The correct answer is Restoration of degraded forest patches in Aravalli range.

Key Points

• The Aravalli Green Wall Project was launched in 2023 by the Ministry of Environment, Forest, and Climate Change (MoEFCC) to address environmental degradation in the Aravalli range.
• The initiative focuses on restoring degraded forest lands in the Aravalli range, which spans across Haryana, Rajasthan, Gujarat, and Delhi.
• The project aims to increase green cover and biodiversity in the region, thereby mitigating the adverse effects of desertification and climate change.
• One of the key objectives is to create a continuous green barrier along the Aravalli range to prevent the spread of the Thar Desert and improve ecosystem services.
• The project involves community participation, afforestation drives, and soil conservation measures to restore the ecological balance of the region.

Additional Information

• Afforestation in Himalayan States
• Afforestation efforts in Himalayan states focus on increasing forest cover in ecologically sensitive areas, which are crucial for mitigating climate change and preserving biodiversity.
• Such initiatives aim to reduce soil erosion, improve water retention, and support local livelihoods through sustainable forest management.
• These efforts are not directly linked to the Aravalli Green Wall Project, which specifically targets the Aravalli range.
• Building Forest Corridors Across Indo-Gangetic Plains

The correct answer is Deep-sky objects.

Key Points

• Deep-sky objects refer to astronomical entities such as galaxies, nebulae, star clusters, and distant celestial objects that are faint and require dark skies for observation.
• Urban light pollution significantly hampers the visibility of deep-sky objects by increasing the sky brightness, reducing contrast, and obscuring faint objects.
• Light pollution from artificial sources, such as streetlights and buildings, scatters in the atmosphere, overwhelming the faint light emitted by deep-sky objects.
• Observing deep-sky objects typically requires remote locations or observatories situated far from urban areas to minimize the effects of light pollution.
• Efforts to mitigate light pollution, including the use of shielded lighting and adherence to dark-sky standards, are crucial for preserving the visibility of deep-sky objects.

Additional Information

• Sunspots
• Sunspots are dark, cooler areas on the Sun's surface caused by magnetic activity that inhibits convection.
• Observing sunspots does not typically require dark skies, as they can be seen using solar filters or telescopes during the daytime.
• Urban light pollution does not significantly affect the observation of sunspots, as they are observed against the bright background of the Sun.
• Planetary Transit
• Planetary transit occurs when a planet passes in front of its host star, causing a temporary dip in the star's brightness.
• These events are usually studied using telescopes equipped with photometers or spectrometers, and they are not as affected by light pollution as deep-sky objects.
• However, precise measurements of brightness changes may require optimal conditions, which can be influenced by urban light pollution.
• Lunar Phases
• Lunar phases refer to the appearance of the Moon as it orbits Earth, changing its illuminated portion visible from Earth.
• Light pollution has minimal impact on observing lunar phases because the Moon is bright enough to be visible even in urban environments.
• Lunar observation is often used as an introductory activity for amateur astronomers due to its ease of visibility.
• Light Pollution and Astronomy
