The Bellagio Initiative, a £1.2m project to map global philanthropy and produce recommendations on how it can tackle poverty, is calling on people to submit evidence for a new online resource.
It wants contributions including papers, comments and case studies for the online resource, which will host ideas of how philanthropy can reduce poverty.
Nick Perkins, head of research communications at IDS, said it wanted people to tell it what they thought were the key issues in philanthropy and international development.
"We want to know where they think new opportunities for collaboration between philanthropists and those working in international development lie, and share the innovations they believe philanthropists and international development organisations should take forward," he said.
Separately, the Ambassadors for Philanthropy, a project launched by Dame Stephanie Shirley in 2009 that gives philanthropists a platform to talk about their charitable work, has launched a new global site and digital membership scheme.
Roberta d’Eustachio, co-founder and chief executive of the Ambassadors for Philanthropy global enterprise, told Third Sector that it had been getting requests from around the world from people wanting to join it in its work.
"So we are launching a full-scale global membership for philanthropists and people from organisations including non-profits, social enterprises and corporations," she said. "It will give these people more of a voice and promote philanthropy across the world."
She added that a global summit to discuss philanthropy worldwide would be held in London in March 2013.
