Nibbles: Deforestation, Mayan collapse, Agroforestry, One Acre Fund, School gardens

Cutting down forests worsened ancient Mayan droughts.
And (among other things) did for the Maya.
And despite the Mayan end of the world being near, the French are revitalising agroforestry.
The Financial Times wrote about One Acre Fund’s work to reduce agrobiodiversity in Kenya, then put it behind a paywall (for me). So One Acre Fund sprung it.
School gardens continue to flourish in some places.
