Latossolos (Ferralsols) in Brazil’s Northeast semiarid region: what does this “contradiction” reveal?

Latossolos (Ferralsols) in Brazil’s Northeast semiarid region: what does this “contradiction” reveal?

by | Jan 14, 2026 |

Why do Latossolos occur in Brazil’s Northeast semiarid region? Drawing on the paper by Grace Bungenstab Alves, this text shows how reading soil and relief together reveals both legacies from wetter phases and more recent landscape reorganization. Two examples illustrate the argument: Vertisols with Holocene OSL ages and the Latossolo–Planossolo transition. Together, they highlight that separate inventories of soils and landforms do not explain processes, and that transition zones often hold the key evidence for interpretation.

Trapped in the forest: how soil shapes an unusual grassland in the Atlantic Rainforest

Trapped in the forest: how soil shapes an unusual grassland in the Atlantic Rainforest

by | Jul 7, 2025 |

This study investigates the Campo do Veludo, an isolated grassland formation within the Atlantic Forest in southern São Paulo. By integrating soil, topographic, and vegetation data, the research shows that shallow, acidic, and poorly drained Spodosols shape the landscape structure and constrain forest expansion, resulting in a biogeographic enclave of exception. The authors also explore possible connections with muçununga formations, broadening the discussion on landscape diversity in humid tropical regions.

Teacher education and PIBID in times of precarization: critical reflections and possible pathways

Teacher education and PIBID in times of precarization: critical reflections and possible pathways

by | Jun 17, 2025 |

This post critically examines teacher education and the PIBID program in times of precarization, drawing from the book Professor S/A and related works developed within the Colapso/UFBA research group. It discusses how recent changes in public policies have negatively impacted teacher training, while also highlighting experiences and reflections that point to collective resistance and alternative pathways. The publication brings together contributions on the effects of flexible accumulation in education, connecting teaching, research, and political action within the field of Geographic Education.
