Because of the high vulnerability of agriculture, which is highly climate-dependent, farmers need crops and agricultural systems that consider the climate change effects. The IPCC defines the risk of climate-related impacts as the results of the interaction of climate-related hazards with the vulnerability and exposure of systems, and also explain how the adaptation of a system can modulate this vulnerability, and also reduce exposure to different hazards. In this context, the LIFE Nadapta project includes, among a number of strategies for improving the adaption of the region (Navarre, SPAIN) to climate change, an adaptation strategy intended to increase the resilience of agrosystems, especially in relation to one of the most important production factors: the agricultural soil.
Considering the diversity of this region and the variety of agricultural practices spread throughout it, the work was conducted at three levels: First, a vulnerability study of agricultural soils was conducted at the regional level after zoning out the region into 12 homogeneous areas, identifying critical soil characteristics in each of them. Second, a network of up to 150 control plots was created, in which a number of indicators related to vulnerability and resilience were analyzed, encompassing the diversity of both soil types and management systems. Finally, threshold and target values of each indicator will be set for each area and monitored along the 8 years of the project.
The proposed set of indicators, defined according to climatic drivers and the chains of impact they generate, is classified into two levels. Those related to the intrinsic characteristics of the soil, vulnerability indicators, and those potentially modifiable by management, dynamic indicators, which allow monitoring the evolution of this vulnerability. SOC is one of the main indicator proposed for long-term monitoring of the agrosystems vulnerability, as well as water retention capacity, bulk density and structural stability.
Rodrigo Antón is PhD student at the Soil Science lab at Universidad Pública de Navarra (UPNA). He joined UPNA in 2013 after completing his postgraduate education at Institut Agronomique Méditerranéen de Montpellier (France) and he has since then participated in a number of projects related to soil quality and management.
