Using GIS, data corresponding to the seven DRASTIC model parameters were collected and translated into seven thematic maps. The DRASTIC map was created using these maps, which describe the depth to water level (D), net recharge (R), aquifer media (A), soil media (S), topography (T), influence of the vadose zone (I), and hydraulic conductivity (C). The results obtained from this study showed that 7% of the area was classified as very-high vulnerability to pollution, 18% was classified as high vulnerability, 60% was classified as moderate vulnerability and 15% as low vulnerability. The most vulnerable areas occur around waste dumpsites, and some septic systems in residential areas. Policies should be put in place to make it easier to close possible pollution sources in high-vulnerability areas, such as open dump sites, leaking underground storage tanks at fuel stations, effluent discharge from industries, and pit latrines/sewage disposal units.</p> E.

This study evaluates the problems associated with remote sensing of urban land cover types.</p> <p><strong>Methodology:</strong> Three satellite image sensors; Disaster Monitoring Constellation (DMC), Landsat TM and colour infrared were used to investigate their potential in mapping and characterizing land cover in a part of Greater Manchester. Supervised and unsupervised image classifications were used to map urban land use and cover.</p> <p><strong>Results:</strong> The satellite image sensors and their accuracy were statistically tested to see if there is a significant relationship between them. The colour infrared image was the best in discriminating among different types of land cover with an overall accuracy of 80% followed by the Landsat image with an overall accuracy of 61% while the DMC image had the least potential in discriminating among different types of land cover with an overall accuracy of 55%.</p> <p><strong>Conclusion:</strong> The colour infrared image is the most suitable for urban land cover analysis as the misclassifications are minimal compared to the other two and the features can be vividly recognized due to its spatial resolution.</p> Rukevwe Aliogo, Felix Emeka Anyiam ##submission.copyrightStatement## https://journaljgeesi.com/index.php/JGEESI/article/view/30354 Sat, 04 Jun 2022 00:00:00 +0000 Anthropogenic Impacts on Wetlands of Kerala, India: A Review of Literature https://journaljgeesi.com/index.php/JGEESI/article/view/30355 <p>Kerala is blessed with numerous wetlands including rivers, streams, mangroves, backwaters, estuaries, canals, paddy fields, reservoirs, lakes and ponds. Wetlands are an integral part of the state and they endow man with numerous ecosystem services like purification of water, provision of food, flood protection, shoreline stabilization, support to biodiversity, recharge of underground water etc. At present wetlands are under threat as they are victims of population pressure, rapid urbanization and negligent land use pattern. Wetlands of Kerala have become polluted, fragmented and reclaimed for other purposes. If this trend continues, man is endangering not only humans but also other creatures on earth. Scientists and environmental conservationists realized the importance of wetlands and have studied the adverse effects of human activities on wetlands and have also suggested mitigation measures to conserve these fragile ecosystems. This paper is a review of published literature on the anthropogenic impacts on wetlands of Kerala and measures for their conservation.</p> Yomna P. Zainulabdeen, H.

It has fertilized a new engineering of construction postmodern cartographic knowledge based on a fivefold epistemological foundation: naturalist (descriptive epistemology), normative (prescriptive epistemology), operational (experimental epistemology), critical (radical epistemology) and activist (epistemology activist). In practice, postmodern cartographic research is implemented from the paradigm of epistemological syncretism with four postures: constructivist (qualitative variable), post-positivist (quantitative variable), systemist (quantitative and qualitative variables) and interventionist (quantitative and/or qualitative variable). The epistemological positioning here consists in adopting one of these postures and implementing its specific methodological approach. The present study thus attempts to level the deficit of epistemological framing of postmodern cartographic research, which innovates with criticality, radicality and activist-commitment, while perpetuating axiological neutrality and methodological rigor. These innovations thus seal the break with the neutrality or knurling of university activism in the modern era. In other words, cartographic postmodernism opens a new era of academic activism for radical change.</p> Meva’a Abomo Dominique ##submission.copyrightStatement## https://journaljgeesi.com/index.php/JGEESI/article/view/30356 Thu, 23 Jun 2022 00:00:00 +0000
