- Abstract
Precision agriculture (PA) has become increasingly important to farmers particularly in resource-poor and risk-prone settings in the developing world. However, due to cost and technical constraints, deploying PA infrastructure as decision support systems (DSSs) in smallholder farming settings is often hindered. This paper draws on freely available satellite data (Sentinel-2A) and software (SNAP Toolbox), within the framework of open source remote sensing (OSRS) to demonstrate the potential of monitoring crop health and development towards building an effective DSS to inform farm management and resource allocation decision making using the Tono Irrigation Scheme—a resource-poor rural irrigation system in Ghana, as a case study. We find that vegetation index algorithms in SNAP Toolbox can accurately identify biophysical and growth conditions of crops including chlorophyll content, nitrogen status, pest and disease infestation, and water requirements. Despite the potential inherent in this novel cost-effective OSRS-based monitoring system, basic training of scheme managers and extension officers is required to enable them interpret output from OSRS analysis. Given the potential to reduce costs, improve allocation of scarce resources and increase yields, it is worth implementing OSRS as a DSS for smallholder farmers in other resource-poor settings.
