“…Such research is particularly important given the disagreement in the literature as to whether mangrove systems truly exhibit catastrophic shifts within an alternative stable state framework enabled by ecogeomorphological ecosystem engineering (e.g., perhaps as in [201,241]), or rather just continuous phase shifts within the framework of succession (e.g., [233,242]). …”

Multiple Stable States and Catastrophic Shifts in Coastal Wetlands: Progress, Challenges, and Opportunities in Validating Theory Using Remote Sensing and Other Methods

et al. 2015

Multiple stable states are established in coastal tidal wetlands (marshes, mangroves, deltas, seagrasses) by ecological, hydrological, and geomorphological feedbacks. Catastrophic shifts between states can be induced by gradual environmental change or by disturbance events. These feedbacks and outcomes are key to the sustainability and resilience of vegetated coastlines, especially as modulated by human activity, sea level rise, and climate change. Whereas multiple stable state theory has been invoked to model salt marsh responses to sediment supply and sea level change, there has been comparatively little empirical verification of the theory for salt marshes or other coastal wetlands. Especially lacking is long-term evidence documenting if or how stable states are established and maintained at ecosystem scales. Laboratory and field-plot studies are informative, but of necessarily limited spatial and temporal scope. For the purposes of long-term, coastal-scale monitoring, remote sensing is the best viable option. This review summarizes the above topics and highlights the emerging promise and challenges of using remote sensing-based analyses to validate coastal OPEN ACCESS Remote Sens. 2015, 7 10185 wetland dynamic state theories. This significant opportunity is further framed by a proposed list of scientific advances needed to more thoroughly develop the field.

“…Environmental degradation of mangroves and coastal pollution is of considerable concern along the Brazilian coast (Souza ; Rovai et al . ). Losses of South American oyster beds have been inferior to 50% but, despite a relatively better status in relation to other continents, there is little or no regular monitoring (Carranza et al .…”

“…Despite growth in Brazilian oyster culture, mentioned above, there are a number of weaknesses in the sector, which is in need of strategic planning, with a view to avoiding possible conflicts and/or the elimination of small-scale units should operations on a larger, more industrial scale come into effect (Ostrensky et al 2008). Environmental degradation of mangroves and coastal pollution is of considerable concern along the Brazilian coast (Souza 2009;Rovai et al 2012). Losses of South American oyster beds have been inferior to 50% but, despite a relatively better status in relation to other continents, there is little or no regular monitoring (Carranza et al 2009;Beck et al 2011).…”

Oyster culture activity along the eastern Amazon mangrove coast in Pará state, Brazil, was evaluated using socio‐economic data to support its management and future development. Between 2013 and 2014, surveys were carried out in the region's seven oyster culture associations through interviews with the president of each association as well as with 56 members (72% of the total). Further data up to 2016 were obtained from annual reports of the Serviço Brasileiro de Apoio às Micro e Pequenas Empresas in Pará and the Instituto Brasileiro de Geografia e Estatística. Two associations stand out from the rest due to their larger on‐growing areas and total production in 2013. However, smaller associations are more efficient with higher production per unit area. Currently, oyster culture in Pará provides an alternative source of income for 80 families, where total production has increased from 8.25 tons in 2013 to 41.8 tons in 2016. Although associations have grown in number since 2006, along with increased capacity and production due to government assistance, in comparison with other regions of Brazil, they need to be better organized internally, including regular monitoring of growth, production and environmental variables, development of depuration facilities and improved distribution and presentation of products. Diversification of seed supply among different locations is desirable. There should also be less dependence on public funding and more partnerships with private enterprise, as well as active coparticipation in the development of legislation and public policies regulating both oyster culture and protection of natural oyster beds.

“…the development of impervious surfaces and groundwater extraction) that alter sediment supply (Gilman, Ellison, Duke, & Field, 2008) or by establishing salt ponds or shrimp farming ponds at the landward fringe of mangroves, which squeezes mangroves between a rising sea level and areas artificially relocated outside the area of tidal influence (Ferreira & Lacerda, 2016;Godoy & Lacerda, 2015). (Elster, 2000;Field, 1996;Fonseca & Drummond, 2003;Menezes, Poffo, & Eysink, 1998;Menezes, Schaeffer-Novelli, Poffo, & Eysink, 2005;Paludo & Klonowski, 1999;Rovai, 2012;Rovai et al, 2012), but only a small number of studies have monitored tree development after planting, for example, in terms of biomass and carbon capture (DelVecchia et al, 2014;Ferreira, Ganade, & Attayde, 2015;Kamali & Hashim, 2011;Kauffman, Heider, Norfolk, & Payton, 2014;Rovai, 2012) to provide comparable data. Rovai (2012) estimates that 2,617 ha (26,17 km 2 ) of mangroves were planted between 1994 and 2010 in Brazil; that is, close to 25% of the estimated increase in mangrove areas .…”

This study assesses the evolution of major anthropogenic drivers of environmental impacts on Neotropical mangroves, the changes in the environmental pressures acting upon them, and the respective societal responses during the past 40 years. It reviews the impacts of new drivers, in particular those resulting from global climate change and the expansion in aquaculture and the effectiveness of local societal responses aimed at addressing them. Adaptation and mitigation actions are proposed to cope with the impacts and their socio‐economic consequences for Latin America and Caribbean mangroves. By comparing the situation in Latin America and the Caribbean with other regions, the knowledge gaps and priority research needs are discussed to support delineating a preliminary unifying framework to address the environmental pressures affecting mangroves. This scenario necessarily includes the interaction of climate change with human interventions and their effects on ecosystem goods and services, as well as their respective adaptation and management options. Results show that drivers of environmental impacts have changed in the past 40 years, reducing the effectiveness of some important societal responses towards conservation and sustainable management with a great potential to increase rates of mangrove deforestation and conversion to human uses. Although efforts in conservation and restoration have contributed to decreasing pressure on these ecosystems, the coupling of old drivers, such as damming, with climate change, and the appearance of new drivers in the region, such as shrimp aquaculture, may eclipse the gains made through these conservation efforts. Despite the negative trend, we discuss some successful efforts to curb negative impacts of human activities on mangroves. We also recommend regional assessments based on primary sources in the representative mangrove‐bearing countries throughout the continent to allow the upscaling of their experiences towards a regional response to the challenges facing Neotropical mangrove conservation and sustainable use.
