Impact of Interventions of Kolhapur Type Weirs on Irrigation Intensity in Kolhapur District

This study examines the impact of Kolhapur Type Weirs (KTWs), a traditional and effective irrigation intervention, on irrigation intensity in the Kolhapur district of Maharashtra. Kolhapur district is heavily dependent on agriculture, and effective water management plays a pivotal role in ensuring crop productivity and sustainability. Kolhapur Type Weirs are low-cost, farmer-friendly structures designed to increase water availability for irrigation, which in turn, may significantly influence the irrigation intensity in the region. The research utilizes the Z-test to evaluate changes in irrigation intensity, which is defined as the proportion of the gross irrigated area to the total cultivated area. The Z-test is employed to test the null hypothesis that there is no significant difference in irrigation intensity before and after the construction of KTWs. Data on irrigation intensity pre- and post-intervention is collected from agricultural records over several years. Preliminary results suggest a significant increase in irrigation intensity post the introduction of KTWs, reflecting improved water accessibility and efficient irrigation practices. The Z-test results indicate that the increase in irrigation intensity is statistically significant, with a p-value below the 0.05 threshold, leading to the rejection of the null hypothesis. The findings underscore the positive impact of Kolhapur Type Weirs on water resource management in Kolhapur district, contributing to better irrigation outcomes and enhanced agricultural productivity. This study recommends further expansion of KTWs in other water-scarce regions to replicate the observed benefits.
