Book Description
Moringa oleifera Lam. can survive extreme growth conditions by adjusting its metabolism. Among the potential metabolites produced during adaptation are glucosinolates, which possess potential cancer chemoprotective attributes. Recent climate events, such as increased temperatures and prolonged drought, impact crop yield and quality significantly. Therefore, climate-resilient plants such as M. oleifera can be utilized in areas where crop production is adversely affected. Understanding how terroir factors and cultural practices affect the glucosinolate profile in M. oleifera is important for optimizing cultivation strategies. To achieve this, the leaves from cultivated and wild-grown mature M. oleifera plants were harvested for intact glucosinolates analysis. Prior to the analysis, preserving the plant materials to prevent the breakdown of glucosinolates was important. Given that the use of dehydration methods such as freeze drying for the leaves is expensive and laborious in developing countries like Ghana, a locally well-suited dehydration method, namely oven-drying at 40 °C for 48 h, was identified and utilized. Results showed that during the rainy season, climate parameters did not significantly influence the total glucosinolates content in all leaf materials harvested. In contrast, accession selection, harvest time, and agro-ecological zones significantly influenced the total glucosinolate content. Fertilization significantly altered the vegetative growth parameters of the cultivated accessions, but not the total glucosinolates content. In conclusion, M. oleifera proved to be well adapted to the climate in Ghana. The continued collection, storage, and use of the genetic resources of M. oleifera accessions well-adapted to stress conditions are envisaged to ensure the species‘ contribution towards improved food security and nutrition among vulnerable groups.

Book Description
Inadequate pre- and postharvest treatments of agricultural produce are one of the central problems developing countries are facing resulting in low yield and poor quality African indegenous leafy vegetables (AIVs). AIVs are rich in nutritional and health promoting plant compounds such as vitamins, minerals, proteins, dietary fibre and antioxidant compounds. However, due to high perishability and low storage capacity in fresh form, AIVs suffer significant loss in quantity and quality. Aim of the present study was to assess the situation of postharvest losses during AIVs supply chain (from smallholder farmer to consumer), determine the amount of postharvest loss (quantitave and nutritional) along the supply chain in Kenya. Thereafter, a series of studies were conducted on pre-harvest (electric current) and postharvest (UV-C irradiation) treatments to determine their effects on primary compounds (chlorophylls, mineral elements, proteins and dietary fibre) and secondary metabolites (carotenoids, flavonoids, phenolic acids, phenolic compounds, glutathione peroxidase (GPOX), and vitamin E) and microbial status as well as antioxidant capacity, in order to strengthen a product quality and safety oriented food supply chain. The study focussed mainly on two commonly consumed AIVs i.e. Vegetable amaranth (Amaranthus cruentus L. cv. Madiira) and African nightshade (Solanum scabrum Mill. cv. Olevolosi).

Book Description
Classification, as an object of recent anthropological scrutiny came to prominence during the 1960s, exemplified in the British (constructionist) tradition by the writings of Mary Douglas, and in the American ethno-semantics (cognitive) tradition by the likes of Harold Conklin and Brent Berlin. At the time, these approaches seemed by turns to contradict each other, or even to exist in parallel universes. However, over the last 30 years we have witnessed both a renewed interest in classification studies as well as a cross-fertilization of these once antagonistic approaches. These essays by one of leading scholars in this field bring together a body of influential and inter-linked work which attempts to bridge the divide between cultural and cognitive studies of classification, and which develops a more embedded and processual approach. In particular, the essays focus on people's categorization of natural kinds as a means through which to obtain an understanding of how classifying behavior in general works, engaging with the ideas of both anthropologists and psychologists. The theoretical background is set out in an entirely new and substantial introduction, which also provides a comprehensive and systematic review of developments in cognitive and social anthropology since 1960 as these have impacted on classification studies. In short, it constitutes a useful and approachable introduction to its subject.

Book Description
This book highlights the results from over a year of ethnobotanical research in a rural and an urban community in Jamaica, where we interviewed more than 100 people who use medicinal plants for healthcare. The goal of this research was to better understand patterns of medicinal plant knowledge, and to find out which plants are used in consensus by local people for a variety of illnesses. For this book, we selected 25 popular medicinal plant species mentioned during fieldwork. Through individual interviews, we were able to rank plants according to their frequency of mention, and categorized the medicinal uses for each species as “major” (mentioned by more than 20% of people in a community) or “minor” (mentioned by more than 5%, but less than 20% of people). Botanical identification of plant specimens collected in the wild allowed for cross-linking of common and scientific plant names. To supplement field research, we undertook a comprehensive search and review of the ethnobotanical and biomedical literature. Our book summarizes all this information in detail under specific sub-headings.
