Resumo(s)
The Island of S. Tomé, located in the Gulf of Guinea, is part of one of the smallest countries on Earth,
registering only 163,784 residents. It is also a very biodiverse equatorial environment, discovered by the
Portuguese, in 1470. Exuberant native vegetation covers most of the island, even though it has suffered
logging in order to give way to sugar plantations between 1494 and 1610, as well as coffee and cocoa
plantations from 1780 onwards. Current submission stems from research conducted in the now independent
country, in 2019, by the University of Lisbon. The objective was to find out if the depredation
suffered in colonial times had any significant impacts on the environment, on food security and on the
wellbeing of the Gulf of Guinea islanders. Methodology was three-fold: (1) examination of old manuscripts
and recent literature about the history of plantations, so as to enumerate the plant species existent
in the beginning of colonisation and the ones introduced during colonisation; (2) survey to fifty urban
residents, in modern times, so as to evaluate the economic and environmental impacts of Portuguese
presence and economic management; (3) identification of flora. The in-depth interviews aimed four
focus groups: (i) fruit, roots, staples, spices, and medicinal plant traders, found in markets and along
the streets (74%); (ii) urban and peri-urban farmers that cultivated food plants, spices and medicinal
flora (20%); (iii) traditional healers also involved in flora cultivation (4%); (iv) one touristic guide that
traded medicines grown and processed in a Botanical Garden, located further inland (2%). The survey
accounted for 111 botanical species, some of which were native. The hope is to contribute for a better
understanding of the evolution of flora consumption in Africa, and to explain why there was no serious
depredation in this Gulf of Guinea Equatorial environment.
