Fair Markets and Resilient Supply Chains: Designing Sustainable Intermediation for Rural Communities
Sustainable Development, EarlyView.ABSTRACT Agriculture in Ecuador's communes faces significant economic, social, and environmental challenges, intensified by supply chains dominated by traditional intermediaries. The lack of context‐specific sustainability studies further increases the vulnerability of smallholders.

Three-dimensional coal seam modeling of fully mechanized working face based on transparent geology
Gong-kuang zidonghua, 2022 The three-dimensional coal seam modeling method based on transparent geology is an effective way to indirectly solve the problem of coal rock identification. Most of the existing three-dimensional coal seam modeling methods focus on the expression of spatial three-dimensional entities. There is a lack of research on the dynamic change of coal seam roof
