The coastal strip of the Nile delta has been vulnerable to environmental hazards. Field surveys, interpretation of Landsat enhanced thematic mapper imageries (ETM), and hydrochemistry analysis of the water samples was used as methods and materials to detect the hazards associated with climate change which threaten some natural protection coastal areas of the central part of the Nile Delta and assess its magnitude. The invasion of seawaters is the main hazard due to the impacts of global warming phenomena. Elimination of the coastal dunes which act as natural defenses has been accelerating the negative impacts that have been appearing clearly on low-lying lands. Planting that protected areas of the coastal strip are considered the most suitable ecosystem-based and most beneficial solution should be authorized and adopted by the local administration to preserve those areas and adapt to these disasters.

The current researches on risk assessment of geological disasters mainly focus on unexpected disasters such as collapses, landslides and mud-rock flows etc. As the convergence zone of land and sea, coastal zone is the most active and complex area of interactions of lithosphere, hydrosphere, atmosphere, biosphere and anthroposphere. The ecological environment of coastal zone is very fragile, so further systematical research on coastal geological hazard assessment and prevention is in urgent need. The author begins with the definition and research contents and selects three typical coastal geological disasters, namely, the seawater intrusion, coastline change and sea-level rise as the objects of study. The systematic analysis and study on assessment system and methods are conducted, hazard assessment factors are selected, and a completely set of coastal disaster assessment system is established based on the technique of GIS. We took Bao’an District of Shenzhen City as an example and carried out a case study.

Climate change brings unprecedented challenges to both the international community as well as international law. For example, extreme weather conditions might cause States to disappear and force its populations to migrate. These phenomenon creates new challenges for current international law. First, under current legal frameworks, there is no provision regarding the disappearance of a State due to climate change. Second, for people who are forced to migrate due to climate change whether caused internally or internationally, current legal framework is also unclear to whether they could be classified as refugees and to what extent should they be protected. Despite these uncertainties, people of these endangered States cannot be left to fend themselves simply because there is a legal vacuum. This paper proposes a way forward for to meet this challenge and urge the international community to use this opportunity to refine the currently existing legal regime in order to solve the various challenges posed by climate change.
