3G Internet Diffusion and Secondary Education Attainment: Evidence of Opportunity Cost in Vietnam

open access: yesReview of Development Economics, EarlyView.
ABSTRACT Mobile internet diffusion has led to significant societal and economic transformations since its early diffusion, especially in the Global South. This has implied changes in human capital formation, particularly through education, and has reshaped the trade‐off between education and employment, especially among the younger population.

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis

open access: yesReview of Development Economics, EarlyView.
ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.

Machine learning‐based prediction of cereal rye cover crop biomass across diverse agroecosystems

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Accurate operational predictions of cereal rye (Secale cereale L.) biomass are critical for quantifying the agroecosystem services provided by cover crops and for guiding growers’ management decisions for subsequent cash crops. In this study, we developed machine learning‐based biomass prediction models using two advanced gradient‐boosted tree

Impact of Spatial Scale on Optical Earth Observation‐Derived Seasonal Surface Water Extents

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Landsat‐derived products are the most prominent, publicly available sources of large‐scale surface water extent data. However, few studies have assessed the limitations of spatial scale on such products. Here, we mapped seasonal surface water extents utilizing high‐resolution (4.77 m) PlanetScope Basemap imagery and machine learning.
