GLOBAL WARMING AND ITS IMPACT ON CANE PRODUCTION UNDER PAKISTAN CONDITIONS

According to Moorthy etal (2012) the temperature and precipitation trends did not have measurable impact on cotton, rice, sorghum and wheat, however cane yields were improved by 1%, over last 60 years (1951-2010).

Description
Summary:According to Moorthy etal (2012) the temperature and precipitation trends did not have measurable impact on cotton, rice, sorghum and wheat, however cane yields were improved by 1%, over last 60 years (1951-2010). Besides the overall changes already quoted, annual variation in temperature and rainfall are different in different regions of Pakistan (Table-1). The Sugarcane crop grown under rain fed conditions would have different response to climate change than the crop grown in irrigated or partially irrigated conditions. [...]cane crop in Zimbabwe, Brazil and some African countries would be more affected than that in Asian countries. CONCLUSION Pakistan is vulnerable to global warming problems affecting sugarcane production. Besides their specific effect causing torrential rains, floods and overall drought, Increasing temperature cause higher evapo-transpiration and the crop is subject to severe moisture stress and is liable to demand more water.
