Assessment of Sentinel‐2 and Landsat‐8 OLI for Small‐Scale Inland Water Quality Modeling and Monitoring Based on Handheld Hyperspectral Ground Truthing

open access: yesJournal of Sensors, Volume 2022, Issue 1, 2022., 2022
This study investigates the best available methods for remote monitoring inland small‐scale waterbodies, using remote sensing data from both Landsat‐8 and Sentinel‐2 satellites, utilizing a handheld hyperspectral device for ground truthing. Monitoring was conducted to evaluate water quality indicators: chlorophyll‐a (Chl‐a), colored dissolved organic ...

Remotely sensed assessment of increasing chronic and episodic drought effects on a Costa Rican tropical dry forest

open access: yesEcosphere, Volume 12, Issue 11, November 2021., 2021
Abstract Tropical dry forests (TDFs) have experienced pronounced droughts and increased temperatures for the last century. To assess whether these climatic shifts have influenced dry forest vegetation and ecosystem functioning, we integrated ground observations from a Costa Rican long‐term forest dynamics monitoring plot with remotely sensed measures ...

The Role of Differential Ablation and Dynamic Detachment in Driving Accelerating Mass Loss From a Debris‐Covered Himalayan Glacier

open access: yesJournal of Geophysical Research: Earth Surface, Volume 126, Issue 9, September 2021., 2021
Abstract Sustained mass loss from Himalayan glaciers is causing supraglacial debris to expand and thicken, with the expectation that thicker debris will suppress ablation and extend glacier longevity. However, debris‐covered glaciers are losing mass at similar rates to clean‐ice glaciers in High Mountain Asia.

The end of the rural/urban divide? Migration, proletarianization, differentiation and peasant production in an ejido, Central Mexico

open access: yesJournal of Agrarian Change, Volume 21, Issue 2, Page 332-355, April 2021., 2021
Abstract This article explores the relations between agricultural production, international migration, wage labour and processes of differentiation among peasant households. It does so based on the analysis of the ejido Jesús María in the northeast of the state of Guanajuato, Central Mexico. The history of this ejido and how Mexican neoliberal policies
