WP4 Task 4: Simulation and Analysis of biophysical effects of CC adaptation strategies using STICS model on RECORD platform and DAYCENT.

Task description:

Two IPCC (i.e., A2 and B1) emission scenarios will be selected to simulate long-term CC effects on alternative and conventional agriculture from 2050 through 2100.

Two soil-crop models, DAYCENT (Del Grosso et al., 2001) and STICS (Brisson et al., 1998; 2002; 2003; 2008), will be used.

Specifically, adaptation strategies will include new cultivars, novel and diverse crop rotations with legume, intercrops, controlled traffic, and less intensive tillage practices, which differ from conventional management practices.

Organic farming practices will also be considered for test cases where applicable.

Random changes in each management event (i.e. changing planting data and fertilization rates) that growers could adopt will be simulated. We will compare long-term changes in soil water, plant growth, water productivity, soil organic C, N loss dynamics, and GHG emissions among the selected adaptation options for the IPCC scenarios.

Effects of future rising [CO2] and other global changes (e.g., N deposition) will be simulated in adaptation scenarios.

For irrigated systems the scenario analysis will be upscaled to scheme level aided by GIS. Model results will be reported for the period 2020-2050 and 2070- 2100.

Task leader: INRA, partners involved: INRA, ETHZ, Agroscope, CSIC, U. Helsinki – Duration: M24 – M36
