Special Issue Information

Dear Colleagues,

There is a global concern on the nature and the amplitude of threats and risks endangering coastal areas. As marine environments are extremely rich in biodiversity, the resiliency of such areas to climate change, maritime accidents, marine pollution or other natural disasters should be discussed and stimulated. There are no divergences of any order on such statements.

However the manner in which society (in general) and governments (in particular) are able to reinforce education and regulation to change behaviors to further more robust environments has caught more attention and engendered sophisticated disagreements.

How can the over-exploitation of the oceans be avoided and marine wealth used as a profitable sustainable resource? How can coastal areas be part of the normal socioeconomic activities of regions by means of tourism inputs without degradation of land and landscape? How does one face the future challenges of climate change without putting at risk the significant endeavor of industrial maritime clustering?

If solutions may be found that ease negative impacts, they should certainly be discussed on a global scale. These solutions need to engender  national and international cooperation and be based upon common sense principles and strict regulations. These solutions will drive the socioeconomic development and life quality of citizens around the world.

This Special Issue is devoted to discussing, from very different perspectives, the hindrances and the advances in safeguarding coastal areas. It also suggests policy instruments and measures that rely upon more balanced consumption patterns, higher education regarding the use of natural resources, and cooperation among stakeholders who have, in view, long-term prosperity.

We call for your contribution with case studies around the world to better illustrate the challenges faced in the above described context.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Land is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Rosetta Promontory, Egypt has been suffering from a continuous erosion problem. The dramatic retreatment was observed during the last century. It is basically due to the construction of Aswan High Dam in 1964, which reduced the flow and sediment discharges. In this paper, four Landsat images (two Thematic Mapper and two Enhanced Thematic Mapper) covering the period from 1984 to 2014 were used. These Landsat images were radio-metrically and geometrically corrected, and then, multi-temporal post-classification analysis was performed to detect land cover changes, extracting shoreline positions to estimate shoreline change rates of the Nile delta coast around Rosetta Promontory. This method provides a viable means for examining long-term shoreline changes. Four categories, including seawater, developed (agriculture and urban), sabkhas (salt-flat), and undeveloped areas, were selected to evaluate their temporal changes by comparing the four selected images. Supervised classification technique was used with support vector machine algorithm to detect temporal changes. The overall accuracy assessment of this method ranged from 97% to 100%. In addition, the shoreline was extracted by applying two different techniques. The first method is based on a histogram threshold of Band 5, and the other uses the combination of histogram threshold of Band 5 and two band ratios (Band 2/Band 4 and Band 2/Band 5). For land cover change detection from 1984 to 2014, it was found that the developed area that increased by 9% although the land in the study area has been contracted by 1.6% due to coastal erosion. The shoreline retreat rate has decreased more than 70% from 1984 to 2014. Nevertheless, it still suffers from significant erosion with a maximum rate of 37 m/year. In comparison to ground survey and different remote sensing techniques, the established trend of shoreline change extracted using histogram threshold was found to be closely consistent with these studies rather than combining band ratio with histogram threshold.
