Cli­mate change

Re­cent cli­matic changes show that our cur­rent agri­cul­tural prac­tices need to be changed with the in­crease in day tem­per­a­ture. For ex­am­ple, if there is a rise of two-three de­gree Cel­sius in the day tem­per­a­ture then in­stead of wa­ter­ing the plants ev­ery 21 days, wa­ter­ing at ev­ery 15 days will prove to be a bet­ter op­tion, in or­der to min­i­mize the heat ef­fect on the yield of the crop.

How­ever, the best op­tion re­mains the cul­ti­va­tion of tem­per­a­ture tol­er­ant va­ri­eties of plants un­der these cir­cum­stances. Though the sit­u­a­tion is not much se­ri­ous now a days, but the things many turn out to be cu­mu­la­tive and very se­vere if we do not take ap­pro­pri­ate mea­sures to com­bat this change in the cli­matic con­di­tions and to min­i­mize its ef­fect of the agri­cul­ture pro­duc­tion.

On the avail­able pre­vi­ous data­base of the tem­per­a­ture changes, in par­tic­u­lar peak tem­per­a­ture dur­ing the day, and cur­rent year tem­per­a­ture, gov­ern­ment can look for­ward to take ap­pro­pri­ate sug­ges­tive or ex­ec­u­tive mea­sures. I think this step will be in a di­rec­tion to at least sus­tain if not in­crease cur­rent crop pro­duc­tion. —Rawalpindi

Cli­mate change is a se­ri­ous global is­sue: its im­pacts are badly ef­fect­ing hu­man lives around the world these days. Pak­istan is among the top 10 coun­tries where the global warm­ing is at the risky level. Last year, about 1200 peo­ple died due to heat wave. De­for­esta­tion, melt­ing glaciers, rise in the sea level and rapid ur­ban­iza­tion are at­tribut­ing cli­mate changes. Ex­perts es­ti­mate, if cli­mate change is not taken se­ri­ously, the re­sult will be unimag­in­able. Pre­dictably, within the du­ra­tion of 35 to 45 years, the Karachi city can drown.

Tree plan­ta­tion can be help­ful in re­duc­ing the ef­fects of the global warm­ing since trees act as nat­u­ral fence to pro­tect against floods and tsunamis. Pak­istan is one of the low for­est cov­ered coun­tries only with five per cent for­est area. In or­der to make the life pos­si­ble on the earth, we must work col­lec­tively to re­duce the use of af­fect­ing agents that cause global warm­ing. — Via email
