- A 2023 study was recently awarded the Cozzarelli Prize from the Proceedings of the National Academy of Sciences for its work identifying “forgotten” food crops in sub-Saharan Africa that may be more resilient to climate change than the region’s current staple crops of maize, rice, cassava and yams.
- The study found that West Africa and Central Africa would experience the largest decrease in suitability for current staple crops by 2070, and that maize was the most vulnerable of the staples.
- In addition to identifying 52 food crops that will likely be better-suited to the region’s future climate — and which have more nutritional value than staple crops — these researchers have already succeeded in introducing some of the overlooked crops to local communities.

- Researchers at the University of Arizona analyzed 20 years of satellite data to understand how different Amazon forest ecosystems respond to drought. They found that variations in water-table depth, soil fertility and tree height influence forests’ response to droughts.
- In the southern Amazon, experts observed a strong relationship between groundwater availability and the forests’ drought resilience. But the situation was more complex in the northern Amazon, where drought vulnerability depended on a combination of factors, including water availability, soil fertility and tree height.
- The study suggests scientists may have overestimated the risk of drought-related tree death — and the amount of carbon released into the atmosphere as a result — in the southern Amazon. However, long droughts, like the current one across the Amazon, can push these forests to the brink of collapse.
- The researchers created a map of drought resilience across the Amazon Basin, which shows that forests at high risk of deforestation are also most vulnerable to drought. These forests also play a key role in regional weather patterns by feeding the “atmospheric river” that brings rainfall to major agricultural areas.

- An artificial intelligence tool trained to track gold mines through satellite imagery found that the deforestation linked to the activity doubled in the Amazon Rainforest from 2018 to 2023.
- Mines are widespread in the biome, affecting especially Brazil, Guyana, Suriname, Venezuela and Peru.
- The spread of gold mines followed a sharp increase in the price of the metal, which nearly doubled since 2018.
- In Brazil, the federal government has succeeded in reducing the rate at which illegal mining is expanding inside Indigenous territories, but still struggles to block its spread outright.
