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
