Abstract

Crop diversification strategies are one way for Kenyan households to improve their food security. In Kirinyaga Central and East Sub-Counties, the agricultural sector is dominated by smallholder coffee farmers who suffer seasonal hunger due to low food crop productivity. This has led to what has been labeled as ‘lean months’ by scientists. Several studies have shown that crop diversification provides smallholder farmers with food and nutrition security. However, smallholder coffee farmers in the study area have minimal information concerning potential and contribution of crop diversification to food security. The study aimed to establish the effects of crop diversification on food security in Kirinyaga Central and East Sub-Counties, Kirinyaga County, Kenya. The study was guided by modern portfolio theory. The study was carried out in three agro-ecological zones (UM1, UM2 and UM3) using descriptive research design to collect household data with structured questionnaires. A target population of 18420 smallholder coffee farmers was used, from which using multistage sampling techniques, a sample of 408 was selected. Descriptive statistics and econometric models were relied on for data analysis. The mean Crop Diversification Index (CDI) was 0.39. Cereals were the most consumed food crop with mean Food Consumption Score (FCS) of 7.50. The total mean FCS of households was 27.46, which may have implied that majority of them fall into borderline food consumption category (52.87%). Further, the findings show that farmers faced seasonal food insecurity with 54.36% of them reporting at least one month of food scarcity. Findings of multinomial logistic model revealed that the expected change in probability for a farmer to fall into borderline FCS level at p<0.05, was effected by landscape heterogeneity (33.2%), crop varietal diversity (8.8%), intercropping (13.6%) and crop species diversity (15.2%). For a farmer to fall in acceptable FCS level at p<0.05, it was contributed by 0.5% of landscape heterogeneity, crop rotation (0.4%), crop varietal diversity (0.4%), intercropping (2%) and crop species diversity (1.8%). Based on this study findings, we can conclude that crop diversification is one viable option in smallholder farming that can ensure establishment of resilient agricultural systems that can contribute significantly to household food security. There is need for government to support policies and programs that promote adoption of crop diversification strategies for realization of enhanced food and nutrition security.

The study was carried out in three agro-ecological zones (UM1, UM2 and UM3) using descriptive research design to collect household data with structured questionnaires. A target population of 18420 smallholder coffee farmers was used, from which using multistage sampling techniques, a sample of 408 was selected.

Cereals were the most consumed food crop with mean Food Consumption Score (FCS) of 7.50. The total mean FCS of households was 27.46, which may have implied that majority of them fall into borderline food consumption category (52.87%).

Findings of multinomial logistic model revealed that the expected change in probability for a farmer to fall into borderline FCS level at p<0.05, was effected by landscape heterogeneity (33.2%), crop varietal diversity (8.8%), intercropping (13.6%) and crop species diversity (15.2%). For a farmer to fall in acceptable FCS level at p<0.05, it was contributed by 0.5% of landscape heterogeneity, crop rotation (0.4%), crop varietal diversity (0.4%), intercropping (2%) and crop species diversity (1.8%).

    AB  - Crop diversification strategies are one way for Kenyan households to improve their food security. In Kirinyaga Central and East Sub-Counties, the agricultural sector is dominated by smallholder coffee farmers who suffer seasonal hunger due to low food crop productivity. This has led to what has been labeled as ‘lean months’ by scientists. Several studies have shown that crop diversification provides smallholder farmers with food and nutrition security. However, smallholder coffee farmers in the study area have minimal information concerning potential and contribution of crop diversification to food security. The study aimed to establish the effects of crop diversification on food security in Kirinyaga Central and East Sub-Counties, Kirinyaga County, Kenya. The study was guided by modern portfolio theory. The study was carried out in three agro-ecological zones (UM1, UM2 and UM3) using descriptive research design to collect household data with structured questionnaires. A target population of 18420 smallholder coffee farmers was used, from which using multistage sampling techniques, a sample of 408 was selected. Descriptive statistics and econometric models were relied on for data analysis. The mean Crop Diversification Index (CDI) was 0.39. Cereals were the most consumed food crop with mean Food Consumption Score (FCS) of 7.50.
