Smallholder farmers produce 70% of Africa's food. They're providers and entrepreneurs in their communities. Yet many lack access to the seeds, tools, and training needed for reliable harvests.

The world has lost Dr Jane Goodall. At 91, she was still travelling, still speaking, still urging us to preserve the environment and protect the chimpanzees who first brought her to the world’s attention. Her death is a loss not only to those who knew her but to the world as a whole.

Today we received the sad news that Jane Goodall has died at the age of 91.
