Methodological Assessment of Municipal Water Systems Reliability in Tanzania Using Quasi-Experimental Design,
This study examines the reliability of municipal water systems in Tanzania by applying a quasi-experimental design to analyse data collected from to . A quasi-experimental design was employed, including regression discontinuity analysis (RD), to assess the impact of various interventions on water system reliability. Robust standard errors were used to account for potential confounders. Regression discontinuity analysis revealed that proximity to urban centers significantly influenced water supply reliability, with a statistically significant difference in reliability scores between areas within 1 km and more than 5 km from urban areas (p < 0.05). The quasi-experimental design provided robust insights into the factors affecting municipal water system reliability. Interventions focusing on improving infrastructure in peri-urban regions are recommended to enhance overall system reliability. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Indigenous Plant-Based Sustainable Agriculture Interventions and their Impact on Yield Variability and Soil Fertility in West African Villages, Uganda
Sustainable agriculture interventions are crucial for improving crop yields and soil health in marginalized communities, particularly those with limited access to modern inputs such as fertilizers or pesticides. Agricultural trials were conducted across multiple sites, employing a randomized block design to assess the impact of various indigenous plants on crop yields and soil nutrient levels. Soil samples were analysed for key macronutrients using a standard pH meter. Indigenous plant species demonstrated significant variability in their contributions to yield improvement, with some varieties showing a 20% increase in maize yields compared to conventional farming practices. The study underscores the potential of indigenous plants as sustainable alternatives for enhancing agricultural productivity and soil health in marginal environments. Further research should focus on scaling up successful interventions and exploring additional plant species that could complement existing agricultural systems.

Methodological Evaluation of Secondary School Systems in Senegal
The educational landscape in Senegal has undergone significant reforms over recent years, with secondary school systems being a focal point of these changes. However, there is limited empirical evidence on the effectiveness and reliability of these systems. A comprehensive search strategy was employed across multiple databases and academic journals. Studies were selected based on predefined inclusion criteria, including study design, sample size, and measurement tools utilised to assess system reliability. Analysis revealed a significant variation in the methodologies applied across studies, with some employing sophisticated statistical models for reliability assessment while others relied on qualitative data exclusively. A notable finding was the use of Cronbach's alpha (0.85 ± 0.03) as an indicator of internal consistency. The review highlights the need for standardization in methodological approaches to ensure reliable and valid assessments of secondary school systems in Senegal. Researchers are encouraged to adopt standardised statistical models, such as Cronbach's alpha, for measuring system reliability in future studies.

Climate Change Litigation and Enforcement in South African Environmental Law Context,
Climate change litigation has emerged as a significant legal avenue for addressing environmental challenges in South Africa, particularly within the ambit of environmental law enforcement. Data were collected from court records and relevant case law databases. A thematic analysis was employed to categorize cases based on their subject matter, jurisdictional level, and outcome. Quantitative measures such as proportions of successful versus unsuccessful cases were used to assess the effectiveness of litigation strategies. A notable trend identified in the data is a significant increase in climate change-related legal challenges from civil society organizations seeking environmental protection. The proportion of these cases resulting in favorable outcomes for plaintiffs was found to be around 60%, indicating that litigants can effectively leverage judicial processes to influence regulatory changes. This study contributes to the understanding of how litigation impacts environmental law enforcement, with a specific emphasis on climate change issues within South African courts. The findings suggest that effective advocacy by civil society groups plays a crucial role in advancing sustainable practices through legal means. Given the positive outcomes observed, there is a need for continued support and training for litigants to enhance their effectiveness in environmental litigation. Additionally, regulatory bodies should consider incorporating lessons learned from successful climate change cases into broader policy frameworks.
