Soil degradation to affect food production
Amidst the growing world population, the more frequent utilization of soil for food production is also seen to degrade soil quality, a soil scientist said.
Rattan Lal, soil scientist from Carbon Management and Sequestration Center in Ohio State University, said that soil is prone to degradation by natural factors through the effects of climate change and man-made factors such as land misuse and soil mismanagement. One way of addressing this problem is producing more from less.
“Sustainable intensification, it is a strategy to produce more from less by reducing losses and increasing soil, water, and nutrient use efficiency,” Lal said during his recent visit at Philippine Rice Research Institute (PhilRice).
“The key is to produce more food from less land, per drop of water, per unit input of fertilizers and pesticides, per unit of energy, and per unit of Carbon emission,” he added.
He then cited some technological innovations for researchers and policy-makers to follow and promote until 2050 such as soil-less agriculture, precision farming, soil restoration, nutrition-sensitive agriculture, urban/sky farming, and space farming.
