Kheti Ki Fansi Hui Cycle
Asal mein ho kya raha hai? Garmi badh rahi hai, iska impact seedha kheti par aa raha hai. Crops utna produce nahi kar pa rahe jitna pehle karte the. Ab kisaano ko same output ke liye aur zyada zameen lagani pad rahi hai.
Aur yeh zameen badhane ka matlab hai aur zyada trees kaatna aur farming methods se greenhouse gases release karna. Ek study kehti hai ki ab lagbhag 88 million hectares zameen aur chahiye hogi globally, jis se 22 gigatons CO2 soil mein absorb nahi ho payegi. Rice, maize, wheat jaise main crops se hi sabse zyada emissions ho rahe hain kyunki yeh badi areas mein aur intensive methods se grow hote hain. Yeh cycle sector ko hi climate stress ko aur badhane par majboor kar raha hai.
Garmi Ka Badhta Bill
Is heat ka economic impact bhi kamaal ka hai. Har saal lagbhag 470 billion working hours sirf garmi ki wajah se waste ho jate hain. Kheti mein kaam karne wale toh 35 guna zyada risk par hain heat-related illness se marne ka!
'Heatflation' naam ki ek nayi cheez aa gayi hai. Matlab, garmi se affected foods doosri cheezon se zyada jaldi mehngi ho rahi hain. Examples dekho toh, last 20 saalon mein fruits aur vegetables ke prices 26% badhe hain sirf extreme weather ki wajah se. Coffee toh 100% aur cocoa 160% tak mehnga ho gaya hai pichle ek saal mein sirf adverse weather ke karan!
Experts bol rahe hain ki 2035 tak global food inflation 3 percentage points tak badh sakta hai har saal sirf garmi ki wajah se.
Flash Droughts Aur Kamzoreeb Yields
Aur ek naya problem hai 'flash droughts' ka – yeh aisi sukhdi hai jo bahut tezi se aa jati hai aur crops ko tabah kar deti hai, khaas kar jab woh growth period mein hote hain. Inki wajah se yield loss normal drought se 10% zyada hota hai.
2010 mein Russia mein aisi hi flash drought ne wheat yield 70% tak gira diya tha, jis se global production 20 million metric tons kam ho gayi thi. Us time import karne wale deshon mein poverty aur unrest badh gaya tha.
Waise bhi, har 1°C temperature badhne par wheat ka productivity 4.1% se 6.4% tak kam ho sakta hai, maize 7.5% tak aur soybeans 6.8% tak. 2012 mein US mein corn belt mein heatwave ki wajah se 25% yield kam ho gaya tha.
Sirf yield hi nahi, khane ki quality bhi gir rahi hai. Higher CO2 levels se barley, sorghum aur soy jaisi cheezon mein protein aur nutrients kam ho rahe hain.
Sectors Aur Supply Chains Par Pressure
Beef jaisa meat production long-term climate risks ke liye sabse zyada vulnerable hai. Crop producers ko challenges hain lekin agar woh diversify karein toh demand badh sakti hai.
Coffee, cocoa aur grains jaise commodities ki supply chains ko extreme weather ne disturb kar rakha hai, jis se prices mein bahut utaar-chadhav aa raha hai. Yeh disruptions, inflation ke saath milkar global economies par pressure daal rahe hain aur food insecurity badha rahe hain, khaas kar low-income communities ke liye.
Adaptation Mein Kami Kyun?
'Climate-Smart Agriculture' (CSA) aur regenerative farming ki baat ho rahi hai, jisse productivity badhe, resilience aaye aur emissions kam hon. India mein smallholder farmers ke liye agritech investment badh rahi hai.
Lekin, problem yeh hai ki pichle 50 saalon mein grain production mein extreme heat ke liye koi bada adaptation dikha hi nahi hai; crops abhi bhi utne hi vulnerable hain jitne pehle the. Bade food companies emissions kam karne ke goals bana rahi hain, par implementation abhi bhi limited hai.
Financial institutions bhi piche hain. Zyada tar ko lagta hai climate change unke portfolios ko affect karega, par sirf quarter hi isko apne decisions mein seriously consider kar rahe hain. Yeh inertia khatarnak hai, kyunki productivity loss se fight karne ke liye land expansion jaise steps direct emissions ko badha rahe hain jo aur garmi laa rahe hain.
Aage Ka Raasta: Investment Aur Change Zaroori
Aage badhne ke liye $350 billion tak ka annual investment chahiye hoga 2030 tak global food systems ko climate goals ke hisaab se reshape karne ke liye. Agritech market $200 billion tak pahunch sakta hai 2030 tak, lekin scale, cost aur risk barriers ko hatana bahut zaroori hai.
Is cycle ko todne ke liye humein agricultural efficiency badhani hogi, sustainable practices se emissions kam karne honge, aur asli resilience banani hogi, na ki expansion pe depend karna hoga jo crisis ko aur badha raha hai. Agar yeh shift nahi hua toh agriculture sector ek volatile future face karega, jiske global food security aur economic stability par bade implications honge.
