Item Restricted Spatio-temporal dynamics of water quality and land use in the Lake Dianchi (China) system: a multi-source data-driven approach(Elsevier, 2025-06)Study region: Lake Dianchi, China. Study focus: Urbanization and land development increasingly challenge water quality, yet their interactions remain unclear. This study examines these interactions in Lake Dianchi by developing an empirical water quality inversion model. Multi-year water quality data from monitoring stations were integrated with Landsat 8 L2 data to analyze seven key Water Quality Parameters (WQPs): TP, Hg, Cd, As, Zn, S, and NH₃-N. Land use was assessed using a multi-dimensional framework incorporating weighted overlays of multi-source data. The relationships between land use and water quality were analyzed using Spearman correlation, redundancy analysis (RDA), and the Optimal Parameter Geodetector (OPGD). New hydrological insights for the region: From 2014–2022, pollutant concentrations declined, yet TP pollution remains severe, keeping the lake classified as Class V. Pollution was more concentrated in Caohai than Waihai, highlighting point-source pollution. Land use changes were dominated by “urban expansion” and the “returning farmland to forest” program. RDA results indicated that construction (positive) and farmland (negative) were the primary drivers of WPI. OPGD analysis showed that FACI∩CACI was the strongest explanatory factor for WPI. Over time, land use influence on WPI weakened due to urban saturation, environmental policies, and delayed water quality responses. These findings quantify land use-water quality interactions and provide insights for managing urban plateau lakes amid rapid development.Item Restricted Analysis of quality safety of agro-products influenced by farmers’ production behaviors(Canadian Center of Science and Education, 2011-09)Farmers’ production behaviors were important factors which caused quality safety problems of agro-products. Based on the survey in parts of four provinces of Sichuan, Gansu, Henan and Hubei, from the perspective of behaviors of production information acquisition and decision-making behaviors of material inputs, this paper analyzed quality safety of agro-products influenced by farmers’ production behaviors in production process. After the analysis, this paper discussed the countermeasures that could guarantee the quality safety of agro-products.Item Restricted Agriculture Mechanization for Sustainable DevelopmentThis presentation highlights the vital role of agricultural mechanization in promoting sustainable agricultural and rural development in Asia. With increasing labor scarcity and rising rural wages, mechanization offers timely, efficient, and scalable solutions to address farm labor shortages while enhancing productivity, reducing drudgery, and supporting the expansion of farm operations. Drawing on recent empirical studies, the presentation demonstrates how mechanization improves crop yields—especially in rice, wheat, and maize—through enhanced land preparation, pesticide application, and irrigation efficiency. Mechanization also contributes to increased land productivity and mitigates cropland abandonment in rural China. Beyond production benefits, evidence reveals that mechanization facilitates non-farm employment, particularly among rural women, thus improving household welfare, income diversification, and social outcomes. The presentation introduces a forthcoming special issue and two edited volumes that synthesize regional insights from Bangladesh, China, India, Indonesia, and Nepal, providing nuanced analysis of mechanization’s impacts on smallholder farming, gender, and policy innovation. Together, these findings underscore the need for inclusive, context-sensitive policies to harness mechanization for resilient and equitable food systems.Publication Metadata only Certified pasture seeds(Christchurch [N.Z.] : Canterbury Chamber of Commerce, 1937-10)The Agricultural Bulletin was produced monthly from 1929, the last issue held by Lincoln University being issue 467, published in 1968.
