: The present study aimed to evaluate the environmental perception of the users of two beaches of Niterói - RJ: Itaipu and Itacoatiara, and to describe their socioeconomic profile, due to the presence of marine debris in coastal space. For this evaluation, a closed questionnaire was applied to a total of 200 people (100 in each beach). Based on the answers, it was possible to observe the different environmental perceptions of the interviewees regarding the possible alternatives provided. Most of the interviewees, on both beaches, had higher education, were between 18 and 30 years of age and had a monthly income of 2 to 5 minimum wages. The results show that although beach users have a perception about the problem of marine debris in coastal environments, the presence of these in the sand contradicts this fact. In this way, it is evident that a critical perspective on environmental education, together with awareness campaigns, should be disseminated to surrounding communities, in order to support discussions about the interventions required for participatory and effective environmental management.

: The influence of small human settlements on the distribution of marine litter is not well known. We investigated the potential contribution of such settlements in the distribution of the abundance and richness of macro litter (>1 cm) along a beach stretch in the northeast coast of Brazil coast. In order to investigate if the garbage would increase near coastal villages, we collected stranded marine litter in 45 transects, along 8.1 km of the beach stretch, including the ocean front of two small human settlements (Siribinha and Poças). We used a generalized additive model (GAM) and found greater waste richness in Siribinha and between Siribinha and Poças. No clear variation trend was evidenced in the amount of marine litter along the sampling sites. This indicate an unsystematic pattern of the distribution of litter near small villages, opposing to patterns observed in large urban centers. Therefore, litter produced far away may be a worse problem, then local litter, in remote coastal areas.

The study area lies in the lower estuary of Lagoa dos Patos in the city of Rio Grande (Lat/Long: 32°02’16.39”S/52°06’28.41’’W), Rio Grande do Sul state, Brazil, comprising a total area of approximately 280,000 hectares (ha). To select areas suitable for marine shrimp farming, data processing and digital modeling were conducted with the Idrisi Andes Edition® GIS software using freely available images. Additionally, the most commonly used criteria, socioeconomic factors, infrastructure and logistics, soil, climate, topography, and water availability, were used. To improve upon the obtained results from a classification based exclusively on the distinction between restricted and suitable areas for aquaculture, a suitability score for each criterion analyzed was created, and distances from suitable sites were measured. According to the suitability rating (prioritized from 1 to 4), 2,100 ha (24.01% of the area) were considered suitable with excellent conditions; 3,100 ha (34.80%) were considered good; 3,600 ha (40.37%) were marginally suitable; and, finally, a small fraction of 70 ha (0.82%), was considered acceptable but not recommended. This study has demonstrated the potential of GIS to support the selection of areas suitable for marine shrimp farming.

This article describes changes in the shoreline near the port complex at Maranhão, Brazil, and adjacent areas. The main objective was to evaluate the morphological changes in the study area during recent decades based on satellite remote sensing image analysis by comparing a series of eight images obtained with different sensors (Landsat, Quickbird, Geoeye, Ikonos, and Worldview 2 and 3) in the vicinity of an industrial harbor area. The shoreline was characterized by digitization and vectorization using each image, and the statistic spatial changes in the shoreline were quantified using the Digital Shoreline Analysis System. In addition, time change detection analyses were conducted in specific areas in order to establish correlations between the erosion/deposition areas with changes in vegetation and the land-cover dynamics. Throughout most of the area, the shoreline tended to remain stable during the study period. However, four specific areas exhibited variability at localized points on the shoreline, particularly areas near the port region and those adjacent to estuarine channels evidencing that the port complex has a direct influence on the shoreline behavior in a relatively stable area.

Knowing the behavior of population dynamics in coastal areas is an essential element for its proper management. Using historical information, in this paper, estimates of the total population in the coastal states of Mexico are made up to the year 2050 with an analysis of the population dynamics in the coastal municipalities for the years 2000, 2005, 2010 and 2015. According to the latest census, Mexican total population reached 102 million people in 2015 with 55,3 million (46 %) living in coastal states. In the 17 coastal states of Mexico, a total of 158 municipalities with direct access to the sea were identified in 2015, in which 18,9 million inhabitants lived. During the period 2010 to 2015 the highest relative population growth rate at state level was observed in Quintana Roo (13.3%). In 2015, the coastal municipality of Tijuana in Baja California State was the most populated in the coastal zone with 1,6 million inhabitants. In 15 years (2000-2015), 4 municipalities have increased their population by 100% or more, prevailing in these localities activities related with international tourism. The coastal population growth rate for the period 2010-2015 showed a deceleration compared to 2005-2010. By the year 2050, a population of 65 million people living in the coastal states of Mexico was estimated. The results presented in this study give elements to the decision makers to strengthen the planning and management processes of the Mexican coastal zone in the medium term.

Field data based information on the coastal sediment dynamics becomes even more relevant for coastal managers in the present context of climate changes. Due to the sea level rise and the increase of frequency and intensity of coastal storms, coastal managers need to implement effective and efficient solutions for increasing coastal resilience, namely through reprofiling the beach for restoring the sediment balance and providing space for the beach natural dynamics. The study characterises and quantifies the morphological changes in an Atlantic urban sandy beach under extreme wave energy and sea level conditions. The erosion of the foreshore and backshore of this particular beach was characterised as function of the intensity and duration of the hydrodynamic forcing parameters (waves and sea level). This 24-hour duration storm event, which delivered to the beach a total energy of 1.7x109 J, caused the seaward displacement by the undertow current of approximately 3x103 m3 of median well sorted sand from the beach foreshore and backshore.
