Potentiality of Remote Sensing Systems and Geographical Informatics Analysis in Decision Making Process for Sustainable Development in Qalioubia Governorate
July 01, 2019



NARSS has been commissioned by the province of Qalioubia to support the province for future developmental plans. Advanced techniques of EO and remote sensing together with geographic information were integrated in an environmental study for Qalioubia province in order to maximize the use of the available resources and finding solutions to the main difficulties/problems that may hinder the developmental projects. Remote sensing data (e.g. Landsat8 & Google earth) gathered with data of field visits and laboratory measurements helped to make a scientific description of the current status and definition for the most important resources in order to propose methodologies on how to maximize their utilization. The study also identified the most important problems facing the province community and affecting their development plans.

From a complete investigation of available resources in the province of Qaluobyia, Arab Al Al-Oliqat lakes (or Abu Zaabl lakes) are regarded one of these resources that can be exploited in achieving sustainable development for the governorate, creating job opportunities for youth and civil society. Hence, the study focused on evaluating the environmental status and detecting water quality in Arab Al-Oliqat which consists of four bodies newly created. These bodies formed due to engraving and basalt ore excavation activities. Arab Al Al-Oliqat lakes lie on Al Khanka center to the south west of the province nearly latitude line 17 °30’ north and longitude line 31° 21’ east. Satellite data have been used in classifying land uses and land cover in the area surrounding the lakes along with field observations.

Water environmental parameters have been evaluated which also been confirmed by laboratory analysis for fish and water samples from lakes. The study proved that Abu Zaabl lakes divides into four separate lakes and their areas are evaluated to be 175 feddan. The results showed that the lakes suffer from a high ratio of pollution which comes mainly from sewage remnants and organic waste and this due to low geographic altitude which aids in receiving excess water from agricultural and sanitation sewage moreover its proximity to one of the landfills managed by the ministry of health. High rates of heavy metals have been evaluated in the water and fish tissues in addition to increased dissolved salts ratios and water electric conductivity which recorded 7180 mg/l and 11190 mg/l in order. Also, high rates of biochemical oxygen demand (BOD) also chemical oxygen demand (COD) which recorded 138.6 mg/l and 243.28 mg/l in order.

The results also revealed the presence of various bacterial groups with indications of sewage contamination (coliform and colon bacteria). The species of Rotifera were the most predominant for Zooplanktons (87%), while different types of phytoplankton were observed, indicating the presence of contaminants in the lake, which were confirmed by the absence of aquatic plants. As for the plants, the common plant was Phragmites species growing on the lake's edges. The Nile tilapia and catfish are the dominant species in the lake. After studying the ecosystem around the Lakes region and its components, the team suggested some proposals aimed at maximizing the utilization of the Lakes region. The proposals included converting of the water surface of the four lakes (178 acres) to fish farms in addition to the proposal to establish fish farms outside the water surface on the edges of lakes with an estimated area of about 35 acres. The study also provided the environmental requirements for the success of this proposal. Fish production was estimated at 1246 or 245 tons / 12 months of tilapia, or 534 or 105 tons / 18 months of salty fish, respectively. The study presented a complete proposal for unused areas around the lakes by using this area in the cultivation of oil trees for the production of energy such as Jatropha (short-term economy) or wood trees such as cypress and pine (for the long-term economy). The study presented similar models and indicators of the success of the proposal. The study also recommended the need to prepare economic feasibility for development proposals and assess the effectiveness of their application and the feasibility of benefiting from them and their impact on the development of the society of Qalyobia Governorate by estimating the rates of expenditure relative to the rate of benefit.

The study also included an assessment of the current status of the railway lines and the adequacy for the traffic openings services on these lines compared to the population density within the province (down to the level of the village / Sheiakha). The province of Qaluobiya has a good network of railway lines up to 121.36084 km distributed geographically well on the number of seven lines and cover all parties to the province and to other provinces. The study showed some problems in the distribution of railway openings, whether the bridges or bridges of the pedestrian in terms of selection of the preparation and location. In addition, a number of unsafe openings have been identified along the railway lines in the governorate, thus endangering the security and safety of citizens. A number of traffic accidents have been recorded due to these unsafe openings, noting that most (if not all) was carried out by the citizens themselves. The study presented a total of 16 proposals for the development of traffic openings on the railway network in the governorate, which will improve the performance and reduce the chances of traffic accidents: 1) 8 proposals for the construction of bridges for the public, 2) 4 proposals for the construction of new lanes, 3) 2 proposed to convert unsafe slots into official gliders and 4) 2 proposed to convert a wall slot into a formal crossing. The study confirmed that satellite data and spatial analysis of data are the most important tools that can support decision makers and contribute to the development plans and solutions to social problems and achieve the well-being of individuals and achieve sustainable development in society as one of the objectives of the State Strategy 2030.
