The Spatial Distribution and Impacts of Organic Certificates in Southwest China

Abstract

Organic farming is a good choice for agricultural development in southwest China under the trade-off between environmental protection and agricultural development. However, no researcher has investigated the current state and development of organic agriculture in southwest China. As a result, this paper explored the spatial structure of organic agriculture in southwest China by examining the distribution of organic certificates, as well as the environmental and socioeconomic impacts. The results show a dramatically uneven distribution of certified organics among different provinces, cities, and organic certificate types. On the province scale, Guizhou has the highest number (1174) and density (73.40 per 1010 m2) of organic certificates. On the city scale, Zunyi and Chengdu have the highest densities (218.77 and 342.52 per 1010 m2, respectively). Most of the certified organics are plants, accounting for 76.95%. The spatial distribution of organic farming is influenced by the interaction of several factors, including precipitation, temperature, GDP, highway density, gross agriculture output, agriculture machinery, and rural employed persons. However, the related and determinant factors of organic certificate distribution vary greatly across different regions, spatial scales, economic development levels, and agricultural development statuses. For the entirety of southwestern China, the factors significantly related to the distribution of organic certificates are GDP, highway density, gross agriculture output, agriculture machinery, and rural employed persons. However, these factors are GDP, gross agriculture output, agriculture machinery, and rural employed persons for Sichuan, and gross agriculture output and rural employed persons for Guizhou. Factors constraining the development of organic agriculture in regions with better economic and agricultural conditions are much fewer than in poorer regions. All of the nine selected variables, except global radiation, are significantly related to organic certificate distribution in regions with better economic conditions, while none of them had a significant correlation with organic certificate distribution in poorer regions. Furthermore, climate is no longer a constraint in regions with better agricultural conditions. These findings are of great significance for the development and research of organic agriculture in southwest China. The development of organic agriculture in southwest China requires consideration of both the combination of multiple factors and the stage of regional economic and agricultural development.
