Concerning trend shown in the Earth Overshoot Day chart (1971-2025). The date moves earlier each year, with 2025 at 1.8 Earths indicating unsustainable resource use. Over-consumerism is a key driver. Super rich should reduce their carbon footprint.

I’m having trouble separating natural forests from plantations in my LULC maps using GEE—they often get merged into same class.I want to separate them using unsupervised classification only. What additional data, indices or processing steps would you recommend to distinguish them more reliably?

While analyzing FAO WaPOR Biomass data, I noticed a striking pattern along a river: one bank shows high vegetation growth, the other much lower. Remote sensing (RS) data reveals these stark differences in Total Biomass Productivity (TBP), possibly due to irrigation, soil type, or groundwater. #IWMI

Most rivers, especially in remote or rural areas, have no streamflow gauges. That makes it hard to predict floods, manage water or plan infrastructure. Researchers use LSTM to estimate upstream flow based on observed downstream flow. @ciroh.bsky.social
