“…The WQI describes the susceptibility of water bodies, which is related to distances between water resources and sources of impact represented by different land uses [37]. It is based on the functional curves from the Habitat Quality Index [35] and assumes that land use and cover are related to environmental vulnerability of vegetation and water components.…”

Diagnosis of fragmentation and landscape sustainability conditions are essential to environmental planning and sustainable management of natural resources. Land use spatial patterns and landscape structural indexes (landscape metrics, Urbanity Index-UI, and Landscape Vulnerability Index-LVI) have been proposed to assess biodiversity conservation and ecological sustainability, provided by impact of land use at Middle Mogi Guaçu watershed and its seventeen municipalities, in 2009. Land use typologies and structural indexes values were obtained based on screen digitizing of LandSat-5 imagery, for 2009. Cluster analysis and Permutational Multivariate Analysis of Variance were used to test the null hypothesis of equal degrees of fragmentation and sustainability conditions among municipalities in 2009, respectively. Land use spatial pattern showed a predominantly human occupation for watershed and its municipalities, with agricultural use as the main pressure factor. Municipalities were aggregated into three clusters related to forest fragmentation: one categorized by fifteen municipalities; the second cluster (municipality of Luiz Antônio) showing the best condition, and the third group (municipality of Araraquara) with extreme fragmentation condition. Landscape metrics related with shape, size, and core areas fragments intensify edge effects, and increase habitat isolation. The watershed showed a low naturalness and an intermediate degree of vulnerability. Ecological sustainability was different among municipalities (α = 0.05, F = 32.65 and p = 0.002), with two municipalities (Analândia and Luiz Antônio) presenting the best conditions. The most committed condition was observed, in municipalities of Rincão and Guatapará. For conservation policies to be effective must focus on the creation of ecological corridors around legally protected areas, besides creation of new legal reserves, with purpose to improve biodiversity conservation and ecological sustainability of Middle Mogi Guaçu watershed and its municipalities.

“…Os remanescentes de vegetação natural (21,2%) estão distribuídos em pequenos fragmentos ao redor da EEA, formada por dois fragmentos fontes, porém entremeados por matrizes agrícolas e pastos. Essa fragmentação ocorre devido à expansão e à intensificação da agricultura e é comum em paisagem de Mata Atlântica e Savana FUSHITA et al, 2016;SAWAKUCHI, 2010).…”

“…These tools also highlight the relationships between the components of natural and anthropogenic landscapes, and how land use changes can influence ecological sustainability, emphasizing the reduction of naturalness due to the replacement of natural components by anthropic ones, monitored in time and space [12] [19] [20] [21]. Among them, the Urbanity Index was used as an indicator of the extent and intensity of the naturalness of heavily altered landscapes, considering the proportion among areas with anthropic interference and natural and semi-natural areas [22] Comply with the needs to facilitate the integration of planning and priority in designating areas of outstanding environmental value, or even, what natural vegetation patches areas should be kept in view the maintenance and continuity of ecological processes to ensure ecosystemic services provided to human well-being.…”

The effects of land use and cover changes and the application of the Urbanity Index were analyzed to identify critical or non-critical naturalness scenery in the Northern Region of Rio Grande do Sul (Brazil), over a period of 30 years. Between 1986 and 2016, the main significant land use change was the reduction of the agricultural anthropic and the increase of the natural vegetation land use areas. About 90%-80% of the total study areas were characterized by anthropic pattern features, with a predominantly agricultural matrix. The conversion of agricultural anthropic into natural areas resulted in increased naturalness landscape and a gain in the stock of natural capital. The increase in the natural vegetation area, mainly to the north and east of the region, set in a steep relief, became remarkable after 1990. The Urbanity Index values evidenced a highest naturalness condition (natural vegetation areas) to the northern and eastern, while a smaller naturalness condition (agricultural and non-agricultural areas) to the southern and western and central of the Northern Region of Rio Grande do Sul. These changes are related to a non-impaired (northern and eastern) and a impaired scenery (southern, western and central portion) of the ecological sustainability of the Northern Region of Rio Grande do Sul, after a 30-year period (1986-2016). These results pointed out that land use transitions resulted in a consolidated farming scenario in which agricultural intensification coincided with the reduction of farming area and increased naturalness as a reverse trend to the agricultural frontier dynamics.
