The land-water nexus: improving the science-policy interface to strengthen resilience

UNCCD Science Policy Interface (SPI) – Bonn Water Network (BWN) Joint Session.
9:00-11:00 (CET), 22 March 2024
MET 2116, Langer Eugen Building, UN Campus, Bonn, Germany


Sustainable land and water management is the key to food security and the health of people and ecosystems. It is also critical to building resilience to droughts, floods and other natural disasters. Climatic changes and changes in land use and mutual interactions accelerate land degradation, making it more sensitive to the effects of droughts and floods. These dynamics can contribute to competition for resources, civil unrest and forced migration. To mark World Water Day 2024, UNCCD and the Bonn Water Network are organizing a joint event to explore the role of the science-policy interface in the land-water nexus.

The United Nations Convention to Combat Desertification (UNCCD) is a global vision and voice for the conservation of land and water resources. In addition, as an international legal instrument entered into force by 197 parties, it unites countries, companies and all other stakeholders in working together to fight desertification, land degradation and mitigate the effects of drought; they maintain ecosystem health and improve living conditions for people. The Convention's Science Policy Interface (SPI) works to translate scientific findings into policy options to improve land restoration, sustainable land and water management and build drought resilience to advise the Convention's Committee on Science and Technology (CST) to guide Parties towards Land Degradation Neutrality ( LDN) until 2030.

Founded in 2020, the Bonn Water Network (BWN) brings together expertise from Bonn in water-related research, training and practice. Its eleven members, made up of research institutes, UN institutions and civil society organizations, are active in Bonn and around the world. BWN is a knowledge hub, rooted in the international sustainability environment of the city of Bonn, and works on a wide range of water topics from different scientific and stakeholder perspectives to achieve sustainable and inclusive water solutions.


This joint session will provide an opportunity for SPI and BWN to exchange relevant activities, research results and case studies that could benefit the future work of SPI as well as the activities of BWN institutions. Contributions will focus on the role of the science-policy interface in understanding and managing the land-water nexus.
