To identify the depositional processes and provenance, we carried out geochemical, mineralogical, SEM, and grain-size analyses. Optically stimulated luminescence (OSL) dating shows the aeolian deposits are from the late Holocene (1.0-4.8 ka). Our results demonstrate that the loess and loess-like deposits (i) were dominantly sourced locally from deflation Quaternary sediments of the Terai Plain; (ii) are related to the composition of Siwalik rocks; and (iii) were deposited during dry periods of weak activity of the Indian Summer Monsoon.

De manera especial, también quiero agradecerle a él y a su familia (Samia, Ada y Clara) por abrirme las puertas de su casa en USA. Mi co-director de beca de CONICET: Carlos Ramonell, por su paciencia, dedicación, enseñanzas y priorizar siempre mi formación. Mi co-director de tesis: Martín Hurtado, por su generosidad, confianza y apoyo. A los miembros del Jurado: Dres. Osvaldo Gentile, Susana Degiovanni y Gonzalo Veiga, por las observaciones y correcciones del manuscrito, las cuales mejoraron al mismo.

From this surprising result, we learn that local savanna coverage may not necessarily be enough to influence and dominate the pollen spectrum recorded in the lake sediments when rainforest is widespread in the surrounding areas. Therefore, even a minor proportion of tall forest in a savanna environment can have a significant influence on pollen deposition, masking the savanna signal in the stratigraphic record. Thus, when interpreting the last glacial pollen record of Carajás, the increased abundance of savanna taxa is an unequivocal indicator of local to regional savannas expansion. The postulation of a continued rainforest formation during the glacial times is an unsustainable alternative.

Aggregates constitute the foundation for modern civilization and are essential for providing shelter (concrete-buildings), movement (transport infrastructure) and communication (silicabased electronic devices). With rapid population growth, climate change and anthropogenic pressures on the natural environment, sand and gravel are becoming scarce resources, such that global demand for aggregates is expected to exceed rates of natural renewal within the next 20 years. Here, we review the interconnections between the impacts of aggregate mining and the services they provide. Our assessment shows that societal benefits gained from aggregate resource mining arise from economic gains and the ability to improve livelihoods. However, the conflicting impacts on the environment and humankind disrupts the net positive effects of aggregate mining on sustainable development. With a focus on low-and middle-income countries, we link these interconnections to the United Nations Sustainable Development Goals and identify critical obstacles to a sustainable future for global aggregate resources. Our assessment identifies an urgent need to improve knowledge on: (1) direct and indirect impacts of extraction on human health, (2) system-level impacts on ecosystems and the services they provide, and (3) how to meet the projected trajectories of global aggregate demand. Without such knowledge, policies cannot be developed to help mitigate the negative effects of extraction, while at the same time maintaining the value of this critical commodity for communities and economies around the world.
