Unlocking Agricultural Potential: The Role of Irrigation Practices and Cropping Intensity in Vojvodina, Serbia

Agriculture is essential for ensuring food security and driving economic development, particularly in rural areas. Due to the high pressure of climate change, it is crucial to increase food production while carefully managing natural resources. Cropping intensity involves maximizing agricultural land productivity by increasing the frequency and intensity of crop cultivation. Effective irrigation is vital for achieving high cropping intensity and supporting intensive agricultural production. Understanding the interactions between irrigation practices and cropping intensity is critical for developing effective climate change adaptation and mitigation measures in agriculture. Understanding these interactions is important for developing effective climate change adaptation and mitigation measures in agriculture. This study emphasizes the critical need for targeted strategies to optimize irrigation and promote intensive cropping practices in Vojvodina. This research presents an analysis of irrigation practices and cropping intensity in the Vojvodina region. Vojvodina is notable as a main agricultural region in Serbia with a significant contribution to the country's agricultural output. Using remote sensing data and statistical analysis, we investigate the extent and distribution of irrigated agriculture, as well as the intensity of various crops cultivated in this region. Based on a classification of irrigated fields over three years, a final map of irrigated parcels was generated for Vojvodina region. In order to see what kind of crop is usually under irrigation in this region, machine learning-based maps of cropping intensity were generated for 2022 and 2023. These maps contain three main classes: single winter crops, single summer crops, and double cropping. Both irrigation maps and cropping intensity maps were generated using Sentinel-2 images and ground truth data collected for each year. Statistical analysis indicates that only 6.26% of the agricultural areas in Vojvodina are equipped with irrigation systems. Our revealed that irrigation systems are predominantly utilized for single summer crops, accounting for 85.97% and 71.36% of usage in each respective year. In contrast, irrigation of single winter crops increased from 8.77% in 2022 to 20.94% in 2023. Notably, doublecropping, which represents the highest level of cropping intensity, involved only minimal use of irrigation systems: 4.17% in 2022 and 5.60% in 2023. Given that irrigation is crucial for double-cropping practices in Vojvodina, these statistics highlight a significant underutilization of available resources. Our research analysis suggests that approximately 95% of parcels equipped with irrigation systems are not fully utilized. This underutilization points to a significant opportunity for enhancing agricultural productivity. The current irrigation practices are often suboptimal, leading to inefficient water use and limiting the potential for multiple cropping cycles within a year. By addressing the current inefficiencies and leveraging the region's agricultural potential, we can significantly enhance productivity and contribute to sustainable agricultural development. Policymakers, researchers, and farmers must collaborate to implement these strategies, ensuring that Vojvodina remains a cornerstone of Serbia's agricultural output and a model for other regions facing similar challenges.
