeras de pescadores artesanales. La creación de condiciones que incrementen la capacidad de adaptación de los pescadores disminuirá su vulnerabilidad a los impactos. Esta investigación propone determinar una Zona Exclusiva de Pesca Artesanal-ZEPA como estrategia de manejo sostenible de los recursos pesqueros y de adaptación climática para los pescadores artesanales del área de estudio. Se utilizó el programa Marxan para identificar tres escenarios para la ubicación de la ZEPA y se realizó una cartografía participativa con pescadores para obtener el cuarto escenario. Se encontró similitud alta entre el escenario 2 y 4, lo que muestra que el enfoque científico (Marxan) y participativo (población) coinciden en la ubicación de ZEPA. La ZEPA definitiva se ubicó en la zona marino costera de los municipios de Tumaco y Francisco Pizarro, con un área total de 2 008 km2. Incluyó objetos de conservación importantes para la pesca artesanal como caladeros de pesca artesanal, ecosistemas (manglares, playas y estuarios), áreas de ocurrencia de especies (sierra, pargos, corvina, piangua, camarón tití), entre otros. Se identificó que más de 80 % de los pescadores estuvo de acuerdo en que la estrategia le aportaría a reducir su vulnerabilidad frente a amenazas como fenómenos climáticos, sobrepesca, contaminación, entre otros. Se resalta la contribución a la adaptación al cambio climático de la población del área de estudio.

Abstract This work presents the first results obtained from developing an experimental program that aims to generate a local frame of reference for the fatty acid profiles of the main resources available in the lower basin of the Colorado river (Buenos Aires district). In this case, the purpose was to identify the fatty acid composition of fish resources and evaluate the main transformations they underwent during cooking. Replicas of archaeological vessels were made, marine fish of different species (sea catfish, whitemouth croaker, narrownose smooth-hound, conger eel, and whiting) were boiled, and the fatty acids of the raw and cooked meat, the cooking liquid, and those of the contents on the internal walls of the vessels were measured. The results obtained showed that fatty acids could be detected in all samples. However, if those identified in the raw meat of each species are compared with those detected after boiling, it is observed that the cooking event generated the loss and/or degradation of some fatty acids, mainly unsaturated ones. Fatty acids (e.g., stearic, palmitic, and oleic acid) present in most food resources (e.g., herbivores and vegetables) were preserved in the vessels. However, fatty acids detected in the vessels such as the polyunsaturated belonging to the C20 group of sea catfish and whitemouth croaker, the eicosenoic acid of sea catfish, and the monounsaturated of the C22 group identified for the conger eel could be considered diagnostic fatty acids of marine fish.

Resumen En este trabajo se presentan los primeros resultados obtenidos del desarrollo de un programa experimental que tiene como objetivo generar un marco de referencia local de los perfiles de ácidos grasos de los principales recursos disponibles en el curso inferior del río Colorado (Pcia. de Buenos Aires). En este caso, el propósito fue conocer la composición de ácidos grasos de recursos ictícolas y evaluar las principales transformaciones que estos sufren durante la cocción. Para ello, se confeccionaron réplicas de vasijas arqueológicas, se hirvieron peces marinos de distintas especies (bagre de mar, corvina rubia, gatuzo, congrio y pescadilla) y se analizaron los ácidos grasos de la carne cruda y cocida, del líquido de cocción y de los contenidos en las paredes internas de las vasijas. Los resultados obtenidos evidenciaron que en todas las muestras de peces se pudieron detectar ácidos grasos. Sin embargo, si se comparan los identificados en la carne cruda de cada especie con los detectados con posterioridad al hervido, se observa que el evento de cocción generó la pérdida y/o degradación de algunos de ellos, principalmente de los ácidos insaturados. En las vasijas se preservaron los ácidos grasos (e.g., ácido esteárico, palmítico y oleico) que comúnmente están presentes en la mayoría de los recursos alimenticios (e.g., herbívoros, vegetales). No obstante, los ácidos grasos detectados en las vasijas como los poliinsaturados pertenecientes al grupo C20 de bagre de mar y corvina rubia, el ácido eicosenoico de bagre de mar y el monoinsaturado del grupo C22 identificado para el congrio podrían ser considerados ácidos grasos diagnósticos de peces marinos.

