Adapting agriculture to drought and extreme events [PDF]

Journal of Soil and Water Conservation, 2012
T he 2012 drought, one of the worst during the last 80 years or more, reminds us of the dust bowl of the 1930s (figure 1) and indicates that climate change is a reality rather than a distant threat. The drought has had a severe impact on yields, reducing the predicted grain production for corn per acre at a farm level to levels of production that have ...

Extreme droughts and floods in the Amazon forest

, 2022
<p>In recent years, the Amazon forest has experienced several major droughts (2010, 2015/16) and floods (2012, 2014, 2021). Extreme events represent a threat to the Amazons important functions, but these perturbations also provide valuable insights into the underlying mechanisms.

When does extreme drought elicit extreme ecological responses? [PDF]

Journal of Ecology, 2019
Abstract Global climate change models predict an increase in the frequency and intensity of extreme droughts, with uncertain ecological impacts across ecosystems. In particular, it is not clear when extreme droughts will elicit extreme ecological responses.

Phenological responses to extreme droughts in a Mediterranean forest

Global Change Biology, 2010
AbstractMediterranean regions are projected to experience more frequent, prolonged and severe drought as a consequence of climate change. We used a retractable rainfall shelter, to investigate the impact of extreme droughts on the development of Quercus ilex leaves, flowers and fruit.

Belowground niche partitioning is maintained under extreme drought

Ecology, 2023
AbstractBelowground niche partitioning presents a key mechanism for maintaining species coexistence and diversity. Its importance is currently reinforced by climate change that alters soil hydrological conditions. However, experimental tests examining the magnitude of its change under climate change are scarce. We combined measurements of oxygen stable

Aboveground net primary productivity not CO2 exchange remain stable under three timing of extreme drought in a semi-arid steppe.

PLoS ONE, 2019
Precipitation patterns are expected to change in the semi-arid region within the next decades, with projected increasing in extreme drought events. Meanwhile, the timing of extreme drought also shows great uncertainty, suggesting that the timing of ...

Extreme value analysis of wind droughts in Great Britain

Renewable Energy, 2023
Due to the growing proportion of wind energy in Great Britain’s energy mix, prolonged periods of low wind power generation have become a significant challenge for decarbonising the electricity system. As such, characterising drought severity and duration is important for ensuring the reliability of the electricity system.

NLSS3 Impairs SHM1 Autophagic Degradation to Regulate Leaf Morphology and Salt Tolerance in Rice

Advanced Science, EarlyView.
In rice, NLSS3 binds and shields SHM1 from autophagic degradation to maintain serine homeostasis. The A132P mutation in nlss3 disrupts this, triggering SHM1 loss, metabolic dysfunction, K+ imbalance, and impaired ROS scavenging, which collectively drive narrow leaves and salt sensitivity.

Droughts with no agro-climatological extremes

Scientific Reports
While droughts are primarily linked to climatic conditions, socio-economic factors, such as social vulnerability to drought, significantly influence the impact of drought events. In many vulnerable regions, droughts can occur even when there are minor or no significant deviations from typical agro-climatological conditions.
