Brazil’s antitrust regulator, CADE, decided to suspend the Amazon soy moratorium from Jan. 1, 2026.

Depending on the probe’s course of action, this could dismantle one of the nation’s most important private sector pacts credited with slowing deforestation of the rainforest for soy plantations.

As forests are cut down, butterflies are losing their colours
The insects’ brilliant hues evolved in lush ecosystems to help them survive. Now they are becoming more muted to adapt to degraded landscapes – and they are not the only things dulling down

Food must be taken seriously as an environmental problem.

It uses ~38% of Earth’s land, drives ~70% of water use, and emits ~22-34% of greenhouse gas pollution globally.

And beef and dairy alone drive a huge proportion of this.

But there are solutions. Lots of them.

Trophic rewilding depends on the assumption that replacing lost megafauna with alternative species can generate similar benefits. This new review by Bescond-Michel et al. challenges that belief. 🌏🌐🧪
Harms of introduced large herbivores outweigh benefits to native biodiversity - Nature Communications
Using impact assessment frameworks, this study shows that the introduction of large mammalian herbivores outside their native range has predominantly caused negative impacts on native biodiversity globally. The authors advise caution regarding their further intentional introduction for conservation purposes.

🇬🇪Georgia’s Anti-Corruption Bureau (ACB) might sound like a graft-busting agency, but under Razhden Kuprashvili it has become a political weapon.
Georgian Dream is using it to wage a repressive crackdown on civil society, silencing NGOs and opposition voices.

Are you a social scientist that wants to learn R?

Then, you may find my course "R for Social Scientists" very useful!

I designed this course to give social scientists all that is necessary to start using R in their everyday work.

Using participatory mapping and satellite-based analyses, we show that 400 Indigenous communities in the Argentine Chaco
- lost on average 21% of the forests they use
- saw a decline of up to 35% in ecosystem service provisioning
- face increasing restrictions in terms of accessing resources
