Many African countries use satellite services for communication, navigation, remote sensing and meteorology. Three of these African countries have space agencies and many others have regulatory bodies for space technology applications. This project provides an inventory of space technology service providers, promoters, users, supporters and teachers in forty four African countries. The inventory provides information about the spread of educational institutions, research centers and companies. The data collected are subdivided into seven categories namely: Government ministries, Government agencies, Educational institutions, Research centers, NGO’s, Companies and Societies/Associations. The data is presented per country in alphabetical order from Algeria to Zimbabwe.

This fact has been recorded in many studies and articles around the world. The study considered the living conditions, needs, behavior , practices of the people living in poorer societies and asks what the best option is to reduce their exposure to the effects of climate change. The case study area was Kubwa a suburb of Abuja the capital city of Nigeria. The results showed that while there is generally poor and substandard infrastructure in poorer areas, the behavior of the inhabitants increases the risk of climate change effects like flooding and erosion. The study recommends that authorities needs to provide better infrastructure and educate people on the consequences of practices such as dumping of refuse in water ways.

The models were run for the years 1998, 2005, 2006, and 2007; the data for 1998, 2006 and 2007 were flooding data while 2005 data was normal flow data. The model setup included 48 cross sections located between Lokoja and the two ends of rivers Forcados and Nun. The boundary conditions were varied downstream at the mouths of rivers Forcados and Nun using sea level rise (SLR) values adopted from the Rahmstorf predicted values; the simulations were projected for the years 2030 and 2050. Five modeling scenarios were set up to simulate the interaction of river flooding with downstream rise in sea levels. The scenarios were...

Related literature on the issue of solid waste management was reviewed, as well as theories that were pertinent and applicable for the purpose of the study. Data were collected for analysis by means of field measurements, interviews, observations. Government policy on solid waste and its implementation is considered and the problem of non availability of designated dumping sites or community waste bins is established and acknowledged as one reason for indiscriminate dumping of waste. The study makes use of geo- spatial techniques to study the present conditions and propose suitable bin sites for waste disposal in Bukuru within the constraints of an already built up area.

Within the last fifteen years the Niger delta coastal zone has experienced peak floods between September and October due to intense rains from upstream. Many studies including the United Nations Framework on Convention on Climate Change (UNFCCC) reports, indicate that the Niger delta region could be inundated with water due to the effects of climate change. According to local experts, the Niger delta is subsiding at over 25mm/annum; a situation that can exacerbate the effects of flooding and inundation in the area. 1D and 1D/2D hydrodynamic Sobek models of flooding in the Niger River were set up with discharge data as upstream boundary conditions and tidal water level data as downstream boundary conditions. The models were run for the years 1998, 2005, 2006, and 2007. The data for 1998, 2006 and 2007 ...

The assessment used GIS techniques to evaluate and analyse the indicators and the index of coastal vulnerability to floods, if sea level rise conditions are occurring. Each indicator value is based on data extracted from various sources including remote sensing, measured historical data series and literature search. Further indicators are ranked on a scale from 1 to 5 representing "very low" to "very high" vulnerability, based on their values. These ranks are used to determine a similar rank for the defined coastal vulnerability index (CV<sub>SLR</sub>I). Results indicate that 42.2% of the Niger delta is highly vulnerable to sea level rise; such areas been characterized by low slopes, low topography, high mean wave heights, and unconfined aquifers. Moreover the analys...

The common methodology is a seven step analysis that includes: delineating the study area; inventory of characteristics; identification of relevant socio-economic development factors; change assessment; formulation of response strategies; vulnerability profile assessment; and identification of future needs. The common methodology was thus used for many global studies, but after it was criticized for its limitations, especially for not catering for social factors, it was abandoned. In this paper I ask if indeed its limitations were enough to disqualify it as very good framework for sea level rise assessment. Will a modified version of it will not be idle?
