Integrating ArcGIS and CROPWAT 8.0: A computer science approach to onion crop water requirement validation

Abstract

This paper explores the integration of ArcGIS and CROPWAT 8.0 for validating and optimizing the water requirements of onion crops, with an emphasis on the computer science approach to irrigation scheduling. Water management plays a crucial role in agricultural productivity, particularly for water-intensive crops like onions. ArcGIS provides spatial data analysis, while CROPWAT 8.0 simulates crop water requirements. By integrating these two tools, the paper aims to improve irrigation practices, reduce water wastage, and optimize crop yields. The integration method involves geospatial mapping, data collection, water requirement modeling, validation, and optimization. Additionally, the paper outlines the benefits of using ArcGIS and CROPWAT 8.0 for decision support systems in real-time water management. The integration offers accurate, region-specific, and environmentally sustainable water management strategies for onion cultivation, addressing the growing demand for efficient irrigation practices in the face of climate change.
