Abstract:In Sub-Saharan Africa, the West African region has highly diverse agro-climatic conditions, which grant the potential for a remarkable agricultural production of a great diversity of crops. Since the 1980s, the production volumes of most crops have grown vigorously for both domestic and export markets. Traditional food crops-such as rice, groundnuts and sorghum-have been replaced by cash crops, namely cashew. Among the main cashew production areas, West Africa is the most recent and dynamic in the world, accounting for 45% of the worldwide production of cashew nuts in 2015. In consequence, cashew cultivation has acquired an important position in West African smallholder farming, providing positive economic and social effects. In this paper, we provide an overview of the cashew production system in the West African region, using Guinea-Bissau as a case study. In particular, we present some viewpoints concerning the impact of cashew production and discuss how the strong dependence on a single cash crop can compromise the local livelihoods and food security. Finally, some insights are given towards the sustainable production of cashew in the face of the recent risks affecting the agricultural sector in West Africa.

The island of Poilão in the Bijagós Archipelago, the west coast of Africa. Traditionally Poilão has been regarded as a sacred site by the Bijagó s people, and this Guinea-Bissau, is known to be an important nesting site for the green turtle Chelonia mydas, but until recently has contributed to the conservation of these turtles. However, the development of fisheries in this region is there were no quantitative estimates of the number of clutches deposited annually. In 2000 a survey was an emerging threat. To conserve this site a National Marine Park was designated in August 2000. carried out to assess the magnitude of nesting, and an estimated 7,400 green turtle clutches were deposited. Four nesting hawksbill turtles Eretmochelys imbricata were Keywords Africa, Chelonia mydas, Eretmochelys imbricata, green turtle, Guinea-Bissau, hawksbill turtle, Poilão, sea also encountered.

The sub-Saharan region holds a wide variety of indigenous plant species, still offering the possibility to discover very interesting new natural products with potential therapeutic value. Most of the African population depends on traditional medicine for primary health care, however, neurological disorders are often not considered as common diseases and many people with mental illnesses, like epilepsy, are severely affected by health-related stigma and discrimination. Epilepsy is the most common serious chronic brain disorder, estimated to affect at least 10 million people in Africa. Guinea-Bissau is located in West Africa, and its population is mainly rural with very few health services available. Since the earliest times, Guinea-Bissau flora has constituted the main source of materials used in folk medicine and the local population, who is well versed in the uses of these plants and their properties. The aim of this study was to document the existing knowledge and practices related to the treatment of neurological disorders, namely epilepsy and seizures, in Guinea-Bissau and in other West African countries. The results presented from this study provide information not only on the specific plants used to treat neurological disorders, but also on social knowledge brought in by various ethnic groups, each one having its own culture, beliefs and ways of nature appropriation. Taking into account the existing knowledge on the medicinal properties of plants for treatment of neurologic disorders, it is believed that research in the areas of ethnomedicine and ethnopharmacology in Guinea-Bissau can bring promising results capable of adding value to the very rich natural resources of this country of West Africa.

BackgroundWorldwide, governments have implemented restrictions on movement and gatherings to contain the COVID-19 pandemic. In the spirit of the Convention on the Rights of the Child, children have a right to express their opinion on matters of concern to them. The study aimed to describe and analyse how adolescents in the capital Bissau understood the unfolding COVID-19 pandemic and their lived experiences during the first 3 months of the pandemic.MethodsCollaborators identified participants in five urban areas in Bissau in June 2020. Semistructured, open-ended interviews were conducted with 30 adolescents aged 15–17 years, attending private and public schools or out-of-school. The interviews were conducted in Kriol, recorded, transcribed, translated and analysed.ResultsAll the participants were heavily affected by the confinement measures during a state of emergency. Almost all believed in the realness of coronavirus while there were some doubts about its arrival in the country. The consequences were staying at home, enforced with increased police violence. At the same time, other violence on the streets or between neighbours had decreased. A few participants said they liked staying at home because they appreciated spending more time with their families. Most participants claimed that they and their family members tried to follow preventive measures. Almost all participants voiced concerns about the worsening financial situation at home, leading to food scarcity. Nearly all the adolescents were tired of the lockdown and worried about the pandemic’s implications on their future opportunities.ConclusionsStudy participants, here adolescents in Bissau, have a clear notion of their existence and the current situation’s potential negative impact on their future. Their voices need to be heard and acted on, which may soften the lockdown’s negative impact on adolescents in Guinea-Bissau, as elsewhere.
