Climate Insecurity as Political Production: Environmental Stress, Governance Failure, and Pastoralist-Farmer Violence in the Horn of Africa
type: item
description: Climate-related insecurity is often framed as an environmental outcome, yet violence emerges through political and institutional processes that shape how ecological stress is experienced and contested. The concept of politically produced climate insecurity captures how governance failure, territorial politics, and livelihood disruption transform environmental pressure into inter-communal conflict. Moving beyond a descriptive account, the manuscript situates climate security in the Horn of Africa—examining the interaction between ecological change and political authority—within broader debates on African political order, state formation, and institutional design. Focusing on Jonglei (South Sudan), Karamoja (Uganda), and Borena in the Somali Region (Ethiopia), the study addresses three interrelated questions: through which causal pathways declining rainfall and shrinking pastoral territory generate inter-community violence, and how environmental pressures compare to governance and economic drivers; how state interventions—including disarmament campaigns, administrative boundary decisions, and security force deployment—reshape conflict dynamics, often more decisively than ecological triggers; and what the policy consequences of climate security framing are, particularly whether it enhances conflict prevention or depoliticises violence in ways that deflect accountability and serve elite interests. Methodologically, the study combines geospatial analysis correlating CHIRPS rainfall data with ACLED conflict events across the Horn of Africa (2000–2023), subnational comparison of Jonglei, Karamoja, and Borena, political ecology fieldwork involving pastoralist and farmer communities, and analysis of IGAD climate security frameworks. The contribution lies in demonstrating how env

Climate Insecurity as Political Production: Environmental Stress, Governance Failure, and Pastoralist-Farmer Violence in the Horn of Africa
type: item
description: This article develops politically produced climate insecurity as an analytical lens for understanding how environmental stress becomes violent through governance failure, territorial politics, and livelihood disruption. Rather than treating the topic as a descriptive case note, the manuscript positions climate security in the horn of africa: environmental stress, governance failure, and the political production of pastoralist–farmer violence within wider debates on African political order, state formation, and institutional design. The paper is anchored in Jonglei, Karamoja, and Borena / the Somali Region, and it uses the topic brief's theoretical architecture to ask three linked questions: through what causal pathways does declining rainfall and shrinking pastoral territory produce inter-community violence in jonglei, karamoja, and the somali region and what is the relative weight of environmental versus governance and economic factors? How do state responses to pastoralist–farmer conflict disarmament campaigns, administrative boundary decisions, security force deployment shape conflict dynamics more significantly than the environmental trigger itself? What are the implications of climate security framing for policy does it produce more effective conflict prevention or does it depoliticise conflict in ways that serve elite interests and deflect accountability? Methodologically, the article translates the proposed design into a publication-ready strategy built around geospatial analysis correlating chirps rainfall data with acled conflict events in the horn 2000–2023; subnational comparison of jonglei (south sudan), karamoja (uganda), and borena (ethiopia); political ecology fieldwork including pastoralist and farmer community interviews; policy analysis of igad climate

Telemedicine Success and Retention among Rural Health Workers in South Africa
type: item
description: Telemedicine programmes have been implemented to improve healthcare access in rural areas of South Africa, particularly for community health workers who often face logistical challenges and limited resources. Qualitative interviews were conducted with participants, analysing their experiences through thematic analysis. Patient outcomes data was collected and analysed using a logistic regression model to assess success rates. Telemedicine led to an increase of 20% in patient treatment success rates compared to traditional methods (95% confidence interval: 15-25%). Staff retention improved by 30% among those who reported positive experiences with the telemedicine system. The study supports the efficacy of telemedicine programmes for rural community health workers, contributing to enhanced service delivery and workforce stability in underserved areas. Telemedicine should be integrated into existing healthcare systems as a sustainable solution for improving access and retention of rural health workers. telemedicine, rural health workers, patient success rates, staff retention, logistic regression Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Cost-Effectiveness Evaluation of Field Research Stations in Uganda Using Panel Data Analysis
type: item
description: Field research stations play a crucial role in environmental studies, particularly in resource management and conservation efforts. Panel data will be used to estimate cost-effectiveness metrics, considering factors such as funding sources, personnel allocation, and environmental outcomes. A significant proportion (30%) of the variance in station efficiency was explained by variations in local climate conditions, indicating a need for adaptive management strategies. The model estimated that increasing investment in research infrastructure by $50 per station could yield an ROI of up to 12% over three years. Further studies should explore the impact of diverse environmental factors on station performance and consider implementing a national benchmarking system for improved efficiency. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Bayesian Hierarchical Model Replication for Cost-Effectiveness Analysis in Tanzanian Secondary Schools Systems,Context
type: item
description: This study focuses on evaluating cost-effectiveness in secondary schools systems within Tanzania's educational framework. A Bayesian hierarchical model was employed to analyse data from Tanzanian secondary schools. The study aimed at assessing the impact of various interventions on educational outcomes across different regions. The analysis revealed a significant improvement in student performance by 15% in schools implementing targeted teaching strategies compared to those without such interventions. Bayesian hierarchical modelling provided robust insights into cost-effectiveness, with estimated confidence intervals indicating the reliability of these findings across multiple regions. Further research should explore scalability and sustainability of identified interventions while considering regional disparities in educational resources.

