Papaya (Carica papaya L.) is a profitable fruit of
economic and food importance in Mexico and Central America. Veracruz is
the state in Mexico with the highest cultivable area, eventhough its
production presents numerous phytosanitary problems, which are being
faced with the use of the pesticide thiamethoxam. The aim of this study
was to make a diagnosis of the use and management of thiamethoxam in
papaya agroecosystems in the municipality of Cotaxtla, Veracruz. Two
surveys were applied, one to a 30% of the total number of producers
organized by an association dedicated to papaya culture, and the other
survey was through key informants, both surveys were designed using the
snowball sampling, a non-probability sampling technique. The results
indicate that 6% of papaya producers use mainly the pesticide
thiamethoxam, which belongs to the chemical group of neonicotinoids. It
was found out that for five years there have been records of
thiamethoxam use in vertisoils. During the cycle of papaya cultivation
the producers use a maximum dose of 3 L/ha and a minimum dose of 250
ml/ha per crop cycle. One hundred per cent of those who apply
thiamethoxam are not aware of its use and efficient management, nor of
the damage they are doing or have caused to agroecosystems.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
