Remote Sensing in Crop Monitoring Across North African Regions
Remote sensing technology has been increasingly adopted in crop monitoring across various agricultural regions worldwide. In North Africa, remote sensing applications are not as extensively documented compared to other continents. This article focuses on evaluating the utility of remote sensing for crop monitoring specifically from a Beninian perspective. This study reviews existing literature on remote sensing applications in crop monitoring within the context of North Africa, focusing specifically on Benin. Methodological approaches will be evaluated based on their technical feasibility, accuracy, and relevance to agricultural practices. A key finding is that while some remote sensing techniques have shown promise for identifying early signs of crop stress or disease across different regions, their utility in Benin's specific agro-ecological conditions remains underexplored. There is a notable lack of empirical data comparing traditional methods with remote sensing. While remote sensing holds potential for enhancing crop monitoring and management in North Africa, particularly in terms of early detection of stress or disease, its adoption requires tailored approaches that account for local environmental and agricultural conditions. Future research should focus on developing localized models to better understand the effectiveness of remote sensing in Benin's diverse agro-ecological settings. Additionally, integrating remote sensing data with traditional monitoring methods could provide a more comprehensive approach to crop management.

Specifically, the use of linear regression models was prevalent, with some studies reporting confidence intervals for their effect sizes between ±10% and ±20%. This suggests that manufacturing plant interventions can reduce operational risks by a measurable amount. The review highlights the efficacy of quasi-experimental designs in assessing risk reduction strategies within Ethiopian fisheries. The use of statistical models, particularly linear regression, provides robust evidence for the effectiveness of these systems in mitigating risks. Further research should focus on replicating and validating findings through longitudinal studies and incorporating qualitative data to understand broader contextual factors affecting risk reduction outcomes.
