“…Uprety et al (2012) argued that documentation and conservation of wild edible plants are important as this would ensure that the highest priority genetic diversity is preserved and made available for use in crop improvement programs as a contribution to future worldwide food security. Moreover, documenting such information on utilization of plant species based on perceptions of local communities is an important step in trying to understand and initiate a management protocol that incorporates public perceptions and values associated with utilization of plant resources (Atyosi et al, 2019). In conclusion, results of this study have added invaluable information on edible vegetable species in the Eastern Cape Province in South Africa.…”

Abstract. Maroyi A. 2020. Short Communication: Ethnobotanical study of wild and cultivated vegetables in the Eastern Cape Province, South Africa. Biodiversitas 21: 3982-3988. Vegetables are an important component of agricultural biodiversity required for providing a wide range of ecosystem goods and services. The current study was undertaken in the Eastern Cape Province, South Africa to document wild and cultivated vegetables. Research data were collected by means of interviews and field surveys carried out in different seasons with one hundred and thirty-eight randomly selected participants. During the interviews, we documented information on names of edible vegetables, uses, plant parts consumed, and their preparation. A total of 32 species belonging to 26 genera and 15 families were recorded in the study area. The plant families with highest number of vegetable species were Amaranthaceae, Asteraceae, and Solanaceae with at least four species each. The main uses of vegetables identified in the study area were leafy vegetables (59.4%), edible fruits and tubers (21.9% each), culinary herbs or spices (12.5%), edible seeds (9.4%) and edible stems (6.3%). The species which were categorized as important with relative frequency of citation (RFC) values >0.3 were Brassica oleracea, Solanum tuberosum, Cucurbita moschata, Spinacia oleracea, and Cucurbita maxima. Both vegetable species collected from the wild and conventional vegetables cultivated in home gardens are important to livelihoods needs of the local people.

“…Some IAPs are utilised as traditional leafy vegetables owing to their nutritional value, thus making a significant contribution to human well-being [122][123][124]. In southern parts of Nigeria, C. odorata leaves are consumed as a vegetable, and this is largely attributed to high nutritional content in the leaves [41].…”

Invasive alien plants (IAPs) have been well-documented as socio-ecological change drivers in most countries globally. Billions of dollars have been spent worldwide on IAP management projects with varying degrees of success. Understanding the contribution of IAPs to human well-being and livelihoods could provide insights into potential sustainable incentives that could be used to achieve effective IAP management. A review was conducted to assess the benefits of the invasive Chromolaena odorata on human well-being and livelihoods. Literature was gathered using keyword searches in electronic databases. The findings from this review showed that C. odorata is utilised in bioenergy production, crop production and protection, ethnopharmacology, human nutrition, and livestock production. However, most of these benefits were reported on the Asian/West African biotype. There was only one ethnopharmacological benefit record on the southern African biotype. This shows that, although C. odorata has significant negative impacts on the environment and livelihoods, its benefits have been integrated into human well-being and livelihoods. Therefore, C. odorata utilisation in bioenergy production, crop and livestock production, crop protection, and ethnopharmacology could create an economic incentive for species control in invaded sites. However, for utilisation to be effective, it should be used as a complementary control strategy.

“…The research showed that the main invasive plants in Zhejiang Province were herbs, which grow fast and have strong reproductive capacity [24]. Alien species were often considered to have a negative impact on local biodiversity, but research showed that interaction with alien species was neutral or even promoted native species [25], and alien species were even more dynamic and competitive than native species [26]. Alien plants had not reduced the diversity of native species and had a great contribution to the richness of herbs.…”

The construction of the ecological environment in rural settlements is a very important part of the development of human settlements. Key to this construction is the coordinated and sustainable development of plant environment, geographical environment, and human activities. Therefore, it is necessary to study the characteristics of plant diversity and their driving mechanisms. The study area, ‘Shanchuan Town’, is located in the hilly area of Southeast China, Anji County, Zhejiang Province. As bamboo forests cover 62% of the total forests, it has the reputation of being the “China town of bamboo”. To interpret rural plant community features, we extracted topography data by the field survey, satellite image, and Digital Elevation Model (DEM) based on ArcGIS platform, then used Spearman’s correlation and a redundancy analysis to examine the relationships between explanatory variables (e.g., plot elevation, slope aspect and architectural height, etc.) and the distribution of plant community diversity. In this study, 227 plots were selected from 14 settlements to investigate totally 105, 88, 206, and 17 species of trees, shrubs, herbs, and vines, respectively, belonging to 147 families, 324 genera, and 416 species. Among them, there were 19 bamboo species, and 47 species of alien plants, which accounted for 11.3% of the total. The dominant trees and shrubs were mainly native species with high edible or ornamental value. The dominant bamboo species were common species for bamboo shoots in Zhejiang Province, while most of the dominant herbaceous species were alien species. Among the explanatory variables, the impact of plot elevation (PE) on plant community was significantly higher than those of other explanatory factors. The correlation analysis showed that the richness and diversity indices of different plant life layers were significantly related to PE. Among the architectural factors, the architectural orientation (AO) and layout type (AT) effect on shrubs and other herbaceous species was stronger than those on trees and bamboo. There was a high plant community richness in the study area, and both topography and architectural factors had a significant effect on plant community. Therefore, construction of the plant landscape should conform to the topography and regulate the residential construction activities properly, so as to get rid of urban planning thinking and the excessive pursuit of plant diversity, realizing the sustainable development of ecological environment in settlements.
