“…Regarding the water and land use interest conflict in the LJRSB, a study using a GIS-based approach associated with participatory decision making and land suitability assessment could be conducted. For example, [57] performed a multi-criteria land suitability assessment, through spatial analysis based on four stakeholder sector visions: aquaculture, agriculture, cattle ranching, and conservation for a coastal area in Mexico; they found that for planning purposes, shrimp farming developments should be favored, and they highlighted that spatial analysis is fundamental in preventing the problems generated by shrimp farming activities.…”

Aquaculture is currently one of the fastest growing food production systems globally, and shrimp is considered one of the most highly valued products. Our study area is the lower Jaguaribe River sub-basin (LJRSB), located in the northeastern part of Ceará in Brazil. The aquaculture activity in this area began in the early 1990s and is currently one of the largest shrimp producers in Brazil. This study generated a spatial-temporal analysis of vegetation index and land use and land cover (LULC) using remote sensing images from Landsat satellites processed using geographic information systems (GIS). The findings showed an increase in the water bodies class where shrimp farms are found. In addition, to help us discuss the results, data from the Global Surface Water Explorer was also used to understand this change throughout intra and interannual water variability. Besides shrimp farms’ intensification, agricultural areas in the LJRSB also increased, mainly in the irrigated perimeter lands (IPLs), causing a loss in the Caatinga native vegetation. In summary, over recent years, significant changes have been noticeable in the LJRSB coastal region, caused by an increase in shrimp farms mainly located on the Jaguaribe River margins, destroying the native riparian forest.

“…Todos esses fatores têm aumentado a vulnerabilidade social no semiárido (Vieira et al, 2020), que historicamente teve sua mão de obra explorada nos latifúndios e atualmente isso se repete nas empresas do agronegócio. Apesar de ter um histórico de reforma agrária na década de 1990, a população do município de Apodi vivenciou uma mudança drástica no sistema produtivo em 2011, quando o governo desapropriou mais de 13 mil hectares de terras para instalação de um perímetro irrigado e empresas do agronegócio, o que tem gerado diversos conflitos (BRASIL, 2011;Pinto et al, 2015;Pinto Filho e Lunes, 2019;Rêgo et al, 2021).…”

Apodi, like many municipalities in the Northeast, underwent structural changes conducted by two main drivers: alternation of socioeconomic models and seasonal and prolonged periods of drought. Among the socioeconomic models, Apodi passed by large landowners, agrarian reform, expropriation of land for irrigated perimeters and installation of agribusiness companies. These conditions negatively impacted the vegetation cover, degrading the landscape and threatening the Lajedo de Soledade Archaeological Site (SALS) located in the middle of this landscape, an important cultural and environmental patrimony. In this context, the objective of this study was to analyze the spatio-temporal changes in the landscape around SALS and to infer about the influence of socioeconomic and environmental drivers. For this, a survey of the region's history, precipitation data, agricultural production of the main crops, and eight images captured by the TM and OLI sensors of the LANDSAT 5 and 8 satellites, between 1984 and 2018, were used. Precipitation data was modeled using the Standardized Precipitation Index (SPI). The images were classified using the SCP plugin (QGIS) and the quality was assessed using the Kappa Index. It was observed that there were three prolonged and extreme droughts events in the region: late 1980s and 1990s and between 2013 and 2017. The classification of the images indicated periods of dense vegetation reductions and exposed soil expansions, in the period of decay of cotton culture, and the reversal of these patterns after agrarian reform, with the establishment of family farming on an agroecological basis. This pattern was again reversed, with the lowest proportion of dense vegetation observed (5%) and and higher proportion of exposed soil (45%) observed in this landscape, during the period of installation of the irrigated perimeter for agribusiness. Thus, it was possible to infer that the alternation of socioeconomic models conditioned the spatio-temporal dynamics of the vegetation cover and was responsible for the environmental degradation conditions surrounding the SALS, these patterns being aggravated by the recurrence of periods of extreme and prolonged drought. During these periods, SALS was probably more vulnerable to the direct and indirect effects of anthropogenic activities common in this landscape.
