1. Theoretical background

Land use The way land is used is one of the principal drivers of environmental change, and, in turn, environmental change, particularly climate change, will increasingly influence the way we use land as communities strive to adapt to and mitigate the effects of a changing climate (Lobley and Winter, 2009). Therefore, it is easily understood that the way land is used directly affects human health and well-being, through the degradation and pollution of water, soil, and air (SOER, 2010).

Urban planning integrates land use planning and transportation planning to improve the built, economic and social environments of communities. Regional planning deals with a still larger environment, at a less detailed level. Urban planning can include urban renewal, by adapting urban planning methods to existing cities suffering from decay and lack of investment. Urban planning is also a useful method for improving local climate and human health in cities through purposefully modifying urban land surface characteristics. (eg reduce the potential risks of elevated city temperatures due to the urban heat island (Coutts et al., 2008)).

The coast can be defined in many ways. One of the most important definitions is given by the new protocol on Integrated Coastal Zone Management in the Mediterranean (2008), according to which coast "means the geomorphologic area either side of the seashore in which the interaction between the marine and land parts occurs in the form of complex ecological and resource system made up of biotic and abiotic components coexisting and interacting with human communities and relevant socio-economic activities". (UNEP/MAP, 2009b).

The coast is an extremely vulnerable area, with a limited ability to support development without serious environmental impacts. Today coasts have become overwhelmed by building too many houses, too much concrete, many docks etc. In this way we lose most of the benefits that the coasts and bays confer to us, such as fish, wildlife, recreation, clean water and of course the basis for much of the shore’s economy. The Mediterranean coastal area has always been an attractive area for development. The urbanization rate in 1995 was 62%, forecasted to grow to 72% in 2025. However, the urbanisation rate in the north will increase only from 67% to 69%, while in the south it is expected to be from 62% to 74%. But the biggest problem in continued growth in population and infrastructure is linear nature of coastal urbanization resulting in nearly 40% of the total length of the coastal area already being occupied.

In the Mediterranean, the process of coastal overdevelopment has been ongoing for several decades. It leads almost inevitably to an artificial land cover of the natural environment, whether by constructions or by restructuring. The population in the Mediterranean coastal regions grew from 95 million in 1970 to 143 million in 2000, that is 48 million additional inhabitants within 30 years, at an average annual growth rate of 1.4 %. By 2025, this population would reach 174 million inhabitants, that is 30 million additional inhabitants, at an annual growth rate of 0.8 %. The number of cities of over 10,000 inhabitants located along the coast has practically doubled within half a century, from 318 in 1950 to 584 in 1995. By 2025, the population of coastal cities would reach 90 million, that is 20 million additional city dwellers with respect to 2000, at an increase rate of 1% per year (ibid). Causes of over-development:


2. Objectives

The evolution of science, the automation, the mechanized civilization, the out of control urban and coastal development, zoning and land annexation, and also the rapid enlargement of European cities and towns, have increased concerns related to environmental stress. LitusGo efforts are focused on providing information, training and capacity building on these issues in the Mediterranean at Local level. Through this approach, LitusGo aims to improve the competences of the Mediterranean Local Authorities and NGOs to take action and decisions that promote sustainable land uses/urban planning and control coastal over-development.


3. Problems

Badly planned land uses/urban planning and coastal overdevelopment are related to a big number of problematic issues that affect our coasts, some of which are included in the lists below:

Land uses/ Urban planning:

Coastal overdevelopment:


4. How to deal with the problem

According to ICZM, effective ways to deal with the above mentioned problems are:


The 21 countries ringing the Mediterranean share problems like land use/ urban planning and coastal over-development. Some further solutions to Land use/ Urban planning and coastal over-development are given bellow:


Should the above mentioned steps be followed, the benefits will be many and multidimensional: social, economic, and environmental. The social benefits include diverse recreational opportunities, leisure and cultural activities, improving the wellbeing and the quality of life of the citizens. In addition, there will be fewer conflicts over land-use, a strengthened institutional framework, and enforced cooperation amongst stakeholders on the basis of shared objectives. In addition, information exchange and public awareness on sustainable development issues is widely raised, and encourages public participation.

The economic benefits include support for sustainable economic activities thus ensuring income in the long-run, promotion of environment-friendly technologies and cleaner production for the future markets, while value is also added to products through eco labeling schemes.

Last but not least, environment-wise, the integrity of the coastal environment and biodiversity as a natural system is ensured, as well as the sustainable use of natural resources. Habitat species and biodiversity are also preserved, pollution control is improved, as are beach fronts and soil alteration management.
