Background

HoliSoils focuses on forest soils and considers them to be an essential—but often neglected—part of forest ecosystems, with abundant biodiversity determining overall ecosystem functionality and provision of ecosystem services (e.g. timber resources, water supply, carbon sequestration). The overall goal of HoliSoils, an EU Horizon 2020 project, is to develop a harmonised soil monitoring framework and to identify and test novel holistic soil management practices that will help to mitigate climate change, adapt forests to cope with climate change, and sustain provision of forest ecosystem services essential for human livelihoods and wellbeing. To this end, HoliSoils incorporates novel methodologies and expert knowledge on analytical techniques, data sharing, soil properties, and model development in order to develop tools for soil monitoring, refine greenhouse gas (GHG) assessment of the Land Use, Land Use-Change and Forestry (LULUCF) sector, enhance efficiency of GHG mitigation actions, and improve numerical forecasting of soil-based mitigation, adaptation and ecosystem services.

Objectives

Advance knowledge of forest soil properties, processes, biodiversity, and activity of soil microbiota, all of which influence soil-based ecosystem services (wood production, reduction of GHG emissions, water supply, soil nutrient retention, avoidance of land degradation) in organic and mineral soils;

Develop and improve state-of-the-art soil models, harmonise them into a monitoring framework for estimation of carbon (C) and GHG fluxes, nitrogen (N), and base cation stocks in forest soils, and integrate them into forest ecosystem models;

Develop standardised sampling and monitoring protocols for soil sampling, GHG reporting, harmonise legacy soil data from multiple sources and make them available to end-users through a web portal, and develop and apply digital soil mapping methods to facilitate model upscaling to the European scale;

Determine effects of management on soil functionality, biodiversity, nutrient stocks, (i.e. C, N, phosphorous (P), potassium (K), magnesium (Mg), calcium (Ca), and manganese (Mn)), organic matter quality, and stabilisation processes, and integrate C and N into numerical models, and to develop holistic climate-smart forestry, taking into account soil productivity, GHG exchange, water availability, erosion, and soil resilience (avoidance of degradation), and study their soil-related climate change mitigation and adaptation potential on mineral and organic (forested peatland) soils;

Determine effects of natural disturbances on soil functioning and resilience, identify good management practices for preventing soil degradation, and map soil vulnerability;

Study the impacts, trade-offs, and synergies of climate-smart forestry scenarios for soils and forests on the Europewide GHG balance and water budget under future climate conditions and disturbance regimes;

Boost collaboration between universities, research institutes, and intergovernmental bodies such as the European Union (EU), United Nations Framework Convention on Climate Change(UNFCCC), United Nations (UN) Intergovernmental Panel on Climate Change (IPCC), and Food & Agriculture Organization of the UN (FAO), and facilitate the transfer of developed approaches, knowledge, and tools globally to operators within the forest sector via a multi-actor approach.

ISRIC Activities

  1. Review current soil sampling and monitoring methodologies used in GHG inventories and soil monitoring networks
  2. Develop resource-efficient soil sampling design, monitoring, and measurement protocols for a harmonised GHG inventory;
  3. Store shared data in a central repository;
  4. Apply upscaling methodologies for soil monitoring at test sites;
  5. Develop a web-based platform for soil information to be used by models.

Deliverables

  1. Review of soil monitoring programmes; guidelines and protocols for soil sampling, monitoring, and analyses, allowing harmonisation of a Europe-wide GHG inventory;
  2. High-resolution maps of key model inputs, to support model upscaling to the European scale;
  3. Database on harmonised soil data and associated web portal.
