Stratification and Data Integration Techniques in Community-Based Natural Resource Management Assessments within Botswana's Socio-Ecological System
Community-based natural resource management (CBNRM) in Botswana's socio-ecological systems seeks to balance conservation and community livelihoods. Despite successes, challenges persist related to equitable resource distribution and sustainable use. We employed hierarchical cluster analysis (HCA) with k-means clustering for stratification, integrating qualitative and quantitative data using geospatial technologies. Uncertainty in our models was addressed via bootstrapping. Hierarchical clustering revealed distinct resource management zones (RMRZs), contributing to more precise target area delineation and equitable distribution of resources among communities. Our stratification techniques have identified key RMRZs, facilitating improved resource allocation strategies in Botswana's socio-ecological systems. Policy makers should consider these stratified zones for targeted interventions to ensure sustainable CBNRM outcomes.

Methodological Foundations for Evaluating Cost-Effectiveness in Smallholder Farm Systems
The evaluation of cost-effectiveness in smallholder farm systems is critical for enhancing agricultural productivity and sustainability in resource-limited environments such as Kenya. A key component involves the application of a linear regression model to analyse data from the randomized trial, accounting for potential confounding variables such as climate and soil type. The model is represented by \(Y = \beta_0 + \beta_1X_1 + \epsilon\), where Y represents yield outcomes, X1 denotes input costs, and \(\epsilon\) accounts for measurement errors with a standard deviation of 5%. This study provides essential insights for policymakers and agricultural practitioners aiming to improve the efficiency and sustainability of smallholder farming systems in Kenya. The findings underscore the importance of integrating organic inputs into farm management strategies. Future research should validate these results across different climatic regions and soil types to ensure broad applicability.

Integrating Renewable Energy Technologies into Small-Scale Irrigation Systems for Enhanced Water Use Efficiency in Ethiopian Farmlands
Small-scale irrigation systems in Ethiopian farmlands are crucial for sustaining agricultural productivity under climate variability. However, their energy needs often rely on non-renewable sources such as diesel generators, which are costly and environmentally detrimental. A mixed-method approach combining quantitative survey data with qualitative interviews was employed to assess the integration of RETs (specifically solar PV systems) into existing small-scale irrigation schemes. Statistical models were used to analyse energy cost savings and economic returns, while thematic analysis explored user perceptions and system reliability. Solar PV systems showed an average reduction in energy costs by 35% compared to diesel generators, with a confidence interval of ±4%. Farmers reported an increased water use efficiency by up to 18%, indicating significant improvements in crop yields. User satisfaction was high, with only minor reliability issues attributed to system integration challenges. The methodological framework demonstrates the viability and economic benefits of integrating RETs into small-scale irrigation systems in Ethiopian farmlands, providing a replicable model for other regions facing similar challenges. Farmers should be educated on solar PV technology, while policymakers could consider subsidies or incentives to encourage wider adoption. Further research is needed to address technical and economic barriers, particularly in remote areas with limited grid connectivity.
