Landfills – Territorial Issues Of Cities From North-East Region, Romania, Florin C. Mihai, Pavel Ichim Dec 2013

Landfills – Territorial Issues Of Cities From North-East Region, Romania, Florin C. Mihai, Pavel Ichim

Florin C MIHAI

Landfilling prevails in waste management options in Romania like others new EU members, being contrary to the concept of waste hierarchy promoted in recent years by EC. Waste disposal is done usually in non-compliant landfills and Government established a program to close these sites. This paper aims to analyse the transition from traditional waste management systems to an integrated system at national, regional and local scale. Assessment of landfills location based on buffer analysis (using GIS techniques) is made according to the proximity of five critical factors (CF) such as: residential area, industry & commercial units, agricultural lands, rivers & …


Using Remote Sensing Data To Improve Rice Production In Kutigi, Niger State, Nigeria, Jibril Musa Phd, M B. Yunusa Dec 2012

Using Remote Sensing Data To Improve Rice Production In Kutigi, Niger State, Nigeria, Jibril Musa Phd, M B. Yunusa

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

This research work looked in the used of Remote Sensing to improve Agricultural production in Kutigi, Niger State. The aim of the study is to use remote sensing to improve rice farming activities in Kutigi, Niger State. It is very important to identify such methods to improve Agricultural production because experts are always interested in new researches and findings to better the standard of living in any environment. In view of this, Remotely-sensed data could be used or employed to elevate most of these agricultural problems in Kutigi through the following objectives: Using Landsat imagery to assess the present landuse …


Drinking Water Optimum Supply System (Dwoss) Through The Application Of Advanced Technologies, Praveen Jha Dr Oct 2009

Drinking Water Optimum Supply System (Dwoss) Through The Application Of Advanced Technologies, Praveen Jha Dr

Praveen Jha Dr

Paradigm shift in the approach for planning regarding supply of drinking water is mandatory since the current DPRs are unscientific and expensive. Planning for an optimum Drinking Water Supply System (ODWSS) that includes - optimization of Water Source Point (WSP), Water Treatment System (WTS), Water Storage Systems (WSSs), Water Distribution Points (WDP) and Water Supply Network (WSN); scientific estimation of long term demand of drinking water; minimization of physical and financial resources required for the plan implementation; water conservation and sanitation – could be done by applying several state-of-art geo-spatial programs developed by the author. Three programs - Multi-Algorithm Automation …


An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr Jan 2009

An Evaluation Of The Effect Of Land Use/Cover Change On The Surface Temperature Of Lokoja Town, Nigeria, Fanan Ujoh Mr, Olarewaju O. Ifatimehin Mr, John Y. Magaji Dr

Dr. Fanan Ujoh

This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …


Optimization Of Check Dams Through The Application Of Advanced Technologies, Praveen Jha Dr Dec 2008

Optimization Of Check Dams Through The Application Of Advanced Technologies, Praveen Jha Dr

Praveen Jha Dr

Scientific planning for conserving water and while minimizing the financial resources requirement for its implementation could be done through application of advanced technological programs developed by the author. Three state-of-art geo-spatial programs - Multi-Algorithm Automation Program (MAAP), Water Analysis Program (WAP) and Check Dam Optimization Program (CDOP) - would be used. MAAP produces land use land cover (lulc) map primarily by undertaking Digital Image Processing (DIP) of satellite data in an automated fashion using Artificial Intelligence (AI). WAP, a hydrology modeling program, would be used to generate information related to watershed, water flow, water accumulation etc. CDOP, coupled with MAAP …
