TUNIS — Mouled, the commemoration of the Prophet's birth, is expected to fall on Tuesday 25 August this year, corresponding to 12 Rabi' al-Awwal 1448, the City of Science in Tunis announced in a statement published this week.

The calculation runs as follows. The lunar conjunction occurs on Wednesday 12 August at 18:37 Tunis time. The following evening, Thursday 13 August, the sun sets over Tunisia at 19:14 and the moon at 19:45 — a gap of 31 minutes, enough for the crescent to be observed by telescope. On that basis, Friday 14 August marks the start of Rabi' al-Awwal 1448, which places the twelfth day on 25 August.

The City of Science restated that it is publishing calculations, not a ruling. The Mufti's office, Diwan al-Ifta, remains the authority that officially announces the beginning of Hijri months and the dates of religious festivals.

Why an astronomical notice is a cultural event

In most years the announcement is treated as a piece of practical information, and it is: it tells families when to take leave, when Kairouan will fill with visitors, and when the shops will be busiest. Kairouan holds the largest Mouled gatherings in the country, and the date determines the movement of tens of thousands of people towards it.

But the notice also marks the start of the commercial season for a single ingredient. Assidat zgougou — the dark pudding made from the ground seeds of the Aleppo pine — is the dish Tunisian households associate with the festival, and it is prepared in almost every home in a two-week window around the date. Few culinary traditions anywhere are as concentrated in time or as dependent on one wild-harvested product.

The forest behind the dish

Zgougou is not farmed. It is gathered from Aleppo pine cones in the forests of the centre-west, above all in the Kasserine region, by seasonal collectors working in difficult conditions for a fraction of the retail price. The chain that follows — collection, drying, shelling, wholesale, roasting — adds most of the value after the forest.

That is why a second item of news this week belongs in the same story. The Directorate General of Forests and the United Nations Food and Agriculture Organization announced financing of $2.48 million to preserve the Aleppo pine forests of Kasserine, a stand under sustained pressure from wildfires, drought and land-use change.

The connection is direct and rarely made out loud: the price of a kilo of zgougou in a Tunis market in August is a function of how the previous summer's fires went in Kasserine. Households experience it as inflation on a festive dish. It is, more precisely, a forest yield problem transmitted through five intermediaries.

What is being proposed

Foresters and rural development specialists have argued for years that the value chain should return more to the collectors, on the grounds that people who earn a living from a forest have an interest in it standing. The tools discussed are familiar from other non-timber forest products: collector cooperatives with drying and shelling equipment, so that the first processing step happens in the region rather than in coastal warehouses; a geographical indication protecting Kasserine zgougou, along the lines of what has been done for Tunisian olive oil and dates; and harvesting calendars that leave enough cones for natural regeneration.

The FAO financing announced this week is aimed at the forest itself rather than at the trade. Whether it is followed by work on the chain above it will determine whether the tradition still has a domestic supply behind it in twenty years, or whether Tunisia ends up importing the main ingredient of its most Tunisian dessert. In the meantime, the date is set — subject, as always, to Diwan al-Ifta.
