Soil degradation, characterized by erosion, nutrient depletion, compaction, and climate variability, profoundly threatens sustainable agriculture and food security worldwide. Agroforestry systems, which synergistically integrate trees, crops, and livestock, offer a regenerative approach to soil conservation and ecosystem restoration. Among the tree species utilized, Eucalyptus has become one of the most widely adopted in agroforestry systems due to its rapid growth, ecological adaptability, and multifunctional uses ranging from timber and fuelwood to environmental services. This chapter advances the discourse by introducing Agroforestry 2.0, an innovation-driven paradigm that merges ecological knowledge with frontier technologies to strengthen soil conservation in Eucalyptus-based systems. Using tools such as geographic information systems (GIS), remote sensing, the Internet of Things (IoT), artificial intelligence (AI), digital twin simulations, and bioinformatics, these combined strategies allow for accurate assessments, flexible land-use planning, and up-to-date monitoring of soil health and fertility. Drawing from case studies across tropical and semiarid regions, this chapter demonstrates how technology-enhanced Eucalyptus agroforestry can mitigate degradation, increase microbial diversity, and optimize nutrient cycling within multifunctional landscapes. Furthermore, it explores the socioeconomic and institutional enablers needed for large-scale adoption among smallholders. Ultimately, this chapter envisions a future in which tech-enabled Eucalyptus agroforestry catalyzes climate resilience, ecosystem regeneration, and inclusive rural development.
