Impacts of Ocean Acidification for the Blue-Economy in the EEZ-ECS Basin of Mauritius

R.T. Ramessur1*, R. Lollchund2, K. Boodhoo1

Increased ocean acidification can jeopardise the Ocean Economy Roadmap as it may drastically change the production pattern, volume and composition of the fishing and aquaculture sector. A number of potential areas for investment in blue economy has been identified along with necessary fiscal, regulatory and legal framework. This paper attempts to study the carbon dioxide variability and ocean acidification over the EEZ-ECS basin during the past decade and assesses its economic impact on the projected blue-economy. Rising temperatures and ocean acidification can also affect another building block of the Mauritian economy and trade.

Assessment of Groundwater quality and Hydro-Geochemical characteristics for irrigation purposes in Aswan, Egypt

M. Sharkawy1*, A. Abdelrady2, M. Saber2

Groundwater is a valuable source of water for agricultural activities in the arid and semi-arid area. Aswan region (Egypt) has more than 40 wells produce 86000 m3/day. The wastewater pollution and other pollutants reduce the quality grade of the groundwater and increase the treatment costs. This study aims to assess the groundwater quality of Elhasya City (Edfu, Aswan, Egypt), define its suitability for irrigation uses and to investigate the potential impact of untreated sewage discharges and irrigation canals on groundwater quality.

Short Essay

Warming off Carbon Dioxide?

Hans Schreuder1*

Concentrated CO2 exposed to infrared will get somewhat warmer than everyday air. But this only proves that everyday air (99.96% of which is nitrogen, oxygen and argon) is more transparent to IR and less apt to be heated that way. Air molecules, CO2 included, initially acquire heat by contact with warmer surfaces. Via mutual collisions and convective transport, this heat gets spread around within an air mass.

Case Study

Assessment of Potential Aerodrome Obstacles on Flight Safety Operations Using GIS: A Case of Murtala Mohammed International Airport, Lagos-Nigeria

Ayeni A. O1*, Musah A1, Udofia S1

The study focuses on the spatial analysis of the threat of potential Aerodrome obstacles on flight safety operations, in Murtala Mohammed airport, Ikeja Lagos state. The safety of travelling by air is an absolute pre-requisite for air transport, as it is recognized as a very safe and fastest mode of transportation worldwide. The safety of an aircraft around the vicinity of an aerodrome during approach, take-off and taxing around the manoeuvring area is very critical and of tremendous significant in flight operations. Coordinates from field survey using Differential Global Positioning System (DGPS) and administrative map of the study area, were some of the materials/data used for the study.

Exploiting Landsat ETM to Validate the Potentials of Nigeriasat-1 in Vegetation Mapping of Southwestern Nigeria

Ayeni A. O1*, B. Fashoto J. T. Taiwo1

Mapping and monitoring rainforest vegetation through remotely sensed images involves various considerations, processes and techniques. Satellite imageries are known for their differences in spectral, spatial, radioactive and temporal characteristics and thus are suitable for different mapping purposes. Achieving these purposes involve various considerations, processes and techniques. For rainforest vegetation assessment, it is important to identify discernible spectral characteristics of satellite imageries and therefore develop a preliminary vegetation classification for mapping vegetation cover.
