Fimbristylis agasthyamalaensis: New plant species discovered in Western Ghats 


Researchers have found new grass-like plant species named Fimbristylis agasthyamalaensis in Ponmudi hills within the Agasthyamala Biosphere Reserve in the Western Ghats biodiversity hotspot. It has been classified as sedge, the grass-like plant and has been given the same name as an area from which it was discovered.

Key Facts 


The new class of plant have its place in the Cyperaceae family. Its blossoming and ripening have been witnessed from October to March. In India, Cyperaceae genus is characterized by 122 species, of which 87 are described in the Western Ghats. A range of the recognized Cyperaceae species are therapeutic plants or used as silage.

Threats

Fimbristylis agasthyamalaensis is extremely susceptible to wild cropping. It is also dependent on anthropogenic densities for that reason that its environment falls in travel corner and limit of the place of adoration that possibly will bring about its destruction in the dearth of scientific conservation. Researchers have suggested preliminary conservation assessment of plant as ‘decisively in danger of extinction,’ as stated by IUCN standards.

Agasthyamala Biosphere Reserve (ABR) 


ABR in located farthest south of the Western Ghats and distributed in two southern nations Kerala and Tamil Nadu.  It was founded in 2001. It has been given its name as Agastya Mala peak that mounts to nearly 1868 meters on top of sea level, in Thiruvananthapuram, Kerala.  In March 2016, it was counted in the World Network of Biosphere Reserves of UNESCO.

Its flora frequently depends on tropical forests and is dwelling to 2,254 type of advanced plants counting approximately 400 that remain pervasive.

It is also a habitation of uncommon rife animals comprise tiger, Asian Elephant, and Nilgiri Tahr. It is home to Kanikaran tribe, one of the first living prehistoric communities in the world.

India at risk of food shortage due to climate change- Study 


In proportion to lately issued international study, India is among countries which are at extreme peril of nutrition uncertainty as a result of climate excesses produced by climate change. The study had examined how climate change could affect the exposure of diverse nations largely 122 emerging and least-developed countries (regularly in Asia, Africa, and South America) to food uncertainty when people are in want of access amount of reasonable, wholesome food.

Key Findings 


Climate change affected by 2 degrees Celsius global warming is predicted to bring about more dissipations of both heavy precipitation and scarcity, with diverse results in the parts poles apart. These weather dissipations will upsurge susceptibility to food uncertainty. The countries with utmost susceptibility to sustenance uncertainty owing to climate change remain Oman, India, Bangladesh, Saudi Arabia and Brazil.

Global warming is likely to initiate drizzlier environments averagely triggering floods and putting food manufacture in jeopardy. But agriculture could as well get damaged by more recurrent and continued scarcities in some areas set off by weather variation.
