Crops of Conflict

As water and climate become instruments of geopolitical leverage, India has an opportunity to turn agricultural resilience into a new form of South-South diplomacy. Climate change is making an old truth harder to ignore: food security is national security. As water becomes scarcer, harvests more erratic and trade policies more protectionist, agriculture is moving from the margins of geopolitics to its centre. Nowhere is this clearer than in Africa, where fragile food systems intersect with contested rivers, conflict and disrupted supply chains. For India, this presents not merely a humanitarian challenge but an opportunity to practise a more strategic form of food diplomacy. Clear Warning The Nile basin offers the clearest warning. Egypt, Sudan and Ethiopia depend heavily on the river, directly or indirectly, for agriculture and livelihoods. Egypt obtains roughly 90-95 percent of its water from the Nile, with most of its withdrawals going to agriculture. Wheat, rice, maize and cotton are therefore inseparable from the country's water security. Sudan is similarly dependent on the Main Nile and its Blue and White Nile tributaries for crops including sorghum, wheat, cotton and sugarcane. Ethiopia, by contrast, relies much more heavily on rain-fed agriculture, but the Blue Nile remains crucial to its plans for agricultural and economic expansion. The Grand Ethiopian Renaissance Dam (GERD) has transformed this already delicate equation. The Blue Nile supplies roughly 85 percent of the Nile's runoff, giving Ethiopia substantial geographical leverage upstream. Egypt and Sudan, downstream and more dependent on the river, have consequently viewed the dam through the prism of food and water security. The dispute has its roots partly in the 1959 agreement that allocated Nile waters between Egypt and Sudan, but the rise of Ethiopia as a major upstream power has altered the political balance. The stakes are enormous. A disruption to water availability is not simply an environmental problem when millions depend on irrigated agriculture. It can affect food prices, livelihoods, migration and political stability. Across the basin, the consequences potentially extend to hundreds of millions of people. The lesson is straightforward: rivers can become geopolitical infrastructure, and crops can become strategic assets. Critical Role This is where India can play a useful role. Its longstanding diplomatic, commercial and maritime links with Africa give it an established platform. Its experience in producing wheat, rice and millets, meanwhile, gives it something more tangible: the ability to contribute to food-supply resilience. Egypt, for instance, remains heavily dependent on imports and is projected to require around 13 million tonnes of wheat imports to bridge its consumption gap. Sudan’s agricultural crisis is still more acute. Conflict and climate stress have sharply reduced cereal production, leaving output well below recent historical averages. India could therefore build food diplomacy around two complementary tracks. The first is supply. Predictable grain arrangements and strategic food buffers could help vulnerable countries absorb shocks in international markets. The second is technology. India's experience with micro-irrigation, precision farming and water-use efficiency offers tools that may help African farmers produce more with less water. The Per Drop More Crop component of the Pradhan Mantri Krishi Sinchayee Yojana is one example. Drip irrigation, improved canal management, seepage reduction and precision agriculture cannot resolve a dispute over the Nile, but they can reduce the amount of water required to produce a given crop. For this to become a durable strategy, however, India will need to move beyond individual projects. Bilateral agricultural agreements with African countries could be converted into longer-term trade corridors and grain-supply arrangements. Multilateral platforms, including BRICS, could provide mechanisms for greater transparency in food distribution and market stabilisation. Seed exchanges could focus on drought-tolerant millets, biofortified wheat and heat-resistant maize suited to increasingly volatile climates. Indian private enterprise could be brought into this architecture. Agritech startups and Farmer-Producer Organisations could be encouraged to enter African markets through export-linked grants, incubation programmes and risk-sharing mechanisms. EXIM Bank credit lines and export guarantees could reduce the financial risks of deploying solar cold chains, irrigation systems and agricultural technologies in politically volatile markets. Public-private partnerships could also help Indian firms adapt AI-based crop advisory systems and IoT-enabled water sensors to African soils and farming practices. The larger opportunity is strategic. India’s relationship with Africa need not be confined to trade, infrastructure or diplomatic declarations. Agriculture offers a practical form of South-South cooperation in which food, technology and water efficiency reinforce one another.

The Institution That Shaped Modern Indian Science

A journey from Mahendra Lal Sircar's vision to global scientific excellence.

