| 概要 |
Rice production in Agusan del Norte is critical for food security but generates substantial waste streams with potential environmental impacts. This study analyzes pesticide and fertilizer runoff in m...ajor rice-growing areas using satellite imagery, Geographic Information Systems (GIS), and field surveys. The study identifies critical risk zones by overlaying geospatial data with thematic layers, such as elevation, slope, soil drainage, and proximity to irrigation channels. Results show that poorly drained soil and low-lying areas near irrigation channels are prone to waste accumulation, leading to water contamination and soil degradation. Agricultural input usage varies: Butuan City relies on chemical inputs, Cabadbaran City uses minimal synthetic inputs, and Remedios T. Romualdez applies balanced methods. Proposed solutions include riparian buffer zones, improved drainage systems, and integrated pest management to reduce environmental impact. The study highlights the role of geospatial analytics in enhancing agricultural waste management and fostering sustainability in rice production.続きを見る
