Nuclear Techniques for a Better Understanding of the Impact of Climate Change on Soil Erosion in Upland Agro-ecosystems (D15017)

CRP at a Glance

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 Component

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 the CRP objectives.

CRP Overall Objective

Improving existing nuclear techniques to contribute to a better understanding of the impact of climate change on soil degradation in upland agro-ecosystems

Specific research objectives

  1. Development of nuclear techniques to assess the impacts of changes on soil erosion occurring in upland agro-ecosystems
  2. Distinguish and apportion the impact of climate variability and agricultural management on soil erosion in upland agro-ecosystems

Expected research outcomes

Support sustainable management of soil resources of fragile upland agro-ecosystems

Criteria for CRP participation

- Participants should have considerable research experience on land management and its impact on soil erosion/sedimentation

- Participants should have experimental sites located in agricultural uplands 

- Participants should have at least one of the following analytical facilities and at least 5 years of research experience in using these analytical facilities:
