“…They compared its effectiveness with traditional indices and validated it through different analyses, demonstrating its sensitivity to distinguish between coffee plants ready and not ready for harvest. Felix et al [47] evaluated the seasonal behavior of five vegetation covers, including coffee, using vegetation indices, meteorological data, and surface soil moisture. They highlighted the potential and low cost of RPASs as a support tool for phenological studies, also assisting in validating satelliteimage-derived data.…”

Remotely piloted aircraft systems (RPASs) have gained prominence in recent decades primarily due to their versatility of application in various sectors of the economy. In the agricultural sector, they stand out for optimizing processes, contributing to improved sampling, measurements, and operational efficiency, ultimately leading to increased profitability in crop production. This technology is becoming a reality in coffee farming, an essential commodity in the global economic balance, mainly due to academic attention and applicability. This study presents a bibliometric analysis focused on using RPASs in coffee farming to structure the existing academic literature and reveal trends and insights into the research topic. For this purpose, searches were conducted over the last 20 years (2002 to 2022) in the Web of Science and Scopus scientific databases. Subsequently, bibliometric analysis was applied using Biblioshiny for Bibliometrix software in R (version 2022.07.1), with emphasis on the temporal evolution of research on the topic, performance analysis highlighting key publications, journals, researchers, institutions, countries, and the scientific mapping of co-authorship, keywords, and future trends/possibilities. The results revealed 42 publications on the topic, with the pioneering studies being the most cited. Brazilian researchers and institutions (Federal University of Lavras) have a strong presence in publications on the subject and in journals focusing on technological applications. As future trends and possibilities, the employment of technology optimizes the productivity and profitability studies of coffee farming for the timely and efficient application of aerial imaging.

“…The dam siltation which results the storage capacity loss is a natural phenomenon and depends on climatic conditions, relief, soil characters and land use (Costea et al, 2022;Felix et al, 2021;Chalise & Kumar, 2020;Andjelkovic et al, 2018). It is accelerated and intensified with human activity such as agricultural practices, grazing and deforestation.…”

Dam siltation has become a serious problem in arid and semi-arid countries under climate variability, where soil erosion and siltation represent a major challenge that face the industry of dams. In Morocco the policy of dam construction is one of the main keys in sustainable development, but unlikely, the dam siltation caused by soil erosion still present a big constraint. This study was carried out in the sub-basin of Tillouguite upstream the Bin El Ouidane dam in the High Atlas, in the region of Beni Mellal Khenifra, Morocco. The study aims to estimate the production of erosion material: soil losses, and the real soil losses rate -sediment yield, in Bin El Ouidane dam, using a combination of IntErO model -Intensity of Erosion and Outflow, GIS -Geographic information System and RS -Remote sensing. The study requires data which are collected from meteorological stations, soil data analysis, satellite images and observations during field missions. As a result, the production of erosion material in the Tillouguite sub-basin is estimated at 10,015,354 m³yr -1 , the coefficient of the deposit retention is estimated at 0.283, and the real soil losses rate is around 2,838,489 m³yr -1 . Given that the specific real soil losses rate is estimated at 910.02 m³km 2 yr -1 , and based on Gavrilovic classification, the sub-basin of Tellouguite is considered with a high potential of soil erosion risk, due to large bare land, and the steep land slope in the sub basin -factors that affect the storage capacity of Bin El Ouidane Dam. All the findings are a measurable indicators that are inviting policy makers to initiate appropriate measures for the protection of land degradation, all in line with the sustainable development policies in Morocco.
