“…The contribution of herbs and shrubs to the species richness recorded in home gardens is a reflection of the life form of most Ghanaian staple foods which are sourced from herbs and shrubs [ 41 ]. The most important species identified in the home gardens of the Sunyani municipality are all used in households regularly for both nutritious and culturally important diets.…”

Background Home gardens are a species-rich socioecological system with a diverse range of cultivated and naturally occurring plants with the potential to make contributions to address sustainable food, biodiversity and climate crisis. However, there is a dearth of information on the socio-demographic profile of home gardeners and the importance of home gardens to ethnobotany, food security and biodiversity. Therefore, the study aimed to assess the socio-demographic profile of home gardeners in the Sunyani municipality as a case in point for the middle belt of Ghana and to evaluate the diversity of plants in home gardens and their ethnobotanical importance. Methods A total of 12 suburbs were selected from three subzones in the Sunyani municipality. In each suburb, 25% of households were randomly selected and if they had a home garden, one adult in the house was interviewed. A list of all plants in the home garden and their uses was obtained from respondents. A Chi-square test was used to assess the distribution of home gardeners among various socio-demographic categories, and binomial logistic regression was employed to determine links between socio-demography and home garden attributes. The ethnobotany R package was used to evaluate the ethnobotanical importance of plants in home gardens. Results A total of 186 respondents were recruited for this study, 79 being females and 107 males. A total of 79 plant species were also identified belonging to 70 genera and 40 families. Trees were the most common plant life form in home gardens, followed by shrubs, herbs, vines, grasses and lianas. Ethnobotanical indices revealed the most important plants in home gardens to be staples, food supplements and medicinal plants. These were Musa paradisiaca, Caripa pabaya, Xanthosoma sagittifolium, Manihot utilisima and Mangifera indica, Moringa oleifera, Citrus sinensis, Capsicum frutescens, Taraxacum officinale, Solanum aethiopicum, Cocos nucifera, Solanum torvum, Persea americana, Dioscorea alata and Elaeis guineensis. Conclusion Plants used as staples, food supplements and medicinal purposes emerged as the most culturally relevant scoring high on all ethnobotanical indices. Home gardens present an opportunity to address food security and nutrition needs of households and communities.

“…Subsistence agriculture remains the main source of livelihood for the majority of the northern region’s inhabitants, with a significant proportion involved in trading and relatively few highly educated and skilled professionals. October to December usually is the peak of the harvesting season, during which there is usually an abundance of indigenous staple foods, such as maize, sorghum, millet, and yams, except when occasional natural disasters derail the season’s harvest [ 41 , 42 ].…”

Composite child feeding indices (CCFIs) developed from various relevant measures of dietary intake by infants and young children have several potential applications in nutritional epidemiological studies for the development and deployment of precise public health nutrition interventions against child undernutrition. The predictive utility of some CCFIs (computed from varying formulation components) for child nutritional status (stunting, wasting, and underweight) were compared. The purpose of the study was to identify the most suitable among them for possible standardization, validation, and adoption by nutritional health researchers. Using cluster sampling, data from 581 mother–child pairs were collected. Multivariable regression analyses were applied to the data obtained through a community-based analytical cross-sectional survey design. Three of the CCFIs were found to be significantly associated with only wasting (WHZ) from the linear regression models after adjusting for potential confounders and/or correlates. None of the CCFIs (whether in the continuous nor categorical form) was consistently predictive of all three measures of child nutritional status, after controlling for potential confounders and/or correlates, irrespective of the choice of regression method. CCFI 5 was constructed using a dimension reduction technique—namely principal component analysis (PCA)—as the most optimal summary index in terms of predictiveness for child wasting status, validity, and reliability (Cronbach’s α = 0.80) that captured relevant dimensions of optimal child food intake. The dimension reduction approach that was used in constructing CCFI 5 is recommended for standardization, validation, and possible adoption for wider applicability across heterogeneous population settings as an optimum CCFI usable for nutritional epidemiological studies among children under five years.

“…Hence, the study objectives were to (1) screen and select drought-tolerant cultivars among the rice germplasms collected and (2) to estimate their heritability of yield parameters including spikelet fertility, fertile panicle rate, spikelet length, number of grains, root dry weight, grain weight, dry root weight, maximum root length, total root length, panicle length, effective tillers, leaf rolling, and leaf drying.…”

About 70% of the rice consumed in Ghana is imported. The state of self-insufficiency in rice production can be attributed to the lack of adequate or continuous water supply. Rice, being an aquatic plant, is not tolerant to drought, which is known as the most threatening abiotic factor causing as much as 64% yield reduction. Therefore, this study was conducted to identify drought-tolerance genotypes among 24 rice collections and to estimate their heritability. A total of 24 traits were assessed in this study, and three treatments were applied, including stress free, mild stress, and severe stress, each of which involved three replications. The results showed that most of the parameters under investigation, including panicle length, fertile panicle rate, shoot, and root dry weight, and maximum root depth, decreased considerably as the level of drought stress increased. In addition, five of the accessions showed considerable tolerance to drought, eight accessions were high yielding, and eight accessions combined high yields and drought tolerance. The study concluded that 80% of the rice accessions offer promising lines to be used as parents in the development of drought-tolerant varieties and in genetic improvement programs aimed at such a purpose. The study recommended that molecular studies and morphological characterization should be done on the collections to understand their genetic makeup, similarities, and differences.
