2.2. Data and Variables:
Data on the variables chosen for this study, wheat production (Wheat), carbon dioxide concentrations (CO2), average temperature (temperature), average precipitation (Precip), agricultural land used for wheat cultivation (Area), and water accessibility (Water) were gathered during 1972 - 2022. The Economic Survey of Pakistan is a valuable resource that provides crucial information about the country’s wheat harvest. This survey, which has been conducted multiple times, is extensively analyzed to gather data on the quantity of wheat produced, measured in tons. One significant factor that positively influences wheat output is the improved water utilization by plants, which is facilitated by the presence of carbon dioxide. To obtain emission projections, all relevant information is sourced from the Carbon Dioxide Information Analysis Center website, with measurements expressed in SMT (thousand metric tons). In regions near or within the tropics, wheat production is known to face challenges due to high temperatures. The temperature (C) and average rainfall (mm) data was collected Metrological Department of Pakistan to assess the impact of the same on wheat yield during 1972 - 2022. Apart from focusing on wheat production, the Economic Survey of Pakistan also addresses various other agricultural aspects such as finance, wheat procurement price, fertilizer off-take, and technology. This comprehensive survey provides comparable figures and serves as a valuable tool for understanding and analyzing the agricultural sector in Pakistan.
