| Abstract | With a regular increase in food demand, the world faces challenges of intensifying food production per unit area, thus increasing the use of various inputs and the latest technology, resulting a shift in energy usage and increased GHG emissions per unit area. The goal of this research was to investigate various potato production systems in the Sahiwal Division, Pakistan regarding the nexus of Water-Energy- Food and look at certain management practices from the viewpoint of adaptations to climate change. There are three types of farms in the study area, furrow irrigated farms, Drip irrigated farms, and drip irrigated farm where potato are grown for industrial use. Data from a research center in the area is also collected and analyzed, potato is grown there by drip irrigation. For every group three field are selected and five-year data are collected. Water footprint, carbon footprint and energy footprint for all farm types are calculated separately, some other indicator of water and energy use efficiency are also estimated, analyzed and compared. Hot spots for GHG emission are identified. Crop growth model DSSAT is used to evaluate different management practices. The model is calibrated for variety Lady rosette with three-year data (2014-2016) and validated for two-year data (2017-18). Different management practice with respect to climate change mitigation are simulated for drip and furrow irrigation. After simulating Water footprint, carbon footprint and energy footprint are calculated again and compared The drip irrigated farms showed better results in term of production and resource conservation. Irrigation and fertilizer proved major hotspots for GHG emissions. Appropriate use of irrigation water, shifting planting date from October to November and Reducing use of fertilizer; found to be ecofriendly crop management practices. |
