Análise Integrada dos Brejos de Altitude do Nordeste do Brasil a partir de Atributos Fisiográficos / Integrated Analysis of Highland Humid Brejos in Northeast Brazil Based on Physiographic Attributes

Abstract

Brejos de altitude são áreas de exceção climato-edáfico-ecológicas inseridas no domínio semiárido do Nordeste do Brasil, apresentando uma variação paisagística bastante expressiva. Suas peculiaridades mesológicas, quando comparados com o entorno e entre si, têm despertado o interesse de pesquisadores tanto para fins de caracterização quanto de planejamento, uma vez que essas áreas possuem valor ambiental e econômico expressivos no contexto semiárido brasileiro. Neste sentido, o objetivo desse trabalho é reunir e discutir as principais características fisiográficas já estabelecidas para os brejos de altitude. Foram consultados periódicos, teses, dissertações, livros e relatórios técnicos que se propuseram a definir e caracterizar os brejos de altitude nordestinos. Ao final, foi possível contabilizar um total de 10 áreas classificadas como enclaves, bem como definir os atributos fisiográficos que as definem. Essas características geraram um quadro síntese que permitiu a realização de uma análise comparativa a partir dos elementos descritivos identificados em cada obra consultada.

The climate and climatological water balance of Brazilian semi-arid mountainous areas and inland depression

“…Therefore, these high-altitude areas can be more or less humid depending on their position/ orientation in relation to the winds and moister air masses from the Atlantic Ocean. They have been studied and require special attention as (due to their particularities) they are considered areas of prominence, especially for the practiced agricultural activities, such as subsistence polyculture (GOIS et al, 2019), and their tourism potential, particularly ecotourism (BARBOSA et al, 2016;NASCIMENTO et al, 2022).…”

Characterization and Classification of Soils in Agroecosystems in a Moist Enclave in Northeastern Brazil

“…Moreover, there are areas with different rainfall and temperature patterns within zones considered semi-arid. These exceptional areas are called Caatinga moist-forest enclaves or 'brejos de altitude' [6].…”

“…The 'brejos de altitude' areas show an interaction between the geomorphological factor, represented by the relief, and the climate, favoring orographic precipitation [6]. From this perspective, the Serra de Martins mountains in the municipality of Martins-RN acts as a physical barrier that favors the development of orographic rainfall, responsible for the Land 2023, 12, 1881 2 of 15 higher precipitation volume in relation to the surrounding areas located in the Depressão Sertaneja lowlands [7].…”

Methodology for mapping the distribution of altitudinal wetland forests in the Brazilian Semiarid

“…In addition to the problems mentioned above, there is also a lack of updated information on the location of these altitudinal rain forests in the semiarid region. Some studies have attempted to define areas where these wet enclaves are likely to occur, as in the case of Tabarelli and Santos (2004); Souza and Oliveira (2006); Rodrigues et al, (2008); Brandão et al, (2016); GOIS et al, 2019; however, there are likely places with altitudinal rain forests that have not yet been identified, some projects have mapped the land surface in Disponível em: https://periodicos.ufsm.br/geografia/article/view/47918 Brazil, such as mapbiomas, but have not included the altitudinal rain forests in their research, thus is a need for studies performing in this location.…”
