The Future Holds Challenges and Opportunities for Dairy Producers
In the future, global food production systems will come under increased pressure from population growth, urbanization, and climate change. Over the last two years, scientists from the United States, the United Kingdom, and Sweden have examined projections and current data to identify ways in which the dairy industry may respond to these challenges to meet increased demand for dairy products over the next half century. A new review published in the Journal of Dairy Science® projects how dairy producers will meet these challenges and take advantage of opportunities in 2067 and beyond.
Global population is expected to increase from 7.6 to 10.5 billion people by 2067, while arable land per capita will decrease by 25 percent. Because population growth will be uneven, disparity in arable land per capita is also expected to increase. With increased population density comes increased urbanization, which has typically led to greater personal income and greater demand for dairy products. It is also expected that climate change will force changes in the location of dairy production. In the Northern Hemisphere, where 86 percent of the world's milk is produced, the effects of climate change are less tempered by oceanic effects. Dairy production will shift to areas with more sustainable water supplies and adequate growing seasons in response to changes in climate.
To meet increased demand in the face of these challenges will require dairy farms to be profitable and sustainable. "Dairy farmers in 2067 will meet the world's needs for essential nutrients by adopting technologies and practices that provide improved cow health and longevity, profitable dairy farms, and sustainable agriculture," said Jack H. Britt, PhD, professor and associate dean emeritus from North Carolina State University, Raleigh, NC, USA. The authors forecast that dairy farmers will adopt ways of managing the microbiomes of cows' digestive systems and other body systems to improve health and well-being. They also believe that there will be more attention to managing a cow's epigenome, which mediates longer-term responses to the environment.
