“…This region is characterized by extensive demographic voids (Fig 5), and only 8% of the population of Pará live in the coastal zone [70], whereas in other Brazilian regions, the coastal zone is inhabited by up to 40% of the population [71]. In the Amazon region, with the exception of the metropolitan areas (Belém and São Luís), the economies of the coastal microregions are based on traditional local subsistence activities, in particular, artisanal fisheries, and the exploitation of other mangrove resources [11, 32, 72]. In this scenario, paved roads are the principal drivers of mangrove land use on the Brazilian Amazon coast.…”

“…A delicate bias exists in this process, when the development of roads may result in social problems for traditional local communities. The mangrove of the Ajuruteua Peninsula, in Pará, is an important component of this process, with 80% of the natural resources extracted from this area being destined for regional markets [11]. This has a negative effect on the activities of the residents that harvest natural resources from local estuaries, by reducing the value of their labor in the productive chain, as well as transforming sustainable practices into the predatory exploitation of natural resources.…”

“…Mangroves also play a key role in human sustainability and livelihoods. The biodiversity of these forests is exploited by the human populations of tropical coastal-estuarine regions for their subsistence needs, including the harvesting of food and fuel wood, and the extraction of lumber for construction [11, 12]. The mangrove ecosystem is also among the world’s most dynamic and productive coastal environments [13], with a primary production equivalent to that of the tropical rainforest [14].…”

“…Its landscape is derived from the combination of a small number of species and the unique local climatic and edaphic conditions [12], including 7,210 km 2 of mangrove forest and a salt flat zone of 542 km 2 [56]. The mangroves of this region have enormous social and economic value for the local population, providing essential resources for the production of food and the generation of income, and guaranteeing the survival of the local communities [11,63].…”

The effect of anthropogenic drivers on spatial patterns of mangrove land use on the Amazon coast

Mangroves play an essential ecological role in the maintenance of the coastal zone and are extremely important for the socioeconomics of coastal communities. However, mangrove ecosystems are impacted by a range of anthropogenic pressures, and the loss of this habitat can be attributed primarily to the human occupation of the coastal zone. In the present study, we analyzed the spatial patterns of land use in the mangrove of the Brazilian Amazon coast, and evaluated the anthropogenic drivers of this impact, using a remote sensing approach. We mapped the road network using RapidEye images, and human settlements using global data. The results of these analyses indicate that the Brazilian Amazon coast has a low population density and low rates of anthropogenic impact in most of the coastal microregions investigated, factors that contribute to the maintenance and conservation of the region’s mangrove. The study also revealed that the paved road network is one of the principal drivers of land use in the mangrove, whereas other factors, such as population density, urban centers, and the number of settlements are much less important. While the region has 2024 km of paved highways, unpaved roads (17,496 km) facilitate access to the mangrove, with approximately 90% of anthropogenic impact being recorded within a 3 km radius of these roads. While the network of paved highways is relatively reduced in extension, preventive measures are urgently required to impede any major shift in the current scenario, caused by the expansion of major development programs. The results of the study indicate that biophysical, economic, and political factors may also contribute to the reduction, stability, and development of one of the world’s largest areas of mangrove forest.

“…In the case of mangroves, for example, "mangrove civilizations" (Diegues, 1995) practice artisanal fisheries (Diegues, 2008). These are usually the main socio-economic activity in these areas (Fernandes et al, 2018), such as the Amazon macrotidal mangrove coast (Souza Filho, 2005). This coast is one of the longest (Souza Filho, 2005) and most important protected mangrove regions on the planet (Hayashi et al, 2019) and its coastal-estuarine communities depend on the mangrove ecosystem services (Eyzaguirre and Fernandes, 2018;Fernandes et al, 2018).…”

Systematic Review of Spatial Planning and Marine Protected Areas: A Brazilian Perspective

et al. 2020

Marine protected areas (MPAs) are essential to human well-being and usually part of spatial planning processes for managing coastal and marine areas. In Brazil, national-level spatial planning processes are still incipient. This article offers a systematic review through a comparative meta-analysis of the literature on MPAs and spatial planning based on the following questions: (I) What topics are investigated in spatial planning in MPAs worldwide? and (II) What are the advances and trends of these topics in Brazilian MPAs? Specific goals of this study are (I) to identify studies on Brazil; and (II) to compare and contrast these with studies performed elsewhere. The PRISMA report was used to select literature, with a focus on three spatial contexts (I) outside Brazil, analyzing studies from other countries; (II) in Brazil; and (III) a case study in Brazil that focuses on a sustainable-use area in northeastern Pará. Studies outside Brazil showed three major groups of themes: (I) planning and tools; (II) stakeholders; and (III) the ecology of non-human species. For the Brazilian context, studies were grouped into five major themes: (I) small-scale fishing practices and conflicts; (II) participation in protected areas; (III) technical aspects of the planning process, (IV) zoning; and (V) mapping. The local case study investigates socio-cultural sustainability and tourism. All identified studies relate to use, but have a greater focus on conservation and, especially abroad, on species and ecosystems. There are few reviews or comparative studies that could help to draw parallels between the different spatial planning settings. We conclude that synthesis work on spatial management strategies worldwide is needed, including the elaboration of frameworks to develop measures to address the widespread lack of data and spatial planning expertise. Collaborative networks of researchers and practitioners are needed for this. The novelty in our study is that it examines MPAs and spatial planning research at three spatial contexts with innovative methodologies to represent the current state of the spatial planning discourse in coastal and marine conservation.
