Delhi ki problems ko log aksar surface level par dekhte hain. Traffic, vehicles, factories, population. Ye sab visible reasons hain. Lekin Delhi ka environment sirf shehar ke andar ki activities se control nahi hota. Iske peeche ek bada geographical factor hai jiska naam aksar discussion se gayab rehta hai: Aravalli Hills.
Aravalli Hills Delhi NCR ke liye ek silent shield ki tarah kaam karti rahi hain. Ye shield dikhta nahi, isliye log iski value nahi samajhte. Lekin agar ye shield dheere dheere khatam hota gaya, to Delhi ka future sirf “thoda zyada polluted” nahi hoga, balki structurally unstable ho jayega.
Sabse pehla impact dust aur air quality par padega. Western Rajasthan ki taraf se aane wali dry winds aur desert dust ko Aravalli range partially rok kar rakhti hai. Jab ye pahadi aur inka forest cover weak hota hai, to dust storms ko koi natural barrier nahi milta. Result ye hota hai ki particulate matter seedha Delhi NCR me enter karta hai. Is situation me air pollution ka blame sirf vehicles par dalna incomplete analysis hai. Geography yahan direct role play karti hai.
Doosra bada impact temperature aur heatwaves par hota hai. Aravalli region ka green cover heat absorption aur moisture retention me madad karta hai. Jab pahadiyon ko cut kiya jata hai ya vegetation destroy hoti hai, to surface temperature badhta hai. Ye heat plains ki taraf radiate hoti hai, jiska effect Delhi jaise concrete-heavy city me aur zyada extreme ho jata hai. Isliye Delhi me har saal garmi ke naye records ban rahe hain. Ye sirf climate change ka result nahi, balki local landform damage ka outcome bhi hai.
Paani ka issue aur bhi serious hai. Aravalli Hills natural groundwater recharge zones ka kaam karti hain. Rainwater pahadiyon me seep hota hai aur dheere dheere aquifers ko bharta hai. South Delhi, Gurgaon aur Faridabad jaise areas ka groundwater system isi recharge par depend karta hai. Jab mining aur construction ke liye pahadiyon ko blast kiya jata hai, to ye recharge mechanism toot jata hai. Phir shehar tanker water par dependent ho jata hai. Ye dependency short-term nahi hoti, ye permanent trap ban jati hai.
Flood aur waterlogging ka contradiction bhi isi breakdown ka result hai. Ek taraf Delhi pani ke liye tarasti hai, doosri taraf thodi si heavy rain me roads doob jati hain. Ye isliye hota hai kyunki Aravalli ke natural drainage channels disturb ho chuke hain. Pani ko absorb aur channelize karne wali landform jab kaam nahi karti, to pani ya to surface par jam jata hai ya seedha runoff ban kar waste ho jata hai.
Wildlife aur ecosystem ka collapse bhi Delhi ke liye warning sign hai. Aravalli forests me leopards aur other wildlife ka presence sirf news headlines ke liye nahi hai. Ye indicate karta hai ki ecosystem pressure me hai. Jab natural habitats shrink hote hain, to animals urban boundaries ki taraf move karte hain. Ye sirf human-wildlife conflict ka issue nahi, balki ecological imbalance ka signal hai. Is imbalance ka long-term effect insects, soil quality aur vegetation cycle par padta hai, jo indirectly climate ko aur unstable karta hai.
Mining Aravalli ke liye sabse destructive factor raha hai. Legal aur illegal mining ne pahadiyon ka natural structure tod diya hai. Ek baar pahadi ka rock structure aur soil layer disturb ho jaye, to use natural state me wapas lana practically impossible hota hai. Plantation drives is damage ka cosmetic cover ho sakti hain, solution nahi. Delhi ke perspective se iska matlab ye hai ki shehar ka natural defense system irreversible damage face kar raha hai.
Urban expansion ne is process ko aur tez kar diya hai. Farmhouses, luxury housing aur road projects Aravalli ke buffer zones me ghus chuke hain. Isse natural corridors block ho rahe hain. Jab land sirf real estate ke lens se dekhi jati hai, to uska ecological role ignore ho jata hai. Delhi jaise megacity ke liye ye approach long-term suicide jaisi hai.
Agar Aravalli Hills isi tarah degrade hoti rahi, to Delhi ka future ek high-maintenance city ban kar reh jayega. Zyada AC usage, zyada water imports, zyada health issues aur zyada infrastructure stress. Ye sab cheezein already dikh rahi hain. Difference sirf scale ka hai. Aaj problem manageable lag rahi hai, kal ye unmanageable ho sakti hai.
Ye samajhna zaroori hai ki Aravalli Hills ka issue environmental activism ka topic nahi hai. Ye urban survival ka question hai. Delhi ka growth model tab tak sustainable nahi ho sakta jab tak uske surrounding natural systems intact na rahein. Aravalli ka khatam hona sirf pahadiyon ka loss nahi hoga, balki Delhi ke climate balance ka collapse hoga.
Simple shabdon me bolein to agar Aravalli Hills weak hoti gayi, to Delhi ek aisi city ban jayegi jahan rehna aur mehenga, aur mushkil hota chala jayega. Nature ke jo systems free me kaam kar rahe hain, unka replacement kisi technology se possible nahi hai. Isliye Aravalli ka bachna Delhi ke bachne se directly linked hai.
