Childhood diseases remain an increasing health problem in many developing countries and also associated with an enormous financial burden. In South Africa, many people still rely on traditional medicine for their primary healthcare. However, inadequate documentation of medicinal plants used to manage childhood diseases remain a prominent gap. Hence, the current study explored the importance of medicinal plants to treat and manage childhood diseases in the North West Province, South Africa. An ethnobotanical survey was conducted with 101 participants using semi-structured interviews (face-to-face). Ethnobotanical indices such as Frequency of citation (FC), Use-value (UV) and Informed Consensus Factor (ICF) were used for data analysis. A total of 61 plants from 34 families were recorded as medicine used for managing seven (7) categories of diseases resulting from 29 sub-categories. Skin-related and gastro-intestinal diseases were the most prevalent childhood health conditions encountered by the study participants. Based on their FC values that ranged from approximately 0.9–75%, the most popular medicinal plants used by the participants were Aptosinum elongatum (75.2%), Commelina diffusa (45.5%), Euphorbia prostrata (31.6%) and Bulbine frutescens (31.7%). In terms of the UV, A. elongatum (0.75), C. diffusa (0.45), E. prostrata (0.31), H. hemerocallidea (0.19) and E. elephantina (0.19) were the dominant plants used for treating and managing childhood diseases. Based on ICF, skin-related diseases dominated with the highest ICF value of 0.99. This category had 381 use-reports, comprising 34 plants (55.7% of total plants) used for childhood-related diseases. Particularly, B. frutescens and E. elephantina were the most-cited plants for the aforementioned category. Leaves (23%) and roots (23%) were the most frequently used plant parts. Decoctions and maceration were the main preparation methods, and the plant remedies were mainly administered orally (60%) and topically (39%). The current study revealed the continuous dependence on the plant for primary health care relating to childhood diseases in the study area. We generated a valuable inventory of medicinal plants and associated indigenous knowledge for child healthcare needs. However, investigating the biological efficacies, phytochemical profiles and the safety of these identified plants in relevant test systems remain essential in future research.

“…As revealed in the findings, most wild fruits were obtained from trees rather than shrubs. This finding aligns with [ 47 ] the ethnomedicinal survey conducted in the Urambo district of the Tabora region in central western Tanzania, where they reported that from wild fruits were obtained trees. The wild edible fruit species with higher utilisation frequency ( f ) and use reports (UR) were Vitex mombassae , Strychnos spinosa , Vitex payos , Phyllogeiton discolor , Vangueria infausta , Tamarindus indica , Parinari curatellifolia , Landolphia parvifolia and Microcos conocarpa (Cf.…”

“…Also, the respondents' sex constituted the female majority who headed their households different from males. In contrast [ 47 ] reported a similar custom in the North West Province where many households were female-headed. There was a significant association between respondents' sex and wild edible fruits knowledge.…”

Background Wild edible fruits found in Tanzania's miombo woods are an indispensable source of food and medicine. Unfortunately, with the rapid expansion of human activities and urbanisation in the Tabora rural, Uyui and Sikonge districts of Western Tanzania, some wild fruits are disappearing due to the loss of plant diversity. The objectives of this study wereL: to document the knowledge related to wild edible fruits; to quantify the use and cultural significance, and to determine their threats. Methods The ethnobotanical study was conducted from June 2022 to February 2023 involving 244 local informants. The study used field visits, the collection of plant parts, and semi-structured interviews with locals for its data collection. Descriptive statistics and correlation test were used to analyse the knowledge related to wild fruits. Frequency citation (f) and use reports (UR) were computed to understand the diversity and cultural significance (CI). Results The study documented 27 wild edible fruit species used for food and medicine. The life form constituted deciduous shrubs or trees (64%), shrub trees (21%) and evergreen or deciduous trees (15%). About (56%) of wild edible fruits were collected from June to August after the rainy season, (33%) were harvested between December and May during the rainy season, and (11%) were gathered from September and November before the rainy season. Household size and sex of the respondents were significantly correlated to the knowledge of wild edible fruits. Higher utilisation frequency (f) was recorded for Vitex mombassae Vatke (f = 0.84), Strychnos spinosa Lam. (f = 0.82), Vitex payos (Lour.) Merr. (f = 0.56), Phyllogeiton discolor (Klotzsch) Herzog. (f = 0.45), Vangueria infausta Burchell (f = 0.45), Tamarindus indica L. (f = 0.38), Parinari curatellifolia (f = 0.25), Landolphia parvifolia K.Schum. (f = 0.22) and Microcos conocarpa Burret (f = 0.22) fruits species. Additionally, Phyllogeiton discolor (Klotzsch) Herzog. (UR = 56), Vitex mombassae Vatke (UR = 56), Tamarindus indica L. (UR = 37), Strychnos spinosa Lam. (UR = 14) and Friesodielsia obovata (Benth.) Verdc. (UR = 11), have higher use reports (UR) and considered culturally important. Wild fruits were used to cure diabetes, gastrointestinal, reproductive, and respiratory infections ailments. Discussion and conclusion Multiple uses as well as the related knowledge of wild fruits have been documented. Friesodielsia obovata, Grewia flavescens Juss and Thespesia garckeana F.Hoffm. are the medicinal fruit species reported for the first time. Harvesting of wood plants, charcoal activities, crop cultivation, grazing expansion, and environmental change, have had an impact on the diversity of wild edible fruit plants. Over the past three decades, the use of wild fruits has been impacted by the loss of plant diversity due to decline of cultural norms on the forests management. Given the variety of uses for wild fruits, promoting markets for native fruits, sensitising the locals about the cultural importance and innovation on processing techniques are necessary to spur conservation efforts.

“…Studies on household expenditure and food consumption patterns have always been the focal point of research in developing as well as developed countries [62,63]. These go a long way to providing inputs into nutritional policy initiatives related to food, by updating food consumption patterns with changes in the commodity prices, disposable incomes and taxation.…”

The government’s lockdown and restriction measures on the COVID-19 pandemic adversely altered livelihoods, commodity/food prices as well as food security status in Nigeria, especially for rural farming households. A multistage sampling technique was used to collect data from 480 rural farming households across three selected states of the SouthWest geopolitical zone of Nigeria. This research entailed rapid evaluation of the determining factors of rising food expenditure, implications for food security as well as households’ coping strategies during the COVID-19 pandemic. A structured questionnaire was used to obtain data that were analyzed using the following descriptive and inferential statistics: double-logarithmic analysis, Foster–Greer–Thorbecke (FGT) and probit regression analysis. The results showed that 60% of respondents were married, mean years spent in school was 17, mean age was 49 years, household size was 7 people and monthly income less than $200. The FGT model results for head count ratio showed that 78% of households were food insecure. The depth of food insecurity and severity before COVID-19 were 18.4% and 9.9% respectively, and 27.1% and 13.0% during the pandemic. The double-logarithmic regression revealed that household income, size, age and occupation significantly influenced the household’s food expenditure. Probit regression showed that households’ income, size, amount spent on food, and the household’s head, gender and educational level influenced its food security status. The research concluded that food security was indeed influenced by the COVID-19 pandemic among rural farming households in Nigeria. Intervention policies are needed to promote and enable sustainable livelihoods to eradicate hunger and food insecurity due to high food prices and high household sizes in relation to their low average income to enable rural farming households to economically recover and have the capacity to sustain themselves against future shocks.