The year 2026 marks the sesquicentennial of the Indian Association for the Cultivation of Science (IACS), Kolkata, the oldest institution in India devoted exclusively to fundamental scientific research. Founded on 29 July 1876 by the visionary physician and educationist Dr Mahendra Lal Sircar, IACS emerged when India lacked institutions dedicated to experimental science. Convinced that scientific inquiry was indispensable for national progress, Sircar established an institution to nurture original research by Indians while promoting scientific knowledge among the public. One hundred and fifty years later, IACS remains one of India's foremost research institutions, its history closely intertwined with the evolution of modern science in the country.


The genesis of IACS reflected the intellectual ferment of the Bengal Renaissance. Trained in Western medicine yet deeply committed to India's intellectual emancipation, Sircar argued that science should be cultivated through experimentation and discovery rather than merely imported through textbooks. Inspired by institutions such as the Royal Institution of Great Britain, he envisioned a publicly supported national laboratory where Indians could pursue independent scientific research. At a time when such opportunities were scarce under colonial rule, IACS became the country's first permanent home for fundamental scientific investigation.


During its early decades, the Association combined public lectures and scientific demonstrations with laboratory research, fostering an interdisciplinary culture spanning physics, chemistry and the natural sciences. Though modest in resources, it established an enduring tradition of curiosity-driven research.


The defining chapter in IACS history began with the arrival of Chandrasekhara Venkata Raman in 1907. While serving in the Indian Finance Department, Raman spent his evenings and holidays conducting experiments at IACS on acoustics, optics and the scattering of light. On 28 February 1928, he and his collaborators announced the discovery of the inelastic scattering of light by molecules—the Raman Effect—creating a powerful spectroscopic technique that transformed the study of molecular structure.


Today, Raman spectroscopy is indispensable across chemistry, materials science, biology, medicine, pharmaceuticals, environmental monitoring and planetary exploration. For this achievement, Raman received the 1930 Nobel Prize in Physics, becoming the first Asian to win a Nobel Prize in the sciences for work conducted entirely in India. His success demonstrated that world-class scientific research could emerge from Indian laboratories.


Yet IACS's scientific legacy extends far beyond Raman. Kedareswar Banerjee advanced crystallographic research through pioneering X-ray crystallography, while Satyendra Nath Bose's association with IACS enriched the intellectual environment that fostered advances in quantum physics. Meghnad Saha's theory of thermal ionisation transformed astrophysics, and together Raman, Bose and Saha established Kolkata as one of Asia's leading scientific centres.


The institution also made major contributions to chemistry through Jnan Chandra Ghosh, whose work in physical chemistry laid foundations for modern chemical research in India. Following Independence, IACS expanded into chemical sciences, materials science, biological sciences and theoretical physics, reflecting the increasingly interdisciplinary nature of scientific inquiry.


Among its distinguished scientists was Asima Chatterjee, whose pioneering research on natural products chemistry and medicinal plant alkaloids transformed phytochemistry and contributed significantly to pharmaceutical science. Ajoy Ghatak further strengthened IACS's reputation through his work in fibre optics, waveguides and laser physics, while his textbooks educated generations of physicists and engineers. More recently, IACS researchers have advanced ultrafast spectroscopy, nanomaterials, renewable energy, molecular electronics, quantum materials and computational biology.


Today, IACS functions as a deemed-to-be university under the Department of Science and Technology, Government of India. Its interdisciplinary research spans the chemical, physical and biological sciences, supported by advanced facilities in spectroscopy, microscopy, X-ray diffraction, electron microscopy, computational modelling and materials characterisation. Its doctoral and postdoctoral programmes continue to produce scientists who contribute to universities, research laboratories and industry worldwide.


The institution's enduring strength lies in its commitment to curiosity-driven research. Unlike organisations established primarily for technological development or industrial applications, IACS has consistently recognised that transformative innovation begins with fundamental scientific understanding. This philosophy, articulated by Mahendra Lal Sircar nearly 150 years ago, remains especially relevant in an era defined by quantum technologies, artificial intelligence, sustainable energy and molecular medicine.


The sesquicentennial of IACS celebrates not only a remarkable institution but also the evolution of Indian science. From its modest beginnings in colonial Calcutta to its emergence as an internationally respected research institution, IACS has nurtured Nobel laureates, pioneering physicists, eminent chemists and generations of young researchers who continue to expand the frontiers of knowledge.


As IACS enters its second century and a half, it carries forward Mahendra Lal Sircar's vision that science should be pursued with intellectual freedom, experimental rigour and an unwavering commitment to the advancement of humanity. Its 150-year legacy remains a powerful reminder that the greatest scientific discoveries begin with curiosity and flourish in institutions dedicated to excellence.
