Soil moisture retention has declined to nearly half of earlier levels due to organic matter loss, while inefficient irrigation practices contribute to excessive groundwater use. Drip systems demonstrate the potential to reduce water use by nearly 60%, making them vital for drought-prone regions. Drawing on scientific assessment and community practices of the Mannervarlu, Maria, and Madia tribes, this paper suggests diversified cropping, agro forestry, ET - guided irrigation, and improved soil management as pathways toward a resilient agricultural system. The study concludes that integrating simple physics -based tools with local knowledge is essential for sustainable farming in Nanded. Keywords: Agriculture Physics, Environment, Climate Variability, Soil Moisture, Nanded District 1. Introduction Nanded district, located in the Deccan Plateau, is one of Maharashtra’s agriculturally significant regions. Its climate is classified as hot Semi-Arid and is strongly influenced by the monsoon system. Agriculture remains the backbone of the regional economy, with major crops including jowar, soybean, wheat, maize, pulses, cotton, bananas, and mosambi. The Mannervarlu community, found mainly in Nanded, Dharashiv, Latur and Hingoli, has historical links to Telugu -speaking regions along the Maharashtra-Telangana border. Traditionally migrant farmers, they are now settled as agricultural labourers, small cultivators, and tenant farmers, and some also collect forest medicinal plants for income. Their practices blend older cultural traditions with present-day agricultural needs. The Maria and Madia communities are also present in Nanded and continue to follow traditional, biodiversity-friendly farming methods.

Review Literature Nanded’s uneven terrain results in varying soil depths -shallow on slopes and deeper in valleys. Despite a robust agricultural heritage supported by communities such as the Mannervarlu, Maria and Madia, Nanded faces severe agrarian distress. Irrigation challenges, groundwater depletion, monsoon unpredictability, and rising temperatures have contributed to crop failures, economic hardships, and a tragic increase in farmer suicides -from 110 cases in 2023 to 138 in 2024. This region depends strongly on agriculture and is situated on the Deccan Plateau with a hot semi -arid climate. The district’s farming activities are supported by several rivers, mainly the Godavari, along with the Penganga, Manjara and Manar. This study aims to provide: 1. A scientific evaluation of environmental challenges in Nanded 2. Physics-based mathematical tools for better farming decisions 3. Sustainable solutions adapted to local climatic and social realities 4. A socially impactful perspective to support farmers, policymakers, and researchers. 3. Methodology The study employs a comprehensive multidisciplinary framework that blends field observations, environmental assessments, and physics -based modelling to evaluate agricultural conditions in Nanded. Data from district agricultural records (2023 –2025), along with soil profiles, rainfall patterns, and government climate datasets, form the empirical foundation of the analysis. Local farming systems and community -driven cropping methods were also examined to understand region-specific challenges and traditional adaptation strategies. Sainath A.

These scientific tools are supported by analytical methods such as long -term climate trend comparison, environmental impact evaluation, and vulnerability mapping of farming households. This combined methodological structure ensures an original, data -driven, and region - specific assessment of Nanded’s agricultural landscape. The region’s primary soil groups -black, lateritic (rusty red color due to its high oxide content) and red soils -were also examined for their crop suitability and changing behavior under stress. Findings indicate that these soils, once highly productive, are increasingly affected by declining rainfall, rising temperatures, and nutrient depletion, highlighting the urgent need for sustainable management and informed planning. 4. Results and Discussion 4.1 Climate Variability and Changing Rainfall Patterns Nanded’s monsoon has become highly erratic, with rainfall falling by about 20% in 2023 and effective rainy days shrinking from nearly 60 to just 25 -30. Sudden, intense showers reduce soil absorption and worsen water shortages. These climatic stresses have deepened the agrarian crisis, with farmer suicides rising from around 110 in 2023 to 138 in 2024. In 2023, Marathwada faced a 20.7% rainfall deficit, and farmer suicides in Nanded rose from about 110 to 138 by 2024. Falling soil fertility, extreme weather, and growing debt have deepened distress, leaving many families struggling and feeling unsupported.

Soybean and tur production often drops by 18 –25% in deficit rainfall years, while cotton shows large fluctuations about 22 -30%, due to heat stress and pest attacks. Repeated flood events, including those recorded in 2006 and again between 2020 and 2024, have caused extensive crop losses. Overall, climate instability has become one of the most critical challenges affecting agricultural productivity in Nanded. 4.2 Modelling Water Requirements Using Physics Concepts 4.2.1 Evapotranspiration-Based Water Demand Crop water use was estimated using the formula: W = A × ETW For a one -acre plot (4047 m²) with a mean evapotranspiration rate of 4.5 L/m²/day, the theoretical water demand is: W = 4047 × 4.5 = 18,211.5 L/day However, field reports indicate that many farmers apply 28,000–34,000 L/day , which means irrigation volume exceeds actual requirement by almost 40%. This surplus accelerates groundwater decline-one of Nanded’s most critical challenges. 4.2.2 Efficiency of Drip and Flood Irrigation Irrigation efficiency is defined as: η = Wplant Winput ×100 • Flood irrigation efficiency ≈ 35% • Drip irrigation efficiency ≈ 90% The shift from flood to drip improves water-use efficiency by: η = 90 −35 90 ×100 =61% Thus, farmers adopting drip systems can save almost 60% of daily water use, making it crucial for drought-prone regions like Nanded.

