The Eye on Earth Summit 2015 will seek to better understand the supply and demand of data necessary to secure the future of our planet. This will be the second Eye on Earth Summit, and will bring together representatives from government, UN agencies, non-governmental organizations (NGOs), the private sector, academia and civil society to focus on closing the data gap for environmental, social and economic data to address sustainable development. The Summit aims to identify solutions for greater access to and sharing of data, providing policymakers with timely, actionable information for the critical decisions that will implement the post-2015 development agenda. Sessions during the event will explore new resources, like crowd-sourcing and citizen science, and cutting-edge technologies. The Summit is being overseen by Eye on Earth, a collaboration of the Abu Dhabi Environment Agency’s Abu Dhabi Global Environmental Data Initiative (AGEDI) and the Eye on Earth Alliance, a partnership of organizations including, inter alia, the UN Environment Programme (UNEP), the Group on Earth Observations (GEO), the International Union for Conservation of Nature (IUCN) and the World Resources Institute (WRI).
