Land Suitability Assessment for Maize and Paddy Production in Bogur Microwatershed Using Remote Sensing and GIS Techniques

Land Suitability Assessment for Maize and Paddy Production in Bogur Microwatershed Using Remote Sensing and GIS Techniques



Denis Magnus Ken Amara, Philip J. Kamanda, Parameshgouda L. Patil, Augustine M. Kamara



The main aim of this study was to assess the soils of Bogur
microwatershed in Northern Transition Zone of Karnataka for sustainable
production of maize and paddy. Seven land qualities including water
availability index (W), oxygen availability (O), nutrient availability
index (NAI), water retention (I), rooting conditions (R), excess of
salts (Sa) and topography (T) were selected and their suitability
evaluated. Four soils series: Singhanhalli, Bogur, Mugli and Venkatapur
and seventeen soil units including SGH-c-d4-Be1 belonging to
Singhanhalli series; MGL-cl-d3-De2 belonging to Mugli series;
BGR1-sl-d4-Ce2, BGR2-c-d5-Be1, BGR3-sl-d4-Ce3 and BGR4-cl-d5-Ce2
belonging to Bogur series; and VKP1-sc-d4-Ce2, VKP2-sl-d3-Ee4,
VKP3-c-d5-Be1, VKP4-sl-d2-Be1, VKP5-scl-d4-De3, VKP5-scl-d3-De2,
Vkp5-scl-d4-Be2, VKP5-scl-d3-Ce2, VKP6-cl-d4-Ce2, VKP7-sl-d2-De3, and
VKP8-sl-d4-De3 belonging to Venkatapur series, were identified.
Singhanhalli series covers 78.5 ha (10.3%); Mugli series covers 22.1 ha
(2.9%); Bogur series covers 237.3 ha (31.2%); and Venkatapur series
covers 406.6 ha (53.5%). One mapping unit, VKP2-sl-d3-Ee4 which accounts
for 10.2 ha (1.3%) of the study area, was not evaluated for crop
production because it is a non-cultivable land. The results revealed
that 33.8 ha (4.4%) is moderately suitable, 312.7 ha (41.1%) is
marginally suitable and 387.7 ha (51%) is not suitable for maize;
whereas for paddy, all sixteen mapping units which account for about
734.2 ha (96.5%) of study area is marginally suitable. These results
could be used as baseline information needed for mapping specific soil
resource constraints for sustainable production of these crops in the
study area.

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...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

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...
