Mumbai: India, world’s largest milk producer, may see a loss of milk production by over 3 million tonnes (MT) per year by 2020 due to frequent climate change and it may also lead to a decline in per capita consumption, industry experts said.
The country’s milk production has been steadily increasing with 2015-16 recording an output of 160 MT, the impact of rising temperatures, especially on cross-bred cows will make the task of meeting domestic demand difficult and could eventually lead to a decline in per capita consumption, industry experts said at the 45th Dairy Industry Conference, organised by Indian Dairy Association (West Zone) in Mumbai.

“The dairy sector is likely to be affected both directly and indirectly by climate change. While stress to animals caused by changes in temperature-humidity index would directly affect milk production, indirect effects include feed and water availability being impacted by adverse climate events," National Dairy Development Board (NDDB) chairman Dilip Rath said.
Heat stress also impacts animal reproduction adversely as levels of above the acceptable levels can impact conception rates. Research indicates that stress from heat can cause decline in milk yield in the range of 10 to 30% in first lactation and 5-20% in second and third lactation and both the heat waves and cold waves can cause short to long term cumulative heat effect on milk production in cattle and buffaloes, he said.
“As climate change is a challenge that impacts all of us, our dairy sector must not only evolve adaptation strategies but also help in mitigation by contributing to reduction in greenhouse gas emissions from the dairy sector," he added.
