Award foundation president Carmencita Abella said the trio had helped harness the technologies to empower their countrymen and worked to create waves of progressive change across Asia.
“Working on critical issues… they are showing how commitment, competence, and collaborative leadership can truly transform individual lives and galvanize community action,” Abella said.
The award, often described as Asia’s Nobel Prize, is named after a famous Philippine president who died in a 1957 plane crash.
It aims to honor people who address issues of human development in Asia with courage and creativity.
One of the 2011 winners was US-trained Indian engineer Harish Hande, 44, for bringing solar lights to a country where half of all households have no electricity, the awards foundation said.
His Solar Electric Light Co.-India has tapped the sun’s energy to light up 120,000 households and is now one of the country’s largest solar technology providers.
Indonesian social worker Tri Mumpuni, 46, was recognized after her IBEKA foundation built 60 small power plants harnessing the energy of water stored in dams to bring electricity to half a million people, the awards foundation said.
She was once kidnapped with her husband by former separatist rebels in Aceh province while pursuing her non-governmental group’s project to bring electricity to rural Indonesia.
In the Philippines, Dutch marine engineer Auke Idzenga’s Alternative Indigenous Development Foundation won for using an ancient, near-forgotten technology, the ram pump, to help impoverished communities on Negros island.
Re-engineered for upland farms, the pump gave the communities clean, cheap water for household use and for raising livestock, fish, and small farms, it said.
A ram pump, which does not need an external power source, harnesses the force of a large body of moving water to pump a small amount of water uphill.

The winners are to receive their awards in Manila on August 31.
