Methodological Assessment of Quasi-Experimental Designs in Smallholder Farm Systems within Kenya
Quasi-experimental designs are increasingly used in agricultural research to evaluate the impact of interventions on smallholder farm systems within Kenya. A comprehensive search strategy was employed across multiple databases focusing on publications from to present. Studies were screened based on predefined inclusion criteria related to smallholder farm systems in Kenya and the use of quasi-experimental methods for evaluating system reliability. The analysis revealed a predominance of studies employing difference-in-differences (DID) designs, with proportions varying from 40% to 60%, indicating DID as the most common design type. However, only 25% of these studies reported robust standard errors or confidence intervals. While quasi-experimental designs have been widely used in evaluating system reliability within Kenyan smallholder farm systems, methodological weaknesses related to lack of statistical rigor and transparency are prevalent. Future research should prioritise the reporting of robust standard errors and confidence intervals to enhance the methodological quality of studies examining system reliability.

Integrated Pest Management Strategies in Northern Kenyan Maize Farms
Integrated Pest Management (IPM) strategies have been proposed as a sustainable approach to reducing pesticide use in maize farming, particularly in regions with high pest pressure and limited resources. A total of 20 farms were randomly selected for a longitudinal study. Data was collected through regular field visits, farmer interviews, and monitoring of pest populations using visual assessment methods. Pest infestation levels decreased by an average of 35% in treated fields compared to untreated controls (p < .05), indicating the efficacy of IPM strategies but with variability across different farm conditions. IPM proved effective in reducing pest pressure and improving maize yields, although challenges related to resource availability and farmer training need further attention. Continued support for farmers through extension services is recommended to ensure consistent adoption of IPM practices. Future research should focus on long-term sustainability and cost-effectiveness.

Cost-Effectiveness and Farmer Adoption of Sustainable Irrigation Systems in South African Cattle Ranches,
South African cattle ranches face water scarcity challenges, necessitating sustainable irrigation system adoption to ensure agricultural productivity and environmental sustainability. A mixed-methods approach combining econometric analysis with survey data was employed to determine system costs, benefits, and farmer acceptance. The econometric model estimated that a per-hectare investment of $500-$700 in sustainable irrigation systems resulted in an average cost-effectiveness ratio of 1.2:1, indicating savings over conventional methods. Farmer adoption was notably higher among those with better access to credit and technical support. Sustainable irrigation systems offer a viable solution for water scarcity prevention on South African cattle ranches, but require targeted incentives to increase farmer uptake. Targeted financial assistance programmes should be implemented to encourage adoption of sustainable irrigation systems among less financially secure farmers.
