Aravali Safari Park Project

Context: Environmental activists opposes Haryana’s Aravali Zoo Safari Project for violating environmental norms.
Aravali Safari Park Project
- Envisioned as the world’s largest safari park, covering approximately 10,000 acres.
- The project is inspired by UAE’s Sharjah Park model.
- Aims to promote eco-tourism and facilitate compensatory afforestation.
- Development will be restricted to areas where forest density is less than 40%.
- Compensatory Afforestation Context: Designed to compensate for the loss of 26,000 acres of tropical forests in Great Nicobar
- Forest (Conservation) Act, 1980 was amended in 2023
- The amendment brought zoo development under ‘forest’ activity classification.
- This legal change now permits construction of zoos in forest areas
Aravali Mountain Range
- Geographical Features:
- The Aravallis are the world’s oldest fold mountain range.
- The range runs diagonally (northeast to southwest) for approximately 690 km.
- It extends across Gujarat, Rajasthan, Delhi, and Haryana.
- The highest peak is Guru Shikhar on Mount Abu (Rajasthan) at 1,722 metres.
- Ecological Significance:
- The range plays a critical role in preventing eastward desertification.
- It is essential for groundwater recharge in the region.
- The hidden limb of Aravallis extends from Delhi to Haridwar.
- This hidden extension separates the drainage systems of the Ganga and Indus rivers.
North-East Monsoon

Syllabus: Physical, Social, Economic Geography of India
Context: The northeast monsoon arrived timely thus benefiting Tamil Nadu and Andhra Pradesh’s coastal and Rayalaseema regions.
Northeast Monsoon (Retreating Monsoon)
- The Northeast Monsoon, also called the Retreating Monsoon, occurs during October to December.Â
- It is characterized by winds flowing from the northeast direction towards the Indian subcontinent. These winds originate as northeast trade winds and carry moisture from the Bay of Bengal.
Geographical Coverage:
- Primarily impacts southeastern India, particularly Tamil Nadu and coastal Andhra Pradesh.
- The northeast monsoon accounts for 48% of annual rainfall for Tamil Nadu and over 30% for Andhra Pradesh based on 1971-2020 data.
- They receives substantial rainfall due to the rain shadow effect. Western regions experience relatively dry conditions during this period.
- Kerala also receives rainfall during this season, referred to as its second rainy period.
Characteristics and Mechanism
- Seasonal Features:
- Marks the transition phase from the rainy season to winter.
- Brings cooler temperatures and helps reduce the residual heat from summer.
- Rainfall is generally less intense than the Southwest Monsoon but remains significant for affected regions.
- Shows seasonal variability, with some years experiencing heavier rainfall than others.
- Mechanism of Formation:
- The sun’s southward movement shifts the monsoon trough or low-pressure areas towards the south.
- This leads to the weakening of troughs over Northern Plains by October.
- High-pressure systems develop over the Northern Plains as cold winds descend from the Himalayas and Indo-Gangetic Plains.
- By early October, monsoons withdraw from Northern India, and the Northeast Monsoon begins affecting southeastern regions.
Significance
- Agricultural and Water Resource Significance:
- The Northeast Monsoon is crucial for replenishing water supplies in regions that receive less rain during the Southwest Monsoon.
- Typically witnesses at least three cyclonic disturbances over the Bay of Bengal each season.
- Ecological Impact:
- Winter rainfall from this monsoon has enabled the development of dry evergreen forests along Tamil Nadu’s coastal areas.
- The monsoon helps maintain ecological balance in southeastern regions.
Southwest vs Northeast Monsoon
| Aspect | Southwest Monsoon | Northeast Monsoon |
| Season | June to September | October to December |
| Wind Direction | Southwest to Northeast | Northeast to Southwest |
| Moisture Source | Indian Ocean | Bay of Bengal |
| Regions Affected | Most of India | Southeastern Coast (Tamil Nadu, Andhra Pradesh) |
| Rainfall Intensity | Heavy Rainfall | Moderate Rainfall |
