In the heart of India’s hyper-arid regions, where rainfall is as unpredictable as the monsoon’s mood swings, farmers face an uphill battle to coax life from the parched earth. But a groundbreaking study led by Dr. Birbal from the ICAR-Central Arid Zone Research Institute, Regional Research Station, Bikaner, Rajasthan, is turning the tide. The research, published in ‘The Indian Journal of Agricultural Sciences’ (translated to English as ‘The Indian Journal of Agricultural Sciences’), unveils an Integrated Farming System (IFS) model that’s not just weathering the storm but thriving in it.
The study, spanning from July 2019 to June 2023, compared the IFS model with conventional cropping systems of moth bean and cluster bean. The results are nothing short of revolutionary. The IFS model, which integrates arable crops, horticulture, fodder, dairy, vermicomposting, and mushroom cultivation, supported by rainwater harvesting, showed a mean Cluster Bean Equivalent Yield (CEY) of 7608 kg/ha. This is a staggering 27 times more than the conventional sole cluster bean cropping system, which yielded a mere 274 kg/ha.
Dr. Birbal, the lead author of the study, emphasizes the economic viability of the IFS model. “The IFS achieved annual net returns of ₹1,79,899 with a benefit-cost ratio of 2.40,” he says. “This represents 5.6 and 6.2 times higher net returns than sole cluster bean and moth bean, respectively.” The income share breakdown is equally compelling, with dairy contributing 45.8% of net returns, while horticulture and fodder accounted for 17.8% and 16.5%, respectively.
But the benefits of the IFS model aren’t just financial. The system demonstrated high water use efficiency (2.498 kg/m³) and a reduced water footprint (400 L/kg). With a Sustainable Value Index (SVI) of 0.560, the IFS model proves to be a resilient, sustainable, and economically viable approach for hyper-arid regions.
The implications of this research are far-reaching. For one, it challenges the conventional wisdom that arid regions are only suitable for extensive, low-yield farming. The IFS model shows that with the right integration of crops, livestock, and water management, even the most barren lands can be transformed into productive, profitable ecosystems.
Moreover, the model’s success in enhancing productivity, profitability, and sustainability in hyper-arid regions could pave the way for similar integrated farming systems in other arid and semi-arid regions of the world. This could have significant implications for global food security and the energy sector, as increased agricultural productivity can reduce the need for energy-intensive food imports and support local economies.
Dr. Birbal’s work is a testament to the power of integrated, sustainable farming practices. As he puts it, “The future of agriculture in arid regions lies in diversification and integration, not specialization and isolation.” His research is a beacon of hope for farmers in hyper-arid regions, offering a pathway to enhanced productivity, profitability, and sustainability.