Resumo Este artigo descreve os impactos ambientais da produção de uma única muda em viveiros florestais de distritos selecionados (Haripur, Abbottabad e Manshera) da divisão Hazara, de Khyber Pakhtunkhwa, Paquistão, usando a abordagem de avaliação do ciclo de vida (ACV). Este estudo baseou-se na abordagem “do berço ao portão”, que se inicia na fase pré-viveiro e progride em direção ao viveiro principal antes do transplante das mudas para o local de plantio. Os dados ou inventário de ciclo de vida (ICV) da produção de mudas foram coletados por meio de questionários e reuniões pessoais com o gerente e os trabalhadores dos viveiros florestais sobre o consumo de diferentes insumos, como energia elétrica, diesel, fertilizantes, herbicidas, sacos de polietileno, adubo orgânico e consumo de água. O software SimaPro, versão 8.5, e o modelo ambiental CML2000, v2.05, foram aplicados para realizar a avaliação de impacto do ciclo de vida (AICV) de uma única produção de mudas em viveiros florestais na área de estudo. Em consonância com os objetivos do estudo, os dados primários relativos às entradas e saídas dos viveiros foram coletados de 35 viveiros na área de estudo por meio de um método de questionário aleatório. Além disso, dados secundários foram obtidos de bancos de dados online, como Eco-invent v.3.2 CORRIM e literatura publicada revisada por pares. Para este estudo, foi considerada uma unidade funcional de uma única plântula. Os dados médios ponderados de produção foram modelados no software de modelagem ambiental mais recente, ou seja, SimaPro, v.8.5, para 10 impactos ambientais mais desejados pela US-EPA, como potencial de aquecimento global (PAG), depleção abiótica (DA), potencial de eutrofização (PE), potencial de acidificação (PA), ecotoxicidade de água doce (EAD), ecotoxicidade da água marinha (EAM), ecotoxicidade terrestre (ET), destruição da camada de ozônio (DCO), oxidação fotoquímica (OF) e toxicidade humana (TH). Os resultados mostraram que o maior impacto ambiental causado por uma única muda foi a ecotoxicidade da água marinha (11,31360 kg 1,4-DB eq), seguido pelo potencial de aquecimento global (0,02945 kg CO2 eq) e toxicidade humana (0,01227 kg 1,4-DB eq) eq). A principal razão para esses ônus ambientais foi o uso de fertilizantes sintéticos em viveiros florestais e o consumo de combustíveis fósseis nas atividades de mecanização e transporte de viveiros. A demanda total acumulada de energia para uma única muda foi de 0,800 MJ, com mais de 90% de contribuição de recursos energéticos de combustíveis fósseis, como gasolina e diesel. Portanto, é altamente recomendável usar recursos de energia renovável e fertilizantes orgânicos em vez de fertilizantes químicos em viveiros florestais para evitar e minimizar as emissões de gases de efeito estufa (GEE) e outras emissões tóxicas na área de estudo.

Abstract This article describes the environmental impacts of producing a single seedling in forest nurseries of selected districts (i.e., Haripur, Abbottabad, and Mansehra) of Hazara Division of Khyber Pakhtunkhwa, Pakistan using the life cycle assessment (LCA) approach. This study was based on the cradle-to-gate approach which begins with the pre-nursery stage and progresses toward the main nursery before transplanting seedlings into the plantation site. Data or life cycle inventory (LCI) of seedling production were collected through questionnaire surveys and personal meetings with forest nurseries managers and workers regarding consumption of different inputs such as electricity, diesel, fertilizers, herbicides, and polyethylene bags, organic manure, and water consumption. The SimaPro software version 8.5 and the CML2000 v2.05 environmental model was applied to perform life cycle impact assessment (LCIA) for a single seedling production in forest nurseries in the study area. In line with the objectives of the study, primary data regarding inputs and outputs of the nurseries were collected from 35 nurseries in the study area by using a random questionnaire method. In addition, secondary data were taken from online databases such as Eco-invent v.3.2 CORRIM and peer-reviewed published literature. For this study, a functional unit of a single seedling was considered. Production weighted average data were modeled in the latest environmental modeling software i.e., SimaPro v.8.5 for ten US-EPA most wanted environmental impacts, such as global warming potential (GWP), abiotic depletion (AD), eutrophication potential (EP), acidification potential (AP), freshwater aquatic eco-toxicity (FAE), marine water eco-toxicity (MWE), terrestrial eco-toxicity (TE), ozone layer depletion (OLD), photochemical oxidation (PO), and human toxicity (HT). The results showed that the highest environmental impact posed by a single seedling was marine aquatic eco-toxicity (11.31360 kg 1,4-DB eq), followed by global warming potential (0.02945 kg CO2 eq) and (0.01227 kg 1,4-DB eq) human toxicity. The primary reason for these environmental burdens was the use of synthetic fertilizers in forest nurseries and the consumption of fossil fuels in nursery mechanization and transportation activities. The total cumulative energy demand for a single seedling was (0.800 MJ) with more than 90% contribution from fossil fuel energy resources such as petrol and diesel. It is therefore highly recommended to use renewable energy resources and organic fertilizers instead of chemical fertilizers in forest nurseries to avoid and minimize greenhouse gas emissions (GHS) and other toxic emissions in the study area.

