    The session “Irrigation for a Resilient and Sustainable Food-Energy-Water Nexus: Science, Technology and Innovation” sets the scene for discussing a sustainable irrigation in a changing world. This scenario is based on the integration of applied and basic research, which enables irrigation’s science, engineering, and design to revolutionise “again” food production with a clearer purpose of preserving water, energy, and ecosystem services:

    On the one hand, water demands for irrigation have steadily increased since the last decades of the twentieth century and has created conflicts among water users over a finite water resource jeopardising food and energy security. Additionally, projected climate change foresees warmer temperatures and shifting precipitation patterns which altogether will modify stationary assumptions used to manage water supply, increasing water demands, shifting cropping regimes, and triggering volatile markets and socioeconomic responses across the world. Consequently, soil and water productivity could be drastically reduced and thus, food, energy, and ecosystem services, too.

    On the other hand, technological developments and innovation on monitoring and predicting future food, water, energy, and ecosystems states highlight the role irrigation may play in creating a resilient agriculture to a volatile and complex environment. The following questions need to be addressed: (1) How water and natural resources will be managed for the sustainability of irrigated agriculture? (2) How well irrigated agriculture will adapt to water scarcity scenarios? (3) How information technologies and innovation are contributing to integrate complex systems (i.e. FEWES), maximise food production, optimise water and energy consumption and preserve the ecosystem services? A key element in answering such questions has been and will be the improvement of water, energy, and fertiliser use efficiency. The increase of water, energy, and fertiliser use efficiency, the accurate estimation in evapotranspiration, and the maintenance of the agroecosystem productivity and ecosystem services will be key topics in the session. Likewise, the use of other water resources such as treated wastewater, both from industrial and domestic origin, is becoming a source for irrigation in semi-arid and arid regions where the future of irrigated agriculture is threatened by existing or expected water shortages of freshwater and rising concerns of potential water quality hazards to the environment and/or humans.

    UNU-FLORES PhD researcher Agossou Gadedjisso-Tossou will be delivering an oral presentation on the “Potential of Deficit and Supplemental Irrigation under Climate Variability in Northern Togo, West Africa” at this session.

    In addition, he will also be presenting a poster in the session “Soil Hydrology and Irrigation in Arid Environments” on the “Impact of Irrigation Strategies on Maize (Zea mays L.) Production in the Savannah Region of Northern Togo (West Africa)”.


    Background

    The EGU General Assembly is a prominent annual event that brings together geoscientists from all over the world into one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience. It attracts over 14,000 scientists from all over the world, of which more than half are early career scientists.
