“…The results of this study showed a reduction in albedo values for burning areas (10.2 %), followed by forest areas (planted or native) and savanna areas (13.7 to 15.3 %), and, finally, exposed soil areas, agricultural areas and pastures (17.1 to 20.4 %), respectively. Other authors also found similar rates: 8 to 13 % in burning areas (Lyons et al 2008), these values being generally observed immediately after a more severe fire (Quintano et al 2019); 11 to 15 % in forest areas; and 13 to 20 % in pastures (Querino et al 2006, Giongo et al 2009, Silva et al 2015, Veloso et al 2017; 13 to 26 % in agricultural areas; around 13 % in typical Cerrado vegetation (Giongo et al 2009, Veloso et al 2017; and 18 to 45 % in exposed soil areas (Oliveira et al 2013, Veloso et al 2017).…”

“…Corroborating these values, studies such as that by Eltz & Rovedder (2005) also demonstrated that, between different soil covers, the more forested an area, the lower is the temperature close to the ground in that region. Cerrado typologies, and land uses such as agriculture and livestock, generally have higher values of surface temperature (Gusmão et al 2013, Martins et al 2015, Silva et al 2015, Veloso et al 2017. Santos et al (2017) analyzed the Caatinga biome using the SEBAL and showed that the daily evapotranspiration is similar for agricultural areas, grasslands and the characteristic vegetation of that biome, but higher for exposed soil areas and lower for areas with more dense canopies.…”

The monitoring of biophysical indicators can show the conservation or recovery status of a landscape. This study aimed to analyze the influence of tree plantations on the dynamics of biophysical indicators (albedo, NDVI, surface temperature and evapotranspiration), in an experimental area of the Cerrado biome (Brazilian Savanna), by applying remote sensing techniques and the SEBAL algorithm. The indicators dynamics were given as a function of changes in the land use, while assessing the response of the environment to the planting of tree species. SEBAL data on areas that underwent changes in land use and cover during this period were analyzed. In the surroundings of the experimental area, albedo and surface temperature decreased in agricultural and exposed soil areas converted to tree plantations, while the NDVI and evapotranspiration increased. The opposite happened in the conversion of native areas destined to agriculture and livestock. In the experimental area, it was confirmed that the plantations contributed not only to the decrease in the surface and albedo temperature, but also to the increase in the NDVI and evapotranspiration. This confirms the positive influence of tree planting in rural properties of the Cerrado as a support to environmental regularization and more sustainable agricultural systems. Moreover, it highlights the potential of the technique applied to assist in monitoring Cerrado ecosystems in areas larger than those commonly monitored in the field.

“…According to Santos et al (2015) the balance of radiation has high relevance in the processes of air and soil heating, photosynthesis, and evapotranspiration, and it can be reckoned through the descendants, ascendants and radioactive fluxes, including the long and short waves. Silva et al (2015) verified that different coverages of use and occupation of the soil alter the distribution of radiation balance, this way, the capacity of the surface in retaining energy to the physic-biologic process and air heating are modified, consequently, altering the micro weather in all region.…”

The variation of the biophysical parameters is fundamental for the understanding of the dynamics of the land use and coverage in the estimation of the balance of surface radiation.In this context, the objective is to evaluate and validate the surface radiation balance for the Mogi Guaçu River Basin (MGRB) using Landsat-8 images and the Surface Energy Balance Algorithm for Land (SEBAL) algorithm. For the study used a Landsat-8 image orbits 220 and pointed 75 for the day 15/06/2015 and data from automatic stations Pradópolis and São Carlos (SP).The image processing was performed in the Qgis 2.18 software, where it performed the atmospheric correction (reflectance and radiance), then the albedo, temperature, emissivity, vegetation index, short wave and incident finally the radiation balance. The results showed that the dynamics of soil use and cover changes the final radiation balance, once the lowest values of albedo and temperature presented higher values of Normalized Difference Vegetation Index (NDVI) and Radiation balance, whereas higher values of albedo and temperature were noticed lower values of NDVI and Radiation Balance. The relative error obtained by the comparison of the measured and estimated radiation balance was around 4.35% showing the real accuracy of the Landsat-8 images for the estimation.

Forest land provides several environmental services and goods with significant implications for different socioeconomic and environmental dimensions. Forestry and its management are determinant activities for sustainable development, specifically in the current context of urgent mitigation of climate change. In this perspective, one objective of this research was to survey the main insights from the literature about the forest and management dimensions put together, highlighting the contributions of these activities to mitigate climate change. Another objective was to explore indicators related to forest management (land, employment, output, and net emissions) in order to obtain a forest sustainability index through factor analysis. As main insights from this study, we can quote that the literature survey pinpoints the most relevant factors framing forest management: soil characteristics, ecology, ecosystems, biodiversity, deforestation, climate change, socioeconomic frameworks, local knowledge, public policies, institutional context, and new technologies. Forest indicators reveal a strong relationship between forest land, employment and output, and a weaker relation with net emissions. We concluded that there is a need for stakeholders to explore and improve the interlinkage with climate change impact, specifically with regard to improving the relationships of forestry greenhouse gas emissions impacts with forest size and output.
