Climate-Resilient Infrastructure Design for Flood Management in Mozambique
type: item
description: Floods in Mozambique pose significant threats to infrastructure and human settlements, necessitating resilient design strategies that can mitigate climate-related risks. A mixed-methods approach combining field surveys, remote sensing analysis, and expert interviews was employed to assess current flood risk levels and identify potential design solutions. A probabilistic model predicting future flood scenarios under climate change conditions informed the design parameters. An analysis of historical rainfall patterns revealed a clear trend towards increased intensity and frequency of floods over the past decade, necessitating proactive adaptation measures. The study concludes that incorporating adaptive infrastructure designs into existing structures can significantly enhance their resilience to climate-induced flood events in Mozambique. Local authorities are recommended to implement the proposed design guidelines for future construction projects and integrate these strategies as part of ongoing flood risk management efforts.

Methodological Evaluation of Regional Monitoring Networks in South Africa Using Difference-in-Differences for Clinical Outcomes Assessment
type: item
description: The effectiveness of regional monitoring networks in South Africa for environmental restoration has been studied extensively, but methodological evaluations are scarce. A systematic review was conducted, including studies from various regions in South Africa.

Revisiting Quasi-Experimental Designs in Off-Grid Community Systems
type: item
description: This study revisits quasi-experimental designs to evaluate off-grid community systems in Ghana's agricultural ecosystems. A replication of previous studies, this investigation employs a randomized controlled trial (RCT) with matched control groups. Key features include random assignment of communities to treatment and control groups, detailed baseline measurements, and follow-up assessments over one year. After analysing yield data from the intervention period, it was observed that communities receiving off-grid energy systems saw an average increase in crop yields by 15% compared to controls. This suggests a significant positive impact of technology on agricultural productivity. The quasi-experimental design proved robust and effective for measuring yield improvements in Ghana's agricultural settings. Future research should consider scaling up these findings with larger sample sizes and longer-term follow-up studies. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Impact of School-based Nutrition Programmes on Adolescent Health in Lagos, Nigeria
type: item
description: This study examines the impact of school-based nutrition programmes on adolescent health in Lagos, Nigeria, focusing on dietary changes and longevity improvements. The study employed a longitudinal design, tracking participants annually through pre- and post-intervention surveys, supplemented by anthropometric measurements and biomarker analyses. Data was analysed using mixed-effects models to account for individual variability and temporal trends. Nutritional programme participants showed significant dietary improvements in key nutrients such as iron and vitamin A, with a 20% higher consumption of fruits and vegetables compared to controls over the five-year period. These changes were associated with a 15% decrease in mortality rates among adolescents within the study group. The findings suggest that school-based nutrition programmes can lead to substantial dietary modifications, which in turn contribute positively to adolescent health outcomes, including longevity improvements. Schools and public health authorities should prioritise implementation of comprehensive nutrition education and fortified food initiatives to further enhance the nutritional status of adolescents in Nigeria. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
