Phase IFoundation

Background

Overview

UPSC emphasizes India's rich biodiversity, its hotspots, the importance of endemic species, and the role of genetic resources in agriculture and sustainable development. Questions often cover conservation efforts, scientific discoveries, and the institutions involved in biodiversity documentation.

Biodiversity hotspots are biogeographic regions with significant levels of biodiversity that are threatened by human habitation. India is home to four such hotspots, including the Andaman & Nicobar Islands, which harbor a high number of endemic species. Genetic resources, particularly wild relatives of cultivated crops, are invaluable for crop improvement, disease resistance, and adaptation to climate change, forming a critical component of food security.

Facts & tables

Key facts

New Species Discovery

Discovery of Solanum pandeyi, a new wild brinjal species, in the evergreen forests of Middle Andaman.

Biodiversity Hotspot Status

Andaman & Nicobar Islands are recognized as a biological hotspot, known for high endemism and unique flora.

Genetic Potential

Wild relatives of crops like Solanum pandeyi possess genetic potential for developing high-yielding, disease-resistant varieties of cultivated crops.

Conservation Status

The species' conservation status is currently assessed as 'Data Deficient,' indicating a need for further research and assessment.
