Land and water management

Sustainable management of agricultural land and water is fundamental to global food security, especially in the face of climate change and increasingly erratic weather. Using nuclear technologies, we develop sustainable land and water management practices that contribute to increasing global agricultural production and food security while conserving natural resources.

  • Agricultural water management

    Agricultural water management

    Approximately 70 per cent of global freshwater consumption is used in the agricultural sector, yet water use efficiency in many countries is below 50 per cent. Nuclear and isotopic techniques provide data on water use including losses through soil evaporation and help optimize irrigation scheduling and improve water use efficiency. Read more →

  • Soil fertility

    Improving soil fertility

    Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact. Read more →

  • Soil erosion

    Soil erosion control

    Soil erosion is a major worldwide threat to agro-ecosystem sustainability and land productivity. Fallout radionuclides and stable isotopes are used to measure magnitudes and sources of soil erosion, which can be controlled through efficient soil conservation practices. Read more →

    Crop nutrition

    Crops need nutrients for satisfactory growth and quality production. Isotopes help improve crop nutrition and identify crops well-adapted to low soil fertility or particularly efficient at utilising nutrients. This is crucial to optimize yield and quality and to improve the crops’ resilience to climate change. Read more →