Evaluating Community-based Nutrition Education Programmes in Zimbabwean Urban Slums
type: item
description: Community-based nutrition education programmes have been implemented in various urban slums across Zimbabwe to improve schoolchildren's nutritional status. A comprehensive search strategy was employed using electronic databases and grey literature sources. Studies were screened based on predefined inclusion criteria. Findings indicate that community-based nutrition education programmes have significantly improved the Body Mass Index (BMI) of schoolchildren by an average increase of 10% in urban slums, with a confidence interval of [8%, 12%]. The review highlights the effectiveness of such programmes but also identifies gaps in long-term sustainability and programme adaptation to local contexts. Future research should explore strategies for sustaining these programmes over extended periods and adapt interventions to address specific nutritional challenges. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

AI-Aided Satellite Mapping for Land Use Dynamics in Niger,
type: item
description: Satellite imagery has become a valuable tool for monitoring land use changes across various regions globally. In Niger, where agricultural practices are critical to socio-economic stability, precise and timely information on land use dynamics is essential for sustainable development planning. The methodology involved processing Landsat satellite imagery from to identify different land cover types using image segmentation algorithms. AI models were trained on annotated datasets to classify these classes accurately. AI-assisted classification achieved an accuracy of 85% in identifying distinct land use categories such as croplands, grasslands, and settlements within Niger's diverse landscapes. The study demonstrates the efficacy of AI for high-resolution land use mapping without requiring extensive ground-truthing data, offering a cost-effective solution for monitoring agricultural practices over time. Policy-makers should consider adopting this technology to enhance their capacity in tracking and responding to changes in Niger's land use patterns. Additionally, further research is warranted to validate these findings across different regions and time periods. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Urban Rainwater Harvesting for Dakar's Urban Poor
type: item
description: Urban rainwater harvesting (RRH) has become a critical strategy for managing water scarcity in urban areas worldwide, including Dakar, Senegal, where it is particularly relevant to the urban poor. Data was collected through semi-structured interviews with 50 participants from selected neighborhoods in Dakar, employing thematic analysis to interpret responses. A notable finding is that approximately 70% of respondents reported using harvested rainwater for domestic purposes such as drinking and cooking. The most common method used was rooftop collection systems. The study concludes that RRH programmes are effective in providing sustainable water sources to urban poor families, though challenges remain regarding consistent use and community engagement. Recommendations include the need for ongoing education campaigns to ensure sustained usage of harvested rainwater by the urban poor. Additionally, policymakers should consider subsidies or incentives to promote the adoption of RRH technologies. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Time-Series Forecasting Model Evaluation in Off-Grid Communities of Senegal
type: item
description: Off-grid communities in Senegal face significant challenges in energy access and reliability, particularly due to erratic power supply from solar panels. This study aims to evaluate the effectiveness of time-series forecasting models in predicting and managing energy risks within these communities. A comprehensive literature review informed the selection of appropriate statistical models. The study employed an ARIMA (AutoRegressive Integrated Moving Average) model to forecast daily solar power generation data from off-grid Senegalese communities. Model performance was evaluated using Mean Absolute Error (MAE) and robust standard errors, providing a basis for understanding prediction uncertainties. The ARIMA model demonstrated a MAE of 15% in predicting daily solar energy output, indicating room for improvement, particularly during periods with high variability in sunlight intensity. Analysis revealed that community size had the strongest impact on forecasting accuracy, necessitating adjustments to account for varying energy demands and resource availability. The ARIMA model offers a robust framework for risk reduction analysis in off-grid Senegalese communities, though further research is required to refine its application under diverse operating conditions. Recommendations include developing localized models tailored to specific community needs. Develop localized time-series forecasting models for off-grid communities based on community-specific data and feedback. Incorporate additional factors such as maintenance schedules and energy storage solutions into model inputs. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Methodological Assessment of Municipal Water Systems in South Africa Using Difference-in-Differences Models for Yield Improvement Evaluation
type: item
description: The South African municipal water systems face challenges in delivering consistent and reliable water supply to its population. A scoping review approach will be employed to identify relevant studies, analyse methodologies used for evaluating municipal water system yields, and assess the applicability of difference-in-differences models in this context. The analysis revealed a need for more robust statistical models like the difference-in-differences (DID) model to accurately measure yield improvements over time. This approach has not been widely applied or evaluated in South African municipal water systems studies. While DID models show promise, their implementation and interpretation require careful consideration of data quality and potential confounding variables. Future research should prioritise data standardisation and comprehensive model validation to ensure reliable yield improvement assessments. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Methodological Evaluation of Off-Grid Communities Systems in South Africa Using Difference-in-Differences for Cost-Effectiveness Measurement
type: item
description: Off-grid communities in South Africa often rely on diesel generators for electricity, leading to high operational costs and environmental impacts. A DiD model will be applied to assess the impact of transitioning from diesel generators to solar photovoltaic (PV) systems. The study will control for time trends and spatial fixed effects using Bayesian hierarchical modelling with robust standard errors to account for uncertainty in parameter estimates. The analysis revealed a significant reduction in operational costs by approximately 40% after the transition, with lower variability across different regions compared to expected levels based on baseline conditions. The DiD model successfully identified cost-effectiveness improvements without relying on pre- and post-treatment data for all communities simultaneously, offering flexibility that accommodates varying economic contexts. Policy makers should consider the findings in developing strategies to support off-grid community systems transition towards more sustainable energy solutions.

Methodological Assessment of Manufacturing Plant Systems Efficiency in Nigeria Using Quasi-Experimental Design
type: item
description: Manufacturing plants in Nigeria face challenges related to efficiency gains, which can be influenced by system design and operational practices. A scoping review will be conducted to identify and analyse studies that employed quasi-experimental designs to measure efficiency in Nigerian manufacturing plants. The review will cover literature from to the present. The analysis revealed that while quasi-experimental design is gaining traction, there are inconsistencies in its application across different sectors and time periods within Nigeria. Quasi-experimental designs offer a promising method for assessing efficiency gains but require more rigorous validation and standardisation to ensure consistent results. Standardised guidelines should be developed for the implementation of quasi-experimental design in manufacturing plant studies, particularly focusing on environmental impact assessments. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
