“…This shift is attributed to climate, river discharge and RSL changes (Behling et al, 2004;Cohen et al, 2005aCohen et al, , 2008Cohen et al, , 2009França et al, 2012;Lara and Cohen, 2009;Smith et al, 2011Smith et al, , 2012. However, in southeastern Brazil, the mangrove dynamics are mainly related to RSL changes (Buso Junior, 2010;Buso Junior et al, in press) and sediment transport (Amaral et al, 2006).…”

“…Geographical setting The ADE is the mouth of the world's largest river basin, with a drainage area of about 6 million km 2 (Cohen et al 2008). This tropical delta is tide-dominated (Hori and Saito 2007), and characterized by a series of distributaries and islands between the states of Amapá and Pará, in the northern region of Brazil.…”

An assessment of urban vulnerability in the Amazon Delta and Estuary: a multi-criterion index of flood exposure, socio-economic conditions and infrastructure

et al. 2016

The Amazon Delta and Estuary (ADE) is a region of continental and global ecological importance. Controversy, many of the basic infrastructure and services essential for quality of life and sustainable development of this delta are absent. Using a conceptual model to define socio-economic vulnerability in the urban ADE, a thorough assessment of indicators including sanitation services, housing conditions, household income, population, flood risk and unplanned settlements was conducted in 41 cities at the census sector scale (n = 2938). A multi criterion index was applied to classify urban vulnerability from three dimensions: flood exposure, socio-economic sensitivity and infrastructure. This is the first study to examine urban vulnerability within and between urban areas of the ADE. Results indicated that most of the urban sectors of the ADE are exposed to potential risks due to a combination of flood hazards, poverty and basic structural deficiencies such as insufficient drinking water or inadequate waste water collection, with several sectors being afflicted by similar problems. The assessment of vulnerability indicates that 60-90 % of the urban population live in conditions of moderate to high degree of vulnerability. The ADE cities presented a pattern where vulnerability increases from city center to their newly developed urban areas. Inadequate planning coupled with rapid urbanization has contributed to the development of unplanned settlements in almost half of the urban sectors of the ADE. Combined, these factors contribute to widespread socio-economic vulnerability along the urban spaces of the ADE, increasing exposure to health risks and more frequent seasonal and stochastic events such as storm surges and high flooding levels.

“…These traits, summed up with strong human-use pressures (Godoy and Lacerda, 2015), might hinder mangrove survival in the face of climate change. On the other hand, mangrove areas have the chance to expand in the northern part of the coastline, following predictions related to sea-level rise, because here mangroves find landward areas for expansion, such as in the Amazon estuary (Cohen and Lara, 2003;Cohen et al, 2008;Ward et al, 2016). Along the eastern and southeastern coasts, estuaries and coastlines have suffered severe damage (Magris and Barreto, 2010;Prates et al, 2012).…”

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.
