Right! Of 770,000 tons of rice imported, only 100,000 tons are for human consumption

Interesting report. But, as far as I know, Japanese strongly prefer Japanese rice. This stems from their belief in the superior quality of local rice and the strong influence of the Japan Agricultural Cooperatives, which restrict imports—contributing to the recent rice crisis in Japan.

🆕 The first stunning images from our groundbreaking #Biomass satellite mission have been released – they mark a major leap forward in our ability to understand how Earth’s forests are changing and exactly how they contribute to the global carbon cycle 🌳🌍

www.esa.int/Applications...

This image features part of Bolivia. This vibrant image was created using the radar instrument’s different polarisation channels, with each colour revealing distinct characteristics of the landscape. For instance, green hues mainly represent rainforest, red hues forested floodplains and wetlands, and blue–purple is indicative of grasslands, while black areas are rivers and lakes. The image spans approximately 90 km along the Biomass satellite's flight path (length) and 60 km across in width, with north oriented to the right.

Bad papers can do more harm than none...

Definitely quality > quantity. But the challenge lies in how to evaluate 'quality'. I've come across poorly written papers in top journals and seen poor papers get significant citations.

📣In our new paper we analyzed the impact of #Landsat and #Sentinel-2 🛰️ #satellite data density and SMA endmembers on trends in #grasslands ground cover:
- for monthly composites data density is irrelevant
- correct endmember definitions are critical‼️

Observations from 3 #Sentinel2 satellites! Increased revisit frequency. Terrific news!
“This configuration will enhance the availability of Sentinel-2 data, with additional Sentinel-2 observations on the same relative orbit, occurring 2 days apart from Sentinel-2B and 1 day apart from Sentinel-2C.”

New #IEEE GRSM paper on responsible #AI for #EarthObservation! AI for EO data analysis holds great promise in addressing global challenges but simultaneously needs a careful examination of the dimensions of responsibility. We reviewed them in this #openaccess article: doi.org/10.1109/MGRS...

Diagram showing the main building blocks of responsible
AI in EO. Mitigating unfair bias, securing AI, preserving (geo)privacy, and addressing ethical concerns outline the considerations necessary for
implementing responsible AI methodologies within the fields of EO.
Social good presents the opportunities and goals related to how a
responsible AI system can effectively be utilized to make a positive
difference in people’s lives.
