1. Introduction. Yadgir, a rural district nestled in the heart of Karnataka, India, grapples with the perpetual challenge of water scarcity, a concern exacerbated by erratic rainfall patterns and depleting water resources. One of the region's time-honoured solutions, tank desilting, has emerged as a promising intervention to rejuvenate water bodies and mitigate the impact of droughts. This article delves into the significance of tank desilting in rural Yadgir and its implications for sustainable water management. Tank silt is a fine soil particle transported from the catchment area through surface runoff and soil erosion along with crop debris and deposited as sediment in the water spread area of the tanks constructed for rainwater harvest. These sediments when decomposed over the period become nutrient-rich soil amendments loaded with organic matter with good physical properties. Nutrient flow in the undulated plains or watersheds; especially the leaching of soil nutrients along the water stream and accumulation in natural or manmade barriers such as tanks, ponds, ditches, lakes, and rivers is a well-documented phenomenon. Agricultural lands form a major part of the catchment areas and contribute to the tanks' rainwater storage. Intermittent and high-intensity rainfall during the monsoons causes heavy surface runoff and erosion of valuable nutrient-rich topsoil from the surrounding agricultural lands. Siltation adversely affects the storage capacity of tanks in the long run. Hence, for the conservation and rehabilitation of traditional water tanks desilting is necessary which enables collecting and storing enough water for agriculture and the effective utilization of silt as a soil amendment in agricultural lands. 2. Understanding the Context. Yadgir, characterized by its predominantly agrarian economy, heavily relies on rain-fed agriculture for sustenance. However, recurrent droughts and inadequate water infrastructure have perpetuated the cycle of poverty and vulnerability among its populace. The degradation of traditional water storage systems, such as tanks due to silt accumulation, has further compounded the region's water woes, leaving communities parched and agricultural lands barren. Crop and irrigation practices: About 75% of the geographical area of the district is under cultivation. Irrigation through dug wells is more prevalent in Yadgir taluk, whereas irrigation in Shorapur and Shahpur taluks is through the canal of the Upper Krishna Project. Lift Irrigation Schemes are under implementation along the Bhima River. The crops cultivated in the district are mainly rainfed. The major crops of the district are Jowar, Bajra, Gram, Tur, Groundnut, Sunflower, and Sugarcane. The irrigated crops are rice, wheat, and sugarcane. Yadgir's geographical setting plays a critical role in its water security challenges. The district is characterized by undulating terrain, shallow soil cover, and limited surface water resources. Moreover, Yadgir is predominantly dependent on rain-fed agriculture, making it particularly vulnerable to fluctuations in rainfall patterns. Seasonal Groundwater Fluctuation: After seasonal rainfall, the groundwater level records a rise, indicating recharge to groundwater. During the pre-monsoon period, there was a depletion of groundwater level due to exploitation, natural discharge, and no recharge. This is manifested as a fall in groundwater level during the pre-monsoon period. Historically, Yadgir has relied on traditional water management systems such as tanks, reservoirs, and check dams to harness rainwater and sustain agriculture. However, these systems have suffered from neglect, siltation, and insufficient maintenance over time, compromising their effectiveness in water storage and recharge. Climate change has intensified the challenges of water security in Yadgir. Erratic rainfall patterns, prolonged droughts, and extreme weather events have become more frequent, disrupting agricultural cycles and exacerbating water scarcity. The district's vulnerability to climate change underscores the urgent need for adaptive measures to enhance resilience. Excessive extraction of groundwater for irrigation and drinking water purposes has led to the depletion of aquifers in Yadgir. Unregulated extraction practices, coupled with inadequate recharge mechanisms, have contributed to the declining groundwater levels, posing long-term sustainability challenges. Institutional and governance factors also influence water security in Yadgir. Limited coordination among government agencies, lack of community participation in water management initiatives, and inadequate infrastructure pose barriers to effective water governance and resource management. Water scarcity has profound socio-economic implications for the residents of Yadgir. Reduced agricultural productivity, livelihood insecurity, migration, and conflicts over water access are some of the consequences faced by communities grappling with water stress. Addressing the water security challenges in Yadgir requires a multi-faceted approach encompassing sustainable water management practices, watershed conservation measures, promotion of water-efficient technologies, community engagement, and policy interventions. By adopting a holistic and participatory approach, stakeholders can work towards ensuring water security for present and future generations in Yadgir. Groundwater-related issues and problems: In the Yadgir district, variable stages of groundwater development are noticed as per the March 2017 estimations. In Yadgir taluk the stage of groundwater extraction is 79 %, wherein it requires a suitable management plan to arrest further deterioration of the groundwater. The quality of groundwater in the district in general is good and potable. However, EC and fluoride, nitrate and arsenic concentrations beyond permissible limits have been found to occur in a few samples collected from all three taluks. Yadgir district is one of the aspirational districts identified in Karnataka State which is affected by poor socio-economic indicators. Scientific development on all fronts including the water sector in the district can lead to the overall improvement in the socio-economic conditions in the district. As the Yadgir taluk is semi-critical, recharging the dry phreatic aquifer through artificial recharge structures, like check dams, percolation tanks etc. is recommended. 3. The Role of Tank Desilting. The application of tank silt, also known as tank silt manure or tank silt compost, involves utilizing the nutrient-rich sediment extracted during tank desilting operations as organic fertilizer or soil amendment in agriculture. Tank silt application is a sustainable practice that not only helps in managing sediment accumulation in water bodies but also enhances soil fertility, improves crop productivity, and promotes ecological balance. The first step in tank silt application is the collection of sediment from the bottom of tanks or reservoirs during desilting operations. Sediment may contain organic matter, nutrients, and beneficial microorganisms that are valuable for soil health and plant growth. In this dire scenario, tank desilting emerges as a beacon of hope, offering a cost-effective and eco-friendly solution to enhance water availability. Desilting involves the removal of accumulated silt and debris from the tank beds, thereby increasing their storage capacity and reinvigorating groundwater recharge. This process not only augments water retention but also mitigates the risk of flooding during monsoons, fostering resilience against climate-induced disasters. Tank desilting plays a crucial role in addressing water scarcity and promoting sustainable water management practices in Yadgir, Karnataka. This intervention involves the removal of accumulated silt and debris from tanks in traditional water storage systems prevalent in the region. Soil Health Benefits: Tank silt application improves soil health by increasing microbial activity, enhancing soil biodiversity, and stimulating nutrient cycling processes. The organic matter in the silt acts as a natural soil conditioner, replenishing soil organic carbon and improving soil tilth. Healthy soils support vigorous plant growth and reduce the need for synthetic fertilizers and chemical inputs. Nutrient Contribution: Tank silt serves as a valuable source of nutrients, including nitrogen, phosphorus, potassium, and micronutrients, which are essential for plant growth. The organic matter present in the silt improves soil structure, water retention, and nutrient availability, thereby enhancing soil fertility and promoting healthy root development. Crop Yield and Quality: Incorporating tank silt into agricultural soils can lead to significant improvements in crop yield and quality. The balanced nutrient composition of the silt promotes vigorous vegetative growth, flowering, and fruit set, resulting in higher yields and better-quality produce. Additionally, crops grown in silt-amended soils may exhibit increased resistance to pests, diseases, and environmental stresses. Water Storage Capacity Enhancement: Over time, tanks in Yadgir accumulate sediment and silt, reducing their storage capacity and impeding water retention. Desilting removes these obstructions, allowing tanks to regain their original storage capacity and better capture rainwater during monsoon seasons.
