“…As emphasized by Ferreira and Lacerda (2016a), in order to promote mangrove conservation, besides government enforcement of the protection legislation, people need to be aware of the goods and services provided by mangroves. Unfortunately, population awareness usually only arises after the consequences of mangrove degradation (Barbier, 2006), so providing people with information about similar cases and the consequences of mangrove degradation elsewhere through experience exchange could be a shortcut to avoid human-promoted mangrove degradation by lack of knowledge.…”

“…Native populations, especially those directly dependent on mangrove goods and services, as well as other societal sectors, need to be integrated through community-based management (Ferreira and Lacerda, 2016a). In addition, when considering the effectiveness of protected areas, besides creating more and larger reserves, it is important to concomitantly invest in education, economic incentives, and community-based enforcement (Rife et al, 2013).…”

“…Partnerships with mangrove research groups need to be created and strengthened (Ferreira and Lacerda, 2016a). Scientific research can contribute, for example, with the development of methods to incorporate local ecological knowledge, through bottom-up social studies that shed light on how to apply this knowledge to the development of conservation strategies for mangroves.…”

“…This is especially relevant to assess monetary and non-monetary values of ecosystem goods and services. With such a valuation at the local level, policy makers can be made aware that the profit coming from the shrimp market, for example, is considerably smaller than the environmental damage caused, as exposed in the case of some intensive shrimp farms in NE Brazil (Ferreira and Lacerda, 2016a). {One exception could be, for example, organic farms in NE Brazil and traditional "tambacs" in Asia, which may have a mutual benefit for adjacent mangrove forests (Lacerda et al, 2002).}…”

“…Following a global pattern (Walters et al, 2008), the values associated with Brazilian mangrove ecosystems are not taken into account by policy makers, when, for example, shrimp farming is considered more valuable than mangrove preservation. Despite pressure and consequent damages over mangroves, little is known about their unique value in terms of ecosystem services, since local variation can be high due to site specificities along the Brazilian coast (Souza and Ramos e Silva, 2010;Estrada et al, 2015;Ferreira and Lacerda, 2016a). But even these few accurate studies are not taken into consideration by decision makers or environmental authorities.…”

Systematic Planning and Ecosystem-Based Management as Strategies to Reconcile Mangrove Conservation with Resource Use

About 120 million people worldwide live within 10 km of large mangrove forests, and many of them directly depend on the goods and services provided by these ecosystems. However, it remains unclear how to synchronize ecological definitions and legal conservation strategies regarding mangroves, especially in developing countries, such as Brazil. The influence of human populations' socio-economic context in mangrove conservation policies, as well associated challenges in incorporating this influence, are underestimated or, often, largely ignored. Considering the recent threats emerging from changes in legislation and the lack of spatial and social-ecological integrated data to plan mangrove conservation in Brazil, this paper aims to answer the following questions: (1) What suitable measures could managers and other decision makers adopt for efficient mangrove conservation planning?; (2) What are the site-specific, social-ecological aspects that need to be taken into account when deciding on conservation and management strategies?; and (3) How could science contribute to the development of these measures? In order to achieve an ecosystem-based management approach, mangrove ecosystems should not be divided into sub-systems, but instead treated as an integrated system. Furthermore, interconnections with other coastal ecosystems must be assessed and taken into account. This is crucial for effective systematic conservation planning. Also, most of the particular social-ecological aspects in the different types of mangrove ecosystems along the Brazilian coast, and how those differences might be considered while planning for conservation, remain poorly understood. Based on similar drivers of change, geological features, and likely impacts of climate change, a macro-unit approach is proposed to group mangrove systems along the Brazilian coast and guide national policies. This paper draws parallels with management approaches worldwide to find common points and hence lessons to be applied in other regional realms. It considers the issues of legal vulnerability and needs for social-ecological data on mangroves, contributing toward systematic conservation planning and ecosystem-based management for these ecosystems.

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.
