Abstract

Assessing progress towards integrated coastal zone management: some lessons from Egypt

The interface areas between marine and terrestrial environments encompass some of the most exploited and vulnerable ecosystems in the world. How these transitional environments can be effectively planned and managed has led to the creation of new planning instruments. Integrated Coastal Zone Management (ICZM) has been widely promoted as a potential mechanism for effective and integrated planning and management of these areas. However, achieving the aspirations for ICZM is complex not least because of the many human activities and diverse regulatory regimes that exist in coastal areas whose interests and concerns must be effectively integrated into a single policy and implementation regime. Within the context of the developing world countries there have been few critical and analytical evaluations of why ICZM experiments have failed. This paper seeks to begin to address this gap by suggesting that Actor Network Theory (ANT) is an appropriate analytical framework to critically evaluate why ICZM initiatives in Egypt, at both the national and local level, have been relatively unsuccessful. The critical evaluation leads to some practical recommendations that could help to enhance the implementation of ICZM in Egypt and other developing countries.

Keywords: ICZM; Actor Network Theory (ANT); Developing countries; Egypt.

Flood risk assessment and mapping in peri-urban Mediterranean environments using hydrogeomorphology. Application to ephemeral streams in the Valencia region (eastern Spain)

This paper proposes a methodology for mapping flood risk in ephemeral streams, based on assessing flood hazards and global exposure. The method has been applied to the peri-urban area of Valencia, extended over the floodplains of the Barranco del Carraixet and Rambla de Poyo catchments. Hazard was assessed using hydrogeomorphological methods. Global exposure was estimated as a combination between the economic value of land use and human exposure, following a previous study carried out by Camarasa, A.M., López, M.J. and Soriano, J., 2011. Mapping temporally variable exposure to flooding in small Mediterranean basins using land-use indicators, Applied Geography 31 (19), 136–145. Synthesis mapping was elaborated to spatially rank flood risks, in terms of their hazard and exposure components. The method is simple, effective and easily comparable. The results reveal diverse risk configurations for each floodplain, even though both are in the vicinity of Valencia city (metropolitan area). This flood risk mapping method is very useful for land-use planning because it enables swift diagnosis of the nature of risks and can support decision making by risk managers and urban planners.

The use of bottom longline on soft bottoms: An opportunity of development for fishing tourism along a coastal area of the Strait of Sicily (Mediterranean Sea)

The crisis of small-scale fisheries is causing the progressive abandonment of ancient fishing traditions and customs along a coastal area of the Strait of Sicily. For instance, worthwhile mentioning is the rapid decline in the use of bottom longline, which used to be one of the most popular gears in this area in past times. This study aims at investigating the potential of bottom longline for tourism purposes, in the perspective of recovering ancient fishing crafts. Experimental surveys were carried out to explore the effectiveness of this gear on soft bottoms, which are not usually exploited by local fishermen. An analysis of catches was carried out to assess their suitability within fishing tourism actions. The results gathered during the period of investigation demonstrate a reasonable variety of catches, with large-size specimens representing the bulk of captures. The highest values in terms of abundance and biomass were recorded for bogue Boops boops (L.) and axillary seabream Pagellus acarne (Risso). The possible enhancement of these two low commercial value species is discussed. Results also highlight the suitability of the use of bottom longline during tourism low seasons. The use of longline would produce several positive impacts in the framework of fishing tourism in the study area, such as for instance the creation of alternative sources of income for artisanal fishers, the enhancement of underexploited species in the perspective of environmental sustainability, the recovery and re-launch of a disappearing fishing gear, thus contributing to safeguard cultural diversity.

A multi-scenario forecast of urban change: A study on urban growth in the Algarve

The Algarve region in Portugal is often considered as one of the most appealing regions for tourism in the country. Its attractive location and moderate climate have since the mid-1960s brought increasing economic prosperity. As a result of the development of mass tourism, available land-use resources were widely exploited to create an integrated tourist industry. In this area, economic prosperity has led to an increasing population and a significant growth of infrastructures to cope with the demand from the hospitality sector. The far-reaching land-use changes have, however, led to high pressures on the coastal areas of the Algarve. This region has shown an increasing loss of ecosystems resulting from the expansion of urban areas. This paper proposes a dynamic assessment of urban growth in the Algarve based on non-linear complex system modelling by using cellular automata converging on qualitative story lines with quantitative spatial methodologies. This new methodology utilizes both quantitative and qualitative spatial results by a comparative validation of built scenarios, in order to highlight future land-use trends. In particular, three scenarios will be explored, each with distinct specific socio-economic paths. Our analysis to identify the scenario with the best fit, based on the evolution of the actual 2006 land cover, enabled us to build a future urban growth model for 2020 which was quantitatively assessed. The outcome suggests a picture of continuing growth for the region of the Algarve within the framework of current policies and regressive spatial trends.
