David McTaggart's home for the last 12 years of his life was the medieval village of Paciano in the hills of the central Italian region of Umbria. Here he gave new life to an old olive farm, and under his PaxJani label produced "the green gold" that this region is so famous for. This was not as much a business plan as a means to campaign for organic farming in the region which successfully inspired many local farmers to convert to organic production.

Nestled in the hills surrounding Lake Trasimeno, where Hannibal famously fought his battle of Trasimeno against the Roman legions in 217 BC, Paciano is a village rich in history that traces back to Etruscan times. It is surrounded by olives groves, woodlands and vineyards, in an area of great natural beauty which is also rich in biodiversity and wildlife.

The village has long supported efforts to achieve environmental sustainability, social inclusion and the fostering of a culture of peace. It is one of only a few municipalities in Umbria to be accepted into the "Virtuous Comuni" network, and since 2015 is a member of the international association "Mayors for Peace" based in Hiroshima.
