The purpose of this paper is to investigate residents’ perceptions, preferences and satisfaction concerning the urban green infrastructure of Kalamaria, Greece, to evaluate the importance of urban parks for residents’ well-being and to suggest management improvements.

Following a random sampling method, 385 residents were interviewed. Green infrastructure number and size, design suitability, safety, variety and care of plants, noise pollution, facilities for people with disabilities and duration and frequency of visits to green areas were among the considered parameters. Factor and hierarchical log-linear analyses were conducted.

The existing green spaces were insufficient in number, size and design, and their distribution was unsatisfactory. The facilities and equipment in the green spaces were evaluated as rather mediocre, and most respondents were unsatisfied with the overall planning and management of the green infrastructure in the municipality of Kalamaria. The results indicate that resident’s well-being relates to their satisfaction with urban green infrastructure. Frequent and longer visits of green spaces significantly improved the perceived well-being. The residents expressed an intention to pay 20-40 percent more than the average price for a house with a view of a green area.

Public perception surveys enable green infrastructure managers to identify preferred management alternatives and to use this information in an urban planning framework. Local authorities can use the results of the present survey to manage the city’s green infrastructure, enhance the city’s resilience and anticipate climate change challenges and the future needs of residents.

The purpose of this paper is to propose an approach regarding the management measures for solving environmental problems in protected areas. Two neighboring protected areas with different features were chosen in order to investigate the similarity of the environmental problems with regard to these two areas and if it is possible for these problems to be solved through a network of protected areas.

The research was carried out through the use of a questionnaire which was distributed to the inhabitants and visitors of both areas, as well as through interviews with the representatives of organizations responsible for the management and administration of those areas and representatives of the municipalities and the regional authorities these two national parks belong to. Simple random sampling was applied to the inhabitants and cluster sampling to the visitors.

The results show that with regard to the visitors the most important problem is illegal hunting while for the inhabitants equally important is the problem of pollution and cleanliness. However, those responsible with the management of the two National Parks think that the greatest threat to the wider area is the problem of floods.

The views of the stakeholders in a given time, provides us with the best possible information for solving the problems faced and can be used as a tool for increasing the effectiveness of the measures which have been taken to deal with the particular problems.
