Grannies could be the vital ingredient that would make health and development projects in poor countries really take off, according to the United Nation's Food and Agriculture Organization.
While Westerners often treat older people as second-class citizens, in Africa and much of the non-western world elders are listened to as respected members of their families and communities, experts say.
Getting grandmothers to understand and take part in nutrition, health and community development projects can significantly raise success rates, says FAO Nutrition Expert William Clay.
Grannies, who in many countries may be aged 40 or less, are "an abundant resource for development in all countries that is vastly under-utilized," he notes.
The pro-granny approach was pioneered by American community development and health specialist Dr. Judi Aubel who presented her "grandmother-inclusive methodology" at a seminar held at FAO recently.
"Elders are natural leaders. Young people are taught to value their knowledge and experience and are expected to look to them for advice," Aubel explained.
Aubel directs a fledgling NGO called The Grandmother Project. Using the grandmother-inclusive approach it says it has greatly increased the success of maternal and child health projects in Senegal, Mali and Laos.
The Grandmother Project's method often uses songs written by local trainees to encourage other senior women to become involved.
One song goes like this:
'Dearest grandmother, you are so wonderful,
You have a big heart and are full of understanding.
May God give you long life.
"When one group heard that song it brought tears to their eyes. They couldn t wait to come on board," Aubel said.
