“We want to make people realise that they can use their gardens, yards and roof terraces to grow food,” says Adolfo López Villanueva, the programme’s director. “With the climate we have in Mexico City you can get between two and three harvests a year and that would help families keep costs down.”

The programme was launched last year. But the spiralling cost of food has given new impetus to plans for its expansion and this year officials have decided to increase its scope by at least 50 per cent.

Together with agronomists from a local university, the city’s government gives families technical support and agricultural supplies to get their vegetable gardens going. Among the crops available are carrots, potatoes, onions, tomatoes and chillies.

“We get them to provide the land and the labour and we provide everything else,” said Mr López Villanueva.