Abstract Assessing the impacts caused by fisheries requires long-term data series and continuous landing monitoring, which are still scarce in several low and middle-income countries. Alternative approaches, such as fishers’ local ecological knowledge (LEK) have been employed to assess the history of marine resources and overcome the challenges of missing data. We documented temporal changes over the last 60 years in small-scale fisheries in Arraial do Cabo, Brazil. Interviews with 155 fishers revealed the capture of six shark species (one genus), all under extinction risk according to the global and the national Red Lists. Among these, Carcharhinus brevipinna, Carcharhinus plumbeus, and Isurus oxyrinchus are commercially important. While LEK suggests an increase in fishing efforts, with new fishing grounds emerging after 2006, the number of individuals caught has decreased over time. Historical shark exploitation has led to substantial declines in the catches of C. plumbeus and C. brevipinna, which have rare occurrences in the region. Although landing data are critical information for building local fisheries management plans and setting conservation strategies, monitoring in the region is discontinuous and should be prioritized by public policies. longterm long term middleincome middle income countries approaches (LEK 6 smallscale small scale Cabo Brazil 15 one genus, genus , genus) Lists these brevipinna important efforts 2006 time C strategies policies 1 200 20 2

Resumo Avaliar os impactos causados pela pesca requer dados de longo prazo e monitoramento contínuo das capturas, os quais ainda são escassos em vários países de baixa e média renda. Abordagens alternativas, como o conhecimento ecológico local dos pescadores (CEL), têm sido utilizadas para avaliar a história dos recursos marinhos e superar os desafios da ausência de dados. Documentamos mudanças temporais ao longo dos últimos 60 anos na pesca artesanal em Arraial do Cabo, Brasil. Entrevistas com 155 pescadores revelaram a captura de seis espécies de tubarões e um gênero, todas em risco de extinção de acordo com as Listas Vermelhas global e nacional. Entre essas espécies, Carcharhinus brevipinna, Carcharhinus plumbeus e Isurus oxyrinchus são comercialmente importantes. Embora o CEL tenha revelado um aumento nos esforços de pesca, com novos locais de pesca surgindo após 2006, o número de indivíduos capturados diminuiu ao longo do tempo. A exploração histórica de tubarões levou a declínios substanciais nas capturas de C. plumbeus e C. brevipinna, os quais possuem ocorrências raras na região. Embora os dados de desembarque sejam informações críticas para elaborar planos de gestão pesqueira local e estabelecer estratégias de conservação, o monitoramento na região é descontínuo e deveria ser priorizado por políticas públicas. renda alternativas CEL, , (CEL) 6 Cabo Brasil 15 gênero nacional brevipinna importantes 2006 tempo C conservação públicas (CEL 1 200 20 2

Abstract Bioseston is a heterogeneous assemblage of bacterioplankton, phytoplankton, zooplankton, and planktonic debris. A detailed knowledge of biosestons is essential for understanding the dynamics of trophic flows in marine ecosystems. The distributional features of seston biomass in plankton (micro- and mesoplankton) in the Southwest Atlantic Ocean (Rio de Janeiro State, Brazil) were analyzed using stratified samples gathered to a depth of 2,400 m during night time. The horizontal pattern of biomass distribution was analyzed vis-a-vis station depth during both wet and dry periods, with higher values recorded in the continental shelf than in the slope, confirming the terrestrial contribution of nutrient sources to the marine environment. This horizontal variation reinforces the occurrence of seasonal vortices in Cabo Frio and Cabo de São Tomé on the central coast of Brazil. Environmental variables reflect the hydrological signatures of the water masses along the Brazilian coast. The largest seston biomass was related to high temperatures, salinities, and low inorganic nutrient concentrations in tropical and South Atlantic central waters. The observed distribution patterns suggest that seston biomass in plankton in the region may be structured based on partitioned horizontal and vertical habitats and food resources. bacterioplankton phytoplankton zooplankton debris ecosystems micro (micro mesoplankton Rio State Brazil 2400 2 400 2,40 time visavis vis periods slope environment temperatures salinities waters resources 240 40 2,4 24 4 2,

