Impact of Climate Change on Agriculture
- Every crop has a temperature range for its vegetative and reproductive growth.
- When the temperature falls below the range or exceeds the upper limit then crop production faces constraints.
- A study found that 10 C increase in maximum temperature at vegetative, reproductive, and ripening stages there was a decrease in Aman rice production by 2.94, 53.06, and 17.28 tons respectively (Islam, 2008).
- With the change in temperature (by 20C and 40C the prospects of growing wheat and potatoes would be severely impaired. Production loss may exceed 60% of the achievable yields (Karim, 1993).
