Ramesh Kumar, a 42‑year‑old wheat farmer in Gurdaspur, Punjab, India, is already recalculating his budget as fertiliser prices climb and deliveries become erratic.He worries that higher input costs could force him to postpone his daughter’s wedding, delay school fees for his children, or even cut back on the amount of fertiliser he applies – a decision that could lower his harvest.While the conflict between the United States, Israel and Iran unfolds thousands of kilometres away, its ripple effects are felt in the fields of Punjab, Kashmir, Pakistan’s South Punjab, Bangladesh’s Rangpur and Nepal’s Gulmi district.The Strait of Hormuz, a narrow chokepoint linking Gulf oil and gas producers to global markets, handles roughly one‑fifth of the world’s oil and LNG shipments. Disruptions here delay the flow of natural gas used to produce nitrogen‑based fertilisers, inflating freight, insurance and ultimately fertiliser prices.South Asia, home to nearly two billion people, depends heavily on fertiliser‑intensive agriculture. In India, the sector is worth about $400 billion and employs over 46 % of the workforce; in Pakistan, it contributes close to 20 % of GDP; Bangladesh’s agriculture accounts for 12‑13 % of GDP; and Nepal relies on agriculture for roughly 24 % of its economy.Between 30 % and 35 % of India’s fertiliser imports, and up to 25‑30 % of Pakistan’s, Bangladesh’s, and Nepal’s imports, travel through routes that pass the Strait of Hormuz. Any prolonged blockage could therefore strain supply chains across the region.Governments are attempting to reassure farmers. Indian Prime Minister Narendra Modi announced expanded domestic production of urea, DAP and NPK, as well as the rollout of “Made‑in‑India Nano Urea” and solar‑powered irrigation under the PM Kusum scheme.Pakistan’s federal secretary for agriculture highlighted proactive monitoring, increased domestic urea and DAP output, and measures to keep fertiliser affordable.Bangladesh plans to import 500,000 tonnes of urea in the short term and is exploring alternative sources from China and Morocco, while Nepal’s agriculture ministry says supplies for the upcoming rainy season are secured, though it warns of possible shipment delays.On the ground, farmers are already adjusting. In Kashmir, mustard grower Ghulam Rasool says he reduces fertiliser use as soon as price signals rise, even before actual shortages appear. In Pakistan’s South Punjab, wheat farmer Muneer Ahmad fears higher costs will affect the entire community. In Bangladesh, Mohammad Ibrahim notes that fertiliser availability is becoming unpredictable, and in Nepal, Meghnath Aryal worries that delayed deliveries will hurt crop yields.These individual decisions have broader implications. Reduced fertiliser application can lower yields, which in turn pushes up food prices—a critical concern in a region where households allocate a large share of income to food.While no immediate shortage has been declared, the combination of higher global energy prices, logistical bottlenecks and geopolitical risk makes the situation volatile. Authorities in all four countries are urging farmers to supplement chemical inputs with organic alternatives such as manure, compost and green manuring.For Ramesh Kumar and millions of his peers, the distant Gulf crisis is not an abstract geopolitical story; it is a daily calculation of whether they can afford to feed their families and meet essential expenses.

Scientists are preparing to establish 4,500 native trees on the fringes of the Brecon Beacons National Park using a novel fertiliser derived from human urine.The fertiliser was produced by Bristol‑based startup NPK Recovery, which linked its mobile processing unit to the toilets serving roughly 700 revellers at the Boomtown festival in Hampshire last July.During the 2025 event the system generated 540 litres of nutrient‑rich liquid, now earmarked for planting beech, Scots pine and other native species in Wales.The three‑year restoration scheme, funded by a Forestry Commission grant, will also incorporate urine collected from additional events, expanding the supply chain for the circular fertiliser.To launch the initiative, a Scots pine seedling was planted on Thursday morning, symbolising the start of what could become a lasting Welsh forest.Lucy Bell‑Reeves, co‑founder of NPK Recovery, noted that field trials have shown the urine‑based product to be as effective as conventional fertilisers, marking its first application on trees.“Using a waste product to grow trees is a circular solution that can revitalise our struggling native species,” Bell‑Reeves said, adding that “we need to stop flushing crop and tree‑growing nutrients down the loo and start using them to increase our fertiliser security.”The company previously processed 1,000 litres of urine collected from women’s urinals at the London Marathon, converting it into an odour‑free liquid using specialised bacteria that recover nitrogen and other nutrients.NPK Recovery’s mobile laboratory enables on‑site conversion, eliminating the need for transport and preserving nutrient integrity.Partnering with the charity Stump Up For Trees, co‑founded by author‑cyclist Rob Penn, the project builds on the charity’s five‑year effort that has already planted over 500,000 trees in the region, half of its one‑million‑tree target.Penn expressed enthusiasm, stating, “This groundbreaking project has implications for the future of sustainable forestry, and collaboration with NPK Recovery brings much‑needed innovation to the sector.”
