The study on land size class wise growth of crop diversification index from Murshidabad district of West Bengal, India [1], presents a thorough analysis of the spatiotemporal changes in crop diversification across different land size categories from 1995-96 to 2015-16. Crop diversification, as the study rightly points out, holds immense significance in addressing various socioeconomic and environmental challenges, particularly in agrarian economies like India. One of the notable aspects of the study is its utilization of the Gibbs-Martin’s technique [2] to calculate the diversification index. Furthermore, the study sheds light on the differential impacts of diversification across various land size categories, emphasizing that marginal and small land holdings have experienced the most significant improvements. Despite the marginal increase in the diversification index for large landholdings, the study underscores the relatively low contribution of large farmers to the overall diversification process due to their limited presence in the district's farming landscape. The study's conclusion aptly highlights the need for targeted capacity-building programs aimed at sustaining and fostering the diversification process among farmers [3][4][5][6]. This recommendation aligns with the broader objective of ensuring inclusive and sustainable agricultural development, particularly in regions like Murshidabad, where small and marginal farmers constitute a substantial proportion of the farming community. Future research could explore synergies between crop diversification and watershed development interventions to optimize agricultural productivity, water resource management, and rural livelihoods, thus contributing to broader goals of sustainable development and environmental conservation. Integrating water budget calculators (WBCs), groundwater calculators (G-Cals), and AI-ML approaches can significantly enhance the monitoring and promotion of crop diversification. By leveraging these advanced tools and techniques, stakeholders can gain valuable insights into the relationship between water availability, agricultural practices, and crop diversification patterns, thus facilitating evidence-based decision-making and targeted interventions to promote sustainable agriculture. WBCs can be instrumental in assessing the water balance and availability in agricultural areas [7], thereby guiding farmers in making informed decisions regarding crop selection and irrigation practices. By analyzing precipitation, evapotranspiration, infiltration, and runoff, WBCs can help identify regions with water surplus or deficit, enabling stakeholders to optimize water allocation and management strategies [8][9][10][11]. In the context of Murshidabad district, WBCs can provide valuable information on seasonal variations in water availability, helping farmers to diversify crops based on their water requirements and adapt to changing climatic conditions. G-Cals offer insights into groundwater dynamics, recharge rates, and aquifer properties, which are crucial for sustainable groundwater management and agricultural planning [12]. By estimating groundwater levels, flow rates, and storage capacities, G-Cals can help identify areas with high groundwater potential, where water-intensive crops can be cultivated without depleting aquifer resources. Additionally, G-Cals can assess the impacts of irrigation practices on groundwater recharge and quality, informing strategies to minimize water extraction and enhance groundwater sustainability [13][14][15][16]. In Murshidabad district, G-Cals can assist in identifying suitable areas for crop diversification based on groundwater availability and quality, thereby promoting water-efficient agricultural practices. AI-ML approaches offer powerful tools for analyzing large-scale datasets, identifying patterns, and predicting future trends in crop diversification. By leveraging machine learning algorithms, stakeholders can analyze historical crop data, climate variables, soil characteristics, and water availability to develop predictive models of crop diversification patterns. These models can help forecast changes in crop distribution, identify potential barriers to diversification, and recommend targeted interventions to promote diversification among farmers [17][18][19][20][21][22][23][24]. In the context of Murshidabad district, AI-ML approaches can analyze historical agricultural data and climate projections to assess the feasibility of introducing new crops, optimizing crop rotations, and improving water use efficiency, thus enhancing agricultural sustainability and resilience to climate change. In conclusion, by integrating WBCs, G-Cals, and AI-ML approaches, stakeholders can enhance their capacity to monitor, evaluate, and promote crop diversification initiatives in Murshidabad district and similar agricultural regions. These advanced tools offer valuable insights into the complex interactions between water resources, agricultural practices, and environmental factors, thereby facilitating evidence-based decision-making and promoting sustainable agriculture for food security and livelihood improvement.References^Sakil Ansari, Hasibur Rahaman.
