Land fragmentation is a common agricultural phenomenon in many countries where a single largefarm is subdivided into a large number of separate small land plots. This paper is based on a studythat was carried out to evaluate the impact of land fragmentation on food security in three agroecologicalzones (AEZs) of Embu County in Kenya from January to November 2016. The studyused data collected from 384 farm-households that were randomly selected from three AEZs in theEmbu County, using the 4-stage cluster sampling method. The AEZs were the Sunflower-CottonZone, the Coffee Zone and the Tea Zone, based on the official AEZs classification system in Kenya.Household caloric acquisition method was used to compute a household food security index (HFSI)that was used to measure the household food security status. The effect of farm size on foodsecurity was evaluated using the Binary Logit Regression method. The results showed that theaverage number of people in a household was 3.73 in the Tea Zone, 3.59 in the Coffee Zone and3.93 in the Sunflower Zone, and that farm size had a positive and significant effect on food securityin the Sunflower (P=.029) and Tea zones (P=.007), but not in the Coffee Zone (P=.365). Further, itwas found that the minimum farm-size that could ensure the attainment of the minimum (cut-off)point for household food security (HFSI = 1) was above 2 ha in the Sunflower Zone and 0.5 ha inthe Tea Zone. Based on the study findings, it is recommended that further fragmentation of farmsbelow 0.5 ha in the Coffee and Tea zones and 2 ha in the Sunflower Zone should be discouraged toensure sustainable food security in the study area. For the farms that are already below theminimum cut-off size for food security, measures to increase these farms’ productivities so that theycan support more people per ha should be devised and implemented.
