Climate Change and Human Activities: Their Roles in Shaping Land Productivity in Northern Nigeria
The Northern Nigeria Region (NNR) has historically suffered from land productivity changes due to anthropogenic and climatic factors. The development of methodologies that can evaluate these changes at the pixel level and spatialize the effects of driving factors is a key requisite to provide targeted solutions for land degradation, in a country with population growth and desert advancement. In this study, we applied MODIS series data to assess l…
Detailed geomorphological cartography of the Fildes Peninsula, South Shetland Islands, Antarctica
On the Antarctic continent, the transition from a warm, ice-free early Eocene to glacial conditions marks the onset of Cenozoic glaciation. The Fildes Peninsula (FP), King George Island, has geological and climatic characteristics that result in specific dynamic geomorphology. This study presents geomorphological mapping of the FP based on literature maps and photointerpretation, focusing on a sample area south of the Chilean Eduardo Frei base. T…
Deforestation in Areas of Higher Suitability Does Not Imply Greater Productivity: The Mismatch Between Environmental and Economic Sustainability in the Cerrado
The expansion of agriculture in the Cerrado has led to the highest deforestation rates in Brazil. The conversion of these areas is not only linked to biodiversity loss and the decline of ecosystem services but also does not result in increased agricultural productivity. Considering the Matopiba region- zone of the Cerrado with the highest deforestation rate in the biome-maintaining the current deforestation rate in areas of highest agricultural p…
Diálogo com Alberto da Costa e Silva: A participação africana na agricultura brasileira e outros movimentos e contribuições transatlânticas1
da Costa e Silva aimed at exploring the ramifications of the African diaspora and its influences on Brazilian agriculture. From this theme, he addressed the topics of food diet, adaptation of agricultural tools, slavery, and mining in Africa, Portugal and Brazil. Costa e Silva listed the peculiarities of the Africans, recognizing them as co-participants in the formation of the Brazilian society. In his speeches the researcher reported upon the ty…
Dinâmica climática e biogeográfica do Brasil no Último Máximo Glacial: O Estado Da Arte
A partir de meados do século XX, cresceu significativamente o interesse em se compreender a dinâmica das vegetações em respostas às mudanças climáticas do Último Máximo Glacial - UMG (18 mil anos atrás). Nesse contexto, uma paisagem pode ser fruto de mudanças recentes ambientais ou relíquias de condições ainda mais remotas. Isso pode determinar, inclusive, o grau de complexidade e diversificação da paisagem. Diversos pesquisadores têm proposto mo…
Climate and soils at the Brazilian semiarid and the forest-Caatinga problem: New insights and implications for conservation
This study aimed to test two hypotheses: (i) on the Brazilian semiarid territory, the climate has greater weight as a driver of vegetation than the soil and; (ii) the arboreal Caatinga is a vegetation whose environmental attributes are similar to the Dry Forest, in terms of soil and climate attributes. We analyzed attributes of the superficial horizon of 156 standardized profiles distributed throughout the Brazilian semiarid region. Bioclimatic v…
Deciphering landscapes through the lenses of locals: The “Territorial Social-Ecological Networks” Framework applied to a Brazilian maroon case
Archaeoanthrosol formation and evolution of the “Santana do Riacho” archaeological shelter: An old burial site in South America
The “Santana do Riacho” shelter is one of the oldest human occupation sites in Brazil. Dated to the Late Pleistocene, this shelter contains over 40 buried individuals. The shelter is located on the edge of the Espinhaço Range in Mesoproterozoic quartzites. This study aims to investigate the relationship between human activities and in situ soil formation. To this end, chemical, physical, X‐ray fluorescence, X‐ray diffraction using synchrotron lig…
O conhecimento local e a etnopedologia no estudo dos agroecossistemas da comunidade quilombola de Brejo dos Crioulos
O presente trabalho buscou identificar, resgatar e valorizar os saberes tradicionais sobre o solo e os agroambientes, estabelecendo uma articulação destes saberes com o conhecimento científico de cunho acadêmico. Para isso, realizou-se uma estratificação dos ambientes do território quilombola de Brejo dos Crioulos, com base em critérios locais e pelo método pedológico convencional, considerando o solo e sua interface com outros componentes ambien…
Geoarqueologia das primeiras ocupações humanas na Antártica
Neste trabalho, apresentam-se os primeiros resultados das pesquisas geoarqueológicas realidas em dois sítios de caçadores de focas dos séculos XVIII/XIX, localizados na Península Byers, Ilhas Shetland do Sul, Antártica. A investigação geoarqueológica em este contexto histórico visa recuperar informações de campo e laboratório, não atingíveis através da análise artefatual e documental, referentes à função do sítios, tempo de ocupação, entre outros…
