Socio-economic and Environmental Analysis of Organic Market Gardening of Certified Bio Participatory Guarantee System in the Province of Kadiogo in Burkina Faso

Conventional gardening leads to major negative effects such as soil degradation, water pollution, biodiversity loss, and health risks for the population. Face to those challenges, organic vegetable farming certified by the Participatory Guarantee System (Bio-PGS) is emerging as a sustainable alternative. This study explores its socio-economic and environmental impacts in urban, peri-urban, and rural areas of the Kadiogo province of Burkina Faso. Data was collected by survey from 20 key informants and 102 Bio-PGS producers. Descriptive analysis and statistical tests (Chi-Square and Fisher) has been applied. In peri-urban, rural, and urban areas, women represent 100%, 76.47%, and 96.83% of producers, respectively. Yields declining, high cost of chemical inputs, and distribution network encourage producers to adopt market gardening of certified bio participatory guarantee system. For biopesticides chili pepper, garlic, and papaya leaf mixture was the most commonly used in urban (60%), rural (12%) and peri urban (19%) areas. As for bio-fertilizers compost (63%) were mostly used in urban areas, Bokassi and compost (17%) in rural areas and Bokassi (21%) in peri-urban areas. Resource-saving practices were reported by 100% of producers in peri-urban areas, 94.12% in rural areas and 46.03% in urban areas. There was a significant difference at the 1% level between peri-urban and urban areas (p < 0.0001) and between rural and urban areas (p = 0.0014). Intercropping was practiced by all farmers in peri-urban areas, 30.77% in rural areas and 63.41% in urban areas. There was a significant difference between the proportions in peri-urban and rural areas (p < 0.0001) and between peri-urban and urban areas (p = 0.0015). Repellant plants were used by 22.77% of producers in peri-urban areas, 100% in rural areas and 78.05% in urban areas. There was a significant difference at the 1% level between the proportions in peri-urban and rural areas (p = 0.0003) and between peri-urban and urban areas (p = 0.0116). Individual producers (98.89%), producers with market access (66.67%), of producers who are members of an association (100%) and Amaranthus producers (96.47%) had an income between 0 and 500,000 CFA francs, with a significant difference compared to those with an income above 500,000 CFA francs. For maximizing Bio-PGS potential, additional efforts are needed, particularly in terms of institutional support and consumer awareness.
