Agricultural development zones that are designated and managed by the state have diminished by some 126-thousand hectares over the past decade. This is more than 400 times the land mass of Seoul's Yeouido islet.
 
According to related data Democratic Party lawmaker Wi Seong-gon obtained from the Ministry of Agriculture, Food and Rural Affairs, agricultural development zones decreased eleven percent between 2007 and last year from one-point-one million hectares to 993-thousand.
 
By region, port city Busan saw the steepest decrease of 75 percent during the ten year period, followed by Ulsan at 46 percent, Daegu at 31 percent and Gyeonggi Province at 22 percent.
 
On the other hand, farmland that's being diverted for other use is known to be increasing each year, standing at 14-thousand hectares in 2016.
