Call for independent scientists to join the UNCCD Science-Policy Interface | Closed as of 26 March 2025

The UNCCD COP16 took place in Riyadh, Saudi Arabia in December 2024. Its impact has been tremendous, with governments pledging scale up their efforts to address land degradation and enhance resilience to drought. Those pledges also embraced an ambitious science agenda, and the scientific community is stepping up to meet the challenge.

Central to this will be the future work of UNCCD Science-Policy Interface (SPI), which provides the best opportunity for global scientists to ensure that efforts to combat land degradation and drought are grounded on solid evidence. To meet these needs, the UNCCD is issuing an Open Call for independent scientists willing to support policy makers and practitioners achieve the vision and ambition expressed by countries at COP16.

Who serves on the SPI and what is needed?     

Today more than ever there is an urgency of translating scientific findings into policy and practice. The work of the SPI over the next two years will help policy makers and practitioners advance in how we address land system challenges and build resilience of communities and ecosystems in a rapidly changing world.

Specifically, your expertise is needed to:

• Contribute to the next Global Land Outlook, the UNCCD flagship report
• Contribute to the development of other products providing scientific support for the UNCCD
• Collaborate with other intergovernmental science bodies and panels as appropriate

As emphasized by the UNCCD Executive Secretary Ibrahim Thiaw, "Scientific and traditional knowledge, actionable data and interdisciplinary collaboration are indispensable for addressing land degradation and building community and ecosystem resilience to drought." 

What has SPI accomplished so far?

The SPI has been central to UNCCD efforts to underpin policy development with sound science since 2013. Over 100 experts with a wide range of disciplinary expertise from countries all over the world have served on the SPI. The work of the SPI has scientifically framed the global approach to addressing land degradation under the 2030 Agenda’s SDG Target 15.3 known as Land Degradation Neutrality, and explored the nexus between land and drought so that resilience can be enhanced. During the 2022-2024 period the SPI accomplishments included technical reports resulting from scientific assessments on aridity trends, projections and impacts and sustainable land use systems.

UNCCD Chief Scientist Dr. Barron Joseph Orr emphasized the urgent need for experts skilled in translating science into language an informed public and policy makers can readily understand and use. “The impact of the SPI's voluntary efforts on the world is beyond measure. Members are certainly top scientists in their given fields, but also exceptional communicators. Our objective is to put a human face on land degradation and drought, which is why these experts hail from across the globe and cover not only the biophysical aspects of environmental change, but the economic, social and cultural dimensions as well.”

How does the SPI function?

The UNCCD Science-Policy Interface is comprised of 35 experts (25 independent scientists, five science delegates and five observers). The independent scientists are recruited through a global Open Call and selected by the Bureau of the UNCCD Committee on Science and Technology (CST) on the basis of scientific merit and experience in interfacing science and policy, taking into account career stage as well as gender and regional and disciplinary balance. The five science delegates are elected by each region to serve on the CST Bureau and the SPI. Four observer organizations selected by the CST Bureau following an open call to UNCCD-accredited United Nations and other intergovernmental organizations based on their contribution to the implementation of the UNCCD. The fifth observer represents civil society organizations and is nominated by the UNCCD Civil Society Organizations Panel.

The SPI is co-chaired by the Chair of the Committee on Science and Technology and an independent scientist elected by SPI members. Participation is voluntary and is governed by the Bureau of the CST supported by SPI governance documents which outline the roles and responsibilities of all members and observers. Most of the work of the SPI is conducted virtually, with tasks covered by different working groups. Past members have reported committing as much as 20 per cent of their time to deliver on the work programme of the SPI developed by the Parties to the Convention.
