Abstract

Along the Brazilian shoreline, on the northern coast of Rio Grande do Norte State Brazil) are located the largest solar saltworks of the country. The present research aims to evaluate the sustainability of the consumption of estuarine water and the area required for salt production in Brazilian solar saltworks situated along the estuary of the River Apodi-Mossoro (Rio Grande do Norte State). The analysis of the total area of production values, water volume estuary used and annual salt production was carried out, relating to the area required for this production in a solar saltwork located upstream (lower estuary) and another downstream (high estuary) in this estuary. That due to high salinity values of estuarine water upstream, the downstream saltworks require a production area three times larger than those located upstream, which obtain a production only twice superior. It was verified that the saltworks located downstream utilize the largest area and require more water volume for salt production.

Highlights

The largest saltworks of Brazil are located along the Brazilian shoreline, on the northern coast of Rio Grande do Norte State (Brazil), mainly on the margins of the estuaries (DE MEDEIROS ROCHA et al, 2009; COSTA, 2010)
Considering that environmental conditions directly influence the production process of salting activity (DE MEDEIROS ROCHA e CAMARA, 1993; DAVIS, 2000; SOUTO et al, 2000a,b; MOOSVI, 2006; KOROVESSIS E LEKKAS, 2009), there is a lack of environmental indicators that allow identifying which environmental characteristics of a given area may influence the sustainability of sea salt production in solar saltworks (DAVIS, 2009)
The present study aimed to evaluate the sustainability of estuarine water consumption and land use for sea salt production in saltworks located along the estuary of the River Apodi-Mossoró, on the northern coast of Rio Grande do Norte State (Brazil)

Introduction

The largest saltworks of Brazil are located along the Brazilian shoreline, on the northern coast of Rio Grande do Norte State (Brazil), mainly on the margins of the estuaries (DE MEDEIROS ROCHA et al, 2009; COSTA, 2010). Considering that environmental conditions directly influence the production process of salting activity (DE MEDEIROS ROCHA e CAMARA, 1993; DAVIS, 2000; SOUTO et al, 2000a,b; MOOSVI, 2006; KOROVESSIS E LEKKAS, 2009), there is a lack of environmental indicators that allow identifying which environmental characteristics of a given area may influence the sustainability of sea salt production in solar saltworks (DAVIS, 2009) In this way, the present study aimed to evaluate the sustainability of estuarine water consumption and land use for sea salt production in saltworks located along the estuary of the River Apodi-Mossoró, on the northern coast of Rio Grande do Norte State (Brazil)
