Reduction in rainfall across Kerala over past century with Peermade Annual Rainfall reduced from 5165 mm from 4428 mm

Peermade (-737 mm), Kottayam (-404), Punalur (-399), Tiruvalla (-361) and Alappuzha (-269) are those stations in the State which have witnessed significant reduction in their annual rainfall during the last century. Y.E.A. Raj, Deputy Director-General, Regional Meteorological Centre, Chennai, revealed this during a special address at the Kerala Environment Congress 2012 here. 

The topic of his address was ‘Extent of climate change over India and its projected impact on Indian agriculture.’Climate change in respect of individual stations manifests with mixed trends with positive and negative changes, he said. For instance, positive trends are available from stations such as Kochi (+ 100.6 mm) and Kasaragod (+153.5 mm) in annual rainfall in the State.

“It must be stated here that rainfall series for individual months/seasons in some of the series may have shown a significant trend.In some other cases, these trends would have manifested only recently.
“A more detailed analysis of time series must be performed to detect and analyse such incidence,” Raj said. 

The scenario of significant climate change, especially global warming, is now well documented and the evidence incontrovertible. However, in the Indian context, there appears to be no clear signal of such change at least in crucial parameters such as rainfall and occurrence of cyclonic storms. 

Projected climate change based on various models suggests steady increase in temperature and, at a later stage, slight increase in rainfall. The effect on agriculture is likely to be mixed, Raj said. The increase in carbon dioxide in the atmosphere initially favours agricultural production.But increase in temperature would have exactly the reverse effect. The situation is fluid and could even be seen to be contradictory at times. This calls for learnt and measures responses based on scientific facts free from transnational biases.

Amgaon in Karnataka is the New Cherrapunji of South India displaces both Hulikal & Agumbe

Residents at Hulikal in the Shimoga district, who had been basking in the fame of their village replacing its neighbour in Shimoga district, Agumbe, as the Cherrapunji of South India, have some disheartening news. Amgaon, a remote village in North Karnataka, now wears that crown.

The tiny Amgaon, which nestles in the dense forests of the Western Ghats in the Khanapur taluk of Belgaum district
has reached the magical figure of 10,000 mm annual rainfall twice in the last six years. The surroundings of the village located in the Bhimgad Wildlife Sanctuary have been declared a protected area for medicinal plants.

Thrice in the last six year, Amgaon received more rain than Agumbe and Hulikal. In the last two years (2010 and 2011), it received more rain than its peers in in the heart of Malnad, the region in central-west Karnataka which literally means region of rain. In 2011, Agumbe got 7733 mm and Hulikal around 8700 mm. While Amagaon got around 9105 mm.

Of course, Cherrapunji in Meghalaya, the byword for rain for over a century, has been overtaken by Mawsynram, its neighbour. The average rainfall in both places is in 11,800 mm rain each year, with Mawynram just a nose ahead. The world record, held by Cherrapunji, is a monstrous 26,461 mm recorded between August 1, 1860, and July 31, 1861. Mawsynram almost snatched that record with 26,000 mm in 1985. Amgaon is not in the same league, but recording 10,000 mm is not to be scoffed at. At least, outside the two rain record holders in Meghalaya.

The tiny village is a paradise for nature lovers and trekkers. In monsoon, the Bail Nala, a tributary of the Malaprabha river, blocks the bumpy road to Amgaon, making a two-km walk mandatory.Part of the Amate Gram Panchayat, this village is at a distance of around 35 km from Khanapur town. “We have around 70 houses here. The population of about 300 speak Marathi. Paddy is the main crop. We have a lower primary school in our village, and a government doctor visits the place every Tuesday. If we need to go to the town, we have to walk for about seven km in the forest to catch a bus. In summer, MUVs ferry people to and from our village,” says Laxman Sahadev Ghadi, a resident of Amgaon.

Siddappa Y Barki, a forest guard who visits the village almost daily, feels the residents there are very healthy and are accustomed to heavy rainfall.

Though the arrival of monsoon was delayed this time, Amgaon received 4541 mm rainfall till  August 15, 2012. In the similar period, Agumbe has got 4883 mm and Kollur another HRF (Heavy Rainfall station in Karnataka got 4676 mm.
