Valuation of regulating ecosystem services in Africa: a review of policy impact reporting

(Integrated Environmental Assessment and Management, 2025-01-06) Gertrude, Akello; Godwin Opinde; Sammy Letema

Regulating ecosystem services (RES) play a very critical role in the sustenance of environmental health and human well-being, yet their valuation remains a complex and dynamic field. The variety of valuation methods, each with its strengths and limitations, as well as the limited methodological guidance for the selection of appropriate methods, poses a challenge in the valuation of RES. This review examined RES valuation studies in Africa, focusing on growth trends, methodological preferences, and policy reporting approaches. Drawing on the existing literature, we also explored the use of decision trees to support the choice of appropriate methods. A synthesis of peer-reviewed literature identified 31 studies, and their analysis revealed the dominant use of single-valuation methods in the assessment of RES and a varied growth rate in the number of valuation studies over the period under review. Furthermore, a notable heterogeneity exists in the methods used to report policy impact across various value assessments. This review contributes valuable insights into the current state of RES valuation research, necessary to advance methodologies, guide future research, and inform policy discussions on the sustainable management of ecosystems.

Teacher support and students’ academic resilience in universal secondary education schools in luwero district, Uganda

(Interdisciplinary Journal of Education, 2024-12-02) Justine, Nansamba; Wilson Mugizi; Joseph Rwothumio; Joshua Kimata Kato

This study investigated the impact of teacher support on students' academic resilience in Universal Secondary Education schools in Luwero district, Uganda. Specifically, the study examined whether teacher investment of effort, positive regard, and accessibility significantly influenced students' academic resilience, defined as perseverance, help-seeking, and positive affect. Using a quantitative approach and correlational research design, the study surveyed 324 students selected through simple random sampling. Data collection employed a self-administered questionnaire, and analysis involved structural equation modelling (SEM) using SmartPLS. The results revealed that teacher investment of effort, positive regard, and accessibility had a positive and statistically significant impact on students' academic resilience. The findings suggest that teacher support, particularly positive regard, followed by investment of effort and accessibility, fosters students' academic resilience. The study recommends that head teachers sensitise teachers to provide comprehensive support by creating a supportive learning environment that involves being invested in students' academics, accessible, and showing positive regard. This study's practical contribution lies in demonstrating how teacher support can promote students' resilience, providing valuable insights for educators and policymakers.

The effect of structured coaching on lecturers’ feedback skill development in national teachers’ colleges in Uganda

(East African Journal of Education Studies, 2025-01-06) Sarah, Nawoova; Stephen Ndawula; Mark Waiswa

This study investigated the effect of coaching on the feedback skills of lecturers in National Teachers’ Colleges in Uganda, drawing on the theories of Cognitive Apprenticeship and Vygotsky’s Sociocultural Theory, which emphasize learning through guided experience and social interaction. The study was guided by a postpositivist world view and it employed a mixed-methods embedded approach, the research utilized a pretest-posttest control group design to assess whether there was a significant difference in the feedback skill of lecturers who received coaching compared to those who did not receive coaching. A sample of 128 lecturers was purposively selected, stratified, and randomly assigned to experimental and control groups. The experimental group received structured coaching sessions, while the control group did not. Quantitative data was collected using a self-administered questionnaire and an observation checklist while structured interview guides provided the qualitative data. The quantitative data were analyzed using descriptive statistics and inferential statistics through a t-test, while qualitative data were examined through content analysis. The post-test results revealed that the experimental group performed better, with a mean difference of 0.38078 points and a p-value of 0.000 < 0.05 which is statistically significant. Participants from the experimental group in the interviews reported a positive contribution of coaching to their learning and skill proficiency. The hypothesis that there is no significant difference in the feedback skill of lecturers who received coaching compared to those who did not receive coaching was therefore rejected. It was concluded that coaching is significant for improving lecturers’ feedback skills. It was therefore recommended that institutions should consider integrating coaching as a CPD for lecturers’ capacity building in performance. Institutions should also design tailormade coaching strategies to address individual gaps of lecturers and create communities of practice to establish a supportive network for more learning

Admission of non-traditional students in the 21st entury universities: a tradition of transformations

(East African Journal of Education Studies, 2025-01) Jordan, Byekwaso Lwanga; Willy Ngaka; George Ladaah Openjuru

This article analyzes the transformations in the organization and governance of admissions for older adults (non-traditional students – NTSs) in higher education at one of the public universities in Uganda. Adulthood demands acquiring new coping strategies and skills to adapt to the requirements of new and emerging roles. This demand goes beyond depending on introductory training and informal experiences based on cultural wisdom. A growing belief underscores HE as a critical tool in responding to these demands. To champion this belief, many universities are contextually defining and implementing admission decisions to select deserving adults to enrol for university education. We collected qualitative data from university managers (some of whom doubled as academics), mature age coaches, and graduate and continuing non-traditional students. The purpose of this article was to analyze how institutional decisions on the admission of non-traditional students have evolved and their implications on the future development of the HE sector. This article illustrates and concludes by raising awareness among current and future sector managers and scholars who might be new to NTSs on how institutional decisions leading to their enrolment emerged and their implications for future practice.

Ethnobotany, total polyphenol content, and cytotoxicity of African olive (Canarium schweinfurthii Engl.) Fruit Pulp

(Discover Food, 2024-12-24) Arthur, Tabula; Khadijah Nakyinsige; Michael Bamuwamye; Praise Komujuni; Otmar Hoeglinger

In Uganda, indigenous knowledge, total polyphenol content and cytotoxicity of Canarium schweinfurthii Engl. have not been documented, which may limit its utilization. Henceforth, this study aimed at conducting an ethnobotanical survey and determining total phenolic content, antioxidant capacity and cytotoxicity of C. schweinfurthii fruit pulp. The ethnobotanical survey was conducted in Kamuli, Luwero, and Mayuge districts, Uganda using validated questionnaires following purposive and snowball sampling. Following cold and hot water extraction of the fruit pulp extract, Total Polyphenol Content (TPC) was determined using the Folin-Ciocalteu method while the antioxidant capacity on human colon (Caco-2) cell lines was determined using the oxidative stress and 2′,7′-dichlorodihydrofuorescein diacetate staining model. Cytotoxicity at 1:2, 1:5, 1:10, 1:25, 1:50, 1:100, 1:200 and 1:1000 concentrations was determined using the human colon (Caco-2) cell lines and resazurin assay. The study revealed that various parts of C. schweinfurthii are used in the management of various health complications whereas the fruit is utilized as food. The TPC obtained for C.schweinfurthii fruit pulp was 2.48 ± 0.10 and 2.88 ± 0.02 mg GAE/g dry weight for cold and hot extracts, respectively. There was no signifcant antioxidant activity observed after treatment of human colon (Caco-2) cell lines with the diferent fruit pulp extract concentrations. Zero to very low cytotoxicity was observed in cell lines treated with 1:10, 1:25, 1:50, 1:100, 1:200 and 1:1000 fruit pulp extract. The fndings of this study suggest that in addition to its utilization as a food, C.schweinfurthii fruit pulp is a potential therapeutic agent.
