Riaz Hasan obituary

My father, Riaz Hasan, who has died aged 87, was a water resources engineer with a distinguished career working across 40 countries – in the 1970s with the British firm Halcrow and, from the 80s, at the UN and the World Bank.

Originally from Hyderabad, Riaz arrived in the UK in 1965 with £3 and an A–Z, invited, like many engineers in India at that time, by the government. After completing a master’s degree in water resources at Bradford University, where he developed a love of Yorkshire pudding and received his degree from Harold Wilson (which he described as a real privilege), he embarked on his career designing life-saving, long-term water and food solutions for the most vulnerable and those affected by war, famine and natural disasters.
