Suitability Map

Experiments were conducted in soils of the five Upazilas, namely Atwari, Tetulia, Boda, Ranisankail and Panchagarh Sadar of Panchagarh and Thakurgaon districts of Bangladesh to assess their potentialities for tea and orange cultivation. Geographic Information Systems (GIS) based soil suitability map was prepared depending on the hydrological, land and soil characteristics. It was observed that about 86, 76 and 50% soils in Atwari, Tetulia and Panchagarh Sadar Upazilas, respectively are suitable for tea and orange cultivation. But in Boda and Ranisankail Upazilas above 60% soils are suitable for cultivation of tea and orange. Besides, five representative soil pedons, namely Bhajanpur, Ranisankail, Pirgachha, Domar and Dimla were studied and compared with the standard suitability formats. The results revealed that soils of the Thakurgaon and Panchagarh districts under the Old Himalayan piedmont plain are suitable for tea and orange cultivation. There is a vast scope of utilizing the land and soil resources of the above sites for tea and orange farming.

The Town

<p>The aim of this study was to map the optimal sites that were environmentally suitable for locating a dumpsite in the Zimbabwean town of Banket as well as investigating the suitability of the dumpsite being currently used by the Banket Town Board. Geographic Information Systems and remote sensing constituted the main quantitative techniques used in data collection. Digitizing, buffering and overlaying were used to map suitable sites for locating a dumpsite in Banket. Environmental parameters were extracted from Google Earth by way of digitizing, buffered using Quantum GIS 2.8 and then overlaid using Quantum GIS 2.8 to produce the suitability map. In support of the quantitative techniques, qualitative techniques that included interviews, questionnaires, observations and literature were used to compliment the quantitative methods. Qualitative techniques comprised of knowledge accessed through interviews from the Banket Town Board, Environmental Management Agency and literature from which significant environmental parameters were drawn and their buffer distances as well as environmental effects of the current dumpsite in Banket. Results of the research presented a suitability map which showed the possible suitable sites for establishing a dumpsite in Banket as well as the most considered suitable site in the eastern part of the town. In mapping the suitable sites according to a number of buffered parameters (Central Business District, Railway line, Road, and Rivers) the current dumpsite was found to lie within the parameters designated as unsuitable. It was recommended that Banket should consider closing its current dumpsite for a better location from the possible suitable sites established by the study especially the site on the eastern part of the town which is suitable in terms of all buffered parameters as well as other confounding variables that include economy, accessibility and elevation as well as slope.  </p>
