Resumen

Las actividades humanas, tanto superficiales como profundas, contribuyen significativamente al hundimiento de la tierra. Comprender estos impactos es crucial para gestionar los cambios geológicos y la planificación urbana.

Área de la Ciencia:

Ciencias de la Tierra
Ciencias del medio ambiente
Ingeniería civil

Sus antecedentes:

El hundimiento de la tierra es un peligro geológico crítico.
Las actividades humanas son cada vez más reconocidas como factores de hundimiento.
La cuantificación de la contribución de las diferentes actividades es esencial para la mitigación.

Objetivo del estudio:

Investigar el papel de las actividades humanas subterráneas superficiales y profundas en el hundimiento de la tierra.
Diferenciar los impactos de varios procesos inducidos por el hombre en el hundimiento.
Proporcionar una comprensión completa del hundimiento antropogénico.

Principales métodos:

Análisis de datos geológicos y registros de actividad subterránea.
Modelado de la deformación del suelo debido a las intervenciones humanas.
Evaluación espacial y temporal de los patrones de hundimiento.

Principales resultados:

Tanto las actividades humanas superficiales como las profundas contribuyen significativamente al hundimiento total de la tierra.
Se identificaron como factores importantes actividades específicas como la extracción de aguas subterráneas y la construcción subterránea.
El efecto acumulado de estas actividades exacerba las tasas de hundimiento.

Conclusiones:

Las actividades humanas subterráneas son el principal impulsor del hundimiento de la tierra.
La planificación efectiva del uso del suelo y la regulación de las actividades subterráneas son necesarias para mitigar el hundimiento.
Las investigaciones adicionales deben centrarse en el monitoreo a largo plazo y el modelado predictivo.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
