This 20th issue of ÍNDEX Arte Contemporáneo features on its cover the work of Fernando Falconí, whose cyanotype series Cartografías para un árbol de agua —both cover image and visual essay of the issue— transforms old maps of rivers such as the Guayas or the Amazon into trees and vegetal patterns, in order to question the relationship between science, techné, landscape, and memory. In the Art Themes section, Tiffany Garzo offers a reading of My Dinner with André through the lens of biopolitics and societies of control; Belén León-Río explores the energy of matter as a force of consciousness within creative processes; María Fernanda Gallardo reflects on walking art as a device to subvert hegemonic imaginaries of the Andes and their cartographies; and Federico Del Giorgio Solfa critically reviews contemporary debates on research in design. The issue closes with the Curatorial section, featuring a text by Giada Lusardi on Estiaje, an exhibition by Juana Córdova, Irina Liliana García, and Pamela Suasti, where collaborative practices and organic materials activate a poetics of waiting, ecological fragility, and care.
