Indigenous Crop Varieties and Food Security in Ethiopian Agriculture
Ethiopia faces significant challenges in achieving food security due to climate variability and population growth, necessitating a deeper understanding of indigenous crop varieties' contributions. A comparative study approach was employed, involving field surveys and data collection from 10 randomly selected districts. Data on indigenous crops' yields, genetic diversity, and resilience to environmental stresses were analysed using a linear regression model with robust standard errors to account for potential confounding variables. Indigenous crop varieties demonstrated an average yield increase of 25% compared to conventional hybrids under similar conditions, highlighting their adaptability in challenging environments. Genetic diversity analysis revealed at least three distinct genetic clusters within the indigenous crops, providing a foundation for future breeding programmes. Indigenous crop varieties play a crucial role in ensuring food security in Ethiopia's diverse agricultural landscapes through their resilience and genetic variability. Policy makers should prioritise the conservation and promotion of indigenous crop varieties to complement conventional farming practices. Investment in research on these crops is essential for developing sustainable agricultural systems.

Climate-Smart Agriculture Adoption and Impacts on Smallholder Productivity in Kenya
Climate-smart agriculture (CSA) strategies are being promoted to enhance productivity and resilience among smallholder farmers in Kenya amidst climate change challenges. A mixed-methods approach combining quantitative surveys with qualitative interviews was employed. Data were collected from 300 randomly selected farmers in four counties representing diverse agro-ecological zones. Significant differences in CSA adoption rates (75% vs. 40%) were observed across regions, with higher yields reported by farmers adopting improved irrigation techniques (mean increase: 20%). The study highlights the importance of tailored CSA interventions to maximise benefits and suggests that improved water management is a key driver of productivity gains. Local governments should prioritise investment in infrastructure for sustainable water supply systems, alongside capacity-building programmes for farmers to adopt CSA practices effectively.
