Ecological intensification has been proposed as a promising lever for a transition towards more sustainable food systems. Various food systems exist that are based on ecological intensification and may have potential for a sustainability transition. Little is known, however, about their diversity and about how they perform against dominant systems in terms of the multiple societal goals. The aim of this study is to contribute to knowledge about sustainability transitions in food systems through an empirical analysis of vegetable food systems in Chile. The study (i) characterizes the diversity of vegetable food systems in Chile (ii) evaluates the food systems in terms of multiple societal goals, and (iii) assesses their potential for supporting sustainability transition pathways from the perspective of ecological intensification. Results indicate that among the five vegetable food system types, the agroecological and the small organic have potential to foster a sustainability transition. Nevertheless, these systems are small and localized, and scaling them requires actions to remove barriers in the relations with the agri-food regime and among themselves. The broader relevance of this analysis is that there needs to be awareness in research on transitions about the diversity of food systems present in countries and how they interact.

“…Maize (Zea mays L.), also called Indian corn, is the third most important cereal crop in the world after wheat and rice (Choudhary & Kumar, 2013) since it represents 34% of total global cereal production (FAOSTAT, 2014). It originated in southern Mexico (Matsuoka et al, 2002) and spread across the Americas and subsequently to Europe, Africa and Asia (Rótolo et al, 2015). Maize belongs to the Poaceae family and is primarily a cross pollinated species, a feature that has contributed towards its broad morphological variability and geographical adaptability (Ishaq et al, 2015).…”

Current analysis investigates genotype x environment interaction and stability performance of grain yield with nine maize genotypes in seven environments. ANOVA revealed highly significant (p-value<0.001) data for genotypes, environments and their interactions. Only PC1 (45.4%) and PC2 (35%) were significant (p ≤ 0.05). Genotype G7 had a specific adaptation to environment E7, whereas genotypes G2 and G3 were adapted to environment E1, and genotypes G8 and G9 to environment E5. Dataset was divided into group A, composed of E5 and E7, and group B composed of E1, E2, E3 and E6. Genotypes G1, G2, G3 and G6, belonging to group B, were the most productive. Further, no environment fell into the G4, G5, G7, G8 and G9 sectors, denoting these genotypes as the poorest ones across environments. GGE biplot indicated that genotype G4 was highly unstable, whereas G3 very stable. In addition, G2 was more desirable due to its small contribution to both G and GE. On the other hand, G4 and G9 were more undesirable due to large contribution to either G or GE. Finally, genotypes G2 and G9 were very different. Their dissimilarity may be due to difference in mean yield and/or in GEI.

“…Previous studies have not unpacked the annually alternating maize seed cultivation regime. However, there is a close connection between market factors and seed selection (Waldman et al 2016;Rótolo et al 2015;Swanckaert 2012), it is suggested that market factors have affected the local maize production in Son La. In this study, we thoroughly investigate the causes for the alternating seed cultivation regime and its consequences.…”

“…What seeds should be adopted by farmers is an ambiguous and tricky matter to decide since it is often related to social norms, local characteristics, and the availability of information on the quality and support for seeds (Waldman et al 2016;Coomes et al 2015). According to Rótolo et al (2015), seed selection is also greatly affected by market competition. The interaction between seed enterprises might lead to the manipulation of seeds supply.…”

Influence of Trading Structure on Maize Seed Selection by Farmers in Vietnam: Case Study on Yen Chau District, Son La Province

Maize is the most important cash crop in Vietnam's northern mountainous region. It is credited with eradicating hunger and alleviating poverty. However, the continuous decreasing trend in the global maize price since 2013 has resulted in various socioeconomic problems. Yen Chau district follows a cultivation regime of annually changing maize varieties. This goes against the objectives of national test procedures for new seed. This study aimed to establish whether the annually changing seed cultivation regime is the consequence of the fierce competition between seed enterprises. We found that the maize trading structure is centered on a three-level trader network that plays a crucial role in connecting stakeholders. Strong social relationships along with weak credit/production commitments between farmers and traders have facilitated maize production throughout the region. Seed and supply enterprises target traders to promote their products and are the most important information channel for farmers. This study's findings suggest that seed selection in Yen Chau has no scientific basis but is the result of market factors.
