ENSO-driven temperature variability shifts the altitudinal frontier of dengue risk in the Andes

Adrià San-José · Daniela Puentes · Rachel Lowe · Mauricio Santos-Vega

Abstract Despite the high burden of dengue in Latin America, high elevations have historically protected megacities such as Mexico City, Quito, and Bogotá. Climate change is expected to shift elevational suitability frontiers, yet the mechanisms governing disease expansion into highland regions and the timescales over...

Optimal Sizing of Hybrid Renewable Microgrids and Performance Evaluation of Electric Boats as an Alternative for River Transport in Colombia’s Pacific Region

John Barco-Jiménez · Francisco Eraso-Checa · Héctor Mora

In the Latin American Pacific region, rivers are the primary transportation routes for isolated and non-interconnected areas; however, river transport relies heavily on fossil fuels, resulting in high operating costs, CO2 emissions, and energy dependence. To address this challenge, this study proposes a methodology for...
