“…The intense use of natural resources threatens the existence of mangrove ecosystems, as many of these coastal areas have become large economic and population centers (Schaeffer-Novelli et al 2000, FAO 2007, Jablonski & Filet 2008. The main potential impact-generating vectors include the barring of rivers, extraction of fauna, aquaculture, production of salt and urbanization which results in pressure being put on the balance of sediments and water chemistry in estuaries and the flowing of nutrients and polluting material (Ellison & Farnsworth 1996, 2001, Fondo & Martens 1998, Alongi 2002, Spalding et al 2010.…”

Resumen.-Se caracterizó la estructura de la vegetación de los bosques de manglares en 9 estuarios en el estado de Ceará, nordeste de Brasil, con el propósito de compararlos y lograr concesión de subvenciones para su conservación. Se utilizó el método de los cuadrados múltiples, con 3 transectos de 5 cuadrantes en cada sitio. Se obtuvieron valores de diámetro y área basal de los árboles, la dominancia, la densidad del tronco y la frecuencia relativa de cada especie, además de las variables para el análisis de los sedimentos. Los resultados de los parámetros estructurales obtenidos mostraron diferencias entre los bosques de la muestra, de forma que los niveles más altos de densidad se hallaron en los ríos Acaraú, Ceará y Guriú. El rio Guriú además presentó los menores valores de altura, área basal y Diámetro a la altura del pecho (DAP). El análisis de agrupamiento de especies indica una separación de 3 grupos: 1) Cocó y Ceará, 2) Acaraú, Jaguaribe y Pacoti, y 3) Aracatimirim y Guriú. Los bosques de manglares en Curú y Barra Grande no conformaron ningún grupo con los anteriores. El Análisis de Componentes Principales (ACP) indicó que los sedimentos recogidos en los estuarios presentan una composición distinta. Las diferencias entre los sitios se deben tener en cuenta cuando se proponga la administración, ya que cada manglar exige estrategias diferentes para su mantenimiento.Palabras clave: Ceará, estructura de la planta, sedimento, vegetaciónAbstract.-The aim of this study was the characterization of mangrove forests in 9 estuaries in the state of Ceará, northeastern Brazil, with the purpose of comparing them and providing subsidies for their conservation. We used the method of multiple squares, having 3 transects of 5 quadrats at each site. We obtained values for the diameter and basal area of the individuals, dominance, trunk density and relative frequency per species, as well as variables for the analysis of sediment. The results obtained regarding structural parameters showed differences among the sampled forests, where the highest density levels were found in the Acaraú, Ceará and Guriú rivers. The Guriú River also presented the smallest values for height, Diameter at Breast Height (DBH) and basal area. The grouping analysis indicates 3 groups of forests: 1) Cocó and Ceará; 2) Acaraú, Jaguaribe and Pacoti, and 3) Aracatimirim and Guriú. The mangrove forests in Curú and Barra Grande were not grouped. The Principal Component Analysis (PCA) indicated that the sediments collected in the estuaries present a distinct texture composition. The differences between the areas must be taken into consideration when proposing management, as each mangrove demands different strategies for its maintenance.

“…Marine and coastal areas have been less studied than terrestrial habitats, have areas of difficult access and surveillance and threats to these ecosystems comprise those derived from activities in coastal and marine areas but also from activities in terrestrial areas, even distant ones (ASMUS et al, 2006;CICIN-SAIN;KNECHT, 1998;HALPERN et al, 2008;JABLONSKI;FILET, 2008). Such threats have already compromised coastal and marine ecosystem (ELFES et al, 2014;HALPERN et al, 2012;MEA, 2005), and the need to promote coastal and marine sustainability has led to actions to enhance their sustainability.…”

“…There are many obstacles for social participation in management processes, such as coping with the lack of representativeness, overcoming language barriers, sharing knowledge and power among participants, and empowering and engaging the individuals (ASMUS et al, 2006;BROWN;TOMPKINS;ADGER, 2002;DA FONSECA;BURSZTYN;ALLEN, 2012;JABLONSKI;FILET, 2008;KALIKOSKI;SEIXAS;ALMUDI, 2009;TRIMBLE;SEIXAS, 2014). Participating is more than the mere presence of people in decision making arenas, it is necessary to make them truly engage in the discussion and be part of the joint construction of public policies, otherwise participatory spaces may only serve to endorse the will of a dominant faction or reproduce social exclusions (ARAUJO; SEIXAS, 2012;BROWN;TOMPKINS;ADGER, 2002;MARTIN;LEMON, 2001).…”

“…The participatory management of such environments is conducted through management groups that depend highly on institutional articulation since the management is a shared competence among many multi-scale organizations (DIEGUES, 2001;GERHARDINGER et al, 2011;JABLONSKI;FILET, 2008;JENTOFT, 2000). Local stakeholders (the ones usually involved with the management boards) do not have all the power to promote legal enforcement and compliance of their propositions (LEACH;PELKEY, 2001;MOSTERT et al, 2007).…”

“…In some countries, the management of marine areas is a common competence among the federation/union, states and municipalities (JABLONSKI; FILET, 2008;JENTOFT, 2000). Additionally, marine activities (e.g., fishing, navigation, oil drilling) are under the authority of specific governmental organizations that must be included in the management process (JENTOFT, 2000).…”

This paper identifies opportunities from targeted and integrated sanitation action to achieve the Sustainable Development Goals (SDGs). This is contextualised to the case of Brazil through a systematic approach applied to the sanitation sector that considers the range of infrastructure, management services and people involved in different phases of the service chain, from municipal wastewater containment to safe disposal or re-use. Articulating the social, economic and environmental dimensions of sanitation, this study analyses their links with each of the 169 SDG targets. We demonstrate that 87 targets across 16 goals require action in Brazil's sanitation sector to achieve the SDGs. Furthermore, we identify synergies between sanitation and 124 targets in four domains: basic services for resilience building, equity and