Effects of Low Moisture Capacity • More frequent irrigation cycles • Loss of nutrients due to leaching • Rising fertilizer expenditure • Long-term decline in soil productivity Improvement Strategy Increasing soil organic matter by just 1% can enhance water-holding capacity by nearly 20,00025,000 L per acre, reducing dependence on groundwater and improving crop resilience. 4.4 Heat Stress and Crop Development Using Growing Degree Days (GDD) Growing Degree Days help farmers identify suitable sowing periods and track crop maturity. GDD = ∑(Tavg − Tbase) Cotton requires roughly 2100 GDD . • At 28°C, daily heat units = 18 → approx. 117 days to maturity • At 31°C, daily heat units = 21 → approx. 100 days to maturity Although higher temperatures shorten crop duration, they often decrease yield quality by affecting boll formation and increasing pest exposure. 4.5 Social and Cultural Dimensions of Farming Communities The Mannervarlu , Maria and Madia communities contribute distinct traditional practices to Nanded’s agricultural landscape. • Mannervarlu farmers rely on mixed cropping, small -scale cultivation and forest -based income sources.

The combination of traditional ecological knowledge with scientific tools such as ET calculation, GDD modelling and soil testing has the potential to greatly enhance agricultural sustainability in Nanded. 4.6 Environmental Constraints Affecting Nanded Agriculture Field observations and dataset analysis identify the region’s major environmental challenges: 1. Declining rainfall and irregular monsoon cycles 2. Excessive groundwater withdrawal and shrinking water tables 3. Soil nutrient imbalance due to repetitive monocropping 4. Increased temperature variability and heat waves 5. Recurring drought–flood cycles 6. Loss of forest cover and pollinator decline 7. Market instability driven by APMC dependence 8. Financial stress, ultimately contributing to farmer distress and suicides These issues collectively reduce productivity and increase vulnerability. 4.7 Institutional and Technological Factors Affecting Agriculture 4.7.1. Use of Technology Drip irrigation is increasingly adopted in Nanded as it delivers water directly to plant roots, reducing losses from evaporation and runoff. This is crucial in a water -scarce region, helping farmers maintain soil moisture more efficiently. Farmers are also using soil -testing kits to check nutrient and pH levels, which supports better fertilizer decisions and improves crop health while reducing chemical overuse. Institutions like NABARD further promote soil -health programs to guide farmers toward sustainable practices. 4.7.2. Changing Crop Types Marathwada’s drought-prone climate and declining monsoon rainfall have pushed farmers to shift crop choices. In Nanded, traditional low -water crops like jowar and urad have decreased, even as water availability continues to fall, creating additional pressure on already vulnerable rain -fed agriculture.

Institutional Infrastructure Nanded has a moderately developed agricultural setup consisting of 19 APMCs, 237 godowns, 5 cold storages, 2 soil-testing labs, 750 farmers’ clubs, and over 3,000 agro-input outlets. Two Krishi Vigyan Kendras (KVKs) support training and extension. The district is also served by commercial banks, cooperative banks, Maharashtra Gramin Bank branches, and nearly 900 Primary Agricultural Cooperative Societies that support credit flow. 4.7.4. Market Structure (APMCs) The district’s 19 APMCs mainly trade turmeric and bananas, along with wheat, rice, cotton, and soybean. These markets play a key role in price discovery and farmer income stability. Sr. No Name Est. Year Chairman No. of Godowns 1. Bhokar 1960 Jagdish Balajirao Kalyankar 5 2.

Scientifically Scheduled Irrigation • Use ET values and soil moisture sensors to determine irrigation timings. • Provide water only when moisture falls below 25%, preventing wastage and conserving groundwater. 4.8.2. Diversified Cropping Systems • Reduce water-intensive crops like sugarcane in dry belts. • Encourage pulses, oilseeds, and millets that require less water. • Recommended intercropping patterns: o Soybean + Tur o Cotton + Urad 4.8.3. Water Conservation Structures • Construct farm ponds, check dams, and percolation tanks. • Install recharge shafts near borewells to recover groundwater levels. • Promote rooftop rainwater harvesting in villages and farm houses. 4.8.4. Soil Health Improvement • Incorporate compost, green manure, and biochar. • Reduce chemical fertilizers by 20% per year, replacing them with organic additives. 4.8.5. Microclimate Management Planting 20-25 trees per acre creates shade, decreases evaporation, reduces wind speed, and improves biodiversity. 4.8.6. Strengthening Market and Institutional Support • Expand cold-storage networks for fruits and vegetables. • Increase transparency and farmer participation in APMC operations. • Encourage participation in Farmer Producer Organizations (FPOs) to increase bargaining power. 4.9 Graphs The graphical analysis presents several key trends in Nanded’s agricultural system. Livestock numbers show distinct fluctuations, with cattle remaining stable initially, declining mid-period, and