Pentecostal ecotheology has been explored as the theology that can go beyond the anthropocentric focus of salvation towards the salvation of the non-human. This aspect of Pentecostal ecotheology has been explored by previous studies; however, the research gap exists in applying the same to sustainable development goals (SDGs). This article uses the pneumatological imagination as a theoretical framework to apply Pentecostal ecotheology to SDGs. The article argues that a pneumatological imagination is relevant in addressing the SDGs on hunger and agriculture (SDG2), water resources (SDG6), energy (SDG7), climate change (SDG13), conservation and sustainable management of marine resources (SDG14) and sustainability of terrestrial ecosystems (SDG15). The research findings are as follows: the pneumatological imagination can broaden the eschatological message to encompass social justice, political change and ecological repentance, beyond conventional evangelism. The pneumatological imagination envisions practical ways to engage in and contribute to the triune God's redemptive renewal of the world. The pneumatological imagination elevates individuals whose voices have been historically and traditionally marginalised because of gender, power dynamics or socioeconomic class. The pneumatological imagination aspires to provide a universal panorama and an inclusive capacity that envisions the salvation of everyone. The article is a literature review and data were analysed using the different themes of the United Nations' SDGs. INTRADISCIPLINARY AND/OR INTERDISCIPLINARY IMPLICATIONS: This article explores the relationship between theology and development studies by proposing a pneumatic Pentecostal ecotheology in the fulfilment of the SDGs of the United Nations

Resumen: La explotación de los recursos costero-marinos en nuestras costas ha ocurrido desde hace unos 12 000 años; esta actividad ha sido intensa y con menosprecio por el estado del recurso que se explota; como consecuencia, muchos de los recursos han colapsado a través de los siglos: las perlas, el carey, la madreperla, las tortugas, las chuchecas y muchas otras especies han dejado de ser comercialmente viables. Actualmente, los recursos pesqueros, que antes se creían inagotables, también muestran señales inequívocas de sobreexplotación. Lejos de haber mejorado nuestra relación con los recursos marinos ha empeorado; el aumento de la explotación, combinada con la contaminación y el calentamiento de nuestros mares, los ha deteriorado. Los imprescindibles análisis de biomasa y estado de las poblaciones explotadas siguieron sin realizarse, aún después de la fundación del INCOPESCA en 1994. Los desembarcos totales, entre 2000 y 2015, disminuyeron en un 45 % y la flota artesanal ha sido la más golpeada. Las embarcaciones pesqueras han pasado de 5 000 en el 2010 a menos de 2 000 cuatro años después y el número de empleos en el sector ha disminuido en un 50 %. Es urgente que tengamos una institucionalidad capaz de generar información que permita determinar el nivel y la forma de explotación adecuados. Este manejo debe ser independiente de intereses económicos y políticos y debe venir acompañado de una administración eficiente y efectiva, así como de un control y vigilancia estrictos de la actividad.

Abstract: The exploitation of coastal-marine resources has occurred in our coasts since about 12 000 years ago. This activity has been intense and careless regarding to the well-being of the resource being exploited. Consequently, many of the resources have collapsed throughout the centuries. Pearls, tortoiseshell, mother-of-pearl, turtles, mangrove-cockle, and many other species have stopped being commercially viable. Presently, fisheries, formerly believed inexhaustible, also show unequivocal signs of overexploitation. Far from improving, our relationship with marine resources has exacerbated. The exploitation increment, combined with contamination and ocean warming, have deteriorated these resources. Essential biomass and population status analyses continue to be neglected, even after the founding of INCOPESCA in 1994. Total ship landings, between 2000-2015 have decreased 45 % impacting particularly the artisanal fleet. The number of fishing vessels have gone from 5 000 in 2010 to less than 2 000 four years later and the number of jobs in the sector has decreased by 50 %. It is urgent to have an institution able to generate information that allow us to determine the level and manner of this exploitation. Such management needs to be independent of economic and political interests and should be coupled with an efficient and effective administration, together with strict control and surveillance of this activity.

