Hybrid Energy Powered Smart Irrigation System for Smallholder Farmers: Installation Site and Crop Selection

Abstract

In the context of food-energy-water nexus and uncertainties in climate change, hybrid energy powered smart irrigation system (HEPSIS) is an emerging solution for optimizing both energy and water to boost crop yield. In Pakistan, most of the farmers especially smallholder farmers are currently relying on conventional irrigation practices which result in high water consumptions, high energy consumptions (by means of pumping), low crop yields, and net profit. Prior to design/development, installation, and testing of the HEPSIS, it is essential to know a suitable site and potential food/cash crops which will be irrigated. In this regard, the study aims to select installation site and potential crops. Site suitability is explored for Sindh province from viewpoints of Indus Basin Irrigation System mapping, groundwater table depth/quality mapping, land use land cover, and soil classifications. Furthermore, crop selection analyses are performed by means of a screening matrix approach based on stars to identify two potential food and cash crops. As per the results, Badin, Ghotki, Khairpur, Sanghar, Shikarpur, Larkana, and Thatta are selected as some suitable sites for the proposed HEPSIS. Additionally, wheat and rice are selected as potential food crops whereas cotton and sugarcane are selected as potential cash crops.
