The Lockyer Valley: The Salad Bowl That Feeds Southeast Queensland

The Lockyer Valley, the fertile agricultural valley that descends from the foot of the Toowoomba Range east toward Ipswich and the Brisbane Valley and that the alluvial soils, the reliable groundwater from the Lockyer Valley Groundwater System, and the temperate climate between the coastal humidity and the inland dryness create as one of the most productive intensive vegetable growing regions in Australia, provides southeast Queensland with the fresh vegetables and the salad crops that the Brisbane and the Gold Coast markets consume in the quantities that the proximity and the production quality of the Lockyer Valley supply chain create as the competitive advantage that the local production maintains against the more distant growing regions that the freight cost disadvantage reduces to the off-season supplies when the local production seasonally ceases. The valley's vegetable farms, concentrated around the towns of Gatton, Laidley, and Forest Hill, produce the lettuces, the brassicas, the beans, and the Asian greens that the multicultural food retail market and the institutional catering that the schools, hospitals, and the food service industry require in the fresh supply chain that the short freight distance from the Lockyer Valley to the Brisbane markets sustains.

The irrigation infrastructure of the Lockyer Valley, the network of the bores, the irrigation channels, and the dam water storages that the intensive vegetable production requires for the water application that the short-season crops need for the germination, the establishment, and the rapid growth that the marketing window demands, represents the significant agricultural capital investment that the Lockyer Valley farming families and the corporate farming operations have made in the water infrastructure that sustains the production intensity and the year-round supply capability that the wholesale market and the supermarket retail buyers require for the supply reliability that the retail contract demands. The groundwater management of the Lockyer Valley Groundwater Management Area, regulated by the Queensland Government to ensure the sustainable extraction that the long-term viability of the irrigated agriculture requires against the short-term extraction pressure that the individual farm's production maximisation creates, is the critical regulatory framework that the sustainable agricultural future of the valley depends on for the water resource management that prevents the aquifer depletion that the unregulated extraction would create.

The multicultural farming community of the Lockyer Valley, including the Vietnamese, the Chinese, and the Korean farming families who have established in the valley through the horticultural migration that the agricultural labor shortage and the market for the Asian vegetable varieties in the multicultural Brisbane and the Gold Coast markets has created over the past 30 years, contributes the cultural diversity and the specialist knowledge of the Asian vegetable varieties that the mainstream supermarket and the Asian grocery retail market demand. The Vietnamese and the Korean vegetable growers' contribution to the supply of the Asian greens, the bitter melon, and the specialty herbs that the Asian food culture demands creates the market supply that the multicultural consumer accesses in the fresh Asian food retail that the Lockyer Valley production sustains.

The Gatton Research Station of the University of Queensland, the agricultural research facility at Gatton that the UQ's School of Agriculture and Food Sciences operates for the crop science, the horticulture, and the soil science research programs that the intensive vegetable growing context creates the research questions for, provides the agricultural science capability in the heart of the Lockyer Valley that the research-to-practice pipeline connects to the farming operations that implement the improved varieties, the pest management, and the irrigation efficiency that the research develops for the production conditions that the Lockyer Valley's farming systems create. The extension connection between the university research and the commercial farming operations that the Lockyer Valley's farming community sustains through the extension programs and the demonstration farm activities that the research station operates, creates the knowledge transfer pathway that sustains the agronomic improvement that the competitive vegetable production market demands from the Lockyer Valley growers.
