A series of studies conducted over a five-year period has substantiated this claim.<br /><br />Speaking to DNA, former head and principal scientist at Indian Council for Agricultural Research, Dr NG Raghu Mohan, who is also a soil and water resource consultant, says Bangalore’s depleting underground water table and shifting seasons are signs of gradual desertification. Earlier, citizens experienced prickly summer heat during March, but now, February seems like summer. The seasons have advanced and the moisture content in the air is almost lost.<br /><br />Dr Mohan has studied the climate and soil of Bangalore over the last decade and says that there is a yardstick to measure desertification. One is when evaporation is more than precipitation. Earlier in Bangalore, evaporation was equal to precipitation, like in Pune, and Bangalore then experienced heavy rainfall. But now, the number of rainy days and quantity of rainfall has reduced. Now, Bangalore receives 540mm and some times 300mm of rainfall, compared to 1000mm it received earlier. <br /><br />Noticeably, vegetation has become scarce in the city and its outskirts.<br /><br />Lakes are vanishing and soil moisture is depleting. Therefore, the number of days the soil can release moisture to the plants has also reduced because of the presence of clay pan. This is presently 50cm below earth’s surface. This restricts soil digging and absorption of moisture.<br /><br />“Desertification is not visible, but it’s occurring gradually. Peripheral areas of Bangalore such as Magadi, Hoskotte and Anekal are also experiencing increased evaporation. Bangalore’s soil is becoming desert-like as rainfall is reducing and summer heat is increasing,” he says. Climate in an area is humid when there is a rainfall of at least 180 days per year, and evaporation is less than precipitation. It’s semi-arid when the number of rainy days is 90; it is arid when there are 60 rainy days and a desert when the number of rainy days is less than 30.<br /><br />Environmentalist AN Yellappa Reddy warns: “If we start exploiting and digging more borewells, underground water will be depleted and Bangalore will become a desert in a few years. The impact of desertification is difficult to assess as little is known. Neither the government nor citizens are concerned about it. The heat island effect is also adding to this.” <br /><br />Studies have proved that glass and concrete structures are adding to the desertification, as the temperature in their vicinity is always high.<br />ssethttps://www.blogger.com/profile/06630570720915417629noreply@blogger.comtag:blogger.com,1999:blog-31136724.post-55466573415986327992012-09-21T22:23:11.309+05:302012-09-21T22:23:11.309+05:30Dear Rajan,

This hot -spot region comprises of Bangalore,Mysore,Mandya,Kolar,Anantpur,chitoor... If we consider same latitude - average Marathwada rain is 4-5 times Bangalore rain, Vidarbha rain is 5-8 times more than Bangalore rain. <br /> <br />SriLanka/TN is facing similar issue of cyclic droughts. Myself sure NEM (higher probability of remaining weak), Bangalore is very likely to face similar drought next year. So what do we conclude out of this?<br /><br />Below link (2010) hold very true today(2012)<br />http://www.dnaindia.com/bangalore/report_garden-city-is-turning-into-a-desert_1375269<br /><br />Thanksssethttps://www.blogger.com/profile/06630570720915417629noreply@blogger.comtag:blogger.com,1999:blog-31136724.post-32376201920135728542012-09-21T22:01:06.980+05:302012-09-21T22:01:06.980+05:30Dear Rajesh sir,
You are correct in your observa...Dear Rajesh sir,<br /> You are correct in your observations that forest do influence in very lesser proportions in weather especially in rainfall. <br />Both SIK / NIK not getting sufficient rainfall in this SWM 2012 is mainly due to less prominence of off shower monsoon trough usually present over AS. Further no monsoon depression is strong enough to penetrate into SIK or NIK.<br />At 850 hPa level the eastern side of western ghat continuously warmer [20 Deg Celsius] and clouding and due to warm air advection convective clouds gave light to moderate rains in those regions.Kaneyenhttps://www.blogger.com/profile/06817360454417026229noreply@blogger.comtag:blogger.com,1999:blog-31136724.post-89449366926328899582012-09-21T20:20:40.902+05:302012-09-21T20:20:40.902+05:30 Rajesh sir, today moderate rains were experienc...

But mainland suburbs right beyond Mumbra parsik tunnel to Dombivili/Badlapur/Karjat belt are totally dry with foggy conditions and having Easterly clouds movement more. So Mumbai having westerly clouds and mainland having easterly cloud movement which prouduce any spell only after evening time !
