 The agricultural land area on earth, estimated to be about 5 thousand million hectares, is affected by degradation at a rate of about 5 to 7 million hectares per year, according to the Food and Agriculture Organization (FAO) of the United Nations (UN). Three quarters of these degraded lands are located in developing countries. Erosion is the most common type of soil degradation, accounting for 84% of the affected area.
The FAO and the International Atomic Energy Agency (IAEA, Vienna), celebrated recently the 2015 International Year of Soils (IYS 2015) declared by the 68th UN General Assembly (A/RES/68/232). The major specific objectives of the IYS 2015, as indicated by the FAO/IAEA, are to raise full awareness among civil society and decision makers about the profound importance of soil for human life, and educate the public about the crucial role soil plays in food security, climate change adaptation and mitigation, essential ecosystem services, poverty alleviation and sustainable development.
The talk will address the investigation of soil sedimentation and erosion by Nuclear Techniques using Fallout Radionuclides (FRNs), and in particular, the investigations in this field carried out at the University USTHB of Algiers and its recent cooperation with the University of Valencia (Departamento de Física Atómica Molecular y Nuclear and IFIC-Laboratory of Environmental Radioactivity) funded by Catedra Unesco and Severo Ochoa grants.
