    Effects of land fragmentation on farm efficiency in three agro-ecological zones of Embu County in Kenya
    (Academic Journals, 2021) Ndirangu, Samuel Njiri
    This paper is based on a study that was carried out to evaluate the effect of land fragmentation on farm efficiency in three agro-ecological zones of Embu County in Kenya from July 2017 to March 2018. The study used data collected from 384 farm-households that were randomly selected from three agro-ecological zones (AEZs) in the Embu County, using the multistage stratified sampling method. The AEZs were the Sunflower-Cotton Zone, the Coffee Zone and the Tea Zone, based on the official classification system in Kenya. Farm technical efficiency was measured using non-parametric data envelopment analysis. The multinomial regression analysis was used to evaluate the effect of farm size and other factors on farm efficiency. Farm size was found to have a negative and significant effect on farm efficiency in the Coffee Zone (p=0.013, β=0.879) and Tea Zone (p=0.046, β=1.016), but was insignificant in the Sunflower-Cotton Zone. However, the study revealed that the impact of farm size on farm efficiency varies within and across different agro-ecological zones. Other key factors that were found to significantly affect farm efficiency in combination with farm size are distance to market outlet, household head’s level of education and age and farm access to credit and irrigation water. Similarly, the impact of these factors was found to vary in and across the three zones. For improvement of farm efficiency in the study area, this study recommends that the remaining large farms in the Tea Zone be managed as smaller semi-autonomous blocks. Other recommendations made were increasing access to agricultural education, markets, credit and irrigation water. Key words: Land fragmentation, farm size, agro-ecological zones, technical efficiency, mixed farming.

    Effects of Land Fragmentation on Food Security in Three Agro-ecological Zones of Embu County in Kenya
    (Asian Journal of Agricultural Extension, Economics & Sociology, 2017) Ndirangu, Samuel N.; Mbogoh, Stephen G.; Mbatia, O. L. E.
    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.
