These photographs celebrate and honour the lives and work of amazing individuals and organisations that have made an impact on development, empowerment, poverty reduction and the environment across the globe. The collection includes those who have influenced and contributed towards improving lives of marginalised and vulnerable groups and who help stand up for their rights. It also includes those who have worked and are working relentlessly on issues relating to our understanding of the environment including sustainable use of resources, respect for wildlife and awareness raising of our role in taking care of Planet Earth. This Wall currently exists in physical form in IPE Triple Line office in London and is growing. We would like to extend its presence to the virtual world and to share our sentiments and appreciation towards these Influencers with everybody and are interested to hear from you on who you believe has influenced global development.
