Climate Resilient Rice Varieties Yield Gains and Cost Savings Among Ghanaian Farmers in the Upper East Region
type: item
description: This study examines climate resilient rice varieties' impact on yield gains and cost savings among farmers in Ghana's Upper East Region. A randomized controlled trial was conducted with 100 participating farmers who were randomly assigned to either a control group (using traditional rice varieties) or an intervention group (utilising climate-resilient rice varieties). Data on yield, input costs, and financial outcomes were collected over two growing seasons. Climate resilient rice varieties demonstrated an average 25% increase in yield compared to traditional varieties, with a cost savings of $10 per hectare for the intervention group. The climate-resilient rice varieties not only improved yields but also reduced input costs significantly, providing a sustainable solution for smallholder farmers in the Upper East Region of Ghana. Farmers and agricultural extension services should be encouraged to adopt these climate-resilient rice varieties. Governments should support policies that promote their widespread adoption and provide financial incentives where necessary. climate resilience, yield gains, cost savings, rice cultivation, smallholder farmers Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Replication Study on Natural Language Processing for African Languages in Cape Verde Context
type: item
description: Natural Language Processing (NLP) is a critical area in Computer Science with applications ranging from machine translation to sentiment analysis. In Africa, particularly in Cape Verde, where multiple indigenous languages coexist, NLP research has faced challenges due to the diversity of languages and limited resources. The methodology involves re-analysing data from previous studies using established machine learning algorithms and evaluating their performance across various linguistic tasks within Cape Verdean Creole. Specific attention is given to identifying patterns that may not have been apparent in the original research. A key finding was a significant improvement (p < 0.05) in sentiment analysis accuracy when utilising a custom pre-trained model tailored for Cape Verdean Creole, indicating potential benefits of localized linguistic resources. The replication study confirms and enhances the applicability of NLP models to African languages, particularly in the context of Cape Verde. This research contributes valuable insights into resource development for under-resourced languages. Future work should focus on expanding the scope of pre-trained models to include additional Cape Verdean Creole dialects and integrate user feedback loops to refine model performance continuously.

Evaluating Climate-Resilient Agricultural Practices Among Senegalese Smallholder Women Farmers
type: item
description: Climate change poses significant challenges to agricultural productivity in Senegal, particularly affecting smallholder women farmers who rely on rain-fed agriculture. These farmers often lack access to climate-resilient practices that could enhance their resilience and sustainability. The methodology involves a mixed-methods approach combining quantitative surveys and qualitative interviews. A total of 100 smallholder women farmers were surveyed using a structured questionnaire designed to assess knowledge, attitude, and practice regarding climate-resilient agriculture. Interviews with 20 selected farmers provided in-depth insights into their experiences and challenges. The survey revealed that while over 75% of respondents had heard about climate-resilient practices, only 30% reported using them regularly. The main barriers identified were financial constraints (48%) and lack of technical knowledge (32%). This study highlights the need for targeted interventions to improve access to information and resources, thereby increasing the adoption rate of climate-resilient practices among smallholder women farmers in Senegal. Policy makers should prioritise funding for extension services and technology dissemination programmes. Additionally, capacity building initiatives focused on improving agricultural literacy and financial management skills are recommended. climate change, agriculture, resilience, women farmers, Senegal Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
