“…By finding a set of parameters that led to a model, we could forecast whether the broiler chickens are reared adequately on farms. Although other attempts to automatically grade broiler performance have been reported in the current literature [19,20], the previous studies did not encompass flock evaluation in a broader aspect as we did. Since the present results were derived from historical field data, the forecast was more related to actual data, differing from experimental tests [31].…”

“…Cutting-edge technology, involving information technology (IT), remote sensing, robotics, cloud computing, Internet of Things (IoT), and Big Data assessment, can improve livestock production, expanding the benefits of rearing environmental control [17,18]. Mobile applications (Apps) have been developed lately to help farmers monitor and assess livestock growth and production in real-time as part of the Precision Livestock development [19][20][21]. These Apps include basic statistics tools that provide indicators immediately after flock assessment and potentially calculate changes from previously collected data.…”

Broiler meat is one of the most consumed meats worldwide. The broiler production system poses several challenges for the producer, including maintaining environmental conditions for rearing. The popularization of mobile devices (smartphones) among people, including those with lower incomes, makes it possible for specialist systems to be developed and used for diverse purposes through Apps (mobile application). The present study proposed the development of a mobile application to help farmers follow up on-farm flock management. We retrieved rearing environment and flock data from commercial broiler farms that complied with broiler-producing standards and followed the breeders’ recommendations. Data were organized and normalized to serve as the basis for the software. We specified a performance index based on the average environment and flock-based data. The language used for the application development was Python compatible with the GNU GPL (General Public License), which has a vast library of ready-made functions. For the graphical interface, we selected Kivy and KivyMD framework. The developed mobile application might help farmers evaluate broiler rearing conditions on-farm during the flock’s growth and grade the flock using a performance index.

“…In deterministic method to calculate the values uses the mathematical function and the calculated value is a definite value. The second method (geostatistical method) also uses probabilistic estimates such as variance (de Oliveira Júnior et al ., 2019). The IDW interpolation method is one of the most popular for interpolation of scattered points in space, which is based on the hypothesis that at an interpolation level, the effect of a parameter on the surrounding points is not the same and more near points and fewer distant points are affected.…”

In Hungary, soil plays a fundamental role in agricultural production. The main aim of this research was to track the spatial-temporal variations in certain soil properties (soil organic carbon [So], pH, NO 3 À , P, K, Mn, Zn and Cu) between 2000 and 2010 in 55 different farms in the eastern part of Hungary (Hajdú-Bihar region). Soil data were collected from the Soil Conservation Information and Monitoring System. After 10 years of agricultural activities results reveal that the means of pH, So, NO 3 À , and Zn were higher in 2010 than in 2000. Indeed, of nine studied soil characteristics only two (So%, NO 3 À ) showed a significant change according to the Wilcoxon T-test. The average pH_H 2 O increased by 0.13 and reached 7.31 ± 0.12 in 2010. The average NO 3 À (ppm) increased by 4.75 ppm and reached 19.9 ppm in 2010. For other soil nutrients, available P, K and Mg decreased slightly, while Mn decreased from 269 ± 25 ppm to 236 ± 21 ppm in 2010. Interestingly, Zn and Cu showed no change between 2000 and 2010. However, the inverse distance weighting (IDW) showed that the central part of the study area is more prone to changes due to intensive agricultural activities. The output of this research could assist decision makers when making soil conservation plans within the study area.

“…In order to create the spatial distribution maps of some temperature-related indicators Id1, Id2, Id3, Id4, Id5, Id6) related to maximum daily temperature, minimum daily temperature and daily thermal amplitude as well as indexes (I1, I2, I3 and I vul ), the IDW interpolator was used, using p = 2 (also known as the inverse square law). The value of p = 2 is used more in works as one default value, although there is no theoretical justification to prefer this value over others (José de Oliveira Júnior et al, 2019). This interpolation method assumes that objects that are close to each other are more similar than those that are farther away (Miranda, 2010;José de Oliveira Júnior et al, 2019).…”

Air temperature conditions affect various aspects of human life through diverse pathways, such as health, agriculture, labour productivity, infrastructure and building constructions, economic production, and so on. To address better efforts at resolving this issue, decision‐making tools need to be developed to identify and prioritize areas where appropriate actions are required. The present paper identifies vulnerable areas in Morocco with a focus on three different aspects: high temperatures, low temperatures and daily temperature amplitude. Maps were created using the National Oceanic and Atmospheric Administration (NOAA)‐developed Climate Forecast System Reanalysis (CFSR) 30 year‐long daily maximum and minimum temperature data set. Several indicators as well as vulnerability indexes were defined and calculated. Maps showing the spatial distribution of these indicators were created. The results show that 78% of Morocco is considered to be non‐vulnerable areas to areas with low vulnerability; and 19% is characterized by moderate vulnerability to the effects of temperature. The remaining areas are characterized by high to extreme vulnerability: the most vulnerable areas are located in the provinces of Figuig, Jerada and Boulemane in the eastern part of the country, as well as in the provinces of Khouribga, Fquih Ben Saleh and Settat in the central part. This implies, for example, that national‐level planners in the agriculture and transport/infrastructure sectors in the central part need to take into account temperature vulnerabilities as they develop sector strategies and plans.
