UAV‐Based Precision Seed Dropping for Automated Reforestation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

open access: yesResponsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

The Global Forestation Network: Orchestrating the Financing and Development of Tree Planting Programs

open access: yesSustainable Development, EarlyView.
ABSTRACT This study introduces the ‘global forestation network’ (GFN)—an arrangement of actors that shape afforestation, reforestation, and forest restoration activities worldwide. These activities typically involve planting trees, and are motivated by supporting biodiversity, local communities, and climate change mitigation. At the GFN's core sit the ‘
