Abstract:

Climate change significantly affecting the agriculture sector globally, the world population is projected to be 9.1 billion by the year 2050, and about 70% extra food will be required. One of the main challenges regarding food security is the negative effects of climate change on crops. The farming of chili is vulnerable to the adverse impacts of climate change, leading to a significant decline in production due to heightened rain and drought occurrences. Current research carried out to investigates the impacts of climate change on chili production and income, involving the entire cultivation process from planting to harvest in Sindh province of Pakistan. The findings of this study reveal that climate change (Drought or heavy monsoon rain) employs a visible impact on both production efficiency and the income derived from chili cultivation. Thus, overall net-revenue from per acre is Rs. 269760.25 in the rainy season and Rs. 209,281in the dry season. The calculated return cost ratio (R/C) is computed at 2.46 and 1.97 in rainy and drought season respectively, declares the continued feasibility of chili farming, despite the challenges posed by climate change, Cobb-Douglass, function, analysis reveals the influence of various factors on chili production during both the dry and rainy seasons. In the dry season, the production of chili is significantly (R2= 0.82) affected by variables such as land area, seeds, manure, pesticides, and labor. Similarly, in the rainy season, all the parameters show positive signs, indicating that land area, seeds, manure, pesticides, and labor have a significant impact on chili production. Although variable of chemical fertilizer does non-significant effect on chili production in both seasons.
