Historical landscape photographs have been matched with modern images and used to analyse changes in alpine glaciers, hydrology and soil erosion, and vegetation, including changes in the populations of long-lived desert succulents and savanna trees.
Repeat photography is increasingly being seen as an important tool for monitoring the impact of climate change on vulnerable species and threatened ecosystems.
South African start-up Mycominded works with fungi to develop organic alternatives to plastics.
Plastics have very short-use lives but stay in waste dumping areas for centuries.
"One of the landfills in Cape Town receives about 4200 tons of waste per day. We are not creating landfills anymore; we are literally building mountains of trash."
Mycominded is an excellent case study of how working with nature can not only heal our planet but creates sustainable and innovative business opportunities.
Nigeria’s President Muhammadu Buhari is about to take over the presidency of the Pan-African Agency of the Great Green Wall – the continent’s effort to restore degraded cropland, grazing areas and woodlands bordering the Sahara Desert. He takes over from Mohamed Ould Ghazouani, president of Mauritania.

At the same time, the government’s farmer support programmes haven’t been agile and quick enough to provide the necessary support for beneficiaries.
