In recent years women have overtaken men as the majority on allotments and community gardens. These spaces for growing fruit and vegetables to eat at home have been peaceful places that provide families with healthy food. Datshiane Navanayagam talks to two women from Kenya and Ukraine about the appeal of these plots.
JC Niala is a writer, academic and creative from Kenya who has written about the history of allotments. Alongside Greenpeace, she has co-created ‘The Waiting List’, an allotment-sized artwork highlighting the significant demand and lengthy waiting lists for allotments.
Olia Hercules is a Ukrainian cook and author of the award-winning Mamushka cook book. Raised in rural Ukraine she later moved to London where she missed the fresh tastes of homegrown food. This led her to start the lengthy process of securing an allotment, which she says helps make a place feel like ‘home’, particularly during times of war and displacement.
They've written essays for a book celebrating allotment life called This Allotment: Stories of Growing, Eating and Nurturing.

Ella Al-Shamahi speaks to two of the first generation of women to ever fly F16s, Manja Blok for the Netherlands Air Force and Heather Penney for the US Air Force.
Manja Blok was the first female operational F-16 fighter pilot in the world. After taking the aviation exam at 19, Manja was told she was unfit to become a pilot and pursued a career as a beautician instead. She tried again at 22 and in 1991, made her F-16 debut in a career that lasted a decade and paved the way for women behind her.
Heather Penney joined the US Air Force in the late nineties, after Congress lifted the combat exclusion for women in aviation in 1993. Six months after becoming qualified for combat, Heather was assigned a mission on September 11th 2001 during the attacks in New York and Washington D.C, to intercept hijacked Flight 93.
