Description

Upland agro-ecosystems - defined as the less favoured higher altitude environments including areas with low soil quality and/or limited access to water - will face three major challenges related to food security and climate change in the coming decades:  increasing food production while protecting against soil erosion, adapting to climate change impact on soil resource, and contributing to climate change mitigation. This CRP aims to (i) develop combinations of nuclear techniques to assess impacts of changes on soil erosion, and (ii) distinguish and apportion impacts of climate variability and agricultural management on soil erosion in upland agro-ecosystems.Nuclear techniques including Fallout Radionuclides (FRNs) such as caesium-137 (137Cs), lead-210 (210Pb), beryllium-7 (7Be) and plutonium-239 and 240 (239+240Pu), Compound-Specific Stable Isotope (CSSI) techniques based on the measurement of carbon-13 (13C) natural abundance signatures of specific organic compounds (i.e. fatty acid) and Cosmic Ray Soil Moisture Neutron Probe (CRNP) will be used to fulfil these specific objectives.

Objectives
