“…The idea of no-till farming to protect the soil, the creation of the sanitary break period to avoid the proliferation of pests from one perennial crop to another, was only possible with the technological implementation in the agricultural sector. According to (HORÁK-TERRA, et al [20]), the cerrado or savanna is a region of an ecosystem of high complexity and great possibility of environmental recovery, with a range of approximately 18,000 km2, acid pH, high humidity, rich in minerals and fiber, with predominantly hydromorphic soils. The population growth has necessarily brought the need to increase production (WILKINSON, 2010), (MALUF, et al [21]), opening new areas either for the perennial cultivation of cereals, sugar and alcohol.…”

In several countries, without exception, the environmental costs of various human activities continue to grow National and international legal parameters, bilateral exploration treaties, along with global socioeconomic moments have greatly changed the position of the legislator and the responsible manager in Brazil regarding respect for the environment, and a sustainable development. The objective of this study is, by means of an exploratory bibliographical research, to verify the national advances achieved in defense of fauna and flora, as well as the legal setbacks imposed by an increasing exploitation of production as a way of strengthening the balance of trade, but which leaves a relevant environmental impact. The time elapsed between the entry into force of a law and the decrees that regulate it is very long and needs to be reviewed by the current legislators The assumption that the lack of a more effective and immediate approach to the conservation of natural resources has influenced and directly influences the environmental and climatic condition the planet is in is what is expected to prove.

“…The Cerrado biome has great environmental, social and economic importance for Brazil, and research applied to climate change is of strategic value to the country. Therefore, efforts to understand the evolution of Cerrado landscapes, and how environmental changes modify the distribution of species and biomes, have increased in recent decades (De Oliveira, 1992; Ledru, 1993; Behling, 1995, 2002, 2003; Ledru et al , 1996; Pessenda et al , 1996, 2004; Behling and Lichte, 1997; Parizzi et al , 1998; Rodrigues‐Filho et al , 2002; Turcq et al , 2002; Silva et al , 2004, 2019; Araújo et al , 2005; Missura and Corrêa, 2007; Enters et al , 2010; Horák et al , 2011; Horák‐Terra et al , 2014, 2015, 2020, 2022; Gomes et al , 2017; Costa, 2018; Trindade, 2020; Machado et al , 2021; Costa et al , 2022).…”

The Cerrado biome is the second largest in Brazil, but the evolution of the Cerrado during the late Quaternary is not yet fully known. This study identifies paleoenvironmental changes during the last 23 000 years, based on a tropical mountain peatland record, in the Serra do Espinhaço Meridional in central-eastern Brazil. A multi-proxy approach was used that involved palynological analysis, stable isotopes (δ 13 C, δ 15 N), geochemistry, radiocarbon dating and multivariate statistics derived from a peatland core from Rio Preto (Minas Gerais state). The study reveals a very humid and cold climate during the late Pleistocene, with an increase in temperature and decrease in humidity at the Pleistocene-Holocene transition. During this period there was strong instability in the landscape (episodes of erosion). At the beginning of the Holocene there was a reduction in humidity with greater landscape stability. The current sub-humid climatic conditions seem to have been established in the mid-/late Holocene, with periods of landscape instability. Our findings agree with other Cerrado records that contradict previously established hypotheses, such as the Amazonian Refuge and the Pleistocene Arc.
