Key Findings of the Study

Global Vulnerability and Economic Impact

  • Approximately 11% of the world’s population resides in low-lying coastal areas vulnerable to flooding.
  • These regions contribute around 14% to the global Gross Domestic Product (GDP).

Adaptation Gap Assessment

  • Almost 50% of the surveyed regions showed significant gaps in adaptation efforts, with a focus on individual risks rather than addressing root causes of vulnerability.
  • About 13% of the case studies demonstrated high-to-very-high levels of adaptation, primarily observed in Europe and North America.
  • The remaining regions fell into the moderate category, including Australia and New Zealand.

Specific Region Assessments

  • In India, Mumbai, Puri, Konkan, and the Ghoramara region in Sundarbans displayed varying levels of adaptation measures.
  • Ghoramara exhibited generic adaptation plans but lacked locally tailored state-agency-specific strategies.
  • The Konkan region also lacked adaptation plans, failing to address multiple coastal hazards in the state’s action plan.
  • Mumbai possessed a climate action plan but faced challenges in accurately assessing risks and addressing the specific needs of vulnerable residents.
  • Puri, despite having action plans, lacked sector-specific adaptation strategies and the identification of high-risk communities.

Coastal Adaptation

  • Coastal adaptation involves a set of strategies and actions aimed at mitigating the impact of natural hazards and climate change on coastal regions.
  • Its primary objectives include safeguarding communities and infrastructure from rising sea levels, erosion, and extreme weather events.
Advantages of Coastal Adaptation

Venus’ Tectonic History: Unveiling Earth’s “Sister”

Plate Tectonics on Earth

  • Plate tectonics is a fundamental theory explaining the division of Earth’s outer shell into plates that float on the mantle, shaping our planet’s features and sustaining life.

Venus: Earth’s Enigmatic Twin

  • Venus, a celestial sibling to Earth in size, mass, density, and volume, remains relatively mysterious compared to other terrestrial planets.
Implications of Venus’ Tectonic History
  • Venus’s tectonic history holds significant implications for its atmospheric composition and the potential existence of ancient microbial life.
  • Similarities to Earth’s plate tectonics may have played a vital role in shaping Venus’s atmosphere, rich in carbon dioxide and nitrogen.
  • Understanding Venus’s atmospheric makeup, with around 96.5% carbon dioxide and less than 3.5% nitrogen, is of utmost importance.
  • The study raises the possibility that Venus could have hosted microbial life billions of years ago, influenced by tectonic activities.

Plate Tectonics’ Impact on Venus

Cessation of Plate Tectonics

  • On Venus, plate tectonics may have ceased due to factors like water loss and an increasingly hot and dense atmosphere, potentially depleting the prerequisites for tectonic movements.

Dynamic Planetary States

  • The study suggests that planets can transition in and out of different tectonic states, challenging the idea that tectonics are either entirely present or absent during a planet’s history.

Reevaluating Tectonic Paradigms

  • This realization redefines the conventional binary perspective of tectonics as either true or false throughout a planet’s history.

Future Prospects with DAVINCI

  • To validate their findings and delve deeper into Venus’s tectonic past, researchers anticipate insights from NASA’s upcoming mission to Venus, DAVINCI.
  • This mission holds the potential to offer crucial clues and enhance our understanding of Venus’s geological evolution.

Uncovering Reasons for Tectonic Shift

  • Additionally, researchers aim to elucidate the reasons behind Venus losing its plate tectonics over time, furthering our knowledge of the planet’s geology.

About Venus

  • Venus is the second planet from the Sun and is the brightest natural object in Earth’s night sky after the Moon. It can cast shadows and can be seen with the naked eye on rare occasions, even during daylight.
  • Venus has a unique rotation pattern, where the Sun rises in the west and sets in the east. This is because it rotates in the opposite direction (East to West/Clockwise) to all but Uranus.
  • Venus has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. This causes a strong greenhouse effect, making Venus the hottest planet in the Solar System despite being farther from the Sun than Mercury.
  • The atmospheric pressure at the planet’s surface is about 92 times that of Earth’s sea level pressure.
  • Venus is covered by an opaque layer of highly reflective clouds made of sulfuric acid, which prevents its surface from being seen in visible light.
  • The planet lacks a planetary magnetic field, which caused the water to photo dissociate and the free hydrogen to be swept into interplanetary space by the solar wind.
  • Venus has been a significant fixture in human culture for as long as records have existed.
