Dans la droite ligne de l’assertion, qui veut que « ton aliment soit ton remède », la présente étude vise à déterminer les modalités de consommation, les usages alimentaires et thérapeutiques de quelques espèces locales. Ainsi une enquête a été menée avec un échantillonnage par commodité auprès de 200 participants à savoir les tradipraticiens, les revendeurs, les transformateurs, les personnes âgées et des femmes en âge de procréer. L’étude a permis d’identifier une grande diversité d’organes utilisés dans l’alimentation humaine et thérapeutique. Les fruits entiers, les pulpes et les graines sont les plus utilisés respectivement à 46,30% ,38,02% et 85,99%. La poudre, avec 45,80%, était le principal mode de préparation. Les principaux modes de consommation sont la sauce (19,25%), la bouillie (17,60%), la tisane (13,43%), le jus (12,13%), le lait (3,12%) et autres recettes (35,74%). Les raisons d’utilisation moyennes des espèces étaient le manque d’appétit (3,47%), la prise de poids (14,28%), aliment (76,11%), le complément alimentaire (10,00%), pour avoir la force (6,64%) et le sang (6,67%). Il faut noter que (72,68%) des participants ne connaissent pas les usages médicinaux de ces plantes. Les utilisations pour le traitement de maladies concernent : Adansonia digitata (11,04%) et Parkia biglobosa (25%) pour traiter la diarrhée ; Adansonia digitata (49,41%), Ziziphus mauritiana (13,51%), Pennisetum glaucum (16,17%) et le Sclerocarya birrea (17,94%) pour le traitement de l’hémorroïde. Quant à Vigna unguiculata, elle est utilisée contre l’inflammation à 14,56% et le Ziziphus mauritiana pour le traitement de la fièvre (4,50%). Ces résultats confirment que les espèces peuvent être utilisées dans la prise en charge de la malnutrition et de certaines maladies.

In line with the assertion that “your food is your medicine”, this study aims to determine the consumption methods, food and therapeutic uses of some local species. Thus, a survey was conducted with convenience sampling among 200 participants, namely traditional practitioners, resellers, processors, elderly people and women of childbearing age. The study made it possible to identify a wide diversity of organs used in human food and therapeutics. Whole fruits, pulps and seeds are the most used at 46.30%, 38.02% and 85.99% respectively. Powder, with 45.80%, was the main method of preparation. The main modes of consumption are sauce (19.25%), porridge (17.60%), herbal tea (13.43%), juice (12.13%), milk (3.12%) and other revenues (35.74%). The average reasons for species use were lack of appetite (3.47%), weight gain (14.28%), food (76.11%), food supplement (10.00%), strength (6.64%) and blood (6.67%). It should be noted that (72.68%) of participants do not know the medicinal uses of these plants. Uses for the treatment of diseases include Adansonia digitata (11.04%) and Parkia biglobosa (25%) to treat diarrhea; Adansonia digitata (49.41%), Ziziphus mauritiana (13.51%), Pennisetum glaucum (16.17%) and Sclerocarya birrea (17.94%) for the treatment of hemorrhoids. As for Vigna unguiculata, it is used against inflammation at 14.56% and Ziziphus mauritiana for the treatment of fever (4.50%). These results confirm that species can be used in the treatment of malnutrition and certain diseases.

Case Study: An Evaluation of an ESP Textbook Used at the College of Business Studies in Kuwait from the Learners' Perspective Regarding Its Alignment with Future Career Requirements

A key aspect of learning English is evaluating the materials. It is regarded as a cornerstone in the field of English for Specific Purposes. The purpose of this study is to evaluate an ESP textbook that is taught at Kuwait's College of Business Studies. It looks at how learners perceive the textbook. The study also aims to determine whether the textbook helps in preparing learners for their future business careers. A series of research instruments, including a questionnaire, a checklist, and interviews, were developed for this purpose. The results proved that the learners' opinions of the textbook varied. While a minority of students felt that the textbook was unsuitable for their level of English proficiency, the majority of students liked it and thought it was useful and met their requirements. The results also proved that the textbook prepared the learners for their future careers to a certain degree.

Assessment of Carbon Sequestration Potentials and environmental dynamics in the coastal area of Lagos

Coastal environments comprise of multiple arrays of ecosystems, including forests, mangroves, wetlands, and oceans, which play a vital role in long-term carbon storage and mitigation of climate change. These ecosystems possess a unique ability to store carbon for prolonged periods, acting as natural carbon sinks and contributing to the reduction of atmospheric greenhouse gas up concentrations, which is one of the exceptional services they offer. However, despite their significance, the potentials of coastal land covers and their associated land use in mitigating global warming through carbon absorption is often overlooked in current researches. This study employed the InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) model together with Intergovernmental Panel on Climate Change (IPCC) Carbon pool data to assess the carbon stock and dynamics of various land use and land cover types in the coastal environment of Lagos for a period of 20 years. The results revealed a substantial reduction in net stored carbon from 1.33 x 10⁸ metric tons Carbon in 2003 to 1.21 x 10⁸ metric tons of Carbon in 2013, which accounts for a 6.66% decline in stored carbon during that period. Furthermore, the total carbon stock decreased by approximately 3.5 x10⁸ Metric tons, or 2.94%, equating to a loss of over 300 million tons of carbon between 2013 and 2023. Through the identification and measurement of the carbon sequestration capacity of these varied coastal land covers, researchers can gain insight regarding their function in reducing global warming. The preservation and enhancement of these natural carbon sinks can be achieved by conservation efforts, sustainable management practices, and policy decisions informed by this information, thereby aiding in the global fight against climate change.
