On 1 March 2019, under Resolution 73/284, the United Nations General Assembly proclaimed 2021–2030 as the United Nations Decade on Ecosystem Restoration (UN Decade) with the primary aim to ‘prevent, halt and reverse the degradation of ecosystems worldwide’. The UN Decade is co-led by the United Nations Environment Programme (UNEP) and the Food and Agriculture Organization of the United Nations (FAO) in close collaboration with the secretariats of the Rio Conventions, other relevant multilateral environmental agreements and entities of the United Nations system together with a wide range of global, national, and local partners. To date, over 200 partners have joined formally the UN Decade, from global entities to local ‘Actors’. As per the strategy of the UN Decade, an Advisory Board is the main external body of the UN Decade’s governance structure. The Board’s main objective is to amplify the UN Decade’s key messages, link to their respective networks, and offer relevant perspectives and schools of thought in response to the challenges and barriers for implementing the UN Decade. With the board’s first term coming to an end in April 2023, this call invites for applications to join the board for the next term May 2023 to April 2025.