Abstract Introduction: Until today, the fishing effort by foreign fleets in the Costa Rican Pacific has not been analyzed. Objective: To determine the spatial distribution of the fishing effort of those fleets, variables that shape that distribution, and if they interact with management figures and highly fragile ecosystems. Methods: Using fishing effort data from 2012 to 2020, obtained from Global Fishing Watch, an Index of Fishing Effort (IEP) was calculated to apply geospatial and multivariate statistics, as well as multiple regression models. A grid with 55 905 cells of 0.10 degrees was used to apply Hot Spot Analysis, and another grid with 24 176 cell-year-month analysis units of 0.25 degrees was used to apply a Linear Regression Model. Results: The data reveals the fishing activity of international fleets associated with four types of fishing gear, and a wide coverage of a high IEP by two fleets throughout the nine years analyzed. The IEP is primarily associated with location and varies by month and year. There is also relative evidence that its influenced by the concentration of oxygen and nitrates. Conclusions: International fleets come into direct conflict with officially defined zones for national fleets and disrespect protected oceanic areas and a declared non-fishing zone to protect marine resources in the Costa Rican Pacific. Their activities in the Dome may affect a national yellowfin tuna fishery.

Abstract This work discusses development strategies in peripheral contexts, starting from questioning the relationship between new technologies, territorial strategies and the exploitation of primary resources as part of the national productive diversification agenda. Within this framework, aquaculture will be analyzed as an exponent that incorporates technological innovations to reduce the impact of the exploitation of natural resources on the environment. Specifically, we board the case of the potential implementation of a multitrophic marine farm in the Province of Tierra del Fuego, Antartic and South Atlantic Islands, Argentina from the analysis of primary and secondary sources. As a result, dynamics associated with the incorporation of technological innovations that respond to territorial conditioning are noticed, and a series of categories are proposed to study and evaluate the feasibility and virtuosity of similar cases.

Resumen Este trabajo busca discutir las estrategias de desarrollo en contextos periféricos, a partir de interpelar la relación entre las nuevas tecnologías, las estrategias territoriales y la explotación de los recursos primarios como parte de la agenda de diversificación productiva nacional. En ese marco, se analizará la acuicultura como un exponente que incorpora innovaciones tecnológicas para reducir el impacto de la explotación de recursos naturales sobre el ambiente. Específicamente, se aborda el caso de la potencial implementación de una granja marina multitrófica en la provincia de Tierra del Fuego, Antártida e Islas del Atlántico Sur, Argentina, a partir del análisis de fuentes primarias y secundarias. Como resultado, se advierten dinámicas asociadas a la incorporación de innovaciones tecnológicas que responden a condicionamientos territoriales, y se proponen una serie de categorías para estudiar y evaluar la factibilidad y virtuosismo de casos similares.

Given a growing global population and shift to embrace the blue economy, a need for marine spatial planning (MSP) has emerged in South Africa to sustainably resolve the rising conflicts over the use of marine and seabed resources and services. A well-developed marine spatial plan yields numerous ecological, social and economic benefits. These are achieved through mediating between spatially conflicting economic drivers' interests (e.g. commercial fishing, tourism, mining), preventing their activities from compromising thresholds of an environment's sustainability. Within the MSP framework, high-resolution geospatial datasets are required to document and describe the seabed in the highest possible detail. At any scale, integrated analysis of seabed geomorphology and habitats is anticipated to greatly improve the understanding of ecosystem functioning from a multidisciplinary perspective, whilst improving MSP procedures and management of marine space. South Africa is the first of few African countries to have an approved and implemented MSP framework, but is still somewhat behind globally in implementing large-scale regional hydroacoustic surveys to cover the country's vast offshore territory. The deficiency of hydroacoustic surveys is perhaps due to a relative lack of funds and poor communication about the value of multibeam echo-sounder (MBES) derived data, whilst marine geoscience remains a scarce skill in the country. This review paper presents a geological perspective of MSP and explores (1) the value that seabed mapping offers MSP specifically and (2) the need to increase seabed mapping with MBES, using a recently initiated project from the South African east coast as a case study. SIGNIFICANCE: The collected MBES data (our case study) provides unprecedented seabed detail of the complex reef habitat and adjacent areas within specific management zones of the uThukela Banks Marine Protected Area. We reveal seabed features and their spatial distribution at a scale not possible using earlier (singlebeam) seabed mapping techniques. These high-resolution data will enable a better understanding of east coast marine habitats whilst contributing to improved spatial management of areas within and around the uThukela Banks Marine Protected Area.
