Building Climate-Resilient Food Systems for a Water-Stressed Future

By Vivek Raj, Founder & CEO, Panama Hydro-X

In mid-April, the IMD (India Meteorological Department) forecast El Niño conditions that can strengthen across the Pacific this year. Significantly, El Niño is associated with drier conditions that cause a delayed or deficient monsoon. Historically, this means depressed Kharif sowing, affecting the yields of rice, maize, soyabean and pulses. In turn, the threat of reduced water availability increases both farm stress and inflationary pressure on food prices.

If the April forecast comes true, the country will witness below-normal rains in 2026. IMD projections indicate the southwest monsoon is likely to be at 92% of the LPA (long-period average), the first below-normal monsoon after 2023.

The Rationale for Weather-Resistant Farming

More than 50% of domestic agriculture’s net sown area is rainfed, while accounting for almost 40% of the overall food production. As agriculture remains most vulnerable to climate change conditions like erratic rainfall and extreme weather events, Climate-Resilient Agriculture (CRA) offers an opportunity to manage these varied conditions by boosting crop resistance and resilience.

Accordingly, national programmes such as NMSA (National Mission on Sustainable Agriculture), NICRA (National Innovations in Climate-Resilient Agriculture) and GKMS (Gramin Krishi Mausam Seva) are identifying and expanding climate-resilient systems and practices. The Centre is already promoting CRA practices and implementing policy measures to boost production efficiency, crop diversification and flexible farming practices.

Nonetheless, as climate threats intensify, incremental measures may fall short of what is required. Instead, the need of the hour is to begin building complementary schemes that limit the reliance on rainfall by maximizing water usage and exerting more control over production processes.

In the next quarter century, the UN estimates the global population will reach 9.7 billion, triggering a dramatic rise in demand for food. To meet the unprecedented demand, the food ecosystem must boost production by at least 50%. Simultaneously, it must manage inefficient distribution so that food is delivered to regions with the greatest need. Although agricultural land is limited, expanding production through environmentally unsound or harmful practices is not a viable option.

Environmentally and Economically Sound Practices

In such scenarios, the need of the hour is to adopt farming practices that are both environmentally and economically sound. Therefore, how crops are grown assumes greater importance than what is grown. Herein, controlled environment agriculture (CEA) is useful in cultivating crops and maximizing yields on land not generally used for traditional agriculture.

CEA achieves this goal using facilities such as vertical farms or greenhouses, backed by various supportive technologies that can produce crops even in non-conventional environments, through advancements in data-led monitoring and artificial intelligence. This promotes long-term food security while facilitating environmental sustainability. CEA practices can curb water usage by anywhere between 53% and 98%, even as it restricts chemical usage by as much as 100%. This means less land is needed to produce the same quantity of crops as regular farming.

Given its advantage, India needs a hybrid agricultural model where traditional farming is supported by CEA clusters near urban centres. Besides reducing transportation loss, it will facilitate year-round supplies of high-value crops. While CEA offers efficiency, its high initial investment and energy dependency must be offset via renewable energy integration, especially solar-powered farm systems in water-stressed regions.

The Advantages of Hydroponic Farming

UNDP considers CEA as a bouquet of technologies, including greenhouses, vertical farms and hydroponics, which delink farm production from the monsoons while insulating it from extreme weather conditions and limiting the use of land and water. AI and data-enabled systems permit precise control over temperature, humidity, light and nutrient delivery, thereby delinking production from ambient climate disruptions. This controls water usage and delivers more consistent, predictable agricultural output.

To elaborate, AI-driven hydroponic techniques like automated nutrient dosing, sensor-enabled monitoring and image-based disease detection provide tangible benefits in enhancing yields, optimizing resources and ensuring predictable production outcomes.

As a promising traditional farming alternative, hydroponics concerns the cultivation of plants in nutrient-rich water instead of soil. This saves a substantial amount of water and safeguards crops from soil-borne diseases, allowing year-long production irrespective of weather conditions. Hydroponics also makes urban agriculture a reality by taking food production closer to the cities.

But hydroponics calls for controlled conditions backed by complex management practices to maintain the precise temperature, humidity, lighting, nutrients and pH levels. Such a high degree of consistency is not possible through manual agricultural practices. However, AI manages automated systems seamlessly by continuously monitoring the sensors, adjusting environmental controls and anticipating problems before they break out. This helps in optimizing the use of resources to achieve yields and efficiencies that are not possible through manual management practices.

Considering the advantages of CEA, the practice is finding growing traction globally. According to a Future Market Insights report, the CEA sector was valued at $67.40 billion in 2025. In 2026, it is slated to reach $76.84 billion. By 2036, the report forecasts the market expanding to $284.85 billion, recording a CAGR of 14.00%.

By moving beyond large corporations, hydroponics can potentially transform farming across India. Keeping this in mind, policymakers must introduce targeted subsidies, low-interest financing and public-private partnerships to make hydroponics and vertical farming easily accessible to progressive small and medium farmers.

CEA Will Complement, Not Replace, Traditional Farming

Nevertheless, the above methods are not meant to replace traditional farming, particularly for mass-grown staple crops. But they can play a pivotal role in select segments, especially for high-value crops, medicinal plants, and specialized produce, where quality, consistency, and traceability are crucial.

As climate change events, including El Niño, occur with increasing frequency, it is imperative to review current farming practices. The agriculture of tomorrow will not be measured solely by the amount of produce. Instead, it will be defined by how efficiently, reliably and consistently it can be produced. Agricultural systems that ensure water efficiency, production predictability and climate resistance will be critical in promoting long-term food security and economic viability.

Today, the million-dollar question is not whether Indian agriculture needs to adapt in the era of climate change. Rather, it is about how speedily agricultural systems can be built and programmed to manage the impending ground realities seamlessly.
