2022 Symposium Scientific Programme


The purpose of the symposium is

  • To review recent development of nuclear, isotopic and related techniques to improve land and water management practices under changing climate and to minimize the impact of radiological emergences on crop production;
  • To provide information on the development of tools and technology packages to build soil resilience, adapt farming practices to the impact of climate change, as well as to nuclear or radiological emergencies; and
  • To identify knowledge gaps, research needs and new opportunities to develop climate-smart agricultural practices to build capacities and transfer of technologies to Member States.


The symposium will cover the following scientific topics related to land and water management under climate change and radiological emergences:

  • Plant nutrition and nutrient cycling for enhancing crop productivity and on-farm ecosystem services. –
    • Carbon sequestration in agroecosystems: opportunities and costs
    • Fertilizer technology: new concepts and approaches to increasing efficiency
    • Novel tracing technologies applied in nutrient cycling in agroecosystems
  • Soil conservation, land management minimizing soil erosion, land degradation, improving soil health, increasing biodiversity and crop production.
    • Latest development in soil erosion and sedimentation assessment
    • Isotopic techniques for Identifying sources and hot spot of erosion
    • Influence of climate change and agricultural practices on erosion using FRNs and stable isotopes techniques.
