2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
The Montado/ Dehesa Agroforestry system contributes to carbon sequestration in Spain and Portugal. The SmartAG app helps in monitoring and management of these systems, providing data available to farmers, producers, and stakeholders.
2.2 Detailed description of the Technology
Description:
The SmartAG model is mainly applied in the Montado (Portugal) and Dehesa (Spain) agroforestry systems which serve as a biodiversity oasis in the
Mediterranean region. They are currently being heavily impacted by climate change.
It contributes to achieving carbon sequestration potential. The SmartAG model is also applied in agriculture systems in Portugal, Spain, Greece, The Netherlands, Indonesia and Ukraine. Nevertheless, it can be applied in any part of the world. The SmartAG app provides accurate Agricultural Climate Services on a large-scale, available to farmers, producers, and stakeholders. The model analyzes agronomic anomalies to reduce CO2 emissions and promote CO2 sequestration in the soil, via remote sensing. Additionally, it seeks to remotely analyze farms by evaluating the spatiotemporal dynamics occurring in agroforestry activities for the same purposes.
Through data collection on land use, mapping, remote sensing and in situ data collection, an assessment of the initial state of the farm is carried out, along a carbon balance, to establish a reference scenario (baseline year). Future projections are made, and recommendations formulated.
Users appreciate this methodology because it helps them conserve or increase current carbon stocks, potentially creating a new source of income through the sale
of carbon credits. SmartAG is a highly user-friendly app which records georeferenced evidence of existing conditions and activities. It facilitates a transparent and participatory process in agroforestry ecosystem management.
SmartAG automatically processes data from Sentinel-1 and Sentinel-2 data, and LST data for thermo-climatic zoning. These data: i) allow monitoring, reporting and verification of farms; ii) provide machine learning capabilities in agroforestry and environmental data.
Based on Sentinel data, spectral vegetation indices are calculated to identify: i) crop anomalies related to soil-water-plant; ii) management zones to define different land uses, the selection of sampling locations and sensor installation sites, water sampling locations, and identification of species for biodiversity quantification.
The Montado/Dehesa is a slow-developing and very complex agroforestry system meaning that differences will be observable only at the end of a year or longer. In addition, it is a highly stratified system, consisting of a complex arboreal structure with trees of different ages, shrubs, and herbaceous vegetation. Given the limitations of Sentinel-1 and Sentinel-2 satellites it is essential to record georeferenced evidence of these. Using SmartAG app developed by AgroInsider allows the collection of georeferenced evidence (e.g., photos, audios, and videos) of
the vegetation structures, as well as documenting evidence of processes occurring such as ecosystem services and biodiversity. Georeferenced evidence is automatically uploaded into the system.

4. Technical specifications, implementation activities, inputs, and costs
4.1 Technical drawing of the Technology
Technical specifications (related to technical drawing):
The LMT will be implemented on a farm with montado/dehesa (minimum area of 100 ha). Satellite data is used to characterize land use. After identifying the montado/dehesa area, field sampling is conducted. These data, along with satellite imagery, will be used to calculate the total CO2eq stock (above and below ground biomass) and estimate CO2eq sequestration. Farmers are encouraged to enhance LMT effectiveness, notably by engaging in ecosystem-value activities such as avoiding soil disturbance to preserve soil organic matter, increasing tree density, and maintaining water mirrors. Farmers will record georeferenced evidence of improvement activities and existing biodiversity in the montado and in other areas of the farm using the SmartAG developed by AgroInsider. This app will allow to monitor, report and verify carbon stocks through weekly alert reports, enabling the identification of carbon anomalies/losses over time and space.

Comments and further specifications on biodiversity:
The Agroforestry system Montado, in Portugal, and Dehesa, in Spain, is a High Nature Value system characterized by a high complexity because of the interactions between climate, soil, pasture (natural pastures, fertilized natural pastures, and sown biodiverse permanent pastures rich in legumes), trees (e.g., pure or mix stands of cork oak, holm oak, stone pine), and animals (e.g., sheep, pigs, cows, goats). Montado/Dehesa is one of the most prominent and best preserved low-intensity farming systems in Europe. The integration of traditional land-use and biodiversity conservation that is characteristic of this system is an exemplar for the wise management of the countryside.
