“…At 1.0 m sea-level rise, the portion of land loss attributable to inundation increases faster than the portion due to erosion. The total impacts on coastal zones increase threefold when predicted sea-level rise doubles from 0.5 to 1.0 m. Côte d'Ivoire and Egypt found that sea-level rise impacts on coastal cities have a large socio-economic impact (El Raey 1997;El Raey et al 1999).…”

Mitigation and Adaptation Strategies for Global Change

Abstract. Donor countries are providing financial and technical support for global climate change country studies to help African nations meet their reporting needs under the United Nations Framework Convention on Climate Change (UNFCCC). Technical assistance to complete vulnerability and adaptation assessments includes training of analysts, sharing of contemporary tools (e.g. simulation models), data and assessment techniques, information-sharing workshops and an international exchange programme for analysts. This chapter summarizes 14 African country studies (Botswana, Côte d'Ivoire, Egypt, Ethiopia, the Gambia, Kenya, Malawi, Mauritius, Nigeria, South Africa, Tanzania, Uganda, Zambia and Zimbabwe) assessing vulnerabilities to global climate change and identifying adaptation options. The analysis revealed that the participating African countries are vulnerable to global climate change in more than one of the following socio-economic sectors: coastal resources, agriculture, grasslands and livestock, water resources, forests, wildlife, and human health. This vulnerability is exacerbated by widespread poverty, recurrent droughts, inequitable land distribution, environmental degradation, natural resource mismanagement and dependence on rain-fed agriculture. A range of practical adaptation options were identified in key socio-economic sectors of the African nations analysed. However, underdeveloped human and institutional capacity, as well as the absence of adequate infrastructure, renders many traditional coping strategies (rooted in political and economic stability) ineffective or insufficient. Future African country studies should be more closely coordinated with development of national climate change action plans

“…The low elevation and flat relief of the Nile Delta make it a vulnerable area which is easily subjected to different environmental hazards such as shoreline retreat and sea level rise [19][20][21][22][23][24]. The combination of land subsidence and sea level rise in Hereher [22] stated that around one quarter of the Nile Delta's area would be flooded if the sealevel raises 1 m. Consequently, over two million people would be enforced to abandon their homes and around 214,000 jobs and over US $35 billion in land value, property, and tourism would be lost [27]. Furthermore, Stanley and Clemente [26] add that the construction of new dams in the upper Nile Basin will only exacerbate the problem of subsidence by reducing Nile water and sediment supply to the lower Nile Basin and Egypt's delta margin.…”

Minimizing the Residual Topography Effect on Interferograms to Improve DInSAR Results: Estimating Land Subsidence in Port-Said City, Egypt

Abstract:The accurate detection of land subsidence rates in urban areas is important to identify damage-prone areas and provide decision-makers with useful information. Meanwhile, no precise measurements of land subsidence have been undertaken within the coastal Port-Said City in Egypt to evaluate its hazard in relationship to sea-level rise. In order to address this shortcoming, this work introduces and evaluates a methodology that substantially improves small subsidence rate estimations in an urban setting. Eight ALOS/PALSAR-1 scenes were used to estimate the land subsidence rates in Port-Said City, using the Small BAse line Subset (SBAS) DInSAR technique. A stereo pair of ALOS/PRISM was used to generate an accurate DEM to minimize the residual topography effect on the generated interferograms. A total of 347 well distributed ground control points (GCP) were collected in Port-Said City using the leveling instrument to calibrate the generated DEM. Moreover, the eight PALSAR scenes were co-registered using 50 well-distributed GCPs and used to generate 22 interferogram pairs. These PALSAR interferograms were subsequently filtered and used together with the coherence data to calculate the phase unwrapping. The phase-unwrapped interferogram-pairs were then evaluated to discard four interferograms that were affected by phase jumps and phase ramps. Results confirmed that using an accurate DEM (ALOS/PRISM) was essential for accurately detecting small deformations. The vertical displacement rate during the investigated period (2007)(2008)(2009)(2010) was estimated to be −28 mm. The results further indicate that the northern area of Port-Said City has been subjected to higher land subsidence rates compared to the southern area. Such land subsidence rates might induce significant environmental changes with respect to sea-level rise.

“…The Nile delta and the adjacent areas have been subject of particular attention, and are characteristic of a high vulnerability to climate change due to natural conditions and human intervention [Milliman et al, 1989;Jeftic et al, 1992;El-Raey, 1998]. Egypt is widely dependant on resources from the Nile river and delta, in particular for water resources (90% come from the Nile).…”

“…This has forced the city to expand towards low-lying areas (the lake of Maryut) and to reclaim wetlands for agricultural purposes. Some studies have quantitatively assessed the Alexandria and adjacent coastal areas vulnerability to sea level rise using geographic information systems, remote sensing, modelling techniques and ground-based surveys [El-Raey et al, 1995, El-Raey et al, 1997, El-Raey, 1998, El-Raey et al, 1998b.…”
