“…Also, low values of TOC stock (2.70-6.55 Mg ha −1 ) and TN stock (0.59-0.90 Mg ha −1 ) were found by [39] for Quartzarenic Neosol in the Brazilian semi-arid tropics. Further, [40] observed low values in soil carbon stock (5.29-9.45 Mg ha −1 ) in DC areas under Neosols.…”

Total organic carbon (TOC) and total nitrogen (TN) concentration in the soil are an indicator of soil degradation. To understand how land-use may impact these concentrations in seasonally dry tropical forests (SDTF), we analyzed the effect of four land-uses on TOC stocks (STK.TOC) and TN stocks (STK.TN) in a semi-arid region of Brazil. Soil samples were collected in 12 trenches (three sites × four land-uses—dense caatinga (DC), open caatinga (OC), pasture (PA) and agriculture (AG)), in the 0–10; 10–20 and 20–30 cm layers or as far as the bedrock. The data were compared by the Kruskal–Wallis test (p ≤ 0.05) and similarity investigated by cluster analysis. STK.TOC and STK.TN the surface layer (0–10 cm) showed no significant difference (p ≤ 0.05) between the DC; OC and PA land-uses. The similarity in STK.TOC and STK.TN values between DC, OC and PA, indicate that it is possible to explore SDTF to produce biomass and protein by adopting open caatinga and pasture land uses on Neosols with very low TOC stocks. The greatest reduction in STK.TOC and STK.TN in the agriculture land-use may lead to soil degradation and contribute to the addition of CO2 to the atmosphere.

“…The agriculture class in 2015, 2017, and 2019 showed territorial occupation of 34,209, 35,678, and 36,718 ha, respectively, with an average increase of 0.80% (3616 ha) compared to 2013 (Table 2). This growth was favored by the development of irrigated agriculture in the region, due to the proximity of the São Francisco river's channel, maximizing mainly fruit farming, e.g., grape and mango [6,7]. Most of the times, irrigated fields are inserted in areas previously occupied by Caatinga, which results in changes in the physical, chemical, and biological soil properties [6,66].…”

“…The municipality of Petrolina, PE, Brazil, is located in the semi-arid region of the Caatinga biome. It is within the hydrographic basin of the São Francisco river, which favors the development of irrigated agriculture in the region, mainly fruit-growing (e.g., grapes and mangoes) [6][7][8], and it leads to positive socioeconomic implications, but also increases conflicts regarding water use [2,9].…”

Using Remote Sensing to Quantify the Joint Effects of Climate and Land Use/Land Cover Changes on the Caatinga Biome of Northeast Brazilian

Caatinga biome, located in the Brazilian semi-arid region, is the most populous semi-arid region in the world, causing intensification in land degradation and loss of biodiversity over time. The main objective of this paper is to determine and analyze the changes in land cover and use, over time, on the biophysical parameters in the Caatinga biome in the semi-arid region of Brazil using remote sensing. Landsat-8 images were used, along with the Surface Energy Balance Algorithm for Land (SEBAL) in the Google Earth Engine platform, from 2013 to 2019, through spatiotemporal modeling of vegetation indices, i.e., leaf area index (LAI) and vegetation cover (VC). Moreover, land surface temperature (LST) and actual evapotranspiration (ETa) in Petrolina, the semi-arid region of Brazil, was used. The principal component analysis was used to select descriptive variables and multiple regression analysis to predict ETa. The results indicated significant effects of land use and land cover changes on energy balances over time. In 2013, 70.2% of the study area was composed of Caatinga, while the lowest percentages were identified in 2015 (67.8%) and 2017 (68.7%). Rainfall records in 2013 ranged from 270 to 480 mm, with values higher than 410 mm in 46.5% of the study area, concentrated in the northern part of the municipality. On the other hand, in 2017 the lowest annual rainfall values (from 200 to 340 mm) occurred. Low vegetation cover rate was observed by LAI and VC values, with a range of 0 to 25% vegetation cover in 52.3% of the area, which exposes the effects of the dry season on vegetation. The highest LST was mainly found in urban areas and/or exposed soil. In 2013, 40.5% of the region’s area had LST between 48.0 and 52.0 °C, raising ETa rates (~4.7 mm day−1). Our model has shown good outcomes in terms of accuracy and concordance (coefficient of determination = 0.98, root mean square error = 0.498, and Lin’s concordance correlation coefficient = 0.907). The significant increase in agricultural areas has resulted in the progressive reduction of the Caatinga biome. Therefore, mitigation and sustainable planning is vital to decrease the impacts of anthropic actions.

“…Em geral, mudanças no uso do solo geram perdas significativas dos ECS em comparação a ambientes não alterados (Bordonal et al, 2017), em contrapartida, ao longo dos anos sistemas conservacionistas tendem a recuperar e superar o carbono perdido em comparação a matas nativas (Cassol et al, 2019;Santos et al, 2019b).…”

Atividades antrópicas têm causado a elevação da concentração dos gases de efeito estufa na atmosfera, principalmente devido mudanças causadas no uso da terra, que alteram a capacidade dos solos em armazenar o CO2. O presente estudo busca revisar publicações atuais sobre mudanças no estoque de carbono do solo sob diferentes coberturas vegetais publicados nos últimos anos e realizar uma avaliação crítica e sistêmica do assunto, considerando as metodologias utilizadas em cada trabalho e os diferentes tipos de manejo e uso dos solos em várias regiões do Brasil. Para a coleta de dados foram selecionados 35 artigos publicados nos últimos dez anos que se correlacionavam com o tema. Feito o levantamento dos artigos buscou-se caracterizar os ecossistemas brasileiros e resumir os principais dados publicados sobre os estoques de carbono nos ecossistemas e posteriormente os as estimativas dos estoques em ambientes sob mudança uso do solo. Os resultados apontaram que as diferentes coberturas vegetais apresentam distintas, entretanto positiva capacidade em estocar carbono no solo no Brasil e que variáveis como o manejo, a textura, atributos físicos, químicos e biológicos são fatores significativos e podem e influenciam diretamente nos resultados.
